Abstract
Breast cancer is one of the most common malignancies in women worldwide. Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are the most common kinds of invasive breast cancer. Several genetic, epigenetic, and environmental factors could trigger the pathogenesis of breast cancer. Breast cancer treatment generally includes surgery, radiation therapy, chemotherapy, hormonal treatment, targeted therapy, immunotherapeutic, neoadjuvant systemic therapy, and systemic therapy. Although several classical treatment methods are used in cancer therapy, molecular-based strategies can open a new perspective for breast cancer treatment. Previous studies reported that long non-coding RNAs (lncRNAs) play important roles in cancer development and progression. LncRNA TUG1 was found to target several miRNAs and regulate breast cancer cell behavior. TUG1 can induce cell proliferation and invasion of breast cancer cells via downregulation of some miRNAs. Therefore, TUG1 might be a potent biomarker for the treatment of human cancer. In this review, we summarized the functional roles of TUG1 in breast cancer.
