AI designs a novel E. coli killer

In science, the suffix “phage” means to devour. Thus, the name bacteriophage might conjure images of tiny creatures that “eat” bacteria. While that conception isn’t 100 percent scientifically accurate, bacteriophages are lethal bacteria killers nonetheless, and scientists are excited about engineering phage DNA as a path to new antibiotics.

And so it is that chemical engineer Brian Hie and bioengineering graduate student Samuel King came to study bacteriophage ΦX174 (pronounced “FYE-ex-1-7-4”).

GLP-1 drug linked to heart benefits for high-risk patients

Adding the GLP-1 receptor agonist drug tirzepatide (marketed as Mounjaro) to standard care for patients with type 2 diabetes and heart disease is associated with a lower risk of a major cardiovascular event, such as a heart attack or stroke, finds a study published by The BMJ.

Randomised trials and observational studies have shown non-inferior effects of tirzepatide compared to another GLP-1 receptor agonist, dulaglutide, for major adverse cardiovascular events (MACE) - a combined measure of heart attack, stroke, and death from any cause.

FDA approves daraxonrasib for metastatic pancreatic cancer following landmark clinical trial led by Dana-Farber

The U.S. Food and Drug Administration (FDA) has approved daraxonrasib, an oral multi-selective RAS(ON) inhibitor, for adults with metastatic pancreatic adenocarcinoma who have received at least one prior systemic therapy or are not candidates for multiagent systemic therapy. The approval is based primarily on the results from the pivotal randomized phase 3 RASolute 302 trial comparing daraxonrasib to chemotherapy as second-line therapy for patients with metastatic pancreatic cancer, led by Brian Wolpin, MD, MPH, director of the Hale Family Center for Pancreatic Cancer Research at Dana-Farber Cancer Institute.

Targeting MDA-9 restrains head and neck tumor growth and eliminates therapy resistance

Chemotherapy remains a cornerstone of treatment for head and neck cancers, the seventh-most common cancer type worldwide. However, the disease is often diagnosed at a late stage once it has already spread to other organs, and the majority of patients on active treatment will develop resistance to chemotherapy within a matter of months, underscoring a prominent avenue for designing more effective care strategies.

Engineered human neurons rebuild damaged spinal cord circuits

Spinal cord injuries affect an estimated 15 to 20 million people worldwide, often causing lasting impairments in movement, sensation, and independence. Such injuries can be especially devastating when they occur at the level of the neck, where damaged spinal circuits disrupt signals that control the diaphragm, the main muscle used for breathing.

Despite advances in emergency care and rehabilitation, no approved therapies exist to rebuild the neurons and connections lost after a spinal cord injury.

Scientists unveil more than 600 new tissue models of human cancer

To develop new targeted treatments for cancer, scientists need tissue models that accurately represent the genetic and molecular traits of the cancer they’re studying. An international team led by researchers at MIT’s Koch Institute, the Broad Institute, the Dana-Farber Cancer Institute, the National Cancer Institute, and numerous other partnering institutions has developed nearly 700 new cancer models, derived from patient tumors, which they hope will aid in drug development.

CS18: a new drug that can potentially overcome cancer drug resistance

Researchers at Baylor College of Medicine have developed a drug called CS18 that disrupts the ability of cancer cells to survive therapy. The findings, published in Science Advances, support exploring the possibility of using CS18 to treat human cancer in the future.

“Therapeutic resistance is a main obstacle to achieve effective and durable cancer treatments,” said corresponding author Dr. Weei-Chin Lin, professor of medicine - hematology and oncology and of molecular and cellular biology at Baylor.

First-in-class small molecule inhibitor designed with AI support shows promise against pancreatic cancer in preclinical studies

Mayo Clinic researchers have developed an experimental drug with the help of artificial intelligence (AI) to target the "undruggable" PDZ-domain of GIPC1 protein that helps different types of cancer, including pancreatic cancer, to grow and resist treatment. In laboratory studies, the drug slowed tumor growth, improved survival and enhanced the effects of the chemotherapy drug gemcitabine.

The findings, published in Cell Reports, also demonstrate how AI could help develop a small molecule inhibitor of a target protein that can be less toxic and speed the discovery of new cancer treatments.

Pfizer and Valneva's Lyme disease vaccine candidate Marketing Authorization Application validated by European Medicines Agency

Pfizer Inc. (NYSE: PFE) and Valneva SE (Nasdaq: VALN; Euronext Paris: VLA) announced that the European Medicines Agency (EMA) has validated the Marketing Authorization Application (MAA) for PF-07307405, the companies’ 6-valent outer surface protein A (OspA)-based Lyme disease vaccine candidate and will begin its assessment of the application.

The application is based on encouraging efficacy of more than 70% observed in the Phase 3 VALOR “Vaccine Against Lyme for Outdoor Recreationists” clinical trial (NCT05477524), which investigated whether the vaccine candidate, PF-07307405, prevented Lyme disease cases in individuals aged five years and older.

Staying on diabetes medication is linked to fewer heart attacks and strokes

Type 2 diabetes is associated with an increased risk of heart disease. So many people with type 2 diabetes are prescribed blood sugar-lowering medication to reduce this risk.

However, not everyone takes their medication consistently, and that inconsistency could leave them more exposed. Yet scientists have struggled to pin down how much long-term adherence, meaning how reliably someone sticks to a prescription over the years, actually changes a person's risk of a heart attack or stroke.
