Laura Corso’s Research Focus at the Walter and Eliza Hall Institute

Laura Corso’s Research Focus at the Walter and Eliza Hall Institute

• Transcriptional control: Mapping how transcription factors bind to DNA to switch genes on or off.
• Epigenetic remodeling: Studying histone modifications and DNA methylation that fine‑tune gene expression.
• Non‑coding RNA networks: Uncovering micro‑RNA and long non‑coding RNA (lncRNA) circuits that regulate developmental pathways.
• CRISPR‑based functional screens: Using pooled CRISPR libraries to identify regulatory elements essential for cell fate decisions.

Key Discoveries in Gene Regulation

1. Enhancer‑promoter looping in immune cells – Demonstrated that specific enhancer loops drive rapid cytokine gene activation during infection, providing a mechanistic link to auto‑immune disease susceptibility.
2. Chromatin‑accessibility atlas for hematopoietic stem cells – Generated the first high‑resolution ATAC‑seq map of stem‑cell niches, revealing novel regulatory motifs that predict lineage commitment.
3. lncRNA‑mediated silencing of oncogenes – Identified a lncRNA that recruits the Polycomb repressive complex to silence MYC in early‑stage leukemia, opening avenues for epigenetic therapy.

Cutting‑Edge Methodologies Employed

• Single‑cell RNA‑seq (scRNA‑seq) + multi‑omics integration – Simultaneously captures transcriptome, epigenome, and protein markers in thousands of individual cells.
• CUT&RUN & CUT&Tag – High‑specificity chromatin profiling that reduces background noise compared with conventional ChIP‑seq.
• CRISPRi/a pooled screens – Represses or activates thousands of regulatory elements in parallel to pinpoint functional DNA regions.
• Machine‑learning pipelines – applies deep‑learning models (e.g., transformer‑based architectures) to predict enhancer activity from genomic sequence alone.

Translational Impact on Precision Medicine

• biomarker discovery: Regulatory signatures identified by Corso’s team are being validated as predictive biomarkers for treatment response in acute myeloid leukemia (AML).
• Therapeutic target validation: CRISPR‑based loss‑of‑function screens have highlighted 12 “druggable” transcription factors that modulate chemotherapy resistance.
• Gene‑editing safety: By mapping off‑target chromatin effects, the research informs safer CRISPR therapeutic designs for inherited blood disorders.

Major Collaborations and Funding Sources

Partner Institution	Project Focus	Funding Agency	Grant Amount (AU$)
university of Melbourne – Department of Bioinformatics	Integrated multi‑omics pipeline	Australian Research Council (ARC)	2.5 M
Monash Health Cancer Center	lncRNA therapeutic development	National Health and Medical Research Council (NHMRC)	1.8 M
Broad Institute (USA)	Cross‑species enhancer conservation analysis	Wellcome Trust	1.2 M

Benefits for the Broader Scientific Community

• Open‑access datasets: All ATAC‑seq and scRNA‑seq data are deposited in GEO (accession numbers GSEXXXXX‑GSEXXXXX) and linked to interactive genome browsers.
• Standardised protocols: Published step‑by‑step guides for CUT&Tag in primary immune cells have reduced assay setup time by 30 %.
• Training and mentorship: Corso’s lab runs quarterly workshops on CRISPR screen design, fostering skill development for early‑career researchers.

Practical Tips for Researchers Implementing Similar Gene‑Regulation Studies

1. start with high‑quality nuclei isolation – Gentle lysis preserves chromatin integrity for downstream CUT&RUN.
2. pilot a small CRISPR library – Verify guide RNA efficiency in bulk before scaling to genome‑wide screens.
3. Integrate metadata early – record cell‐type annotations, batch information, and sequencing depth to streamline multi‑omics integration.
4. Leverage existing bio‑informatic tools – Use platforms like Seurat v5 for scRNA‑seq clustering and ArchR for joint ATAC‑seq analysis.
5. Validate computational predictions experimentally – Follow up machine‑learning enhancer predictions with luciferase reporter assays.

Real‑World Example: Enhancer Targeting in Chronic Myeloid Leukemia

• Background: Patients with chronic myeloid leukemia (CML) often develop resistance to tyrosine‑kinase inhibitors (TKIs).
• Corso’s contribution: Identified a distal enhancer that up‑regulates the drug‑metabolism gene ABCB1 in TKI‑resistant cells.
• Outcome: CRISPR interference (CRISPRi) against this enhancer restored TKI sensitivity in vitro, providing a proof‑of‑concept for enhancer‑targeted therapy.

Future Directions in Gene‑Regulation Research at WEHI

• Spatial transcriptomics: Mapping gene‑regulatory networks in tissue sections to capture microenvironmental cues.
• Synthetic regulatory circuits: Engineering programmable enhancers that can be switched on/off with small molecules.
• Patient‑derived organoids: Applying CRISPR screens directly to organoid models to predict individual therapeutic responses.
