We found that MYSM1 mRNA levels were downregulated in ACC (adrenocortical carcinoma), CESC (cervical squamous cell carcinoma and endocervical adenocarcinoma), COAD (colon adenocarcinoma), LUAD (lung adenocarcinoma), LUSC (lung squamous cell carcinoma), OV (ovarian serous cystadenocarcinoma), READ (rectum adenocarcinoma), SKCM (skin cutaneous melanoma), THCA (thyroid carcinoma), UCEC (uterine corpus endometrial carcinoma) and UCS (uterine carcinosarcoma) compared with normal tissues (Figure 1A, Supplementary Figure 1). This evidence concerns the gene MYSM1 and uterine corpus endometrial carcinoma.
