Reduced 2,4‐dienoyl‐CoA reductase 1 is served as an unfavorable biomarker and is related to immune infiltration in cervical cancer

Abstract

AbstractBackgroundWorldwide, cervical cancer (CC) remains the most prevalent malignancy of the female reproductive system, posing a threat to women's life and health, and increasing the medical and economic burden on society. Therefore, the search for tumor biomarkers for CC remains an important research direction. Immunotherapy has significantly improved patient outcomes, and genes related to tumor immune infiltration have been clinically relevant and highly reproducible biomarkers that affect the prognosis and response to treatment of CC. 2,4‐dienoyl‐CoA reductase 1 (DECR1) was considered to be an oncogene in a previous study, but relationship between DECR1 and immune infiltration was not mentioned. Our study aimed to reveal the clinical value of DECR1 in CC and to investigate its relationship with immune infiltration.MethodsHuman Protein Atlas was used to identify the localization of DECR1. The Ualcan database, TCGA, and IHC were used to assess the prognostic value of DECR1. GSEA was used to assess the possible signaling pathways of DECR1 in CC. The TIMER database was applied to reveal the relevance between DECR1 and immune infiltration. GEPIA was conducted to detect the co‐relationship among DECR1, immune markers, and typical molecules of apoptosis.ResultsDECR1 was mainly distributed in the cytoplasm and overlapped with the endoplasmic reticulum. DECR1 was downregulated in CC compared to adjacent tissue. Survival analysis showed that patients with lower expression of DECR1 have a worse prognosis in CC. GSEA suggested that DECR1 was closely related to apoptosis signaling. TIMER showed that DECR1 was positively correlated with CD8+ T cell and CD4+ T cell but not with B cell in CC.ConclusionDECR1 may be a potential cancer suppressor in CC and may be involved in apoptotic pathways and associated with immune infiltration.
