The essence of this finding is a series of molecular events that enable communication inside cells between the nucleus and mitochondria. …
Seven hundred patients treated for colorectal cancer at three Cancer Treatment Centers of America hospitals completed service quality questionnaires measuring their levels of satisfaction with hospital operations and services, physicians and staff, and contained patient endorsements. Overall patient experience was measured by asking, “Considering everything, how satisfied are you with your overall experience with the institution?” Survey responses were correlated with median patient survival time from survey completion…
By examining both viral amino-acid sequences and the animals’ immune responses, the scientists could determine the mechanisms of protection from SIV infection. The study demonstrated that antibodies to the virus spikes that SIV uses to infect cells are necessary and sufficient to prevent SIV infection. The study also identified clear measures of immune responses in monkeys that predict protection from SIV infection. Amid the genetically heterogeneous mix of SIV to which the vaccinated monkeys were exposed, vaccine-induced immune responses tended to block infection by those viruses sensitive to neutralization by SIV antibodies, while neutralization-resistant forms of SIV tended to cause infection. …
The rates of apoptosis, or programmed cell death, were higher in the mice treated with the experimental agent than in the untreated animals that also had high-grade glioblastomas, said Johanna Joyce, Ph.D., of the Memorial Sloan-Kettering Cancer Center (MSKCC) in New York City. …
Clinical Cancer Advances 2013: ASCO’s Annual Report on Progress Against Cancer reveals how marked expansion in our knowledge and understanding of cancer is already improving treatment while also pointing the way towards even more effective approaches in the future. Published today in the Journal of Clinical Oncology, the ASCO report covers a broad range of cancer types and highlights a selection of the most recent achievements across the entire continuum of cancer care, from prevention and screening to treatment and survivorship. "For patients today, these results can be critical. Scientifically, they demonstrate how our long term investment in science and technology can yield practical advances now and in the near future," said ASCO President Clifford A…
Women with a break in their insurance coverage had a 3.5-fold higher likelihood of nonconcordance with National Comprehensive Cancer Network (NCCN) guidelines for radiation therapy and chemotherapy compared with women with uninterrupted coverage. "We found that women who had no insurance at some point during treatment, women with lower incomes compared with those in the highest income categories, and women who held more debt at the time of diagnosis were less likely to receive all of the recommended breast cancer treatments," said Jean A…
Eight of the nine boys registered to date in the new trial are alive and well, with functioning immune systems and free of infections associated with SCID-X1, between nine and 36 months following treatment, according to Sung-Yun Pai, MD, a pediatric hematologist-oncologist from Dana-Farber/Boston Children’s Cancer and Blood Disorders Center. …
The study was published online November 30, 2013 in the Journal of the National Cancer Institute. …
Many mechanisms contribute to explain this effect called "acquired resistance," but today the group of Manel Esteller, Director of Epigenetics and Cancer Biology at the Bellvitge Biomedical Research Institute (IDIBELL), ICREA researcher and Professor of Genetics at the University of Barcelona, describes in the official Journal of the National Cancer Research Center in the United States, The Journal of The National Cancer Institute, the existence of epigenetic differences that explain the lack of response of the tumor recurs. "We studied colon cancer cells that were initially sensitive to oxaliplatin drug and then became insensitive to this drug and we found that resistant tumors had inactivated a gene (SRBC) in their DNA" says Manel Esteller "the loss of activity supposedly happens in a gene involved in DNA repair. Thus these tumor cells, when receiving the drug, quickly repair the effect thereof and do not die. Studying nearly two hundred patients with colon cancer also found that inactivation of the gene is associated with poorer survival of these people despite treatment. …
"We discovered that the enzyme USP13 stabilizes the PTEN protein by reversing a process that marks various proteins for destruction by the cell’s proteasome," said the paper’s senior author Li Ma, Ph.D., assistant professor of Experimental Radiation Oncology. "USP13 also suppresses tumor formation and glycolysis though PTEN," Ma said. Glycolysis is a glucose metabolism pathway that tumors rely on to thrive and grow…
