Mesenchymal-epithelial interactions involving epiregulin in tuberous sclerosis complex hamartomas.
Patients with tuberous sclerosis complex (TSC) develop hamartomas containing biallelic inactivating mutations in either TSC1 or TSC2, resulting in mammalian target of rapamycin (mTOR) activation. Hamartomas overgrow epithelial and mesenchymal cells in TSC skin. The pathogenetic mechanisms for these changes had not been investigated, and the existence or location of cells with biallelic mutation...
متن کاملLoss of heterozygosity in tuberous sclerosis hamartomas.
We have previously described in tuberous sclerosis (TSC) hamartomas the phenomenon of loss of heterozygosity (LOH) for DNA markers in the region of both the TSC2 gene on chromosome 16p13.3 and the TSC1 gene on 9q34. We now describe the spectrum of LOH in 51 TSC hamartomas from 34 cases of TSC. DNA was extracted from leucocytes or normal paraffin embedded tissue, and from frozen paraffin embedde...
متن کاملIncidence of hepatic hamartomas in tuberous sclerosis.
Hepatic hamartomas were thought to be a rare finding in patients with tuberous sclerosis. The purpose of this study was to assess their incidence in children with tuberous sclerosis and to review the literature. During 1984-90 we examined 51 children by ultrasonography; there were 25 boys and 26 girls. Their age ranged from 3 months to 18 years. Liver hamartomas were seen in 12 (23.5%) of the c...
متن کاملThe tuberous sclerosis complex.
Tuberous sclerosis complex (TSC) is an autosomal dominant disorder that results from mutations in the TSC1 or TSC2 genes and is associated with hamartoma formation in multiple organ systems. The neurological manifestations of TSC are particularly challenging and include infantile spasms, intractable epilepsy, cognitive disabilities, and autism. Progress over the past 15 years has demonstrated t...
متن کاملTuberous sclerosis complex.
Contrast enhanced computed tomography revealed a large well-circumscribed heterogenous retroperitoneal mass measuring 25 × 20 cm arising from the left kidney with predominant fat attenuation. Multiple smaller lesions were seen in the opposite kidney. Features were suggestive of diffuse angiomyolipomatosis of the kidneys. Hypodense lesions were also seen involving the lungslymphangioleiomyomatos...
