Expression and effect of secondary lymphoid tissue chemokine in experimental ulcerative colitis in rats / 中华消化杂志

ABSTRACT

Objective To investigate the expression and effect of secondary lymphoid tissue chemokine(SLC)in experimental ulcerative colitis(UC)in rats.Methods Thirty Spague-Dawley rats were divided into control group and UC group.SLC expression in colon tissues was detected by RT-PCR and immunohistochemistry,respectively.Results The transcriptional level of SLC in UC tissues was significantly higher than that in the control group(0.846?0.07 vs 0.312?0.12,P＜0.01).The positive expression of SLC was concentrated mainly on submucosa,and the positive rate of SLC protein expression in UC group significantly higher than that in control group(P＜0.01).Conclusion SLC overexpression could contribute to the pathological processes in UC rats,thus SLC may be an ideal ther- apeutic target for UC.
