283. Serum gonadotropin, prolactin, estrogen and progesterone levels throughout the menstrual cycle and pregnancy in the chimpanzeeFour luteolytic agents were administered to groups of pregnant rats to examine the quantitative relationship between serum progesterone levels and the maintenance of pregnancy....
Revisiting biochemistry basics, one recalls that cholesterol is the precursor molecule modified by the desmolase CYP11A into pregnenolone, then by a mitochondrial dehydrogenase into progesterone. This latter becomes testosterone (T) through CYP17 hydroxylase activity [3,7,[28], [29], [30], [31]...
They are responsible for correct development of genitals; they take part in the whole cycle of changes during pregnancy, as well as they play vital role in a various metabolic processes (fat metabolism, calcium metabolism, synthesis and assimilation of proteins and blood coagulability). The ...

Plasma progesterone levels and cocaine-seeking in freely cycling female rats across the estrous cycle. Drug Alcohol Depend 89: 183–189. Fuchs RA, Evans KA, Mehta RH, Case JM, See RE (2005). Influence of sex and estrous cyclicity on conditioned cue-induced reinstatement of cocaine-seeking ...
In a case report [25], two women diagnosed with LAM presented with abdominal lymphangioleiomyomas that exhibited growth patterns influenced by changes in estrogen levels during the menstrual cycle. As abnormal smooth muscle cells express both estrogen and progesterone receptors but are particularly respo...
Estrous cycle and sex differences in performance on anxiety tasks coincide with increases in hippocampal progesterone and 3a,5a-THP. Pharmacol Biochem Behav 67: 587–596. Frye CA, Walf AA (2002). Changes in progesterone metabolites in the hippocampus can modulate open field and forced swim test ...
An increase in estradiol, total luteinizing hormone activity (LH + CG) and progesterone levels was the first sign of pregnancy. High values were noted during 20 days following the mid-cycle LH peak (LH/CG values were about 0.2–0.5 µg/ml) while serum estrogen and progesterone levels ...
As mentioned in the section on Glu neurotransmission, there is elevated production of nitric oxide in the preoptic area on the afternoon of proestrus, when both estradiol and progesterone levels are high (d'Anglemont de Tassigny et al., 2007). Thus, via regulation of nNOS and soluble guanylyl...
In EEC pathogenesis, estrogen was found to inhibit PTEN expression through extensive experimental studies14,15,16. However, it is maintained a poorly understood mechanism, which the present study focused on. In recent years, pseudogene PTENP1, has been reported to regulate the levels of PTEN by ...
