RESUMO

KapWeb is an interactive tool for the determination of cancer survival rates based on case outcomes compiled from more than half a million records from cancer registries all over Japan, and we believe that both the tool and the call for data openness and transparency are important.

RESUMO

Prostate cancer is emerging as a significant global public health burden. The incidence and prevalence of prostate cancer has increased in Japan, as westernized lifestyles become more popular. Recent advances in genetic epidemiology, including genome-wide association studies (GWASs), have identified considerable numbers of human genetic factors associated with diseases. Several GWASs have reported significant loci associated with serum prostate-specific antigen (PSA) levels. One GWAS, which was based on classic GWAS microarray measurements, has been reported for Japanese so far. In the present study, we conducted a GWAS of serum PSA using 1000Genomes imputed GWAS data (n =1,216) from the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study, to detect candidate novel genetic loci that influence serum PSA levels in Japanese. The association of SNPs/genetic variants with serum PSA as a continuous variable was tested using the linear Wald test. SNP rs10000006 in SGMS2 (sphingomyelin synthase 2) on chromosome 4 had genome-wide significance (P <5×10-8), and eight variants on three chromosomes (chromosomes 12, 14, 15) had genome-wide suggestive levels of significance (P <1×10-6). With an independent data set from the J-MICC Shizuoka Study (n = 2,447), the association of the SGMS2 SNP with blood PSA levels was not replicated. Although our GWAS failed to detect novel loci associated with serum PSA levels in the Japanese cohort, it confirmed the significant effects of previously reported genetic loci on PSA levels in Japanese. Importantly, our results confirmed the significance of KLK3 SNPs also in Japanese, implying that consideration of individual genetic information in prostate cancer diagnosis may be possible in the future.

RESUMO

BACKGROUND: The Japan Multi-institutional Collaborative Cohort (J-MICC) study was launched in 2005 to examine gene-environment interactions in lifestyle-related diseases, including cancers, among the Japanese. This report describes the study design and baseline profile of the study participants. METHODS: The participants of the J-MICC Study were individuals aged 35 to 69 years enrolled from respondents to study announcements in specified regions, inhabitants attending health checkup examinations provided by local governments, visitors at health checkup centers, and first-visit patients at a cancer hospital in Japan. At the time of the baseline survey, from 2005 to 2014, we obtained comprehensive information regarding demographics, education, alcohol consumption, smoking, sleeping, exercise, food intake frequency, medication and supplement use, personal and family disease history, psychological stress, and female reproductive history, and collected peripheral blood samples. RESULTS: The baseline survey included 92,610 adults (mean age: 55.2 [9.4] years, 44.1% men) from 14 study regions in 12 prefectures. The participation rate was 33.5%, with participation ranging from 19.7% to 69.8% in different study regions. The largest number of participants was in the age groups of 65-69 years for men and 60-64 years for women. There were differences in body mass index, educational attainment, alcohol consumption, smoking, and sleep duration between men and women. CONCLUSIONS: The J-MICC Study collected lifestyle and clinical data and biospecimens from over 90,000 participants. This cohort is expected to be a valuable resource for the national and international scientific community in providing evidence to support longer healthy lives.

RESUMO

We report two Japanese women with androgen excess symptoms. Analyses of 21-hydroxylase gene demonstrated that a 24-year-old Japanese woman had a homozygous mutation of IVS2-13 A/C>G, while a 25-year-old Japanese woman had a compound heterozygous mutation of I172N and E245del1nt, a novel mutation which would result in completely nonfunctional enzyme due to a frame shift. As IVS2-13 A/C>G and I172N have been classified as mutations leading to severe impairment in enzyme activity, this study not only clarified a novel mutation causing 21-hydroxylase deficiency, but also demonstrated that genotype and phenotype do not correlate well in these cases.
