Figure 4. The increased ELF3 mRNA levels in OA chondrocytes correlate with hypermethylation of the proximal promoter.

(A) Schematic representation of the proximal human ELF3 promoter sequence (−811bp to −123bp), indicating CpG site positions and percentage of methylation in non-OA and OA human primary chondrocytes, assessed by bisulfite sequencing and (B) ELF3 mRNA levels, assessed by RTqPCR in total RNA isolated from the same cell populations. ***indicates p<0.001.
