Gene 1043 Changes that may be related to genotype:
ES cells derived from the 129/OlaHsd mouse substrain were used to generate chimeric mice. F1 mice were generated by breeding with C57BL/6 females. The resultant F1N0 heterozygotes were backcrossed to C57BL/6 mice to generate F1N1 heterozygotes. F2N1 homozygous mutant mice were produced by intercrossing F1N1 heterozygous males and females. As this gene is X-linked, the cohort consists of homozygous mutant females, hemizygous mutant males (-/0), heterozygous control females, and wild-type control males (+/0). No wild-type females or heterozygous males were analyzed for this target, as such mice cannot be generated from a male -/0 x female -/+ mating. Female homozygous mutant mice, male hemizygous mutant mice, female heterozygous control mice, and male wild-type control mice were evaluated by the following examinations or tests:
When compared to age- and gender-matched wild-type control mice, hemizygous mutant males had elevated Glucose levels. |

Gene
1043 Taqman Summary: Moderate levels of RNA
transcripts are detectable in: cerebellum, lung, liver, pancreas, kidney,
thymus, bone marrow, skin, gallbladder, urinary bladder, pituitary gland,
adrenal gland, salivary gland, colon, epididymis, seminal vesicle,
coagulating gland, uterus and white fat. LacZ Summary: As this gene is X-linked, the cohort consists of a hemizygous mutant male (-/0) and a heterozygous female (+/-). LacZ
expression was not detected in: spinal cord, sciatic nerve, eyes,
thymus, spleen, lymph nodes, bone marrow, aorta, heart, lung, liver,
pancreas, kidney, urinary bladder, thyroid gland, parathyroid gland,
pituitary gland, adrenal glands, skeletal muscle, skin, testis, prostate
gland, ovary, uterus and cervix. |
Gene
1043 There were no significant differences detected in the female homozygous and male hemizygous mutant mice when compared with age- and gender-matched heterozygous and wild-type control mice. The following mice were necropsied. Body weight, body length, and organ weights were obtained, and gross pathological findings were recorded. 49 Day Cohort Mouse ID numbers
are as follows: Necropsy Findings: There were no genotype-related or biologically significant differences noted between mutant and wild-type control mice for any of the parameters evaluated at necropsy. Incidental lesions were present in some tissues. These findings were considered to represent background lesions occasionally seen in this strain of mice, lesions due to spontaneous disease, age-related lesions, and/or lesions of a nonspecific etiology. They were not considered to be related to genotype. Body and Organ Weight Findings: Differences in body length, body weight, organ weights, and/or organ weight to body weight ratios were present between individual mice. The variability between mice usually fell within our historical reference ranges and was not correlated with genotype. |
Gene
1043 There were no significant differences detected in the female homozygous and male hemizygous mutant mice when compared with age- and gender-matched heterozygous and wild-type control mice. Tissues from the following mice were evaluated histologically. 49 Day Cohort Mouse ID numbers
are as follows: The following tissues were examined and considered to have no genotype-related abnormality: brain, pituitary gland, ears, nasal cavity, salivary glands, oral cavity, lymph nodes, aorta, lungs, liver, gallbladder, pancreas, spleen, kidneys, urinary bladder, stomach, small and large intestines, larynx, esophagus, trachea, thyroid gland, thymus gland, tongue, skeletal muscle, sciatic nerve, mammary glands, vertebrae, spinal cord, bone (skull, sternum, femur, tibia, and stifle joint), reproductive tract (including gonads), eyes, Harderian glands, integumentary system (skin and either clitoral or preputial glands), and bone marrow. Bone marrow was examined in
sections of sternum, vertebrae, and/or femur and tibia. Marrow cellularity,
myeloid:erythroid (M:E) ratio, myeloid and erythroid maturation sequences,
and numbers of megakaryocytes were evaluated. |
Gene
1043 There were no significant
differences in the homozygous or hemizygous mutant mice when compared
with age- and gender-matched heterozygous or wild-type control mice. Blood samples from the following
mice were evaluated by a complete blood count and differential cell count. 49 Day Cohort Mouse ID numbers
are as follows: |

Serum samples from the following mice were evaluated by a clinical chemistry panel. 49

Gene
1043 There were no significant differences detected in the homozygous mutant mice when compared with age- and gender-matched wild-type control mice. The following mice were evaluated by dual-energy x-ray absorptiometry. 49
Day Cohort Mouse ID numbers are as follows: Bone Mineral Density (BMD in g/cm2 ), fat % (fat percentage expressed as a percentage of body soft tissue compartment), and R-value of soft tissue were calculated from Bone Mineral Content (BMC in g), bone and tissue areas (cm2 ), and total tissue mass (g) generated by a PIXImus densitometer. Densitometric Findings: Incidental densitometric differences were present between some mice. These findings were considered to represent background differences occasionally seen in this strain of mice, differences due to spontaneous disease, age-related differences, and/or differences of a nonspecific etiology. They were not considered to be genotype related. |
Gene
1043 There were no significant
differences detected in the female homozygous and male hemizygous mutant mice
when compared with age- and gender-matched heterozygous and wild-type control
mice. The following mice were evaluated
by physical examination. 49 Day Cohort Mouse ID numbers
are as follows: Individual mutant mice had only occasional minor differences in observed physical features compared to heterozygous and wild-type control mice. These findings are considered to represent individual variability, background features occasionally seen in this strain of mice, findings due to spontaneous disease, age-related findings, and/or findings of a nonspecific etiology. However, none of these differences was regarded as biologically significant or genotype related. |
Gene 1043 Three hemizygous mutant males and three homozygous mutant females were set up in a fertility mating one on one with each other at seven to ten weeks of age. The first mating pair (330253 and 341602) had no pups. The number of pups born from three litters of the second (330255 and 341607) and third (330256 and 341625) mating pairs was recorded. Three weeks later, the live pups were counted and weaned. Mouse ID numbers are as follows: 3 homozygous mutant females (341602, 341607, 341625)
