We present PEACE, a stand-alone tool for high-throughput ab initio clustering of transcript fragment sequences produced by Next Generation or Sanger Sequencing technologies. It is freely available from www.peace-tools.org. Installed and managed through a downloadable user-friendly graphical user interface (GUI), PEACE can process large data sets of transcript fragments of length 50 bases or gre...

We have previously determined that cytochrome P450-based oxidation is involved in resistance to the insecticides methyl parathion and carbaryl in geographically distinct Nebraska western corn rootworm populations. Three new family 4 cytochrome P450 (CYP4) gene fragments (CYP4AJ1, CYP4G18 and CYP4AK1) were cloned and sequenced from insecticide-resistant and -susceptible western corn rootworms. I...

We have obtained a novel c-kit complementary DNA (cDNA) from a colon carcinoma cell line, Colo201, and characterized its structure. The size of the transcript in Colo201 was approximately 3.5 kilobases and it hybridized to the c-kit cDNA fragments encompassing the kinase domain, but not to the cDNA fragments encoding extracellular and transmembrane domains. The predicted protein encoded by thos...

The present study was conducted to find the effect of three heavy metals, Ag, Hg and Pb on the expression level of a gene encoding plasma membrane H+-ATPase in Aeluropus littoralis. The experiment was laid out in a completely random design with three replications. The expression of the main gene was normalized to the expression of the housekeeping gene actin. Two 259 and 187 bp fragments were a...

Recent evidence suggests that proteolysis plays an important role in some forms of inherited and acquired von Willebrand disease (vWD). Because calpains and one or more enzymes released from polymorphonuclear leukocytes are known to proteolyze von Willebrand factor (vWF) in vitro with resultant loss of large multimers similar to that seen in IIA vWD, they have been suggested as being responsibl...

The presence of unpaired copies of a gene during meiosis triggers silencing of all copies of the gene in the diploid ascus cell of Neurospora. This phenomenon is called meiotic silencing and on the basis of genetic studies appears to be a post-transcriptional gene silencing (PTGS) mechanism. Previously, meiotic silencing was defined to be induced by the presence of a DNA region lacking an ident...
