Every living organism in its environment represents a biochemically unique system whose biological functions can be better understood through analytical measurements. Isolated analytical measurements, which may help assessing the state of health within the organisms under study, are now routinely being made. Distinguishing between the “apparently healthy” and “diseased” individuals in clinical chemistry assays is often complicated by the biochemical individuality which has been recognized as an experimental complication of acquiring data from human subjects. Moreover, this aspect commonly results in considerable ranges for both often exist. The rapidly developing fields of genomics, transcriptomics, proteomics, glycomics, and metabolomics are generating a vast body of biochemical information which is only sorted out through Systems Biology. Systems Biology, here, is referring to the strategy of pursuing integration of complex data about the interactions in biological systems from diverse bioanalytical techniques using multidisciplinary tools and personnel. Many research laboratories have been focusing their efforts on the overwhelming task of characterizing proteins and their voluminous posttranslation modifications following the Human Genome Project and the subsequent efforts to characterize the genomes of model animals. Inquiries into the glycomes and metabolomes of physiological fluids and tissues have been prompted by the unprecedented advances in biomolecular characterization and quantification of proteins. The abality to address these inquiries have been mainly attributed to the methodological/technological advances in biomolecular mass spectrometry and microscale separation science, as well as to the greatly improved computational capabilities (bioinformatics) which is facilitating fast data visualization and interpretation. The overarching activities in my research group are focused on the utility of molecular mass spectrometry to understand biomolecular changes attributing to disease development and progression. Glycomics and glycoproteomics continue to be highly dynamic and interesting research areas due to the needs to comprehensively understand the biological attributes of glycosylation in many important biological functions such as immune response, cell development, cellular differentiation/adhesion and host-pathogen interactions. Moreover, aberrant glycosylation for decades has been recognized as the attribute of many mammalian diseases, including osteoarthritis, cystic fibrosis and cancer. This being said, glycomic and glycoproteomic analyses remain to be analytically very challenging mainly due to the high complexity and microheterogeneity of glycosylation processes and machineries. Therefore, more cutting-edge-analytical approaches are needed to allow more comprehensive characterization of glycosylation and subsequently better understanding of its biological roles. The ultimate goal of the research activities of my group is the comprehensive characterization of glycoprotein glycosylation sites and microheterogeneity of such sites. Accordingly, we are developing several glycomic and glycoproteomic approaches facilitating the achievement of this ultimate goal. Since interpretation and processing of glycomic and glycoproteomic data is laborious and time consuming, we are also collaborating with bioinformatics experts to develop different bioinformatic tools aiding rapid and automated data interpretation and processing. These research activities are intended to facilitate the analysis of large numbers of biological samples, thus facilitating a better understanding of disease development and progression at a molecular level.,Dr.YehiaMechrefProf.美国德克萨斯理工大学 DepartmentChairman,Professor,andDirectoroftheTTUCenterforBiotechnology&Genomics Education:Ph.D.,OklahomaStateUniversity PostdoctoralStudy,IndianaUniversity ResearchArea:... 邀请授课：联系客服微信：17052226000（仅限嘉宾演讲类咨询，其他勿扰） 免责声明：以上内容（包括文字、图片、视频）为您提供嘉宾信息展示，本平台信息仅交流。若您发现嘉宾信息需要更新或移除或版权，请联系我们告知并提供证明，我们将删除或更新！
