Project description:Little is known about how Kiss1 cells in the medial amygdala (MeA) are regulated and what other gene transcripts are produced by MeA Kiss1 neurons. Estradiol upregulates Kiss1 expression in the medial amygdala (MeA), but it remains unknown if estradiol regulates other gene transcripts in MeA Kiss1 cells. The goal of this study is to identify novel gene transcripts produced by MeA Kiss1 cells and to determine how estradiol regulates the expression of these transcripts. We selectively isolated mRNA from Kiss1 cells in the MeA of female mice using Ribotag transgenic mice, immunoprecipitation, and RNA-seq. Over 13,000 gene transcripts produced by MeA Kiss1 cells were identified, but only 45 of these transcripts had expression levels altered by estradiol.
Project description:merMEDEA (MEA) is a component of the Polycomb Repressive complex 2 (PRC2) of Arabidopsis thaliana, and a maternal imprinted gene that functions during central cell, embryo and endosperm development. Seeds that develop from mea mutant egg cells abort regardless of the paternal genotype. With this approach, we aim to uncover putative genes that are downstream of MEA and might cause the seed abortion phenotype. For this, we compare three developmental time point datasets between wild-type and mea mutant: ovary (before fertilization), and seed at 1-2 and 4 days after pollination (DAP).
