Phenotypes Associated with This Genotype

Genotype
MGI:6108175

• Allelic Composition: Apc^Min/Apc⁺; Hltf^tm1.1Hdin/Hltf^tm1.1Hdin
• Genetic Background: involves: 129 * C57BL/6 * FVB/N

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

cellular

chromosomal instability ( J:252991 )

• aneuploidy owing to nonreciprocal translocations, chromosomal fusions (dicentric chromosomes, centromeric fusions, missing telomeres) and chromosomal fragments and breaks in cultured colon tumor cells

neoplasm

neoplasm ( J:252991 )

N • average 65 macroscopic intestine adenocarcinoma tumors per mouse, similar to wild-type

N • average 1.5 macroscopic colon adenocarcinoma tumors per mouse, similar to wild-type

increased metastatic potential ( J:252991 )

• invasive intestinal adenocarcinomas (deeper invasion of tumor cells into muscularis propria of small intestine)

• high beta-catenin activity in invaded neoplastic glandular cells in small intestine

• most colon tumors displayed a more severe glandular atypia resulting in formation of many mucin-filled cysts

• most colon tumors displayed strong desmoplastic stromal reaction

• higher beta-catenin activity in colon tumor cells

• transplanted colon tumor cells are malignant
