Studies on associations of various polymorphisms in xenobiotic metabolizing genes with different cancers including acute lymphoblastic leukaemia (ALL) are mixed and inconclusive. The current study analyzed the relationship between polymorphisms of phase I xenobiotic metabolizing enzymes, cytochromes P450 1A1 (CYP1A1) and CYP2D6 and childhood ALL in Kashmir, India. We recruited 200 confirmed ALL...
objective(s): particularly in developing countries, selenium and/or iodine deficiencies are encountered and use of pesticides in agriculture are not well-controlled. fenvalerate is a pyrethroid insectide used in agriculture and has applications against a wide range of pests. this study was designed to evaluate the effects of fenvalerate on hepatic and cerebral xenobiotic metabolizing enzyme act...
Humans are exposed to numerous xenobiotics, a majority of which are in the form of pharmaceuticals. Apart from human enzymes, recent studies have indicated the role of the gut bacterial community (microbiome) in metabolizing xenobiotics. However, little is known about the contribution of the plethora of gut microbiome in xenobiotic metabolism. The present study reports the results of analyses o...
By discovering how chemical compounds/xenobiotics cytotoxicity is affected when their metabolic pathways are inhibited or activated, the metabolic pathways that activate versus detoxify chemical compound can be identified. Reactive metabolites contributing to cytotoxicity can also be identified. In this lecture, the pretreatment of inhibitors and activators of xenobiotic metabolizing enzymes as...
The correlation between enzyme induction and cell proliferation caused by inducers of xenobiotic metabolizing enzymes was studied using a cell culture expressing a constitutive level of cytochrome P450 (hepatoma McA RH 7777) and a cell culture in which cytochrome P450 was absent (hepatoma 27). In hepatoma 27 cells, the inducers did not induce the synthesis of xenobiotic metabolizing enzymes but...

Germ-free growing rats were fed on a glucosinolate-rich diet (rapeseed-meal-based) and compared with counterparts fed on a glucosinolate-free diet (soya-bean-meal-based), both diets being isonitrogenous and isoenergetic. For each diet half the animals received phenobarbital in drinking water as an inducer of xenobiotic-metabolizing enzymes. Some of the usual deleterious glucosinolate-linked eff...
There are five possible processes of intestinal absorption of xenobiotics. These are active transport, passive diffusions, pinocytosis, filtration through "pores," and lymphatic absorption. The passive diffusion is major process for transport of foreign chemicals across the intestine. Though the lymphatic absorption of drugs is not of any major therapeutic significance, the uptake of toxic chem...
