The stress response gene DDR48 has been characterized in Saccharomyces cerevisiae and Candida albicans to be involved in combating various cellular stressors, from oxidative agents to antifungal compounds. Surprisingly, the biological function of DDR48 has yet to be identified, though it is likely an important part of the stress response. To gain insight into its function, we characterized DDR48 in the dimorphic fungal pathogen Histoplasma capsulatum. Transcriptional analyses showed preferential expression of DDR48 in the mycelial phase. Induction of DDR48 in Histoplasma yeasts developed after treatment with various cellular stress compounds. We generated a ddr48∆ deletion mutant to further …

Light And Electron Microscopic Study On The Effect Of Ketoconazole On The Liver Of Adult Male Albino Rats, Bothina L. Mahmoud, Eman S. Ahmad El-Roghy, Maisa A. Kefafy, Rania I. Yassien

Menoufia Medical Journal

Objective The aim of this study was to evaluate the structural, ultrastructural, and biochemical changes in albino rats' liver treated with different doses and durations of ketoconazole and the possible recovery after cessation of treatment. Background Ketoconazole is an imidazole drug commonly used in treatment of fungal infection. It induces variable degree of hepatotoxicity. Materials and methods Fifty adult male albino rats were used in this study. The rats were divided into five groups. Group 1 was the control group. Group II (low dose treated) included 10 rats treated with ketoconazole at a dose of 40 mg/kg body weight orally …

Microsome Biocolloids For Rapid Drug Metabolism And Inhibition Assessment By Lc-Ms, Besnik Bajrami, Sadagopan Krishnan, James F. Rusling

UCHC Articles - Research

Rat liver microsomes attached to nanoparticles were used for LC-MS studies of CYP3A and 2E1 enzymes in metabolism of N-nitroso compounds. Using these biocolloids, turnover rates were measured within 2 min. Inhibitor IC₅₀ values for ketoconazole (KET) and 4-methylpyrazole (4-MEP) were estimated.
