Journal of Lipid Research, 2019 Endogenous synthesis of PUFAs is mediated by genes controlling fatty acid elongases 2 and 5 (ELOVL2 and ELOVL5) and by exogenous DHA intake. Associations between elongases and PUFA levels probably involve genetic variants of ELOVL and changes in DHA ...

Tissue-specific, nutritional, and developmental regulation of rat fatty acid elongases
Journal of Lipid Research, 2005 Of the six fatty acid elongase (Elovl) subtypes expressed in mammals, adult rat liver expresses four subtypes: Elovl-5 > Elovl-1 = Elovl-2 = Elovl-6. Overnight starvation and fish oil-enriched diets repressed hepatic elongase activity in livers of adult ...

The role of iron in normal and impaired testicular function
Andrology, EarlyView.Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Journal of Animal Physiology and Animal Nutrition, EarlyView.ABSTRACT The fatty acid composition of fish is influenced by species, age, diet, and tissues, which respond differently to dietary lipids. This study examined how two commercial diets with contrasting polyunsaturated fatty acid (PUFA) profiles, affecting eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), alter the fatty acid composition in ...

Molecular and functional characterisation of two elovl4 elongases involved in the biosynthesis of very long-chain (>C24) polyunsaturated fatty acids in black seabream Acanthopagrus schlegelii [PDF]
, 2017 Elongation of very long-chain fatty acid (Elovl) 4 proteins are important fatty acyl elongases that participate in the biosynthesis of long-chain (C20-24) and very long-chain (˃C24) polyunsaturated fatty acids (LC-PUFA and VLC-PUFA, respectively) in ...

Journal of Phycology, EarlyView.Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of

Solubilization of C18-Co A and C20-CoA elongases from Allium porrum L. epidermal cell microsomes [PDF]
, 1985 The effects of n-octyl-β-D-glucopyranoside, Triton X-100 and deoxycholate on acyl-CoA elongation by Allium porrum L. epidermal cell microsomes showed that the Triton X-100 specifically stimulated the synthesis of C22–C26 acids using C18-CoA as primer ...

Medical and Veterinary Entomology, EarlyView.The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...
