Implication

Observational study reveals discordant TSC2 transcript and tuberin expression in human brain tissue, indicating translational control in neural lesions.

Key Points

Determine the cellular distribution of TSC2 mRNA and its protein product, tuberin, across normal human brain tissues and cerebral lesions from patients with tuberous sclerosis.
Analyzed autopsy and biopsy brain tissue from patients with tuberous sclerosis and unaffected control individuals.
Evaluated mRNA transcript and protein distribution using in situ hybridization and antibody-mediated protein detection across multiple brain regions and lesion types.
High levels of both TSC2 transcript and tuberin were detected in choroid plexus epithelium, ependymal cells, motor neurons, Purkinje cells, and cerebellar external granule cells across controls and cases.
Neocortical, hippocampal, and cerebellar internal granule neurons showed abundant TSC2 transcript but modest or low tuberin protein expression, indicating transcriptional and translational discordance.
In tuberous sclerosis lesions, dysplastic cytomegalic neurons, subependymal hamartomas, and subependymal giant cell astrocytomas demonstrated moderate to high levels of both TSC2 mRNA and tuberin, whereas balloon cells showed faint expression.
