Melanoma differentiation associated gene-7 (mda-7): a novel anti-tumor gene for cancer gene therapy.
BACKGROUND The mda-7 gene (melanoma differentiation associated gene-7) is a novel tumor suppressor gene. The anti-proliferative activity of MDA-7 has been previously reported. In this report, we analyze the anti-tumor efficacy of Ad-mda7 in a broad spectrum of cancer lines. MATERIALS AND METHODS Ad-mda7-transduced cancer or normal cell lines were assayed for cell proliferation (tritiated thym...
Hepatocellular carcinoma (HCC) accounts for a proportion of cancer-associated mortalities worldwide. Hepatitis B virus (HBV) infection is a major cause of HCC in China. Thapsigargin (TG) is a potential antitumor prodrug, eliciting endoplasmic reticulum (ER) stress via the inhibition of the ER calcium pump, effectively inducing apoptosis. The present study therefore examined the role of HBV in T...
background: breast cancer is the most common diagnosed cancer among women in the world. snail1 plays a role in the development of the invasive phenotypes of cancer, neural cell differentiation, cell division and apoptosis in tumor cells. traces of snail1 in metastasis of breast cancer to bone are observed. the aim of this study was to investigate the effect of specific snail1 sirnas on the prol...
The development of drugs that selectively kill oral cancer cells but are less harmful to normal cells still provide several challenges. In this study, the antioral cancer effects of tenuifolide B (TFB), extracted from the stem of the plant Cinnamomum tenuifolium are evaluated in terms of their effects on cancer cell viability, cell cycle analysis, apoptosis, oxidative stress, and DNA damage. Ce...
Cigarette smoke-induced apoptosis of vascular endothelial cells contributes to the pathogenesis of chronic obstructive pulmonary disease. However, the mechanisms responsible for endothelial apoptosis remain poorly understood. We conducted an in vitro study to investigate whether DNA methylation is involved in smoking-induced endothelial apoptosis. Human umbilical vascular endothelial cells (HUV...
To determine the effect of hyperosmolarity on cell survival/apoptosis of conjunctival epithelial cells and evaluate the possible role of IL6, Wong-Kilbourne derivative of Chang conjunctival cell line (WKD) was used in this study. Confluent cells were incubated under different osmolarity (290 mOsm and 500 mOsm) with or without neutralizing IL6 antibody (50 ng/mL). The expression of IL6 level was...
Considering the necessity of an individual choice of cytostatic drugs for patients with cancer disease and tumor cells' resistance to these compounds, their ability to induction of apoptosis should be investigated. The aim of this study was to determine the influence of dacarbazine (DTIC) on morphology and kinetics of proliferation of B16 and Cloudman S91 cells. It is important to determine the...
Various anticancer drugs cause mitochondrial perturbations in association with apoptosis. Here we investigated the involvement of caspase- and Bcl-2-dependent pathways in doxorubicin-induced mitochondrial perturbations and apoptosis. For this purpose, we set up a novel three-color flow cytometric assay using rhodamine 123, annexin V-allophycocyanin, and propidium iodide to assess the involvemen...
Recent studies in our laboratory indicated that oxidative stress plays a key role in arsenic trioxide (ATO)-induced cytotoxicity in human cancer cells. In the present investigation, we used human hepatocellular carcinoma (HepG2) cells as a model to determine whether arsenic induced DNA damage and apoptosis is mediated through oxidative stress. To achieve this goal, oxidative stress biomarkers w...
BACKGROUND Hydroxychavicol (HCH), a constituent of Piper betle leaf has been reported to exert anti-leukemic activity through induction of reactive oxygen species (ROS). The aim of the study is to optimize the oxidative stress -induced chronic myeloid leukemic (CML) cell death by combining glutathione synthesis inhibitor, buthionine sulfoximine (BSO) with HCH and studying the underlying mechani...
