International Cell Senescence Association

The association aims to promote research, co-operation and exchange of information among all those interested in any aspect of cellular senescence. 

 

Cellular senescence is a programmed state of stable cell cycle arrest that is accompanied by a complex phenotype. Senescent cells play a role in physiological processes such as tumour suppression, wound healing and embryonic development, whilst paradoxically they can contribute to ageing, cancer and age-related disease.

 

As such, the field of cellular senescence represents a multidisiplinary research topic.

Liver cancer remains difficult to treat, owing to a paucity of drugs that target critical dependencies; broad-spectrum kinase inhibitors such as sorafenib provide only a modest benefit to patients with hepatocellular carcinoma. The induction of senescence may represent a strategy for the treatment of cancer, especially when combined with a second drug that selectively eliminates senescent cancer cells (senolysis)4,5 . Here, using a kinome-focused genetic screen, we show that pharmacological inhibition of the DNA-replication kinase CDC7 induces senescence selectively in liver cancer cells with mutations in TP53. A follow-up chemical screen identified the antidepressant sertraline as an agent that kills hepatocellular carcinoma cells that have been rendered senescent by inhibition of CDC7. Sertraline suppressed mTOR signalling, and selective drugs that target this pathway were highly effective in causing the apoptotic cell death of hepatocellular carcinoma cells treated with a CDC7 inhibitor. The feedback reactivation of mTOR signalling after its inhibition6 is blocked in cells that have been treated with a CDC7 inhibitor, which leads to the sustained inhibition of mTOR and cell death. Using multiple in vivo mouse models of liver cancer, we show that treatment with combined inhibition of of CDC7 and mTOR results in a marked reduction of tumour growth. Our data indicate that exploiting an induced vulnerability could be an effective treatment for liver cancer.
