While AS regulation enables

the production of the hundreds of thousands of types of proteins needed for the normal functioning of the human cell, it also presents many opportunities for the onset of cancer and other diseases. The AS process is known to be regulated by a group of serine/arginine rich (SR) proteins, heterogeneous nuclear ribonucleoproteins (hnRNPs), and small nuclear ribonucleoprotein (snRNP) particles through a complex assembly. Each gene-exon is regulated by one or multiple splicing regulators, from which one may hypothesize the existence of an alternative splicing regulatory network (SRN). The SRN contains a list of gene-exons, for each of which the factors that up/down regulate them are provided. Since defects in the SRN play key roles XAV 939 in human disease, a reconstruction of human SRN could be used to facilitate the design of diagnostic and therapeutic strategies. In SBI-0206965 concentration this paper, we present a methodology to automate genome-wide SRN reconstruction. We construct SRN based on an extensive correlation analysis of human exon expression microarray data, conventional gene expression microarray profiles, and an experimentally verified AS and transcriptional regulatory interaction training set. This SRN reconstruction methodology is demonstrated

and software (AutoNet) that automates the reconstruction of SRN is developed. A genome-wide SRN was constructed for normal human cells and an assessment of the reliability of each predicted interaction is provided.

“Functional magnetic resonance imaging (fMRI) was

used to investigate the dose-response relationship (sham, 100, 200, 1000 mu T) between a pulsed extremely low frequency magnetic field (ELFMF) and acute thermal pain on the dominant right hand. Forty-seven participants were recruited, and pulsed ELFMF was applied through the MRI gradient system using a novel technique. Regions of interest (ROIs) matching those of previous studies were examined for a potential dose response. Significant correlations between applied field strength and change in BOLD activity were found in the anterior cingulate and the ipsilateral insula, indicating that there might be either a dose response or a threshold effect of the ELFMF.

“The lengths of the hook structure of flagellar motors and of the needle of the injectosome are both carefully controlled, by apparently similar mechanisms. In this paper we propose a novel mechanism for this length control and develop a mathematical model of this process which shows excellent agreement with published data on hook lengths.
