Soumya et al. also found that under hypoxic conditions, the up-regulation of HIF-1α induced the activation of the Notch intracellular domain (NICD) of the transcription factor Notch, which in turn increased the …
Web近年来肝癌的发病率有所上升，尤其是肝细胞癌(HCC)，而肝癌干细胞(liver cancer stem cells，LCSC)在HCC的发生发展中起着关键作用[1]。LCSC又称为肝癌起动细胞，是一类能自我更新并分化形成肿瘤的细胞，它引发H Web19 de jun. de 2024 · Moreover, the correlation between HIF-1α levels and HLF expression was observed in patient fibrotic tissues (Figure 5D). To explore the role of HIF-1α in HSC activation, we used HIF-1α adenovirus to overexpress HIF-1α in LX-2 cells transfected with Sh-HLF or miR-98 mimics.
WebThe HSC niche refers to the specific anatomical region where the stem cells reside, but also to the regulatory microenvironment consisting of adjacent cells and factors produced by these. An important feature of the HSC niche seems to be a relatively low level of oxygen: hypoxia. Hypoxia leads to activation of Hypoxia-Inducible Factors (HIF). WebExposure to either a pan-PDGF inhibitor or a PDGFRβ-selective antagonist in the context of Hif1α stimulation blocked elevations in hematopoietic stem and progenitor cell (HSPC) …
