Reactivation of a single gene turns colorectal cancer cells back into normal tissue

By - June 23, 2015 2 Pictures

Future cancer treatments may target your genes rather than the cancerous cells themselves. A new study found that reactivating a single gene was enough to stop and reverse colorectal cancer (that's cancer of the colon, or bowels) in mice, with a return to normal intestinal functions within just four days and tumors gone within two weeks. The concept, though not the specific method, could lead to new treatments of a variety of cancers.

Nanorobots wade through blood to deliver drugs

By - June 17, 2015

Nanorobots hold great potential in the field of medicine. This is largely due to the possibility of highly-targeted delivery of medical payloads, an outcome that could lessen side effects and negate the need for invasive procedures. But how these microscopic particles can best navigate the body's fluids is a huge area of focus for scientists. Researchers are now reporting a new technique whereby nanorobots are made to swim swiftly through the fluids like blood to reach their destination.

Vaccine-style treatment for rheumatoid arthritis retrains the immune system

By - June 4, 2015 2 Pictures

According to the American College of Rheumatology, more than one million Americans suffer from rheumatoid arthritis. The disease gives rise to swelling and pain by causing the immune system to malfunction and attack healthy tissue. No cure is available, though aggressive and varied drug treatments can curb its effects. Now, success in an early clinical trial suggests that a new form of therapy could stop these symptoms taking hold by retraining the patient's immune system to ignore a peptide it normally identifies as a foreign foe.

Herpes virus genetically engineered to destroy skin cancer cells

By - May 27, 2015

A new study has pointed to a chink in the armor of skin cancer cells, suggesting that they can be overpowered by the body's own system with help from a pioneering approach known as viral therapy. A clinical trial has demonstrated that a genetically engineered herpes virus can not only plant itself in the cancer cells and kill them off, but activate the body's own immune system to stave off harmful tumors.
