Journal ArticleDOI
Biochemical measures in a population-based study: effect of fasting duration and time of day.
TL;DR: Even after fasting, biochemical measurements may still differ in relation to fasting duration and time of day, so it is important to standardize both the period of fasting and the time ofday as much as possible, and make adjustments where necessary.
Journal ArticleDOI
Metabolic Effects of Suppression of Nonesterified Fatty Acid Levels With Acipimox in Obese NIDDM Subjects
TL;DR: Longer overnight suppression of lipolysis and lipid oxidation in obese NIDDM lowers fasting blood glucose and HGO and increases peripheral and hepatic sensitivity to insulin in obeseNIDDM patients.
Journal ArticleDOI
Variation in the Calpain-10 Gene Affects Blood Glucose Levels in the British Population
Stephen Lynn,Julie Evans,Christopher J. White,Timothy M. Frayling,Andrew T. Hattersley,Douglass M. Turnbull,Yukio Horikawa,Nancy J. Cox,Graeme I. Bell,Mark Walker +9 more
TL;DR: It is concluded that genetic variation in the CAPN10 gene influences blood glucose levels in nondiabetic British subjects and that this is due, at least in part, to the effects of calpain-10 on the early insulin secretory response.
Journal ArticleDOI
Age-related decline in mitochondrial DNA copy number in isolated human pancreatic islets
Lynsey M. Cree,Sheila K Patel,Angela Pyle,Stephen Lynn,Douglass M. Turnbull,Patrick F. Chinnery,Mark Walker +6 more
TL;DR: The age-related decrease in mtDNA copy number that was observed in human pancreatic islet preparations may contribute to the age-dependent decline in pancreatic beta cell insulin secretory capacity.
Journal ArticleDOI
Precursor peptide-targeted mining of more than one hundred thousand genomes expands the lanthipeptide natural product family.
Mark Walker,Mark Walker,Sara M. Eslami,Kenton J. Hetrick,Sarah E. Ackenhusen,Douglas A. Mitchell,Wilfred A. van der Donk +6 more
TL;DR: Examination of the biosynthetic gene clusters revealed that enzymes installing secondary post-translational modifications are more widespread than initially thought and the precursor peptides encoded within these clusters are more diverse than previously appreciated, demonstrating that the lanthipeptide sequence-function space remains largely underexplored.
