Sirena1: The most abundant lncRNA in mouse oocytes brings together post-transcriptional regulations and mitochondrial distribution (mouse dev_stages)

Long non-coding RNAs (lncRNAs) are a large group of rapidly evolving non-coding RNAs. Tens of thousands of lncRNAs were identified but function has been assigned to relatively few. LncRNAs expressed in mouse oocytes have been annotated but their contribution to oocyte development and early development remains unknown. Here, we report evolutionary history and functional analysis of Sirena1, maternal lncRNA that is the most expressed maternal lncRNA and 10th most abundant Pol II transcript in mouse oocytes. Overall design: Bulk RNA-seq of 13 mouse developmental stages samples: - GV oocyte: 3x WT and 3x Sirena1 KO - MII egg: 3x WT and 4x Sirena1 KO
