Exempel på progesterone

• These mechanical signals can be blocked by progesterone either by a direct action of this hormone or possibly through the support of stretch-induced uterine hypertrophy.

• We also verified that in our experimental conditions the three drugs inhibited progesterone-induced oocyte maturation.

• In the latter, maturation was induced by progesterone (1 mg/ml).

• The role of calcium in progesterone-induced meiotic maturation in amphibian oocytes remains unclear.

• In amphibians, oocyte maturation is induced by progesterone produced by the follicular cells.

• Neither the receptor for progesterone nor the subsequent events that lead to maturation are understood.

• This finding suggests that the participation of membrane phospholipids could be the same in progesterone-induced and muscimolinduced maturation.

• Not mutually exclusive is the possibility that metabolism of progesterone is enhanced, particularly by conversion of progesterone to its primary metabolite 20a-hydroxyprogesterone.

• Denuded oocytes were matured in vitro, spontaneously or by progesterone treatment (1 ug/ml), and inseminated with homologous spermatozoa.

• Incompetent oocytes were denuded and preincubated in the presence of the blockers for 30 min and maturation was then induced by progesterone (1 g/ml).

• Adjuvant therapy for postmenopausal patients with operable breast cancer who have estrogen-receptor or progesterone-receptor-positive tumors.

• However, progesterone may also act through a non-genomic mechanism to inhibit contractility.

• Evidence that nitric oxide synthase is involved in progesterone-induced acrosome exocytosis in mouse spermatozoa.

• Progesterone represses interleukin-8 and cyclo-oxygenase-2 in human lower segment fibroblast cells and amnion epithelial cells.

• That is, oocytes co-treated with progesterone and demecolcine elicited the normal membrane depolarisation observed with progesterone alone.
