Phosphatidylcholine Extends Lifespan via DAF-16 and Reduces Amyloid-Beta-Induced Toxicity in Caenorhabditis elegans

Table 5

Effect of daf-16 knockdown on lifespan extension with phosphatidylcholine.

	RNAi	Mean lifespan (day)		value^1
		Control	100 mg/l PC
1st experiment	EV	17.9	21.1	<0.001
	daf-16	15.5	15.6	0.622
2nd experiment	EV	18.5	20.2	0.005
	daf-16	15.7	16.4	0.255

value was calculated using the log-rank test by comparing the survival rate of the untreated control group to that of the phosphatidylcholine-treated group. PC: phosphatidylcholine; EV: empty vector.
