backgroud: protein-protein interaction, plays a key role in signal transduction in signaling pathways. different approaches are used for prediction of these interactions including experimental and computational approaches. in conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins interact which ca...

background and objectives: silymarin is a unique flavonoid complex with documented hepatoprotective properties. silybum  marianum hairy root culture as a source for producing silymarin has been an important strategy for study the cell signaling pathway. in the present investigation trichoderma strains- silybum marianum hairy root cultures interactions have been studied. methods: the effects of ...

in biotechnology has been concentrated to review alternative routes for the production of natural compounds. plant cell culture systems are viable alternatives for the production of secondary metabolites that are of commercial importance in food and pharmaceutical industries. however, relatively very few cultures synthesize these compounds over extended periods in amounts comparable to those fo...

punica granatum (pg), commonly known as pomegranate (pg), is a member of the monogeneric family, punicaceae, and is mainly found in iran which is considered to be its primary centre of origin. pg and its chemical components possess various pharmacological and toxicological properties including antioxidant, anti-inflammatory (by inhibiting pro-inflammatory cytokines), anti-cancer and anti-angiog...

background: the wnt/β- the wnt/β-catenin signaling pathway is involved in many developmental processes in both fetal and adult life; its abnormalities can lead to disorders including several types of cancers and malfunction of specific cells and tissues in both animals and humans. its role in reproductive processes has been proven. objective: this study was designed to evaluate the expression o...

inflammatory condition is the consequence of defensive mechanism of immune system against viral and bacterial infection, tissue injury, uv radiation, stress and etc. persistently acute inflammation leads to chronic phase which is characterized by production of pro-inflammatory mediators from t cells. these molecules (e.g. il-6, tnf-α, il-1β and il-17) are mostly pleiotropic cytokines involved i...

It is estimated that up to 20% of all types of human cancers worldwide are attributed to viruses. The genome of oncogenic viruses carries genes that have protein products that act as oncoproteins in cell proliferation and transformation. The modulation of cell cycle control mechanisms, cellular regulatory and signaling pathways by oncogenic viruses, plays an important role in viral carcinogenes...

The phosphoinositide-3-kinase/Akt (PI3K/AKT) signaling pathway is crucial for Sertoli cell development and completing spermatogenesis. Its main role to promote proliferation inhibit apoptosis. Many factors activate the PI3K/AKT pathway, like hormones, such as follicle stimulating hormone (FSH), androgen, estrogen, insulin name a few. of these have receptors inside or on surface cells (SCs). Thi...

The growth hormone receptor (GHR), although most well known for regulating growth, has many other important biological functions including regulating metabolism and controlling physiological processes related to the hepatobiliary, cardiovascular, renal, gastrointestinal, and reproductive systems. In addition, growth hormone signaling is an important regulator of aging and plays a significant ro...
