A Simple, Reproducible Procedure for Chemiluminescent Western Blot Quantification.

Western blotting is a universally used technique to identify specific proteins from a heterogeneous and complex mixture. However, there is no clear and common procedure to quantify the results obtained, resulting in variations due to the different software and protocols used in each laboratory. Here, we have developed a procedure based on the increase in chemiluminescent signal to obtain a representative value for each band to be quantified.

ARMS/Kidins220 and synembryn-B levels regulate NGF-mediated secretion.

Proper development of the nervous system requires a temporally and spatially orchestrated set of events including differentiation, synapse formation and neurotransmission. Nerve growth factor (NGF) acting through the TrkA neurotrophin receptor (also known as NTRK1) regulates many of these events. However, the molecular mechanisms responsible for NGF-regulated secretion are not completely understood.

Infection Exposure is a Causal Factor in B-cell Precursor Acute Lymphoblastic Leukemia as a Result of Pax5-Inherited Susceptibility.

Unlabelled: Earlier in the past century, infections were regarded as the most likely cause of childhood B-cell precursor acute lymphoblastic leukemia (pB-ALL). However, there is a lack of relevant biologic evidence supporting this hypothesis. We present in vivo genetic evidence mechanistically connecting inherited susceptibility to pB-ALL and postnatal infections by showing that pB-ALL was initiated in Pax5 heterozygous mice only when they were exposed to common pathogens.

Post-transcriptional Modifications Contribute to the Upregulation of Cyclin D2 in Multiple Myeloma.

Purpose: Dysregulation of one of the three D-cyclin genes has been observed in virtually all multiple myeloma tumors. The mechanisms by which CCND2 is upregulated in a set of multiple myeloma are not completely deciphered. We investigated the role of post-transcriptional regulation through the interaction between miRNAs and their binding sites at 3'UTR in CCND2 overexpression in multiple myeloma.

Factors influencing malignant evolution and long-term survival in solitary fibrous tumours of the pleura.

Solitary pleuro-pulmonary fibrous tumours are relatively uncommon neoplasms that are difficult to manage therapeutically and which, cytogenetically, have been poorly studied. The aim of the present work was to analyse the characteristics of a series of consecutive operated solitary pleural fibrous tumours in an attempt to discover a malignant pattern of evolution. This was a retrospective observational study of 19 cases.
