Telomeres, oxidative stress and inflammatory factors: partners in cellular senescence?
Senescence, the state of irreversible cell-cycle arrest, plays paradoxical albeit important roles in vivo: it protects organisms against cancer but also contributes to age-related loss of tissue function. The DNA damage response (DDR) has a central role in cellular senescence. Not only does it contribute to the irreversible loss of replicative capacity but also to the production and secretion o...
متن کاملHsp27 modulates p53 signaling and suppresses cellular senescence.
The small heat shock protein Hsp27 is expressed at high levels in many tumors and provides protection against anticancer drugs. Here, we show that expression of recombinant Hsp27 at elevated levels leads to protection of MCF10A human mammary epithelial cells from doxorubicin. The protection was associated with suppression of the doxorubicin-induced senescence, where Hsp27 inhibited p53-mediated...
متن کاملMetal-Induced Oxidative Stress and Cellular Signaling Alteration in Animals
Contamination by heavy metals has attracted increasing attention considering the ability of these elements in producing serious consequence to ecosystem, and especially on animals health. Due to their widespread use in human activities such as industry, agriculture and even as medicine (e.g. arsenic, selenium and platinum), numerous health risks may be associated with exposure to these substanc...
متن کاملConstitutive HER2 signaling promotes breast cancer metastasis through cellular senescence.
Senescence, a terminal cell proliferation arrest, can be triggered by oncogenes. Oncogene-induced senescence is classically considered a tumor defense barrier. However, several findings show that, under certain circumstances, senescent cells may favor tumor progression because of their secretory phenotype. Here, we show that the expression in different breast epithelial cell lines of p95HER2, a...
متن کاملSleep loss activates cellular inflammatory signaling.
BACKGROUND Accumulating evidence suggests that sleep disturbance is associated with inflammation and related disorders including cardiovascular disease, arthritis, and diabetes mellitus. This study was undertaken to test the effects of sleep loss on activation of nuclear factor (NF)-kappaB, a transcription factor that serves a critical role in the inflammatory signaling cascade. METHODS In 14...
