Gefitinib inhibits invasive phenotype and epithelial-mesenchymal transition in drug-resistant NSCLC cells with MET amplification.

Despite the initial response, all patients with epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) eventually develop acquired resistance to EGFR tyrosine kinase inhibitors (TKIs).The EGFR-T790M secondary mutation is responsible for half of acquired resistance cases, while MET amplification has been associated with ac

Role of cellular NADP+/NADPH ratio in the acclimative mechanism of two common bean cultivars toward salt stress

This study is aimed to evaluate the adaptive mechanism in two common bean (Phaseolus vulgaris L.) cultivars, cv.Bronco and cv.Paulista subjected to different concentrations of NaCl (0, 25, ACCESSORIES SCARVES 50 and 75 mM).Salt treatments resulted in a significant decrease in the fresh and dry biomasses of shoots and roots as well as leaf relative

MAPK-activated protein kinase 2 is required for mouse meiotic spindle assembly and kinetochore-microtubule attachment.

MAPK-activated protein kinase 2 (MK2), a direct substrate of p38 MAPK, plays key roles in multiple physiological functions in mitosis.Here, we Placemats show for the first time the unique distribution pattern of MK2 in meiosis.Phospho-MK2 was localized on bipolar spindle minus ends and along the interstitial axes of homologous chromosomes extending
