progesterone

Progesterone (Pregn-4-ene-3,20-dione) is the major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production.

Ovalbumins is the main protein found in egg whites. Ovalbumins have various biological activities such as antibacterial, anticancer, antihypertensive, antioxidant and immunomodulatory activities. Ovalbumins are the most abundant proteins synthesized in estrogen- or progesterone- treated fallopian tubes. Ovalbumins are commonly used as markers to study hormone control of gene expression in fallopian tubes.
