Figure 6 CircKIAA0907 worked as a tumor repressor in gastric cancer (GC) progression via the miR-452-5p-mediated KAT6B upregulation. (A, B) KAT6B was measured using western blot in HGC27 and AGS cells transfected with anti-miR-NC, anti-miR-452-5p, anti-miR-452-5p+si-NC, or anti-miR-452-5p+si-KAT6B. (C, D) Examination of proliferation ability in transfected cells implemented through 3-(4, 5-dimethylthiazol-2-y1)-2, 5-diphenyl tetrazolium bromide (MTT) assay. (E–H) Flow cytometry and western blot to evaluate cell apoptosis. (I, J) Cell cycle analysis using flow cytometry. (K, L) Cellular autophagy assessed utilizing western blot. * P<0.05.
