Objective(s): Genistein, as a phytoestrogen found in legumes, has several biological activities in general and anti-diabetic activity particularly. In this study, we investigated the effect of genistein on proteins involved in β-cell proliferation, survival and apoptosis to further reveal its anti-diabetic potential in the ovariectomized diabetic rat. Materials and Methods: We used three-month-...

Objective(s): In previous studies, researchers observed that doxepin could improve cognitive processes and has protective effectson the central nervous system. Thus, this study was designed to analyze the effects of doxepin on β-amyloid (Aβ)-induced memory impairment and neuronal toxicity in ratand to explore the underlying mechanism. Materials and Methods: Rats were treated with Aβ1-42 and dox...

Objective(s): Present study investigated the neuroprotective effects of selegiline and the molecular mechanisms involved in methamphetamine-induced neurotoxicity.Materials and Methods: Male wistar rats were randomly divided into six groups (10 rats in each group). Group 1 and group 2 received normal saline and methamphetamine (10 mg/kg),...

background: the conventional chemotherapeutic regimens which applied for treatment of acute myeloid leukemia (aml) mostly target tumor bulk but not leukemic stem cells (lscs). aberrant expression or activation of mediators such as osteopontin (opn) or pi3k/pten/akt/mtor pathway plays a key role in making prone to develop leukemia. preventing or treating cancer by curcumin (cur) has been suggest...

Obesity and exercise lead to structural changes in heart such as cardiac hypertrophy. The underlying signaling pathways vary according the source of overload, be it physiological (exercise) or pathologic (obesity). pathway relies more on PI3K-Akt while involves calcineurin-Nuclear factor activated T-cells activation fibrosis accumulation. Independently, polyphenols have demonstrated prevent The...

background: it has been reported that secreted frizzled-related protein-4 known as an antagonist of wnt signaling pathway plays a role in luteinization process of rodent granulosa cells. the purpose of this study was twofold: 1) to determine whether recombinant human secreted frizzled-related protein-4 (rhsfrp-4) could directly induce terminal differentiation of rat granulosa cells (gcs) and 2)...

Background: NUAK1 is a serine/threonine kinase member of the AMPKα-family, whose high expression associated with poor prognosis. However, regulation and functions in cancer remain poorly characterized. Here, we investigated NUAK1’s role signaling. Materials Methods: We performed bioinformatic analysis TCGA to study correlation between EGFR Akt phosphorylation several cancers. mainly studies on ...

background tuberculosis (tb) is one of the earliest human diseases which still is considered a public health problem. both genetic and environmental factors may contribute the susceptibility to tuberculosis. objectives akt is a serine/threonine kinase that has an important role in several cellular processes such as cell cycle control, cell survival, and cellular immigration. the akt signaling p...
