ENCORE #94! – Computer Targeting Cancer Cells

From the first moment my wife discovered she had breast cancer, there was a deafening silence from the men I know. Even ones whose wives, mothers or girlfriends had breast cancer seemed to have received a gag order from some Central Cancer Command and did little more than mumble about the experience. Not one to shut up for any known reason, I started this blog…That was four years ago – as time passed, people searching for answers stumbled across my blog and checked out what I had to say. The following entry appeared in June of 2016…

Targeting breast cancer cells seems to be a major new thrust in the fight against breast cancer. I talked about it a couple of months ago here as well as some years ago: http://breastcancerreaper.blogspot.com/2012/09/breast-cancer-research-right-now-2.html and here: http://breastcancerreaper.blogspot.com/2016/04/breast-cancer-research-right-now.html

But how do you get from the IDEA of targeting cancer cells to trying drugs to do it? Apparently, you can do computer models.

Now don’t get me wrong, I am NOT a fan of computer models. The model is only as good as the person who inputs the raw data and the person who writes the program. Computer models are notorious for spitting out inaccurate predictions and drawing false conclusions – not the machine’s fault, of course. Like I said, programmers and data entry folks. Also, the assumptions of the researcher can find their way into the model as well; but that’s happened since forever, so it’s not a new factor.

Here we have the following: “Researchers have built a model to investigate the metastasis of cancer by examining the metabolism of breast epithelial cells and look at the role of signaling. This research may contribute to the development of cell specific anti-cancer interventions.”

In English, then: researchers are looking at how the cells that typically erupt into breast cancer cells use the nutrients they get from the body and the waste materials they give off. With that kind of a trail, scientists can design drugs to follow the trail and destroy the cancer cells.

Sounds simple enough – sort of like the old story of Hansel and Gretel: going out into the forest, the smart little girl leaves an easily followed trail that her and her brother can follow back home.

In this case, the cancer cell leaves a trail that well-designed cancer drugs can follow. Then they can destroy the cancer cell. The way it’s done now, is that drugs like Taxotere (which interferes with cell division), Adriamycin (which inserts itself into the cancer cell’s DNA so the cells can’t make new cancer cells), and Cytoxan (which sneaks in as a harmless drug, then is converted by the cancer cell into a toxin) – but they aren’t perfectly targeted. They kill hair cells and T-cells that protect the body from infections.

The researchers, programmers, and data entry people are working to reduce the amount of damage current cancer drugs do while still maintaining the attack on cells.

So, while I won’t CHEER this new model on, I will certainly watch to see what kinds of effective results it produces!
