Background: Rosmarinic acid (RA) is a natural phenolic compound that acts as Fyn inhibitor by 53 homology modeling of the human structure. Therefore, apoptosis mechanism related to NF-κB signaling pathway induced RA in HepG2 was investigated. Methods: The cell growth, apoptosis, and proliferation regulated various concentrations were studied. proteins expression MMP-2, MMP-9, PI3K, AKT, NF-κB, ...

BACKGROUND Sorbus rufopilosa, a tsema rowan, is a species of the small ornamental trees in the genus Sorbus and the family Rosaceae found in East Asia. The bioactivities of S. rufopilosa have not yet been fully determined. The objective of this study is to evaluate the antioxidant and anticancer effects of ethanol extract of S. rufopilosa (EESR) and to determine the molecular mechanism of its a...

objective: azadirachta indica (neem) has been used traditionally for many centuries. some impressive therapeutic qualities have been discovered. however, the therapeutic effect of neem leaf extract in 4t1 breast cancer has not been documented. the purpose of the present study is to investigate the therapeutic effect of ethanolic neem leaf extract in an in vivo 4t1 breast cancer model in mice. m...

The aim of this study was to examine the tempo-spatial expression of low-affinity neurotrophin receptor p75, or p75(NTR), and its role in the induction of retinal ganglion cell (RGC) apoptosis in the rat retina during development. The cellular distribution of p75 in the retina was demonstrated with immunohistochemistry and double-immunofluorescent staining. Apoptosis in the developing rat retin...

Cytokines mediate pancreatic islet beta-cell apoptosis and necrosis, leading to loss of insulin secretory capacity and type 1 diabetes mellitus. The cytokines, IL-1beta and interferon-gamma, induced terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) staining of rat islet cells within 48 h by about 25-30%, indicative of apoptosis and/or necrosis. S...

Abstract Background Secreted frizzled-related protein 5 (SFRP5) is an endogenous inhibitor of Wnt5a (wingless-type family member 5a), which has been implicated in anti-inflammatory response. In this study, we aimed to investigate whether SFRP5 could protect chondrocytes against LPS-induced inflammation and apoptosis. Methods ATDC5 cells that overexpressed with or not were challenged LPS observe...

Introduction: Magnetic fluid hyperthermia (MFH) is a promising therapeutic method in cancer therapy with using magnetic nanoparticles (NPs). In this study, we assessed the effect of MFH on mechanisms of cell death in murine breast cancer cell line (MC4-L2) and also the treatment of breast tumor in BALB/C mice using four generation dendrimer coated iron oxide nanoparticles (G4@I...

Chemoresistance is the main cause of treatment failure in advanced colorectal cancer (CRC). However, molecular mechanisms underlying this phenomenon remain to be elucidated. In a previous work we identified low levels of PKM2 as a putative oxaliplatin-resistance marker in HT29 CRC cell lines and also in patients. In order to assess how PKM2 influences oxaliplatin response in CRC cells, we silen...

Ponicidin is a diterpenoid extracted from the Chinese herb Isodon adenolomus, which has been reported as a therapeutic cytotoxic drug that may be used to treat various types of human cancer. The present study aimed to determine the antitumor effects of ponicidin, and to investigate its underlying mechanisms in colorectal cancer. The HT29 colorectal cancer cell line was used to detect the cytoto...
