MYC degradation-related cell cycle arrest in senescent cells

Previous Science Note

Scientists have unveiled that senescence is irreversible and that commitment to and maintenance of senescence is mediated by irreversible MYC degradation.  Thus, irreversible cell cycle exit associated with senescence is mediated by constitutive MYC degradation, but bypassing this degradation may allow tumor cells to escape during cancer initiation.

Point of Interest
- The likelihood of cells entering an irreversible state of senescence rises with time.
- Permanent cessation of the cell cycle is facilitated by the loss of MYC.
- The expression of non-degradable MYC enables senescent cells to resume division.
- Oral premalignant lesions evade oncogene-induced senescence through MYC overexpression.

Metabolic shift to glycolysis in senescenct cells

NAD(+) levels decline during the aging process, causing defects in nuclear and mitochondrial functions and resulting in many age-associated pathologies*. Here, we try to redemonstrate this phenomenon in the doxorubicin (DOX)-induced cellular senescence model with a comprehensive analysis of our products.
