uroporphyrin/zea mays

Glutathione S-transferases (GSTs) are multi-functional enzymes, known to conjugate xenobiotics and degrade peroxides. Herein, we report on the potential of four Zea mays GST isoforms (Zm GST I-I, Zm GST I-II, Zm GST II-II and Zm GST III-III) to act as binding and protection proteins. These isoforms

Hexachlorobenzene (HCB) induces hepatic porphyria in rats. Various protocols of repeated cumulative and daily doses of HCB administered for several weeks until porphyria develops have been traditionally used. In order to undertake studies on early biochemical events occurring in HCB-induced

Hexachlorobenzene (HCB) is porphyrinogenic in adult female but not in male rats. This study aimed to assess the role of 17beta-estradiol in the induction of porphyria by HCB in both sexes by adding or removing the hormone. Groups of intact females, ovariectomized females (Ova), castrated males
