Information on population-specific genomic variants provides important insights to link between genotypes and phenotypes. To facilitate genomic medicine research, this study aims to detect and characterize sequence variations enriched in the coding regions of the genome in the Chinese population residing in Taiwan. DNAs from 11 unrelated Taiwanese individuals were enriched for coding regions (i.e., exome) and followed by deep sequencing. Approximately 30 Gb of high-quality data from massively parallel sequencing was obtained. On average, ∼60% of the total reads were uniquely mapped to the human reference genome and overall 97% of the target regions were covered by sequence reads, resulting in an average enrichment fold relative to target size of ∼50-fold. Comprehensive variant detection and analysis were performed with various in-house established bioinformatics pipelines, and information for different types of variations including single nucleotide variants, short insertions and deletions, and copy number variations was collected. The sequence variations were crossed with variants in the public databases to identify ethnic-specific variants. To study the impact of sequence variations that are enriched in the Taiwanese Han population, variants that are present in at least two exomes (i.e., minor allele frequency &gt;9%) were further annotated. Overall, we detected 308 loss-of-function variants that belong to 291 genes in the Taiwanese Han Exome Sequencing dataset. Functional annotation revealed a significant pathological influence of these loss-of-function-associated genes in the risk of various human diseases including lung cancer. This is the first NGS (next-generation sequencing)-generating dataset to comprehensively report coding sequence variants in the Taiwanese Han population. Given that the Taiwanese Han population is the Han Chinese residing in Taiwan, it is normally underrepresented in population-genetics studies. We believe the study will contribute valuable information that will have an impact on medical as well as population genetics.</p></div>","PeriodicalId":100178,"journal":{"name":"Biomarkers and Genomic Medicine","volume":"6 4","pages":"Pages 133-143"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.bgm.2014.05.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76228625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiation combined with chemotherapy (also known as concurrent chemoradiotherapy or CCRT) is often used prior to surgery for treating severe cases of colorectal cancer. However, responses of individual tumors to CCRT differ. Therefore, in light of the variability in radiation sensitivity among different tumors, identifying the factors that can be applied to predict CCRT efficacy prior to treatment will aid in making decisions regarding an appropriate treatment strategy. In the present study, we used a gene chip to analyze the expression of candidate genes in the tumor cells of colorectal cancer patients prior to and after treatment with CCRT, in order to identify molecular markers that can predict the efficacy of CCRT. First, we selected a total of 15 CCRT candidate genes based on the results of previous studies, which used the microarray method to select CCRT response-related genes that were also related to tumor malignancy. We collected preoperative CCRT tumor tissues from 17 colorectal cancer patients for whom the efficacy of CCRT had already been determined and used gene chips to analyze the expression of CCRT-related genes in the tissues of these patients. We then compared the results for the expression of CCRT-related genes with those for the clinical efficacy of CCRT.

Second, we selected 11 candidate miRNAs related to colorectal cancer (CRC) from our previous studies and then designed the probes based on the sequence of the candidate miRNAs and constructed a miRNA biochip. miRNAs were extracted from CRC cell line SW620 and were detected by enzymatic biochip assay. According to the results, we found that this miRNA biochip can effectively detect the miRNAs by using a specific stem-loop RT primer to synthesize cDNA.
