At the same time, we also found that the expression of USP15 was different in the distribution of breast cancer in different races, including Caucasians (p = 5.12e − 04), African Americans (p = 1.51e − 03), and Asians (p = 5.12e − 04);p = 1.09e − 01). This evidence concerns the gene USP15 and breast carcinoma.
