Figure Lengend Snippet: The effects of circ_0113656 on ox-LDL-induced HVSMC injury. (a) Circ_0113656 expression was detected by qRT-PCR in the blood samples of AS patients and healthy volunteers ( N = 17 and N = 13, respectively). (b) Circ_0113656 expression was detected by qRT-PCR in HVSMCs treated with ox-LDL (0, 25, 50, and 100 µg/mL). (c and d) The circular structure of circ_0113656 was identified by using RNase R, random primers, and oligo(dT) 18 primers. HVSMCs were divided into the ox-LDL group, ox-LDL + si-NC group, and ox-LDL + si-circ_0113656 group, with untreated HVSMCs as controls, and circ_0113656 expression was analyzed by qRT-PCR (e), cell viability by CCK-8 (f), cell proliferation by EdU assay (g), cell invasion by transwell assay (h), cell migration by wound-healing assay (i), and the protein expression of PCNA and MMP2 by Western blotting analysis (j). ** P < 0.01, *** P < 0.001, and **** P < 0.0001.
Article Snippet: After blocking the aspecific signals using skimmed milk (Yili, Beijing, China), polyvinylidene fluoride membranes with protein bands were incubated with the primary antibodies against proliferating cell nuclear antigen (PCNA) (#13-3900; 1:5000; Thermo Fisher, Waltham, MA, USA), matrix metalloprotein 2 (MMP2) (#436000; 1:250; Thermo Fisher), IGF2 (#MA5-17096; 1:1,000; Thermo Fisher), and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) (#MA1-16757; 1:2,000; Thermo Fisher).
