Abstract
Los genes Ras (H-Ras, K-Ras y N-Ras) codifican las proteínas RAS con funciones fundamentales en la regulación de la supervivencia, diferenciación, crecimiento y apoptosis celular. Aparte de sus propiedades oncogénicas, se sabe poco sobre el contexto y las funciones patofisiológicas dependientes de las células de las proteínas RAS. En particular, N-Ras participa de manera crítica en la función de las células inmunes. La fibrosis hepática se desarrolla en respuesta a citocinas inflamatorias, interacciones celulares con células inmunes y señales morfogénicas. En el presente trabajo, planteamos la hipótesis de que N-Ras juega un papel fundamental en la fisiopatología de la fibrosis hepática...
