A Breakthrough?

A single anti-body that shrinks a wide variety of human tumors in mice.

They showed that nearly every human cancer cell they examined expressed CD47 — usually at higher levels (on average, about three times more) than did non-cancerous cells. Furthermore, people whose cancer cells express a lot of CD47 tend to have shorter life spans than people with similar cancers that express less CD47. This suggests that an analysis of the levels of CD47 expression in some types of tumors could be a valuable prognostic tool for patients and their doctors.

Willingham and Volkmer then implanted the different human tumor cells into matching locations in the bodies of mice — breast cancer tumors into the mammary fat pads, and ovarian cancer tumors into the abdomen, for example. Once the tumors were well-established (after two weeks or more), they treated the animals with the anti-CD47 antibody.

The researchers saw that most of the established tumors begin to shrink and even, in some cases, disappear within weeks of treatment with the antibody. In one case, antibody treatment cured five mice injected with the same human breast cancer cells. When the tumor was gone, the treatment was discontinued; the mice were monitored for four months with no signs of recurrence.

“These results indicate that anti-CD47 antibodies can dramatically inhibit the growth of human solid tumors by blocking the ability of CD47 to transmit the ‘don’t-eat-me’ signal to macrophages,” concluded the authors.

…is there no such thing?

I’m kind of amused by the commenter who fantasizes that he’s making some kind of point by claiming that “Eades is not a scientist.” What does he think a scientist is, or does?

Speaking of nutritional science, this is junk nutritional science:

“Overall, we found that obese rats fed a high-fat, low-carb diet — comparable to that humans would consume — had larger, more damaging and deadly heart attacks than rats fed the control diet,” Lloyd says. “Our findings also suggest that, at the cellular level, a high-fat, low-carb diet impaired recovery of heart function in obese rats immediately following a heart attack.”

Only one problem. You can’t extrapolate dietary results for rats to humans. We have a different physiology and natural diet. Actually, there’s a lot of junk science based on rat research.

Link was missing. Fixed now.


approaches its day of reckoning. As do its authors, in November.

Rarely has one law so exemplified the worst of the Leviathan state — grotesque cost, questionable constitutionality and arbitrary bureaucratic coerciveness. Little wonder the president barely mentioned it in his latest State of the Union address. He wants to be reelected. He’d rather talk about other things.

And no celebration of its two-year anniversary. I guess it wasn’t as much of a BFD as Joe Biden said it was. Or perhaps it is, but not in the way he thought.

Happy second birthday, ObamaCare! “Now let’s destroy it, root and branch.”

the Democrats (politically) got wrong on ObamaCare. Did they get anything right?

Heh: “Democrats so misjudged everything about Obamacare, you would think they never read the bill or something.”
