Additional file 1: of Meclofenamic acid represses spermatogonial proliferation through modulating m6A RNA modification HuangTao GuoJiayin LvYinghua ZhengYi FengTongying GaoQiang ZengWenxian 2019 Figure S1. Detection of m6Am level in polyA RNA and small nuclear RNA. Cells were treated with 0, 40, 80 and 120 μmol/L MA2. Content of m6Am and A was detected by LC/MS-MS. Relative m6Am level was normalized by m6Am/A. (A) Relative m6Am level of PolyA RNA. Data were represented by the mean ± SEM, n = 3. n,s means P > 0.05. (B) Relative m6Am level of snRNA. Data were represented by the mean ± SEM, n = 3. (JPG 648 kb)
