Figure Lengend Snippet: High expression of COL1A1 is associated with the clinicopathological features of OC patients. (A, B) Analysis of CHIP data (A) and RNA-Seq data (B) from the TNMplot database revealed that COL1A1 expression in OC tissue samples was significantly elevated compared to that in normal ovarian tissue (P<0.05). (C) Analysis of COL1A1 mRNA expression in the TNMplot database demonstrated a gradual increase in COL1A1 expression from normal tissues to tumor tissues and then to metastatic tissues in OC patients. (D) The relationship between the pathological stage of OC and COL1A1 expression. (E, F) Overall survival (E) and relapse-free survival (F) curves were generated for OC patients with different expression levels of COL1A1 using data from the KM plotter database. (G-I) Representative images (G) of COL1A1 IHC staining were presented, alongside statistical results of COL1A1 IHC scores in normal ovarian tissue samples (n=11) (H) , and lymph node metastasis-negative (LNM - ) and lymph node metastasis-positive (LNM + ) OC tissue samples (I) . Significant differences in COL1A1 IHC scores were observed between normal and OC tissues, as well as between LNM- and LNM+ OC tissues (normal ovarian tissue samples, n=11, LNM - tissue samples, n=11, and LNM + tissue samples, n=8. **p<0.01).
Article Snippet: The sections were then cooled to room temperature (RT) and incubated with COL1A1 primary antibody solution (Proteintech, 67288-1-Ig) for 1 hour at RT.
