Protein may trigger cancer cell's metabolism
New research shows that a modified version of the protein Hsp90 that's known to trigger death in nervous system cells may actually help cancer cells.

Observing live energy production by malignant cells
To be able to function, cell mitochondria import 'fuel' using a carrier, the mitochondrial pyruvate carrier (MPC). In order to determine whether the MPC is still functional in malignant cells, scientists have just developed a biosensor to measure its live activity.

Scientists discover how key proteins segregate vital genetic information during mitosis
Chromosomes are responsible for carrying our genes and essentially protecting the information that helps ensure normal growth, with vital instructions being passed on by mitosis. While this copying mechanism has been well understood for decades, scientists have been unable to describe exactly how genetic information is protected and properly segregated as mitosis is happening. New research from the Wistar Institute has identified an interaction between proteins that provides a pivotal role in organizing chromosomes so that vital genetic information gets passed on safely.

New research tool tracks real-time DNA-protein binding in cells
Researchers have developed a new technology that precisely marks where groups of regulatory proteins called transcription factors bind DNA in the nuclei of live cells. Reporting their data Aug. 6 in the journal Molecular Cell, scientists at Cincinnati Children's Hospital Medical Center say the new technology -- called SpDamID -- could allow scientists to answer basic questions about tissue development and disease that existing technology cannot address.

Hypofractionation vs. Conventional fractionation in breast cancer radiotherapy
JAMA Oncology will publish two studies, a commentary and an author audio interview examining outcomes in women with breast cancer who had breast-conserving surgery and were treated with hypofractionated radiation therapy (shorter courses of radiation treatment administered in larger daily fraction sizes) compared with longer courses of conventionally fractionated radiation therapy.

Shorter course of radiation improves quality of life for breast cancer patients
Women who receive a shorter course of whole breast radiation therapy for early stage disease experience less toxicity and improved quality of life compared to those who undergo a longer course of treatment, researchers report from The University of Texas MD Anderson Cancer Center.

Neutrophil and cancer cell 'crosstalk' underlies oral cancer metastasis
An abnormal immune response or 'feedback loop' could very well be the underlying cause of metastases in oral cancers, according to Dr. Marco Magalhaes, Assistant Professor at the University of Toronto's Faculty of Dentistry. Magalhaes has unearthed a significant connection between the inflammatory response of a very specific form of immune cells, neutrophils, and the spread of this deadly disease.

Delay in treatment, missed diagnostic testing found among lung cancer patients
Patients undergoing surgery for lung cancer may wait too long to receive treatment, and too many patients skip vital diagnostic steps that are needed to help determine the best possible treatment, according to study published in the August 2015 issue of The Annals of Thoracic Surgery.

Penn study details powerful molecular promoter of colon cancers
Cancer researchers already know of some oncogenes and other factors that promote the development of colon cancers, but they don't yet have the full picture of how these cancers originate and spread. Now researchers have illuminated another powerful factor in this process, by unraveling an additional pathway for the origin of colon cancer.

Scientists solve structure of important protein for tumor growth
In a collaborative study between at Sanford Burnham Prebys Medical Discovery Institute and the Argonne National Laboratory, scientists have used a highly specialized X-ray crystallography technique to solve the protein structure of hypoxia-inducible factors, important regulators of a tumor's response to low oxygen.

Two-drug combination boosts survival in metastatic prostate cancer
Men with metastatic, hormone-sensitive prostate cancer gained more than a year of survival when they received both hormone-blocking medications and chemotherapy right after diagnosis, rather than delaying the chemo until the cancer worsened, according to a study led by Dana-Farber's Christopher Sweeney published in the New England Journal of Medicine.

Penn scientists identify key genetic factor that keeps moles from turning into melanoma
Moles are benign tumors found on the skin of almost every adult. Scientists have known for years that a mutation in the BRAF gene makes them start growing, but until now haven't understood why they stop. Now, researchers from the Perelman School of Medicine at the University of Pennsylvania have identified a major genetic factor that keeps moles in their usual non-cancerous, no-growth state.

Key protein drives 'power plants' that fuel cells in heart and other key body systems
Case Western Reserve University scientists have discovered that a protein called Kruppel-like Factor 4 (KLF4) controls mitochondria -- the 'power plants' in cells that catalyze energy production. Specifically, they determined KLF4's pivotal role through its absence -- that is, the mitochondria malfunction without enough of the protein, which in turn leads to reduced energy. The researchers' findings appear in the August edition of The Journal of Clinical Investigation.

Irradiation of regional nodes in stage I - III breast cancer patients affects overall survival
At a median follow-up of 10.9 years, an EORTC study has shown that irradiation of regional nodes in patients with stage I, II, or III breast cancer has a marginal effect on overall survival, the primary endpoint (at 10 years, overall survival was 82.3 percent for regional irradiation versus 80.7 percent for no regional irradiation).
