The benefits of detecting and treating cancer at early developmental stages have long been observed by clinical oncologists. Colonoscopies as well as other methods for early detection have been estimated to prevent as many as 60% of deaths attributable to colorectal cancer by identifying and removing precancerous growths1. More broadly, patients with early stage cancer(...)

Cancer and the Mutation Paradox
Posted by | Perspectives in ResearchIt has long been known — thanks largely to work by Johns Hopkins’ own Bert Vogelstein — that cancer is a disease generally caused by an accumulation of genetic mutations. This is sometimes referred to as the somatic mutation theory.1 This hypothesis states that each time a cell divides and grows, there are opportunities for(...)
Engineering Magic Bullets for Pancreatic Cancer
Posted by | Perspectives in ResearchIn a 1909 manuscript titled “Ueber den jetzigen Stand der Chemotherapie” (“About the Current State of Chemotherapy”), Nobel laureate Paul Ehrlich proclaimed, “We must learn to aim in a chemical sense.” What did he mean? Ehrlich was referring to his “magic bullet” theory of chemical specificity, the observation that certain drugs can eliminate disease-causing entities(...)
The Colorful World of Cancer Drug Discovery
Posted by | Perspectives in ResearchMelanoma cells stained with PTRF (in red), RPA194 (in green) and nucleus stained in blue. RPA194 is the main subunit of the RNA polymerase I (POL 1) enzyme. Our lab discovered a first-in-class small molecule that inhibits POL 1 enzyme and causes the destruction of RPA194 protein. Here, we are investigating how these proteins are(...)
A Novel Cancer Immunotherapy Unveiled: Y-Traps
Posted by | Perspectives in ResearchThe human immune system is composed of a diverse array of cells, which collectively work to exterminate pathogenic entities in the body. Yet this system is able to recognize host, or self, tissues as “friendly” through a variety of so-called immune checkpoint signals. Many cancer types — including melanomas and breast cancers — exploit this(...)
Advancing Glioblastoma Research: A Tale of Two Superheroes
Posted by | Perspectives in ResearchGlioblastoma research is similar to superhero film plots. How, you may ask? If each superhero represents a different treatment drug, then we as researchers want to cause destruction of the cancer cells with the least number of superheroes possible. This is because we wouldn’t want patients to need to take a large cocktail of treatments(...)
A New Blood Test Tries to Detect Cancer Sooner
Posted by | Perspectives in ResearchA patient develops symptoms that cannot be explained. The doctor orders a myriad of tests to discern the cause. If cancer is suspected, the patient may go through a painful and sometimes invasive biopsy procedure to sample the tissue in question. But what if a simple blood draw could be used instead? This is the(...)
Using Epigenetics to Fight Tumors
Posted by | Perspectives in ResearchWhile the word cancer treatment may identify everything from chemotherapy to radiation, there is significant variance between the type of cancer and its responsiveness to even the most promising therapies. That has been precisely the case for the α-PD-1 immunotherapy treatment. While it has shown remarkable efficacy in patients diagnosed with lung cancer, other types(...)
McCain and Brain Cancer: What’s in Store for Glioblastoma Treatment?
Posted by | Perspectives in ResearchIn the midst of the political saga that is the ongoing debate over the repeal of the Affordable Care Act (ACA), news broke that Sen. John McCain was undergoing surgery to remove a clot within his brain. After much media speculation and drama surrounding the delayed ACA vote, the public discovered that McCain had been(...)
When It Hits Too Close to Home
Posted by | A Day in the LifeI am equal parts excited and filled with dread as I open the door. The operating room is abuzz with activity, everyone hurriedly working to complete their duties during the operation. I focus on keeping out of the way of the ordered disorder, and avert my eyes from the patient on the operating table. I(...)
