Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC)/target of methylation-induced silencing/PYCARD represents one of only two proteins encoded in the human genome that contains a caspase recruitment domain (CARD) together with a pyrin, AIM, ASC, and death domain-like (PAAD)/PYRIN/DAPIN domain. CARDs regulate caspase family(More)
UNLABELLED ArrayCyGHt is a web-based application tool for analysis and visualization of microarray-comparative genomic hybridization (array-CGH) data. Full process of array-CGH data analysis, from normalization of raw data to the final visualization of copy number gain or loss, can be straightforwardly achieved on this arrayCyGHt system without the use of(More)
Recently, the -160 C/A polymorphism, located within the regulatory region of Ecadherin promoter, has been shown to influence E-cadherin transcription by altering transcription factor binding. We examined the effect of this polymorphism on risk of gastric cancer and on histological classification of intestinal- and diffuse-type gastric cancer in 146 normal(More)
Cadherins (CDHs) are important in maintenance of cell adhesion and polarity, alterations of which contribute to tumorigenesis. Alterations of E-cadherin, a prototype CDH, have been reported in many cancers. However, alterations of unconventional CDHs, including CDH10, CDH24 and DCHS2 are largely unknown in cancers. Aim of this study was to explore whether(More)
Metabolic reprogramming is an emerging topic in cancer research. However, genetic alterations in genes encoding enzymes involved in amino acid metabolism are largely unknown. The aim of this study was to explore whether genes known to be involved in amino acid metabolism are mutated in gastric cancer (GC) and/or colorectal cancer (CRC). Through a public(More)
Mucins are important in tumorigenesis and expressional alterations of mucins are common in human cancers. A membrane-bound mucin MUC15 and secreted mucins MUC4 and MUC7 are known to involve in tumorigenesis, but their mutation status in cancers remains unknown. Aim of this study was to explore whether MUC4, MUC7 and MUC15 genes are mutated and(More)
Although the colorectal adenoma-to-carcinoma sequence represents a classical cancer progression model, the evolution of the mutational landscape underlying this model is not fully understood. In this study, we analyzed eight synchronous pairs of colorectal high-grade adenomas and carcinomas, four microsatellite-unstable (MSU) and four-stable (MSS) pairs,(More)
Although ductal carcinoma in situ (DCIS) precedes invasive ductal carcinoma (IDC), the related genomic alterations remain unknown. To identify the genomic landscape of DCIS and better understand the mechanisms behind progression to IDC, we performed whole-exome sequencing and copy number profiling for six cases of pure DCIS and five pairs of synchronous(More)
The SM1311 family is an Ashkenazi family with dominantly inherited predisposition to colorectal adenomas and carcinomas and has a high-penetrance locus in chromosome 15q, with a multipoint logarithm of the odds score of 3.06 at marker D15S118. In the present study, we performed a high-density loss of heterozygosity study with 13 polymorphic microsat-ellite(More)
Although recurrent gene fusions such as JAZF1-JJAZ1 are considered driver events for endometrial stromal sarcoma (ESS) development, other genomic alterations remain largely unknown. In this study, we performed whole-exome sequencing, transcriptome sequencing and copy number profiling for five ESSs (three low-grade ESS (LG-ESS) and two undifferentiated(More)
