Promotion of tumorigenesis by miR-1260b-targeting CASP8: Potential diagnostic and prognostic marker for breast cancer.

ABSTRACT: MicroRNAs are reported as promising biomarkers for the diagnosis and treatment of breast cancer. miR-1260b is identified as a tumor-associated noncoding microRNA in other cancers, although the role of miR-1260b and its clinical relevance in breast cancer remain unclear. In this study, miR-1260b as a potential prognostic biomarker was observed by univariate and multivariate Cox regression analyses in 102 breast tumor tissues. The tumorigenic role of miR-1260b in terms of proliferation, apoptosis, and migration of breast cancer cells was investigated using gain- and loss-of-function assays in vitro. Additionally, the potential early diagnosis and treatment monitoring marker of miR-1260b was validated in 129 plasma samples. We found that high miR-1260b expression was markedly associated with
