The predictive prognostic values of CBFA2T3, STX3, DENR, EGLN1, FUT4, and PCDH7 in lung cancer

Abstract

Background: Lung cancer is one of the most malignant tumors. However, neither the pathogenesis of lung cancer nor the prognosis markers are completely clear. The purpose of this study is to screen the diagnostic or prognostic markers of lung cancer.Methods: TCGA and GEO datasets were used to analyze the relationship between lung cancer-related genes and lung cancer samples. Common differential genes were screened, and a univariate Cox regression analysis was used to screen survival related genes. A univariable Cox proportional hazards regression analysis was used to verify the genes and construct risk model. The key factors affecting the prognosis of lung cancer were determined by univariate and multivariate regression analyses. The ROC curve, AUC and the survival of each risk gene was analyzed. Finally, the biological functions of high-and low-risk patients were explored by GSEA and an immune-infiltration analysis.Results: Based on the common differential genes, 13 genes significantly related to lung cancer survival were identified. Eight risk genes (CBFA2T3, DENR, EGLN1, FUT2, FUT4, PCDH7, PHF14, and STX3) were screened out. The results showed that risk status may be an independent prognostic factor, and the risk score predicted the prognosis of lung cancer. CBFA2T3 and STX3 are protective genes, while DENR, EGLN1, FUT4 and PCDH7 are dangerous genes. These 6 genes can be used as independent lung cancer prognosis markers. The corresponding biological functions of genes expressed in high-risk patients were mostly related to tumor proliferation and inflammatory infiltration. Neutrophil, CD8 + T, Macrophage M0, Macrophage M1-and mDC-activated cells were high in high-risk status samples.Conclusions: CBFA2T3, STX3, DENR, EGLN1, FUT4, and PCDH7 are important participants in the occurrence and development of lung cancer. High-risk patients display serious inflammatory infiltration.This study not only provides insight into the mechanism of occurrence and development of lung cancer, but also provides potential targets for targeted therapy of lung cancer.

The roles of protocadherin-7 in colorectal cancer cells on cell proliferation and its chemoresistance

“…Although numerous previous reports have illustrated the promotion of lung and breast cancer cell migration and invasion by PCDH7 ( Chen et al, 2021 ), the increase in this protein inhibits cell migration and invasion in gastric cancer cells. However, a recent study has shown that P7 could promote lung metastasis of colorectal cancer ( Liu et al, 2022 ), which seems contrary to our results, but we consider that this is related to different cell lines and experimental systems.…”

Identification of hub genes distinguishing subtypes in endometrial stromal sarcoma through comprehensive bioinformatics analysis

“…Its roles vary. PCDH7 was defined as a risk gene, and its high expression suppressed survival in lung cancer patients in a study by Chen Y et al 29 . PCDH7 provides a potential therapeutic strategy in colon cancer: it can inhibit the MEK1/2/ERK/c-Fos axis by knocking down PCDH7, induce neurogenesis and autophagy, and enhance the effect of colon cancer cells on chemotherapy 30 .…”

Identification of Tumor Antigens and Immune Subtypes in Lung Adenocarcinoma for mRNA Vaccine Development

“…Therefore, using KLRG1 as a tumor antigen, APCs will be trained to recognize and remove KLRG1-expressing tumor cells and senescent immune cells, becoming a new LUAD treatment strategy. CBFA2T3 has been reported as a tumor suppressor in lung cancer and can be an independent prognostic marker in LUAD ( Zhang et al, 2018 ; Chen et al, 2021 ). Furthermore, we showed that CBFA2T3 expression was positively correlated with higher antigen-presenting cell infiltration.…”
