Core Tip

Core Tip: Overexpressing heat shock protein A4 (HSPA4) was significantly related to advanced pathologic TNM stage, advanced pathologic stage, progression disease status of primary therapy outcome and female subgroups with lung adenocarcinoma. In addition, increased HSPA4 expression was also found to be related to worse disease-specific survival and overall survival. Gene set enrichment analysis indicated a significant correlation between HSPA4 and cell cycle regulation and immune response, particularly through diminishing the function of cytotoxicity cells and CD8 T cells. The single-sample gene set enrichment analysis algorithm showed a positive correlation between HSPA4 expression and infiltrating levels of Th2 cells, while a negative correlation was observed with cytotoxic cell infiltration levels.
