Papagianni, Aikaterini (Date of defense: 2017-09-14)
During early development of bilaterian animals, specific body structures are formed and body axes are established. The establishment of body axes requires the precise and coordinated function of signalling pathways and ...
El Mouali Benomar, Youssef (Date of defense: 2017-09-15)
The regulation of the expression of virulence genes in Salmonella enterica serovar Typhimurium is an intensively studied feature of Salmonella lifestyle. How Salmonella integrates environmental signals to activate ...
Sureda Gómez, Miquel (Date of defense: 2017-09-15)
La vía Wnt canónica es una vía de señalización muy conservada a lo largo de la evolución de los animales. Esta vía controla múltiples procesos como es la especificación del eje anteroposterior o el destino celular durante ...
