The BimEL tumor suppressor is a potent proapoptotic BH3-only protein. We found that, in response to survival signals, BimEL was rapidly phosphorylated on three serine residues in a conserved degron, facilitating binding and degradation via the F box protein betaTrCP. Phosphorylation of the BimEL degron was executed by Rsk1/2 and promoted by the(More)
MOTIVATION Recent years' exponential increase in DNA microarrays experiments has motivated the development of many signal quantitation (SQ) algorithms. These algorithms perform various transformations on the actual measurements aimed to enable researchers to compare readings of different genes quantitatively within one experiment and across separate(More)
RNA interference (RNAi) techniques hold forth great promise for therapeutic silencing of deleterious genes. However, clinical applications of RNAi require the development of safe and efficient methods for intracellular delivery of small interfering RNA (siRNA) oligonucleotides specific to targeted genes. We describe the use of a lipitoid, a cationic(More)
Alterations in genomic content and changes in gene expression levels are central characteristics of tumors and pivotal to the tumorigenic process. We analyzed 23 non-small cell lung cancer (NSCLC) tumors by array comparative genomic hybridization (array CGH). Aberrant regions identified included well-characterized chromosomal aberrations such as(More)
Genomic instabilities, amplifications, deletions and translocations are often observed in tumor cells. In the process of cancer pathogenesis cells acquire multiple genomic alterations, some of which drive the process by triggering overexpression of oncogenes and by silencing tumor suppressors and DNA repair genes. We present data analysis methods designed(More)
Skp2 is an oncoprotein that mediates the degradation of several negative regulators of the cell cycle to promote cell proliferation. A recent report by Huang and colleagues reveals that Skp2 directs the ubiquitylation and subsequent degradation of FoxO1, a member of the FoxO family of transcription factors. Since FoxO proteins possess tumor suppressor(More)
OBJECTIVE In patients who cannot or will not cooperate in behavioral hearing assessment, electrophysiological examinations are used, but are time-consuming because the subject has to remain immobile. The aim of this study was to assess whether auditory steady-state responses (ASSR) are sufficiently reliable, compared to auditory brainstem responses (ABR)(More)
Training of Dental Auxiliaries in the United States Air Force is a highly structured process combining training in short formal courses at the School of Health Care Sciences with extended periods of formal on-the-job training and self-study correspondence courses conducted at bases throughout the Air Force. The rigid control imposed by Air Force training(More)
