Article Title: SRPX and HMCN1 regulate cancer‑associated fibroblasts to promote the invasiveness of ovarian carcinoma.

doi: 10.3892/or.2019.7379

Figure Lengend Snippet: Figure 3. Knockdown of SRPX and HMCN1 in WS1 cells significantly reduced TOV21G cell invasion through the RhoA signaling pathway. Representative multi- ples of changes in comparisons of reverse‑transcription‑quantitative polymerase chain reaction results for (A) SRPX and (B) HMCN1 (***P<0.001). (C) Images of western blot analysis of the expression of SRPX, HMCN1, ROCK, RhoA, cdc42 and MLC in WS1 parental, mock‑transduced, SRPX‑downregulated cells (SRPX‑1 and SRPX‑2) and HMCN1‑downregulated cells (HMCN1‑1 and HMCN1‑2). Similar results were obtained from at least three independent experi- ments. Western blot analysis of HMCN1 was not performed due to no commercially available antibody. SRPX, sushi repeat‑containing protein, X; HMCN1, hemicentin 1; P, parental (normal WS1) cells; Z, mock‑transduced; RhoA, Ras homology family member A; ROCK, Rho kinase; cdc42, cell division cycle 42; MLC, myosin II regulatory light chain; ns, not significant.

Article Snippet: Protein (30 μg) from each well was dissolved in loading sample buffer under reducing conditions, separated by 12% SDS‐PAGE, and transferred to 0.2‐μm nitrocellulose membranes for immunolabelling with the following antibodies: Primary antibodies against SRPX (1:4,000, cat. co. 5473, Cell Signaling Technology, Inc.), RhoA (1:1,000, cat. co. 2117, Cell Signaling Technology, Inc.), ROCK (1:1,000, cat. co. 4035, Cell Signaling Technology, Inc.), cell division cycle 42 (cdc42) (1:1,000, cat. co. 2466, Cell Signaling Technology, Inc.), MLC (1:500, cat. co. 21157, Cell Signaling Technology, Inc.) and β‐actin (1:10,000, cat. co. MA5‐15739, Thermo Fisher Scientific, Inc.) were purchased from Novus Biologicals and incubated at 4 ̊C overnight with β‐actin as a loading control.
