Effect of Maternal Separation on DOI-induced transcriptome

While several molecular mechanisms have been hypothesized to mediate the long lasting effects of MS, the serotonin 2a receptor is an attractive candidate, given its role in regulating anxiety-like behavior. So we set out to ask if Maternal Separation alters the 5HT2a responses. In order to assay if MS alters the transcriptional targets of the 5Ht2a receptor, we use a drug that stimulates the 5Ht2a receptor, DOI. The experiment involves injecting both control and MS animals with DOI and looking at the transcriptome induced by DOI under control and MS conditions. This would help understand how the adverse early life experience MS, alters the transcriptional response of an adult rat to stimulation at the 5HT2a receptor, which is physiologically seen in conditions of stress.
