Proper organization of microtubule arrays is essential for intracellular trafficking and cell motility. It is generally assumed that most if not all microtubules in vertebrate somatic cells are formed by the centrosome. Here we demonstrate that a large number of microtubules in untreated human cells originate from the Golgi apparatus in a(More)
A systematic analysis of data generated in key in vitro assays within GSK has been undertaken to identify what impact a range of common substituents have on a range of ADMET parameters. These include; P450 1A2, 2C9, 2C19, 2D6 and 3A4 inhibition, hERG inhibition, phosphate buffer solubility and artificial membrane permeability. We do this by identifying all(More)
The development of natural Foxp3(+) CD4 regulatory T cells (nTregs) proceeds via two steps that involve the initial antigen dependent generation of CD25(+)GITR(hi)Foxp3(-)CD4(+) nTreg precursors followed by the cytokine induction of Foxp3. Using mutant mouse models that lack c-Rel, the critical NF-κB transcription factor required for nTreg differentiation,(More)
BACKGROUND Surrogate endpoints for prostate cancer-specific mortality after curative primary treatment are not well established. We sought to assess time to biochemical failure (TTBF) and prostate-specific antigen doubling time (PSADT) after failure of curative treatment as candidates for this endpoint. METHODS PSA and survival data from the Trans-Tasman(More)
BACKGROUND The value of pretreatment (initial) prostate-specific antigen (iPSA) and biochemical recurrence (BR) as prognostic factors for survival remains unclear. The authors sought to determine why using randomized trial data with 7-year minimum follow-up. METHODS In the Trans-Tasman Radiation Oncology Group 96.01 trial, 802 men with T2b, T2c, T3, or T4(More)
The Saccharomyces cerevisiae inositol polyphosphate 5-phosphatases (Inp51p, Inp52p, and Inp53p) each contain an N-terminal Sac1 domain, followed by a 5-phosphatase domain and a C-terminal proline-rich domain. Disruption of any two of these 5-phosphatases results in abnormal vacuolar and plasma membrane morphology. We have cloned and characterized the(More)
PURPOSE We sought to determine whether short-term neoadjuvant androgen deprivation (STAD) duration influences the optimal time point from which Phoenix fail (time to biochemical failure; TTBF) should be measured. METHODS AND MATERIALS In the Trans-Tasman Radiation Oncology Group 96.01 trial, men with locally advanced prostate cancer were randomized to 3(More)
PURPOSE We studied prostate-specific antigen (PSA) changes after radiation with or without neoadjuvant androgen deprivation to determine posttreatment PSA scenarios in which false-positive biochemical failures (FPBF) are most likely to occur. METHODS AND MATERIALS In the Trans-Tasman Radiation Oncology 96.01 Group trial, patients with T2b, 2c, 3, 4 N0(More)
CD317/tetherin (aka BST2 or HM1.24 antigen) is an interferon inducible membrane protein present in regions of the lipid bilayer enriched in sphingolipids and cholesterol (often termed lipid rafts). It has been implicated in an eclectic mix of cellular processes including, most notably, the retention of fully formed viral particles at the surface of cells(More)
