 Molecular TherapyNano drug crosses blood-brain tumor barrier, targets brain-tumor cells and blood vessels The blood-brain barrier protects the brain from poisons but also prevents drugs from reaching brain tumors. A preclinical study shows that an experimental nanotechnology drug called SapC-DOPS crosses the tumor blood-brain barrier, targets brain-tumor cells and retards growth of tumor blood vessels. The findings also show why the agent targets tumor cells and recommend the drug's further development as a novel treatment for glioblastoma.

Journal of the National Cancer InstituteEpoetin alfa reduces anemia in breast cancer patients with no negative impact on survival In patients with high-risk breast cancer, addition of the erythropoiesis-stimulating agent epoetin alfa to the chemotherapy regimen may help avoid the decrease in hemoglobin levels and resulting anemia often seen in these patients and does not negatively affect relapse-free or overall survival. However, it can increase the risk of thrombotic events, according to a study published July 17 in the Journal of the National Cancer Institute. Contact: Zachary Rathner

NatureMolecular switch controls the destiny of self-eating cells In a new paper published in the journal Nature, researchers present a previously unknown mechanism that controls whether a cell survives autophagy, a process that can be compared to the cell consuming parts of itself. The discovery means that it might now be possible to influence the process, which is involved in a wide variety of diseases. Contact: Dr. Bertrand Joseph

NatureProtein responsible for 'bad' blood vessel growth discovered The discovery of a protein that encourages blood vessel growth, and especially "bad" blood vessels -- the kind that characterize diseases as diverse as cancer, age-related macular degeneration and rheumatoid arthritis -- has been reported in the journal Nature.

MenopauseCancer survivors have more frequent and severe menopausal hot flashes Women who survive cancer have more frequent, severe, and troubling hot flashes than other women with menopausal symptoms, according to a study published online today in Menopause, the journal of The North American Menopause Society. But surprisingly, the cancer survivors fare better psychologically and report a better quality of life than the women without cancer and have about the same levels of sexual activity and function.

ACS NanoInjectable 'smart sponge' holds promise for controlled drug delivery Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells.

Journal of Molecular DiagnosticsRNA diagnostic test from paraffin improves lung cancer diagnosis over routine microscopic evaluation Scientists at the Universities of North Carolina and Utah have developed a histology expression predictor for the most common types of lung cancer: adenocarcinoma, carcinoid, small cell carcinoma and squamous cell carcinoma. This predictor can confirm histologic diagnosis in routinely collected paraffin samples of patients' tumors and can complement and corroborate pathologists' findings.

JAMAUse of ADT for treatment of prostate cancer linked with increased risk of kidney injury In a study that included more than 10,000 men with nonmetastatic prostate cancer, use of androgen deprivation therapy (ADT) was associated with a significantly increased risk of acute kidney injury, with variations observed with certain types of ADTs, according to a study in the July 17 issue of JAMA.

STI & AIDS World CongressStudy suggests STD clinics could reduce obstacles to much needed cervical cancer screenings A new study found that STD clinics could provide important access to cervical cancer screenings for women who traditionally have trouble receiving these screenings because of lack of insurance or other obstacles. Cervical cancer can be painful and deadly but can be effectively treated if caught soon enough. Yet in the US, reaching women who are underscreened for this cancer remains a public health challenge because insurance is the primary indicator for screening.

Molecular Biology of the CellSelf-perpetuating signals may drive tumor cells to spread A team of international researchers has identified a self-perpetuating signaling circuit inside connective tissue cells that allows these cells to form a front and a back and propel themselves in a particular direction over a long period of time. This propulsion is the same movement that tumor cells use to invade healthy tissue during cancer metastasis so cracking the code to this signaling network may lead to new therapeutic strategies.

ImmunityDiscovery of a new class of white blood cells uncovers target for better vaccine design Scientists at A*STAR's Singapore Immunology Network have discovered a new class of white blood cells in human lung and gut tissues that play a critical role as the first line of defence against harmful fungal and bacterial infections. This research will have significant impact on the design of vaccines and targeted immunotherapies for diseases caused by infectious microbes such as the hospital-acquired pneumonia.

Nature Cell BiologyMolecular relative of p53 tumor suppressor protein also helps cancer cells thrive The protein TAp73 is a relative of the well-known, tumor-suppressor protein p53, yet it is still not known whether TAp73 enhances tumor cell growth and, if so, exactly how. Penn researchers found that TAp73 supports the proliferation of human and mouse tumor cells. They also identify an important mechanism by which TAp73 gives tumor cells a growth advantage: it activates the expression of an enzyme important for cell replications and antioxidant protection.

eLifeProtecting the body in good times and bad The nasty side effects of radiation and chemotherapy are well known: Fatigue, hair loss and nausea, to name a few.

Hormones & CancerCommon autism supplement affects endocrine system Plant-based diets are healthy. Plants are high in flavonoids. So flavonoids are healthy. At least that's the reasoning of many manufacturers of flavonoid-based nutritional supplements. But a University of Colorado Cancer Center study published this week in the journal Hormones & Cancer shows that may not be the case. Flavonoids tested in the study affected the endocrine system in ways that in one case promoted cancer and in another repressed it. Contact: Garth Sundem

PLOS ONECSI-style DNA fingerprinting tracks down cause of cancer spread How do stationary cancer cells get the mutations that allow them to travel through the body to seed metastasis? Do they just grow these mutations themselves? Study shows that cancer cells fuse with blood cells -- which already can travel! -- to create a hybrid, metastatic cancer cell. Contact: Garth Sundem
