TL;DR

A lineage-resolved monolayer culture system is established that enables propagation of primary human mammary epithelial populations while preserving lineage identity across passages and provides a functional framework for determining critical events in the expansion of genomically altered mammary epithelial cells in the high-risk breast.

Longitudinal single cell RNA-sequencing of Pik3caH1047R-driven mammary tumorigenesis reveals coordinated transformation of epithelial and fibroblast transcriptional states

Breast cancer is a heterogeneous disease in which a single oncogenic driver can give rise to divergent tumor phenotypes. How oncogenic mutations generate epithelial state plasticity and coordinately remodel the surrounding tissue remains incompletely understood. Here, we applied longitudinal single cell RNA-sequencing...

Loss of Sox10 prevents tumor initiation in vivo and induces luminal-to-basal reprogramming in Neu+ tumor cells.

It is demonstrated that Sox10 is required for a permissive luminal cell state for Neu-driven tumor initiation and that it is critical for cancer stem cell activity and the establishment of metastases.

Single‐Cell Dissection of Therapy‐Induced Remodeling Uncovers a Fibroblast‐Driven Immunosuppressive Niche and Targetable Vulnerabilities in Lethal Prostate Cancer

These findings defined the DPT+‐complement‐macrophage axis as an actionable vulnerability and position TSPAN1 and NRXN1 as therapeutic entry points to disrupt ADT‐driven tumor ecosystem remodeling in prostate cancer.

Mouse genetic mosaic model for basal-like breast cancer reveals disruption of basal-myoepithelial architecture at premalignancy

In early cancer evolution, mutant cells must escape tissue-architectural constraints before progressing to malignancy. In the case of invasive breast cancers, loss of integrity of the wildtype basal-myoepithelial layer that wraps around premalignant luminal cells precedes the formation of an invasive tumor mass. The sp...

Developmental and MAPK-responsive transcription factors regulate distinct malignant cell states and associated genetic dependencies in pancreatic cancer

The authors apply ARACNe and metaVIPER to published scRNA-seq datasets to characterize pancreatic cancer subtypes, identifying six distinct cell states as well as their mechanistic determinants.

Evolutionarily conserved epigenetic regulation of transcriptional cell states during vertebrate pancreatic tumorigenesis.

These findings suggest a highly conserved role for HDAC9 and class IIA HDACs in vertebrate pancreatic tumorigenesis and may lead to new strategies for reactivating (normal acinar/epithelial) differentiation programs to intercept and treat PDAC.
