Applications of multi-nuclear magnetic resonance spectroscopy at 7T.

World journal of radiology

Stephenson MC, Gunner F, Napolitano A, Greenhaff PL, Macdonald IA, Saeed N, Vennart W, Francis ST, Morris PG.
PMID: 21532871
World J Radiol. 2011 Apr 28;3(4):105-13. doi: 10.4329/wjr.v3.i4.105.

AIM: To discuss the advantages of ultra-high field (7T) for (1)H and (13)C magnetic resonance spectroscopy (MRS) studies of metabolism.METHODS: Measurements of brain metabolites were made at both 3 and 7T using (1)H MRS. Measurements of glycogen and lipids...

Potential role for pyruvate kinase M2 in the regulation of murine cardiac glycolytic flux during in vivo chronic hypoxia.

Bioscience reports

Handzlik MK, Tooth DJ, Constantin-Teodosiu D, Greenhaff PL, Cole MA.
PMID: 33973628
Biosci Rep. 2021 Jun 25;41(6). doi: 10.1042/BSR20203170.

Carbohydrate metabolism in heart failure shares similarities to that following hypoxic exposure, and is thought to maintain energy homoeostasis in the face of reduced O2 availability. As part of these in vivo adaptations during sustained hypoxia, the heart up-regulates...

PPARα, δ and FOXO1 Gene Silencing Overturns Palmitate-Induced Inhibition of Pyruvate Oxidation Differentially in C2C12 Myotubes.

Biology

Chien HC, Constantin D, Greenhaff PL, Constantin-Teodosiu D.
PMID: 34827089
Biology (Basel). 2021 Oct 25;10(11). doi: 10.3390/biology10111098.

The molecular mechanisms by which free fatty acids (FFA) inhibit muscle glucose oxidation is still elusive. We recently showed that C2C12 myotubes treated with palmitate (PAL) presented with greater protein expression levels of PDK4 and transcription factors

Antecubital Vein Cannula Position Impacts Assessment of Forearm Glucose Uptake During an Oral Glucose Challenge in Healthy Volunteers.

Experimental and clinical endocrinology & diabetes : official journal, German Society of Endocrinology [and] German Diabetes Association

Bétry C, Nixon AV, Greenhaff PL, Simpson EJ.
PMID: 33096578
Exp Clin Endocrinol Diabetes. 2020 Oct 23; doi: 10.1055/a-1275-4038. Epub 2020 Oct 23.

INTRODUCTION: Skeletal muscle is a major site for whole-body glucose disposal, and determination of skeletal muscle glucose uptake is an important metabolic measurement, particularly in research focussed on interventions that impact muscle insulin sensitivity. Calculating arterial-venous difference in blood...

Degenerin channel activation causes caspase-mediated protein degradation and mitochondrial dysfunction in adult C. elegans muscle.

Journal of cachexia, sarcopenia and muscle

BACKGROUND: Declines in skeletal muscle structure and function are found in various clinical populations, but the intramuscular proteolytic pathways that govern declines in these individuals remain relatively poorly understood. The nematode Caenorhabditis elegans has been developed into a model...

Metabolomics as an Important Tool for Determining the Mechanisms of Human Skeletal Muscle Deconditioning.

International journal of molecular sciences

Alldritt I, Greenhaff PL, Wilkinson DJ.
PMID: 34948370
Int J Mol Sci. 2021 Dec 17;22(24). doi: 10.3390/ijms222413575.

Muscle deconditioning impairs both locomotor function and metabolic health, and is associated with reduced quality life and increased mortality rates. Despite an appreciation of the existence of phenomena such as muscle anabolic resistance, mitophagy, and insulin resistance with age...
