Increasing evidence indicates that A. capillaris can efficiently suppress the proliferation of human hepatoma cells, and ethanol extract of A. capillaris exhibits dose-dependent antiproliferative effects against Huh7 and HepG2 human hepatoma cells mediated by inhibition of cancer cell migration via interleukin-6 (IL-6)-dependent regulation of the signal transducer and activator of transcription 3 (STAT3) pathway [24]. The gene discussed is STAT3; the disease is cancer.
