WebHypoxia in non-small cell lung cancer (NSCLC) affects cancer progression, metastasis and metabolism. We previously showed that FAM13A was induced by hypoxia in NSCLC but the biological function of this gene has not been fully elucidated. This study aimed to investigate the role of hypoxia-induced FAM13A in NSCLC progression and metastasis. WebAug 11, 2024 · Hypoxia, the condition of insufficient oxygen, is a common feature of malignant tumors. In a majority of malignancies, the median oxygen level is about 10 mmHg, while the normal tissues have rather high oxygen pressure (between 40 and 60 mmHg) [].This phenomenon is attributed to the high oxygen demand from proliferating cancer …
WebClinically, hypoxia is associated with metastasis and poor survival in variety of cancer patients. 76–79 Hypoxia selects for cells with low apoptotic potential and increases genomic instability, allowing for rapid mutational adaptations. 80–82 In addition, hypoxia directly increases the expression of genes involved in glycolysis ... WebSep 3, 2024 · Hypoxia has been linked to elevated instances of therapeutic resistance in breast cancer. The exposure of proliferating cancer cells to hypoxia has been shown to induce an aggressive phenotype conducive to invasion and metastasis. Regions of the primary tumors in the breast may be exposed to different types of hypoxia including …
WebApr 12, 2024 · Hypoxia is associated with numerous tumor hallmarks, such as cell proliferation, angiogenesis, metabolic reprogramming, and radiation resistance, and can also induce EMT and ROS phenotypes in advanced tumor cells, thus promoting cell invasion and metastasis [31,32, 33]. WebObjective: To identify and characterize read-through RNAs and read-through circular RNAs (rt-circ-HS) derived from transcriptional read-through hypoxia inducible factor 1α (HIF1α) and small nuclear RNA activating complex polypeptide 1 (SNAPC1) the two adjacent genes located on chromosome 14q23, in renal carcinoma cells and renal carcinoma tissues, …
WebJun 3, 2024 · Hypoxia, a common feature of the tumor microenvironment in various types of cancers, weakens cytotoxic T cell function and causes recruitment of regulatory T cells, thereby reducing tumoral immunogenicity. Studies have demonstrated that hypoxia and hypoxia-inducible factors (HIFs) 1 and 2 alpha (HIF1A and HIF2A) are involved in tumor …
