Structural bases for the Charcot-Marie-Tooth disease induced by single amino acid substitutions of myelin protein zero

Myelin protein zero (MPZ or P0) is a transmembrane protein which functions to glue membranes in peripheral myelin. Inter-membrane adhesion is mediated by homophilic interactions between the extracellular domains (ECDs) of MPZ.

Abnormal lactate metabolism is linked to albuminuria and kidney injury in diabetic nephropathy

Diabetic nephropathy (DN) is characterized by abnormal kidney energy metabolism, but its causes and contributions to DN pathogenesis are not clear. To examine this issue, we carried out targeted metabolomics profiling in a mouse model of DN that develops kidney disease resembling the human disorder.

GAS41 promotes H2A.Z deposition through recognition of the N terminus of histone H3 by the YEATS domain

Glioma amplified sequence 41 (GAS41), which has the Yaf9, ENL, AF9, Taf14, and Sas5 (YEATS) domain that recognizes lysine acetylation (Kac), regulates gene expression as a subunit of the SRCAP (SNF2-related CREBBP activator protein) complex that deposits histone H2A.Z at promoters in eukaryotes. The YEATS domains of the proteins AF9 and ENL recognize Kac by hydrogen bonding the aromatic cage to arginine situated just before K9ac or K27ac in the N-terminal tail of histone H3. Curiously,

Angiotensin II type 1 receptor-associated protein in immune cells: a possible key factor in the pathogenesis of visceral obesity

Background and aim Dysregulation of angiotensin II type 1 receptor-associated protein (ATRAP) expression in cardiovascular, kidney, and adipose tissues is involved in the pathology of hypertension, cardiac hypertrophy, atherosclerosis, kidney injury, and metabolic disorders. Furthermore, ATRAP is highly expressed in bone marrow-derived immune cells; however, the functional role of immune cell ATRAP in obesity-related pathology remains unclear. Thus, we sought to identify the pathophysiological significance of immune cell ATRAP in the development of visceral obesity and obesity-related metabolic disorders using a mouse model of diet-induced obesity.
