干扰素γ诱导蛋白 30 在伴有免疫浸润的透明细胞肾细胞癌中的预后作用

Recent research has demonstrated the significance of Interferon Gamma- Inducible Protein 30 (IFI30), an interferon gamma-induced protein, in the immune response to cancerous growths. However, the relationship between IFI30 expression levels, patient prognosis, and tumor-infiltrating lymphocytes in clear cell renal cell carcinoma (ccRCC) remains inadequately defined.

To ascertain the potential link between IFI30 expression, clinical data, and overall survival (OS) in ccRCC patients, we employed diverse databases, which include TCGA, Gene Expression Profiling Interaction Analysis (GEPIA), and UALCAN. Furthermore, an in-depth analysis of the link between tumor-infiltrating immune cells (TIIC) and IFI30 was carried out using the TIMER, GEPIA, and TISIDB databases. Immunohistochemistry (IHC) was utilized to identify the IFI30 and PD-1 expression levels in a tissue microarray. Patents about molecular classification and drugs in ccRCC were reviewed through Worldwide Espacenet®.

The expression of IFI30 demonstrated a strong association with sample type, lymph node stage, tumor grade, and cancer stage. Elevated IFI30 expression was linked to unfavorable Disease- Specific Survival (DSS) and Overall Survival (OS) outcomes (p <0.01). Furthermore, overexpression of IFI30 was strongly linked to immunomodulatory molecules, chemokines, and increased infiltration of regulatory T cells (Tregs), natural killer (NK) CD56 cells, T helper 1 (Th1) cells, cytotoxic T cells, and T helper cells. IHC analysis confirmed a robust correlation between IFI30 and PD-1 expression.

IFI30 is a prognostic biomarker for ccRCC patients. Targeting IFI30 may provide new strategies for cancer therapy and improve the prognosis of ccRCC patients.
