ABSTRACT

Objective:

To explore the expression and clinical significance of Janus protein tyrosine kinase/signal transducer and activator of transcription (JAK3/STAT5) signaling pathway in peripheral blood mononuclear cells (PBMCs) of patients with primary gouty arthritis (GA).

Methods:

Peripheral blood, clinical data and laboratory tests were collected from 50 patients with acute gout (AG), 50 patients with intermittent gout (IG) and 50 healthy controls (HC). Quantitative real-time-polymerase chain reaction (RT-qPCR) was used to detect mRNA expression level of JAK3/STAT5 related genes (JAK3, STAT5a, STAT5b). Enzyme linked immune sorbent assay (ELISA) was used to detect interleukin-2 (IL-2) concentration in subject′s plasma. Measurement data among the three groups that was in accordance with normal distribution was analyzed by one-way analysis of variance, pairwise comparisons using LSD, non-normal distribution data was analyzed by Mann-Whitney test or Kruskal-Wallis H test, and correlation analysis between variables was analyzed using Spearman correlation analysis.

Results:

① The mRNA expression levels of JAK3, STAT5a and STAT5b were significantly different among the three groups ( F=50.13, P<0.01; F=7.573, P=0.000 7; F=12.14, P<0.01), of which the JAK3 mRNA expression level in the HC group [(606±65)×10 -4] was significantly higher than that in the AG group [(103±13)×10 -4] and IG group [(114±24)×10 -4], and the difference was statistically significant (both P<0.01), while the STAT5a mRNA expression level in the AG group [(89±9)×10 -4] was significantly higher than that in the IG group [(59±4)×10 -4] and HC group [(61±4)×10 -4], and the difference was statistically significant ( P=0.002, P=0.003 9), and the expression level of STAT5b mRNA in HC group [(60±5)×10 -4] was significantly lower than that in AG group [(95±7)×10 -4] and IG group [(98±7)×10 -4], and the difference was statistically significant ( P=0.000 2, P<0.000 1). ② The difference of IL-2 concentration in plasma among the three groups was statistically significant ( F=22.87, P<0.01), and the serum IL-2 concentration in the AG group [(87.9±8.4) pg/ml] was significantly higher than that in the IG group [(32±4) pg/ml] and HC group [(44±4) pg/ml], and the difference was statistically significant (both P<0.01). ③ Spearman correlation analysis showed that the mRNA expression of STAT5a and STAT5b was positively correlated with the absolute value of neutrophils in patients with gout ( r=0.282, P<0.05; r=0.257, P<0.05).

Conclusion:

The IL-2/JAK3/STAT5 signaling pathway is involved in the occurrence and development of gout, suggesting that this pathway may play a key role in the pathogenesis of gout.
