The aim of this study was to explore the impacts of heat stress (HS) on expressions of selenoprotein genes in IPEC-J2 cells. Cells were cultured with 5 % CO2-humidified chamber at 37 °C until the cells grew to complete confluence and then exposed to a mild hyperthermia at 41.5 °C (HS) or 37 °C (control) for another 24 h, finally harvested for total RNA or(More)
The purpose of this study was to compare messenger RNA (mRNA) expression of selenoprotein genes between hepatoma HepG2 and normal hepatocytes LO2 cell lines. Liver HepG2 and LO2 cells were cultured in 12-well plates under the same condition until cells grew to complete confluence, and then cells were harvested for total RNA and protein extraction. The qPCRs(More)
Pancreatic lipase plays a key role in intestinal digestion of feed fat, and is often deficient in young animals such as weaning piglets. The objective of this study was to express and characterize a partial codon optimized porcine pancreatic lipase (opPPL). A 537 bp cDNA fragment encoding N-terminus amino acid residue of the mature porcine pancreatic lipase(More)
To determine the roles of selenoprotein X gene (Selx) in protecting liver cells against oxidative damage, the influences of Selx knockdown on H2O2-induced apoptosis in human normal hepatocyte (LO2) cells were studied. pSilencer 3.1 was used to develop knockdown vector targeting the 3′-UTR of human Selx. The Selx knockdown and control cells were further(More)
Key-value data store has been widely used in e-commerce systems. The availability issue, which means no data loss and continuous service to users, is quite essential in such systems. This paper presents a lightweight, highly available architecture of key-value data store. This architecture uses a Paxos-based replication protocol to make synchronous(More)
