Project description:To investigate sex differences at the transcriptome level in human pulmonary microvascular endothelial cells (HPMECs) from healthy male and female donors basally (in normoxia) and in hypoxic conditions. RNA-seq was performed on male (n=3) and female (n=4) HPMECs that were cultured in conditions of physiological shear stress (PMID: 36730645) in normoxia (21% O2) or in hypoxia (1% O2) for either 24 or 48 hours.

Project description:Comprehensive analysis of coding and non -coding transcriptome using ribo-depleted total RNA-seq and poly A selected RNA-seq of MCF-7 cells grown in hypoxia and normoxia. Breast cancer cell line (MCF-7) is cultured in normoxic condition (21% O2) and hypoxic condition (1%O2) for 24 hours. Expression of HIF-1alpha and/or HIF-2alpha subunits was suppressed using siRNAs in hypoxic MCF-7 cells. Total RNA was isolated from both hypoxia and normoxia conditions were subjected for ribosomal depleted stand specific RNA-seq and poly A selected RNA-seq

Project description:We investigated the effect of low oxygen culture on the proliferation and hair inductive capacity of human dermal papilla cells (DPCs) and dermal sheath cells (DSCs). DPCs and DSCs were cultured in atmospheric/hyperoxia (20% O2), physiological/normoxia (6% O2), or hypoxia (1% O2) conditions, respectively. Proliferation of DPCs and DSCs was highest under normoxia. Hypoxia inhibited proliferation of DPCs but enhanced proliferation of DSCs. In DPCs, hypoxia down-regulated expression of hair inductive capacity-related genes, including BMP4, LEF1, SOX2, and VCAN, and normoxia up-regulated expression of ALP. In DSCs, both normoxia and hypoxia up-regulated SOX2 expression, and hypoxia down-regulated BMP4 expression. Microarray analysis revealed increased expression of pluripotency-related genes, including SPRY, NR0B1, MSX2, IFITM1, and DAZL, under hypoxia. In an in vivo hair follicle reconstitution assay, cultured DPCs and DSCs were transplanted with newborn mouse epidermal keratinocytes into nude mice using a chamber method. In DPCs, normoxia allowed the most efficient induction of hair follicles. In DSCs, hypoxia allowed the most efficient induction and maturation of hair follicles. These results suggest that low oxygen culture enhances the proliferation and maintains functions of human DPCs and DSCs and could be used for skin engineering and clinical applications.

Project description:Neonatal mouse cardiomyocytes (NMC) were cultured in normoxia (21% O2) or hypoxia (3% O2) with and without a lentiviral shRNA-mediated knockdown of Hif1-alpha. Total RNA was extracted from NMC using RNeasy kit, cDNA was synthesized using GeneChip WT cDNA Synthesis and Amplification kit (Affymetrix 900673) and hybridised to Affymetrix mouse high-resolution AltSplice microarrays.

Project description:Tumor hypoxia affects the aggressiveness and therapy response in solid tumors, including HPV-positive cancers. Cycling hypoxia, characterized by recurrent fluctuations in oxygen supply, is a prevalent, but much less investigated form of tumor hypoxia, and has been associated with a particularly therapy-resistant cancer cell subpopulation. Using mass spectrometry-based quantitative proteome analyses, we compare SiHa cells cultivated under normoxia (21% O2), physoxia (5.5% O2), chronic hypoxia (1% O2) and cycH (repeated cycles of 1 h at 1% O2 and 1 h at 5.5% O2) and assess distinct effects of cycH on the phenotype of HPV-positive cervical cancer cells.

Project description:Purpose: The goal of this study is to investigate the role of interplay between circadian clock and oxygen-sensing pathways in determining myogenic progenitor cell fate. Methods: Total RNAs were extracted from wild-type and Bmal1-/- myoblasts following exposure to normoxia (21% O2) or hypoxia (1% O2) for 6 hours, and subjected to RNA-sequencing. Results: There were significantly up-regulated (443 in normoxia versus 477 in hypoxia) and down-regulated (745 in normoxia versus 796 in hypoxia) genes in Bmal1-/- cells compared to wild-type, with a large degree of overlap between hypoxia and normoxia, although the fold change of differential gene expression was generally greater under hypoxia versus normoxia. Conclusion: Loss of Bmal1 in myoblasts leads to a premature differentiation-prone transcriptome, which was exaggerated following exposure to hypoxia.

Project description:This study investigates the processes of angiogenesis and lymphangiogenesis in an in vitro mouse Embryoid Body (EB) model while maintaining as closely as possible an in vivo environment that is observed in human and murine placental development. Several studies have documented that human placental development is profoundly influenced by oxygen tension. Further the developing murine embryo also experiences hypoxic conditions prior to parturition, which regulates early organogenesis and embryonic blood vessel formation in vivo. Embryonic stem (ES) cells derived from 129/SvJ mice were differentiated into embryoid bodies (EBs) and were subjected to two oxygen treatments: normoxia (21% O2) and hypoxia (2.6%). Hypoxia was achieved in a humidified chamber flushed with 95% N2/5% CO2 until the oxygen level was stably maintained at 2.6%. EBs were transferred on days E8, E12, E15 and E18 to hypoxia or maintained in normoxia. After 2 days of differential oxygen treatments, these EBs were analyzed at E10, E14, E17 and E20 respectively.
