objective we have previously shown that rose bengal (rb) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. to clarify rb-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ros) were studied in melanoma cells. material and methods human melanoma cell lines, me 4405 and sk-mel-28 were cultured in dmem m...

objective(s):pharmacological studies showed that the extracts of jin yin hua and its active constituents have lipid lowering, antipyretic, hepatoprotective, cytoprotective, antimicrobial, antibiotic, antioxidative, antiviral, and anti-inflammatory effects. the purpose of the present study was to investigate the protective effects of caffeoylquinic acids (cqas) from jin yin hua against hydrogen ...

Cellular effects of ethanol in YD-15 tongue carcinoma cells were assessed by MTT assay, caspase activity assay, Western blotting and flow cytometry. Ethanol inhibited the growth and proliferation of YD-15 cells in a dose- and time-dependent manner in an MTT assay. The effects of ethanol on cell cycle control at low percent range of ethanol concentration (0 to 1.5%), the condition not inducing Y...

OBJECTIVE To investigate whether nicotine-induced testicular toxicity involves the induction of apoptosis in Leydig cells. DESIGN Cell study using cells of the TM3 cell line derived from mouse Leydig cells. SETTING Academic research laboratory. INTERVENTION(S) Morphological and biochemical analyses for the detection of apoptosis. MAIN OUTCOME MEASURE(S) The effect of nicotine on the occ...

Introduction: Previous studies have proven that secretory materials of mesenchymal stem cells (MSCs) (secretome) remedial properties. Objectives: The main goal this study was to evaluate the effects secretome adipose-derived MSCs on growth and apoptosis in anaplastic thyroid carcinoma (ATC) C-643 cells. Materials Methods: Initially, were exposed 25 50 μg/mL (ADSCs) for 24 48 hours, proliferatio...

BACKGROUND Iron is essential for cell proliferation and viability. It has been reported that iron depletion by a chelator inhibits proliferation of some cancer cells. Deferasirox is a new oral iron chelator, and a few reports have described its effects on lymphoma cells. The goal of this study was to determine the anticancer effects of deferasirox in malignant lymphoma cell lines. METHODS Thr...

This paper describes a label-free assay for measuring endogenous caspase protease activities in cell lysates. The assay format, termed SAMDI-MS (self-assembled monolayers for matrix assisted laser desorption ionization time-of-flight mass spectrometry), is based on the enzymatic modification of peptides immobilized to monolayer substrates, followed by direct detection of the products with mass ...

Human prostatic stromal myofibroblasts have been shown to be related to lower urinary tract symptoms (LUTS) in aging men. Devazepide, also known as a nonpeptide antagonist of CCK receptor, has been found to inhibit the proliferation in tumor cells. Here, we aim to investigate the effects of Devazepide on growth and contraction ability in human prostatic stromal WPMY-1 myofibroblasts. Human pros...

BACKGROUND Soluble eggshell membrane protein (SEP) has been proved to hold the antioxidant activity. The functional role of SEP on cardioprotection was investigated in vivo and in vitro. METHODS Rats and cardiomyocytes were pretreated with SP2, a hydrolysate attained from SEP, and then subjected to ischemia/reperfusion (I/R) or hypoxia/reoxygenation (H/R) and hydrogen peroxide, respectively. ...

BACKGROUND We have previously reported that anti-death receptor 5 (DR5) monoclonal antibody (mAb) is therapeutically effective in the treatment of rheumatoid arthritis (RA) in a collagen-induced arthritis rat model. However, the molecular mechanism and the effect of anti-DR5 mAb on proapoptotic genes and cytokine secretion in the human fibroblast-like synovial cells (FLS) requires further clari...
