We report the characterization of Cep170, a forkhead-associated (FHA) domain protein of previously unknown function. Cep170 was identified in a yeast two-hybrid screen for interactors of Polo-like kinase 1 (Plk1). In human cells, Cep170 is constantly expressed throughout the cell cycle but phosphorylated during mitosis. It interacts with Plk1 in vivo and(More)
Despite the commonly held view that flatfish can change their surface markings to match their background pattern, there have been few systematic studies and it has recently been claimed that their capacity for such adaptive changes is minimal. Here we show that the tropical flatfish Bothus ocellatus can achieve pattern-matching with surprising fidelity. By(More)
Human cervix cancer is caused by high-risk human papillomaviruses encoding E6 and E7 oncoproteins, each of which alter function of distinct targets regulating the cell cycle, apoptosis, and differentiation. Here we determined the molecular contribution of E6 or E7 to neoplastic progression and malignant growth in a transgenic mouse model of cervical(More)
Designing a binocular-rivalry exhibit for the Exploratorium resulted in the observation of some interesting phenomena. Under conditions of binocular rivalry, motion in the field of one eye can trigger suppression of the other visual field as a whole or in parts. This suppression sometimes occurs only in the area of motion. Subparts of a suppressed area(More)
BACKGROUND Chromatin-associated histone H2AX is a key regulator of the cellular responses to DNA damage. However, non-nucleosomal functions of histone H2AX are poorly characterized. We have recently shown that soluble H2AX can trigger apoptosis but the mechanisms leading to non-chromatin-associated H2AX are unclear. Here, we tested whether stalling of DNA(More)
The purpose of the study was to determine prognostic significance of pretreatment serum levels of different molecules involved in cell to cell interactions along with other clinical parameters in patients with metastatic renal cell carcinoma. sICAM-1, sVCAM-1 and sELAM-1 serum levels were determined by ELISA assays in sera from 99 patients with(More)
Very rapid progression of disease with a median survival of 6-9 months is a common feature of metastatic cutaneous malignant melanoma. Nevertheless, substantial variability of survival suggests that metastatic cutaneous malignant melanoma can be divided into several biological subgroups. Pretreatment serum levels of soluble adhesion molecules and various(More)
Fanconi anemia (FA) is a recessive genome instability syndrome characterized by heightened cellular sensitivity to DNA damage, aplastic anemia and cancer susceptibility. Leukemias and squamous cell carcinomas (SCCs) are the most predominant FA-associated cancers, with the latter exhibiting markedly early disease onset and aggressiveness. Although studies of(More)
The importance of mitochondria as oxygen sensors as well as producers of ATP and reactive oxygen species (ROS) has recently become a focal point of cancer research. However, in the case of melanoma, little information is available to what extent cellular bioenergetics processes contribute to the progression of the disease and related to it, whether(More)
Current reports suggest serum S100 as a prognostic marker for disease progression in advanced malignant melanoma. In this study, we assessed serum levels of S100 and multiple clinical factors in relation to overall survival in 99 patients with metastatic malignant melanoma seen at our institution between May 1990 and April 1996. For statistical analysis, we(More)
