Popis: | Peroxisomes, also termed as microbodies, are now known to carry out several specialized metabolic activities that are vital to cellular function. A defect in peroxisomal function leads to development of a fatal human disease, and a number of peroxisomal disorders are now linked to inherited peroxisomal enzyme abnormalities. Peroxisomal enzyme activities are also altered during pathophysiological conditions through various endogenously produced bio-molecules such as nitric oxide (NO). NO produced by cytokines or NO-donors is known to modulate peroxisomal functions, and these effects of NO are mediated through cGMP. We are reporting for the first time that L-carnitine (1–5 mm) prevents cGMP-mediated impairment of peroxisomal enzyme activities. Cyclic GMP (250–1000 μM) significantly inhibited (p |
