Abstract The effects observed under near-infrared laser irradiation of mammalian cells have been demonstrated to depend a large extent on the type source. In our experiments, we measured concentration reactive oxygen species in cell cultures different origin (rodent and human, cancerous non-cancerous) exposed radiation low-level lasers at 1265 nm. Surprisingly, narrowband occur be more pronounc...
It is aimed to evaluate the actual anti-cancerous effects of metformin on cancer cells in hypoxic condition. Non-cancerous cells (HEK293) and cancer cells (MCF-7) were cultured in both hypoxia and normoxia conditions and treated with different concentrations of metformin. The proliferation, apoptosis, and necrosis rate were assessed using MTT test and Annexin V assay. The S6K1 phosphorylation w...
BACKGROUND MicroRNA-106b (miR-106b) is thought to be an oncogenic microRNA that promotes tumor growth and metastasis. The potential predictive value of miR-106b was studied in colonic cancer patients. METHODS The expression of miR-106b was examined in 180 colonic cancer cases using in situ hybridization (ISH) technique and was evaluated semi-quantitatively by examining the staining index. The...
Heparan sulfate fractions were isolated from three normal human livers and three cancerous human liver tissues, and their polyanionic properties were examined using electrophoresis, sequential partition fractionation, and chemical analyses. More than 60% of total glycosaminoglycans from normal human liver and about 30% from cancerous liver tissue were found to be heparan sulfate from their resi...
Background and study aims With magnifying narrow-band imaging (M-NBI) of the gastric mucosa, a characteristic demarcation line (DL) is occasionally found in non-cancerous depressed lesions. This DL forms multiple convex shapes along the edge of the epithelia of surrounding mucosa. We have termed this novel finding a multiple convex DL (MCDL). In this study, we clarified the prevalence of an MC...
We have previously reported hepcidin and ferritin increases in the plasma of breast cancer patients, but not in patients with benign breast disease. We hypothesized that these differences in systemic iron homeostasis may reflect alterations in different iron-related proteins also play a key biochemical and regulatory role in breast cancer. Thus, here we explored the expression of a bundle of mo...
IL-10 is an 18-kd polypeptide that has been shown to be secreted by multiple cell types, including T and B cells, monocytes and some human tumors. However, which cell population is responsible for the elevated IL-10 levels in the serum and ascites of ovarian cancer patients, whether ovarian carcinoma cells produce IL-10, and how IL-10 influences the development and progression of ovarian carcin...
