21. Endocrine disruption in fish: sex ratios, secondary sex characters and estrogen-induced proteins
Sammanfattning : .... LÄS MER
22. Molecular mechanisms of AhR mediated endocrine disruption of estrogen and retinoic acid signalling pathways
Sammanfattning : Dioxins and similar compounds are toxic substances ubiquitously present in the environment. The most potent dioxin, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), is considered to be one of the most toxic compounds known to man. LÄS MER
23. Disruption of vitamin A metabolism by dioxin
Sammanfattning : Vitamin A (retinoids) is a nutrient that plays a central role in development and remains essential for cell growth and differentiation throughout life. Dioxins are polychlorinated organic pollutants known to negatively affect the storage and body clearance of retinoids. LÄS MER
24. Pheromonal Mediated Behaviour and Endocrine Responses in Salmonids : The impact of Cypermethrin, Copper, and Glyphosate
Sammanfattning : The effects of cypermethrin, copper and glyphosate on the endocrine system and subsequent response to female pheromones were investigated in mature male brown trout (Salmo trutta) parr. Responses measured were the amount of strippable milt, blood plasma levels of both an androgen (11-ketotestosterone (11-KT)) and a progestin (17α,20β-dihydroxy-4-pregnen-3-one (17,20b-P)), and behavioural changes.

25. Targeted disruption and subcellular distribution of phospholipase C 3
Sammanfattning : Phosphatidylinositol specific phospholipase C (PLC) isoforms are key enzymes in the signal transduction pathway that control many cellular processes including cell proliferation, hormone secretion and egg fertilization. The PLCβ3 gene, assigned to the multiple endocrine neoplasia type 1 (MEN1) locus, has been implicated in endocrine tumorigenesis due to the low expression in several endocrine tumors. LÄS MER
