Conclusion: These assays are suitable for routine diagnostic. The UltraFast NextGenPCR is the fastest with average time (30mins), followed by Agilent (2 hrs) and MassArray (6hrs). Upon completion of this activity, participants should be able to examine, measure and compare results from different assays for SARS detection, evaluate and diagnose accurately, as well as being able to plan, organize and recommend a diagnostic procedure for diagnostic laboratory. Key words: SARS-CoV-2, RNA extraction, RT-PCR, limit of detection, quantification cycle, COVID-19, in vitro diagnostic tests, Agilent, Massarray, Ultrafast. [20] From t...

Alpha-1 Antitrypsin Deficiency Liver Disease
Liver disease in homozygous ZZ alpha-1 antitrypsin (AAT) deficiency occurs due to the accumulation of large quantities of AAT mutant Z protein polymers in the liver. The mutant Z protein folds improperly during biogenesis and is retained within the hepatocytes rather than appropriately secreted. These intracellular polymers trigger an injury cascade, which leads to liver injury. However, the clinical liver disease is highly variable and not all patients with this same homozygous ZZ genotype develop liver disease. Evidence suggests that genetic determinants of intracellular protein processing, among other unidentified genet...

Metformin protects against ethanol-induced liver triglyceride accumulation by the LKB1/AMPK/ACC pathway
CONCLUSION: Metformin protects against lipid formation in ALD by activating the LKB1/AMPK/ACC axis.PMID:35733070 | DOI:10.1007/s11033-022-07610-y

Upregulation of hepatic CD36 via glucocorticoid receptor activation contributes to dexamethasone-induced liver lipid metabolism disorder in mice
Toxicol Lett. 2022 May 16:S0378-4274(22)00091-1. doi: 10.1016/j.toxlet.2022.05.003. Online ahead of print.ABSTRACTGlucocorticoids such as dexamethasone (DEX) are widely prescribed to treat numerous conditions and diseases. However, glucocorticoid-induced liver lipid metabolism disorder, even nonalcoholic fatty liver disease, has caused extensive attention. Since fatty acid transporters such as CD36 and FATP play crucial roles in hepatic fatty acid uptake, this work examined their potential involvement in DEX-induced liver lipid accumulation. Chronic DEX administration (1-5mg/kg/day over 28 days) induced hepatic lipid accum...

Abietic acid alleviates endoplasmic reticulum stress and lipid accumulation in human primary hepatocytes through the AMPK/ORP150 signaling
This study investigated the impacts of AA on ER stress and steatosis in in vitro obesity models. We found that Treatment with AA reduced lipid deposition and lipogenesis-related proteins expression in human primary hepatocytes. Augmented expression of ER stress markers (phospho-eukaryotic initiation factor-2α (eIF2α) and C/EBP homologous protein (CHOP)) in palmitate-treated hepatocytes were reversed by AA treatment. Further, AA treatment increased the expression of phospho-AMPK and oxygen-regulated protein 150 (ORP150) in hepatocytes. siRNA-associated knockdown of AMPK or ORP150 expression reduced the effects of AA on no...

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...

Harmine suppresses collagen production in hepatic stellate cells by inhibiting DYRK1B
Biochem Biophys Res Commun. 2022 Feb 16;600:136-141. doi: 10.1016/j.bbrc.2022.02.054. Online ahead of print.ABSTRACTLiver fibrosis is a major consequence of chronic liver disease, where excess extracellular matrix is deposited, due caused by the activation of hepatic stellate cells (HSCs). The suppression of collagen production in HSCs is therefore regarded as a therapeutic target of liver fibrosis. The present study investigated effects of harmine, which is a β-carboline alkaloid and known as an inhibitor of dual-specificity tyrosine-regulated kinases (DYRKs), on the production of collagen in HSCs. LX-2 cells, a human HS...

Preparation and Characterization of a Liver Targeted, Poly(amidoamine) Based, Gene Delivery System
Methods Mol Biol. 2022;2455:319-332. doi: 10.1007/978-1-0716-2128-8_24.ABSTRACTNonalcoholic steatohepatitis (NASH) is an aggressive liver disease that is considered a major cause of liver cirrhosis and hepatocellular carcinoma. NASH is characterized by multiple underlying genetic mutations, with no approved cure to date. Gene therapies that target those genetic mutations may play a major role in treating this disease, once delivered specifically to the hepatocytes. In this chapter we present, in detail, the synthesis and the characterization of an efficient gene delivery system capable of targeting hepatocytes by exploitin...
