Effects of suppressor of cytokine signaling 3 (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. CC models were 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, while immunohistochemistry (IHC) staining assay was performed to determine the expression of SOCS3 protein in colon tissues. The content of HIF-1α, phosphorylated phosphatidylinositol 3-hydroxy kinase (p-PI3K), and phosphorylated protein kinase B (p-AKT) proteins was determined by Western blotting (WB).
Results: Compared with that in the control group, the number of tumors in the CC group was significantly increased (p < 0.05). Protein and messenger ribonucleic acid (mRNA) expressions of SOCS3 were down-regulated in CC group (p < 0.05), while protein expressions of p-PI3K, p-AKT and HIF-1α were significantly elevated in CC group (p < 0.05).
Conclusion: SOCS3 is poorly expressed in CC rats, and promotes the expression of HIF-1α by activating PI3K/AKT signaling pathway. The findings, thus, provide a probable strategy for management of colon cancer.
