The protective effects of propolis on biochemical and hematological parameters were appraised in the blood of Oncorhynchus mykiss exposed to cypermethrin (CYP). The fish were subjected to three sublethal concentrations of CYP (0.0041, 0.0082 and 0.0123 ppm) and propolis (10 ppm) for 96 h. The samples were analysed to changes in the biochemical parameters, such as the metabolits: glucose, total ...

Symptom exacerbation due to stress is prevalent in many disease states, including functional disorders of the urinary bladder (e.g., overactive (OAB), interstitial cystitis/bladder pain syndrome (IC/BPS)); however, mechanisms underlying effects on micturition reflex function are unclear. In this study we designed and evaluated a stress-induced symptom (SISE) mouse model that demonstrates increa...

In arthropods, periodic molting plays an important role in the growth, reproduction and morphogenesis. Periodic ecdysis is affected by a variety of environmental own factors, most which controlled concentration steroid hormones, ecdysone (Ecd) whose mainly active form 20-hydroxyecdysone(20E) hormone. Moreover, ecdysteroids play roles regulating development reproduction, CYP302al key enzyme bios...

A unique cytochrome P450 (CYP) oxidoreductase (CPR) sustains activities of human microsomal CYPs. Its function requires toggling between a closed conformation enabling electron transfers from NADPH to FAD and then FMN cofactors open conformations forming complexes transferring electrons We previously demonstrated that distinct features the hinge region linking domain (FD) modulate conformer pos...

Introduction: Cyclophosphamide (CYP) is an alkylating agent, which is used in different diseases. It has several important side effects on ovaries. Tribulus terrestris extract (TTE) has different steroidal saponins and has been used for a long time as an aphrodisiac. The aim of this study was to evaluate the protective effects of TTE on the toxicity of CYP in the ovary of rats. Methods: For...

BACKGROUND Cytochrome P450s (CYPs) are mono-oxygenases that metabolize endogenous compounds, such as fatty acids and lipid signaling molecules, and furthermore have a role in metabolism of xenobiotics. In order to investigate the role of CYP genes in fat metabolism at the molecular level, four Caenorhabditis elegans mutants lacking functional CYP-35A1, CYP-35A2, CYP-35A4, and CYP-35A5 were char...

Hemorrhagic cystitis is a recognizable complication of cyclophosphamide (CYP) attributable to its lively metabolite acrolein, which produces urothelial injury. The study intended examine the uroprotective efficacy total ginsenosides in Chinese ginseng (TGCG) CYP-induced hemorrhagic cystitis. In total, 24 virgin female rats were randomized into four groups as follows: group 1 (control group; inj...

The cytochrome P450 enzyme superfamily (CYP), E.C. 1.14.-.-, are haem-containing monooxygenases with a vast range of both endogenous and exogenous substrates. These include sterols, fatty acids, eicosanoids, fat-soluble vitamins, hormones, pesticides carcinogens as well drugs. Listed below the human enzymes, their relationship rodent CYP activities is obscure in that species orthologue may not ...

Recent studies suggest that cytochrome P450 (CYP) epoxygenase-derived epoxyeicosatrienoic acids (EETs) elicit cell proliferation and promote angiogenesis. The aim of this study was to determine the role of CYP 2C8/9-derived EETs in the process of angiogenesis under hypoxic conditions. In human endothelial cells, hypoxia enhanced the activity of the CYP 2C9 promoter, increased the expression of ...
