An investigative drug deprived non-Hodgkin lymphoma cells of their ability to survive too long and multiply too fast, according to an early study published recently in the journal Experimental Hematology.
CLEVELAND -- Nanoscopic tubes made of a lattice of carbon just a single atom deep hold promise for delivering medicines directly to a tumor, sensors so keen they detect the arrival or departure of a single electron, a replacement for costly platinum in fuel cells or as energy‐saving transistors and wires.
Cytokines are small proteins secreted by cells that serve as molecular messengers between cells. Pro-inflammatory cytokines -- which function in the immune system -- may be involved in alcohol dependence (AD).
Researchers at the Johns Hopkins School of Medicine have discovered how one antioxidant protein controls the activity of another protein, critical for the development of spinal cord neurons. The research, publishing this week in Cell, describes a never-before known mechanism of protein control.
The Stowers Institute's Baumann Lab has demonstrated how human cells protect chromosome ends from misguided repairs that can lead to cancer. The work, published in The EMBO Journal, a publication of the European Molecular Biology Organization, follows the team's 2007 in vitro demonstration of the role of the hRAP1 protein in preventing chromosome ends from being fused to new DNA breaks.
HERSHEY, PA -- Penn State College of Medicine researchers, in collaboration with colleagues at the University of Southern California, have taken an important step in understanding the role of stem cells in development of liver cancer. Using a unique approach that involves study of individual cells, the team, led by C.
Like vampires, cancer tumors require an ample supply of blood to stay alive. Without fresh blood for sustenance, cancer cells shrivel up like raisins and die.
UCSF researchers have identified collections of tiny molecules known as microRNAs that affect distinct processes critical for the progression of cancer. The findings, they say, expand researchers' understanding of the important regulatory function of microRNAs in tumor biology and point to new directions for future study and potential treatments.
LA JOLLA, Calif., September 15, 2009 -- Researchers at the Burnham Institute for Medical Research (Burnham) have discovered that reactive oxygen species, such as superoxide and hydrogen peroxide, play a key role in forming invadopodia, cellular protrusions implicated in cancer cell migration and tumor metastasis.
CHICAGO -- In patients with recent onset type-2 diabetes, treatment with insulin or the diabetes drug metformin did not reduce inflammatory biomarkers, such as high-sensitivity C-reactive protein, although the treatment did improve glucose control, according to a study in the September 16 issue of JAMA.

1. Three Medications Reduce the Risk for Invasive Breast Cancer but Carry Heavy Risks for Adverse Events
HOUSTON - Primary lung cancer shifts to metastatic disease by suppressing a family of small molecules that normally locks the tumor in a noninvasive state, researchers at The University of Texas M. D. Anderson Cancer Center report in the Sept. 15 edition of Genes and Development.
CHAPEL HILL -- Researchers at the University of North Carolina at Chapel Hill School of Medicine and the College of Arts & Sciences have identified a new biological process that spurs the growth of new blood vessels.
Washington, DC -- With the goal of tailoring cancer interventions for the individual, researchers at the Lombardi Comprehensive Cancer Center at Georgetown have published the results of a prospective study that validates the use of a simple blood test to help doctors more reliably assess treatment effectiveness for patients with metastatic breast cancer.
PHILADELPHIA -- In a one-two punch, a familiar diabetes drug reduced tumors faster and prolonged remission in mice longer than chemotherapy alone by targeting cancer stem cells, Harvard Medical School researchers reported in the September 14 online first edition of Cancer Research, a journal of the American Association for Cancer Research.
