In Caenorhabditis elegans, the dosage compensation complex (DCC) specifically binds to and represses transcription from both X chromosomes in hermaphrodites. The DCC is composed of an X-specific condensin complex that interacts with several proteins. During embryogenesis, DCC starts localizing to the X chromosomes around the 40-cell stage, and is followed by X-enrichment of H4K20me1 between 100...

A report from the Digital Curation Centre (DCC) / Regional eScience Collaborative Workshop, held at the eScience Institute in Edinburgh on June 12, 2008. The DCC is committed to forging and strengthening links between the digital preservation and eScience communities via its eScience Liaison team. This event was the fifth in a series of workshops which are being arranged throughout the UK, with...

The seasonal structure of quarterly UK and Japanese consumption and income is examined by means of fractionally-based tests proposed by Robinson (1994). These series were analysed from an autoregressive unit root viewpoint by Hylleberg, Engle, Granger and Yoo (HEGY, 1990) and Hylleberg, Engle, Granger and Lee (HEGL, 1993). We find that seasonal fractional integration, with amplitudes possibly v...

Dosage compensation in male Drosophila relies on the X chromosome-specific recruitment of a chromatin-modifying machinery, the dosage compensation complex (DCC). The principles that assure selective targeting of the DCC are unknown. According to a prevalent model, X chromosome targeting is initiated by recruitment of the DCC core components, MSL1 and MSL2, to a limited number of so-called "high...

Myosin X (Myo X), also known as MYO10, is an unconventional actin-based motor protein that plays an important role in filopodium formation. Its intra-filopodia movement, an event tightly associated with the function of Myo X, has been extensively studied. However, how the motor activity of Myo X and the direction of its movements are regulated remains largely unknown. In our previous study, we ...

Deleted in colorectal cancer (DCC) and neogenin are receptors of netrins, a family of guidance cues that promote axon outgrowth and guide growth cones in developing nervous system. The intracellular mechanisms of netrins, however, remain elusive. In this paper, we show that both DCC and neogenin become tyrosine phosphorylated in cortical neurons in response to netrin-1. Using a site-specific an...

The IEEE 802.11p is the technology dedicated to vehicular communications to support road safety, efficiency, and comfort applications. A large number of research activities have been carried out to study the characteristics of the IEEE 802.11p. The key weakness ...

The development of colon carcinomas is associated with allelic deletions on chromosomes 5q, 17p, and 18q. The DCC gene located on chromosome 18q21.3 codes for a potential tumor suppressor gene related to cellular adhesion receptors. We investigated the expression of this gene in several pancreatic carcinoma cell lines and in patients with ductal adenocarcinomas of the pancreas. In 8 of 11 cell ...

Extracellular netrin-1 and its receptor deleted in colorectal cancer (DCC) promote axon branching in developing cortical neurons. Netrin-dependent morphogenesis is preceded by multimerization of DCC, activation of FAK and Src family kinases, and increases in exocytic vesicle fusion, yet how these occurrences are linked is unknown. Here we demonstrate that tripartite motif protein 9 (TRIM9)-depe...

We have previously observed that the frequency of loss of heterozygosity (LOH) on chromosome 18q was low in adenomas and intramucosal carcinomas, whereas invasive carcinomas exhibited a high frequency in familial adenomatous polyposis patients (M. Miyaki et al., Cancer Res., 50: 7166-7173, 1990). In the present study, LOH at the DCC locus on chromosome 18q and the expression of DCC gene into mR...
