Outline
To clarify the role of acyl-CoA thioesterase 8 (ACOT8) across cancers, particularly its prognostic value, and its links to ferroptosis and the immune microenvironment in prostate cancer (PCa).
Using data from The Cancer Genome Atlas (TCGA), R software was used to analyze the gene differential expression of ACOT8 in pan-cancer and the correlation between prognosis. The single sample gene set enrichment analysis (ssGSEA), cell-type identification by estimating relative subsets of known RNA transcripts (CIBERSORT) and tumor immune dysfunction and exclusion (TIDE) algorithms were employed to assess correlations with ferroptosis and immune cell infiltration.
ACOT8 was upregulated in 11 cancers and high expression predicted poor survival, most significantly in PCa. In PCa, ACOT8 expression was negatively correlated with ferroptosis activity and positively correlated with immunosuppressive cells.
ACOT8 is a poor prognostic marker in PCa, potentially by inhibiting ferroptosis and promoting an immunosuppressive microenvironment.
