A study by Universidad Carlos III de Madrid uncovers how low pH outside cells destabilizes microtubules, affecting the Golgi apparatus and disrupting internal cellular transport. This mechanism is crucial for understanding diseases like cancer and diabetes, where extracellular acidosis is prevalent.
- 01The study identifies a pH-sensitive receptor, β1 integrin, that triggers a signaling cascade leading to microtubule destabilization.
- 02Microtubules are essential for cellular transport, akin to avenues in a city, and their disruption can displace the Golgi apparatus.
- 03Extracellular acidosis is linked to various diseases, including cancer and diabetes, where it alters normal cellular functions.
- 04Advanced techniques like total internal reflection fluorescence microscopy were used to explore microtubule dynamics.
- 05The findings may guide future therapeutic developments to protect cellular systems in pathological conditions.

Research from Universidad Carlos III de Madrid (UC3M) reveals that low pH levels outside cells can destabilize microtubules, crucial for internal cellular transport, and displace the Golgi apparatus, the cell's logistics center. This study highlights the role of extracellular acidosis, common in diseases like cancer and diabetes, in disrupting cellular functions. The research identifies β1 integrin as a pH-sensitive receptor that activates a signaling pathway leading to microtubule destabilization. Using advanced microscopy techniques, the team demonstrated how acidic environments affect microtubule dynamics, likening the disruption to damaged streets in a city. This work not only enhances our understanding of cell biology but also opens avenues for potential therapeutic targets to combat diseases characterized by metabolic imbalances. The study's findings, published in the Journal of the American Chemical Society, underscore the importance of pH in cellular health and disease.
