Background: The decidua has been implicated in the "terminal pathway" of human term parturition, which is characterized by the activation of pro-inflammatory pathways in gestational tissues. However, the transcriptomic changes in the decidua leading to terminal pathway activation have not been systematically explored. This study aimed to compare the decidual expression of developmental signaling and inflammation-related genes before and after spontaneous term labor in order to reveal their involvement in this process...

Little information has so far been known on the effects of synthetic progestogen dydrogesterone (DDG) in organisms like fish. This study aimed to investigate the effects of DDG on the transcriptional and biochemical alterations in zebrafish eleuthero-embryos. Zebrafish eleuthero-embryos were analyzed for the transcriptional alterations by real-time quantitative PCR (RT-qPCR) and biochemical changes by attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FITR) after 144 h exposure to DDG...

Sharon J Parish, John A Gillespie
This review describes the evolving role of oral hormone therapy (HT) for treating menopausal symptoms and preventing osteoporosis, focusing on conjugated estrogens/bazedoxifene (CE/BZA). Estrogens alleviate hot flushes and prevent bone loss associated with menopause. In nonhysterectomized women, a progestin should be added to estrogens to reduce the risk of endometrial cancer. Use of HT declined since the Women's Health Initiative (WHI) studies showed that HT does not prevent coronary heart disease (CHD) and that conjugated estrogens/medroxyprogesterone acetate increased the risk of invasive breast cancer after nearly 5 years of use...

Progesterone Receptor Membrane Component 1 (PGRMC1) is located in many different subcellular locations with many different attested and probably location-specific functions. PGRMC1 was recently identified in the mitochondrial outer membrane where it interacts with ferrochelatase, the last enzyme in the heme synthetic pathway. It has been proposed that PGRMC1 may act as a chaperone to shuttle newly synthesized heme from the mitochondrion to cytochrome P450 (cyP450) enzymes. Here we consider potential roles that PGRMC1 may play in transferring heme, and other small hydrophobic ligands such as cholesterol and steroids, between the hydrophobic compartment of the membrane lipid bilayer interior to aqueous proteins, and perhaps to the membranes of other organelles...

In our previous study, we measured 0.23-13.67ng/L progestogens (progesterone, drospirenone, levonorgestrel) in natural waters in the catchment area of the largest shallow lake of Central Europe, Lake Balaton. Progestogen contaminations act as potent steroids with mixed progestagenic, androgenic and mild estrogenic effects that is why our aim was to investigate the morphological and molecular effects of mixture of progesterone, drospirenone, and levonorgestrel in environmentally relevant (10ng/L) and higher (50 and 500ng/L) exposure concentrations in common roach, Rutilus rutilus...

A biosensor detecting estrogens, progestogens and androgens in complex samples and in a single step is described. Three Arxula adeninivorans yeast strains were created, each strain producing a different recombinant human hormone receptor and a different fluorescent reporter protein. These strains were then mixed to create G1212/YRC102-hHR-fluo, the biological component of the biosensor. During incubation with G1212/YRC102-hHR-fluo, hormones present in a sample bind to their target receptor, which leads to the production of a specific fluorescent protein...

Over the past three decades, the prevalence of diabetes has increased four-fold. Coupled with the global obesity epidemic and aging of the world's population, a perfect metabolic storm is brewing. The influence of menopause and exogenous estrogen and progestogens must be included in this equation. In this review, criteria for diagnosing diabetes and recommendations for screening are described. The reported effects of menopause on diabetes risk in healthy women are reviewed as well as the relationship between established diabetes and the timing of menopause...

Menopausal symptoms include vasomotor symptoms (VMS), vulvar-vaginal atrophy, and loss of bone mass associated with an increased risk of fracture. Treatment of VMS consists of lifestyle changes, hormone treatment (estrogens with and without progestogens, tissue selective estrogens complex or conjugated estrogens and bazedoxifene [CE/BZA], progestogens, and tibolone), and nonhormonal treatments. Genitourinary symptoms due to vulvar-vaginal atrophy are treated with systemic and local hormones, moisturizer creams and gels, CE/BZA, and a selective estrogen receptor modulator (ospemifene)...

Tegillarca granosa Linnaeus, possesses various biological functions and has been used a Chinese traditional medicine more than one century, but there is no report about anti-hyperplasia of mammary gland (HMG) activity of drugs from T. granosa. In this study, we investigated the anti-HMG effect of protein extract named HSS from T. granosa. The HMG model of virgin female Sprague Dawley rats was prepared by injecting estrogen in the thigh muscle of the rats and progestogen consecutively. HMG rats were treated with either HSS or positive control drug by i...

The results of large clinical trials have led physicians and patients to question the safety of hormone therapy for menopause. In the past, physicians prescribed hormone therapy to improve overall health and prevent cardiac disease, as well as for symptoms of menopause. Combined estrogen/progestogen therapy, but not estrogen alone, increases the risk of breast cancer when used for more than three to five years. Therefore, in women with a uterus, it is recommended that physicians prescribe combination therapy only to treat menopausal symptoms such as vasomotor symptoms (hot flashes) and vaginal atrophy, using the smallest effective dosage for the shortest possible duration...

Synthetic progestins act as endocrine disrupters in fish but their risk to the environment is not sufficiently known. Here, we focused on an unexplored antiandrogenic progestin, chlormadinone acetate (CMA), and the antiandrogenic progestin cyproterone acetate (CPA). The aim was to evaluate whether their in vitro interaction with human and rainbowfish (Melanotaenia fluviatilis) sex hormone receptors is similar. Furthermore, we investigated their activity in zebrafish (Danio rerio) eleuthero-embryos. First, we studied agonistic and antagonistic activities of CMA, CPA, and 17α-ethinylestradiol (EE2), in recombinant yeast expressing either the human progesterone (PGR), androgen (AR), or estrogen receptor...
