Tsc2 shapes olfactory bulb granule cell molecular and morphological characteristics

Tuberous Sclerosis Complex (TSC) is a neurodevelopmental disorder caused by mutations that inactivate TSC1 or TSC2. Hamartin and tuberin are encoded by TSC1 and TSC2 which form a GTPase activating protein heteromer that inhibits the Rheb GTPase from activating a growth promoting protein kinase called mammalian target of rapamycin (mTOR). Growths and lesions occur in the ventricular-subventricular zone (V-SVZ), cortex, olfactory tract, and olfactory bulbs (OB) in TSC. Here, nestin­-CRE-ERT2 mice were injected with tamoxifen at postnatal days 2 and 3 and brains harvested at postnatal day 60. OBs were subsequently subjected to RNA sequencing. nestin­-CRE-ERT2 mice were injected with tamoxifen at postnatal days 2 and 3 and brains harvested at postnatal day 60. OBs from three mice per condition were subsequently subjected to RNA sequencing.
