Senescent melanoma cells express an inflammatory secretome

Malignant melanoma is a highly aggressive and notoriously chemoresistant form of cancer. In this paper, Ohanna et al. reveal that anti-melanoma drugs may, paradoxically, induce a senescence-associated secretory profile ("secretome") that can ultimately promote metastasis and contribute to melanoma relapse.
