Since there are no studies on the reversal of multidrug resistance by curcumin in the human colorectal cancer cell line HCT-8/5-FU, our aim was to search for highly efficient reversal agents and investigate the underlying mechanisms of this reversal. The cytotoxic effects of curcumin and 5-FU on HCT-8 and HCT-8/5-FU cells and the reversal effects of 5-FU in combination with curcumin on HCT-8/5 ... more

We investigated the paracrine effects of bone marrow mesenchymal stem cells (BMSCs) on the proliferation, apoptosis, and alpha-actin-2 (ACTA2) expression of hepatic stellate cells (HSCs), and explored the possible mechanisms of hepatocyte growth factor (HGF). We established a co-culture system by culturing BMSCs on the upper layer and HSCs on the lower layer of a 6-well Transwell plate. Normal ... more

Breast cancer adversely affects the health status of women; therefore, the prevention and treatment of breast cancer is of critical importance. Lycopene is known to possess several biological effects such as removal of free radicals, alleviation of biological oxidative injury, and inhibition of tumor growth. In this study, we aimed to illustrate the effect of lycopene on tumor cell ... more

Previous studies have found that 1,25-dihydroxyvitamin D [1,25(OH)D or VD] exerts many biological effects, including the inhibition of cell proliferation and induction of apoptosis, but its mechanism of action remains unclear. The goal of our investigation was to explore the effects of 1,25(OH)D on the proliferation of cultured human mesangial cells and their expression of Ki67 in vitro, and ... more

Integral grape juice is extracted from the grape through processes that allow the retention of their natural composition. However, due to the severity of some processes, fruit juices can undergo changes in their quality. The present study evaluated the cytotoxic and mutagenic effects of integral grape juice by a cytokinesis-blocked micronucleus assay in Rattus norvegicus hepatoma cells (HTC) ... more

Human equilibrative nucleoside transporters (hENT) 1 and 2, encoded by SLC29A1 and SLC29A2, permit the bidirectional passage of nucleoside analogues into cells and may correlate with clinical responses to chemotherapy in patients with colorectal cancer (CRC). The purpose of this study was to evaluate the expression profiles of SLC29A1 and SLC29A2 in human cancer cell lines. Using quantitative ... more

The mRNA expression of cell adhesion molecule 1 (CADM1) and its clinicopathological significance in esophageal squamous cell carcinoma (ESCC) tissues were investigated. CADM1 mRNA and protein expression were detected in tissue samples from 50 patients with ESCC by reverse transcription-polymerase chain reaction (RT-PCR) and streptavidin-peroxidase (SP) immunohistochemistry; adjacent tissues ... more

The aim of this study was to explore the effect of aquaporin on the molecular mechanism of human diabetic myocardial cell apoptosis. The methylthiazolyle tetrazolium assay was used to detect the inhibitory effect of different concentrations of aquaporin on cell growth. The rate of aquaporin-induced myocardial cell apoptosis was detected by flow cytometric analysis of Annexin V-fluorescein ... more

We investigated the effect of propofol on the proliferation and viability of rat embryonic neural stem cells (rENSCs) and the potential mechanisms involved. rENSCs were isolated and cultured in vitro and treated with 1, 10, or 50 μM propofol, while the control group was treated with 0.1 μM dimethyl sulfoxide. The effect of propofol on the proliferation and viability of rENSCs was ... more

Stem cell therapy faces many problems including poor survival rates and low viability. Enhancing the biological functions of stem cells improves efficacy of therapies. Estrogen, whose levels are elevated during pregnancy, affects the properties of bone marrow mesenchymal stem cells. Evidence suggests that adipose-derived stem cells (ADSCs), which are a type of adult mesenchymal stem cells, can ... more
