Oncogenic and tumor-suppressive forces converge on a progenitor-orchestrated niche to shape early tumorigenesis
The transition from benign to malignant growth is a pivotal yet poorly understood step in cancer progression that marks the shift from a pathologically inert condition to a clinically lethal disease. ...

🧪 New paper alert!

In new work led by Adele Mossa out now in @natcomms.nature.com, we find that the #autism risk gene #DDX3X is a critical regulator of sexual dimorphisms in neuronal neurodevelopment 🧬 🧠

✨So happy to see part of my PhD work with @lippilab.bsky.social out today in @cp-neuron.bsky.social! ✨

We developed new tools to study microRNA-target networks with greater spatial and temporal resolution and found neuronal subtype- and developmental stage-specific roles:
MicroRNA mechanisms instructing Purkinje cell specification
Zolboot et al. introduce DD-T6B and SAP-seq, methods for investigating microRNA function with enhanced spatiotemporal resolution, and identify Purkinje cell-specific microRNAs and targets instructing ...

our work on the molecular differences between transcription factor isoforms is out now in Molecular Cell!

key point: 2/3rds of TF isos differ in properties like DNA binding & transcriptional activity

many are "negative regulators" & misexpressed in cancer
