GSE68315: Transcriptomic analysis of the mouse mammary gland reveals new insights for the role of serotonin in lactation

Bulk RNA sequencing

Serotonin in the mammary gland is known to regulate processes such as calcium homeostasis, tight junction permeability, and milk protein gene expression. The objective of this study was to discover novel genes, pathways and functions which serotonin modulates during lactation. The rate-limiting enzyme in the synthesis of non-neuronal serotonin is tryptophan-hydroxylase (TPH1). Therefore, we used TPH1 knock-out mice dams (serotonin deficient) and compared them to wild-type dams and also Tph1 deficient dams injected daily with 5-HTP. Mammary gland tissues were collected on day 10 of lactation and then analyzed by RNA sequencing. SOURCE: Francisco Pe├▒agaricano ( - University of Florida
