F. (top) Representative model of Fam134b∆LIR protein. LIR= LC3-Interacting-Region. (bottom) Western blot analysis of Fam134b in chondrocytes with indicated genotypes (ctrl=wild type) treated with FGF18 (50 ng/mL) for 16 hours. Representative images of N=3 biological replicates/treatment. β-actin was used as loading control. Bar graph showed quantification of Fam134b band intensity normalized to β-actin. Mean +/- standard error of the mean (sem). Student's paired T-test, *p<0.05.
