Tuberous Sclerosis (tsc2+/-) Model Eker Rats Reveals Extensive Neuronal Loss with Microglial Invasion and Vascular Remodeling Related to Brain Neoplasia.
Tuberous sclerosis complex (TSC) is an autosomal dominantly inherited neurocutaneous disorder caused by inactivating mutations in TSC1 or TSC2, key regulators of the mechanistic target of rapamycin complex 1 (mTORC1) pathway.
These phenotypes only become apparent when differentiating TSC2+/+ and TSC2-/- cultures in more physiologically relevant conditions of 5 mM glucose suggesting that the careful consideration of culture conditions is vital to ensuring biological relevance and translatability of stem cell models for neurological disorders such as TSC.
In PLAM patients, with and without clinical tuberous sclerosis, mutations in the tuberous sclerosis complex involving the proteins hamartin and tuberin have been found.
CBD has been reported to decrease seizures and inhibit tumour cell progression, therefore we sought to determine the influence of CBD on TSC pathology in zebrafish carrying a nonsense mutation in the tsc2 gene.
Tuberous Sclerosis Complex (TSC) and Lymphangioleiomyomatosis (LAM) are caused by inactivating mutations in TSC1 or TSC2, leading to mTORC1 hyperactivation.
Tuberous sclerosis complex (TSC) is a rare neurodevelopmental disorder resulting from autosomal dominant mutations in the TSC1 or TSC2 genes, leading to a hyperactivated mammalian target of rapamycin (mTOR) pathway, and gray and white matter defects in the brain.
Combined with her clinical presentation, the patient was diagnosed with TSC after molecular analysis revealed she had inherited the TSC2 c.1832G>A (p.R611Q) mutation from her mother.
Finally, phosphorylation defective TSC2 mutants (S932A and S939A single mutants and a S932A/S939A double mutant) failed to upregulate mTORC1 activity in the presence of translation inhibitors, suggesting that activation of mTORC1 by translation inhibitors is mediated by PKC-δ phosphorylation of TSC2 at S932/S939, which inactivates TSC.
Tuberous sclerosis complex (TSC) is a rare autosomal dominant genetic disorder associated with mutations in TSC1 and TSC2 genes, upregulation of mammalian target of rapamycin signaling, and subsequent tumor formation in various organs.
Tuberous sclerosis complex (TSC) is a tumor suppressor syndrome caused by mutations in <i>TSC1</i> or <i>TSC2,</i> encoding hamartin and tuberin, respectively.
A novel de novo splicing mutation c.1444-2A>T in the TSC2 gene causes exon skipping and premature termination in a patient with tuberous sclerosis syndrome.
The secondary aim was to confirm the presence of tuberous sclerosis complex (TSC) through the evaluation of germline mutation in TSC1/TSC2 and assess the outcomes in affected fetuses and newborns.
Through the discovery of the TSC1 and TSC2 genes and the signaling pathways responsible for the pathology of TSC, a new drug target called mechanistic target of rapamycin complex 1 (mTORC1) was discovered.
