DNA damage induced by human CD40 ligand mutant promotes senescence and induces demethylation of GATA4 in lung cancer.

Abstract excerpt

The ligand of CD40, known as CD154 or CD40L, is the key to immunostimulatory and anticancer activity, but how CD40L affects cellular senescence is unclear. Thus, we studied a membrane‑stable mutant form CD40L (CD40L‑M) to explore tumor growth and cellular senescence in CD40‑positive NSCLC cells. We found that CD40L‑M‑expressing cells had senescent characteristics, including reduced cell proliferation and...
