LncRNA MALAT1 as a prognostic biomarker in endometrial cancer: a molecular genetics approach.

ABSTRACT: This study investigates the role of MALAT1 (metastasis-associated lung adenocarcinoma transcript 1) in endometrial cancer, focusing on its expression levels, prognostic significance, and functional impact on tumor biology. RT-qPCR analysis revealed significant upregulation of MALAT1 in endometrial cancer tissues compared to adjacent normal tissues (p < 0.001), with higher expression observed in advanced tumor stages and a correlation with lymphovascular invasion (p < 0.01). Kaplan-Meier survival analysis demonstrated that high MALAT1 expression was associated with shorter overall survival (OS) and progression-free survival (PFS) (log-rank test, p < 0.05). Functional assays indicated that MALAT1 knockdown in Ishikawa and HEC-1A cell lines resulted in decreased cell proliferation, increased
