The NAT-RD group, led by Dr Virginia Arechavala-Gomeza at Biobizkaia Health Research Institute, develops nucleic acid-based therapeutics for rare diseases. Our research is particularly focused on neuromuscular disorders, including Duchenne muscular dystrophy (DMD), myotonic dystrophy type I (DM1), and collagen VI-related muscular dystrophies (COL6-RDs). We also collaborate with research teams working on cardiac diseases, paediatric cancers, and other rare conditions where RNA-targeted therapies are under development.






Main Research Lines:
1. Development of Nucleic Acid Therapeutics
We design and evaluate antisense oligonucleotides (ASOs), CRISPR/Cas9 gene editing, and other RNA-based strategies to correct or modulate disease-causing mechanisms at the transcript or genome level. These approaches include exon skipping, splicing modulation, gene correction, and inhibition of toxic RNA species, and are tested in relevant patient-derived cellular models.
2. Disease Modelling and Quantitative Assays
We develop and characterise cellular models using primary patient cells, immortalised lines, iPSC-derived cells, and CRISPR/Cas9-edited models to replicate disease mechanisms in vitro. A key focus of this research line is the development of quantitative and scalable assays—including in-cell and on-cell western-based methods such as myoblots and collablots, droplet digital PCR, and other custom immunodetection approaches—designed to enable robust and reproducible evaluation of therapeutic candidates.
3. Screening and Evaluation of Small Molecules
We carry out small molecule screening to identify compounds that modulate RNA metabolism, improve muscle health, or enhance the efficacy or delivery of nucleic acid therapeutics. These studies use our disease models and validated quantitative readouts to support both discovery and preclinical validation.
4. Open Science and Publishing Integrity
We are strongly committed to transparency and reproducibility in preclinical research. A transversal element of our work is the effort to reduce publication bias, including the dissemination of negative or inconclusive results when methodologically sound, to contribute to a more rigorous and efficient scientific process.

Our team brings together researchers with expertise in molecular biology, pharmacology, bioinformatics, and biotechnology. Through close collaboration with clinicians, academic researchers, industry partners, and patient organisations, we aim to translate our findings into tangible therapeutic advances for people living with rare diseases.
