Abstract
The development of in vitro models that recapitulate critical liver functions is essential for accurate assessments of drug toxicity. Although liver organoids can be used for drug discovery and toxicology, they are limited by (i) the lack of expression and activity of xenobiotic-metabolizing enzymes, and (ii) the difficulty of mimicking non-alcoholic fatty liver disease (NAFLD, which influences the expression of these enzymes) in vitro. Here, we generated three-dimensional multi-cell-type liver organoids (hereafter "HML organoids") from HepaRG cells, primary human macrophages, and hepatic-stellate-cell-derived LX-2 cells. We also developed an NAFLD model by culturing HML organoids for 9 days with a mixture of stearic and oleic acids. The exposed organoids showed typical features of steatosis and expressed fibrosis markers. We subsequently used HML and NAFLD-HML organoids to model drug-induced liver injury. By estimating the IC50 and benchmark doses, we were able to improve the in vitro detection of drugs likely to be toxic in fatty livers. Thus, HML and NAFLD-HML organoids exhibited most of the liver's functions and are relevant in vitro models of drug metabolism, drug toxicity, and adverse drug event in NAFLD.

Abstract
The intake of the essential fatty acid precursor α-linolenic acid (ALA) contributes to ensure adequate n-3 long-chain polyunsaturated fatty acid (LC-PUFA) bioavailability. Conversely, linoleic acid (LA) intake may compromise tissue n-3 PUFA status as its conversion to n-6 LC-PUFA shares a common enzymatic pathway with the n-3 family. This study aimed to measure dietary ALA and LA contribution to LC-PUFA biosynthesis and tissue composition. Rats were fed with control or experimental diets moderately enriched in ALA or LA for 8 weeks. Liver Δ6- and Δ5-desaturases were analyzed and FA composition was determined in tissues (red blood cells, liver, brain and heart). Hepatic Δ6-desaturase activity was activated with both diets, and Δ5-desaturase activity only with the ALA diet. The ALA diet led to higher n-3 LC-PUFA composition, including DHA in brain and heart. The LA diet reduced n-3 content in blood, liver and heart, without impacting n-6 LC-PUFA composition. At levels relevant with human nutrition, increasing dietary ALA and reducing LA intake were both beneficial in increasing n-3 LC-PUFA bioavailability in tissues.

Abstract
A single gene encoding a δ6-desaturase (FADS2) has been isolated and characterized in mammalian species. This δ6-desaturase plays a major role in the biosynthesis of PUFAs (polyunsaturated fatty acids). It catalyses the rate-limiting desaturation of linoleic acid (C18:2n−6) and α-linolenic acid (C18:3n−3) required for the biosynthesis of long-chain PUFAs. Moreover, recent studies have provided strong evidence that this δ6-desaturase also acts on 24-carbon PUFAs of both the n−6 and n−3 series. Another substrate of this δ6-desaturase has been identified through complementary works from different investigators. This δ6-desaturase acts on a saturated fatty acid, palmitic acid (C16:0), leading to the newly characterized biosynthesis of hexadecenoic acid (C16:1n−10) or sapienate.

Abstract
Heparan sulfate proteoglycans are found on the surface of most cells. Syndecan-4 is a widely expressed transmembrane heparan sulfate proteoglycan. Using quantitative RNase protection assays and immunoblotting, syndecan-4 expression was characterized in 3T3-F442A mouse adipoblasts. These cells exhibit dramatic changes in their biological and morphological characteristics during differentiation to adipocytes. During this process, the levels of syndecan-4 protein and mRNA expression changed dramatically. They peaked at the time when quiescent cells reentered the cell cycle before differentiation. Serum depletion-repletion also replicated the syndecan-4 mRNA induction when the cells were released back into proliferation, and a cycloheximide treatment abolished the peak of induction. In addition, inhibiting syndecan-4 induction with antisense oligonucleotides inhibited the proliferation of 3T3-F442A cells. In the terminally differentiated adipocytes characterized by the loss of proliferation capability, the serum inducibility of syndecan-4 is repressed, emphasizing the link between syndecan-4 induction in 3T3-F442A cells and cell proliferation.

Abstract
This study was designed to examine and compare the metabolism of myristic and palmitic acids in cultured rat hepatocytes. [1-(14)C]-Labeled fatty acids were solubilized with albumin at 0.1 mmol/L in culture medium. Incubation with 24-hr cultured hepatocytes was carried out for 12 hr. Myristic acid was more rapidly (P < 0.05) taken up by the cells than was palmitic acid (86.9 +/- 0.9% and 68.3 +/- 5.7%, respectively, of the initial radioactivity was cleared from the medium after 4 hr incubation). Incorporation into cellular lipids, however, was similar after the same time (33.4 +/- 2.8% and 34.9 +/- 9.3%, respectively, of initial radioactivity). In the early phase of the incubation (30 min), myristic acid was more rapidly incorporated into cellular triglycerides than was palmitic acid (7.4 +/- 0.9% and 3.6 +/- 1.9%, respectively, of initial radioactivity). However, after 12 hr incubation, the radioactivity of cellular triglycerides, cellular phospholipids, and secreted triglycerides was significantly higher with palmitic acid as precursor. Myristic acid oxidation was significantly higher than that of palmitic acid (14.9 +/- 2.2% and 2.3 +/- 0.6%, respectively, of the initial radioactivity was incorporated into the beta-oxidation products after 4 hr). Myristic acid was also more strongly elongated to radiolabeled palmitic acid (12.2 +/- 0.8% of initial radioactivity after 12 hr) than palmitic acid was to stearic acid (5.1 +/- 1.3% of initial radioactivity after 12 hr). The combination of elongation and beta-oxidation results in the rapid disappearance of C14:0 in hepatocytes whereas C16:0 is esterified to form glycerolipids. This study provides evidence that myristic acid is more rapidly metabolized in cultured hepatocytes than is palmitic acid.

Abstract
Protein contents of venom-producing glands from the sea-snake Laticauda colubrina (LC) and terrestrial Vipera Russelli (VR) were studied using high-resolution two-dimensional gels: isoelectric focusing followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (IEF/SDS-PAGE) and nonequilibrium pH gradient electrophoresis (NEPHGE) followed by SDS-PAGE. Tentative identities of numerous proteins were established using their amino acid compositions and in certain cases the identities were verified by microsequencing of their N-terminals and internal fragments. As expected, we found several proteins known to be present in the venom of the respective snakes. These include numerous isoforms of phospholipase A2 (PLA2) in both snake glands, various neurotoxins in LC glands and factor IX/factor X-binding protein, hemorrhagic factor and coagulation factor X activating enzyme in Russell's viper glands (VR). Not unexpectedly, we also found a number of cell housekeeping proteins, cytoskeletal proteins, proteins that are necessary for folding, such as heat-shock proteins, protein disulfide-isomerase and peptidyl-prolyl cis/trans isomerases. Unexpectedly, however, the glands of Laticauda colubrina and Russell's viper include a large quantity of antihemorrhagic factor and inhibitor of PLA2, respectively, that have been previously described in snake plasma. The possible reason associated with the presence of these components in venom glands is discussed.

Abstract
The amino acid composition (AAC) versus the protein identity (PI) method was used for establishment of the identities of proteins from bovine brain and kidneys which were prefractionated on a CM52 cation exchanger and by preparative flat-bed isoelectric focusing. Established identities of proteins whose AACs converge with those of other members of their proper superfamily are reliable. Groups of convergent AACs can be extracted from protein databases using the standard root-mean-square rule (Rmsd) with measures the difference between the AAC of chosen protein versus those in the database. Convergence of AACs of proteins is dependent on several factors such as the upper limit of Rmsd, the limits of variations of molecular mass (m) and isoelectric point (pI), the number of proteins with similar AACs present in protein databases, and the domain structure of proteins. AACs of many proteins remain unique if the Rmsd is maintained within 1.5-1.0 with m +/- 3kDA and pI +/- 4. Certain groups of multidomain proteins have quasi-unique AACs only if the Rmsd is restrained to a value within 1.0 and 0.7. Convergence of AACs of certain groups of proteins may indicate that a common biological function exists for some members of each group. The AAC-PI method may become an additional search tool for protein functions.
