Not Only Engineering Nanomedicines, but Also Modulating the Host: The Gut Microbiome Shapes Chemotherapy Delivery to Tumors

A mouse study shows that short-term alteration of the gut microbiome can reduce the liver’s interception of nanoparticle chemotherapy drugs, prolong their circulation in the blood, and increase tumor accumulation. This “microbiome–bile acid–liver macrophage” pathway offers a new direction for regulating drug delivery.

Shrinking Breast Cancer Into a Petri Dish: Patient-Derived Organoids Reveal Drug-Resistance Vulnerabilities

The research team combined tumor data from the I-SPY2 clinical trial with 44 breast cancer organoids, reproducing some treatment responses and searching for combinations that could overcome drug resistance; the findings remain a preprint supported by laboratory validation, and their use in selecting drugs for individual patients is still some way off.

Taking Blood’s Epigenetic Clues Across Tissues: Machine Learning Charts a Path for Prenatal Variant Interpretation

Using Down syndrome as a proof of concept, a research team converted DNA methylation signatures from postnatal blood into a cross-tissue classifier, with the aim of adding another layer of evidence for interpreting variants of uncertain significance identified by prenatal sequencing; however, hurdles including expansion to other diseases and prospective validation remain before it can become a routine clinical test.
