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...

The dosage compensation complex (DCC) of Drosophila melanogaster is capable of distinguishing the single male X from the other chromosomes in the nucleus. It selectively interacts in a discontinuous pattern with much of the X chromosome. How the DCC identifies and binds the X, including binding to the many genes that require dosage compensation, is currently unknown. To identify bound genes and...

AIMS Although frequent reduction or loss of DCC (deleted in colorectal carcinomas) has been demonstrated in gliomas, the association with cell kinetics and survival is still unclear. METHODS A total of 119 astrocytomas, comprising 39 grade IV, 36 grade III, and 44 low grade tumours, were immunohistochemically investigated, along with 26 normal adult brain samples and two fetal brains. The res...

BACKGROUND Deleted in colorectal carcinoma (DCC), one of the Netrin-1 receptors, belongs to the functional dependence receptor family, members of which share the ability to induce apoptosis in the absence of their ligands. Recently, we examined the methylation status of the DCC gene in colorectal carcinomas and found that aberrant methylation of the DCC gene was detected in 28 out of the 50 (56...

We argue that disoriented chiral condensate (DCC) domains are not well defined for temperatures above the Ginzburg temperature TG (≃ 0.7Tc). Above TG, the dynamics of DCC domains is dominated by thermal fluctuations leading to fluctuating orientation of the chiral field in a given domain. It implies that DCC domains may form even in relatively lower energy collisions where the temperature only ...

In many organisms, it remains unclear how X chromosomes are specified for dosage compensation, since DNA sequence motifs shown to be important for dosage compensation complex (DCC) recruitment are themselves not X-specific. Here, we addressed this problem in C. elegans. We found that the DCC recruiter, SDC-2, is required to maintain open chromatin at a small number of primary DCC recruitment si...

BACKGROUND Biventricular direct cardiac compression (DCC) can potentially support the failing heart without the complications associated with a blood/device interface. The effect of uniform DCC on left and right ventricular performance was evaluated in 7 isolated canine heart preparations. METHODS AND RESULTS A computer-controlled afterload system either constrained the isolated heart to cont...

AIM OF THE STUDY To assess quality of life (QoL) in cancer patients treated at home, at an in-patient palliative care unit (PCU), and at a day care center (DCC). PATIENTS AND METHODS QoL was assessed in advanced cancer patients at baseline and after 7 days of symptomatic treatment using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15-Pallia...

We consider the quantum state describing the Disoriented Chiral Condensate (DCC), which may be produced in high energy collisions. We show how a mean eld treatment of the quantum equations corresponding to the classical linear sigma model leads to a squeezed state description of the pions emerging from the DCC. We examine various squeezed and coherent state descriptions of those pions with part...
