In analyzing the proteome using mass spectrometry, the mass values help identify the molecules, and the intensities help quantify them, relative to their abundance in other samples. Peptides that are shared across different protein sequences are typically discarded as being uninformative w.r.t each of the parent proteins. In this paper, we investigate the(More)
microRNAs (miRNA) play important roles in regulating immunity. Here we utilize the systems biology approach to predict the regulatory network of miRNAs among the most down-regulated genes by the lipopolysaccharides (LPS) treatment in the macrophage RAW267.4 cell line. We combine the proteome and transcriptome data sets to define 200 target genes that are(More)
UNLABELLED Increase in the world population has called for the increased demand for agricultural productivity. Traditional methods to augment crop and animal production are facing exacerbating pressures in keeping up with population growth. This challenge has in turn led to the transformational change in the use of biotechnology tools to meet increased(More)
In mass spectrometry-based protein quantification, peptides that are shared across different protein sequences are often discarded as being uninformative with respect to each of the parent proteins. We investigate the use of shared peptides which are ubiquitous (~50% of peptides) in mass spectrometric data-sets for accurate protein identification and(More)
Fibrosis is a pervasive disease in which the excessive deposition of extracellular matrix (ECM) compromises tissue function. Although the underlying mechanisms are mostly unknown, matrix stiffness is increasingly appreciated as a contributor to fibrosis rather than merely a manifestation of the disease. Here we show that the loss of Fibulin-5, an elastic(More)
This article draws on the evidence gathered from a corporate social responsibility (CSR) research project in the area of global information technology (IT) outsourcing to examine the impact of liminality. IT outsourcing offers a novel context to study this phenomena, as it operates across the boundaries of both firm and country. The case study focuses on(More)
Plants have evolved tightly regulated signaling networks to respond and adapt to environmental perturbations, but the nature of the signaling hub(s) involved have remained an enigma. We have previously established that methylerythritol cyclodiphosphate (MEcPP), a precursor of plastidial isoprenoids and a stress-specific retrograde signaling metabolite,(More)
Eukaryotic RNA polymerase II contains a C-terminal repeated domain (CTD) consisting of 52 consensus heptad repeats of Y1S2P3T4S5P6S7 that mediate interactions with many cellular proteins to regulate transcription elongation, RNA processing and chromatin structure. A number of CTD-binding proteins have been identified and the crystal structures of several(More)
