Gastric cancer molecular and functional approaches in the Brazilian population

Abstract

Gastric cancer is the third leading cause of cancer death worldwide, besides the reduction in its incidence. Late diagnosis usually occurs due to the absence of symptoms or the presence of non-specific symptoms in early stages of the disease. In this case, the available therapeutic options are not efficient, resulting in high morbidity and mortality rates. The continuous study of new strategies for early diagnosis and identification of new therapeutic methods is of great interest in this disease. Our research group has been conducting studies on gastric cancer for over 15 years, in which different chromosomal, gene, protein, and epigenetic alterations have been identified. The purpose of this project is to deepen and extend our previous studies that have shown promising results, as well as, address new technologies for identifying possible biomarkers in gastric cancer. This project involves the analysis of transcriptional and genetic alterations in 8q24.21, validation of epigenetically modulated genes, molecular and phenotypic effects under overexpression and silencing of PCAF, BMP8B, MALAT1 and YWHAE genes in gastric cell lines, inhibition of MELK in cell lines treated with OTSSP167, the miRNoma investigation in gastric tissue samples and circulating signature of miRNAs and the genetic and epigenetic study of the telomere-telomerase complex. This study will allow a better understanding of etiology and physiopathology of gastric carcinogenesis and the identification of possible biomarkers, which may help in early diagnosis, prognosis and anticancer therapies monitoring. Additionally, these possible biomarkers may become targets in the development of new anticancer therapies. (AU)
