The cytotoxicity of berberine on C6 rat glioma cells indicated that berberine induced morphological changes and caused cell death through G2/M arrest and apoptosis. While undergoing apoptosis, there was a remarkable accumulation of G2/M cells with the upregulatoin of Wee1 but it also inhibited cyclin B, CDK1 and Cdc25c that led to G2/M arrest. Along with cytotoxicity in C6 cells, several apopto...

BACKGROUND Arrest of the cell cycle in G2 phase following DNA damage helps protect cell viability by allowing time for DNA repair before entry into mitosis (M phase). Abrogation of G2 arrest sensitizes cells to the effects of DNA-damaging agents. UCN-01 (7-hydroxystaurosporine), a protein kinase C inhibitor that may block G2 checkpoint regulation, has been reported to enhance the cytotoxicity o...

Background: The aim of the study was to determine mechanism Moringa oleifera-induced apoptosis in HeLa cells. cells over-express cyclin E and B1, abrogate G0-G1 G2-M cell cycle arrest, promoting tumorigenesis. Cyclin E, E2F1 telomerase expression, caspase-3 -7 activation were assessed after 24-treatment with M. oleifera leaf fractions. Material methods: Apoptosis through caspase-7 determined qu...


 Purpose: To investigate the anticancer effect of glutinol on OVACAR3 human ovarian cancer cells, and to elucidate underlying molecular mechanisms.
 Methods: Cell viability was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. cycle distribution, reactive oxygen species (ROS) mitochondrial membrane potential were measured via flow cytometry, ...

introduction: an effective vaccine against hcv infection is not available. the non-structural protein 3 (ns3) of the virus as an important immunogenic candidate has been utilized in various modules. nanostructured polymers have been recently used for efficient vaccine and drug delivery. the aim of the current study was the synthesis of rns3-g2 conjugate and preliminary evaluation of its immunog...

Abstract Background and Aims Kidney transplantation is the only curative treatment for chronic kidney failure that allows to restaure a normal quality of life patients. In case abnormalities lower urinary tract, there risk recurrence renal due urodynamic disturbances. The objective our study analyze profile transplanted patients with their impact on graft. Method Our was conducted within Nephro...

Aims: Metabolic syndrome is a table of abdominal diseases characterized by insulin resistance, obesity, dyslipidemia, and hypertension, it serious risk factor for the development cardiovascular diseases. The purpose this study was to understand how metabolic causes change in myostatin levels, if swimming exercise have protective therapeutic effects fructose mediated model regulating serum level...

BACKGROUND Hydrogen peroxide (H(2)O(2)) is a common reactive oxygen intermediate generated by various forms of oxidative stress. AIM The aim of this study was to investigate the DNA damage capacity of H(2)O(2) in HepG2 cells. METHODS Cells were treated with H(2)O(2) at concentrations of 25 µM or 50 µM for 5 min, 30 min, 40 min, 1 h, or 24 h in parallel. The extent of DNA damage was assessed...

The aim of the present study was to evaluate the antitumor effects of the curcumin analogue GL63 on radioresistant nasopharyngeal carcinoma (NPC) CNE2R cells and parental CNE2 cells. The cell viability and proliferation of NPC cells were detected by MTT assay and colony formation assay. The suppressive effect on tumor growth was examined using in vivo subcutaneously inoculated NPC tumor models ...

BACKGROUND Lung cancers are leading causes of cancer death, and Rumex japonicus has been traditionally used in folk medicine as anti-microorganic, anti-inflammatory and anti-tumor agents. This study was designed to investigate the anti-proliferative activity of physcion 8-O-β-glucopyranoside (PG) isolated from Rumex japonicus Houtt. on A549 cell lines. METHODS In our present study, PG was iso...
