How a Single, Genetic Change Causes Retinal Tumors in Children

September 26, 2014 8:30 am | News | Comments

New research has answered the long-standing question of why mutations to the RB1 gene primarily cause tumors of the retina and not of other cell types. The study could reveal new cellular signaling pathways relevant to retinal development, cancer development, and ultimately, the development of novel therapies.

Pancreatic Cancer Insight

September 25, 2014 8:30 am | News | Comments

An analysis of circulating tumor cells (CTCs) in a mouse model of pancreatic cancer has identified distinct patterns of gene expression in several groups of these cells, including significant differences from the primary tumor that may contribute to their ability to spread.

Gene Linked to Development of Skin Cancer in Mice

September 23, 2014 1:52 pm | News | Comments

New research on an enzyme linked to cancer development shows that 37 percent of mice that produce excessive quantities of the enzyme developed skin tumors within four to 12 months of birth, and many of these growths progressed to highly invasive squamous cell carcinoma, a common form of skin cancer.

Abnormal Properties of Cancer Protein Revealed in Fly Eyes

September 17, 2014 12:44 pm | News | Comments

Mutations in the human retinoblastoma protein gene are a leading cause of eye cancer. Now, scientists have turned to fruit fly eyes to unlock the secrets of this important cancer gene.                   

Clues Explain How Breast Implants May Cause Lymphoma

September 16, 2014 2:58 pm | News | Comments

Researchers have identified clues to explain how breast implants may, on very rare occasions, contribute to the development of lymphoma. There have been 71 known cases worldwide of a type of blood cancer called anaplastic large cell lymphoma (ALCL) that the researchers suggest were associated with the patient's breast implants.

New Knowledge of Genes Driving Bladder Cancer Points to Targeted Treatments

September 15, 2014 1:08 pm | News | Comments

The story of cancer care seems so simple: find the mutated gene that causes cancer and turn it off or fix it. But rarely does a single gene cause cancer. More often, many genes are altered together to drive the disease. So the challenge becomes sorting out which altered genes are the most to blame in which cancers. A new study takes an important step toward answering this question in bladder cancer.

Study Links Genetic Mutation to Melanoma Progression

September 11, 2014 3:45 pm | News | Comments

Researchers have found that the genetic mutation BRAFV600E , frequently found in metastatic melanoma, not only secretes a protein that promotes the growth of melanoma tumor cells, but can also modify the network of normal cells around the tumor to support the disease's progression.

‘Electronic Skin’ Could Improve Early Breast Cancer Detection

September 10, 2014 11:27 am | News | Comments

For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an “electronic skin” that “feels” and images small lumps that fingers can miss.            

Team Finds Ovarian Cancer Oncogene in 'Junk DNA'

September 9, 2014 3:43 pm | News | Comments

Over the years researchers have made tremendous strides in the understanding and treatment of cancer by searching genomes for links between genetic alterations and disease. Now, a team of researchers has mined "junk DNA" sequences to identify a non-protein-coding RNA whose expression is linked to ovarian cancer.

Breaking News: Prediabetes Ups Cancer Risk 15%

September 9, 2014 9:04 am | News | Comments

A meta-analysis comprising 16 studies and 891,426 participants from various regions of the world shows that prediabetes increases the risk of cancer by 15 percent, with differing risks depending on the type of cancer.

Scanner Could Aid Brain Tumor Removal, Reduce Recurrence

September 3, 2014 2:13 pm | News | Comments

Cancerous brain tumors are notorious for growing back despite surgical attempts to remove them. But scientists are currently developing a new way to try to root out malignant cells during surgery so fewer or none get left behind to form new tumors.

Double Mastectomy Doesn't Boost Survival for Most

September 2, 2014 4:23 pm | by Lindsey Tanner - AP Medical Writer - Associated Press | News | Comments

Removing both breasts to treat cancer affecting only one side doesn't boost survival chances for most women, compared with surgery that removes just the tumor, a large study suggests.                    

CTC Clusters More Likely to Cause Metastasis

August 29, 2014 8:30 am | News | Comments

Circulating tumor cell clusters- clumps of from two to 50 tumor cells that break off a primary tumor and are carried through the bloodstream- appear to be much more likely to cause metastasis than are single CTCs, according to a new study.    

Tomato-rich Diet Can Cut Prostate Cancer Risk

August 27, 2014 12:47 pm | News | Comments

Men who eat over 10 portions a week of tomatoes have an 18 per cent lower risk of developing prostate cancer, new research suggests. This is the first study of its kind to develop a prostate cancer "dietary index."         

Cancer Leaves a Common Fingerprint on DNA

August 26, 2014 1:45 pm | News | Comments

Regardless of their stage or type, cancers appear to share a telltale signature of widespread changes to the so-called epigenome, according to a team of researchers. In a study of a broad variety of cancers the investigators say they have found widespread and distinctive changes to chemical marks known as methyl groups attached to DNA.
