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. This evidence concerns the gene SNHG1 and breast cancer.
