Objective(s): Naringin has been reported to regulate bone metabolism. However, its effect on osteogenesis remains unclear. The aim was to investigate the effect of naringin on osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) through the activation of the ERK signaling pathway in osteogenic differentiation. Materials and Methods: Annexin V-FITC assay and MTT assay ...
In this study, the cytotoxic effects of aqueous and ethanolic extracts of Sedum album L. on human stomach cancer cell line (AGS) and breast cancer cell line (MCF-7) were evaluated by MTT, BrdU and TUNEL assays. The results demonstrated that both extracts had antiproliferative and apoptotic effects in a dose-dependent manner. The MTT assay data revealed that the AGS cell underwent more cytotoxic...
dried aceton-chloroform extract of aerial parts of euphorbia spinidens bornm. ex prokh. endemic to iran, yielded two new triterpenoids, lup-20(29)-ene-33, 28 diol commonly known as betulin and (3β,23e)-cycloarta-23-ene-3,25-diol. the structures of the isolated compounds were elucidated by 13 c- and 1 h-nmr as well as 2d-nmr, ir and by the aid of mass fragmentation pattern. in phagocyte chemilum...
Background & Objective: Dendritic cell (DC) is as a key cell in activation of immune response against microbes and disease. Therefore, the effect of recombinant exotoxin A of Pseudomonas aeruginosa on the maturity and the activation of DCs was evaluated in this study. Materials & Methods: Recombinant exotoxin A was produced from Pseudomonas aeruginosa DNA. MTT assay was used to evaluate ...
Abstract BACKGROUND Glioblastoma (GBM) is one of the most malignant primary brain tumors. Despite development treatment, prognosis GBM still poor. Here, we identified lomerizine, a prophylactic drug for migraine, as potential anti-GBM from thousands existing compounds. We investigated its therapeutic effects both in vitro and vivo with purpose repositioning. Materials method: Human patient-deri...
Introduction: In this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. Methods: Bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μM of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan bl...
Objective : The anti-tumor effect of the beta-adrenergic receptor antagonist propranolol in breast cancer is well known; however, its activity glioblastoma not well-evaluated. Notch-Hes pathway known to regulate cell differentiation, proliferation, and apoptosis. We investigated human lines, role Notch Hes signaling this process.Methods performed immunohistochemical staining on 31 surgically re...
Background: Probiotic microorganisms are living normal flora of human body that have nutritional value and health benefits when administered in adequate amounts. The health benefits include prevention of bacterial diarrhea, skin eczema and recently understood, prevention and control of various cancers, as well. Different mechanisms such as stimulating the immune system, modifying the compositio...
Objective(s):Intermittent hypoxia (IH), caused by obstructive sleep apnea (OSA), could cause hippocampus or neuron damage through multiple signaling pathways, while the underlying mechanisms are still unclear. Thus, the present study aimed to explore the effect of IH on the biological functions of microglia cells. Materials and Methods:Cell proliferation of BV2 cells after exposure to IH were o...
Cryptocarya pulchrinervia is an Indonesian indigenous plant that grows in Sumatra, Kalimantan and Papua. One of the new compounds extracted from this was cryptobrachytone C, which known to be cytotoxic against cancer cells Murine leukemia P388 with IC50 10.52 ?M. In study, cytotoxicity anticancer properties C on proliferation, apoptosis, migration clone formation MCF-7 T47D breast cell lines we...
