The long noncoding RNA TINCR promotes breast cancer cell proliferation and migration by regulating OAS1

Breast cancer is the leading cause of cancer-related death in women around the world. It is urgently needed to identify genes associated with tumorigenesis and prognosis, as well as to elucidate the molecular mechanisms underlying the oncogenic process. Long noncoding RNAs (lncRNAs) are widely invol...

description Breast cancer is the leading cause of cancer-related death in women around the world. It is urgently needed to identify genes associated with tumorigenesis and prognosis, as well as to elucidate the molecular mechanisms underlying the oncogenic process. Long noncoding RNAs (lncRNAs) are widely involved in the pathological and physiological processes of organisms and play an important role as oncogenes or tumor suppressor genes, affecting the development and progression of tumors. In this study, we focused on terminal differentiation-induced non-coding RNA (TINCR) (GeneID:257000) and explore its role in the pathogenesis of breast cancer. The results showed that TINCR was increased in breast cancer tissue, and high expression level of TINCR was associated with older age, larger tumor size, and advanced TNM stage. High level of TINCR can promote proliferation and metastasis of breast cancer cells, while downregulation of TINCR induces G1-G0 arrest and apoptosis. Mechanismly, TINCR can bind to staufen1 (STAU1) and then guide STAU1 (GeneID:6780) to bind to OAS1 mRNA (NM_016816.4) to mediate its stability. Thus low level of OAS1(GeneID:4938) can lead to cell proliferation and migration. This result elucidates a new mechanism for TINCR in breast cancer development and provides a survival indicator and potential therapeutic target for breast cancer patients.
