Alpha 1-antitrypsin mitigates salt-sensitive hypertension in juvenile mice by reducing diacylglycerol concentrations and protein kinase C activity in kidney membranes by Yunus E. Dogan, Yunus E. Dogan, Yunus E. Dogan, Niharika Bala, Niharika Bala, Erika S. Galban, Erika S. Galban, Russell L. Lewis, Nancy D. Denslow, Sihong Song, Abdel A. Alli, Abdel A. Alli

“…Here, we hypothesized that administration of pharmaceutical-grade human AAT (hAAT) is effective in mitigating hypertension induced by salt-loading in juvenile mice by reducing the concentration of diacylglycerols (DAGs) and activity of protein kinase C (PKC) in the kidney.MethodsFour-week old 129Sv mice were salt-loaded to induce hypertension and then administered hAAT or vehicle.ResultsAdministration of hAAT was found to significantly reduce high blood pressure in both the active and inactive cycles of the 129Sv hypertensive mice. A lipidomic analysis showed decreased concentrations of multiple diacylglycerols in kidney cortex membrane fractions from mice treated with hAAT compared to vehicle. …”

A novel protein encoded by porcine circANKRD17 activates the PPAR pathway to regulate intramuscular fat metabolism by Xiao He, Fang Xie, Ying Nie, Xuefeng Wang, Junyi Luo, Ting Chen, Qianyun Xi, Yongliang Zhang, Jiajie Sun

“…These genes included FABP4, FABP5, CPT1A, and UBC, consistent with the high levels of acylcarnitines observed in the longissimus dorsi muscles of the Lantang breed, as determined by lipidomic analysis. Further in vitro and in vivo experiments indicated that circANKRD17 can regulate lipid metabolism through various mechanisms involving the PPAR pathway, including promoting adipocyte differentiation, fatty acid transport and metabolism, triglyceride synthesis, and lipid droplet formation and maturation. …”

Genetic and biochemical analysis of severe hypertriglyceridemia complicated with acute pancreatitis or with low post-heparin lipoprotein lipase mass by Takashi Suzuki, Makoto Kurano, Akari Isono, Takuya Uchino, Yohei Sayama, Honami Tomomitsu, Daiki Mayumi, Ruriko Shibayama, Toru Sekiguchi, Naoki Edo, Kiyoko Uno-Eder, Kenji Uno, Koji Morita, Toshio Ishikawa, Kazuhisa Tsukamoto

“…ELISA and Western blot analysis of the serum revealed the existence of apolipoprotein A-V in the lipoprotein-free fraction regardless of the presence or absence of rs2075291; furthermore, the molecular weight of apolipoprotein A-V was different depending on the class of lipoprotein or lipoprotein-free fraction. Lipidomics analysis showed increased serum levels of sphingomyelin and many classes of glycerophospholipid; however, when individual patients were compared, the degree of increase in each class of phospholipid among cases did not coincide with the increases seen in total cholesterol and triglycerides. …”
