Abstract

|
|
SOCS3, a suppressor of cytokine signaling 3, is known as a negative regulator of various cytokines and a tumor suppressor gene in human tumors. This study aimed to investigate the role of SOCS3 in oral squamous cell carcinoma (OSCC) and its impact on epithelial-mesenchymal transition (EMT) in OSCC cells. Although SOCS3 is recognized as a negative regulator of various cytokines and a tumor suppressor gene in human tumors, its specific effects on OSCC remain poorly understood.
For the assessment of SOCS3 expression in OSCC, the UALCAN website and TCGA data were used to evaluate its expression in head and neck cancer. Additionally, immunohistochemical staining was conducted to determine the SOCS3 expression specifically in OSCC. The findings indicated a significant decrease in SOCS3 expression in tumor tissue compared to that in normal tissues.
To investigate the enhancement of SOCS3 expression in OSCC cancer cell lines, IL6 treatment was administered to MC3 cells. However, no significant differences were observed in cell viability, wound healing assay, and invasion assay. Conversely, the transfection of SOCS3 siRNA into OSCC cells led to a notable increase in cell viability and statistically significant increases in wound healing and invasion assays. These results suggest that SOCS3 plays a crucial role in cell viability and EMT in OSCC, thereby contributing to oral carcinogenesis.
Further research is necessary to elucidate the precise role of SOCS3 in OSCC.
