MAP3K20 and ovarian cancer: To investigate the role of MLK7-AS1 in ovarian cancer cells, MTT assay was performed, and the results showed that cell proliferation was significantly inhibited in the si-MLK7-AS1–1 and si-MLK7-AS1–2 transfected groups compared with that in the si-NC transfected group (Fig. 2b; P < 0.01).
