To explore the reversal effect of Fuzheng oral liquid on anlotinib resistance in non-small cell lung cancer cells and its mechanism is objective study. 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide assay flow cytometric were performed to evaluate effects proliferation apoptotic cycles adenocarcinomic human alveolar basal epithelial line A549 cells, respectively. Western blot was...

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...

سرطان ریه مهم‌ترین عامل مرگ ناشی از سرطان در دنیا می‌باشد و از آن جایی که اغلب درمان‌های امروزی سرطان ناکارآمد و دارای عوارض جانبی زیادی هستند، لذا یافتن درمان موثر و جایگزین ضروری به نظر می‌رسد. گیاه گزنه با نام علمی Urtica dioica L. از تیره Urticaceae گیاهی چند ساله، علفی گلدار است که ارزش غذایی و دارویی بالایی دارد. لذا در پژوهش حاضر تاثیر سیتوتوکسیکی عصاره اتانولی برگ گیاه گزنه (Urtica dioi...

Exosomes derived from lung cancer cells confer cisplatin (DDP) resistance to other cancer cells. However, the underlying mechanism is still unknown. A549 resistance to DDP (A549/DDP) was established. Microarray was used to analyze microRNA (miRNA) expression profiles of A549 cells, A549/DDP cells, A549 exosomes, and A549/DDP exosomes. There was a strong correlation of miRNA profiles between exo...

Erlotinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, is an effective therapy for non-small cell lung cancer (NSCLC). However, resistance to erlotinib reduces its efficacy. To investigate the basis of erlotinib resistance, we isolated erlotinib-resistant human NSCLC A549 cells, termed A549/ER cells. The A549/ER cells were found to be resistant to erlotinib, as well as...

Multiple clinical and experimental studies have suggested that epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) may be effective at treating advanced non-small cell lung cancer (NSCLC), however, the molecular basis of primary resistance to EGFR-TKIs in NSCLC remains unclear. In the current study, the insulin-like growth factor 1 receptor (IGF-1R) gene in the gefitinib-res...

Lung cancer is a most common malignancy in both men and women. Studies have indicated that YAP gene was closely related to chemo-resistance of cancers. However, whether YAPS expression participates in the resistance of human lung cancer A549 cells to Taxol (TAX) remains unclear. The aim of this study is to investigate the role of YAP in the resistance of A549 cells to TAX. The sensitivity of ce...
