- [This is a posting of a notice about the BIO-MATRIX project, its aims,
- and current activities. It appears irregularly.]
-
- BIO-MATRIX is not a database or a functional tool. The concept's
- underpinnings are best described in the "Final Report of the Workshop
- on Matrix Biology". I will summarize here my interpretation of
- the Matrix concept.
-
- The Matrix of Biological Knowledge is a response to the way biologists
- reason about their systems. Physicists have recourse to first
- principles and in the last 20 years we've seen implications of quantum
- mechanics on the cosmological scale. The complexity of biological
- systems is such that it's going to be a *long* time before one can
- reason a Tetrahymena from first principles. As each scientist thinks
- about their particular system, they consciously (and frequently
- unconsiously) reason about their system by analogy. A striking
- example of this appeared on the cover of Science; the
- three-dimensional structure of _ras_ is essentially identical to one
- proposed a few years before, based on what was known about a property
- of _ras_, that it binds GTP. By examining an already-determined
- tertiary structure of a GTP-binding protein, they were able to make an
- accurate prediction of what _ras_ would look like.
-
- The Matrix concept wants to organize biological knowledge so
- that the predictive power of models in different disciplines can be
- applied to a different, perhaps new, discipline. Molecular biologists
- have been using such reasoning for years; but what does the hydra
- biologist know of the models in toxicology? Are there any
- toxicological model systems that speak to a protist system? I don't
- know the answer, and I doubt that anyone else does either.
-
- The Matrix subsitutes reasoning by analogy for reasoning
- from first principles. The proposal is to combine biological
- knowledge in three ways; (1) collect data into databases, and have the
- agencies that fund research get serious about the proper disposition
- of the knowledge they've been funding (such as requiring, as a
- condition of grant funding, any resulting data to be submitted to
- GenBank for nucleotide information; PIR for protein information; and
- Brookhaven for x-ray crystallographic information). (2) organize the
- databases in such a way that access to them is transparent. You tell
- your Macintosh that you want to know all about X; the program
- goes and calls MedLine, ToxLine, BRS, and whatever else...including
- databases that you may not know exist... and retrieves the information
- for you. This is the knowledge base component of the Matrix (yes,
- highly simpilified). (3) Tools to help get that information even if
- you don't know it's there; this is the Information Retrieval component
- of the Matrix.
-
- Another view follows.

- The Gene-Server at the University of Houston is an archive server
- containing Matrix information. It can be contacted from most networks and
- can reply to all known networks (no failures yet!). For info, send
- the line
- help

- gene-server@bchs.uh.edu (internet),
- gene-server%bchs.uh.edu@CUNYVM (BITNET, EARN, NETNORTH)
-
- For Biomatrix-specific information, send the line
- send matrix help
- to the gene-server address.
