Creatine transporters: A reappraisal
Molecular and Cellular Biochemistry, 2004Creatine (Cr) plays a key role in cellular energy metabolism and is found at high concentrations in metabolically active cells such as skeletal muscle and neurons. These, and a variety of other cells, take up Cr from the extra cellular fluid by a high affinity Na(+)/Cl(-)-dependent creatine transporter (CrT). Mutations in the crt gene, found in several

Brain Creatine Kinase and Creatine Transporter Proteins in Normal and Creatine-Treated Rabbit Pups
Developmental Neuroscience, 2000Systemic creatine (Cr) supplementation increases brain phosphocreatine (PCr) and prevents hypoxic seizures in 15-day-old rabbits . Between 5 and 30 days of age during normal development, rabbit gray matter mitochondrial creatine kinase (Mi-CK) increases 400% while cytosolic CK (BB-CK) increases 60%.

Effects of Creatine Supplementation on Renal Function: A Systematic Review and Meta-Analysis.
Journal of renal nutrition, 2019Creatine supplements are intended to improve performance, but there are indications that it can overwhelm liver and kidney functions, reduce the quality of life, and increase mortality.

Creatine and Creatine Deficiency Syndromes: Biochemical and Clinical Aspects
Pediatric Neurology, 2010Creatine deficiency syndromes, which have only recently been described, represent a group of inborn errors of creatine synthesis (L-arginine-glycine amidinotransferase deficiency and guanidinoacetate methyltransferase deficiency) and transport (creatine transporter deficiency). Patients with creatine deficiency syndromes present with mental retardation

A method for the determination of creatine in blood serum with creatine phosphokinase
Clinica Chimica Acta, 1966Abstract A method is described for the determination of creatine in blood serum with creatine phosphokinase on the principles of that of Tanzer and Gilvarg 1 . Serum is treated with a solution of iodine and then protein is removed with barium hydroxide and zinc sulfate.

Since the first description of a creatine deficiency syndrome, the guanidinoacetate methyltransferase (GAMT) deficiency, in 1994, the two further suspected creatine deficiency syndromes--the creatine transporter (CrT1) defect and the arginine:glycine amidinotransferase (AGAT) deficiency were disclosed.

AbstractRecent reports highlight the utility of in vivo magnetic resonance spectroscopy (MRS) techniques to recognize creatine deficiency syndromes affecting the central nervous system (CNS). Reported cases demonstrate partial reversibility of neurologic symptoms upon restoration of CNS creatine levels with the administration of oral creatine.
