SAY THAT AGAIN., please. SLOWLY.


An Alaskan femme fatale

WANTED:  Science writer.  Must have a Ph.D. in molecular genetics, articles published in the NYTimes, New Yorker magazine, and Playboy – and a burning desire to live in Philadelphia.  If you qualify, contact the Wistar Institute at once, and volunteer to write their press releases. 

No, don’t.  This is a joke. 

I was goaded to write this bit of nonsense by at least an hour of struggle with the press release noted below.  Press releases, I would have thought, are finely crafted attempts to explain something important to the public, generate excitement – and indirectly perhaps secure more revenue.  Well, whatever “public” this thing is aimed at certainly doesn’t include me.

So, all I can figure out is that the white coats at Wistar have shown that a particular epigenetic protein acts as an important tumor-suppressor, and when mutated raises holy hell.  What to do about it seems to remains questionable..  I could tell you more, but I probably would get it wrong,  and you would forget it anyway.  So, if you are really curious, click on the link below.

Geez!  Why didn’t they just email the half dozen people in the world that would find this thing comprehensible?


Note that I am not implying that this work isn’t important.  Almost certainly, it is.  It’s just that an hour of knocking my head against a literary stone wall has made me a little grumpy.

ACT, TIL, interleukin-2 - AND ALL THAT FASCINATING STUFF


Linda and her lifelong friend Pat

If you don’t know what BRCA1 and BRCA2 are by now you haven’t been paying attention.  The BRCA part is short for breast cancer.  BRCA1 and 2 are genes that, when mutated, greatly increase a woman’s chance of getting breast cancer.  As it happens, the same mutations increase susceptibility to ovarian cancer as well.  But you knew all that.

The OVCA tie-in led me to the article cited below (bottom).  It describes the work of Steven Rosenberg and his lab, at the NCI.  Rosenberg obviously is an august personage in the cancer world; a book I reviewed recently


quotes an anonymous source, saying “you don’t criticize Steve publically”.  But, whatever, he is famous, hyperactive, brilliant, successful, and intense.  The world needs more Steve's

The article under discussion concerns an immunotherapy technique that has produced some wonderful results.  It is known as ACT (adaptive cell transfer).  Simplistically, ACT consist of extracting TILs (tumor-infiltrating leucocytes) from the patient’s tumor, then with the help of a drug called IL-2 (Interleukin-2) making zillions of copies, later injecting them back into the patient.  TILs consist of immune cells, T and B, that recognize the malevolence of the tumor and attempt to kill it.  Presumably they fail because they are somehow out-gunned.  The purpose of ACT seems to be to provide massive reinforcements to the good guys.

(Always make allowance for my pre-school level of sophistication in these matters.)

BTW, you may wonder just what is meant by Interleukin-2.  Well, here is its description, taken from the glossary of the book cited above:

“A cytokine released by T helper cells that is necessary for T-cell activation, proliferation, and maturation”.  See the kind of stuff I put up with, just to help you understand cancer?

A cytokine, by the way, is a family of “signaling molecules…involved in immune cell signaling”
There.  Did that help?

Okay, Sidd: Now get back to work. Please.


Linda and cousin Elsie, on a good Borrego flower year

Remember Siddhartha Mukherjee?  Of course you do; I have written about him many times, and you read all my stuff, of course.  Well, Dr.  Mukherjee is on the Columbia University faculty.   His research area is cancer; his hobby appears to be creative writing.  He has written several highly acclaimed books:  The Emperor of All Maladies, which I rated A+ #1 you-gotta-read-it


as well as the distinctly inferior but still worthwhile The Gene, an intimate history. 


I gave Sidd’s second book a solid B for content an A for style - but an A+ as a sleep aide.

Mukherjee also has written a quite a few magazine essays, most  of which are useful.  One of my favorites deals with  epigenetics:


Well, my research team of Joanne and Dick Ingwall has alerted me to yet another Mukherjee effort, published by the NYTimes.  The title is The Search for Cancer Treatment Beyond Mutant-Hunting. 
Here it is:


I can’t seem to extract much that is useful from this essay.  It seems to be telling us that there is more to targeted cancer therapy than simply matching the disease to the relevant set of mutations, then applying the appropriate drug.  Well, Gee, who would have thought of that?  I guess in the last page or so Mukherjee is hinting at what we should be doing, but after several attempts I have still to recognize anything resembling a concrete plan.  Maybe I’m just too stupid, but I don’t think so.  I think that Dr. Siddhartha Mukherjee simply likes to write.

God damn it Sidd, get back into the lab and cure cancer!  Afterwards, you can write the Great American Literary Masterpiece.

IMMUNOTHERAPY FOR THE MASSES


FINNEGAN: Junior partner in famous Weise Brothers Marine Biology lab

Well, bloody hell!  I have run on a U Tube video, a whopping 3.5 minutes in length, that gives you a painless elementary school rendition of something you already should know: how immunotherapy works.  Abbreviated and non-technical as it is, nevertheless it is worth viewing.  Trouble is, I can’t persuade my computer to let me give you an address that will actually work.  So – Google “Immunotherapy: how the immune system fights cancer”.    It is an NCI video.  Also, if you fool around with the NCI web site you can learn lots more about immunotherapy.  Do it.

HOW (with a little luck) TO AVOID CANCER


Linda and Murphy
He could be a nasty big brute, but he loved Linda.
Who wouldn't?

You already know this stuff, but it won’t hurt to watch this short video.


Well, hell, I can’t get the video to play.  Maybe you will have better luck.

WHY WE ARE SMARTER THAN MONKEYS, AND THE PRICE WE PAY


One of my favorite pictures

Lord, this genetics stuff is interesting!  As I have said several times, if I had it to do over I would spend my life doing cancer-related biomedical research.  As part of that profession I would also become a whiz-bang computer jock – and, with those talents I would naturally start my own biotech business and become as rich as Bill Gates!  Oh, well – Bill never got to camp out in a windstorm in Patagonia – and get paid for it.

That piece of nonsense is meant to introduce an article by Dr. Francis Collins, whom I have discussed before.  Dr. Collins is Director of the National Institutes of Health (NIH) and former director of the “official” program to sequence the human genome.  Apparently he keeps his hands wet doing things in the laboratory, as well as running a multi-billion dollar federal agency – and still has time to post fascinating blogs on stuff NIH is doing.

 The particular blog referenced below concerns the genetic reason we humans are smarter than monkeys. Briefly, it has to do with the duplication, in humans, of a gene called NOTCH2 , which we share with other primates.  We carry multiple copies – which makes us smart.  However, it also makes us susceptible to an array of nasty imperfections, ranging from ADHD syndrome to microcephaly.

 It appears that here is no such thing as a perfectly white shirt; they all have a tiny stain somewhere.

So monkeys may not be as smart as we are, but maybe they are happier.  You think?

So, anyway, Francis Collins is a remarkable human being.  He is an accomplished, highly respected scientist – and  a practicing Christian.  He has written a book, The Language of God: A scientist presents evidence for belief, which I am reading.  (You can get it through Abebooks for $3.57, with free shipping.)  I have spent my entire life trying not to think about God; I knew I should, but it seemed too hard and I was too busy.  Now, however, I am 85, and not busy.  Maybe it is time.

EGGS AND CANCER


Biodegradable silica?

Ever wonder where cancer researchers get samples to experiment on?  Well, me neither, but maybe I should have.  It appears that they grow them on mice, but that takes time (like, weeks), and mice cost significant money (like, dozens of bucks per).  Now some smart people in Japan, France, and Saudi Arabia (!) have shown that ovarian tumors can be grown on embryonic chickens (e.g., eggs) quickly, and at a fraction the cost. Furthermore, they have experimented with killing the tumors using “biodegradable silica nanoparticles”.  This seems to work, but leaves me scratching my head: how in heck can something made of silica (think, sand) be biodegradable?

Maybe Saudi Arabia is the source of the sand.

BOOK REVIEW: A Cure Within


Linda and Laura Hansen

It is a dreary day here in Bellingham; the first genuinely rainy day in over a month.  I should seize the occasion to get this over with.

“This” is a review of a new cancer book, A Cure Within: Scientists unleashing the immune system to kill cancer.  The author is Neil Canavan, who is described as “a freelance journalist specializing in science and medicine”.  He is currently “scientific adviser” to something called the Trout Group, which describes itself as “ the leading global investor relations and strategic advisory firm servicing the life sciences industry  Whatever: Neil has an M.S. degree in molecular biology, which means he knows a lot more about this stuff than I do, so I had better tread lightly.  However…..

I am approaching the end of Neil’s book, for the second time.  At first reading, I hated it.  In fact, I hated it so much that I undertook a second reading expressly to select evidence to damn it to perdition.  Then a funny thing happened; on a second go I began, grudgingly, to like it!  No way I tackle it a third time; I might find myself applying for membership in Neil’s fan club!

So, what’s good and what’s bad?  Well – I hate the guy’s style, for one thing.  He is capable of telling us that “Viruses are really, really small” at one point, then toss a phrase like “… validated target proteins with glial cell-derived neutrotrophic factor or tyrosine hydroxylase”… at you a few pages later.  Also, to make his book a bit more user friendly, I suppose, he broke it up into bite-sized sections, each with its own little title.  One such is, I kid you not – “Bite Me”.  Another is “Blessed are the Cheeseheads”.  Most are serious and even useful, but a few definitely are not..

Maybe the problem is that I read the wrong book.  The book I was looking for would have explained immunotherapy in a straightforward manner that even someone without an M.S. in molecular biology could assimilate; What Neil did – to enhance reader appeal? – was to tell the story through mini-biographies of selected scientists involved in the evolution of IO (immuno-oncology), twenty five in all. 
The life stories of some of these folks are interesting, but Neil struggles to make them even more so, to little effect..  For instance: he is capable of asking one august senior scientist  (which do you like better) the Beetles, the  Rolling Stones, or the Grateful Dead?  Now, if he’d asked Willie Nelson Johnny Cash, or Patsy Cline I might have forgiven him.

So, anyway, the saga of IO is traced in this book, but in a choppy, capriciously segmented way that I find disappointing.  There is some good stuff here, but you have to dig for it.  My advice: wait a few months, and then buy a like-new copy from Abe books, for $3.57, with free shipping.
