Some chemotherapeutics-treated colon cancer cells display a specific phenotype being a combination of stem-like and senescent cell features.

ABSTRACT: Colorectal cancer (CRC) is the second leading cause of death among cancer patients in the Northern countries. CRC can reappear a long time after treatment. Recent clinical studies demonstrated that, in response to chemotherapy, cancer cells may undergo stress-induced premature senescence (SIPS), which typically results in growth arrest. Nonetheless, these senescent cells were reported to divide in an atypical manner and thus contribute to cancer re-growth. Therefore, we examined if SIPS escape may follow treatment with chemotherapeutics used clinically: 5-fluorouracil (5-FU), oxaliplatin (OXA) and irinotecan (IRINO). To mimic the therapeutic regimes we exposed human colon cancer HCT116 and SW480 cells to repeated cycles of drug treatment. The cells treated with 5-FU or IRINO exhibited seve
