Improvement of glucose tolerance in type 2 diabetic patients: traditional vs. modern insulin regimens (results from the Austrian Biaspart Study).

Objective: Major advantages of modern insulin regimens containing premixed insulin analogues in comparison to traditional insulin regimens have not been evaluated yet. The aim of the present study was to investigate whether meal-related (breakfast, lunch, dinner) application of biphasic insulin aspart 30 (BIAsp 30) provides better glycaemic control than administration of biphasic human insulin 30 (BHI 30) twice per day.

Research Design And Methods: In a multi-centre, randomized, open-label parallel trial, a total of 177 patients with type 2 diabetes mellitus were exposed to the two different insulin regimens described above over a study period of 24 weeks.

GAC1 may encode a regulatory subunit for protein phosphatase type 1 in Saccharomyces cerevisiae.

Elevated dosage of the GAC1 gene from the yeast Saccharomyces cerevisiae causes hyperaccumulation of glycogen whereas a gene disruption of GAC1 results in reduced glycogen levels. Glycogen synthase is almost entirely in the active, glucose 6-phosphate-independent, form in cells with increased gene dosage of GAC1 whereas the enzyme is mostly in the inactive form in strains lacking GAC1. GAC1 encodes an 88 kDa protein that is similar to the regulatory subunit (RG1) of phosphoprotein phosphatase type 1 (PP-1) from skeletal muscle that targets PP-1 to glycogen particles.
