TABLE 2.

Apparent rate constants of NO accumulation upon Sp/NO (50 μm) decomposition in the presence of cells with different levels of cytoglobin hCYGB, human CYGB.

	Initial rate (±S.E.)	Second rate (±S.E.)
	nm·s–1	nm·s–1
Buffer alone	4.9 ± 0.3
shScrambled	2.1 ± 0.1a,b	1.0 ± 0.1
shCYGB	2.8 ± 0.1a,c	1.4 ± 0.1c
shCYGB + hCYGB	2.2 ± 0.2a,b	1.3 ± 0.1c

^aIndicates p < 0.001 as compared with buffer

^bIndicates p < 0.05 as compared with shCYGB

^cIndicates p < 0.05 as compared with shScrambled
