Research resource: A genome-wide study identifies potential new target genes for POU1F1.

ABSTRACT: The pituitary transcription factor POU1F1 is required for the differentiation of lactotrope, thyrotrope, and somatotrope cells. Its expression is maintained in the adult and is crucial for the expression of prolactin, GH, and TSHβ-subunit. Different studies indicated that POU1F1 could also have other functions in these cells. The identification of new targets of this factor could be useful to obtain a better understanding of these functions. To address this question we combined data obtained from expression microarrays and from chromatin immunoprecipitation (ChIP)-chips. Gene expression microarray assays were used to detect genes that have their expression modified in somatolactotrope GH4C1 cells by the expression of a dominant-negative form of POU1F1, POU1F1(R271W), and led to the identif
