AbstractMeosthelioma is a neoplasm of the pleura that currently incurable by conventional therapies. Previously, we demonstrated mesothelioma overexpresses BCL-XL, an anti-apoptotic member BCL-2 family. In addition, have shown down-regulation BCL-XL using antisense oligonucleotide engenders apoptotic cell death in vitro and vivo. The purpose this study to evaluate efficacy bcl2/bcl-xl inhibitor, 2-methoxy antimycin A3, inducing apoptosis increasing chemo-sensitivity Several bcl-xl...

Bortezomib, a proteasome-specific inhibitor, has emerged as promising cancer therapeutic agent. However, development of resistance to bortezomib may pose challenge effective anticancer therapy. Therefore, characterization cellular mechanisms involved in and strategies overcome this represent important steps the advancement bortezomib-mediated therapy.The present study reports I-45-BTZ-R, bortezomib-resistant cell line, from bortezomib-sensitive mesothelioma line I-45. I-45-BTZ-R cells showed...

Bcl-xL functions as a dominant regulator of apoptotic cell death and is implicated in chemotherapeutic resistance malignant pleural mesothelioma (MPM). Mesothelioma lines demonstrate increasing levels resistant clones are selected vitro. Moreover, upon introduction antisense oligonucleotides specific to mRNA, MPM cells sensitized agents. Here we describe the therapeutic effects novel combination therapy, oligonucleotide (ASO 15999) cisplatin, on vitro vivo; addition, efficacy ASO 15999...

Streptococcus pneumoniae open reading frame SP0082 encodes a surface protein that contains four copies of novel conserved repeat domain bears no significant sequence similarity to proteins known function. Homologous sequences from other streptococci contain two six these repeats, designated the SSURE (streptococcal repeat) domain. To investigate functional role(s) this domain, third has been expressed in Escherichia coli, purified homogeneity and characterized by biochemical immunological...

Streptococcus pneumoniae open reading frame SP1492 encodes a surface protein that contains novel conserved domain similar to the repeated fragments of mucin-binding proteins from lactobacilli and lactococci. To investigate functional role(s) this its potential adhesive properties, surface-exposed region was expressed in Escherichia coli, purified homogeneity, partially characterized by biophysical immunological methods. Circular dichroism sedimentation measurements confirmed is an all-beta...

Pneumococcal surface protein A (PspA) is an antigenic variable vaccine candidate of Streptococcus pneumoniae. Epitope similarities between PspA from the American strain Rx1 and Norwegian clinical isolates were studied using specific monoclonal antibodies (mAbs) made against strains. Using recombinant PspA/Rx1 fragments immunoblotting epitopes for mAbs mapped to two regions amino acids, 1–67 67–236. The discovered visualized by modelling PspA:Fab part mAb in three dimensions. Flow cytometric...

Abstract Purpose of the Review Anemia in critically ill is both insidious and highly prevalent; has been implicated poor outcomes patients with recovering from critical illness. Patient-oriented approaches to blood management (PBM) are gaining momentum have widespread applications as a superior approach anemia. The volume publications pertaining PBM dramatically increased past 4 years, warranting further review emerging paradigms ICU. Recent Findings IV iron alone conjunction erythropoietin...
