MicroRNA (miRNA/miR) miR526b and miR655 overexpressed tumor cell-free secretions promote breast cancer phenotypes in the tumor microenvironment (TME). However, the mechanisms of miRNA regulating TME have never been investigated. With mass spectrometry analysis of MCF7-miRNA-overexpressed versus miRN...

The Effects of miR-526b, miR655 and COX-2 Overexpression on Oxidative and Genotoxic Stress in MCF7 Breast Cancer Cells
Breast cancer progression and therapeutic resistance are influenced by the tumor’s ability to adapt to cellular stress, including oxidative damage and chemotherapeutic pressure. Two microRNAs, miR-526b and miR-655, have been shown to promote aggressive breast cancer phenotypes, such as enhanced prol...
