Here at OncoBites, a team of graduate scientists and Ph.D.s with a passion for cancer research has gathered to share cutting-edge research with a wider audience. We understand that jargon and isolated professional communities have made science feel inaccessible to most people, even people considering the field. In addition, paywalls on articles can make trying…
Feeling the ‘heat’ from neighbors: Microenvironment driving cancers in the gut
Manisit Das Not long ago Tamara mentioned in her OncoBites article that it is often hard to determine what factors drive cancer. Even after a mutation responsible for fueling cancer growth is identified, we do not always know how that mutation contributes to tumor formation. Understanding these mechanisms is however quite important. As we gain…
Making cancer therapy smarter
Sara Musetti Last week on OncoBites, Beth Rogoski of PhDoodles shared with us the story of liquid biopsies, blood tests that can be used to detect cancer and evaluate treatments. Today, in a follow-up piece, we’ll go into more detail as to what technologies are making their way to market, how liquid biopsies can be…
It’s Time for New Blood in Cancer Medicine
Beth Rogoyski Most would consider a blood test a bit of a pain in the arm, but except for the fantastically needle-phobic, generally not something that would keep you awake at night. Contrast that to the sentiments that spring to mind when you hear the word chemotherapy, and the two couldn’t seem more dissimilar. Despite…
Expanding the network: new connections for an old driver in kidney cancer
Tamara Vital By now you’re probably noticing a running theme at OncoBites: cancer is complicated. Cancers have many moving parts, and despite our best efforts it can be difficult to know what factors drive them. Even when we have identified causal mutations in genes, it can be difficult to figure out how these mutations contribute…
From worms to cures
Emily B. Harrison, Ph.D Last month I attended the first RNA Therapeutics Conference held at University of Massachusetts Medical School. While I have attended several national conferences, this one beautifully encapsulated how basic science can lead to new drugs in only two decades. This conference inspired me to share with you the story of RNA…
Immune cells work together to enable successful cancer therapy
Morgan McSweeney A group of researchers from the University of California – San Francisco recently found that the presence of a certain group of immune cells in tumors (“stimulatory dendritic cells,” or SDCs) can predict better cancer outcomes, at least in melanoma patients. For example, in patients treated with checkpoint inhibitors (drugs that work by…
Stumbling before the beast: Not all cancer clinical trials end in drug approval
Manisit Das Since the beginning of OncoBites, we’ve talked a lot about immunotherapy: using our own immune cells to destroy the cancer cells? We can’t get enough of it! In one post, we highlighted a revolutionary approach recently approved by the US Food and Drug Administration (FDA) using genetically modified immune cells to fight cancer,…
Cancer-Curing Light
Sara Musetti The story of cancer is almost as old as the story of humans. As far back into ancient times as the 15th century BCE in Egypt, physicians have struggled to offer their patients any sort of relief from slowly spreading tumors. If tumors were visible to the naked eye–on the skin, breasts, neck,…
Where you live and how much money you make affects your likelihood of surviving cancer
Elizabeth Wayne, Ph.D. When we talk about cancer research we are probably just thinking about scientists in lab coats, gloves, and safety goggles looking at test tubes full of cancer cells. While this is true, cancer research doesn’t just happen in a test tube or broadly, in a laboratory. The practice of studying cancer from…
Bone found to abet Lung Cancer
Natasha Vinod Rudolph Virchow was one of the first physicians to study diseases from the standpoint of cells. He applied his cell theory “Omnis cellula e cellula” (“every cell originates from another cell”) to the study of cancer and reasoned that cancer results from the failure of the regulatory mechanism of the cells to control…
New frontiers in breast cancer management
Tamara Vital Over the last several decades, the survival rate for most kinds of breast cancer have increased due to earlier detection, new targeted therapies, and combination treatment modalities. As we’ve discussed before at Oncobites, cancer is not a single disease. It turns out that multiple distinct subtypes exist even within the category of “breast…
Cancer: a many headed beast
Emily B. Harrison, Ph.D. Every year more than one million women are diagnosed with breast cancer. Tumors are most often discovered through screening techniques like self-checks, breast exams, or mammograms. Immediately, plans are made to extract the tumor either by removing a small area around the tumor, a lumpectomy, or the entire breast in a…
The Immune Landscape of Cancer
Morgan McSweeney Cancer is not a single disease. It is a broad term that describes a number of related conditions in which cells’ growth has begun to bypass the usual checks and balances. To study the spectrum of cancers, the National Institutes of Health have established The Cancer Genome Atlas (TCGA), a collaborative project aimed…
Immunotherapy in Pancreatic Cancer: Does Bacteria hold the answer?
Manisit Das Your gut is crawling with bacteria, despite your devoted hygiene practices. Disgusting for your sophisticated self, isn’t it? Surprising as it is, over the course of evolution our bodies tolerated the microbial communities in our body, even cherished them. Hundreds of thousands of bacteria and other microorganisms call us home and play a…
Cancer Vaccines: Educating Your Immune System Since the 1800s
Sara Musetti Historians love to say that those who do not know their history are doomed to repeat it. In science, failing to remember and understand our history means that we may need to make the same discoveries again and again. This appears to be the case for cancer immunotherapy, a new branch of research…
We’ve got a new FDA Approved Immunotherapy: How does it work?
Elizabeth Wayne, PhD Everything you need to fight cancer is inside of you. Well sort of. This is the inspirational way that I like to think of cancer immunotherapy. It’s using your own immune cells to fight cancer. We do this by trying to get immune cells to recognize cancer as a foreign pathogen, thereby…
Cancer Epigenetics: More Twists and Turns in Tumors
Tamara Vital We’re still just getting started here at Oncobites, but the story is already clear: Cancer is complicated. So far Morgan has covered the underlying risk factors of cancer— the environmental and lifestyle factors that influence cancer development. Sara has explained that cancer arises in cells that acquire mutations in the genes that control…
In cancer, your own lymph nodes turn against you
Emily B. Harrison, PhD Perhaps the only time most people consider their lymph nodes is at a doctor’s office. Often, when examining you, a physician will touch the sides of your neck, feeling for enlarged lymph nodes. In this case, swollen nodes indicate that your body is mounting an immune response. This immune response is…
What exactly is cancer?
Sara Musetti I came to a realization this week. Here at OncoBites, we made a cancer research blog and then… forgot to tell our readers what cancer is. And I know, most of you reading are thinking “I know what cancer is!” because you read about it all the time. And maybe, if you’re a…
Cancer – how much of it is preventable?
Morgan McSweeney What percent of cancer cases are due to lifestyle choices or environmental conditions, and are therefore potentially preventable? Take a guess: 10%, 25%, 75%, or 90%? A paper by Anand et. al set out to answer exactly this question nearly ten years ago, pulling data from large-scale epidemiological studies across a large range…
Engineering aggressive breast cancer subtype may allow more treatment choices
Manisit Das Breast cancer may sound like a single disease, but it is not. There are many subtypes of the disease, which guide the course of disease progression and treatment strategy. One of these subtypes, referred to as triple-negative breast cancer (TNBC) is particularly difficult to treat. Recently, researchers at Lund University, Sweden identified a…
From bacteria in your gut to cancer in your skin, everything is connected
Sara Musetti The word “bacteria” is often accompanied by a nose wrinkled in disgust and thoughts of infection and disease. Even though we have as many microbial cells as human cells within each of us—that’s right, we’re 50% bacteria—most people still find bacteria something to avoid. However, recent research into the gut microbiome, the ecosystem…
