Abstract
The genotype of the fibroblast growth factor receptor 4 (FGFR4) gene and TP53 mutation have been reported as prognostic factors for cancers of the head and neck, bladder, breast and colon. To determine whether they are applicable for oral squamous cell carcinoma (OSCC), we investigated these two genes in OSCC samples from 150 patients who had undergone radical surgery and in 100 cancer-free individuals. In OSCC, the FGFR4 Gly388Arg polymorphism and the presence or absence of mutation in TP53 did not show a significant association with the clinicopathological features of the tumors at surgery. However, the FGFR4 Arg388 allele, as well as mutations in TP53, was found to be closely associated with poor prognosis. Moreover, these two parameters synergistically affected the survival of OSCC patients. During 60 months of observation after radical surgery, a majority of patients with homozygous Arg388 FGFR4 plus mutated TP53 died of cancer, whereas >90% patients carrying homozygous Gly388 FGFR4 plus wild-type TP53 survived. Therefore, the FGFR4 Gly388Arg polymorphism and TP53 mutations, as well as their combinations, are excellent predictors of the prognosis for OSCC patients.

Abstract
We previously reported that susceptibility to 4-nitroquinoline 1-oxide (4NQO)-induced tongue cancer in Dark-Agouti (DA) and Wistar/Furth (WF) rats was determined by a number of quantitative trait loci. In this article, we further scrutinized one of the quantitative trait loci at a suggestive level on rat chromosome 5. Analyzing a DNA panel of 130 (DAxWF) F2 rats treated with 4NQO showed a quantitative trait loci, containing p15INK4B and p16INK4A. To study the possible relevance of these genes in the development of tongue cancer, we examined 45 4NQO-induced tongue cancers in 100 (DAxWF) F1 rats for loss of heterozygosity. The incidence of loss of heterozygosity at p15INK4B and p16INK4A genes in large advanced tongue cancers was 37.8% and 40.0%, respectively, and the WF allele was selectively lost. Accumulation of loss of heterozygosity and methylation of the promoter regions in the tumour suppressor genes in advanced tumours suggests that they may play a role in tongue cancer progression.

Abstract
Increasing exposure to environmental endocrine disruptor, xeno-estrogen, is a serious hazard to male reproductive activity. To explore possible genetic control in susceptibility to xeno-estrogen, the weight reduction of testes induced by the continuous administration of a synthetic estrogen, diethylstilbesterol, were investigated by quantitative trait analysis in LEXF and FXLE recombinant inbred strain rats, consisting of 21 independent strains, 9 of their substrains, parental F344/Stm and LE/Stm strains, and (F344 x LE)F1. For the weight of testes, one highly significant quantitative trait locus (QTL) and one significant QTL were mapped on chromosomes 7 and 1, respectively. The QTL on chromosome 7 is closely associated with c-myc. Pituitary weight and serum prolactin were also variable among recombinant inbred strains, but no QTL was detected for them in this study.

Abstract
We previously reported that Dark-Agouti (DA) rats are highly susceptible to 4-nitroquinoline 1-oxide (4NQO)-induced tongue cancer (TC), whereas Wistar/Furth (WF) rats are barely susceptible. Linkage analysis of reciprocal (DAxWF)F2 rats demonstrated five quantitative trait loci, Tongue squamous cell carcinoma 1-5 (Tscc1-5) determining the size and number of the TCs. The major susceptibility locus Tscc1 is mapped on rat chromosome 19. In the present study, we used a marker-assisted speed congenic procedure to construct WF.DA-Tscc1 (WF-T1D) rats, i.e. WF rats carrying a DA-derived Tscc1 chromosomal segment, and evaluated the effect of a single Tscc1 on 4NQO-induced tongue carcinogenesis. In WF-T1D rats, the incidence, number and size of 4NQO-induced TCs were significantly higher than those in WF rats, indicating that the introgressed segment contains one of the susceptibility loci for 4NQO-induced TCs from DA rats. Detection of a single nucleotide polymorphism in NQO1, one of the Tscc1 candidate genes, enabled us to map NQO1 in the Tscc1 segment between D19Wox8 and D19Wox7 on chromosome 19. Possible relevance of NQO1 polymorphism to TC susceptibility is discussed.

Abstract
OBJECTIVE This study aims to elucidate the genetic basis of predisposition to 4-nitroquinoline 1-oxide (4NQO)-induced tongue cancers (TCs). MATERIALS AND METHODS We have reported that inbred Dark-Agouti (DA) strain rats were highly susceptible to 4NQO-induced TCs, whereas Wistar/Furth (WF) rats were resistant to tongue squamous cell carcinomas induced by oral administration of 4NQO. Using size and number of the tumours as quantitative parameters, responsible host loci were analysed by an interval mapping of F2 intercross of DA and WF given carcinogenic regimen. Also, loss of heterozygosity (LOH) at these loci was analysed in tongue cancers in (DA x WF) F1. RESULTS We identified and mapped 5 significant quantitative trait loci (QTL), the Tongue squamous cell carcinoma 1-5 (Tscc1-5), and several other suggestive QTL that determine susceptibility to 4NQO-induced TC. Study of TCs induced in (DA x WF)F1 rats revealed a high frequency of LOH in the chromosomal regions of Tscc2, 3, and 4 and also of suggestive QTL on chromosomes 5 and 6. The fact that LOH was found only in larger TCs indicates that LOH occurred in the process of tumour progression. In most LOH, the allele of the resistant WF strain was lost, suggesting that these loci may encode tumour suppressor genes. In larger TCs, in addition to LOH, point mutations and the methylation of possible candidate genes were accumulated. CONCLUSION These observations indicate that the 4NQO-induced TC in the rat is a multifactorial disease of a polygenic trait. This model will be useful to understand the complicated genetic basis of predisposition to oral cancers.

Abstract
The present paper evaluates the inclusion of a standard strain or outbred stock in multi-strain behavioral phenotyping protocols to perform the same role as the external standard in biochemical assay procedures. As potential standards, the F344 inbred strain and an outbred stock of Long Evans were tested with three other inbred strains. To evaluate the influence of rearing conditions on phenotype stability, one group of F344s was born at the University of Tsukuba, another, bred elsewhere and delivered to Tsukuba at 4 weeks of age. All animals were tested in open-field (OF), runway emergence (RE) and digging tests as adults. The results showed no influence of breeding or transportation history on OF and RE behavior of the two F344 groups, while there was evidence that digging behavior may be affected by the different rearing experience. The inclusion of a 'standard strain or stock' in phenotyping protocols involving multiple inbred strains or lines of rats, mice and flies has obvious advantages by providing a reference point for inter-laboratory comparisons. The properties of inbred strains and outbred stocks favorable to their use as standards are discussed.

Abstract
Activator protein-1 (AP-1) is a transcription factor activated in many tumors. Using 4-nitroquinoline 1-oxide (4NQO)-induced rat tongue cancers (TC), the present study investigated the expression levels of genes that encode the components of AP-1, the jun gene family (c-jun, junB and junD) and the fos gene family (c-fos, fra-1, fra-2 and fosB). Expression levels of junB and c-fos mRNAs in TC were significantly elevated compared with those in epithelial tissue of control rat tongue, although only c-fos mRNA levels tended to be elevated in dysplastic tongue epithelium. Histologically, all 4NQO-induced rat TC were well-differentiated squamous cell carcinomas. Immunostaining for JunB and c-Fos proteins was positive in the nuclei of tumor cells of all TC. It is noteworthy that JunB was negative, but c-Fos was positive in the dysplastic tongue epithelium of the 4NQO-treated rats. Immunostaining for both proteins was negative in tongue mucosal epithelium of control rats. There were no mutations in the coding regions of either junB or c-fos in all the TC examined. These results suggest the possibility that the expressions of junB and c-fos were enhanced stepwise in 4NQO-induced carcinogenesis of rat tongue, and that the coexpression of JunB and c-Fos might play an important role in the establishment of TC.

Abstract
Rats of the DA strain are highly susceptible to 4NQO-induced TCs, whereas WF rats are barely susceptible. In (DA x WF)F2 rats, 5 QTL, Tscc1-5, are responsible for most of the phenotypic variations, though they do not account for all of the phenotypic differences between WF and DA rats. Analysis of 40 tongue tumors >5 mm in diameter from (DA x WF)F1 rats for LOH at the Tscc loci revealed a high frequency of LOH in chromosomal regions where the Tscc2, -3 and -4 loci map. In most cases of LOH, the allele of the barely susceptible WF strain was lost, suggesting that these loci in the WF strain encode tumor-suppressor genes. Analysis of the same tumors for somatic mutations in oncogenes indicated frequent alteration of Ha-ras, which maps in the Tscc3 region, but rare mutation of the p15(INK4B) and p16(INK4A) genes or the p53 and Msh2 genes. Frequent LOH was also found on rat chromosomes 5 (RNO5) and 6 (RNO6). Tumors of large size accumulated LOH at multiple loci, suggesting the involvement of Tscc loci in tumor progression.

Abstract
FUBI (failure of ureteric bud invasion) is a highly inbred strain of mouse with a high spontaneous incidence of uni- or bilateral renal agenesis (60%). Bilateral renal agenesis is lethal within 2 days after birth. The primary defect of FUBI is failure of the ureteric bud to penetrate into the metanephric mesenchyme at around embryonic day 11, resulting in apoptosis of metanephric cells and leading to renal agenesis on the affected side. The metanephros seemed to be normal because co-culturing of the FUBI metanephros with homologous spinal cord induced differentiation of the rudiment, but co-culturing with the homologous ureteric bud frequently did not. Genetic analysis revealed that more than two genes were involved in this malformation and we mapped one of the modifier loci, fubi1, on chromosome 2, at approximately 65 cM from the centromere. In this region, there are two possible candidate genes, Wilms' tumor 1 and formin, that play important roles in kidney development. Some of formin mutants shared a similar phenotype with FUBI; however, there was no difference in the expression of formin in embryonic kidneys between FUBI and control NFS/N mice. Studies of fubi1 congenic mice indicated that interaction of two or more loci is essential for the FUBI phenotype.

Abstract
In our previous study, Dark-Agouti (DA) rats were found to be highly susceptible to 4-nitroquinoline 1-oxide (4NQO)-induced tongue carcinoma (TC), whereas Wistar / Furth (WF) rats were barely susceptible. Interval mapping analysis of reciprocal backcross rats showed two quantitative trait loci (QTL) on rat chromosomes (RNO) 1 and 19. In the present study, a composite interval mapping analysis was applied to 4NQO-induced TC in 130 (DA x WF) F2 rats, demonstrating five independent QTL, Tongue squamous cell carcinoma 1 - 5 (Tscc1 - 5), responsible for phenotypic differences in the size and number of TCs in the two strains. Two of these QTL were mapped on RNO1, and the others were mapped on RNO4, 14, and 19. The DA allele at these loci consistently yielded semidominant susceptibility to TC. Out of the five loci detected in this F2 generation, Tscc1 and 2 were identical to Stc1 and Rtc1 described in our previous study, but the other three were novel. We propose a new nomenclature consistent with their function. Genome-wide screening of the F2 progeny also suggested the presence of three additional QTL on RNO5, 6, and 10. The possible roles of these loci in tongue carcinogenesis are discussed.

Abstract
Oral administration of propylnitrosourea (PNU) in drinking water induces high incidence of lympho-haemopoietic malignancies in rats. Previously we reported that F344 strain rats were highly susceptible to T-lymphomas, and LE/Stm rats, to erythro- or myeloid leukaemias. For analysis of the genetic factors determining types of diseases, we have established LEXF recombinant inbred strains of rats comprising 23 substrains, each derived from intercross between F344 and LE/Stm rats. Rats of 23 LEXF substrains were given PNU, and the development of tumours was observed. The overall incidence of haemopoietic tumours ranged from 100% to 66.7%, and the fractions of T-lymphomas, from 100% to 4%, showing a continuous spectrum. Based on the genetic profile published as a strain distribution pattern table for the LEXF, we screened the potential quantitative trait loci involved in determination of the types of disease and length of the latency period. Statistical calculation was performed using the Map Manager QT software developed by Manly. Four loci, on chromosome 4, 7, 10 and 18, were suggested to associate with the T-lymphoma susceptibility and three loci, on chromosome 1, 5 and 16, with the length of the latency period. These putative loci were further examined in backcross (F344 x LE)F1 x LE. Among seven loci suggested by the recombinant inbred study, three loci, on chromosome 5, 7 and 10, were significantly associated with T-lymphomas and another locus on chromosome 1, just weakly. These observations indicate that PNU-induced lymphomagenesis is a multifactorial genetic process involving a number of loci linked with susceptibility and resistance.

Abstract
The incidence of tongue carcinomas (TCs) induced by oral administration of 4-nitroquinoline 1-oxide in rats is strain dependent. The inbred Dark-Agouti (DA) strain showed a much higher susceptibility to large mass-forming infiltrative TCs than did the Wistar-Furth (WF) strain. Our previous study (M. Kitano et al, Jpn. J. Cancer Res., 87: 1097-1101, 1996) on crosses between these two strains postulated a dominant susceptibility gene in DA and a dominant resistance gene in WF rats. The present study mapped these loci by analyzing the backcrosses to each parent with simple sequence repeat polymorphisms. Five quantitative parameters were analyzed: (a) the number of TCs > 5 mm in diameter; (b) the total number of TCs per rat; (c) the diameter of the largest TCs (DTCmax values); (d) the number of non-TC cancers per rat; and (e) and the number of cancers of any site per rat. All of these parameters were closely correlated (P < 0.0001). DA rats had a semidominant gene (Stc1) favoring the development of 4-nitroquinoline 1-oxide-induced cancers on chromosome 19, closely linked to D19Mit9. Peak linkage was observed 4 cM distal from D19Mit9, with a logarithm of the odds (lod) score of 5.72 for the number of large TCs and 6.08 for the DTCmax. On the other hand, WF rats had a semidominant gene (Rtc1) mapped between D1Mit1 and D1Mit3, approximately 20 cM from D1Mit1, with a peak lod score of 3.30 for both the number of large TCs and the DTCmax. The main effect of Rtc1 seemed to be to reduce the size of the TCs. The action of these genes was dose dependent and cooperative. The final incidence of TC in DA, WF, F1, and backcross rats seemed to be explained by combinations of genotype at these two loci. Possible candidate genes for Stc1 and Rtc1 are discussed.

Abstract
For isolation of mouse mtDNA-less (rho0) cell lines, we searched for various antimitochondrial drugs that were expected to decrease the mtDNA content and found that treatment with ditercalinium, an antitumor bis-intercalating agent, was extremely effective for completely excluding mtDNA in all the mouse cell lines we tested. The resulting rho0 mouse cells were successfully used for trapping the mtDNA of living nerve cells into dividing cultured cells by fusion of the rho0 cells with mouse brain synaptosomes, which represent synaptic endings isolated from nerve cells. With neuronal mtDNA obtained, all of the cybrid clones restored mitochondrial translation activity similarly regardless of whether the mtDNA was derived from young or aged mice, thus at least suggesting that defects in mitochondrial genomes are not involved in the age-associated mitochondrial dysfunction observed in the brain of aged mice. Furthermore, we could trap a very small amount of a common 5823-base pair deletion mutant mtDNA (DeltamtDNA5823) that was detectable by polymerase chain reaction in the cybrid clones. As the amount of mutant mtDNA with large scale deletions was expected to increase during prolonged cultivation of the cybrids, these cells should be available for establishment of mice containing the deletion mutant mtDNA.

A single dominant gene Tlsm-1 was found to determine the type of spontaneous lymphomas to be T in the cross between AKR/Ms and SL/Kh. Microsatellite analysis mapped Tlsm-1 at the position 61 cM from centromere of Chr. 7. Study of this segment of T-lymphoma prone AKXD Rl strains also showed association of Tlsm-1 with T-lymphomas. On the other hand, lymphoma latency was significantly shorten by a recessive gene lla of SL/Kh. By a quantitative trait analysis, lla was located in class II gene in MHC.

Abstract
In a yeast artificial chromosome contig close to the nude locus on mouse chromosome 11, we identified a novel gene, nucleoredoxin, that encodes a protein with similarity to the active site of thioredoxins. Nucleoredoxin is conserved between mammalian species, and two homologous genes were found in Caenorhabditis elegans. The nucleoredoxin transcripts are expressed in all adult tissues examined, but restricted to the nervous system and the limb buds in Day 10.5-11.5 embryos. The nucleoredoxin protein is predominantly localized in the nucleus of cells transfected with the nucleoredoxin expression construct. Since the bacterially expressed protein of nucleoredoxin showed oxidoreductase activity of the insulin disulfide bonds with kinetics similar to that of thioredoxin, it may be a redox regulator of the nuclear proteins, such as transcription factors.

Abstract
We analyzed the incidence of infiltrative mass-type tongue carcinomas (IMTC) induced in 550 rats by continuous oral administration of 0.001% 4-nitroquinoline 1-oxide solution for 180 days. The study included various crosses of susceptible Dark-Agouti rats (DA) and resistant Wistar/Furth rats (WF). DA showed a 93.6% incidence of IMTC measuring more than 5 mm in their largest diameter, while WF showed only a 4% incidence. Reciprocal F1 and F2 hybrids mated by DA and WF showed 47.5% and 45.8% incidences, respectively. Meanwhile, reciprocal backcrossed hybrids to DA and WF showed 73.7%, and 24.6% incidences, respectively. Segregation of the incidences suggests that there are two autosomal dominant genes, one linked to the susceptibility of DA and the other to the resistance of WF.

Abstract
The effects of two host genes on retrovirus-induced murine lymphoma were evaluated by studying 114 F2 intercross mice between SL/Kh and AKR/Ms mice. Out of 47 T-lymphoma-bearing F2 mice, 45 had the AKR-derived dominant allele at Tism-1. The length of the lymphoma latent period was not related to type of tumor. Instead, it was significantly shortened by a recessive SL/Kh-derived allele at a major histocompatibility complex (MHC)-linked locus on Chr. 17. A quantitative trait analysis of the latent period yielded a maximal logarithm of likelihood ratio for linkage (LOD) score of 7.06 at a class II gene within MHC. The SL/Kh-derived recessive gene was named lla (lymphoma latency acceleration).

Abstract
The murine spontaneous B lymphoma is etiologically related to the expression of endogenous ecotropic murine leukemia virus (ETV). Although both SL/Kh and SL/Ni mouse strains show a high level of expression of ETV from early in life, the former is a pre-B lymphoma-prone strain and the latter is rather lymphoma-resistant. In order to identify the host background difference related to the lymphomagenesis, we performed a genetic cross study between these two strains. In the reciprocal F1 generation, the length of the lymphoma latent period was slightly but significantly longer in (SL/Ni xSL/Kh)F1 than in (SL/KhxSL/Ni)F1(P < 0.05). The incidence of overall lymphomas and that of acute pre-B lymphomas was lower in (SL/NixSL/Kh)F1 than in (SL/KhxSL/Ni)F1, although the difference was not statistically significant. These observations indicate that an epigenetic maternal resistance mechanism of SL/Ni mice plays a role in the lymphoma resistance. Furthermore, in the backcross combinations without maternal influence of SL/Ni, we observed a genetic mechanism of lymphoma resistance: an SL/Ni-derived recessive lymphoma-resistance gene mapped in the proximal segment of Chr. 4. We named this gene nir-1 (SL/Ni-lymphoma resistance-1). Thus, we have demonstrated epigenetic and genetic mechanisms of lymphoma resistance of the SL/Ni mouse with the high expression of endogenous ETV.

Abstract
We examined age-associated changes of respiratory enzyme activities and protein synthesis in mitochondria isolated from mouse brain with high oxidative activities. Cytochrome c oxidase activity increased unexpectedly with aging, while the mitochondrial translational activities showed two phases of alterations: they increased progressively up to 21 weeks after birth followed by a gradual decrease with aging. Results showed that these changes were not due to the change in mitochondrial DNA (mtDNA) copy number or the accumulation of deletion mutations in mtDNA. These observations suggest that the common feature of age-associated changes in both human and mouse mitochondrial functions is limited to the decrease in mitochondrial translational activity. Therefore, mouse brain can be used as a model to understand the relationships between aging and mitochondrial function by examining the cause of decrease in mitochondrial translation activity.

Abstract
Expression of ras p21 oncoproteins in human ovarian carcinomas was examined immunohistochemically by using a monoclonal antibody(clone RAS 10) with respect to the degree of their histological differentiation. To achieve this, the intensity of staining for the protein was compared between undifferentiated and well differentiated carcinomas, i.e. extreme subtypes of common epithelial carcinomas. The former was composed of 8 "solid" carcinomas and the latter, 11 serous, 8 mucinous, 4 endometrioid and 4 clear cell carcinomas. All the cases examined, including both undifferentiated and well-differentiated carcinomas, showed a positive reaction to this antibody. Staining intensity and the number of positive cells somewhat varied among the cases. Additionally, 2 cases of ovarian epithelial tumors of low malignant potential (I,MP) were stained with this antibody. Both the cases were positive, but the number of positive cells seemed to be rather less than that found in the carcinoma groups. Thus, no differences in ras p21 expression were observed between the cases examined in spite of the differences in the degree of differentiation of the epithelial ovarian carcinomas. However, the possibility remained that the number of positive cells could be an indicator of malignant potential, enabling us to distinguish LMPs from carcinomas.
