One hundred and seventy-four rat loci which contain short tandem repeat sequences were extracted from the GenBank or EMBL data bases and used to define primers for amplification by the polymerase chain reaction (PCR) of the microsatellite regions, creating PCR-formatted sequence-tagged microsatellite sites (STMSs). One hundred and thirty-four STMSs for 118(More)
The rat (Rattus norvegicus) is used in a broad field of biomedical research, and numerous animal models for human diseases have been developed. The rat genetic map, however, remains poorly documented. Hedrich (1990) described a rat linkage map consisting of 13 groups, of which only 6 were assigned to chromosomes. Levan and coworkers (1991, 1992) collected(More)
Expression of MAGE genes that encode tumor-rejection antigens recognized by cytotoxic T lymphocytes with major histocompatibility complex class-I antigens was investigated in human osteosarcomas (20 cell lines and eight fresh tumor tissues). MAGE-1, 2, 3, 4, and 6 genes were expressed at the mRNA level in 11 (52.4%), 10 (47.6%), 10 (47.6%) one (4.8%), and(More)
Representational difference analysis (RDA) was applied to isolate chromosomal markers in the rat. Four series of RDA [restriction enzymes, BamHI and HindIII; subtraction of ACI/N (ACI) amplicon from BUF/Nac (BUF) amplicon and vice versa] yielded 131 polymorphic markers; 125 of these markers were mapped to all chromosomes except for chromosome X. This was(More)
The tremor rat is a mutant that exhibits absence-like seizure and spongiform degeneration in the CNS. By positional cloning, a genomic deletion was found within the critical region in which the aspartoacylase gene is located. Accordingly, no aspartoacylase expression was detected in any of the tissues examined, and abnormal accumulation of(More)
The rat zitter (zi) mutation induces hypomyelination and vacuolation in the central nervous system (CNS), which result in early-onset tremor and progressive flaccid paresis. By positional cloning, we found a marked decrease in Attractin (Atrn) mRNA in the brain of the zi/zi rat and identified zi as an 8-bp deletion at a splice donor site of Atrn. Atrn has(More)
A case of acute interstitial nephritis associated with uveitis is presented, An 18-year-old man developed uveitis followed by renal dysfunction. Moderate renal dysfunction (sCr 3.0 mg/dl), and increased levels of urinary beta 2 microglobulin (over 8,000 micrograms/I) were observed. Renal tissue obtained by open renal biopsy revealed severe infiltration of(More)
To correlate rat genetic linkage maps with cytogenetic maps, we localized 25 new cosmid-derived simple sequence length polymorphism (SSLP) markers and 14 existing genetic markers on cytogenetic bands of chromosomes, using fluorescence in situ hybridization (FISH). Next, a total of 58 anchor loci, consisting of the 39 new and 19 previously reported ones,(More)
Almost 10,000 single nucleotide polymorphisms (SNPs) had been identified in the RT1 complex, the major histocompatibility complex of the rat, but less than ∼0.5% have been characterized. In the context of the incomplete characterization of most SNPs, simple sequence length polymorphism (SSLP) marker development is still valuable for understanding the(More)
BACKGROUND Although the rat is extensively used as a laboratory model, the inability to utilize germ line-competent rat embryonic stem (ES) cells has been a major drawback for studies that aim to elucidate gene functions. Recently, zinc-finger nucleases (ZFNs) were successfully used to create genome-specific double-stranded breaks and thereby induce(More)
