Looking forward to using our new Seahorse across a bunch of projects for metabolic studies…just having to re-learn my undergraduate biochemistry though 😉

Great to catch up with my fab friend Tim (from our undergraduate days) who was recently promoted to Prof. in Structural Biology at the University of Birmingham.

6/8 Supporting evidence:
Aggressive cancers often downregulate/mutate DMD.

Less aggressive cancers retain intact DMD.

So, DMD’s role is context-dependent.

4/8 Pathway analysis revealed two contrasting patterns:

High DMD protective → ECM integrity & adhesion preserved.

High DMD harmful → morphogenesis & cellular plasticity promoted.

3/8 Isoform analysis was crucial:

Dp71ab was the dominant transcript and mirrored survival patterns.

Dp40 also appeared consistently.

This suggests isoforms, not just total DMD drive the biology.

2/8 Using TCGA data (33 cancers), we found DMD expression significantly linked to survival in 9 cancers.

But the direction split:

High DMD = ⬆️ survival (breast, lung, pancreas, AML, uveal melanoma)

High DMD = ⬇️ survival (glioma, thymoma, kidney and rectal)

🚨 New in FEBS Open Bio!
During COVID, with labs disrupted, I undertook an MRes apprenticeship in bioinformatics. As a professor, I was suddenly a student again, learning coding to support my group.

Together with @Weekademia, we propose a unified model of DMD in cancer. 🧵👇

6/🧬 RNAseq analysis revealed:

388 genes upregulated (muscle pathways).

30 genes downregulated (ribosome biogenesis, RNA processing).
Suggests DMD’s role extends beyond muscle—it may regulate cancer cell biology.

Cell experiments: Overexpressing Dp71ab disrupted nuclei & slowed proliferation, hinting at tumor-suppressive effects.
March 28, 2025 at 4:32 PM
5/🔍 In tumor tissues:

Dystrophin protein was found in nuclei & cytoplasm.

High nuclear dystrophin = 31-month survival boost (p=0.0497).

4/🦠 HPV status is a known HNSCC prognostic factor, but DMD added nuance:

HPV+ patients with low DMD had worse survival than HPV+ with high DMD.

Suggests DMD could refine risk stratification beyond HPV alone.
March 28, 2025 at 4:32 PM
3/📊 Dp71ab was the star: Patients with high levels had a 42-month survival advantage (p=0.0007). But Dp427m (full-length dystrophin) showed the opposite trend—high expression = worse survival. Context matters!
March 28, 2025 at 4:32 PM
2/🔬 DMD mutations cause muscle disorders, but growing evidence shows it’s involved in cancer. we focused on HNSCC, where high DMD expression correlated with:
-22-month longer median survival (p=0.0083)
-Better progression-free survival (p=0.0237)
-Key player? The Dp71ab isoform.

1/🧵 Our new study in Scientific Reports reveals a surprising link between the Duchenne muscular dystrophy gene (DMD) and head & neck squamous cell carcinoma (HNSCC) survival. High DMD expression = better outcomes! #CancerResearch #HNSCC rdcu.be/efuJZ

Delighted our team won best poster at #ESMORareCancers25 with work spearheaded by former PhD @LSJones4. Work coming out shortly in @SciReports #dmd #hnscc

Looking forward to an exciting few days at #ESMOSarcomaAndRareCancers25
March 20, 2025 at 9:33 AM
Had the pleasure of presenting @LeicResearch head and neck m&m with @LSJones4 on our head and neck cancer work with @profkarena.bsky.social and Leanne's post-doc working @unibirmingham.bsky.social on the biology of #HPV

Hello old friend..

Lovely view over the Nene river this morning from campus
