Transfer of oncogene in colon cancer cells demonstrated

For years, doctors and scientists have known very little about why patients can receive drugs successfully for months, or even years, before developing a drug resistance. New University of Minnesota Medical School research proposes that there is a cellular as well as molecular cause to this phenomenon in colon cancer, with potential application to other

Special fibroblasts help pancreatic cancer cells evade immune detection

Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer-related deaths in the world. Mostly chemoresistant, PDAC so far has no effective treatment. Understanding the connective tissue, called stroma, that surrounds, nurtures, and even protects PDAC tumors, is key to developing effective therapeutics. “PDAC patients are diagnosed really late, so we don’t know they’re

Macrophages’ pathway to nurture PTEN-deficient glioblastoma

A common genetic deficiency empowers glioblastoma to broadcast a molecular message to the wrong type of immune cell, summoning macrophages that protect and nurture the brain tumor instead of attacking it, researchers at The University of Texas MD Anderson Cancer Center report in Cancer Cell. The team’s work in mouse models of glioblastoma that lack

New method for engineering metabolic pathways: Two approaches provide faster way to create complex molecules

Cells are incredibly adept at creating complex molecules, like therapeutics, and can do so much better than many of our best factories. Synthetic biologists look to re-engineer cells to make these molecules for specific needs, including pharmaceuticals and energy applications. But the trial-and-error process is difficult and time-consuming, and often competes with the cell’s other

Most e-cigarette users want to quit, study finds: Findings highlight the need for more emphasis on treatment for e-cigarette cessation

Most people who smoke e-cigarettes want to quit and many have tried to reduce their use, according to Rutgers researchers. The study, published in the journal Nicotine & Tobacco Research, is the first to examine e-cigarette users’ past attempts and current intentions to quit e-cigarettes in a representative sample of adult e-cigarette users in the

New strategy of reprogramming regulatory T cells may improve cancer therapies: Converting immunosuppressive cells into inflammatory cells appears to prime tumors for immune checkpoint blockade

While therapies that harness the power of the immune system against cancer have made remarkable progress against certain types of tumors, they still remain ineffective in most cancer patients. A new study from the Center for Immunology and Inflammatory Diseases (CIID) at Massachusetts General Hospital (MGH) describes a method of reprogramming the regulatory T cells

Cause of sepsis-induced lung injury

A KAIST research team succeeded in visualizing pulmonary microcirculation and circulating cells in vivo with a custom-built 3D intravital lung microscopic imaging system. They found a type of leukocyte called neutrophils aggregate inside the capillaries during sepsis-induced acute lung injury (ALI), leading to disturbances and dead space in blood microcirculation. According to the researchers, this

Image-based computer model reveals finer details of tumor blood flow

Johns Hopkins Medicine researchers say they have developed something akin to a “Google Maps” approach for more accurately computing and visualizing the structural and functional blood vessel changes needed for tumor growth. By pairing high-quality 3D imaging data of tumor specimens from animal models with sophisticated mathematical formulas, the researchers say they now have a

Targeted therapy proves effective against aggressive rare blood cancer: Clinical study treating BPDCN with tagraxofusp led to first FDA approval for the disease

A multi-institutional clinical trial has given good results for a targeted therapy to treat a rare, aggressive blood cancer known as blastic plasmacytoid dendritic-cell neoplasm (BPDCN). Details on the trial, which supported Food and Drug Administration approval of the tagraxofusp therapy in December 2018, have been published in the New England Journal of Medicine. Diagnosed

Mechanism of resistance to BRAF inhibitors in melanoma identified: A conserved stress response mechanism leads to BRAF inhibitor resistance through AP-1 activation

Melanoma is one of the most aggressive types of skin cancer, but recent advances in targeted therapies have improved the prognosis for many patients. Unfortunately, for some patients these positive outcomes are not long lasting, due to the development of drug resistance and tumor recurrence. Moffitt Cancer Center researchers have discovered a mechanism by which

Breakthrough in knowledge of how some sarcomas arise

The origin of certain cancers in the sarcoma group is associated with a hitherto unknown interaction among different proteins. Findings now being presented create the opportunity to test new treatments of these forms of sarcoma. “We now know which mechanisms to shine the spotlight on,” says Pierre Åman, Professor of Tumor Biology at Sahlgrenska Academy,

Radiomics predicts who will benefit from chemotherapy

Using data from computed tomography (CT) images, researchers may be able to predict which lung cancer patients will respond to chemotherapy, according to a new study published in the journal Radiology: Artificial Intelligence. Platinum-based chemotherapy is typically the first-line treatment of advanced-stage non-small cell lung cancer (NSCLC). However, only about one in four patients responds

Coping with cancer: Partners can reframe challenging situations

We’re often told we are responsible for our own happiness. But in challenging situations, a UC Riverside study not only demonstrates the benefits of positive reframing — finding a “silver lining” — but also suggests our partners can be more adept at finding that silver lining than we are. A UCR psychology researcher says the
