piR-39980 mediates doxorubicin resistance in fibrosarcoma by regulating drug accumulation and DNA repair
Abstract
Mallick et al. investigate the role of the piRNA, piR-39980, and doxorubicin (DOX) resistance in fibrosarcoma, finding that piR-39980 is less expressed in DOX-resistant HT1080 fibrosarcoma cells. The authors reported that its inhibition lead to attenuated intracellular DOX accumulation, DOX-indued apoptosis and anti-proliferative effects in parental HT1080 cells, as well as DNA damage by regulating RRM2 and CYP1A2.
