Lucía Mayo Sanz’s Master’s Thesis: Unveiling the Diet-Brain Connection in Neurodegenerative Diseases

At Scorrochano Lab, we are celebrating a truly inspiring academic and scientific milestone! With a triumphant smile that speaks volumes, our talented colleague Lucía Mayo Sanz has successfully defended her Master’s Thesis in Neuroscience at the Universidad Complutense de Madrid (UCM). Having earned her degree in Biochemistry from the same university, Lucía has culminated a groundbreaking research project that tackles one of modern biomedicine’s most promising frontiers: exploring how targeted dietary interventions could help counteract progressive neurodegenerative disorders.

The Heart of the Research: FUS, Nutrition, and the Central Nervous System

At the core of Lucía’s thesis is the FUS (Fused in Sarcoma) protein. FUS is an indispensable RNA-binding protein within our central nervous system, playing vital roles in gene regulation, DNA damage repair, and the structural preservation of dendritic spines and synapses. Synapses act as the biological wiring that allows neurons to communicate, enabling cognition, memory, and motor execution.

When mutations such as FusΔ14 occur, this vital functionality is severely disrupted. Pathological FUS mislocalizes from the nucleus into toxic cytoplasmic aggregates, triggering severe neurodegenerative phenotypes characterized by:
– ALS (Amyotrophic Lateral Sclerosis): Rapid degeneration of upper and lower motor neurons, causing loss of voluntary muscle control.
– FTD (Frontotemporal Dementia): Profound cortical atrophy localized in the frontal and temporal lobes, causing behavioral, emotional, and language impairments.

This is precisely where Lucía’s innovative hypothesis comes into play: Could dietary interventions provide a protective neuro-metabolic shield? Utilizing a specialized murine model reproducing the human FusΔ14 mutation, Lucía analyzed how targeted nutritional regimens preserve synaptic density, prevent synaptic loss, and reverse early behavioral decline.

Why This Milestone Matters: Non-Pharmacological Windows of Hope

Lucía’s findings provide profound implications for translational biomedicine:
– Complementary Non-Pharmacological Strategies: Nutrition emerges not merely as supportive care, but as a potent biological tool capable of modulating cellular metabolism alongside targeted pharmaceuticals.
– Cellular Mechanisms Decoded: Shedding new light on the downstream metabolic pathways triggered by cytoplasmic FUS accumulation.
– Patient Quality of Life: Paving the way toward feasible dietary protocols designed to slow functional deterioration in neurodegenerative conditions.

Life in the Lab and the Next Generation of Scientists

At Scorrochano Lab, Lucía’s success embodies the vibrant young talent driving our research forward. Master’s theses represent much more than an academic prerequisite; they are the fertile ground where critical thinking, intellectual curiosity, and rigorous experimental expertise take root. We could not be prouder of Lucía’s passion, dedication, and contagious enthusiasm!
