Circadian disruption in cancer and regulation of cancer stem cells by circadian clock genes: An updated review.

Circadian rhythm, regulated by a time keeping system termed as the circadian clock, is important for many biological processes in eukaryotes. Disordered circadian rhythm is implicated in different human diseases, including cardiovascular disease, neurologic disease, metabolic disorders, and cancer. The stem like-cancer cells (or cancer stem cells, CSCs) are proposed to stand at the top of the heterogeneous hierarchy in different solid tumors, which are responsible for tumor initiation, development, therapy resistance and metastasis.

All-trans retinoic acid inhibits glioblastoma progression and attenuates radiation-induced brain injury.

Radiotherapy (RT) remains a primary treatment modality for glioblastoma (GBM), but it induces cellular senescence and is strongly implicated in GBM progression and RT-related injury. Recently, eliminating senescent cells has emerged as a promising strategy for treating cancer and for mitigating radiation-induced brain injury (RBI). Here, we investigated the impact of all-trans retinoic acid (RA) on radiation-induced senescence.
