Abstract:
Sarcocornia ambigua is a perennial glasswort, native of South America and a potential new seed-oil crop and forage for direct irrigation with salt water. Small seeds develop inside fertile segments of its cylindrical leafless shoots and, at the harvest, seeds are typically mixed with remnant cellulose material difficult to separate. This work evaluated different extraction methods and the composition of total esterified fatty acids in a meal of ground fertile shoots of S. ambigua, seeking for an alternative primary matter and larger yield of total lipids. The highest lipid yield was obtained w

Abstract:
Colorectal cancer is a heterogenous group of neoplasms showing a variety of clinical and pathological features depending on their anatomical location. Sphingolipids are involved in the formation and progression of cancers, and their changes are an important part of the abnormalities observed during carcinogenesis. Because the course of rectal and colonic cancer differs, the aim of the study was to assess whether the sphingolipid profile is also different in tumors of these two regions.

Diet shapes the gut microbiota which impacts hepatic lipid metabolism. Modifications in liver fat content are associated with metabolic disorders. We investigated the extent of dietary fat and fiber-induced alterations in the composition of gut microbiota and hepatic fatty acids (FAs). Mice were fed a purified low-fat diet (LFD) or high-fat diet (HFD) containing non-soluble fiber cellulose or soluble fiber inulin. HFD induced hepatic decreases in the amounts of C14:0, C16:1n-7, C18:1n-7 and increases in the amounts of C17:0, C20:0, C16:1n-9, C22:5n-3, C20:2n-6, C20:3n-6, and C22:4n-6. When inc

A total of 135 non-redundant proteins interacting with the C2 domains of Syt I were identified.

Abstract:
AbstractCellular RNAs in all three kingdoms of life are modified with diverse chemical modifications. These chemical modifications expand the topological repertoire of RNAs, and fine-tune their functions. Ribosomal RNA in yeast contains more than 100 chemically modified residues in the functionally crucial and evolutionary conserved regions. The chemical modifications in the rRNA are of three types—methylation of the ribose sugars at the C2-positionAbstract (Nm), isomerization of uridines to pseudouridines (Ψ), and base modifications such as (methylation (mN), acetylation (acN), and aminocarboxypropylation (acpN)). The modifications profile of the yeast rRNA has been recently completed, providing an excellent platform to analyze the function of these modifications in RNA metabolism and in cellular physiology. Remarkably, majority of the rRNA modifications and the enzymatic machineries discovered in yeast are highly conserved in eukaryotes including humans. Mutations in factors involved in rRNA modification are linked to several rare severe human diseases (e.g., X-linked Dyskeratosis congenita, the Bowen–Conradi syndrome and the William–Beuren disease). In this chapter, we summarize all rRNA modifications and the corresponding enzymatic machineries of the budding yeast.

Abstract:
Vitamin B5 is the simple acid pantothenic acid (from the Greek pantos, meaning widespread). B5 needs to undergo five enzymatic steps to be converted to coenzyme A, in which the terminal thiol of a cysteamine moiety is the key reactive atom, once dissociated to the thiolate anion. The thiolate serves as nucleophile towards a variety of acids to yield acyl thioesters (acyl-CoAs). These are the cellular acylating agents in metabolic pathways. The two-carbon acyl group in acetyl CoA is doubly activated: as electrophile at C1 and as nucleophile at C2, and so ideally set up for C–C bond formations in fatty acid and steroid biosynthetic pathways, as well as the first step in the citrate metabolic cycle.
