Tyrosine 19 phosphorylation has no influence on cell apoptosis. A, The percentage of early apoptotic cells (annexin V+/propidium iodide−) with cytarabine or the negative control (NC) treatment was shown. B,C, Differences in the percentages of early apoptosis cells were compared among Nalm‐6 stable cells overexpressing the empty vector, SRSF1‐WT, or its mutants treated with NS or cytarabine. Column, mean of 3 independent experiments were repeated; bar represents SEM. Each experiment performed in triplicate. *P < .05, **P < .01
