Web9 de ago. de 2024 · Previous studies have shown that HIF-1α is subjected to regulation by the PI3K/Akt/mTOR ( 20, 25 ) and PI3K/Akt/FRAP ( 26) signaling pathways. The p-Akt and HIF-1α protein levels were shown to increase in response to hypoxia in human mesenchymal stem cells. Moreover, p-Akt expression peaked earlier than that of HIF-1α. All cell lines used were confirmed free from mycoplasma contamination, as determined by PCR. The human HCC cell lines HepG2 and Huh7 and lentiviral packaging line 293FT were grown in Dulbecco’s Modified Essential Media (DMEM, Hyclone), 10% fetal bovine serum (FBS, Atlanta Biologicals) or with … Ver mais Proliferation rates were assessed in cell lines by proliferation curve analysis and BrdU incorporation assays. For both assays, cells were plated on 6-cm plates in triplicate (50 × 103 … Ver mais Anchorage-independent growth assays were performed by plating 10–30 × 103cells in triplicate in 6-well plates in a mixture of media containing (0.35%) low-melt agarose over a … Ver mais To prepare samples, frozen cell pellets were lysed with lysis buffer: (20 mM) HEPES, (150 mM) NaCl, (1%) Triton X-100, (1 mM) EDTA, (1 mM) EGTA, (10 mM) sodium … Ver mais Cell death was assessed by either scoring apoptotic cells (cells with condensed or fragmented nuclei) visually at 20 × magnification after staining with the fluorescent DNA stain … Ver mais
HK2 is regulated by HIF-1 in Toxoplasma-infected cells
Web22 de out. de 2013 · There are several important regulators of metabolic pathways, such as Hexokinase 2 (HK2), PKM2 [30,31], ... Moreover, EGFR signaling upregulates PKM2 expression, which is mediated by PKCε/NF-κB activation and interaction with HIF1 α. Figure 2. EGFR signaling regulation of PKM2 in gliomas. Web19 de nov. de 2024 · The ureohydrolase, type-II arginase (Arg-II), is a mitochondrial enzyme metabolizing L-arginine into urea and L-ornithine and is highly expressed in renal proximal tubular cells (PTC) and upregulated by renal ischemia. Recent studies reported contradictory results on the role of Arg-II in renal injury. The aim of our study is to … can baby movements hurt

Web10 de abr. de 2024 · The majority of glucose in tumor cells is converted to lactate despite the presence of sufficient oxygen and functional mitochondria, a phenomenon known as the “Warburg effect” or “aerobic glycolysis”. Aerobic glycolysis supplies large amounts of ATP, raw material for macromolecule synthesis, and also lactate, thereby contributing to … WebThe kidney is particularly susceptible to ischemia/hypoxia insult while dysfunction of proximal tubular epithelial cells (PTEC) is a primary pathologic hallmark in acute kidney injury. Hypoxia-inducible factor-1 (HIF-1) is a key regulator responsible for cellular hypoxic responses. Therefore, we inv … can baby nap on stomach
