SET à interagir avec les éléments régulateurs (promoteur/enhancer) situés en amont des gènes LHβ
et FSHβ et à réguler les marques épigénétiques des histones présentes dans les promoteurs de ces
gènes. Ces différents résultats permettront de mieux comprendre le rôle de SET dans la régulation par
la GnRH des gènes des hormones gonadotropes.
Techniques mises en œuvre par le stagiaire :
Culture cellulaire (lignée gonadotrope LβT2), transfection (plasmides et siRNAs), immunoprécipitation
de la chromatine (ChIP), activité de promoteurs, fractionnement subcellulaire, qPCR et techniques de
biologie moléculaire
