Acyl carrier protein (ACP) is a small acidic protein and its primary structure is highly conserved in various bacterial sources. Despite its small size, it interacts with diverse proteins associated with many biosynthetic pathways. The three-dimensional structure of H. pylori ACP and its structural characteristics were clarified using NMR and CD spectroscopy. H. pylori ACP consists of four heli...

The t(10;11)(p13;q14) translocation results in the fusion of the CALM (clathrin assembly lymphoid myeloid leukemia protein) and AF10 genes. This translocation is observed in acute myeloblastic leukemia (AML M6), acute lymphoblastic leukemia (ALL) and malignant lymphoma. Using a yeast two-hybrid screen, the four and a half LIM domain protein 2 (FHL2) was identified as a CALM interacting protein....

Chromosomal deletion is frequent at the region between BRCA2 and RB1 in the q14 band of chromosome 13 (13q14) in human cancers, including prostate cancer, suggesting the presence of a tumor suppressor gene. However, no reasonable candidate has been identified thus far. In this study, we did genetic and functional analyses to identify and evaluate the 13q14 tumor suppressor gene. Hemizygous and ...

A female infant with multiple malformations and mental retardation was noted to have a rare de novo chromosome abnormality involving mosaicism with two cell lines, one with a ring chromosome 13, and the other with partial trisomy 13 owing to a complex rearrangement. Cytogenetic examination excluded the presence of a t(13q;13q) cell line and showed a cell line with a marker chromosome containing...

Q1: Au: Please confirm this is the correct author for correspondence Q2: Au: Edit OK? Or is text missing? “comprise” is not correct here—there needs to be more than one item or idea, i.e., the concept database comprises the concept-entity database and something else. Q3: Au: Edit for 2nd author name correct? Q4: Au: Is this the correct number of subcomponents? Q5: Au: Is 50% correct here? In al...

BACKGROUND VEGF driven angiogenesis plays a key role in cancer progression. We determined the clinical efficacy of bevacizumab monotherapy in patients with metastatic melanoma. METHODS AND FINDINGS Thirty-five patients with metastatic melanoma in progression were enrolled in this phase II, single arm clinical trial. Each patient received bevacizumab monotherapy 10 mg/kg q14 d until intolerabl...

We applied a combination of molecular cytogenetic methods, including comparative genomic hybridization (CGH), spectral karyotyping (SKY), and fluorescence in situ hybridization, to characterize the genetic aberrations in a panel of 11 cell lines derived from head and neck squamous cell carcinoma and 1 cell line derived from premalignant oral epithelium. CGH identified recurrent chromosomal loss...

Characteristic recurrent copy number aberrations (CNAs) play a key role in multiple myeloma (MM) pathogenesis and have important prognostic significance for MM patients. Array-based comparative genomic hybridization (aCGH) provides a powerful tool for genome-wide classification of CNAs and thus should be implemented into MM routine diagnostics. We demonstrate the possibility of effective utiliz...

The q13 to q15 region of human chromosome 12 is frequently and consistently rearranged in malignant and benign adipose tissue tumors as well as benign tumors of smooth muscle and salivary glands. A reciprocal translocation, (12;16) (q13;p11), is characteristic of the myxoid subtype of liposarcoma, whereas translocations within 12q13-14 are frequently observed in benign lipomas. We are using pul...

The expression of eight serologically and biochemically distinct human cell surface antigens defined by monoclonal antibodies was examined on a panel of rodent-human somatic cell hybrids. Cosegregation was observed for human chromosome 11, and surface expression of all eight antigens was studied. Serological analysis of hybrids containing defined segments of human chromosome 11 permitted the re...
