Tissue CBS activity in normal versus Snell dwarf mice.^a

Organ	Normal	Dwarf	n	p
Liver	110 ± 4	108 ± 4	8	> 0.6
Brain	7.3 ± 0.2	10.0 ± 0.4	8	< 0.0001
b Kidney(total)	36 ± 4	52±3	8	< 0.0002
Kidney (male)	47±4	57±4	4	>0.08
Kidney (female)	27±3	48±2	4	<0.001

^aData represent the mean ± SEM values in units of mmol h⁻¹ kg tissue⁻¹. n indicates the number of animals, p indicates statistical significance. Liver and brain groups contained equal number of males and females.

^bCBS activity in normal male and female kidney is significantly different (p<0.006); the difference in CBS activity in dwarf males and female kidney shows borderline significance (p=0.048); CBS activity in normal male and dwarf female kidney is not significantly different (p>0.8).
