Department of Clinical Pathology, St George's Hospital Medical School, London, UK.

1. Alkaline phosphatase activity in NMU-induced rat mammary tumours was compared with activity in normal and lactating mammary gland. 2. Both tumour and normal mammary alkaline phosphatase were sensitive to heat inactivation and inhibition by phenylalanine. 3. Specific activity of enzyme in tumours was comparable to normal mammary tissue. 4. Mammary gland alkaline phosphatase increased markedly in late pregnancy and early lactation. 5. Bromocryptine treatment had no effect on enzyme activity in lactating mammary gland.

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.
