Importance of Process Parameters Influencing the Mean Diameters of siRNA-Containing Lipid Nanoparticles (LNPs) on the in Vitro Activity of Prepared LNPs
In this study, we used siRNA-containing LNPs as a model, and evaluated the effect that aqueous solution parameters (buffering agent type, salt concentration, and pH) and mixing parameters (ratio, speed, and temperature) exert on the physicochemical properties and in vitro gene-knockdown activity of LNPs. Among such parameters, the type of buffering agent, salt concentration (ionic strength), pH in acidic aqueous buffer, as well as the mixing ratio and speed significantly affected the mean particle diameter and in vitro gene-knockdown activity of LNPs. A strong correlation between the mean particle diameters and their in vi...

Gene knockdown of HCN2 ion channels in the ventral tegmental area reduces ethanol consumption in alcohol preferring rats
CONCLUSION: These results show that knockdown of HCN2 ionic channels in the VTA of UChB rats markedly reduces their voluntary ethanol intake, supporting the idea that HCN2 channels may constitute a therapeutic target for alcohol use disorders.PMID:35377277 | DOI:10.1080/00952990.2022.2033759

Nudix hydrolase NUDT19 regulates mitochondrial function and ATP production in murine hepatocytes
This study is the first to describe Nudt19 as regulator of hepatic lipid metabolism and potential mediator of NAFLD and T2D development.PMID:35367353 | DOI:10.1016/j.bbalip.2022.159153

Valdecoxib attenuates lipid-induced hepatic steatosis through autophagy-mediated suppression of endoplasmic reticulum stress
This study investigated the effects of VAL on lipid accumulation and lipogenesis in human primary hepatocytes. Treatment with VAL suppressed lipid accumulation and expressions of lipogenic genes, such as processed sterol regulatory element binding proteins (SREBP1) and stearoyl-CoA desaturase-1 (SCD1) in palmitate-treated hepatocytes. Furthermore, VAL ameliorated dose-dependently palmitate-induced ER stress markers. Treatment of hepatocytes with VAL increased AMPK phosphorylation and SIRT6 expression. siRNA-mediated suppression of AMPK or SIRT6 abolished the effects of VAL on lipid accumulation, lipogenesis, and endoplasmi...

MEK1/2 inhibitors induce class I alcohol dehydrogenase (ADH1) expression by regulating farnesoid X receptor in hepatic cell lines and C57BL/6J mouse
CONCLUSIONS: Our findings revealed inhibition of ERK1/2 can significantly increase ADH1 expression, indicating MEK1/2 inhibitors may possess potential application in alcohol-related diseases.PMID:35338439 | DOI:10.1007/s11033-022-07361-w
