Bacteria naturally present in the human intestine, known as the gut microbiota, can transform cholesterol-derived bile acids into powerful metabolites that strengthen anti-cancer immunity by blocking androgen signaling, according to a preclinical study led by Weill Cornell Medicine investigators. The study was published on April 15 in Cell.

A new, error-corrected method for detecting cancer from blood samples is much more sensitive and accurate than prior methods and may be useful for monitoring disease status in patients following treatment, according to a study by Weill Cornell Medicine and New York Genome Center investigators. The method, based on whole-genome sequencing of DNA, also represents an important step toward the goal of routine blood test-based screening for early cancer detection.

Weill Cornell Medicine’s Celebration of Diversity honored leaders who go beyond their official roles, dedicating time, energy and empathy to build inclusive environments. The ceremony, part of the institution’s seventh annual Diversity Week, was held April 7 in Griffis Faculty Club.

Linoleic acid, an omega-6 fatty acid found in seed oils such as soybean and safflower oil, and animal products including pork and eggs, specifically enhances the growth of the hard-to-treat “triple negative” breast cancer subtype, according to a preclinical study led by Weill Cornell Medicine investigators. The discovery could lead to new dietary and pharmaceutical strategies against breast and other cancers.

Leveraging the power of AI and machine learning technologies, researchers at Weill Cornell Medicine developed a more effective model for predicting how patients with muscle-invasive bladder cancer will respond to chemotherapy. The model harnesses whole-slide tumor imaging and gene expression analyses in a way that outperforms previous models using a single data type.

Weill Cornell Medicine researchers found that restricting telehealth prescriptions for opioid use disorder could keep thousands from accessing buprenorphine, a medication that helps people recover from addiction.

A person’s “bioenergetic age”—or how youthfully their cells generate energy—might be a key indicator of whether they’re at risk of developing Alzheimer’s disease, new research from Weill Cornell Medicine shows. The study, published Feb. 24 in Nature Communications, suggests healthy living can turn back the bioenergetic clock for some people, helping them fend off Alzheimer’s as effectively as a new drug called lecanemab.

A new Weill Cornell Medicine and Oregon Health & Science University co-authored study provides critical insight for the development of a vaccine that can more effectively block the spread of cytomegalovirus, or CMV, across the placenta to babies before they are born.

A single molecular switch is essential for blood stem cells to enter an activated, regenerative state in which they produce new blood cells, according to a preclinical study led by Weill Cornell Medicine investigators. The discovery could lead to more effective bone marrow transplants and gene therapies.
