Figure Lengend Snippet: Effect of LMWF on the SR-A/Wnt signaling axis and related gene expression. (A–E) After different treatments, the expression of mRNA for SR-A, CTNNB1, FZD6, TCF4, and AXIN1. (F) Representative protein expression bands for SR-A, CTNNB1, FZD6, TCF4, AXIN1, and β-actin. (G–K) Relative expression levels of SR-A, CTNNB1, FZD6, TCF4, and AXIN1 proteins compared to β-actin. Data were expressed as the means ± SD. *** p < 0.001, ** p < 0.01 and * p < 0.05 vs. DOK negative group.
