MSR1 and neoplasm: By analyzing the differential expression of MSR1 in different types of tumor tissues and corresponding normal tissues on the GEPIA (http://gepia.cancer‐pku.cn/detail.php), Oncomine (https://www.oncomine.org/resource/login.html), and TIMER websites, we found that the expression level of MSR1 was higher in most types of tumor tissues than that in corresponding normal tissues (Figure S1A–C).
