The expression patterns of 14 target genes, including (A) 11 up-regulated and (B) 3 down-regulated genes were analyzed in one of the OA synovial tissue datasets extracted from GEO database (GSE55235). The significantly up-regulated expressions in SKAP2, KIF1B, TFAP2A, CACNA2D1 and AP1S2, and significantly down-regulated expressions in PHF21A and LPP in OA knee synovial tissues were in similar expression patterns to our HFLS-OA data. * indicated p < 0.05, ** indicated p < 0.01, *** indicated p < 0.001, and n.s. indicated no statistical significance between normal and OA groups.
