Lipid cascade.
We here review the hypothesis that the toxic effects of ozone are due, at least in part, to a cascade of lipid ozonation products rather than to ozone itself."8 Figure 1 is a cartoon showing the proposed cascade mechanism. The cascade mechanism originated in calculations that suggest that ozone is too reactive to penetrate far into tissue; only ...
This Study Summary was published on April 4 2021. Some evidence suggests that taurine supplementation may increase lipid metabolism during high-intensity exercise, potentially resu...It works through the β2 adrenergic receptor to elicit the cAMP signaling cascade (Tymoczko3e Fig 13.4; Berg8e Fig. 14.1). The image below is of the hormone-bound, activated form of the β2 adrenergic receptor. The red and blue lines demarcate the boundaries of the outer and inner leaflets of the lipid bilayer, respectively.A large and diverse array of chemoattractants control leukocyte trafficking, but how these apparently redundant signals collaborate in vivo is still largely unknown. We previously demonstrated an absolute requirement for the lipid chemoattractant leukotriene B 4 (LTB 4) and its receptor BLT1 for neutrophil recruitment into the joint in autoantibody-induced arthritis.The present study for the first time aims to examine the hypothesis that circulating gamma-glutamyl carboxylated growth arrest specific protein 6 (Gla-Gas6) deficiency may be associated with hyperlipidemia and vitamin K (VK) supplementation may ameliorate the impaired lipid homeostasis via activating Gas6 protein.Lipid peroxidation, or lipid oxidation, is a complex chemical process that leads to oxidative degradation of lipids, resulting in the formation of peroxide and hydroperoxide derivatives. It occurs when free radicals, specifically reactive oxygen species (ROS), interact with lipids within cell membranes, typically polyunsaturated fatty acids (PUFAs) as they have …
This effect was fully abrogated after RARα knockdown, suggesting Alisol B suppressed CD36 via regulating RARα-HNF4α-PPARγ cascade. Moreover, the hepatic gene expression of RARα was obviously decreased in murine NASH models, whereas Alisol B significantly increased RARα expression and decreased CD36 expression, along with the ...
