New cancer vaccine may tackle HER2-positive tumors

In In The News by Barbara Jacoby

By: Ana Sandoiu From: medicalnewwstoday.com New research shows that a new cancer vaccine may be effective for treating a range of HER2-positive cancers, including the more aggressive HER2-positive breast cancer. Cancer that is human epidermal growth factor 2 (HER2)-positive holds too much of the protein on the surface of its cells. In HER2’s role as a growth factor, normal levels …

Cancer: Scientists reveal how to boost radiotherapy

In In The News by Barbara Jacoby

By: Catharine Paddock PhD From: medicalnewstoday.com Scientists have recently identified a molecular pathway that links the movement of energy-producing centers, or mitochondria, in cancer cells to resistance to radiotherapy. This, they say, could lead to improved cancer treatments. Although previous studies had already revealed that the pathway — called Arf6-AMP1-PRKD2 — plays a key role in cancer invasiveness, its relation to treatment resistance …

New cancer vaccine is 100 percent successful in mouse model

In In The News by Barbara Jacoby

By: Maria Cohut From: medicalnewstoday.com Scientists have developed a new vaccine that — in conjunction with existing therapies — can not only treat aggressive melanoma, but also prevent its recurrence. Researchers from the Scripps Research Institute in San Diego, CA, recently worked with experts from other institutions to develop a vaccine that would be effective against melanoma (a type of skin cancer) when administered …

Primary breast cancer can ‘shut down its own spread’

In In The News by Barbara Jacoby

By: Ana Sandoiu From: medicalnewstoday.com Breakthrough research shows that primary breast cancer has the ability to “essentially shut down its own spread.” These findings may help “freeze” cancer cells before they get chance to form secondary tumors. According to the National Cancer Institute (NCI), in the United States, a total of 266,120 women will be diagnosed with breast cancer in …

New chemical causes deadly brain cancer to self-destruct

In In The News by Barbara Jacoby

By: Ana Sandoiu From: medicalnewstoday.com Scientists have discovered a chemical compound that cuts off the “energy supply” to glioblastoma cells, making them self-destruct. Glioblastoma is a highly aggressive brain tumor. Glioblastoma is a deadly form of brain cancer. Glioblastoma tumors emerge from the sticky, supportive tissue of the brain, which gets an ample supply of blood. This makes the cancer …

How cells actively stop breast cancer from becoming invasive

In In The News by Barbara Jacoby

By: Ana Sandoiu From: medicalnewstoday.com A new study shows that the cells surrounding the breast’s milk ducts form an active barrier that extends and grabs cancer cells before they spread to the rest of the body. The American Cancer Society estimate that in 2017, there were over 310,000 new cases of breast cancer among American women. Of these, 63,410 women …

Bowel cancer: Low-calorie soft drinks could reduce recurrence

In In The News by Barbara Jacoby

By:  Catharine Paddock PhD From: medicalnewstoday.com Consuming artificially sweetened soft drinks such as diet colas may be linked to a significantly lower risk of cancer return or death in patients with stage 3 colorectal cancer. It is also likely that around half the effect is due to artificially sweetened options displacing sugar-sweetened ones. These were the conclusions of a study, which has …

Targeting the enzyme with a dual role in breast and brain health

In In The News by Barbara Jacoby

LBy: Maria Cohut From: medicalnewstoday.com The enzyme tousled-like kinase 2 maintains genome stability at cellular level. Researchers have also linked it to different health conditions, including breast cancer and intellectual disability. A new study now describes this enzyme’s structure, arguing that this will help to design better therapies. Tousled-like kinases are enzymes that play a complex role in preserving genome stability within …

Using cell metabolism to battle cancer

In In The News by Barbara Jacoby

By: Tim Newman From: medicalnewstoday.com By focusing on how cancer stem cells metabolize, researchers may have uncovered a new way to defeat them: by attacking their energy supply. Drug resistance is a sizable problem for cancer treatment. Medications that might initially work will soon become ineffective. Scientists from the University of Michigan Rogel Cancer Center in Ann Arbor are focusing on how cancer stem …

Is it possible to kill cancer by ‘overfeeding’ it?

In In The News by Barbara Jacoby

By: Maria Cohut From: medicalnewstoday.com Oxidative stress is a phenomenon that occurs at a cellular level, and which can drive previously healthy cells to deteriorate and eventually die. Cancer often uses oxidative stress to its own benefit, but could this phenomenon be turned against it? Reactive oxygen species (ROS) are substances that are produced naturally following the process of oxygen metabolism. …
