Moreover, striatal protein levels of HO-2, which is not a phase II enzyme, were not altered by either the genotypic alterations or the MPTP treatment.
Particular disease manifestations in the founders and in some of their descendants might be explained by genotypic alterations.
SNP array analysis enables detection of genotypic alterations in the tumors of individual patients and, in principle, identification of new areas with common allelic imbalance that could harbor potential tumor suppressors.
This capability is particularly appealing for diseases with complex genotypic alterations such as cancer.
Meiotic nondisjunction can be induced by external agents, such as heat, radiation, and chemicals, and by internal genotypic alterations, namely, point mutations and chromosomal rearrangements.
Where genotypic changes were observed the PPE38F/R and PPE38IntF/IntR PCRs were again used to differentiate between recombination and gene conversion events (Table 2) No cases of within-cluster genotypic alterations were observed.
A practical demonstration of the role that T. cruzi kDNA-induced mutation and genotypic-phenotypic alterations play in the rejection of target cells in Chagas disease requires a 'clean' parasite-free animal model.
The LkDT- and VkDT-induced genotypic and phenotypic alterations might explain the variability of some clinical manifestations of Chagas disease.
The suggestions that T. cruzi infection contributes to accumulation of LkDTs, and that genotypic and phenotypic alterations would drive subsequent autoimmune destruction of "self" target tissues [3], [20] provided the stimuli for our efforts.
Moreover, due to genotypic and phenotypic alterations, these cells often show different drug responsivity from tumors in vivo [ 3, 11].
