Endothelial Cell Senescence in Marfan Syndrome: Pathogenesis and Therapeutic Potential of TGF‐β Pathway Inhibition

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Marfan syndrome (MFS) is a heritable connective tissue disorder caused by mutations in the Fibrillin‐1 gene, which encodes the extracellular matrix protein fibrillin‐1.

Resistance of Hypoxic Cells to Ionizing Radiation Is Mediated in Part via Hypoxia-Induced Quiescence

open access: yesCells, 2021
Double strand breaks (DSBs) are highly toxic to a cell, a property that is exploited in radiation therapy. A critical component for the damage induction is cellular oxygen, making hypoxic tumor areas refractory to the efficacy of radiation treatment ...

Comparative and Experimental Studies on the Genes Altered by Chronic Hypoxia in Human Brain Microendothelial Cells

open access: yesFrontiers in Physiology, 2017
Background : Hypoxia inducible factor 1 alpha (HIF1A) is a master regulator of acute hypoxia; however, with chronic hypoxia, HIF1A levels return to the normoxic levels.

Hypoxia‐induced YAP activation and focal adhesion turnover to promote cell migration in mesenchymal TNBC cells

open access: yesCancer Medicine, 2023
Background Hypoxia is commonly characterized by malignant tumors that promote the aggressiveness and metastatic potential of cancer. Triple‐negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, with approximately 46% capacity ...

Molecular responses to hypoxia in tumor cells.

open access: yesMolecular cancer, 2003
Highly aggressive, rapidly growing tumors are exposed to hypoxia or even anoxia which occurs as a consequence of inadequate blood supply. Both hypoxia and consecutive hypoxia/reoxygenation exert a variety of influences on tumor cell biology. Among these are activation of certain signal transduction pathways and gene regulatory mechanisms, induction of ...

Hypoxia, stem cells and bone tumor [PDF]

open access: yesCancer Letters, 2011
Normal oxygen level is critical for niches that together with other components of the niche play vital role in regulating stem or tumor cells behavior. Hypoxia plays an important role in normal development and disease progression, including the growth of solid tumors.

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.
