The Siha cell line exhibits the lowest expression of miR-137 and the highest expression of GREM1. a The miR-137 expression and mRNA expression of GREM1 in Caski, HeLa, C-33A and Siha cell lines normalized to HaCaT cells; b the gray value of GREM1 protein band in HaCaT, Caski, HeLa, C-33A and Siha cell lines normalized to β-actin; c the protein expression of GREM1 in HaCaT, Caski, HeLa, C-33A and Siha cell lines; *p < 0.05 vs. the normal epithelial cell line HaCaT; statistical data were presented as mean ± standard deviation; one-way analysis of variance was used for multi-group comparisons; the experiment was repeated 3 times independently. miR-137 microRNA-137, GREM1 gremlin-1
