I-J. Luciferase assays in RCS chondrocytes using as promoter a 0,7kb genomic Fam134b DNA fragment containing a wild type (FAM134B-WT) or a deleted (FAM134B-mut) version of the CLEAR site. TFEB plasmid transfection amount and FGF18 (50 ng/mL for 16h) treatments are indicated. Mean +/- standard error of the mean (sem) of N=3 biological replicates. Student paired T-test *p<0.05; **p<0.005.
