Effects of SOCS3 on the development of colon cancer via regulation of HIF-1α
Abstract
Purpose: To investigate the influence of suppressor of cytokine signaling 3 (SOCS3) on rats with colon cancer (CC).
Methods: Sprague-Dawley (SD) rats were randomly divided into CC group and control group, and then CC rat model was constructed. The expression of SOCS3 in CC tissues was determined by quantitative real time-polymerase chain reaction (qRT-PCR). Hematoxylin-eosin staining (H&E) was used to examine colon tissue morphology. Immunohistochemistry (IHC) staining assay was performed to determine the expression of SOCS3 protein in colon tissues. The contents of HIF-1α, phosphorylated phosphatidylinositol 3-hydroxy kinase (p-PI3K), and phosphorylated protein kinase B (p-AKT) proteins were determined by Western blotting (WB).
Results: Compared with that in the control group, the number of tumors in CC group was significantly increased (p < 0.05). 2). On the other hand, protein and message ribonucleic acid (mRNA) expressions of SOCS3 were down-regulated in CC group (p < 0.05). 3), while protein expressions of p-PI3K, p-AKT and HIF-1α were raised in CC group (p < 0.05).
Conclusion: SOCS3 is lowly expressed in CC rats, and promotes the expression of HIF-1α by activating PI3K/AKT signaling pathway. Thus, SOCS3 provides a therapeutic strategy for the management of colon cancer.
