Define regulation of L-PK enzymes by starvation & refeeding?
L-PK catalyzes the conversion of phosphoenolpyruvate to pyruvate and plays an important role in directing pyruvate toward glucose synthesis in starved animals or towards oxidation of and incorporation into long-chain fatty acids in fed animals. The level of L-PK decreases greatly in starved rats and is increased when starved rats are refed, particularly if the diet contains a high level of carbohydrate. In diabetic animals, L-PK concentration is very low; treatment with insulin restores normal levels. Feeding a diet high with insulin restores normal levels. Feeding a diet high in fructose, but not glucose, partly restores the normal level of L-PK in a diabetic rat. These changes in concentration of L-PK are due to changes in the synthesis rate of the protein. Thyroid hormone also stimulates accumulation of L-PK protein in thyroidectomized rats.
The level of L-PK and WA is increased in rats treated with insulin and decreased in diabetic animals or animals treated with glucagon s or cyclic adenosine monophosphate (CAMP). Fructose and certain other simple sugars cause an increased accumulation of L-PK and its mRNA, even in diabetic animals. Regulation of rate of synthesis of L-PK mRNA is not exclusively transcriptional, and different hormones may regulate expression of this gene by regulating different reactions in the gene expression pathway.
The intermediates in the cycle give precursors for various biosynthetic pathways. An instance is as given below: - From citrate synthesis of fatty acids; - Amino acid synth
