Este trabajo representa una contribución significativa a la comprensión del mecanismo molecular de acción de un pesticida organoclorado como el Hexaclorobenceno en la carcinogénesis mamaria


Demostramos que el pesticida organoclorado Hexaclorobenceno estimula la migración celular y las vías de señalización c-Src/HER1/STAT5b y HER1/ERK1/2 en la línea de carcinoma mamario humano MDA-MB-231. Observamos que c-Src, HER1 y el Receptor de Hidrocarburos Aromáticos (AhR) están involucrados en la acción del pesticida sobre la migración celular. Este trabajo representa una contribución significativa a la comprensión del mecanismo molecular de acción del HCB en la carcinogénesis mamaria.
