The overwhelming number of genetic alterations identified through cancer genome sequencing requires complementary approaches to interpret their significance and interactions. Here we developed a novel whole-body insertional mutagenesis screen in mice, which was designed for the discovery of Pten-cooperating tumor suppressors. Toward this aim, we coupled mobilization of a single-copy inactivating Sleeping Beauty transposon to Pten disruption within the same genome. The analysis of 278 transposition-induced prostate, breast and skin tumors detected tissue-specific and shared data sets of known and candidate genes involved in cancer...

Understanding the drivers and limits of species radiations is a crucial goal of evolutionary genetics and molecular ecology, yet research on this topic has been hampered by the notorious difficulty of connecting micro- and macro-evolutionary approaches to studying the drivers of diversification. To chart the current research gaps, opportunities, and challenges of molecular ecology approaches to studying radiations, we examine the literature in the journal Molecular Ecology and re-visit recent high-profile examples of evolutionary genomic research on radiations...

The analytical method for ultra-trace metal impurities at μg kg(-1) level in high-purity Cd was examined by inductively coupled plasma mass spectrometry (ICP-MS) combined with matrix separation by Bio-Rad AG MP-1M anion exchange resin. After the separation of Cd, the metal impurities such as Li, In, Cr, Mn, Fe, Co, Ni, Cu, Ga, Sr, Ba and Pb were measured by an ICP-quadrupole mass spectrometer (ICP-QMS) and ICP-sector field mass spectrometer (ICP-SFMS). From the comparison of measured results, it was evaluated that the analytical sensitivity by ICP-SFMS was 10 times higher than ICP-QMS...

Early diagnosis of fascioliasis is critical in prevention of injury to the liver and bile ducts. Saposin-like protein (FhSAP-2) is probably the most ideal antigen of Fasciola hepatica for development of ELISA kits. SAP-2 has a conserved tertiary structure containing three disulfide bonds and conformational epitopes. Therefore, antigenicity of SAP-2 is greatly depends on disulfide bond formation and proper folding. We produced the recombinant truncated SAP-2 (rtSAP-2) in the SHuffle® T7 and Rosetta strain of E...

Saffron (SAF), the dried stigmas of Crocus sativus is commonly used for flavouring and coloring food. Studies on bioactivity of SAF have demonstrated its in vivo antioxidant activity. The aim of our study was to assess the impact of SAF intake on γ-radiation (RAD) induced: (a) chromosomal damage, (b) oxidative stress in liver and brain and (c) histopathological effects in the intestinal cells and male germ cells in mice. Freeze-dried aqueous extract of SAF was used for the experiments. Our preliminary cell-free DNA nicking assay using pBR322 DNA revealed protective effects of freeze-dried SAF extract against hydroxyl radical induced DNA damage...
