HIF1A and in situ carcinoma: Overexpression of miR-624 resulted in elevation of the HIF1α, VEGF, and Survivin levels (Figure 4(f,g)) and promoted resistance to PT and CIS (Figure 4(h)), enhanced cell proliferation and invasion, and suppressed cell apoptosis in cells treated with 1 ng/mL PT (Figure 4(i,k)).
