Delayed onset of Igf2-induced mammary tumors in Igf2r transgenic mice.
The insulin-like growth factor-II (IGF-II) receptor (IGF2R) regulates the level or activity of numerous proteins, including factors that control growth and differentiation. Frequent loss or inactivation of this receptor in a diverse group of tumors indicates that it may act as a tumor suppressor, but it is not known which functions of this receptor are selected against in the tumors. Lysosomal ...
متن کاملMammary Tumors in Transgenic Mice
Heterozygous female mice carrying a targeted mutation of the Ets2 transcription factor gene were mated with a mouse strain that develops mammary tumors due to the expression of the polyoma virus middle T oncogene. Tumors from females with only one wild-type Ets2 gene were approximately one-half the size of tumors from controls. The smaller size of the tumors was correlated with a more different...
متن کاملProtein tyrosine phosphatase epsilon increases the risk of mammary hyperplasia and mammary tumors in transgenic mice.
Accurate phosphorylation of tyrosine residues in proteins plays a central role in regulation of cellular function. Although connections between aberrant tyrosine kinase activity and malignancy are well-established, significantly less is known about the roles of protein tyrosine phosphatases (PTPases) in tumorigenesis. We have previously shown that the transmembranal form of PTPase Epsilon (PTPe...
متن کاملMouse mammary tumor virus c-rel transgenic mice develop mammary tumors.
Amplification, overexpression, or rearrangement of the c-rel gene, encoding the c-Rel NF-kappaB subunit, has been reported in solid and hematopoietic malignancies. For example, many primary human breast cancer tissue samples express high levels of nuclear c-Rel. While the Rev-T oncogene v-rel causes tumors in birds, the ability of c-Rel to transform in vivo has not been demonstrated. To directl...
متن کاملEvolution of somatic mutations in mammary tumors in transgenic mice is influenced by the inherited genotype
BACKGROUND MMTV-Wnt1 transgenic mice develop mammary hyperplasia early in development, followed by the appearance of solitary mammary tumors with a high proportion of cells expressing early lineage markers and many myoepithelial cells. The occurrence of tumors is accelerated in experiments that activate FGF proto-oncogenes or remove the tumor suppressor genes Pten or P53, implying that secondar...
