Furan is produced in a wide variety of heat-treated foods via thermal degradation. Furan contamination is found to be relatively high in processed baby foods, cereal products, fruits juices, and canned vegetables. Several studies have demonstrated that furan is a potent hepatotoxin and hepatocarcinogen in rodents. However, few studies have investigated the toxic effects of furan in the testis. In addition, the exact mechanism(s) by which furan exerts toxicity in the testis has not been fully …show more content…

Our findings revealed that GO significantly down-regulates the overexpression of
CYP2E1. This finding is consistent with several previous studies that reported that certain garlic ingredients are selective competitive inhibitors of CYP2E1 (Premdas et al., 2000; Wargovich, 2006; Zeng et al., 2009; Zhang et al., 2013). The garlic ingredient, diallyl sulphide, inhibits CYP2E1-dependant transformation of acrylamide into its end toxic product glycidamide (Taubert et al., 2006). Furthermore,
CYP2E1 knock-out mice led to a dramatic inhibition of acrylamide conversion to glycidamide and an absence in acrylamide-induced toxicity
(Ghanayem et al., 2005a,b). Therefore, in addition to the antioxidant capability of GO, it is plausible to conclude that selective blockade of the CYP2E1 pathway by garlic oil is likely to be one of the underlying mechanisms underpinning the suppression of furan-induced oxidative stress.
In the present study, a significant reduction in testosterone levels was found in the furan-treated group. The reduction in the levels of testosterone is consistent with previous studies (Karacaoglu and Selmanoglu,
2010). However, our results contradict Cooke et al. …show more content…
