A comprehensive analysis-based study of triphenyl phosphate-environmental explanation of glioma progression

Published on Friday, 02 December 2022

Abstract

As BFRs have gradually been banned recently, organophosphorus flame retardants (OPFRs) have been manufactured and used in their place. Although OPFRs are considered the better alternatives to BFRs, many studies have discovered that OPFRs may be associated with various cancers, including prostate cancer, bladder cancer, hepatocellular carcinoma, and colorectal cancer. However, few studies have examined the relationship between OPFRs and gliomas.

This study investigated the relationship between triphenyl phosphate (TPP) and glioma using bioinformatics analysis approaches. The comparative toxicogenomics database (CTD) and The Cancer Genome Atlas (TCGA) databases were accessed for TPP-related genes and gene expression data from glioma patients. The Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses show that TPP might be closely related to many pathways. Further, the analysis of protein-protein interactions revealed strong intrinsic relationships between TPP-related genes.

In addition, the TPP-based prognostic prediction model demonstrated promising results in predicting the prognosis of patients with gliomas. Several TPP-related genes were closely related to glioma patients' overall survival rates. The proliferation and migration abilities of glioma cells were further demonstrated to be significantly enhanced by TPP. In a bioinformatics analysis, we also discovered that melatonin is highly correlated with the presence of TPP and gliomas.

According to the cell proliferation and migration assays, exposure to melatonin and TPP inhibited the ability of glioma cells to invade compared with the TPP group.

- Melatonin use in cancer patients have started in 1974, when melatonin prepared according to Prof. Di Bella’s formulation [...]. For 11 days was administered to the patient, admitted to the general medical ward at the Maggiore-Pizzardi Hospital in Bologna, very slowly (over approx. 8 hours) and intravenously administered 1000 mg of melatonin for 11 days. During the course of each day, the patient was intravenously administered 4 saline drips of 500 ml, each containing ten 25 mg bottles of freeze-dried melatonin, lasting 2 hours, totaling 1000 mg per day. No other drug of any kind was administered in order to ascertain the effect of the MLT without interference [...].
