Immunohistochemical validation study of 15-gene biomarker panel predictive of benefit from adjuvant chemotherapy in resected non-small-cell lung cancer: analysis of JBR.10.

Objective: There are no validated approaches to predict benefit from adjuvant chemotherapy for resected patients with non-small-cell lung cancer (NSCLC). The aim of this study was to translate a 15-gene mRNA expression profile published by Zhu shown to be prognostic and predictive of benefit, into a readily applicable immunohistochemistry (IHC) panel.

Methods: For seven of the genes in the gene expression profile (GEP) for which suitable commercial antibodies were available, we semiquantitatively assessed the IHC expression and prognostic significance for 173 patients treated at the Saint John Regional Hospital (SJRH).

Delivery of Soluble Heme Oxygenase 1 Cell-Penetrating Peptide into Liver Cells in in vitro and ex vivo Models of Cold Ischemia.

Background/purpose: Liver transplantation is the treatment of choice in patients with end-stage liver disease. During liver transplantation, ischemia-reperfusion injury (IRI) occurs, which is an inevitable consequence of the transplantation process. To reduce the extent of cellular injury, one of the proteins that have been extensively investigated is heme oxygenase 1 (HO-1), which plays an important role in protecting the organs against IRI.

Cux2 activity defines a subpopulation of perinatal neurogenic progenitors in the hippocampus.

The hippocampus arises from the medial region of the subventricular (SVZ) within the telencephalon. It is one of two regions in the postnatal brain that harbors neural progenitors (NPs) capable of giving rise to new neurons. Neurogenesis in the hippocampus is restricted to the subgranular zone (SGZ) of the dentate gyrus (DG) where it contributes to the generation of granule cell layer (gcl) neurons.
