An unbiased proteomic screen to identify integrin-linked kinase (ILK) interactors revealed rictor as an ILK-binding protein. This finding was interesting because rictor, originally identified as a regulator of cytoskeletal dynamics, is also a component of mammalian target of rapamycin complex 2 (mTORC2), a complex implicated in Akt phosphorylation. These(More)
Multiple lines of evidence suggest that increased production and/or deposition of the beta-amyloid peptide, derived from the amyloid precursor protein, contributes to Alzheimer's disease. A growing list of neurotransmitters, growth factors, cytokines, and hormones have been shown to regulate amyloid precursor protein processing. Although traditionally(More)
Cell attachment and the assembly of cytoskeletal and signaling complexes downstream of integrins are intimately linked and coordinated. Although many intracellular proteins have been implicated in these processes, a new paradigm is emerging from biochemical and genetic studies that implicates integrin-linked kinase (ILK) and its interacting proteins, such(More)
Integrin-linked kinase (ILK) is a serine/threonine protein kinase that plays an important role in integrin signaling and cell proliferation. We used Cre recombinase (Cre)-loxP technology to study CNS restricted knock-out of the ilk gene by either Nestin-driven or gfap-driven Cre-mediated recombination. Developmental changes in ilk-excised brain regions are(More)
Histopathological studies suggest that the stem cells of human teratomas may be classified into two major categories: nullipotent stem cells, and multipotent stem cells, capable both of self-renewal and differentiation into a wide range of somatic and extraembryonic cell types. We have isolated a multipotent stem cell clone from the human teratoma cell line(More)
Clinical and experimental data indicate that human embryonal carcinoma cells are unusually sensitive to the antitumor drug cis-diamminedichloroplatinum(II) (cisplatin), but the basis of this sensitivity is unknown. Using colony formation assays we measured survival of cultured human embryonal carcinoma cells following cisplatin treatment and related(More)
The chemotherapeutic response of a series of patients with bronchial carcinoma has been compared with the response of their xenografts established in immune-suppressed mice. The in situ endpoint of growth delay in subcutaneous tumours was the main parameter used to assess xenograft response, but clonogenic cell survival studies were also performed to assess(More)
Differential display-PCR (DDPCR) was used to identify a Streptococcus pneumoniae gene with enhanced transcription during growth in the murine peritoneal cavity. Northern dot blot analysis and comparative densitometry confirmed a 1.8-fold increase in expression of the encoded sequence following murine peritoneal culture (MPC) versus laboratory culture or(More)
Glutamate is the principal excitatory neurotransmitter in the mammalian brain. Several lines of evidence suggest that glutamatergic hypoactivity exists in the Alzheimer's disease brain, where it may contribute to both brain amyloid burden and cognitive dysfunction. Although metabotropic glutamate receptors have been shown to alter cleavage of the amyloid(More)
Human embryonal carcinoma cells sometimes display the developmental potential of early embryonic stem cells. While available data do not clearly identify a counterpart of these tumor cells in normal development, previous comparisons of human embryonal carcinoma and yolk sac carcinomas indicated that these cell types are closely related, and suggested that(More)
