EXPLORING MITOMIRS IN BREAST CANCER: AN IN-VITRO STUDY OF THEIR EMERGING ROLES

Year 2023, Volume: 86 Issue: 1, 69 - 77, 31.01.2023

Abstract

Objective: Breast cancer is associated with a 5% genetic predisposition in women. Mitochondria play a role in important cellular events such as metabolism, cell death, and inflammation. Recent studies have highlighted precursor micro-RNA (pre-miRNA) to be located in mitochondria as well as mature miRNA. This study aims to reveal the occurrence of mitochondrial miRNA (mitomiR) in breast cancer cells. Materials and Methods: The study has prepared the mitochondrial fractions using the magnetic-activated cell sorting (MACS) method and performed small RNA (sRNA) sequencing. Results: The study has identified known and novel mitomiR sequences aligned to the mitochondrial genome. Conclusion: Identifying new mitomiRs can provide significant contributions and illuminate the molecular mechanism underlying mitomiR biogenesis.

Gereç ve Yöntem: MACS yöntemi kullanılarak mitokondriyal fraksiyonlar hazırlandı ve küçük RNA dizilimi yapıldı. Bulgular: Mitokondriyal genoma hizalanmış bilinen ve yeni mitomiR dizilerini belirledik. Sonuç: Yeni mitomiR’lerin tanımlanması literatüre önemli katkılar sağlayabilir ve mitomiR biyogenezi moleküler mekanizmalar ile aydınlatılabilir.
