Genome-wide maps of chromatin state in LbetaT2 cells or in the pituitary tissues of wild-type and Foxk2 knockout mice.

First, we report a series of ChIP-seq results in LbetaT2 cells. Briefly, we performed ChIP-seq experiments with antibodies specific for Foxk2, Sin3a, Tet1 and Uhrf1 in LbetaT2 cells. We found that a total of 343 different promoters including Nab2 that are co-targeted by Foxk2, Sin3a, Tet1 and Uhrf1. Next, hMeDIP-seq and ChIP-seq experiments with antibodies specific for 5hmC and H3K18ub in the pituitary tissues of wild-type and Foxk2 knockout mice were performed. The results showed that compared to the wild-type mice, knockout of Foxk2 reduced the enrichment of 5hmC and H3K18ub on the Foxk2 target gene.This study revealed a critical switch control of FOXK2 for GnRH pulse frequency-dependent LH production and gave us a new understanding of the role of Foxk2 in chromatin status and gene transcription.
