Two-way ANOVA P values

Protein	Treatment	Time	Interaction (treatment × time)
VEGF	P < 0.0001	P < 0.0001	P < 0.0001
HO-1	P < 0.0001	P < 0.005	P < 0.0001
Hsp70	P < 0.0001	P < 0.0001	P < 0.0001
Egr-1	P < 0.0001	P < 0.0001	P < 0.0001

Normalized protein values (VEGF, Hsp70, HO-1 Egr-1; AU) were analyzed using two-way analysis of variance (SPSS Program Version 13.0, SPSS, Inc., Chicago, IL, USA). A probability level of P < 0.05 was considered as significant. As indicated by P values both factors (treatment, time) as well as their interaction. (treatment × time) influenced significantly the expression of all the proteins analyzed
