Our project is partially focused on insulin affecting four proteins associated with lung surfactant. Small and hydrophobic SP-B and S-PC help to spread and stabilize the surfactant layer while large and hydrophilic SP-A and SP-D participate in immune responses. A549 and H441 cell lines were used. It was observed using RealTime PCR that higher doses of insulin lead to decreased transcription of SP-B, SP-C, SP-D, and both isoforms of SP-A.

Sorting signals of tonoplast proteins and the pathway they follow through the endomembrane system are still poorly characterized. Using Brefeldin A (an inhibitor of the Golgi-mediated traffic) we showed that a Golgi-dependent pathway for tonoplast delivery may exist. Then we generated various chimeric TPK1-TPK4 fusions, exchanging various domains. We observed that the cytosolic, C-terminal domain of TPK1 is sufficient to re-direct the plasma membrane TPK4 to the tonoplast.

Although null p-values are assumed to be uniformly distributed in gene expression experiments, the actual distribution often deviates from the assumed distribution. This can incorrectly associate the biology of a geneset with cancer prognosis in geneset-based survival studies. To assess the implications of this, a geneset-based method was developed. This method empirically approximates the distribution of null p-values and tests whether predefined sets of biologically-related genes are associate

Reactome is a manually curated knowledgebase, created and peer-reviewed by experts in their field. Its robust data model describes life processes ranging from metabolism to signal transduction and the cell cycle. As of release 28, Reactome contains 3700 human proteins in 3200 reactions. Data is cross-referenced to publicly available web-based informatics resources. Reactome features the SkyPainter tool for analysis of high-throughput datasets, and the Mart query and data retrieval tool.

To examine the relationship between panic attack and suicide risk, we analyzed data from a representative epidemiological survey of 43,093 adults (NESARC) using logistic regression controlling for socio-demographic and clinical variables. In depression, panic attacks are associated with increased odds of suicide attempt even after controlling for demographic and clinical variables. Furthermore, panic attacks can differentiate those who attempt suicide from those with ideation only.

The potential medical applications of microarrays have generated much interest, within the biomedical community. Numerous potential sources of variation have raised concerns regarding assay consistency and data quality. Previous studies have highlighted RNA integrity as having a major effect on data quality. We describe here a comparison of the performance characteristics of the Agilent (Bioanalyser) and Lab901 (Screen Tape System) platforms, and their capacity to determine sample RNA integrity.
