Fig. 4.

Protein expression profiles of PC KD and SC MDA-MB-231 cells, and their potential interaction with PC, apoptotic and cell cycle regulators. A) Protein expression profiles in SC (columns 1–4), PC KD 4B#3 (columns 5–8) and 4B#4 (columns 9–12) cells from days 1–4, respectively. Green, black and red colors represent low, moderate and high levels of expression, respectively. B) Numbers of proteins expressed in PC KD 4B#3 and 4B#4 and SC cells. C) STITCH 5.0 analysis indicates the association of candidate proteins whose expression levels are correlated with the degree of apoptosis and G2/M arrest.
