Distribution of the multiple molecular forms of glucose-6-phosphate dehydrogenase in different physiological states. 1979

H L Chang, and D Holten, and R Karin

The distribution of the multiple molecular forms of rat liver and mammary gland glucose-6-phosphate dehydrogenase was determined by electrophoresis on 5% polyacrylamide gels. In both of these organs, changes in the distribution of enzyme activity among the several forms was slight even when approximately 20- to 40-fold changes in enzyme specific activity were achieved by fasting-refeeding experiments (for liver) or during pregnancy and lactation (for mammary gland). It was concluded that the induction of glucose-6-phosphate dehydrogenase in these two organs occurs without any major redistribution among the multiple molecular forms of this enzyme.

UI	MeSH Term	Description	Entries
D007527	Isoenzymes	Structurally related forms of an enzyme. Each isoenzyme has the same mechanism and classification, but differs in its chemical, physical, or immunological characteristics.	Alloenzyme,Allozyme,Isoenzyme,Isozyme,Isozymes,Alloenzymes,Allozymes
D007774	Lactation	The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.
