EGFR Exon 18 Mutations in Lung Cancer: Molecular Predictors of Augmented Sensitivity to Afatinib or Neratinib as Compared with First- or Third-Generation TKIs

2119 views | Feb 05 2017

Kobayashi Y, et al.’‘s result shows that’Lung cancers harboring exon 18 mutations should not be overlooked in clinical practice. These cases can be best treated with afatinib or neratinib, although the currently available in vitro diagnostic kits cannot detect all exon 18 mutations [Read the Full Post]

Ph-like ALL-related novel fusion kinase ATF7IP-PDGFRB exhibits high sensitivity to tyrosine kinase inhibitors in murine cells.

Ishibashi T, et al.'s observations suggest the therapeutic importance of tyrosine kinase inhibitors and possibly MEK inhibitor for a subset of BCP-ALL harboring PDGFRB-related fusion kinases. [Read the Full Post]

Nitric oxide plays a dual role in the oxidative injury of cultured rat microglia but not astroglia

0 views | Feb 04 2017

Wang JY et al. suggested that NO exhibits a concentration-dependent dual action of weakening or enhancing oxidative injury in mixed glia, particularly microglia. [Read the Full Post]

Wnt/b-Catenin-Signaling and the Formation of M€uller Glia-Derived Progenitors in the Chick Retina

1478 views | Feb 04 2017

Gallina D, et al 's findings indicate that Wnt-signaling is part of a network initiated by FGF2/MAPK or retinal damage, and activation of canonical Wnt-signaling is required for the formation of proliferating MGPCs. [Read the Full Post]

Signaling through the Phosphatidylinositol 3-Kinase (PI3K)/ Mammalian Target of Rapamycin (mTOR) Axis is Responsible for Aerobic Glycolysis mediated by Glucose Transporter in Epidermal Growth Factor Receptor (EGFR)-mutated Lung Adenocarcinoma
