Seal the plates well. Copyright © 2020 Elsevier B.V. or its licensors or contributors. - After hybridization, remove the plate from the bag and wash samples once with 4x SSC. I: In Situ Hybridization of Frozen Sections Sections are collected on RNAse - free slides coated with TESTA, dried in air for two hours and then stored at -20deg.C. Many reagents or chemicals are used for whole mount in situ hybridization. The results demonstrate that dextran functionalized nanoparticles have no significant effect on cell viability within the tested concentrations (0.2–1 mg/mL) as compared to bare LSMO. Co-administration of harmaline (2, 5 or 15 mg/kg) remarkably potentiated the hyperthermia elicited by 5-MeO-DMT (2 or 10 mg/kg), which might be influenced by CYP2D6 status at certain dose combination. A yeast artificial chromosome (YAC) contig has been constructed in 16p12.1–p11.2 that encompasses three loci (D16S288,D16S299, andD16S298) closely linked to the gene causing Batten disease or juvenile-onset neuronal ceroid lipofuscinosis (CLN3). Also note, other fluorophores, like Cy2 (green) or Cy5 (far red) could be used for probe labeling if desired. Let the cells fix for 10 minutes, - Aspirate the paraformaldehyde and add 100% COLD methanol to each well for 10 minutes (methanol helps to permeabilize the nucleus). If the tissue is prefixed you can air-dry slides for 1-2 hours @ RT before storage @ -20 ° C. For snap-frozen fresh tissue, freeze slides on dry ice immediately after cutting sections and store slides @ -80 ° C, eg. Fluorescent in situ hybridization. We report the isolation and characterization of a novel cDNA (C170RF1), which maps centromeric to and partially within the proximal CMT1A-REP element. As the technique has been developed over time, an ever-increasing number of divergent protocols have been published. The physical map has been ordered using 42 sequence tagged sites. A higher concentration of noninvasively detected total choline-containing metabolites (tCho) and lipid CH3 localized in the tdTomato-fluorescing hypoxic regions indicated that hypoxia can upregulate tCho and lipid CH3 levels in this breast tumor model. It would be expected to promote drug efficacy, reduce therapy-resistant without introducing additional toxic side effects. RNase quickly destroys any RNA in the cell or the RNA probe itself so users must ensure they use sterile techniques, gloves, and solutions to prevent RNase contamination of the probe or tissue RNA. Nucleotide substitutions and single nucleotide deletions in exons of all identified MSPL genes on 1p36.2 mark them as pseudogenes. In contrast, tRNA precursors (pre-tRNAs) have shorter half-lives than their mature counterparts, and the ability to detect individual pre-tRNAs by in situ techniques could be problematic. Hybridization temp is 70 degrees, so are washes in 0.2 XSSC. To find other factors that facilitate tRNA export, we performed a suppressor screen of https://openwetware.org/mediawiki/index.php?title=Poly_A_RNA_in_situ_protocol&oldid=15551. Scale up or down as appropriate. Chromosomal region 1p36.2 harbors an intriguing gene cluster of about 1 Mb. Keep the samples covered from here forward, so as not to bleach the flourophore. this protocol has been used with Drosophila S2R+ cells, as well as a variety of mammalian cell types including HeLa, COS7, U2OS, N1E and N2a (mouse neuroblastomas). MSP subsequently coamplified with the other sequences in the cluster. This signal was completely competed by the addition of 1000-fold excess of unlabeled probe 04 in the … Part of C170RF1 is transcribed from the opposite strand of theCOX10partial gene duplication present in the proximal CMT1A-REP element. Ambion® Yeast tRNA purified from brewer's yeast. We have examined the cellular activation of these phosphorylation sites for the first time in situ following anoxic/hypoxic stress and IR-induced exogenous DSBs. Analysis of corresponding clusters in macaque chromosomes indicated an age for the tRNA/snRNA cluster of at least 30 MY. These findings shall provide insights into development of anxiolytic drugs and new strategies to relieve the lethal hyperthermia in serotonin toxicity. Morphology should be preserved indefinitely. Somatic cell hybrids containing the derivative chromosomes were used to determine the position of chromosome 1p and 17q DNA probes respective to the breakpoints using fluorescence in situ hybridisation. In contrast, higher doses of 5-MeO-DMT (10 and 20 mg/kg) alone caused hyperthermia. However, because the average number of genomic HDV RNA in each hepatocyte is very high (around 300,000 copies/cell) , HDV is the ideal target to be detected by a nonradioactive in situ hybridization procedure, even using a short oligonucleotide probe, i.e., representing only … - IF YOU WISH TO STAIN WITH AN ANTIBODY: dilute your primary antibody in 2xSSC + 0.1% triton-X-100 and incubate for 1 hr at RT (no need to block, as hyb solution contains BSA). Mix well, and then add 2 volumes of ethanol. Alagille syndrome (AGS, MIM 118450) is associated with human chromosome band 20p12. Herein, it is documented that tRNA aminoacylation also occurs in yeast nuclei and is important for tRNA … Store pre-hyb at -20ºC; it can be re-used many times. Protocol for in situ for total polyA mRNA localization in metazoan cell lines. Singer Lab Protocol: published online July 21, 1998. Replace pre-hyb with 0.5ml hyb containing probes (dilute probe stock 1:200). By fluorescencein situhybridization and Southern blot analysis, we assigned all tested RTS and t(8;16) translocation breakpoints to a 100-kb region. The knowledge of their tertiary structure and interactions with proteins and ribosomes is important for the understanding of mechanisms involved in protein biosynthesis. Our in vitro data are supported by irradiated xenograft studies in vivo whereby 53BP1Ser25 phosphorylation does not occur in sub-regions positive for the hypoxia marker EF5. 732-741, Radiotherapy and Oncology, Volume 99, Issue 3, 2011, pp. It is sometimes necessary to wash the slides in DEPC-PBS and three changes of DEPC-water before storing at -20deg.C. These YACs are available upon request and should be helpful in mapping studies of disease loci, e.g., Charcot-Marie-Tooth disease, Miller-Dieker syndrome, hereditary breast tumor, myotonic dystrophy, and malignant hyperthermia. Instead, store in 1… Ultrasound-mediated targeted drug delivery is a therapeutic modality under development with the potential to treat cancer. TheCOX10gene has been mapped 10 kb centromeric to the distal CMT1A-REP element, and a portion of this gene is present in both the proximal and the distal CMT1A-REP elements. Transfer RNA (tRNA) has been used in in vitro probe transcription for in situ hybridization. Reported here are the value of cavitation monitoring with a clinical system and its subsequent employment for dose optimization. Nuclear tRNA aminoacylation was proposed to provide a proof-reading step in Xenopus oocytes, ensuring nuclear export of functional tRNAs [Lund, E. & Dahlberg, J. E. (1998) Science 282, 2082–2085]. 7. New STSs were obtained from 6 isolated YAC end-fragments. ALL STEPS AND WASHES ARE PERFORMED AT ROOM TEMP UNLESS OTHERWISE SPECIFIED. - While the cells are incubating in Tris, add the probe to the appropriate amount of hybridization buffer needed for the number of samples you have. A partial genomic restriction map has been constructed to confirm the order and distances betweenD16S288andSTM.This part of the YAC contig is represented in eight cosmid contigs. 342-351, Bioorganic & Medicinal Chemistry, Volume 22, Issue 4, 2014, pp. The 1p breakpoint was localised between the PND and D1S56 loci. Dextran functionalized LSMO has the higher Specific absorption rate (SAR) value than the bare LSMO. Our in vivo tests showed that as a dual inhibitor, TEL03 dramatically inhibited tumor growth, and provided the evidence that targeting both HIF-1α and Stat3 simultaneously could be a promising strategy for breast and pancreatic cancer therapies. mix (probe dilution is arrived at empirically, however as a first approximation, dilute probe 1/200 in hyb mix. Copyright © 1991 Published by Elsevier Inc. https://doi.org/10.1016/0888-7543(91)90035-D. Depending on the detection method, ISH can be divided into chromogenic enzyme-based in situ hybridization and fluorescent in situ hybridization (FISH). This study was to define the effects of harmaline and 5-MeO-DMT on thermoregulation in wild-type and CYP2D6-humanized (Tg-CYP2D6) mice, as well as the involvement of 5-HT receptors. We constructed a phylogenetic tree of these sequences with their most likely order of origin in evolution. Novel data pertaining to the phosphorylation of 53BP1Ser25 in situ supports its dependency on the ATM kinase; but this occurs independently of p53 function. Combining heterokaryon analysis with fluorescence in situ hybridization, we show that a foreign tRNA encoded by one nucleus can move from the cytoplasm to a second nucleus that does not encode the tRNA. Note: Citric acid is used to give a final solution of pH ~5.5-6.0. 1. This page was last edited on 22 December 2005, at 14:44. - Aspirate the methanol and add 70% ethanol to each well for at least 10 minutes. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Colloids and Surfaces B: Biointerfaces, Volume 104, 2013, pp. This protocol is NOT recommended for detection of specific mRNA transcripts, because the probe is short and directly labeled with the fluorophore, so for a specific message the probe length would not be optimal and the signal would be too weak. Centrifuge for at least 15 min at ≥10,000 x g. Carefully remove the supernatant fluid, and resuspend the pellet in an appropriate buffer. However, cavitation may offer reduced treatment times, with real-time measurement of ultrasonic spectra indicating drug dose and treatment success. If using plates as opposed to coverslips or slides, it is recommended that you centrifuge the plate at 1000-1200 rpm for 1-2 minutes immediately before each aspiration step to minimize cell loss. 5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and harmaline are serotonin (5-HT) analogs often abused together, which alters thermoregulation that may indicate the severity of serotonin toxicity. Hybridization Mix Final concentration For 10 ml For 5 ml 10× salt 1 × 1 ml 500 µl Formamide 50 % 5 ml 2.5 ml Dextran Sulfate 10 % 1 g 0.5 g Yeast tRNA (10mg/ml, filtered) 1 … Incubate O/N at 70 ºC. In addition to normal high-copy-number repeats, this cluster consists entirely of locally repeated sequences among which there are tRNA and small nuclear RNA (snRNA) genes. When used at a final concentration of 10–20 µg/mL, yeast tRNA is an effective coprecipitant to aid in recovery of small amounts of nucleic acids. The MSPL sequence thus functions as a probe for the more recent primate evolution of this cluster and suggests a continuation of its unusual activity over the last 6 MY. Exogenous DSBs form discrete IR-induced foci whereas oxygen stress induced non-localized 53BP1Ser25 activation. Elevated lipid CH3 levels detected under hypoxia were caused by an increase in mobile MR-detectable lipid droplets, as demonstrated by Nile Red staining. The plate is now ready for imaging. - IF USING PLATES: Leave 25-100uL of 2x SSC in each well. - Incubate at 37 degrees for at least one hour. Magnetic fluid hyperthermia studies have been done in detail; the influence of an applied alternating current (AC) magnetic field on heat generation is presented in brief. Hybridization Buffer 50% formamide 0.75M NaCl 1X PE 100 μg/ml tRNA 0.05% heparin 1% SDS 2. In situ hybridization is used to determine the cellular distribution patterns of mRNA transcripts in paraffin- or plastic-embedded tissue sections. This can be ordered from most major oligo suppliers. This finding shows that C170RF1 andCOX10are being transcribed from opposite strands of identical DNA sequences that are separated by 1.5 Mb in the genome. Incubate embryos several hours under agitation in BSA 2 mg/ml - 2% Sheep serum in PBT Incubation with Alkaline phosphatase anti DIG antibody Dilute anti-DIG Ab to 1/5,000 - 10,000 Incubate overnight at 4°C with agitation Step 4- Washes / labelling reaction: Day 3 The increase in tCho under hypoxia was primarily due to elevated phosphocholine levels as shown by in vitro MR spectroscopy. Post-hybridization & antibody incubation (Day2): 8. Misalignment between the two elements of the CMT1A-REP binary repeat on chromosome 17p11.2–p12 causes two inherited peripheral neuropathies, Charcot–Marie–Tooth type 1A (CMT1A) and hereditary neuropathy with liability to pressure palsies. Hypoxic regions in solid tumor are spatially heterogeneous. 307-312, Neuropharmacology, Volume 89, 2015, pp. In the interest of cloning and analyzing the genes responsible for two very different diseases, the Rubinstein–Taybi syndrome (RTS) and acute myeloid leukemia (AML) associated with the somatic translocation t(8;16)(p11;p13.3), we constructed a high-resolution restriction map of contiguous cosmids (contig) covering 1.2 Mb of chromosome 16p13.3. One of these containsD16S298,predicted to be the locus closest toCLN3.The overlapping genomic clones are a valuable resource for cloning the Batten gene (CLN3) and other genes in the region. Fluorescent in situ hybridization (FISH) was performed to localize the YACs to subchromosomal regions of chromosome 1p, 17, or 19q. As such, the technique provides a high-resolution snapshot of the distribution of target transcripts in an in situ context. We have obtained a panel of 123 individual YACs with a mean size of 160 kb, and 77 of these were regionally localized by FISH: 33 to 1p, 10 to 17p, 25 to 17q, and 9 to 19q. The p53 binding protein 1 (53BP1) contains multiple ATM-consensus phosphorylation sites in its N- and C-termini and may therefore be a distal read-out of ATM function. It cannot be used in reactions inhibited by exogenous RNA, and it is the most inexpensive source of a high-quality coprecipitant. We report here the cloning, physical mapping, characterization, and full cDNA nucleotide sequence of the human CBP gene. The probe I use is a 1ug/uL stock of 5’-labeled Cy3-Oligo-dT(30). Our results indicate that co-administration of monoamine oxidase inhibitor largely potentiates 5-MeO-DMT-induced hyperthermia that involves the activation of both 5-HT1A and 5-HT2A receptors. Hybridization can continue overnight if desired. No overlapping YACs have yet been detected. Wash three times with 2x SSC, then incubate with your secondary antibody plus DAPI or Hoechst in 2xSSC + 0.1% triton-X-100. In situ hybridization of yeast cells (RNA and Oligonucleotide probes) Please reference this web site (http://www.singerlab.org/protocols) if this protocol contributes to your publication or presentation. General sample storage when using frozen sections For best results on older slides, do not store slides dry at room temperature. alone was shown to induce hypothermia that was significantly affected by CYP2D6 status. Drug uptake into breast cancer cells in the vicinity of ultrasound contrast agent was correlated with occurrence and quantity of stable and inertial cavitation, classified according to subharmonic spectra. RT-PCR analysis showed the proximal transcript was expressed in skeletal muscle. The presence of expressed sequences in both elements of the CMT1A-REP binary repeat could explain the maintenance of this repeat in humans. 10X PBS (100 ml) 1.37 M 8.00 g NaCl 27 mM 0.20 g KCl 100 mM 1.44 g Na 2HPO 4 20 mM 0.27 g KH 2PO 4 100.00 ml ddH 2O 1X PBS for in situ should be adjusted to pH 7.4. The fluorescent signal will last a month or longer. Our data were obtained with a novel three-dimensional multimodal molecular imaging platform that combines magnetic resonance (MR) imaging, MR spectroscopic imaging (MRSI), and optical imaging of hypoxia and necrosis. 6 B: Hybridization -Prehyb for at least 1 hour at 65oC in hyb. Analysis of the DNA of 18 individuals shows that the MSPL copy number is polymorphic, with a range of four to seven or more copies per haploid genome. In situ hybridization to miR-124 using DNA + LNA probes in hybridization buffers containing 2 M, 4 M, 6 M urea or 50% formamide (FA), respectively. In this paper La0.7Sr0.3MnO3 nanoparticles are synthesized and functionalized with polymer (dextran, with mean particle size ∼25 nm). A yeast artificial chromosome (YAC) library has been constructed from a somatic cell hybrid containing a t(1p;19q) chromosome and chromosome 17. Dilute this stock 1:1000 in hybridization buffer for a final concentration of 1ng/uL. RNA-fluorescence in situ hybridization (FISH) is a powerful tool to visualize target messenger RNA transcripts in cultured cells, tissue sections or whole-mount preparations. We show that 53BP1Ser25 is activated specifically in S-phase cells during anoxia in an ATM-dependent manner. We show that multiple residues of 53BP1 are phosphorylated and that these phosphoforms form discrete nuclear foci following IR or during DNA replication as exogenous or endogenous DNA double strand breaks (DSBs), respectively. )-Remove prehyb and add pre-warmed hyb mix plus probe to embryos. Nuclear-cytoplasmic tRNA transport involves multiple pathways that are segregated by the involvement of distinct proteins.

You may counterstain the cells with an antibody after the hybridization step (details are included in the protocol). The tRNA is added as a competitor to pre- and hybridization solution to prevent nonspecific binding of the probe. Chill at least 15 min at –20°C or below. Yeast cells in logarithmic growth phase in liquid culture were fixed, probed with fluorescently labeled oligodeoxynucleotides, stained with DAPI, and imaged as described previously (Long et al. 4%paraformaldehyde in PBS, pH 7.4 (make this fresh, OR make a batch and aliquot and store at -20 degrees. MSP from 3p21 could be identified as the ancestral sequence, a copy of which was captured into the cluster of tRNA and snRNA genes on 1p36.2 about 6 million years (MY) ago. Abstract. mRNA signal is stable and detectable for two weeks or longer when stored in 2x SSC at 4 degrees. - Aspirate the ethanol and add 1M Tris pH8.0 to each well for 5 minutes. Zoo blot analysis showed that the transcript is conserved in nonhuman primates. Using fluorescent in situ hybridization in the budding yeast, Saccharomyces cerevisiae,examples of nuclear pre-tRNAs are shown to reside primarily in the nucleoli. In 23 PACs and YACs from the 1p36.2 cluster, we identified eight different copies of a sequence with about 97% homology to the macrophage stimulating protein (MSP) gene located on chromosomal band 3p21. Moreover, stress-induced hyperthermia under home cage conditions was not affected by WAY-100635 but surprisingly attenuated by MDL-100907 and ketanserin. 1995;Samarsky et al. By continuing you agree to the use of cookies. - Aspirate the Tris, and add hybridization buffer with probe to each well, - Seal the plate/slides/coverslips in a plastic bag with a couple of wet kimwipes to maintain humidity. Fluorescent in situ hybridization (FISH) was performed to localize the YACs to subchromosomal regions of chromosome 1p, 17, or 19q. We also probed the RNA subunit of RNase P. The study shows that the rise in temperatures by these nanoparticles could be safely controlled around Curie temperature (Tc). ... and hybridization buffer in single-label in situ hybridization It should be good for up to one year when frozen. Previously, we hypothesised that a constitutional translocation involving the region 1p36 [t(1;17)(p36;q12–q21)] in a patient with neuroblastoma predisposed him to tumour development. After functionalization with dextran the SAR values of LSMO nanoparticles increased from 25 to 51 W/g. This binary repeat contains repetitive DNA elements that include LINES, SINES, medium reiteration frequency repeats, and a transposon-like element. If signal is less than optimal for your particular cell type or application, experiment with the probe dilution (range of 1:100-1:1500), hybridization temperature (try range of 37 – 50 degrees), and wash conditions (heating the wash solutions to the hybridization temp can reduce background). - Aspirate the PBS and add 4% paraformaldehyde (made in 1x PBS, pH7.4) to each well. Interestingly, harmaline-induced hypothermia was only attenuated by 5-HT1A receptor antagonist WAY-100635, whereas 5-MeO-DMT- and harmaline-5-MeO-DMT-induced hyperthermia could be suppressed by either WAY-100635 or 5-HT2A receptor antagonists (MDL-100907 and ketanserin). Sequence analysis identified an open reading frame encoding a 199-amino-acid protein. - Aspirate the media from each well and rinse once with PBS. Aliquot and store at -20 °C. Formamide functions as a denaturant or destabilizing agent in hybridization buffers but is undesirable to work with due to its toxic characteristics. IN SITU HYBRIDIZATION - FROZEN SECTIONS (From Nelly Polyak’s Lab) Collect 5-10 m M sections either on coated RNase-free or Superfrost/plus slides. There is little information as to the location of early tRNA biosynthesis. and localization in single cells is in situ hybridization (ISH) [18], which has increased considerably in importance in small RNA research over the last 10 years (Supplementary Figure S1). We established a YAC contig that spans the AGS region and thus will be valuable for cloning candidate genes and searching for DNA polymorphisms segregating with this syndrome. CBP functions as an integrator in the assembly of various multiprotein regulatory complexes and is thus necessary for transcription in a broad range of transduction pathways. This protocol works with cells grown on glass coverslips or chamber slides, as well as in 96- or 384- well clear bottom plates. Here, a clinical magnetic resonance imaging-guided focused ultrasound surgery system was used to study ultrasound-mediated targeted drug delivery in vitro. TEL03 blocks the expression of both HIF-1α and Stat3, regulated oncogenes (e.g., Bcl-2, VEGF, Glut1, and others) in cancer cells, and induces cancer cell apoptosis. It really should work with any cell line. The ethanol step helps to rehydrate the cells after the fixation steps. We redefined the translocation as t(1;17)(p36.31-13;q11.2–q12). tRNAs are approximately 80 nucleotides long RNA molecules with a cloverleaf shaped secondary structure and a tertiary L-shaped structure. Using fluorescence in situ hybridization, we could show that the export of some intronless tRNA species is not detectably affected by the disruption of LOS1. Intriguingly, mutations in the CBP gene are responsible for RTS as well as the t(8;16)-associated AML. Therefore, we anticipated that in situ hybridization would be sufficiently sensitive to locate a single species of mature tRNA within yeast cells. In vitro cytotoxicity of the MNPs has been assessed under Trypan blue dye exclusion and MTT assay on HeLa and L929 cell lines. It is supplied in one tube containing 0.5 mL at a concentration of 10 mg/mL. Developing an anti-cancer agent that targets two oncoproteins simultaneously is a promising strategy for accomplishing this goal. Transfer RNA (tRNA) is isolated from baker′s yeast by phenol-chloroform extraction and ethanol precipitation. 40-47, Neoplasia, Volume 14, Issue 8, 2012, pp. The human YACs distinguished by the screening were further analyzed by Alu fingerprinting and Alu PCR. Purpose. 0.3 M NaOAc). Therefore, delineating the origin and extent of hypoxia in tumors is critical. This enzyme is found on glassware, in reagents and on operators and their clothing. RNA preservation Preserving RNA is made difficult due to presence of RNase enzyme. Our recent studies have revealed that co-administration of monoamine oxidase inhibitor harmaline leads to greater and prolonged exposure to 5-HT agonist 5-MeO-DMT that might be influenced by cytochrome P450 2D6 (CYP2D6) status. It is becoming increasingly evident that improving the cure rate of many cancers will require treatment regimens hit more than one validated tumor targets. I. This total RNA preparation is supplied in ten 1 mL tubes at a concentration of 10 mg/mL in diethyl pyrocarbonate-treated distilled water. 1×Denhardt’s solution, 2×SSC, 10 mM EDTA (pH8.0), 100 μg/mL yeast tRNA, 0.01% Tween-20) at 55°C for 2 hr.

Hyperthermia offers greater potential for control, particularly with magnetic resonance imaging temperature measurement. 1mg of dry substance … We propose a model whereby DSBs induce chromatin modification at sites of DNA damage which are tracked by the ATM substrates γ H2AX and 53BP1Ser25 in a mechanism distinct from p53-mediated cell cycle arrest. A restriction map with the enzymes AscI, MluI, NotI, Sac II, and SfiI was generated, revealing seven putative CpG islands. mix (recipe below) -Dilute 100ng labeled RNA probe in hyb. The identification of flanking markers of the breakpoints is a prerequisite for breakpoint cloning and identification of a putative neuroblastoma suppressor gene. We also discovered nuclear accumulation of endogenous cytoplasmic tRNAs in haploid yeast cells in response to nutritional deprivation. Together this work indicates 53BP1Ser25, and possibly other 53BP1 phosphoforms, as a bona fide DSB-biomarkers for surveying ongoing DNA-damage related signaling in oxic and hypoxic cells during clinical radiotherapy. The resulting coated particles form a stable suspension in an aqueous environment at physiological pH and possess a narrow hydrodynamic size distribution. I also do a prehybridization in a solution containing salmon sperm DNA + yeast tRNA. In situ hybridization using probe 04 complementary to the two forms of precursor and the mature tRNA Ile UAU gave a cytosolic signal along with evidence of nuclear staining when the cells were grown at 23°C (Figure (Figure3, 3, G and H) or when incubated at 37°C for 1 or 3 h (our unpublished results). Wholemount In Situ Hybridization Solutions (Rivera lab) DEPC treatment: Add 1 ml DEPC/500 ml of solution. We have previously reported exact physical locations of these 16p breakpoints, which all disrupt one gene we mapped to this interval: the CREB-binding protein (CBP or CREBBP) gene. 1496-1505, Ultrasound in Medicine & Biology, Volume 41, Issue 7, 2015, pp. Human MDA-MB-231 breast cancer cells and tumors, which were genetically engineered to express red fluorescent tdTomato protein under hypoxic conditions, were used to investigate hypoxia.
