Alcohol dehydrogenase gene expression in Chironomus riparius exposed to di(2-ethylhexyl) phthalate.
Di(2-ethylhexyl) phthalate (DEHP) is an industrial additive that is widely used as a plasticizer. Due to its widespread use, DEHP is often found in freshwater ecosystems and many freshwater species have been exposed to various levels of DEHP in natural aquatic systems. Alcohol dehydrogenase (ADH) is a metabolizing enzyme produced in response to exposure to DEHP. To evaluate the effects of DEHP ...
متن کاملAltered cholinesterase and monooxygenase levels in Daphnia magna and Chironomus riparius exposed to environmental pollutants.
Biochemical indices were investigated for their potential use as variables of sublethal toxicity in Daphnia (cholinesterase) and Chironomus (cholinesterase and biotransformation enzymes). Parathion, dichlorvos, and aldicarb caused dose-related inhibition of cholinesterase (ChE) in 24-h bioassays with both species. Ratios of Daphnia and Chironomus ChE IC50 values to corresponding immotility EC50...

لاروهای آبزی پشه‌ی Chironomus riparius Meigen یکی از منابع غذایی غنی در پرورش ماهیان می‌باشد. کمیت و کیفیت ماده‌ی غذایی که در پرورش این لاروها استفاده می‌شود، بر رشد و نمو دوره‌ی لاروی این پشه تأثیر‌گذار است. این مطالعه شامل بررسی اثر جیره‌های غذایی مختلف (کود مرغی، پودر سویا و سبوس برنج) با مقادیر وزنی متفاوت (1، 3 و 5 گرم) بر رشد و نمو لاروها، تعیین زمان مناسب برداشت لاروها در دماهای مختلف (...
متن کاملDifferential Gene-Expression of Metallothionein 1M and 1G in Response to Zinc in Sertoli TM4 Cells
Background: Zinc (Zn) as an important trace element is essential for testicular development and spermatogenesis. Molecular mechanism of Zn action in the reproductive system may be related to metal binding low-molecular weight proteins, metallothioneins (MT). Our objective was to determine the effect of Zn on two important isoforms of MT, MT1M and MT1G genes expression on testicular sertoli cell...
متن کاملEcdysone-Related Biomarkers of Toxicity in the Model Organism Chironomus riparius: Stage and Sex-Dependent Variations in Gene Expression Profiles
Despite being considered a model organism in toxicity studies, particularly in assessing the environmental impact of endocrine disrupting compounds (EDCs) and other chemicals, the molecular basis of development is largely unknown in Chironomus riparius. We have characterized the expression patterns of important genes involved in the ecdysone pathway from embryos to pupa, but specially during th...
