The effect of 5α-DHT (10⁻¹⁰m) and human EGF (0.2 ng/ml) on protein kinase CK2 activity in LNCaP and PC-3 cells

Androgen and EGF treatment lasted 72 h; the control cells were maintained in the absence of these factors as described in “Materials and Methods.”
Cells	Cell fraction	CK2 activity (nmol ³²P/mg protein/h; mean ± SD)
Cells	Cell fraction	Control	5α-DHT	h-EGF^a	5α-DHT + h-EGF
LNCaP	Cytosol	9.7 ± 0.9	5.2 ± 0.4	6.9 ± 0.5	7.2 ± 0.6
	NM	6.0 ± 0.5	9.8 ± 0.8	9.2 ± 0.8	9.4 ± 0.9
PC-3	Cytosol	11.5 ± 0.8	12.3 ± 1.0	8.1 ± 0.7	7.8 ± 0.6
	NM	7.3 ± 0.5	7.0 ± 0.7	10.2 ± 0.9	10.9 ± 0.8
