Activities of ADPR cyclase, cADPR hydrolase, and NADase in extracts from uteri of control and E₂-treated rats

	Control	E2 treated	Δ,* %
ADPR cyclase (nmol cADPR/mg protein per 60 min)	1.5  ±  0.1	6.5  ±  0.5†	+330
cADPR hydrolase (nmol ADPR/mg protein per 60 min)	3.0  ±  0.05	7.5  ±  0.1†	+150
NADase (Δ fluorescence per min)	1.2  ±  0.1	2.18  ±  0.2†	+81

Values denote mean ± SEM from four experiments. 

^*Denotes relative percent difference between E₂ treated and controls. 

^†E₂-treated value significantly (P < 0.01, t test) higher than controls. 

^‡Increment in ADPR cyclase activity from E₂-treated compared with control is significantly (P < 0.01, t test) higher than increments of cADPR hydrolase and NADase activities.
