・Abstract: The understanding of the biological mechanisms underlying human diseases is one of the main challenges in biological sciences. Although several efforts, the large number of heterogeneous factors that influence the genesis of a disease makes it a very hard task. One of the challenges consists in understanding diseases by developing methods to statistically analyze and computationally manipulate big data. This difficulty is generated by ultra large data size, heterogeneity, multidimensionality, and presence of intrinsic noise. In this context, computationally intensive statistical methods developed by our group are presented with applications in neuroscience and molecular biology. In neuroscience, the focus is on the analysis of resting-state fMRI data of ~600 individuals diagnosed with ADHD and ~900 subjects with ASD. In the context of molecular biology, partial results obtained from the study of miRNA expression of a cohort of ~2,000 breast cancer subjects are presented.

・Abstract : Each human being has different combinations of genomes, which creates genomic variations. Thus, there are variations in phenotypes such as people’s appearances and constitutions. In order to understand how human biological variability was shaped and maintained, it is important to know 1) how humans spread all over the world and how they have adapted to their environment, 2) how large the variability generated as a result of chance. At present, in our laboratory, we put special focus on the people in the Ryukyu Chain to deepen our research on the features of genome and phenotypes in Asians and the background on how such features were formed. Furthermore, we are tackling to identify the genomic factors on visible traits such as complexion. The advancement of the recent genome analysis technology and dense catalog of genomic variations have dramatically transformed the strategy of biomedical studies, and it was required for researchers to face a large volume of data. In this seminar, we would like to introduce our study as well as to show the overview of the fast-evolving research methods of population genomics.

The 50th In Silico Megabank Research Seminar will be held on Friday, September 26.
This Time, we will be welcoming Dr. Kitano, Ibaraki University as our lecturer, and he will be speaking on “Evolution of Blood Group Genes”.

College of Engineering, Ibaraki University)

・Abstract :. Small variance in the structure of erythrocyte cell surface is categorized into groups based on the antigen-antibody reaction, and this is what we call blood groups. The antigens of ABO type blood groups are sugar chains. The base is the sugar chain of type O. The sugar chain comprised of the base with a terminal N-Acetylgalactosamine is type A and with a terminal galactose is type B. ABO type blood group genes are ones that code glycosyltransferase to link those terminal sugars. The difference in 2 amino acids above exon 7 creates the difference in the sugar attached, which in turn forms the sugar chain of type A or type B. Also, the frame shift due to single base deletion above exon 6 causes inhibition of the production of functional glycosyltransfrase, and as a consequence neither terminal sugar is attached. This is the sugar chain of type O. On the other hand, RH blood group genes are the ones that code proteins for transporters with 12 transmembrane domains, and the different types of the amino acids placed outer-membrane of these proteins are categorized in this group.
In this lecture, molecular basis and evolution of ABO and RH blood group genes are introduced.

On August 8th 2014, we, Tohoku University’s Medical Megabank, published an allele frequency of more than 5% on known variants in order to advance the validation of our Genome Reference Panel Draft. Though variant information of more than 1% will be sold in the future, we aim to improve the verification and accuracy of our draft version. Therefore, we are proud to announce that we are accepting research proposals aimed at achieving an allele frequency of less than 1% within variants.

1.)     Joint Research related to single nucleotide polymorphism with in the
ToMMo Genome Reference Panel Draft.
2.)     Joint Research related to deleting, inserting, and copying within the
ToMMo Genome Reference Panel Draft.
3.)     Joint Research contrasting the ToMMo Genome Reference Panel Draft to
healthy people.
4.)     Joint Research involving a case-compare study on an SNP array used on
Japanese people.

The 49th In Silico Megabank Research Seminar will be held on Friday, September 12.

This Time, we will be welcoming Dr. Kohda, Saitama Medical University　as our lecturer, and he will be speaking on “Comprehensive Genomic Analysis on Mitochondrial Respiratory Chain Disorder”.
・Date/Time : September 12(Friday) 17:00‐18:30
・Venue : Small Conference Room 2(3rd Floor), Tohoku Medical Megabank Building
・Title : Comprehensive Genomic Analysis on Mitochondrial Respiratory Chain Disorder
・Lecturer : Masakazu Kohda（Research Center for Genomic Medicine, Saitama Medical University）

＊This lecture is transferable as a class in the medical research-related lecture course.

・Abstract : Mitochondrial respiratory chain disorder (MRCD) is one of the intractable diseases and is an inborn error of metabolism with frequent incidence of 6.2 in 100,000 infants. Abnormality of various protein involved in respiratory chain complex has been revealed as a cause of MRCD; until now approximately 150 causative genes have been found. However, some part of causative genes and the mechanism of the development still remain unknown. In the research, 6 mitochondria-related genes were successfully found as new causative genes through comprehensive genomic analysis on MRCE. Furthermore, multiple genes with unknown direct relationship with MRCD were identified as causative genes for the occurrence of phenotype in patients. Data obtained in this research can contribute to the development of the foundation of genomic analysis for MRCD; thus, high usability of the findings from the data on the understanding of genes, which have been yet remained unknown, is expected.
