... Institute of Neurological Disorders and Stroke, a division
of the National Institutes of Health. Understanding the role of cln3 has implications beyond juvenile Batten disease a rare, untreatable disorder -- because the protein is overproduced by cells in a number of cancers. And the lipid transported by cl...
Researchers discover why mutant gene causes colon cancer
...he APC gene did that it regulated cell growth and division
but now we know we've been missing a big piece of the picture," reports David Jones, Ph.D., principal investigator of the study and leader of HCI's Colon Cancer Scientific Program. "What we didn't know was that it converts vitamin A into retinoic ac...

...al BMPs play a role in enhancing the rates of cell division
and growth and regulating major developmental events including bone differentiation. Deregulation of BMP pathway activity has also been linked to some tumor growth. To test whether or not BMP4 is indeed a growth mediator, they used techniques from ge...
Skin stem cells give hairless mice hair

Anticancer drug zebularine specifically targets tumor cells
.... In a study of zebularine's effect on the rate of division
of cancer cells, Jones and colleagues showed that zebularine slows growth by as much as 68 percent in cancer cells, but only by 21 percent or less in normal cells. These findings were reported in the August 2004 issue of Cancer Cell . Only recently ...

in its tracks," he said. OSU 111 induces apoptosis cell suicide in cancer cells because it keeps key structures called microtubules from working during cell division. Microtubules distribute chromosomes to new cells. OSU 111 also prevents tumor cel...
