.... These include ATP-sensitive potassium channels, AMP-activated protein kinase, activation of PKC (protein kinase C), and flux through the hexosamine pathway. Less well known is how cellularly heterogenous organs couple nutrient availability to prioritization of cell autonomous functions and appropriate growth...

... cell lines (J774.2 and RAW264.7 cells). In particular we find that glucose induces these effects by promoting an autocrine activation of Wnt signalling that is mediated by the hexosamine pathway and changes in N-linked glycosylation of proteins. These studies reveal that the Wnt/β-catenin system...

...Elodie MASSON; Nicolas WIERNSPERGER; Michel LAGARDE; Samer El BAWAB Alterations in proliferation and hypertrophy of renal mesangial cells are typical features of diabetic nephropathy. The HP (hexosamine pathway) has been proposed as a biochemical hypothesis to explain microvascular alterations due...
