New research from @ucsantacruz.bsky.social Genomics Institute affiliate Shaheen Sikandar shows that pregnancy may “reset” how breast tissue ages, reducing cell changes that are linked to higher breast cancer risk later in life. news.ucsc.edu/2026/01/preg...

Loss of BPTF restores estrogen response and suppresses metastasis of mammary tumors Nature Communications - BPTF is known to regulate chromatin accessibility and self-renewal in mammary epithelial stem cells. Here, the authors discover that BPTF inhibition delays tumor formation,...

MaGNet: A Network-Based Method for Quantitative Analysis of the Mammary Ductal Tree in Developing Female Mice - Journal of Mammary Gland Biology and Neoplasia The mammary gland is a uniquely dynamic organ with a branching architecture that develops entirely after birth in response to hormonal cues. A common approach in mammary gland biology is the evaluation of branching morphogenesis to characterize the role of developmental, physiological and molecular perturbations on branching tissue invasion, growth, and maintenance. Yet, the field still lacks a fully open-sourced, quantitative framework to analyze whole-mount mammary tissue images, as a commonly utilized methodology. Here, we present MaGNet (Mammary Gland Network analysis tool), a method that leverages network theory to characterize key features of ductal branching during mammary gland development. Applying this pipeline to mammary gland images captured at three pubertal timepoints, we achieved reproducible quantification of ductal tree expansion across development. In addition, this network analysis pipeline captures ductal expansion induced by pregnancy hormones. By providing open-source tools to the research community, this method may increase reproducibility and broad applicability across diverse organ systems, model organisms, and developmental stages.

Are you looking for a reliable strategy to quantify the architecture of mammary tissue using whole mount images?? Well, maybe you should check MaGNet, our new computational based and user friendly approach (and you probably can adapt it to other organs as well). link.springer.com/article/10.1...

'The polio virus is still circulating worldwide. In 2022, an unvaccinated man in Rockland County, N.Y., was paralyzed by polio. Earlier this year, the virus paralyzed a child in Gaza, the first case in the region in 25 years, which prompted a mass vaccination campaign against polio.'
