US cervical cancer rates higher than previously reported, especially among older women
Cervical cancer rates in the United States are higher than previously believed, particularly among 65- to 69-year-old women and African-American women, according to a study led by a researcher at the University of Maryland School of Medicine published in the journal Cancer. Current US cervical cancer screening guidelines do not recommend routine Pap smears for women over 65 if their prior test results have been normal.

Revealed:Protein's role in preventing heart muscle growth leading to heart failure
Hebrew University Faculty of Medicine researchers showed for the first time that the protein Erbin is an important brake that helps prevent pathological cardiac hypertrophy. They showed that damage to this protein leads to excess growth of heart muscle, a decrease in function, and severe pathological growth of heart muscle. Their research has implications for breast cancer treatment, as Erbin interacts with the receptor Her2/ErBb2, which is overexpressed in approximately 30 percent of breast cancers.

Properties of water at nanoscale will help to design innovative technologies
Scientists from Politecnico di Torino (Turin, Italy) and Houston Methodist Research Institute (Houston, USA) have just proposed on Nature Communications a novel understanding of unexpected water properties at the nanoscale in the close proximity of solid surfaces. More rationally designed contrast agents for improved Magnetic Resonance Imaging performances are the first applications of the discovery.

New method sneaks drugs into cancer cells before triggering release
Biomedical engineering researchers have developed an anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened to keeping a cancer-killing bomb and its detonator separate until they are inside a cancer cell, where they then combine to destroy the cell.

Discovery links rare, childhood neurodegenerative diseases to common problem in DNA repair
St. Jude Children's Research Hospital scientists studying two rare, inherited childhood neurodegenerative disorders have identified a new, possibly common source of DNA damage that may play a role in other neurodegenerative diseases, cancer and aging. The findings appear in the current issue of the scientific journal Nature Neuroscience.

New paper provides important insights into carcinoma-associated fibroblasts
A new paper by a team of researchers led by Zachary T. Schafer, Coleman Assistant Professor of Cancer Biology in the Department of Biological Sciences at the University of Notre Dame, offers important new insights into the role carcinoma-associated fibroblasts (CAFs) play in tumor biology. A number of recent studies have revealed CAFs to be a major contributor to tumor progression through a variety of mechanisms. Despite this information, the precise role CAFs play in augmenting the growth of tumors is still poorly understood.

New technology using florescent proteins tracks cancer cells circulating in the blood
After cancer spreads, finding and destroying malignant cells that circulate in the body is usually critical to patient survival. Now, researchers reporting in the Cell Press journal Chemistry & Biology have developed a new method that allows investigators to label and track single tumor cells circulating in the blood. This advance could help investigators develop a better understanding of cancer spread and how to stop it.

Exact outline of melanoma could lead to new diagnostic tools, therapies
Researchers have identified a specific biochemical process that can cause normal and healthy skin cells to transform into cancerous melanoma cells, which should help predict melanoma vulnerability and could also lead to future therapies. They discovered in this situation that the immune system is getting thrown into reverse, helping to cause cancer instead of preventing it.

Few women at high-risk for hereditary breast and ovarian cancer receive genetic counseling
Mutations in the BRCA1 and BRCA2 genes account for nearly 25 percent of hereditary breast cancers and most hereditary ovarian cancers, yet a study by cancer prevention and control researchers at Virginia Commonwealth University Massey Cancer Center suggests an alarmingly small amount of women who qualify for BRCA genetic counseling actually receive the services. Additionally, they found that a significant proportion of women with a family history of breast and ovarian cancer underestimate their risk.

Honolulu-based study reveals shorter men live longer
Short height and long life have a direct connection in Japanese men, according to new research based on the Kuakini Honolulu Heart Program and the Kuakini Honolulu-Asia Aging Study. Shorter men are more likely to have a protective form of the longevity gene, FOXO3, leading to smaller body size during early development and a longer lifespan. Shorter men are also more likely to have lower blood insulin levels and less cancer.

Ovarian cancer cells are more aggressive on soft tissues
When ovarian cancer spreads from the ovaries it almost always does so to a layer of fatty tissue that lines the gut. A new study has found that ovarian cancer cells are more aggressive on these soft tissues due to the mechanical properties of this environment. The finding is contrary to what is seen with other malignant cancer cells that seem to prefer stiffer tissues.
