Proteomics & Improving the resolution of electrophoresis in protein separation At present, electrophoresis is the choice method to analyze complex protein mixtures. However, still we cannot analyze total protein species in a cell, since the number should be above several thousands. Then, we are working on the improvement of two-dimensional gel electrophoresis and capillary electrophoresis, which exert the best resolution for protein/DNA analysis within electrophoretic techniques. In the field of two-dimensional gel electrophoresis (2-D PAGE), we developed a technique of micro 2-D PAGE in native conditions. This technique was applied for the analysis of human serum/plasma proteins and animal serum/plasma proteins. Also, we developed a technique of micro 2-D PAGE in denaturing conditions and applied this for the analysis of polypeptides in human leukemic cell HL-60. @In the field of capillary electrophoresis, we have established the conditions for high-resolution capillary electrophoresis of native proteins . These conditions have been successfully applied for the analysis of human plasma/serum proteins. Further, we also established capillary electrophoretic conditions for separating DNA sequencing fragments and for separating SDS-protein complexes .


Human protein 2D gels at Biobase

The Danish Centre for Human Genome Research's 2-D PAGE Databases at the University of Aarhus contain data on proteins identified on various reference maps. You can display protein names and information on specific protein spots by clicking on the image in which you are interested. Also, you can search by protein name, keywords, Mr and pI or organelle or cellular component. Protein files contain extensive links to other databases or Web sites. The databases are being constructed for the study of global cell regulation, skin biology and bladder cancer. Procedures are illustrated with still images and videos. Paginated list output. Clickable image of human fibroblast proteins run in immobilized pH gradients. (Modified after Bjellqvist, B., Basse, B., Olsen, E. and Celis, J. E. Electrophoresis, 15, 529-539, 1994. All gels in the gallery will be labeled with Mr and pI. January 14, 1997 Major software upgrade applying to all databases (show images in basic-acidic and acidic-basic orientation; search by Mr and pI; list all proteins; display Mr and pI grid).

Mitochondrial proteins (LMMB-NCIFCRF, USA). This database is dedicated to the nuclear genes specifying the enzymes, structural proteins, and other proteins, many still not identified, involved in mitochondrial biogenesis and function. MitoDat highlights predominantly human nuclear-encoded mitochondrial proteins, although we are including proteins from other animals in addition to those currently known only from yeast and other fungal mitochondria, as well as from plant mitochondria. The database consolidates information from various biological databases, eg., GenBank, SwissPro, Genome Data Base (GDB), Online Mendelian Inheritance in Man (OMIM), et al. Because the mitochondrion has a central role in cellular metabolism, it is involved in many human diseases. This database should help us in studying these diseases. It is also hyperlinked to the report of the committee on human mitochondrial DNA, maintained by the Wallace group at Emory It can be accessed here and also from the results when searching mitoDat for mitochondrially encoded genes. The Report of the committee on human mitochondrial DNA is currently the most comprehensive source of information on mitochondrial DNA mutations, other defects, and disorders in which the mitochondrial DNA deficiencies have been associated.

Embryonal Stem Cells (ES)

Immunobiology Department, University of Edinburgh, UK Molecular control of hematopoietic commitment, differentiation and self renewal. One approach is use transgenesis to perturb/redirect/enhance hematopoietic commitment. However, although studies using retroviral transgenesis of cell lines and isolated hematopoietic stem cells (HSC) have begun to shed light on the molecular control of differentiation of HSC into more committed progeny, the transformed nature of cell lines, and the difficulties of retroviral infection of slowly cycling stem cell populations have limited their usefulness. Commitment to the hematopoietic lineage could be studied by transgenesis and gene knock out in whole animals, but transgenesis that affects hematopoiesis often has pleiotropic effects, not the least of which is common embryo lethality. An alternate approach to the study of commitment and differentiation which would allow facile transgenesis, use primary tissue and allow reproducible and quantifiable commitment of mesoderm to the hematopoietic lineage is indicated. In vitro differentiation of embryonal stem (ES) cells satisfies these criteria.

UCSF 2DPAGE (A375 cell line)

Database at University of Southern California, San Francisco. This server presents information on proteins identified following isolation by two dimensional polyacrylamide gel electrophoresis (2D PAGE). The proteins have been rapidly identified through extensive use of the mass spectrometry based peptide sequencing power of the UCSF Mass Spectrometry Facility, directed by Professor Alma L. Burlingame in the Department of Pharmaceutical Chemistry at the University of California San Francisco (UCSF).

Collaboration with Dr. Lois B. Epstein's Tumor Immunolgy and Interferon Research Laboratory in the Cancer Research Institute and the Department of Pediatrics at UCSF has led to identification of proteins present in malignant human cell lines. Of particular interest are proteins which are either induced or suppressed by Interferon-gamma and/or Tumor Necrosis Factor as the identified proteins may mediate the anti-tumor or immunomodulatory functions of the two cytokines.
