BACKGROUND To explore the effects of Osthole on the proliferation, cell cycle and apoptosis of human lung cancer A549 cells. METHODS Human lung cancer A549 cells were treated with Osthole at different concentrations. Cell proliferation was measured using the MTT assay. Cell cycle was evaluated using DNA flow cytometry analysis. Induction of apoptosis was determined by flow cytometry and fluor...

OBJECTIVE To evaluate the expression of ALDH1A1 in lung adenoma stem cells (LASCs) and maintenance of their stemness through the Notch pathway. METHODS LASCs (A549s) were isolated from lung adenoma cells (A549) and identified by their coexpression of CD133 and CD326 and their capacity formulti-directional differentiation. Expression of ALDH1A1 in A549 and A549s cells were evaluated by Real-ti...

Background and purpose: Cancer is one of the major health challenges in the world. The efficacy of current treatments is low but their side effects are high. Cold atmospheric plasma (CAP) is a new modality for cancer treatment. This study aimed to compare the cytotoxicity effect of CAP on the cell line models of common cancers and normal cells. Materials and methods: In this experimental study...

BACKGROUND Effective cancer chemotherapy remains an important issue in cancer treatment, and signal transducer and activator of transcription-3 (Stat3) activation leads to cellular resistance of anticancer agents. Polymers are ideal vectors to carry both chemotherapeutics and small interfering ribonucleic acid (siRNA) to enhance antitumor efficacy. In this paper, poly(lactic-co-glycolic acid) (...

Objective: Lung cancer is a leading cause of cancer-related death worldwide. Most lung cancers are nonsmall cell lung cancer (NSCLC). The overall survival of NSCLC patients with advanced stage or metastatic lesions remains very poor. Therefore, the development of novel treatments for NCSLC is clinically needed. Previous studies reported a relationship between calpain, a calcium-dependent intrac...

The aim of the present study was to investigate cobra neurotoxin (cobrotoxin) activity in A549 cell lines transplanted into nude mice, and to explore its molecular mechanism. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method was used to detect the growth inhibition rate of cobrotoxin in human lung A549 adenocarcinoma cells and HFL1 lung fibroblasts. Cell colony forma...

The utilization of tungsten disulfide (WS2) nanomaterials in distinct applications is raising due to their unique physico-chemical properties, such as low friction coefficient and high strength, which highlights the necessity study potential toxicological effects, increase environmental human exposure. aim this work was analyze commercially available aqueous dispersions monolayer (2D WS2) with ...

Purpose: To investigate anticancer effects of Momordica charantia L. (M. charantia) fruit and seed extracts on some cancer cell lines.
 Methods: Human lines, including lung (A549), breast (MCF-7), chronic myeloid leukemia (K562) T (Jurkat) were incubated with the (0 - 0.8 mg/mL) for 72 h. The cytotoxic determined using 3-(4,5-dimethylthiazol-2-yl)-2,5- dipenyltetrazolium bromide (MTT) assa...

Many studies are based on the hypothesis that recurrence and drug resistance in lung carcinoma are due to a subpopulation of cancer stem-like cells (CSLCs) in solid tumors. Therefore it is crucial to screen for and recognize lung CSLCs. In this study, we stimulated non-small cell lung cancer (NSCLC) A549 cells to display stem cell-like characteristics using a combination of five small molecule ...

Metabolic change in cancer cells by preferential production of energy through glycolysis is a well-documented characteristic of cancer. However, whether inhibition of glycolysis will enhance the efficacy of radiation therapy is a matter of debate. In this study which uses lung cancer as the model, we demonstrate that the improvement of radiotherapy by 2-deoxy-D-glucose (2DG) is p53-dependent. B...
