Stress-related symptoms are a global concern, impacting millions of individuals, yet effective and safe treatments remain scarce. Although multiple studies have highlighted the stress- alleviating properties of saffron extract, the underlying mechanisms remain unclear. This study employs the unpredictable chronic mild stress (CMS) animal model to investigate the impact of a standardized saffron extract, Affron (AFN), on hypothalamic-pituitary-adrenal (HPA) axis regulation and neuroplasticity in Wistar rats following repeated oral administration.

In the regulation of inflammatory responses and skin homeostasis, the skin and its microbiota are closely related. Studies have reported that lactic acid bacteria extracts can improve the skin condition and microbiota. In our previous study, we developed probiotic lysates, which are efficacious in improvement of human skin cells and the skin barrier.

HDB1258 was cultured in the lava seawater (LS) to improve its probiotic properties. It increased adhesive ability to mucin with mRNA expression levels of chaperone proteins (such as GroEL/ES, DnaKJ, and HtrA).

The mineralization, anabolic and catabolic factors, and the amount of cytokines within the articular cartilage of rats were measured after administration of MIA. We found that dietary supplementation with methylsulfonylmethane (positive control) and FS (FS 100 mg/kg body weight [b.

In the FCCE intake groups, body weight gain and adipocyte area were significantly reduced, especially body weight gain in the 250 mg/kg FCCE group (G4) decreased by 37%, respectively, compared with negative control group (G2, HFD group). After oral administration of the FCCE, the increase of serum low-density lipoprotein (LDL)-cholesterol induced by HFD was suppressed significantly, as well as the level of aspartate aminotransferase, and alanine aminotransferase, which are markers of hepatitis induced by obesity.

Soybeans are major natural sources of isoflavones, with high estrogen receptor (ER)-β selectivity. The objective of this study therefore was to develop a solvent-mediated extraction method for soybean germinated embryos (SGEs) and to investigate the biological activities of the extract.

This study investigated the effect of tartary buckwheat extracts (TBEs) on adipogenesis and inflammatory response in 3T3-L1 cells. TBEs inhibited lipid accumulation, triglyceride content, and glycerol-3-phosphate dehydrogenase (GPDH) activity during adipocyte differentiation of 3T3 L1 cells.

Wrinkles were induced by exposing the skin of hairless mice to ultraviolet B (UVB) irradiation for 14 weeks. Hyaluronic acid was administered to the mice for 14 weeks including 4 weeks before experiments.

This study was aimed at elucidating the molecular mechanisms underlying the SERM properties of the extract of Korean-grown Opuntia ficus-indica (KOFI). The KOFI extract induced estrogen response element (ERE)-driven transcription in breast and endometrial cancer cell lines and the expression of endogenous estrogen-responsive genes in breast cancer cells.

A high-throughput LC/MS-ELSD based library approach of the extract in combination with the NF-κB and MTT assays revealed the styryl lactone (+)-altholactone (2) was responsible for the activity.

A unique element of this study was that the bengamide analogs were isolated from two disparate sources, Myxococcus virescens (bacterium) and Jaspis coriacea (sponge). Comparative LC-MS/ELSD and NMR analysis facilitated the isolation of M.

LY2066948, a novel SERM in development by Eli Lilly for the treatment of uterine fibroids and myomas, has structural similarity to the equine estrogen equilenin present in hormone replacement formulations; both contain a naphthol group susceptible to oxidative metabolism to o-quinones. LY2066948 was synthesized and assayed for antiestrogenic activity, and in cell culture was confirmed to be a more potent antiestrogen than the prototypical SERM, 4-hydroxytamoxifen.

Its absolute configuration, 2R,10R,11S,19R, was established using NMR, HRESIMS, and CD data plus insights derived from molecular models. A possible route for its biogenesis is proposed, and biological properties were explored against cancer cell lines and in an NFκB inhibition assay.

CDs themselves are anticipated to have low membrane permeability because of relatively high hydrophilicity and molecular weight. CD derivatization with 17-beta estradiol (E(2)) was explored extensively using a number of different click chemistries and the cell membrane permeability of synthetic CD-E(2) conjugate was explored by cell reporter assays and confocal fluorescence microscopy.

The formation of stable stereoisomeric cyclic 4-OHEN-DNA adducts has been reported in vitro and in vivo, but their removal by DNA repair processes in cells has not been determined.

View Article and Find Full Text PDFFollicle-stimulating hormone (FSH) comprises an alpha subunit and a beta subunit, whereas the FSH receptor consists of two halves with distinct functions: the N-terminal extracellular exodomain and C-terminal membrane-associated endodomain. FSH initially binds to exodomain, and the resulting FSH/exodomain complex modulates the endodomain and generates signal. However, it has been difficult to determine which subunit of FSH contacts the exodomain or endodomain and in what orientation FSH interacts with them.
View Article and Find Full Text PDFThe human follicle-stimulating hormone (FSH) receptor consists of two distinct domains of approximately 330 amino acids, the N-terminal extracellular exodomain and membrane-associated endodomain including three exoloops and seven transmembrane helices. The exodomain binds the hormone with high affinity, and the resulting hormone/exodomain complex modulates the endodomain where receptor activation occurs. It has been an enigma whether the hormone interacts with the endodomain.
