21775771-5	2011	Prenatal nicotine increased active MMP-2 forms and interstitial collagen but had no effect on either pro- or active MMP-9 or MMP-13 forms.	Nicotine	9-17	72 kDa type IV collagenase	Cavia porcellus	35-40	
21775771-6	2011	In the presence of nicotine, NAC decreased active MMP-2 protein levels and reversed the nicotine-induced increase in collagen staining.	Nicotine	19-27	72 kDa type IV collagenase	Cavia porcellus	50-55	
21775771-7	2011	We conclude that prenatal nicotine alters MMP-2 expression in fetal hearts that may be mediated by reactive oxygen species generation.	Nicotine	26-34	72 kDa type IV collagenase	Cavia porcellus	42-47
