Evolving Insights on Metabolism, Autophagy, and Epigenetics in Liver Myofibroblasts
Liver myofibroblasts (MFB) are crucial mediators of extracellular matrix (ECM) deposition in liver fibrosis. They arise mainly from hepatic stellate cells (HSCs) upon a process termed "activation." To a lesser extent, and depending on the cause of liver damage, portal fibroblasts, mesothelial cells, and fibrocytes may also contribute to the MFB population. Targeting MFB to reduce liver fibrosis...

متن کاملImmediate effects of UV radiation on the skin: modification by an antioxidant complex containing carotenoids.
BACKGROUND/AIMS The ultraviolet (UV) portion of sunlight is involved in the induction and development of skin cancers against which a limited photoprotection may be provided by reduced time of exposure, clothing, and sunscreen applications. The concept of an effective, safe, systemic photoprotection will circumvent many of the shortcomings. The UV-induced oxidative stress is a cause of DNA dama...
متن کاملEvidence for UV-associated activation of telomerase in human skin.
Telomerase activation plays a crucial role in the immortalization of human cells and carcinogenesis; however, the temporal and pathophysiological aspects of the activation in vivo are poorly understood. We found telomerase activity not only in malignant tumors (91%) but also in most benign (60%) and premalignant (89%) skin tumors. This suggests the involvement of telomerase activation in a cruc...
متن کاملUV-radiation, apoptosis and skin.
Apoptosis or programmed cell death is a key function in regulating skin development, homeostasis and tumorigenesis. The epidermis is exposed to various external stimuli and one of the most important is UV radiation. The UVA and UVB spectra differ in their biological effects and in their depth of penetration through the skin layers. UVB rays are absorbed directly by DNA which results in its dama...
