"Lipopolysaccharide (LPS) induces proliferation of splenic B-cells, and this response was found to be significantly lower in A/J than in C57BL/6J (B6) mice. Several strains and substrains mirrored the high and low responses of B6 and A/J. Assessment of 26 AXB/BXA recombinant inbred (RI) mouse strains identified 23 strains with a low (A/J-like), high (B6-like), or intermediate response. The three remaining RI strains exhibited a novel hyperresponsive phenotype significantly different from that of either founder strain. RI analysis identified four suggestive loci contributing to the LPS response, two of which were confirmed by analysis of congenic strains containing the donor genomic segment from a high- or low-responder strain on the opposite background. The combination of A/J and B6 alleles fixed to homozygosity at the four suggestive loci would occur in only 1 of 256 intercross progeny, but occurred several times among the RI strains."

" "Previous work has identified inherent behavioral, neuroendocrine, and biochemical differences among inbred rodent strains that have been related to the animals' differential responsiveness to drugs of abuse or stress. In the present study, we sought to determine (1) whether there are genetic correlations among particular phenotypic traits that differ between a pair of inbred rat strains (Lewis and Fischer 344) or a pair of inbred mouse strains (A/J and C57BL/6J); (2) which of these traits might be amenable to quantitative trait locus analysis; and (3) whether additional behavioral or biochemical differences relevant to drug- or stress-responsiveness could be identified in these strains. Specifically, we measured several behavioral, neuroendocrine, and biochemical traits in parental Lewis and Fischer 344 rats and in 298 members of an F2 intercross population, as well as in parental A/J and C57BL/6J mice and in 11 of the AXB/BXA recombinant inbred mouse strains. Traits measured included exploratory locomotor activity in a novel environment; amphetamine-induced locomotor activity; several specific protein levels in striatal regions, including inhibitory G protein subunits, the dopamine transporter, the Fos family member transcription factor DeltaFosB, and the protein phosphatase inhibitor DARPP-32; and late-afternoon plasma corticosterone concentrations. Each of the traits measured in F2 rats or recombinant inbred mice appears to be influenced by multiple genes, as well as by environmental factors. There were statistically significant, albeit relatively weak, correlations among several traits in an F2 intercross population bred from Lewis and Fischer rats. Among the traits studied in Lewis and Fischer rats, one seemed most amenable to quantitative trait locus analysis: the level of the inhibitory G-protein subunit, Galphai, in the nucleus accumbens. We also found a robust genetic correlation between levels of DeltaFosB and levels of the dopamine transporter in striatal regions in AXB/BXA recombinant inbred mouse strains. While these studies demonstrate the likely complexity of the genetic factors that influence the numerous phenotypes associated with altered responsiveness to drugs of abuse and stress, they represent an initial and necessary step toward identifying specific genetic factors involved."

"The mRNA levels for the mitochondrial uncoupling protein (UCP1) in fat tissues of A/J and C57BL/6J inbred strains of mice varied in a regional-specific manner after stimulation of adrenergic signaling by cold exposure or treatment with a beta3-adrenergic agonist. While the differences between strains were minimal in interscapular brown fat, large differences occurred in white fat tissues, particularly in retroperitoneal fat. Among the AXB recombinant inbred strains, the Ucp1 mRNA levels varied up to 130-fold. This large induction at the mRNA level was accompanied by a corresponding increase in brown adipocytes as revealed by immunohistology with anti-UCP1 antibodies. A high capacity to induce brown fat in areas of traditional white fat had no impact on the ability to gain weight in response to high fat and sucrose diets, but did correlate with the loss of weight in response to treatment with a beta3-adrenergic agonist (CL 316,243). This genetic variation in mice provides an experimental approach to identify genes controlling the induction of brown adipocytes in white fat tissues.

Among the AXB recombinant inbred strains, the Ucp1 mRNA levels varied up to 130-fold. This large induction at the mRNA level was accompanied by a corresponding increase in brown adipocytes as revealed by immunohistology with anti-UCP1 antibodies. A high capacity to induce brown fat in areas of traditional white fat had no impact on the ability to gain weight in response to high fat and sucrose diets, but did correlate with the loss of weight in response to treatment with a beta3-adrenergic agonist (CL 316,243). This genetic variation in mice provides an experimental approach to identify genes controlling the induction of brown adipocytes in white fat tissues.

Previous studies using mouse models have examined only very small portions of the genome. Here we report the findings of a genome-wide search for susceptibility genes for teratogen-induced clefting in the AXB and BXA set of recombinant inbred mouse strains. We compare results obtained using phenytoin (which induces cleft lip) and 6-aminonicotinamide (which induces cleft palate). We use a new statistical approach based on logistic regression suitable for these categorical data to identify several chromosomal regions as possible locations of clefting susceptibility loci, and we review candidate genes located within each region. Because cleft lip and cleft palate do not frequently co-aggregate in human families and because these structures arise semi-independently during development, these disorders are usually considered to be distinct in etiology. Our data, however, implicate several of the same chromosomal regions for both forms of clefting when teratogen-induced. Furthermore, different parental strain alleles are usually associated with clefting of the lip versus that of the palate (i.e., allelic heterogeneity).

Quantitative Trait Locus (QTL) analysis was used to provide provisional location of QTLs for alcohol consumption. The inbred strains were screened for levels of alcohol intake (calculated as alcohol preference and absolute alcohol consumption) by receiving 4 days of forced exposure to a 10% (wt/vol) solution of alcohol, followed by 3 weeks of free choice between water and 10% alcohol. A wide and continuous distribution of values for alcohol consumption and preference was obtained in the AXB/BXA RI strains, confirming polygenic influences on alcohol-related behaviors. Significant gender differences were found for both alcohol preference [F28,651 = 2.12, p < 0.001] and absolute alcohol consumption [F28,647 = 2.57, p < 0.001]. In males, putative QTLs were mapped to chromosomes (Chrs) 2, 5, 7, 10, 11, and 16. Multiple regression analysis indicated that approximately 75% of the genetic variance in alcohol preference in males could be accounted for by three of the QTL regions. Several of the putative QTLs appeared to be male-specific (Tyr on Chr 7; D10Mit126 on Chr 10; D11Mit61 on Chr 11). In females, seven putative QTLs were mapped to Chrs 2, 4, 5, 7, 11, 16, and 19.

The genetic basis of variation in eye size in mice was explored, and genes that modulate eye weight, lens weight, and retinal area were mapped. METHODS: Eyes of approximately 700 mice were weighed. Data were corrected by regression analysis to eliminate effects of sex, age, and body weight. Interval mapping was used to locate quantitative trait loci (QTLs) using recombinant inbred strains and F2 intercrosses between strains C57BL/6J and DBA/2J. RESULTS: Major QTLs were discovered near the centromere of chromosome 5 (Eye1: genomewide P E 0.005) and on proximal chromosome 17 near the mast cell protease 6 gene (Eye2, P ] 0.05). Both QTLs have significant effects on eye size, lens weight, and retinal area. The DBA/2J alleles at Eye1 and Eye2 are partially dominant and increase eye weight by as much as 1.0 mg. Analysis of 183 F2 progeny confirmed and refined the chromosomal assignments of both Eye1 and Eye2. CONCLUSIONS: Eye1 and Eye2 are the first loci known to control normal variation in eye size in any mammal. The hepatic growth factor gene (Hgf), a potent mitogen expressed in the retina, pigment epithelium, and choroid, is a strong candidate for Eye1.

"Helicobacter hepaticus is a naturally occurring pathogen of mice and has been used to develop models of chronic hepatitis, liver cancer, and, more recently, inflammatory bowel disease, in selected mouse strains. A/JCr mice are particularly susceptible to H. hepaticus-induced hepatitis and subsequent development of liver neoplasms, whereas C57BL/6 mice are resistant. In this study, we inoculated nine AXB recombinant inbred (RI) mouse strains, derived from A/J and C57BL/6 mice, with H. hepaticus to determine the genetic basis of resistance to Helicobacter-induced liver disease. Mice were surveyed 14 months after inoculation by culture and PCR for H. hepaticus colonization of the liver and cecum, and microscopic morphometric evaluations of the liver were performed to quantify and correlate the severity of inflammation, apoptosis, and proliferation. Analysis of variance of hepatic inflammation demonstrated significant variation among the RI strains (P < 0.0001), and the strain distribution pattern suggested a multigenic basis of disease resistance. Quantitative trait analysis using linear regression suggested possible linkage to loci on mouse chromosome 19. Hepatocellular and biliary epithelial apoptosis and proliferation indices, including proliferation of oval cells, were markedly increased and correlated with severity of inflammation. Prevalence of hepatic neoplasia was also increased in susceptible RI strains. These findings demonstrate a genetic basis for susceptibility to Helicobacter-induced disease and provide insight into its pathogenesis.

"A crucial aspect of the inflammatory response is the recruitment of activated neutrophils (PMN) to the site of damage. Lytic enzymes and oxygen radicals released by PMN are important in clearing an infection or cellular debris, but can also produce host tissue damage. Failure to properly regulate the inflammatory response contributes to a variety of human diseases like sepsis and multiple organ dysfunction syndrome, the leading cause of morbidity and mortality in surgical intensive care units. Many aspects of human disease pathology, including hepatic PMN infiltration, can be recapitulated in mice using an endotoxic shock model. Six quantitative trait loci that predispose to high infiltration of PMN in hepatic sinusoids after high-dose endotoxin administration were provisionally identified. Two of these loci, Hpi1 and Hpi2 on mouse chromosomes 5 and 13, were mapped to the significant and highly significant level using a low-resolution genome scan on 122 intercross animals. These loci interact epistatically to produce a high degree of PMN infiltration. Intercross and recombinant inbred strain mice with a specific genotype at these loci always had a high infiltration response, indicating that genotype analysis at just these two loci can accurately predict a high PMN infiltration response. Genetic predisposition to the degree of PMN infiltration in the inflammatory response in mice suggests that analogous genetic mechanisms occur in human beings that could be used for diagnostic purposes."

"Among a selected group of mouse strains susceptible to dietary obesity, those with an enhanced capacity for Ucp1 and brown adipocyte induction in white fat preferentially lost body weight following adrenergic stimulation. Based on the generality of this mechanism for reducing obesity, a genetic analysis was initiated to identify genes that control brown adipocyte induction in white fat depots in mice. Quantitative trait locus (QTL) analysis was performed using the variations of retroperitoneal fat Ucp1 mRNA expression in progeny of genetic crosses between the A/J and C57BL/6J parental strains and selected AXB recombinant inbred strains. Three A/J-derived loci on chromosomes 2, 3, and 8 and one C57BL/6J locus on chromosome 19 were linked to Ucp1 induction in retroperitoneal fat. Although A/J-derived alleles seemed to contribute to elevated Ucp1 expression, the C57BL/6J allele on chromosome 19 increased Ucp1 mRNA to levels higher than parental values. Thus, novel patterns of C57BL/6J and A/J recombinant genotypes among the four mapped loci resulted in a transgressive variation of Ucp1 phenotypes. Although the extent of the interchromosomal interactions have not been fully explored, strong synergistic interactions occur between a C57BL/6J allele on chromosome 19 and an A/J allele on chromosome 8. In addition to selective synergistic interactions between loci, variations in recessive and dominant effects also contribute to the final levels of Ucp1 expression."

When splenic and peritoneal macrophages from these two mouse strains were infected in vitro with Mycobacterium smegmatis, the Bcgr macrophages were shown to inactivate M. smegmatis more efficiently than their Bcgs congenic counterparts. The mechanisms of this superior antimycobacterial activity was studied further. Addition of catalase did not abolish killing to a significant degree in either allelic type of macrophage, suggesting that hydrogen peroxide production was not involved in the killing activity controlled by the Bcg gene. Activation of Bcgs macrophages by exposure to crude lymphokines rendered them equally as efficient as their Bcgr counterparts in their capacity to destroy M. smegmatis. This finding suggests that both the genetically resistant and susceptible macrophages have the potential to kill M. smegmatis in vitro. This potential is expressed constitutively by the Bcgr but not Bcgs macrophages and can be induced, by lymphokine treatment, in the Bcgs macrophages. In a final set of experiments, the macrophage killing of M. smegmatis was evaluated as a test system to type for the Bcg gene allelic type in vitro, using a set of AXB and BXA recombinant inbred strains of mice. Results obtained show that typing of AXB/BXA recombinant inbred strains for the trait of bactericidal activity vs. M. smegmatis in vitro revealed a perfect match with the strain distribution pattern of resistance/susceptibility to Mycobacterium " J Leukoc Biol 1990 Jan "Denis M, Forget A, Pelletier M, Gervais F, Skamene E.

B6 adrenals exhibited abundant CS-positive cells in cord-like arrays while A/J adrenals contained fewer, randomly arranged CS-positive cells. To quantify these results, each adrenal cortex was divided into eight sectors and each sector was classified as to phenotype. Ninety-three percent of the sectors of B6 cortices exhibited the cord-like pattern, whereas only 15% of the sectors of A/J cortices exhibited this pattern. These differences are consistent with a hypothesis that A/J mice are relatively deficient in the prophylactic activities of endogenous glucocorticoids. Adrenal glands from (C57BL/6J x A/J)F1 hybrid mice had approximately equal proportions of areas exhibiting each phenotype, indicating codominant alleles for this trait. We propose the name Cor for this gene. Thirty AXB and BXA recombinant inbred (RI) lines of mice derived from A/J and B6 progenitors were examined for CS immunostaining. Twenty-eight of them had either predominantly A/J-like or predominantly B6-like phenotypes. These RI data support either of two hypotheses. Hypothesis 1 emphasizes the nearly complete concordance of the RI lines with progenitor phenotypes and proposes that a single Cor gene regulates the distribution of CS-positive cells. Using this model, the strain distribution among RI lines implies linkage of Cor to a region on chromosome 6, 27-37 cM from the centromere. Hypothesis 2, which gives greater weight to the two RI lines with intermediate numbers of CS-positive cells, postulates an epistatic interaction between two Cor loci.

"The development of a mouse acquired immunodeficiency syndrome (MAIDS) induced following LP-BM5 MuLV infection depends on host genetic factors. Susceptible mice, such as C57BL/6J mice, develop a profound impairment of lymphoproliferative response to mitogens and hyperplasia of lymphoid organs and succumb to infection within 6 months. These changes do not occur in resistant mice, such as A/J mice. Resistance to MAIDS is a dominant trait since (C57BL/6J x A/J)F1 hybrid mice did not develop any immune dysfunctions following infection. Genetic regulation of the trait of resistance/susceptibility to MAIDS was determined in AXB/BXA recombinant inbred (RI) mouse strains (derived from resistant A/J and susceptible C57BL/6J progenitors). Two different criteria were used to determine their resistance or susceptibility to developing MAIDS: the gross pathologic evaluation of lymphoid organs at 13-15 weeks of infection, and survival. RI mouse strains segregated into two non-overlapping groups. The first group did not develop any significant pathology, and these mouse strains were considered as resistant to MAIDS. The second group showed the virus-induced pathological changes as well as an immunological dysfunction as seen in C57BL/6J progenitor mice, and these strains were thus considered as susceptible to MAIDS. This bimodal strain distribution pattern of resistance/susceptibility to MAIDS among the RI strains suggests that this phenotype is controlled by a single gene. Linkage analysis with other allelic markers showed a strong association between resistance/susceptibility to MAIDS and the H-2 complex. Possession of the H-2b haplotype derived from C57BL/6J mice was associated with susceptibility to MAIDS, while the H-2a haplotype conferred resistance to the disease. This finding was confirmed by demonstrating that H-2a congenics on the susceptible C57BL/10 background were as resistant to MAIDS as A/J mice which donated the H-2a locus. Gene(s) within the H-2 complex thus represent the major regulatory mechanism of resistance/susceptibility to MAIDS.

"The development of a mouse acquired immunodeficiency syndrome (MAIDS) induced following LP-BM5 MuLV infection depends on host genetic factors. Susceptible mice, such as C57BL/6J mice, develop a profound impairment of lymphoproliferative response to mitogens and hyperplasia of lymphoid organs and succumb to infection within 6 months. These changes do not occur in resistant mice, such as A/J mice. Resistance to MAIDS is a dominant trait since (C57BL/6J x A/J)F1 hybrid mice did not develop any immune dysfunctions following infection. Genetic regulation of the trait of resistance/susceptibility to MAIDS was determined in AXB/BXA recombinant inbred (RI) mouse strains (derived from resistant A/J and susceptible C57BL/6J progenitors). Two different criteria were used to determine their resistance or susceptibility to developing MAIDS: the gross pathologic evaluation of lymphoid organs at 13-15 weeks of infection, and survival. RI mouse strains segregated into two non-overlapping groups. The first group did not develop any significant pathology, and these mouse strains were considered as resistant to MAIDS. The second group showed the virus-induced pathological changes as well as an immunological dysfunction as seen in C57BL/6J progenitor mice, and these strains were thus considered as susceptible to MAIDS. This bimodal strain distribution pattern of resistance/susceptibility to MAIDS among the RI strains suggests that this phenotype is controlled by a single gene.
