Benzo[a]pyrene (BaP) is a human carcinogen that covalently binds to DNA after metabolic activation by cytochrome P450 (CYP) enzymes. In this study human recombinant CYPs (CYP1A1, 1A2, 1B1, 2A6, 2B6, 2C8, 2C9, 2C19, 2E1, 3A4, and 3A5) were expressed in Supersomes™ together with their reductases, NADPH:CYP oxidoreductase, epoxide hydrolase and cytochrome b5 , to investigate BaP metabolism. Human ...

Alzheimer’s disease (AD) is a multifactorial disease in which b-amyloid peptide (bAP) plays a critical role. We report here that the soluble fraction 1–40 of bAP differentially degrades protein kinase C-a and -g (PKCa and PKCg) isoenzymes in normal (age-matched controls, AC) and AD fibroblasts most likely through proteolytic cascades. Treatment with nanomolar concentrations of bAP(1–40) induced...

In this study, it was aimed to determine the total antioxidant capacity and phenolic flavonoid amounts of Lavandula officinalis (lavender), which is an aromatic plant, callus extracts. Combinations Naphthalene Acetic Acid (NAA), Benzylaminopurine (BAP), Kinetin (KIN) 2,4-Dichlorophenoxy (2,4-D) plant growth regulators at different concentrations were used in medium. The specified analyzes carri...

In vitro propagation of rose (Rosa indica) as well as rose breeding is a valuable economic enterprise and has received highest importance globally including Indian subcontinent. The development of new cultivars for commerce is faced with new challenges. In vitro micropropagation protocols of varieties of roses have been established but very few reports on the clonal propagation of local cultiva...

The loss of striatal dopamine (DA) in Parkinson's disease (PD) models triggers a cell-type-specific reduction in the density of dendritic spines in D(2) receptor-expressing striatopallidal medium spiny neurons (D(2) MSNs). How the intrinsic properties of MSN dendrites, where the vast majority of DA receptors are found, contribute to this adaptation is not clear. To address this question, two-ph...

Polycyclic aromatic hydrocarbons (PAH), like Benzo[alpha]Pyrene (BaP) are known to cause a number of toxic manifestations including lung cancer. As Titanium dioxide Nanoparticles (TiO2 NPs) have recently been shown to adsorb a number of PAHs from soil and water, we investigated whether TiO2 NPs could provide protection against the BaP induced toxicity in biological system. A549 cells when co-ex...

Cellulosimicrobium cellulans CWS2, a novel strain capable of utilizing benzo(a)pyrene (BaP) as the sole carbon and energy source under nitrate-reducing conditions, was isolated from PAH-contaminated soil. Temperature and pH significantly affected BaP biodegradation, and the strain exhibited enhanced biodegradation ability at temperatures above 30°C and between pH 7 and 10. The highest BaP remov...

Abstract Calotropis gigantea is a plant not widely used but has potential as medicinal plant. The phytochemical compound can be produced faster using tissue culture and combination of growth regulators. research objectives were to study the effect determine best concentration BAP 2,4-D in callus induction . This was carried out Plant Physiology Biotechnology Laboratory, Faculty Agriculture, Seb...
