HMOX1 and acute lymphoblastic leukemia: We propose that linc-PINT could reduce cell growth by upregulation of HMOX1. Moreover, we show that epigenetic drugs active in ALL, such as curcumin and panobinostat, induce linc-PINT and HMOX1 expression and produce a decrease in ALL proliferation, suggesting that linc-PINT re-expression may be one of the mechanisms exerted by these epigenetic drugs to reduce cell proliferation in ALL.
