While AI Could Be the Game Changer in Predicting Health Outcomes It Should Not Be the Only Method

University of Maryland School of Medicine — Tue, 15 Apr 2025 19:55:58 EST

With the advent of artificial intelligence (AI), predictive medicine is becoming an important part of healthcare, especially in cancer treatment. Predictive medicine uses algorithms and data to help doctors understand how a cancer might continue to grow or react to specific drugs--making it easier to target precision treatment for individual patients. Now, with the two commentaries just out, researchers at the Institute for Genome Sciences at the University of Maryland School of Medicine set a foundational approach to generating, analyzing, and ethically sharing data to benefit both patients and science.

Study Sheds Light on How Inherited Cancer Mutations Drive Tumor Growth

Washington University in St. Louis — Mon, 14 Apr 2025 11:00:00 EST

Most cancer genome studies have focused on mutations in the tumor itself and how such gene variants allow a tumor to grow unchecked. A new study, led by researchers at Washington University School of Medicine in St. Louis, takes a deep dive into inherited cancer mutations measured in a healthy blood sample and reports how those mutations might take a toll on the body's cells starting at birth, perhaps predisposing a person to develop cancers at various stages of life.

Advanced Imaging Reveals Mechanisms That Cause Autoimmune Disease

University of California San Diego — Wed, 09 Apr 2025 20:50:03 EST

Those who suffer myasthenia gravis experience muscle weakness that can affect the muscles we use to blink, smile and move our bodies. Researchers at UC San Diego's School of Biological Sciences used a cutting-edge imaging technique to uncover new details about the mechanisms underlying the disease.

New Method Identifies Protein That May Govern Cancer Cell Movement and Metastasis

UT Southwestern Medical Center — Wed, 09 Apr 2025 20:40:34 EST

Using a novel method that gives a readout of which proteins are in specific locations within cells, UT Southwestern Medical Center researchers have identified a protein that plays a key role in cell adhesion and movement. Their findings, published in Cell Reports, could help researchers better understand diverse phenomena such as cancer metastasis and cell differentiation.

How A Small Number of Mutations Can Fuel Outbreaks of Western Equine Encephalitis Virus

Harvard Medical School — Fri, 04 Apr 2025 11:00:00 EST

New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn a deadly pathogen into a harmless bug or supercharge a relatively benign virus, influencing its ability to infect humans and cause dangerous outbreaks.

Virus Infects Cells with a Protective Cloaking Mechanism

University of California San Diego — Thu, 03 Apr 2025 20:40:06 EST

Viruses known as "jumbo phage" are a new hope against the rising antibacterial infection crisis. Researchers have discovered how jumbo phage are able to infect bacteria so efficiently. They found a compartment that protects and hides valuable DNA material from the bacteria's immune defense system.

Researchers Find Intestinal Immune Cell Prevents Food Allergies

Washington University in St. Louis — Thu, 03 Apr 2025 20:10:42 EST

Researchers at WashU Medicine found that a small population of immune cells in the mouse intestine prevents allergic responses to food, suggesting that targeting such cells therapeutically could potentially lead to a new treatment for allergies.

Delicate Balancing Act Determines How Many Genome Gateways Form in Cells

Sanford Burnham Prebys — Mon, 31 Mar 2025 11:00:00 EST

As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to lock it down like Fort Knox. Instead, large groupings of more than 1,000 individual protein molecules called nuclear pore complexes (NPCs) pepper the dividing membrane, serving as gateways for materials and messages entering and exiting the nucleus.

Personalized App Reduces Cancer-Related Fatigue

Michigan Medicine - University of Michigan — Thu, 27 Mar 2025 09:10:00 EST

U-M researchers, in collaboration with Arcascope, have developed and tested a personalized app that tracks a user's circadian rhythm and makes behavioral recommendations to reduce daily fatigue.

Why Brain Metastases of Breast Cancer Resist a Promising Candidate Therapy

Ludwig Cancer Research — Mon, 24 Mar 2025 18:10:15 EST

A Ludwig Cancer Research study has identified a key barrier to the efficacy of a promising combination of radiotherapy and immunotherapy for the treatment of brain metastases arising from breast cancer--and in doing so uncovered approaches to overcoming that resistance.

Study Identifies Gut Sensor That Propels Intestines To Move

Harvard Medical School — Mon, 24 Mar 2025 11:00:00 EST

Research in mice identifies protein responsible for regulating gut movement in response to pressure, exercise, and inflammation. The findings can inform precision-targeted treatments for intestinal inflammation and disorders of gut motility. The results add to a growing body of research showing the nervous and immune systems interact in various organs, including the brain, lungs, and skin.

New Study Sheds Light on How Bacteria 'Vaccinate' Themselves with Genetic Material from Dormant Viruses

Johns Hopkins Medicine — Fri, 21 Mar 2025 17:45:44 EST

Johns Hopkins Medicine scientists say they have shed new light on how bacteria protect themselves from certain phage invaders -- by seizing genetic material from weakened, dormant phages and using it to "vaccinate" themselves to elicit an immune response.

Researchers at WashU Medicine boosted lymphatic vessel integrity in old mice and found improvements in their memory compared with old mice without rejuvenated lymphatic vessels.

New Drug Therapy Combination Shows Promise for Advanced Melanoma Patients

Huntsman Cancer Institute at the University of Utah — Fri, 21 Mar 2025 10:25:45 EST

A novel oral combination drug therapy evaluated at Huntsman Cancer Institute could treat and prevent melanoma spreading to the brain. Brain metastasis is the main cause of death from melanoma.

Researchers Find Missing Link in Autoimmune Disorder

Washington University in St. Louis — Tue, 18 Mar 2025 20:55:25 EST
