Targeting the Acute Promyelocytic Leukemia-Associated Fusion Proteins PML/RARα and PLZF/RARα with Interfering Peptides

Figure 3

PCC and POZ influences on the HMW complex formation of PML/RARα and PLZF/RARα, respectively.

A and B, Size-exclusion chromatography fractions of in vitro translated PML/RARα (A) or PLZF/RARα (B) and HA-tagged peptide. Fractions were analyzed by western blot (on the right) and probed against RARα. The densitometric analysis of the western blot is shown on the left side as a percentage of the entire signal. C and D, Size-exclusion chromatography of the Phoenix whole cell lysates overexpressing PML/RARα (C) or PLZF/RARα (D) and GFP-tagged peptide. Fractions were analyzed by western blot (WB) and probed against RARα (α-RARα) (lower part). The densitometric analysis of the western blot is shown in the upper part as a percentage of the entire signal. HA-mock: control empty vector. Input (I), eluted fractions 14 to 29. The numbers above the arrows represent the molecular weight (KD) of the proteins used for the MW calibration: 136 KD for the BSA dimer, 440 KD for Ferritin, and 670 KD for Thyroglobulin.
