Induction of Poly(ADP-ribose) Polymerase in Mouse Bone Marrow Stromal Cells Exposed to 900 MHz Radiofrequency Fields: Preliminary Observations

Table 2

Poly(ADP-ribose) polymerase-1 (PARP-1) protein, fold changes relative to housekeeping gene GADPH, in mouse bone marrow cells at different times following exposure to 900 MHz radiofrequency fields (RF), sham (SH), and 1.5 Gy gamma radiation (GR).

Times (h)	RF	SH	GR	values
				RF versus SH	RF versus GR	SH versus GR
0.0				<0.05	<0.05	<0.05
0.5				<0.05	<0.05	<0.05
1.0				<0.05	<0.05	<0.05
2.0				<0.05	<0.05	NS
4.0				<0.05	<0.05	NS
6.0				<0.05	<0.05	NS
8.0				<0.05	<0.05	NS
10.0				<0.05	<0.05	NS

Data are mean ± standard deviation from 3 separate experiments. Significant differences: ; NS: not significant.
