Sensitization of TNFα and Agonistic FAS/CD95 Antibody-Induced Apoptosis by INFγ on Neuroblastoma Cells
Ho Il Bang, Jong Duck Kim, Du Young Choi
Clin Exp Pediatr. 2003;46(7):702-709.   Published online July 15, 2003
Purpose : IFNγ sentitizes many tumor cells to TNFα and FASL-mediated apoptosis by enhancing the expression of TNF or FAS/CD95 receptor and modulating the activation of caspase and Bcl-2 family.

Clin Exp Pediatr. 2003;46(6):615-619.   Published online June 15, 2003
Cystinosis, an autosomal recessively inherited lysosomal storage disease, results from impaired transport of the amino acid cystine out of cellular lysosomes. The consequent accumulation and crystallization of cystine destroys tissues, causing growth retardation, Fanconi syndrome, renal failure, eye problems, and endocrinopathies. The gene for cystinosis, CTNS, was mapped to chromosome 17p13. The diagnosis of cystinosis was made by measuring the...
