Expression and transamidation activity of tissue transglutaminase (tTG) may be involved in the morphological modifications leading to the mucosal atrophy observed in coeliac disease (CD). We aimed to investigate the localization of tTG within the duodenal mucosa during the development of villous

Spinal muscular atrophy is due to mutations affecting the SMN1 gene coding for the full-length protein (survival motor neuron; SMN) and the SMN2 gene that preferentially generates an exon 7-deleted protein (SMNΔ7) by alternative splicing. To study SMN and SMNΔ7 degradation in the cell, we have used

Accumulating evidence indicates that neurite degeneration occurs via a distinct mechanism from somal death programs. We have previously shown that neuritic ATP level in sympathetic neurons decreases, whereas somal ATP level remains unaltered during degeneration caused by the microtubule-disrupting

To test the hypothesis that the accumulation of oxidized phospholipids (OxPL) in the macula is toxic to the retina unless neutralized by a variety of mechanisms, including binding by lipoprotein(a) [Lp(a)], which is composed of apolipoprotein(a) [apo(a)] and apolipoprotein B-100 (apoB). Human

N(ε)-(hexanoyl)lysine (HEL) is known to be an oxidative lipid-decomposition product, and a powerful marker indicating oxidative stress in animal tissue. We investigated whether HEL could be useful as a marker in rice seeds damaged by oxidative stress during storage, as well as animals. We could show

Glycation is a series of non-enzymatic reactions initiated by addition of reducing sugars to epsilon-amino group of lysine residues and alpha-amino group of the N terminus of proteins, leading to the formation of advanced glycation end products (AGE). It is thought to be involved in aging and

We recently presented evidence that the subunit eIF3-f of the eukaryotic initiation translation factor eIF3 that interacts with the E3-ligase Atrogin-1/muscle atrophy F-box (MAFbx) for polyubiquitination and proteasome-mediated degradation is a key target that accounts for MAFbx function during

Cartilage degeneration is the hallmark of osteoarthritis (OA) and its early diagnosis is essential for effective cartilage repair. However, until now, there was still a lack of imaging modalities that can accurately detect and evaluate cartilage degeneration in its early stage. Herein, we introduce

BACKGROUND The origin of eukaryotic histone modification enzymes still remains obscure. RESULTS Prototypic KMT4/Dot1 from Archaea targets chromatin proteins (Sul7d and Cren7) and shows increased activity on Sul7d, but not Cren7, in the presence of DNA. CONCLUSIONS Promiscuous aKMT4 could be

Nϵ-carboxymethyl-lysine (CML), an advanced glycation end product, is involved in vascular calcification (VC) in diabetic atherosclerosis. This study aimed to investigate the effects of CML on VC in diabetic atherosclerosis induced by vascular smooth muscle cell (VSMC)-derived foam cells. Human
