Comprehensive Analysis for Anti-Cancer Target-Indication Prioritization of Placental Growth Factor Inhibitor (PGF) by Use of Omics and Patient Survival Data.

The expression of the placental growth factor (PGF) in cancer cells and the tumor microenvironment can contribute to the induction of angiogenesis, supporting cancer cell metabolism by ensuring an adequate blood supply. Angiogenesis is a key component of cancer metabolism as it facilitates the delivery of nutrients and oxygen to rapidly growing tumor cells. PGF is recognized as a novel target for anti-cancer treatment due to its ability to overcome resistance to existing angiogenesis inhibitors and its impact on the tumor microenvironment. We aimed to integrate bioinformatics evidence using various data sources and analytic tools for target-indication identification of the target and prioritize the indication across various cancer types as an initial step of drug development. The data analysis included gene function, molecular pathway, protein interaction, gene expression and mutation across cancer type, survival prognosis and tumor immune infiltration association with . The overall evaluation was conducted given the totality of evidence, to target the gene to treat the cancer where the level was highly expressed in a certain tumor type with poor survival prognosis as well as possibly associated with poor tumor infiltration level. showed a significant impact on overall survival in several cancers through univariate or multivariate survival analysis. The cancers considered as target diseases for inhibitors, due to their potential effects on , are adrenocortical carcinoma, kidney cancers, liver hepatocellular carcinoma, stomach adenocarcinoma, and uveal melanoma.
