PNNL: Atomic science to the rescue

Bergen, Norway
For some reason, Linda was not to excited by trolls

Have you ever heard of the Pacific Northwest National Laboratory?  Well, neither had I, until today.  I had heard vague rumors alleging that there was some sort of off-beat research outfit located in the Tri Cities area of central Washington (where all the atomic stuff went on) but –despite having a graduate student working there – I didn’t really know what they did.  As it turns out, we all should be interested in the PNNL: initiated in 1965, it currently employs 4,400 staff and has an annual budget of nearly $1 billion.  It is “the largest single supporter of basic research in the physical sciences in the United States”.  Too bad it’s in Richland.

Turns out the PNNL supports work in cancer biology as well, as this interesting article will attest:


To enjoy this article you will have to remind yourself of several things:

1)      In ovarian cancer there seem to be multiple genetic mutations.  In general, the study of such genes might be referred to as cancer genomics.
2)      Genes “code for” proteins.  Proteins do most of the important work within a cell.
3)      Not every gene in a particular cell is “expressed” (converted into a protein).  Some are expressed massively, some sparely – and most, not at all.  The study of active proteins is known as proteomics.  And so we have, inevitably, ovarian cancer proteomics.
4)      It follows, it seems to me, that it makes sense to study the proteins that are doing the dirty work, and perhaps pay less attention to their associated genes.

Well, the PNNL bio-folks have been studying the active proteins in examples of high-grade serous ovarian cancer (what Linda had.)  They found that they could distinguish between two groups, based on their proteomes.  Members of one group had a much better prognosis than members of the other: 75% 5-year survival rate vs 25%.  Presumably this knowledge eventually may inform individualized therapies.  Anyway, I hope so.

In case you find the web address given above a little opaque, try this:


As an aside: we owe an awful lot to our neighbors across the Pacific.  Japan, we all agree, gives us the  bulk of our better cars.  China, it seems, supplies us with a preposterous fraction of our cancer scientists.  Take the PNNL article, for instance:  it purports to have 47 authors - 23 with unmistakable Chinese surnames.
