WNT5A and rheumatoid arthritis: The RNA sequencing (RNAseq) data from the GSE55235 series (Rheumatoid arthritis and osteoarthritis: synovial tissues, Berlin dataset) was analyzed to identify any differential expression of Inversin (INVS), Dishevelled-1 (DVL-1), α-tubulin (TUBA1A), WNT Family Member 5a (WNT5A), or WNT Family Member 5b (WNT5B) between the groups studied, considering a two-fold change as significant.
