‘Random’ Cell Movement is Directed from Within

October 21, 2013 1:23 pm | News | Comments

Cell biologists have teased apart two integral components of the machinery that causes cells to move. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell.

Database of Disease Genes IDs Drug Therapies

October 15, 2013 11:37 am | News | Comments

 Researchers have created a massive online database that matches thousands of genes linked to cancer and other diseases with various drugs that target those genes.                       

Thermodynamics May Help to Better Understand Cancers

October 15, 2013 11:26 am | News | Comments

In a new study, researchers used a gene-array analysis known as "surprisal analysis," which uses the principles of thermodynamics, to identify cancer-specific gene signatures for breast, lung, prostate and ovarian cancers in more than 2,000 patients.

Football-shaped Particles Bolster the Body's Defense against Cancer

October 14, 2013 10:42 am | News | Comments

Researchers at Johns Hopkins have succeeded in making flattened, football-shaped artificial particles that impersonate immune cells. These football-shaped particles seem to be better than the typical basketball-shaped particles at teaching immune cells to recognize and destroy cancer cells in mice.

Compound in Grapes, Red Wine Could Help Treat Multiple Types of Cancer

October 14, 2013 10:06 am | Videos | Comments

A recent study by a University of Missouri researcher shows that resveratrol, a compound found in grape skins and red wine, can make certain tumor cells more susceptible to radiation treatment. This research, which studied melanoma cells, follows a previous MU study that found similar results in the treatment of prostate cancer.


Cancer-fighting Gene in Blood Controlled by RNA

October 11, 2013 12:03 pm | News | Comments

A gene that helps keep blood free of cancer is controlled by tiny pieces of RNA, a finding that may lead to better ways to diagnose blood cancers and even lead to new forms of treatment, researchers report.             

DNA Repair Molecule Helps Prevent Brain Tumors

October 11, 2013 11:49 am | News | Comments

A molecule originally implicated in DNA repair may also be a crucial factor in preventing tumors such as medulloblastoma, a type of childhood brain tumor, according to new research.                   

Multivitamins May Protect Against Breast Cancer Death

October 9, 2013 1:03 pm | News | Comments

Findings from a study involving thousands of postmenopausal women suggest that women who use supplements containing both multivitamins and minerals have a 30 percent lower risk of dying from invasive breast cancer when compared with nonusers.

Good Cholesterol May Increase Breast Cancer Risk

October 9, 2013 11:42 am | News | Comments

High levels of HDL have been linked to increased breast cancer risks and to enhanced cancer aggressiveness in animal experiments. Now, a team of researchers has shown that an HDL receptor found on breast cancer cells may be responsible for this effect.

Tumors, Saliva Exchange Cellular Signals

October 9, 2013 11:36 am | News | Comments

Pancreatic cancer is typically diagnosed through an invasive and complicated biopsy. Now, in a study on a tumor-ridden mouse model, researchers were able to definitively validate that pancreatic cancer biomarkers reside in saliva.    

Sunscreen Saves 'Superhero' Gene

October 8, 2013 12:10 pm | News | Comments

A world-first human study to assess the impact of sunscreen at the molecular level has shown that sunscreen provides 100 percent protection against all three forms of skin cancer, and it also shields the important p53 gene, a gene that works to prevent cancer.

Drug Can Target Deadly Breast Cancer

October 4, 2013 1:40 pm | News | Comments

Often deadly “triple-negative” breast cancers might be effectively treated in many cases with a drug that targets a previously unknown vulnerability in the tumors, according to a new study.  Researchers found blocking cystine from entering triple-negative breast cancer cells can significantly inhibited their growth in culture and when the cancer cells were transplanted into mice.

'Junk' DNA Reveals New Disease-causing Mutations

October 4, 2013 12:22 pm | News | Comments
