Study Suggests Vitamin D Screening And Appropriate Supplementation Indicated For All Cancer Patients
Vitamin D deficiency was found to be prevalent in cancer patients regardless of nutritional status, according to the results of a recent study conducted at Cancer Treatment Centers of America (CTCA). Based on these results, CTCA researchers determined that screening for vitamin D deficiency and aggressive vitamin D repletion should be considered for all people with cancer.

Supreme Court Should Be 'Reined In' To Return Power To Legislative Branch, NYT Columnist Writes
Although Supreme Court nominee Sonia Sotomayor"s confirmation hearings are more than a month away, "it"s easy to predict how they will go," New York Times columnist Ross Douthat writes. Douthat predicts that Senate Judiciary Committee members "will attempt to divine Sotomayor"s position on a variety of controversial topics," such as abortion rights, and in "a series of polite, evasive answers, the nominee will feign a studious neutrality on almost every issue that could come before her during what"s likely to be decades as one of the most powerful women in the world." According to Douthat, the "deeper stakes" that likely will be ignored are that "Sotomayor will be joining a high court that"s gradually become a kind of extra legislative body." He cites research from Harvard Law School professor Jed Shugerman showing that the court over roughly the past 50 years has invalidated both state and federal statutes at an unprecedented rate. Douthat also points to data from Evan Caminker of the University of Michigan showing that in one eight-year period, the court invalidated 16 federal laws in 5-4 votes, something that occurred only 25 times in the previous two centuries. Douthat writes that "settling so many vexing controversies with 5-to-4 votes -- effectively making Anthony Kennedy the nation"s philosopher king -- is an awfully poor way to run a republic."Douthat continues that the "modern court"s most enduringly controversial power grabs -- with Roe v. Wade leading the way -- were usually the work of liberal justices" but that "in practice, the main divide between liberal and conservative judges tends to be over the responsibilities of the federal government, not judicial activism per se." He writes, "There are bipartisan ways that the Court could be reined in, and the legislative branch reinvigorated," including the idea of a supermajority rule that would require a 6-3 vote to overturn federal legislation. This idea "might spur the court toward greater consensus, and perhaps greater modesty as well," according to Douthat. Another possibility would be to implement 12-year term limits, he says. Douthat concludes that these suggestions would not "reduce the Supreme Court"s power directly, but it would help us see the court for what it has become -- a deeply political institution, as fallible as any other, and answerable, when all is said and done, to us" (Douthat, New York Times, 6/2).

Genistein Targets MEK4 In Human Prostate Cancer Cells

Researchers have identified MEK4 as a pro-invasion protein and the target for genistein, a dietary compound, in prostate cancer cells, according to a new study published online July 28 in the Journal of the National Cancer Institute. Li Xu, M.D., Ph.D., and Raymond C. Bergan, M.D., of the Department of Medicine at Northwestern University in Chicago, and colleagues investigated the target for genistein in prostate cancer cells by assessing cell invasion and gene and protein expression of mitogen-activated protein kinase 4 (MEK4) and matrix metalloproteinase-2 (MMP-2), which is associated with cell invasion. Overexpression of MEK4 increased MMP-2 expression and cell invasion in prostate cancer cells; decreased MEK4 expression had the opposite effect. Computer modeling showed that genistein could bind to the active site of MEK4, and an enzymatic assay showed that genistein inhibited MEK4 kinase activity. The MMP-2 transcript level was statistically significantly higher in normal prostate epithelial cells, which are target cells for chemoprevention, from untreated patients with prostate cancer than from genistein-treated patients. "Thus, we have shown that it is possible to target motility-associated processes with genistein in patients with prostate cancer, have identified MEK4 as the therapeutic target for genistein in all six prostate cell lines examined, and have provided a possible mechanism to link high dietary consumption of genistein-containing foods with lower rates of prostate cancer metastasis and mortality," the authors write.
