Genistein inhibits human papillary thyroid cancer cell detachment, invasion and metastasis
In conclusion, for the first time, our study suggested that genistein has anticarcinoma effect for PTC patients in the range of 2.5 and 80 μg/ml in thyroid carcinoma cells, which was probably through cytoplasmic translocation of β-catenin. Further study will be needed to determine whether genistein could be used in clinical trial of high-risk PTC.

Genistein suppresses psoriasis-related inflammation through a STAT3-NF- κB-dependent mechanism in keratinocytes.
In this study, we investigated the effects of genistein on imiquimod (IMQ)-induced psoriasis-like skin lesions in vivo and explored the mechanisms underlying those effects in vitro. It was found that genistein can significantly improve IMQ-induced pathological scores of cutaneous skin lesions in mice, reduce epidermal thickness, and inhibit the expression of inflammatory factors，including interleukin (IL)-1β, IL-6, tumour necrosis factor-alpha (TNF-α), chemokine ligand 2 (CCL2), IL-17 and IL-23. In vitro studies, genistein inhibited the proliferation of human keratinocyte HaCaT cells and inhibited the expression of inf...

MiR-34a/sirtuin-1/foxo3a is involved in genistein protecting against ox-LDL-induced oxidative damage in HUVECs.
In this study, human umbilical vein endothelial cells (HUVECs) were pretreated with genistein at different concentrations (10nM, 100nM and 1000nM) for 6h and then exposed to ox-LDL (50mg/L) for another 24h. Results showed that genistein restrained reactive oxygen species (ROS) and malondialdehyde (MDA) production, and ameliorated the inhibitory effect on superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and glutathione peroxidase (GPx) activity elicited by ox-LDL stimulation. The effects of genistein were correlated with the upregulation of sirtuin-1 via inhibiting miR-34a, and were abolished by sirtuin-1 siRNA...

Protective effects of marein on high glucose-induced glucose metabolic disorder in HepG2 cells
Conclusions Consequently, marein improved insulin resistance induced by high glucose in HepG2 cells through CaMKK/AMPK/GLUT1 to promote glucose uptake, through IRS/Akt/GSK-3β to increase glycogen synthesis, and through Akt/FoxO1 to decrease gluconeogenesis. Marein could be a promising leading compound for the development of hypoglycemic agent or developed as an adjuvant drug for diabetes mellitus. Graphical abstract
