Gestodene
Based on 1 Customer Validation
Gestodene (SHB 331; WL 70) is an orally active synthetic progestogen compound of the 19-nortestosterone class. Gestodene binds with high affinity to the progesterone receptor, inhibits 5α-reductase, binds to androgen and aldosterone receptors, and inactivates CYP3A. Gestodene acts as a positive allosteric modulator of PAR1, enhances PAR1-mediated signaling pathways, and is capable of increasing the activation potency of PAR1-AP toward PAR1, thereby promoting ERK1/2 phosphorylation, receptor internalization, cell morphological changes, and human platelet aggregation. Gestodene and its A-ring reduced metabolites promote the proliferation, differentiation, and mineralization of neonatal rat osteoblasts. Gestodene itself has no binding capacity for estrogen receptors, and this osteogenic activity depends on intracellular metabolism to generate A-ring reduced products with estrogen-like agonistic activity. Gestodene is useful for research on diseases related to progesterone secretion and diseases related to thrombosis.

In Vitro
Gestodene exhibits a high relative binding affinity for the progesterone receptor, shows low to moderate binding affinity for the androgen receptor, and has weak binding capacity for the estrogen receptor[1].
Gestodene inhibits the hydroxylation of ethinyl estradiol in a concentration-dependent manner in human liver microsomes and also inhibits the oxidative metabolism of Cyclosporine and Diazepam[1].
Gestodene (GDN) (1-500 nM; 1-25 days) stimulates the proliferation of neonatal rat calvarial osteoblasts, increases alkaline phosphatase activity in neonatal rat calvarial osteoblasts, and increases cell-associated osteocalcin content in neonatal rat calvarial osteoblasts; the 5α-reductase inhibitor Finasteride (HY-13635) and the aldosterone ketosteroid dehydrogenase inhibitor Flufenamic acid (HY-B1221) inhibit the Gestodene-induced increase in alkaline phosphatase activity[2].
Gestodene (50-500 nM; 25 days) increases cell-associated calcium content in neonatal rat calvarial osteoblasts[2].
Gestodene (1-250 nM; 18 h) shows no binding affinity for estrogen receptors in the cytosolic fraction of neonatal rat calvarial osteoblasts[2].
Gestodene is extensively metabolized to A-ring reduced derivatives (5α gestodene, 3α,5α gestodene, and 3β,5α gestodene) in rat anterior pituitary, hypothalamus, and ventral prostate homogenates[3].
Gestodene (3 μM; 3 days; 4-16 h; 30 min) enhances PAR1-AP-induced proliferation, migration, and ERK1/2 phosphorylation in A2058 cells, HaCaT cells, and HDF cells in a PAR1-dependent manner; this enhancing effect is blocked by Vorapaxar (HY-10119)[4].
Gestodene acts as a positive allosteric modulator of PAR1 in HT29 cells, enhancing PAR1-AP- and thrombin-induced intracellular calcium levels with EC50 values of 8.15 μM and 4.54 μM, respectively, without affecting PAR2 or PAR4 activity[5].
Gestodene (10 μM) enhances PAR1-AP-induced intracellular calcium levels in MEG-01 cells, reducing the EC50 of PAR1-AP from 6.58 μM to 3.41 μM[5].
Gestodene (10 μM; 10 min) enhances PAR1-AP-induced ERK1/2 phosphorylation in MEG-01 cells through a PAR1-dependent mechanism[5].
Gestodene (10 μM) enhances PAR1-AP-induced PAR1 internalization in HT29 cells, and this effect is blocked by Vorapaxar[5].
Gestodene (10 μM; 30 min) enhances PAR1-AP-induced morphological changes (decreased circularity) in MEG-01 cells, and this effect is blocked by Vorapaxar[5].
Gestodene (GDN) (10-100 nM; 6 h) significantly increases insulin 2 and glucokinase gene expression in isolated rat pancreatic islets[8].
Gestodene (100 nM; 6 h) significantly enhances glucose-stimulated insulin secretion in isolated rat pancreatic islets cultured in 11 mM D-glucose; moreover, in the presence of steroid-metabolizing enzyme inhibitors, the Gestodene-induced increase in insulin 2 and glucokinase gene expression in rat pancreatic islets is suppressed, indicating that the stimulatory effect of Gestodene is exerted through enzyme-generated tetrahydro-reduced metabolites[8].
Gestodene (10 min) acts as a selective positive allosteric modulator of PAR1 in HT29 cells, with no effect on PAR2 or PAR4; it enhances PAR1-AP-induced calcium signaling in A2058 cells in a PAR1-dependent manner and shifts the dose-response curve to the left (EC50 decreases from 3.1 to 0.8 μM)[4].
Gestodene (3 μM; 24 h) enhances PAR1-AP-induced expression of MMP-1, MMP-2, MMP-3, MMP-10, and fibronectin in HaCaT cells as well as COL1A1 expression in NIH-3T3 cells through a PAR1-dependent signaling pathway[4].
Gestodene (GES) (10-10-10-6 M; 7 days) stimulates the growth of T47D-A breast tumor subclone cells but does not stimulate the growth of T47D-S breast tumor subclone cells[7].
Gestodene (10-10-10-6 M; 7 days) abolishes the estradiol-induced cell proliferation effect in T47D-S human breast tumor subclone cells; the proliferation effect induced in T47D-A cells is partially inhibited by antiestrogens (4-Hydroxytamoxifen, ICI 164384) and is not antagonized by antiprogestins (RU 38486 (HY-13683), Org 31710)[7].

Kinase activity and phosphorylation assays
Kinase activity assays measure the ability of kinases to transfer phosphate groups from ATP to specific substrates, while phosphorylation assays detect the presence and levels of phosphorylated proteins. Common methods include radiolabeled ATP incorporation (e. g. ,), ADP release detection via bioluminescence (e. g. ,[3]), enzyme-linked immunosorbent assays (ELISA) for phospho-specific epitopes (e. g. ,[6]), and microtiter-based formats for high-throughput screening (e. g. ,[8]). The ADP-Glo assay quantifies kinase activity by measuring ADP produced during phosphorylation using a luciferase-based system. Radiometric assays involve autoradiography or scintillation counting after incorporation of 32P-labeled ATP into substrate proteins. ELISA-based approaches rely on phospho-specific antibodies to detect activated kinases in cell lysates or purified samples.
-
Western Blot
Western blotting (WB) is a commonly used experimental method in molecular biology, biochemistry, and immunogenetics for identifying and quantifying target proteins. It combines gel electrophoresis with immunoassay, enabling researchers to analyze protein expression, post-translational modifications, and molecular weight.
-
Mesenchymal stromal/stem cell osteogenic differentiation
Mesenchymal stromal/stem cells can be induced toward an osteoblast-like lineage in vitro by culture in osteogenic medium containing dexamethasone, ascorbic acid or ascorbate-2-phosphate, and β-glycerophosphate; the differentiation process is commonly evaluated by alkaline phosphatase activity, osteogenic marker expression, collagenous matrix formation, and calcium-rich matrix mineralization. The main readouts are alkaline phosphatase activity as an early osteogenic marker and Alizarin Red S staining as a calcium-deposit readout for mineralized extracellular matrix; Alizarin Red S can be inspected microscopically or extracted and measured colorimetrically at 405 nm.

Research Protocol for Endocrine Diseases
Endocrine diseases often arise from disrupted hormone production, hormone signaling, or target-tissue responsiveness; for diabetes-focused endocrine disease models, insulin signaling regulates glucose uptake, hepatic glucose output, lipid metabolism, and β-cell compensation. Type 2 diabetes develops through interacting defects in insulin resistance, β-cell dysfunction, adipose inflammation, hepatic glucose overproduction, altered incretin signaling, and ectopic lipid metabolism. A major unresolved question is whether endocrine dysfunction is driven primarily by target-tissue insulin resistance, intrinsic β-cell failure, immune/inflammatory stress, or combined multi-organ failure that differs by disease stage.
-
Protocol for Kinase activity and phosphorylation assays
Kinase activity assays measure transfer of phosphate from ATP to a protein or peptide substrate, generating phosphorylated substrate, ADP, or incorporated radiolabeled phosphate as the readout; phosphorylation assays measure site-specific phosphorylation in cells or tissues as a proxy for kinase-pathway activation, inhibition, or substrate regulation. Phosphorylation can be detected by phospho-specific Western blot, immunoprecipitation kinase assay, phospho-immunofluorescence, phospho-flow cytometry, luminescent ADP detection, radiolabeled ATP incorporation, or reporter-based pathway assays, and these readouts can be applied to cancer cells, primary neurons, mouse tumors, organoids, inflammatory macrophages, ferroptosis studies, and mitophagy studies when the kinase target is biologically relevant.
-
Cell Viability Determination by MTT Colorimetric Assay
The following protocol uses the MTT colorimetric assay as a classic literature-established method for assessing cell viability/metabolic activity in cultured mammalian cells. MTT[3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] is reduced by metabolically active cells to a colored formazan product; the amount of formazan is quantified spectrophotometrically and provides an indirect measure of metabolically active viable cells. Importantly, MTT reduction reflects cellular oxidoreductase/metabolic activity rather than an absolute direct count of living cells, so changes in cellular metabolism can alter the signal independently of cell number.
