Table 1. SkQ1 retards age-dependent increase in heart mass of female BALB/c mice.

Statistical significant p < 0.05 was shown for combined group of old mice receiving 1 or 30 nmol SkQ1/kg per day compared with the control group (2) of old mice.

Group	Age, months	nmol SkQ1/kg per day	Number of animals	Heart mass, mg (M±m)
1	3	-	15	115 ± 3
2	24	-	14	157 ± 9
3	24	1	15	139 ± 4
4	24	30	15	139 ± 4
5	24*	0.05/140	14	146 ± 6

^*Mice received 0.05 nmol SkQ1/kg per day during first 595 days of life and 140 nmol SkQ1/kg per day during the next 130 days.
