December 31, 2021. Two papers published in 1 week
What an end to 2021, two of our manuscripts were accepted for publication the last week of the year. One manuscript is a review summarizing our current understanding of the role of circadian rhythms in the neuronal circuit regulating the LH surge. The second paper is a research paper in collaboration with UC San Diego, where we identify the transcription factor SIX3 in post-proliferative neurons as required for the correct function of the growth axis: Deletion of Six3 in post-proliferative neurons produces weakened SCN circadian output, improved metabolic function, and dwarfism in male mice.
November 15, 2021. Welcome to our new undergraduate volunteer Jennie Soule!
Jennie will be working with Brooke on her project focused on increasing our understanding of the neuronal circuit responding to light modulating mood and behavior.

November 9, 2019 Paper published in Molecular Neurobiology
We here identify Vax1 as a transcription factor required for SCN development. In addition we show that one of the two Gnrh-cre alleles used targets the SCN causing impaired SCN output in both Vax1 and Six6 conditional knock-out mice. This paper is a reminder to properly understand the potential impact of ectopic cre-allele expression in the obtained results.
