Fig. 3From: Prokineticin 2 antagonist, PKRA7 suppresses arthritis in mice with collagen-induced arthritisCorrelation between arthritis scores and PK2, PKR1, and PKR2 gene expression. Severity scores were significantly correlated with a PK2 and c PKR2 gene expression levels but not with b PKR1 gene expression based on Spearman’s rank correlation coefficients (r). Data was obtained from mice sacrificed on Days 21, 28, and 35Back to article page
