Results: Mean patient age was 63 years old. Median prostate specific antigen at biopsy was 5.8 ng/ml and 90.1% of patients had a negative digital rectal examination. Of patients with low, moderate and high suspicion on magnetic resonance imaging 27.9%, 66.7% and 89.5% were diagnosed with cancer, respectively

(p < 0.0001). Magnetic resonance imaging/ultrasound fusion guided biopsy detected more cancer per core than standard 12-core transrectal ultrasound biopsy for all levels of suspicion on magnetic resonance imaging.

Conclusions: Prostate cancer localized on magnetic resonance imaging may be targeted using this novel magnetic resonance imaging/ultrasound fusion guided biopsy platform. Further research is needed to determine the role of this platform

in cancer detection, active surveillance and focal AMG510 cell line therapy, and to determine which patients may benefit.”
“Mutations in leucine-rich repeat kinase 2 (LRRK2) have been causally linked to neuronal cell death in Parkinson’s disease. LRRK2 expression has also been detected in B lymphocytes and macrophages, suggesting a role in immune responses. In the present study, we demonstrate that LRRK2 is expressed in primary microglial cells isolated from brains of adult mice. Moreover, lipopolysaccharide (LPS)activated microglial cells from mice overexpressing the Parkinson’s disease-linked LRRK2(R1441G) mutation exhibit increased expression and secretion of proinflammatory cytokines buy PX-478 compared with wild-type control microglia. Expression of the LPS receptor Toll-like receptor 4 (TLR4) and downstream signaling proteins did not differ between LRRK2(R1441G) transgenic microglia and wild-type controls. Consistently, conditioned medium from LPS-stimulated

LRRK2(R1441G) transgenic microglia induced significant cell death when added to neuronal cultures. These findings indicate that enhanced MK-0518 chemical structure neuroinflammation may contribute to neurodegeneration in Parkinson’s disease patients carrying LRRK2 mutations. (C) 2012 IBRO.

“The systematic sequencing of glioblastoma multiforme (GBM) genomes has identified the recurrent mutation of IDH1, a gene encoding NADP(+)-dependent isocitrate dehydrogenase 1 (IDH1) that catalyzes the oxidative decarboxylation of isocitrate yielding alpha-ketoglutarate (alpha-KG). Subsequent studies have confirmed recurrent IDH1 and IDH2 mutations in up to 70% of low-grade glioma and secondary GBM, as well as in 10% of acute myeloid leukemia (AML) cases. The heterozygous somatic mutations at arginine R132 (IDH1) and at R140 or R172 (IDH2) in the enzyme active site confer a gain of function to the enzymes, which can both produce the metabolite 2-hydroxyglutarate. This review surveys the prevalence of IDH mutations in cancer and explores current mechanistic understanding of IDH mutations with implications for diagnostic and therapeutic development for the treatment of gliomas and AML.
