The anti-cancer activity of resveratrol in human esophageal squamous cell carcinoma (ESCC) was investigated focusing on the role of autophagy and its effects on apoptotic cell death. We demonstrated that resveratrol inhibits ESCC cell growth in a dose-dependent manner by inducing cell cycle arrest at the sub-G1 phase and resulting in subsequent apoptosis.(More)
Resveratrol has many biological effects, including anti-tumor, antiviral activities, and vascular protection. Recent studies have suggested that resveratrol exert its antitumor effects through induction of autophagy by an unknown mechanism. In this study, we investigated the involvement of autophagy in resveratrol-induced cell death and its potential(More)
AIM The aim of this study was to investigate and evaluate the role of magnetic resonance (MR) diffusion kurtosis imaging (DKI) in characterizing breast lesions. MATERIALS AND METHODS One hundred and twenty-four lesions in 103 patients (mean age: 57 ± 14 years) were evaluated by MR DKI performed with 7 b-values of 0, 250, 500, 750, 1,000, 1,500, 2,000(More)
Arsenic and its derivatives are naturally occurring metalloid compounds widely distributed in the environment. Arsenics are known to cause cancers of the skin, liver, lung, kidney, and bladder. Although numerous carcinogenic pathways have been proposed, the exact molecular mechanisms remain to be delineated. To further characterize the role of oxidative(More)
Resveratrol (3,4',5-trihydroxy-trans-stilbene), one of secondary metabolites of low molecular weight present in plant, has various important biological effects. It can induce apoptosis in human leukemia cell types in vitro, although the mechanism is not fully understood. In the present study, we demonstrated reduced viability and DNA synthesis, as well as(More)
BACKGROUND AND OBJECTIVE Invasion and metastasis are the primary causes of death in patients with pulmonary carcinoma. The epidermal growth factor (EGF) stimulates A549 cells invasion greatly through activating ERK and PI3K-Akt signaling pathway. The aim of this study is to elucidate the inhibitory effect of Resveratrol on EGF-induced invasive ability of(More)
Chemokine (CC motif) ligand-2 (CCL2) is a member of C-C chemokine superfamily that contributes to inflammatory and fibrotic process. Studies in patients and experimental animals provide compelling evidence that increased CCL2 expression plays an important role in the development of fibroproliferative lung disease. The up-regulated CCL2 expression in(More)
The multipotent mouse F9 embryonic carcinoma cell is an ideal model system to investigate the mechanism of retinoic acid (RA) in cell differentiation and cell growth control and the biochemical basis of early embryonic development. We reported here a proteomics approach to study protein expression changes during the differentiation of F9 cells into the(More)
Resveratrol is a potential polyphenol drug used in cancer treatment. We examined the relationship between autophagy and apoptosis in RSV-treated non-small lung adenocarcinoma A549 cells. Resveratrol treatment increased autophagy and autophagy-mediated degradation of P62. Immunocytochemistry revealed P62 co-localized with Fas/Cav-1 complexes, known to induce(More)
microRNA regulation network is important for the cancer genetic heterogeneity. Relative to the increasing numbers of microRNA's targets identified, upstream regulatory mechanisms that control functional microRNAs are less well-documented. Here, we investigated the function of miR-31, a pleiotropically-acting microRNA, in esophageal squamous cell cancer(More)
