Background and purpose: Nowadays, multi-drug regimens or combination therapy are new approaches in cancer treatment that combine two or several therapeutic agents. Combination therapy aims at improving the therapeutic efficacy of anticancer drugs while reducing toxicity and preventing drug resistance. The aim of this study was to determine the synergistic effect of combined clarithromycin and d...
Lung cancer remains one of the most common cancer-associated mortalities worldwide, and platinum-based doublet chemotherapies are recommended as the first‑line treatment for advanced non‑small cell lung cancer (NSCLC). However, the frequent development of multidrug resistance, to cisplatin regimens in particular, is a major cause of chemotherapy failure in patients with aggressive NSCLC. Wnt/β‑...
Background and purpose: In most cases, drugs used for chemotherapy are ineffective and have unpleasant side-effects. This has made scientists to find more effective drugs with less toxicity. Lagenaria siceraria is an important medicinal plant in the world and anti-tumoral activity of Lagenaria species has been reported in some studies. This study was designed to evaluate the anti-tumoral effect...
Runx3, a member of Runt-related transcription factor (Runx) proteins with tumor suppressor effect, is a tissue–restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. In the present study, exogenous Run3 was transiently expressed in AGS (human gastric adenocarcinoma), with undetectable Runx3 protein and in A549 (human lung carc...

Chemotherapy resistance frequently drives tumour progression. However, the underlying molecular mechanisms are poorly characterized. In this study, we explored miR-137's role in the chemosensitivity of lung cancer. We found that the expression level of miR-137 is down-regulated in the human lung cancer tissues and the resistant cells strains: A549/paclitaxel(A549/PTX) and A549/cisplatin (A549/C...
Gefitinib induces lung cancer cell autophagy and apoptosis via blockade of the PI3K/AKT/mTOR pathway
Gefitinib is a selective inhibitor of the tyrosine kinase epidermal growth factor receptor, which inhibits tumor pathogenesis, metastasis and angiogenesis, as well as promoting apoptosis. Therefore, gefitinib presents an effective drug for the targeted therapy of lung cancer. However, the underlying mechanisms by which gefitinib induces lung cancer cell death remain unclear. To investigate the ...
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...
Lung cancer is the leading cause of cancer-related mortality worldwide. Most lung patients with brain metastases have very poor prognosis. The most common type from human adenocarcinoma. Although cyclin-dependent kinase (CDK) 9 has an established pathogenic role in various cancers, its function metastasis remains poorly defined. We A549 BrM3 cell line a parental (K-rasG12S). And investigated ex...
Lung cancer is a leading cause of cancer-associated mortality worldwide. The cisplatin (DDP)‑based chemotherapy remains the foundation of treatment for the majority of patients affected by advanced non‑small cell lung cancer (NSCLC). However, DDP‑resistance limits the clinical utility of this drug in patients with advanced NSCLC. The aim of the present study was to investigate the inhibitory ef...
