The expression of MORT and miRNA-16 was positively correlated only in MCL patients.Results: Overexpression of MORT and miRNA-16 suppressed Potato Masher cell proliferation but promoted cancer cell apoptosis, while miRNA-16 inhibitor reduced the effects of MORT overexpression.Overexpression of MORT led to upregulated expression of miRNA-16, while overexpression of miRNA-16 had no effect on the expression of MORT.Conclusion: Therefore, MORT may inhibit cancer cell proliferation and promote apoptosis in mantle cell lymphoma by upregulating miRNA-16.Keywords: mantle cell lymphoma, MORT, miRNA-16, prognosis, cancer cell.
