O complex de Golgi ao volante de uma célula tumoral

A maioria das funções atribuídas ao Golgi está fortemente associada a eventos celulares centrais para a iniciação e progressão do cancro. No entanto, ainda não compreendemos se e como este enigmático organelo controla o “volante” de uma célula tumoral e de que forma contribui para o seu destino. Este artigo publicado pelo nosso grupo do CBIOS, destaca os mecanismos moleculares e proteínas do Golgi que influenciam o fenótipo de uma célula tumoral, e consequentemente o seu potencial como alvo terapêutico.

Abstract:

Growing evidence connects many of the Golgi known functions with cellular events related to cancer initiation and progression, including regulation of cell survival/death, proliferation, motility, metabolism and immune evasion. However, a broad and integrated understanding of the impact of the Golgi on cancer cell phenotype has not yet been achieved. Multiple cellular events involving the Golgi are associated with protein and lipid modification and trafficking. However, less explored aspects of this enigmatic organelle also contribute to cell fate decision-making by impacting signal transduction, redox and ion homeostasis. This article focuses on the molecular mechanisms and Golgi proteins underlying the impact of the Golgi on cancer cell phenotype. Special emphasis is given to emerging knowledge on redox and ion homeostasis. Current and potential cancer progression therapeutic strategies associated with this organelle will also be addressed.
