siRNA targeting 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase (ATIC)
Efficient sequence specific gene silencing is possible through the use of siRNA technology. By selecting particular siRNAs by rational design, one can maximize the generation of an effective gene silencing reagent, as well as methods for silencing genes. Methods, compositions, and kits generated through rational design of siRNAs are disclosed including those directed to ATIC.

ID NOs. 438-593.
2 . An siRNA comprising a sense region and an antisense region, wherein said sense region and said antisense region together form a duplex region and said sense region and said antisense region are each 18-30 nucleotides in length, and said antisense region comprises a sequence that is 100% complementary to a contiguous stretch of at least 18 bases of a sequence selected from the group consisting of SEQ. ID NOs. 438-593.
