Additional file 5: of Exosomal miR-9 inhibits angiogenesis by targeting MDK and regulating PDK/AKT pathway in nasopharyngeal carcinoma

Figure S4. MDK expression was significantly downregulated after siMDK transfection in HUVEC cells. (A) The mRNA level of MDK in HUVEC cells after siMDK transfection. (B) MDK protein expression levels in HUVEC measured by immunoblot after siMDK transfection. The intensity of each band was normalized by GAPDH. (TIF 220 kb)
