Immunotherapy, with a Side of Poo: How gut microbes influence cancer treatment

by Katherine J. Wu figures by Neal Atsuka Are we flushing the next big cancer treatment down the toilet? Probably not – but the contents of our feces could very well be influencing how our bodies respond to cancer drugs. As it turns out, everybody poops – and everybody poops more than poop. I’m talking, of course, about the gut microbiota – the enormous collection … Continue reading Immunotherapy, with a Side of Poo: How gut microbes influence cancer treatment

Cancer Vaccines: How scientists are turning cancer against itself

by Cathy Gutierrez figures by Lillian Horin “The history of cancer vaccines is a history of failure.” This is the leading sentence of a 2005 article that summarized the history of cancer vaccines. Cancer vaccines have long been the Holy Grail of cancer research. For centuries, scientists have been devising ways to train the body to destroy tumors. Despite the success of early preventive cancer … Continue reading Cancer Vaccines: How scientists are turning cancer against itself

Bacteria May Help Protect Cancer Cells

Developing cancer drugs is challenging. Often, scientists will find a drug that kills cancer cells in a petri dish but fails to act on an actual tumor. Ravid Straussman from the Weizmann Institute of Science and Todd Golub from Harvard Medical School think that in situ, bacteria can protect cancer cells from drugs. To test their theory, Staussman and Golub mixed some healthy skin cells with cells from a … Continue reading Bacteria May Help Protect Cancer Cells

Could Zika become a treatment for brain cancer?

Glioblastoma is one of the most deadly brain cancers because it is nearly impossible to destroy the cause of the cancer: cancerous stem cells. However, scientists are using Zika’s preference for stem cells to target and eliminate the cancerous stem cells in adults. The preliminary study shows the viability of this method, but more thorough research and a PR campaign may be necessary before Zika treatments for brain cancer can become standard protocol. Continue reading Could Zika become a treatment for brain cancer?

Catching Cancer: Blood Test for Early-Stage Diagnosis

What is the difference between a normal cell and a cancer cell? The answer lies in their DNA. Cancer results from the accumulation of genetic mutations, which trigger uncontrolled cell growth. Cancer’s mutated DNA can reveal its presence early on in the disease. Like leaving fingerprints at a crime scene, tumor cells release small pieces of DNA into the bloodstream. This “circulating tumor DNA” can now … Continue reading Catching Cancer: Blood Test for Early-Stage Diagnosis

Turning the Immune System into an Equal Opportunity Cancer Killer

Results from a small clinical trial comprising 86 cancer patients have prompted scientists to rethink how different cancers are classified and treated. The drug being assessed was Keytruda, a recent addition to oncologists’ arsenal of cancer immunotherapy drugs.  Unlike traditional chemotherapies, which poison and kill cancer cells directly, cancer immunotherapy recruits the body’s own self-defense machinery to attack tumors.  Although our immune systems are very good … Continue reading Turning the Immune System into an Equal Opportunity Cancer Killer

Cancer Moonshot Musings II: Fusion oncoproteins in focus

by Steph Guerra figures by Shannon McArdel The Cancer Moonshot is an initiative that was launched by Joe Biden in 2016 with the goal of accelerating cancer research progress by bringing together world-class researchers and institutions in the battle against this disease. Armed with $300 million in startup funding, plus a total of $1.8 billion authorized over the next seven years, the Cancer Moonshot has … Continue reading Cancer Moonshot Musings II: Fusion oncoproteins in focus

Cancer Immunotherapy: Fighting fire with fire

by Kimberly Hagel figures by Alexandra Was We, as humans, tend to idealize that which is bigger, better, faster, and stronger. It is in our nature to strive towards the best. To improve. To win. Indeed, the penetrance of this mentality reaches to our very core, even to the individual cells of which we are composed. A prime example of this: cancer. Today, cancer is … Continue reading Cancer Immunotherapy: Fighting fire with fire

Microbial Physicians: Delivering drugs with bacteria

by Benika Pinch Fancy a pill packed with bacteria? Researchers are investigating using genetically modified bacteria, taken in pill form, to treat human disease. Informally, they are called “designer probiotics”. But, unlike probiotics (microorganisms with known health benefits), they can’t be obtained via a serving of yogurt from your local supermarket. Rather, the bacteria in question are feats of genetic engineering and are specifically designed … Continue reading Microbial Physicians: Delivering drugs with bacteria

Diabetes, Cancer and the Drug that Fights them Both

by Megan L Norris figures by Bradley Wierbowski The emerging link between cancer and diabetes In the early 2000s, observations that diabetics are more likely to get cancer than non-diabetics began piling up. Was this because diabetes and cancer share general risk factors such as diet, aging and obesity? Or was there a direct link between them, with cancer benefiting from the sugar-rich and inflamed … Continue reading Diabetes, Cancer and the Drug that Fights them Both
