The PTEN tumor suppressor and effects of Pten disruption in mice (2000)

Podsypanina, Katrina

Cancer is the second leading cause of death in the United States. Neoplastic transformation is caused by genetic and epigenetic alterations in tumor suppressor genes or protooncogenes. This thesis...

Mutation of Pten/Mmac1 in mice causes neoplasia in multiple organ systems

Podsypanina, Katrina, Ellenson, Lora Hedrick, Nemes, Adriana, Gu, Jianguo, Tamura, Masahito, Yamada, Kenneth M., ...

The 3′-untranslated region of CaMKIIα is a cis-acting signal for the localization and translation of mRNA in dendrites

Mayford, Mark, Baranes, Danny, Podsypanina, Katrina, Kandel, Eric R.

Neuronal signaling requires that synaptic proteins be appropriately localized within the cell and regulated there. In mammalian neurons, polyribosomes are found not just in the cell body, but also in...

An inhibitor of mTOR reduces neoplasia and normalizes p70/S6 kinase activity in Pten+/− mice

Podsypanina, Katrina, Lee, Richard T., Politis, Chris, Hennessy, Ian, Crane, Allison, Puc, Janusz, ...

PTEN phosphatase acts as a tumor suppressor by negatively regulating the phosphoinositide 3-kinase (PI3K) signaling pathway. It is unclear which downstream components of this pathway are necessary...

Haploinsufficiency of the Pten tumor suppressor gene promotes prostate cancer progression

Kwabi-Addo, Bernard, Giri, Dipak, Schmidt, Karen, Podsypanina, Katrina, Parsons, Ramon, Greenberg, Norman, ...

The PTEN gene encodes a lipid phosphatase that negatively regulates the phosphatidylinositol 3-kinase pathway and is inactivated in a wide variety of malignant neoplasms. High rates of loss of...

Evidence that transgenes encoding components of the Wnt signaling pathway preferentially induce mammary cancers from progenitor cells

Li, Yi, Welm, Bryan, Podsypanina, Katrina, Huang, Shixia, Chamorro, Mario, Zhang, Xiaomei, ...

Breast cancer is a genetically and clinically heterogeneous disease, and the contributions of different target cells and different oncogenic mutations to this heterogeneity are not well understood....

Changes in gene expression during the development of mammary tumors in MMTV-Wnt-1 transgenic mice
