In nanoflow liquid chromatography-matrix-assisted laser desorption/ionization tandem time-of-flight (nanoLC-MALDI-TOF/TOF) approaches, it is critical to directly apply small amounts of the sample elutes on the sample target using a nanoLC system due to its low flow rate of 200 ~ 300 nl/min. It is recommended to apply a sheath liquid containing a matrix with a several μL/min flow rate at the end of the nanoLC column to ensure a larger co-eluted droplet for more reproducible sample spotting and avoid the laborious task of post-manual matrix spotting...

Isofraxidin (IF) is a coumarin compound produced in the functional foods Siberian ginseng and Apium graveolens. The first objective of this study was to investigate the protective effects and putative methods of IF in combating lipotoxicity in vitro and in vivo. Oleic acid was used to induce lipid turbulence in human hepatoma cells (HepG2). Alterations in triglyceride metabolism, inflammation and oxidative status were monitored. Results show that IF mainly reduced triglyceride accumulation, TNF-α release and ROS activation in metabolic disordered cells...

The peroxisomal ATP-binding Cassette (ABC) transporters, which are called ABCD1, ABCD2 and ABCD3, are transmembrane proteins involved in the transport of various lipids that allow their degradation inside the organelle. Defective ABCD1 leads to the accumulation of very long-chain fatty acids and is associated with a complex and severe neurodegenerative disorder called X-linked adrenoleukodystrophy (X-ALD). Although the nucleotide-binding domain is highly conserved and characterized within the ABC transporters family, solid data are missing for the transmembrane domain (TMD) of ABCD proteins...

Postmenopausal diabetic women represent a specific risk group with a greater incidence of vascular deficits as compared with age-matched men or non-diabetic women. 17β-estradiol is the mainstay therapy for menopause and associated complications; however, its vasculoprotective effect is lost in women with diabetes. Although, exact mechanism of dichotomous effect of estrogen has not been delineated but it may be due to, differential activation of ER-α and β during disease conditions such as diabetes. Thus main objective of our study was to characterize the specific estrogen receptor which could be selectively targeted to achieve vasculoprotection in postmenopausal diabetic situation...

Obesity and type 2 diabetes are linked with chronic, low-grade inflammation in visceral adipose tissue (VAT). A unique population of VAT-resident CD4(+)Foxp3(+) Tregs plays a crucial role in regulating VAT inflammation and metabolic homeostasis. VAT-resident Tregs display a highly restricted TCR repertoire, suggesting they recognize certain autoantigen(s) in VAT. A dramatic reduction of VAT-resident Tregs has been shown to closely correlate with obesity-related VAT chronic inflammation and metabolic disorders...

The histidine-rich designer peptide LAH4-L1 exhibits antimicrobial and potent cell-penetrating activities for a wide variety of cargo including nucleic acids, polypeptides, adeno-associated viruses, and nanodots. The non-covalent complexes formed between the peptide and cargo enter the cell via an endosomal pathway where the pH changes from neutral to acidic. Here, we investigated the membrane interactions of the peptide with phospholipid bilayers and its membrane topology using static solid-state NMR spectroscopy...

The aminoglycoside modifying enzyme (AME) ANT(2″)-Ia is a significant target for next generation antibiotic development. Structural studies of a related aminoglycoside-modifying enzyme, ANT(3″)(9), revealed this enzyme contains dynamic, disordered, and well-defined segments that modulate thermodynamically before and after antibiotic binding. Characterizing these structural dynamics is critical for in situ screening, design, and development of contemporary antibiotics that can be implemented in a clinical setting to treat potentially lethal, antibiotic resistant, human infections...

Cardiovascular disease (CVD) represents a global burden with a prevalence that continues increasing progressively. CVD comprises a group of disorders of the heart and blood vessels including coronary heart disease, cerebrovascular disease and peripheral arterial disease. This group of disorders is associated with an inflammatory process which can participate in the pathophysiology of these diseases. Inflammation resolution is an active process involving the participation of pro-resolving mediators such as lipoxins, resolvins, protectins and maresins...

There is a need to develop additional effective therapies for ischemic stroke. Nitrones, which were first developed as reactive oxygen species (ROS)-trapping compounds, have been proposed as neuroprotective agents for ischemic stroke, a ROS-related disorder. The previous reported ROS-trapping compound, quinolyl nitrone RP19, is here being assayed to induce neuroprotection to ischemia-reperfusion injury in three experimental ischemia models: (i), oxygen-glucose deprivation (OGD) on primary neuronal cultures; (ii), transient global cerebral ischemia in four-vessel occlusion model; and (iii), transient focal cerebral ischemia in middle cerebral artery occlusion (tMCAO) model...

Diabetes patients suffer from chronic disorders in the metabolism due to high blood sugar caused by anomalies in insulin excretion. Recently, vanadium compounds have been prepared and functionalized to decrease the level of hyperglycemia. Vitamin A boosts beta cell activity; therefore, the lack of this vitamin plays a role in the development of type 2 diabetes. The aim of this article focused on the synthesis of a new anti-diabetic drug formed from the complexation of a vanadium(IV) salt with vitamin A. Vitamin A acts as a unidentate chelate through the oxygen of its -OH group...

Circadian clock plays an essential role in orchestrating daily physiology, and its disruption can evoke metabolic diseases such as obesity. L-Carnitine can reduce blood lipid levels, and ameliorate fatty liver through regulating lipid metabolism. However, whether L-Carnitine administration may affect the disturbance of lipid metabolism and circadian rhythm of mice induced by prolonged circadian disruption is still unknown. Herein, we investigated the effects of L-Carnitine on conditions of circadian clock and lipid metabolism through a chronic jet-lag mice model which was developed by reversing12 h light/12 h dark cycle every 4 days for a continuous 12 weeks...

Neurofibromatosis type 2 (NF2) is an autosomal dominant disorder characterized by the development of multiple tumors in the central nervous system, most notably schwannomas and meningiomas. Mutational inactivation of the NF2 gene encoding the protein Merlin is found in most sporadic and inherited schwannomas, but the molecular mechanisms underlying neoplastic changes in schwannoma cells remain unclear. We report here that NF2-deficient cells display elevated expression levels of key enzymes involved in lipogenesis and that this upregulation is caused by increased activity of Torc1...

Several inherited metabolic disorders are associated with an accumulation of reactive acyl-CoA metabolites that can non-enzymatically react with lysine residues to modify proteins. While the role of acetylation is well-studied, the pathophysiological relevance of more recently discovered acyl modifications, including those found in inherited metabolic disorders, warrants further investigation. We recently showed that sirtuin 4 (SIRT4) removes glutaryl, 3-hydroxy-3-methylglutaryl, 3-methylglutaryl, and 3-methylglutaconyl modifications from lysine residues...

D Marques-da-Silva, R Francisco, D Webster, V Dos Reis Ferreira, J Jaeken, T Pulinilkunnil
Congenital disorders of glycosylation (CDG) are inborn errors of metabolism due to protein and lipid hypoglycosylation. This rapidly growing family of genetic diseases comprises 103 CDG types, with a broad phenotypic diversity ranging from mild to severe poly-organ -system dysfunction. This literature review summarizes cardiac involvement, reported in 20% of CDG. CDG with cardiac involvement were divided according to the associated type of glycosylation: N-glycosylation, O-glycosylation, dolichol synthesis, glycosylphosphatidylinositol (GPI)-anchor biosynthesis, COG complex, V-ATPase complex, and other glycosylation pathways...
