Vincristine-resistant erythroleukemia cell line has marked increased sensitivity to hexamethylenebisacetamide-induced differentiation.

Hexamethylenebisacetamide (HMBA)-induced murine erythroleukemia (MEL) differentiation is a multistep process. Commitment is the capacity to express terminal cell division and characteristics of the differentiated phenotype even after the cells are removed from culture with inducer. Culture of MEL cell line 745A.DS19 (DS19) with HMBA causes commitment to terminal differentiation after a latent period of about 10-12 hr. Previous studies have shown that during this latent period, HMBA causes a number of metabolic changes, including modulation in expression of certain protooncogenes. We now report the development of a MEL cell line (designated V3.17) derived from DS19 that is resistant to vincristine and is (i) markedly more sensitive to HMBA, (ii) induced to commitment without a detectable latent period, and (iii) resistant to the effects of phorbol ester and dexamethasone, which are potent inhibitors of HMBA-mediated DS19 differentiation. We suggest that this V3.17 MEL cell line may express a factor that circumvents HMBA-mediated early events, which prepare the cells for commitment to terminal differentiation.[1]
