  • Failure Is Woven Into the Fabric of Obamacare

    Obamacare’s apologists, tired of being laughed at for claiming “it’s working,” have adopted a new talking point that they hope will produce less mirth. They now claim the law is such an integral part of our health care system that it is no longer susceptible to repeal or even revision. As President Obama recently put it, “This is now part of the fabric of how we care for one another.… This is health care in America.” This is a perfectly absurd claim to make about a law that has been in effect for only a year and a half. The...

    A newly published study shows that white blood cells and a cancer cells can fuse and initiate a tumor, providing the first proof in humans of a long proposed theory.Yale Cancer Center scientists, together with colleagues at the Denver Police Crime Lab and the University of Colorado, have found evidence that a human metastatic tumor can arise when a leukocyte (white blood cell) and a cancer cell fuse to form a genetic hybrid. Their study, published in the journal PLOS ONE, may answer the question of how cancer cells travel from the primary tumor’s site of origin to distant organs...

    Research could lead to new drug therapies to fight cancerRIVERSIDE, Calif. – Researchers at the University of California, Riverside have identified components in pomegranate juice that both inhibit the movement of cancer cells and weaken their attraction to a chemical signal that promotes the metastasis of prostate cancer to the bone. The research could lead to new therapies for preventing cancer metastasis. Performed in the lab of Manuela Martins-Green, a professor of cell biology, the research was presented today (Dec. 12, 2010) at the 50th annual meeting of the American Society for Cell Biology taking place in Philadelphia. Prostate cancer...
  • Mitochondrial Mutations Make Tumors Spread

    Cancer often strikes its final, fatal blow when a tumor spreads to other organs. A new study published online today in Science sheds light on this poorly understood process, called metastasis. The researchers report that mutations in mitochondrial DNA can spur metastasis and that it can be reversed with drugs, at least in mice. Mitochondria are the tiny organelles inherited from your mom that serve as the cell's powerhouses. They have their own DNA, called mtDNA. Ten years ago, cancer researchers noticed that mtDNA in tumor cells tends to be riddled with mutations--far more than in normal tissues. (This is...

    Researchers pinpoint protein 'boss' that controls gene expression. Link to Getty photo from a microscope Will it spread? One protein controls the expression of many genes that dictate whether breast cancer will metastasize. GettyA protein that determines whether breast cancer will spread and become deadly has been found. Researchers say that the protein, which is found inside the nuclei of cells, would be difficult and potentially dangerous to target with drugs. But monitoring for the protein could help patients to know how dangerous their cancer is before it spreads elsewhere, and help them to decide which treatment to chose. Because...

    Researchers say they have identified a switch that makes dormant breast cancer cells that have traveled to the lungs swell to lethal proportions—completing the dreaded process of metastasis or cancer spread. A team from Cold Spring Harbor Laboratory in Long Island, N.Y., reports that it staved off full-blown metastasis in mice by preventing mini-tumors in the lungs from recruiting stem cells called endothelial progenitors, which assemble into blood vessels to nourish the malignancy. Researchers do not know if the same thing would work for other types of cancer or cancer cells lodged in other body organs. Still, they hope to...
