Breast cancer is the leading cause of cancer death in women worldwide. Long non-coding RNA small nucleolar RNA host gene 1 (SNHG1) has been reported to be involved in human diseases, including cancer. Here, we found that SNHG1 expression was significantly upregulated in human breast cancer tissues and cell lines. We explored the function of SNHG1 in breast cancer cells using in vitro and in vivo experiments and found that SNHG1 promotes breast cancer metastasis and proliferation. The potential molecular mechanism of SNHG1 in breast cancer cells may involve SNHG1 acting as a sponge of miR-193a-5p to activate the expression of the oncogene HOXA1. In summary, our study reveals a novel SNHG1/miR-193a-5p/HOXA1 competing endogenous RNA regulatory pathway in breast cancer progression and may provide new strategies for breast cancer therapy.
