Gene expression in neonatal Atf4 KO mice as compared to wild-type littermates

	BiP	Chop	Xbp1-s	Reg2	Pap	Mac-2
Fold difference	0.84, n.s.	0.71, n.s.	0.83, n.s.	0.08*	4.93**	1.01, n.s.

n.s.= not significant

*P = 0.01

**P = 0.03

The ratios of KO to WT expression levels for P6-15 are shown. Statistically significant expression differences were determined by Student's t-test. The levels of all genes were normalized to a-tubulin, except Xbp1-s, which was normalized to Xbp1-t. For WT n = 6 and for KO n = 5.
