kynurenine and Menopause

kynurenine has been researched along with Menopause in 8 studies

Kynurenine: A metabolite of the essential amino acid tryptophan metabolized via the tryptophan-kynurenine pathway.
kynurenine : A ketone that is alanine in which one of the methyl hydrogens is substituted by a 2-aminobenzoyl group.

Menopause: The last menstrual period. Permanent cessation of menses (MENSTRUATION) is usually defined after 6 to 12 months of AMENORRHEA in a woman over 45 years of age. In the United States, menopause generally occurs in women between 48 and 55 years of age.

"Women with early breast cancer were given a loading dose of L-tryptophan after mastectomy and a comparison made between their excretion of metabolites of the kynurenine pathway and the rate of recurrence of the disease."7.65Tryptophan metabolism and recurrence rates of patients with breast cancer after mastectomy. ( Bell, ED; Bulbrook, RD; Hayward, JL; Tong, D, 1975)

( Bell, ED; Bulbrook, RD; Hayward, JL; Tong, D, 1975)
"The kynurenine load test was introduced to distinguish, in vivo, between abnormal tryptophan metabolism caused by induction of tryptophan oxygenase or by impaired kynureninase function."1.26The kynurenine load test, an adjunct to the tryptophan load test. ( Arend, RA; Brown, RR; Wolf, H, 1980)
