Analysis of blood glucose in diabetic nude mice with transplanted cells showed that proinsulin production by these cells was strongly suppressed by GCV treatment in vivo as reflected by the reversal to hyperglycemia.
Apn has protective effects against hyperglycemia and can effectively enhance antioxidation, promote the secretion of insulin and reduce the accumulation of glycosylated products in T2DM mice; these effects were associated with inhibition of PKC and promotion of PKA signaling.
Hyperglycemia induced the expression of PKC-beta1 and PKC-beta2; however, only inhibition of PKC-beta1 but not PKC-beta2 led to a significant decrease of FGF-2 levels.
Taken together, our data suggest that hmunc13 serves as a diacylglycerol-activated, PKC-independent signaling pathway capable of inducing apoptosis and that this pathway may contribute to the renal cell complications of hyperglycemia.
At diagnosis of pediatric diabetes, absence of all islet autoantibodies and modest hyperglycemia (HbA<sub>1c</sub> <7.5% [58 mmol/mol]) should result in testing for GCK, HNF1A, and HNF4A MODY.

Glucagon explained up to 86% of the variance in glucagon-like peptide 1, whereas cortisol explained up to 89% of the variance in interleukin 6 in hyperglycemia after AP.
This report describes GCK-MODY in a Chinese family and stresses that in managing this condition it is important to avoid unnecessary drug treatment and excessive anxiety about mild hyperglycemia.
The SCI-hyperglycemia-curcumin group showed a statistically significant reduction in IL-6, IL-8, and TNF-α levels compared with the SCI-hyperglycemia group after SCI.
We assessed the contribution of hyperglycemia by comparing insulin sensitivity in control and GCK-MODY and the contribution of hyperinsulinemia by comparing GCK-MODY and type 1 diabetes.
Acute induction of insulin receptor knockout in adipocytes changed the substrate preference to fat before induction of a diabetic phenotype including hyperinsulinaemia and hyperglycaemia.
Hyperglycemia markedly upregulated the expression of glycolytic enzymes (glucokinase and 6-phosphofructo-1-kinase, PFK1) 5 h following glucose administration, while at 24 h posttreatment, it increased isocitrate dehydrogenase (IDH) activity, a key enzyme of the tricarboxylic acid cycle, and the expression of lipogenic factors (PGC1β, Lpin1, and SREBP1).
This case raises the question as to whether hyperglycaemia in GCK-MODY may increase the risk of fetal caudal regression syndrome as reported in women with pre-existing diabetes mellitus.
In conclusion, this novel GCK mutant rabbit generated with the CRISPR/Cas9 system mimics most, if not all, histopathological and functional defects seen in MODY-2 patients such as hyperglycemia and will be a valuable rabbit model for preclinical studies and drug screening for diabetes as well as for studying the pathophysiological role of glucokinase.
