    AbstractEarly diagnosis of gastrointestinal tumors remains a clinical challenge due to their insidious onset. Patatin-like phospholipase domain containing protein 7 (PNPLA7) has been shown to be associated with the occurrence and development of hepatocellular carcinoma. However, the expressions of PNPLA7 in colorectal and gastric cancers remain unclear. The online gene expression profiling interactive analysis and Kaplan-Meier Plotter databases were used for the analysis of the expression of PNPLA7 and the survival curve, respectively. The tumor tissues and their corresponding normal noncancerous tissues from colorectal cancer or gastric cancer patients were collected and quantitative real-time polymerase chain reaction assay was performed to evaluate the expression of related genes. PNPLA7 was significantly down-regulated in gastric and colorectal cancer tumor tissues compared to adjacent normal tissues. Receiver operating characteristic analysis showed that PNPLA7 could be used as a diagnostic marker for gastric and colorectal tumors. The overall survival of patients with high expression of PNPLA7 was also significantly higher than that of patients with low expression in stomach and rectum adenocarcinoma. Phospholipase PNPLA7 can be used as a positive diagnostic indicator for colorectal and gastric cancers.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
