BACKGROUND Previously, we found that genistein at low concentrations stimulates the growth of human uterine leiomyoma (LM) cells, but not uterine smooth muscle (myometrial) cells (SMC). The aim of this study was to understand the molecular mechanism whereby genistein causes hyperproliferation of LM cells. METHODS The effects of genistein at 1 microg/ml on LM cells and SMC were evaluated using...

Microglia is one of the first innate immune components. These cells account about 5 to 10% of the entire adult brain cells and are activated by trauma. Complex-mediated inflammatory responses occur through cellular and molecular events during and after the traumatic brain injury (TBI). In-lesion area astrocytes, microglia, and damaged neurons begin to secrete cytokines and chemokines. Microglia...

Hypoxia-inducible factor 1 alpha (HIF-1 alpha) and the intracellular dioxin receptor mediate hypoxia and dioxin signalling, respectively. Both proteins are conditionally regulated basic helix-loop-helix (bHLH) transcription factors that, in addition to the bHLH motif, share a Per-Arnt-Sim (PAS) region of homology and form heterodimeric complexes with the common bHLH/PAS partner factor Arnt. Her...

At present, a constant progress in pathophysiology understanding and treatment of the chronic heart failure (CHF) is arising. The current CHF pharmacotherapy is complex, involving factors affecting the renin-angiotensin-aldosterone system (RAAS), beta-blockers, diuretics and vasodilatators. There are also significant efforts to introduce in CHF pharmacology novel therapeutic strategies, based o...

Purpose of this study was to screen the active compounds Zhenwu decoction and their gene targets in treatment non-alcoholic fatty liver disease by network pharmacology cytological validation test. The candidate related were obtained from traditional Chinese medicine system database PharmMapper. disease-related genes online Mendelian inheritance man, GeneCards DisGeNET databases. Molecular docki...

PURPOSE To characterize the constitutively activated epidermal growth factor receptor in a lens epithelial cell population experiencing initial stages of lens fiber formation, the chick lens annular pad. METHODS Phosphotyrosine levels of the receptor were examined with western blot analysis and immunoprecipitation after ligand stimulation. Endogenous receptor ligands were immunologically iden...

Gene expression data obtained in mouse heart indicate that increased expression for the nuclear receptor, peroxisomal proliferator activated receptor alpha (PPARalpha), prompts the postnatal transition from predominantly carbohydrate to fatty acid oxidation preference. However, no phenotypic or proteomic data are available to confirm downstream signaling and metabolic transition in mice. We stu...

Recently, it has been demonstrated that TNF-alpha and LPS induce the expression of suppressor of cytokine signaling 3 (SOCS3) and inhibit IL-6-induced STAT3 activation in macrophages. Inhibitor studies suggested that both induction of SOCS3 and inhibition of IL-6-induced STAT3 activation depend on the activation of p38 mitogen-activated protein kinase. Since recruitment of the tyrosine phosphat...

Hepatotropism is a prominent feature of hepatitis B virus (HBV) infection. Cell lines of nonhepatic origin do not independently support HBV replication. Here, we show that the nuclear hormone receptors, hepatocyte nuclear factor 4 and retinoid X receptor alpha plus peroxisome proliferator-activated receptor alpha, support HBV replication in nonhepatic cells by controlling pregenomic RNA synthes...

Human Valpha24NKT cells are activated by alpha-galactosylceramide (alpha-GalCer)-pulsed dendritic cells in a CD1d-dependent and a T-cell receptor-mediated manner. Here, we demonstrate that CD4(+)V alpha 24NKT cells derived from a patient with acute myeloid leukemia (AML) M4 are phenotypically similar to those of healthy donors and, in common with those derived from healthy donors, express tumor...
