Heat shock or transfection with heat shock protein 70 (Hsp70) genes has been shown to protect tumor cell lines against immune mechanisms of cytotoxicity. We have reported previously that heat shock confers resistance to CTL in the rat myeloma cell line Y3 that is Hsp70 defective. Evidence is now presented that Hsp70 is able to prevent the induction of the(More)
We have shown previously that acute heat shock protein (Hsp) 70 induction in a human melanoma cell line containing a doxycycline-inducible Hsp70 expression construct increases lysability of these tumor cells by cytotoxic T lymphocyte (CTL) without interfering with MHC class I expression and antigen presentation. The same parental melanoma cell line has now(More)
The rat is an important model for studying organ graft rejection and susceptibility to certain complex diseases. The MHC, the RT1 complex, plays a decisive role in controlling these traits. We have cloned the telomeric class I region of the RT1 complex, RT1-C/E/M, of the BN inbred rat strain in a contig of overlapping P1-derived artificial chromosome clones(More)
The aim of the present study is to determine the chemical structure and conformation of DNA adducts formed by incubation of the bioactive form of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), N-acetoxy-PhIP, with a single-stranded 11mer oligodeoxyribonucleotide. Using conditions optimized to give the C8-dG-PhIP adduct as the major product,(More)

The complement component C4 is well known for its complex genetics in human and mouse where it is part of a tandemly duplicated module. For the rat, no such information had been available until recently. A C4 gene duplication could be identified also in the rat, but the duplicated module maps approximately 200 kb centromerically from the canonical C4-1(More)
