PHF6 modulates Notch1 expression and its downstream signaling activity. (A) (left) Flow cytometry analysis of control and PHF6 shRNA transduced CD34+ thymocytes in OP9-DLL1 cocultures in the presence of IL7, SCF and FLT3L, showing the development of CD4+CD8β+ DP thymocytes after 21 days of coculture. (right) Bar plot showing the frequency of CD4+CD8β+ DP thymocytes, generated in the corresponding cultures. Data shows the average of 4 independent experiments and errors bars show SEM. *P < 0.05 (paired t-test) (B) Normalized NOTCH1 and DTX1 expression in Jurkat cells (left) and CB-derived CD34+ HPCs (right) following control or PHF6 shRNA transduction as indicated. Data shows the average expression in 3 independent samples and error bars indicate SEM.
