DAC might inhibit the proliferation of SCLC cells and promote cell apoptosis due to antrocin, an active compound from AC fruiting bodies, which increases the level of cleaved caspase-3 and the Bax/Bcl2 ratio and downregulates the JAK/STAT signaling pathway through increasing microRNA let-7c expression [7]. The gene discussed is CASP3; the disease is small cell lung carcinoma.
