New Approach Methodologies (NAMs) for drug development are transforming biomedical research by replacing or complementing animal models. More than 90% of experimental compounds fail in clinical trials, underscoring the need for strategies that better capture human biology. Many of these techniques were showcased at the 2026 American Association for Cancer Research (AACR) annual meeting.

The development of glucagon-like peptide 1 receptor (GLP-1R) agonists, such as semaglutide and tirzepatide, has been a game changer in the clinical management of overweight and obesity, but there is interpersonal variability in efficacy of these medications for weight loss, as well as in the incidence of undesired side effects. Investigators from the 23andMe Research Institute have shed some light on how variations in the GLP-1R and GIP receptor (GIPR) genes impact their effectiveness and the occurrence of side effects.

An international team led by Australia’s Walter and Eliza Hall Institute (WEHI) has created the first authoritative atlas for a class of enzymes that regulate almost every cellular process in the human body. The new atlas identifies 672 high-confidence E3 ligases and provides a new reference framework for disease biology and targeted protein degradation research.

South Korean researchers led by Lee In-suk of Yonsei University have reported the most complete oral microbiome catalog to date, with more than 72,000 genomes. Detailed in Cell Host & Microbe on Nov. 12, 2025, the database is expected to serve as a universal platform for academia and enable “precision microbiome medicine” for the industry, Lee told BioWorld.

Researchers at Monash University in Melbourne, Australia, have uncovered the hidden code governing how genetic mutations affect RNA splicing and result in disease. The researchers were able to identify the specific mutations that cause changes in RNA splicing, Sureshkumar Balasubramanian, the lead researcher at Monash University’s School of Biological Sciences, told BioWorld.

Multiple sclerosis (MS) is an immune-mediated inflammatory disease characterized by demyelination and degeneration in the central nervous system.

Cellular atlases and omics studies, such as genomics, transcriptomics and proteomics, have become key tools for identifying the diversity of all the elements that make up the cardiovascular system. These approaches help scientists understand how cells, genes and molecules function and interact in both healthy and diseased conditions, revealing critical points where targeted interventions could not only relieve symptoms but potentially reverse the underlying pathology at its origin.

A large-scale study has revealed the impact of germline variants on proteins in 10 cancer types. Scientists from the National Cancer Institute’s Clinical Proteomic Tumor Analysis Consortium (CPTAC) conducted a precision proteogenomic analysis in a pan-cancer study with data from 1,064 patients, identifying tumor heterogeneity and tumorigenesis associated with heritable genetic alterations.
