The functional and therapeutic importance of the Warburg effect is increasingly recognized, and glycolysis has become a target of anticancer strategies. We recently reported the identification of a group of novel small compounds that inhibit basal glucose transport and reduce cancer cell growth by a glucose deprivation-like mechanism. We hypothesized that(More)
Mitotane is an important adrenalytic drug for the treatment of adrenal cancer whose use is limited by toxicity. Reports from another laboratory indicated that a methylated homolog of Mitotane (Mitometh) tested in guinea pigs possessed comparable adrenalytic activity but was less toxic than Mitotane. This observation prompted us to undertake a comparative(More)
Expression of many aminoacyl-tRNA synthetase, amino acid biosynthesis and transport genes in Bacillus subtilis is controlled at the level of transcription termination using the T box system and requires the formation of specific secondary structures in the mRNA leader region. One structure functions as a transcriptional terminator, while an alternate form,(More)
A unique RNA-RNA interaction occurs between uncharged tRNA and the untranslated mRNA leader region of bacterial T box genes. The interaction results in activation of a transcriptional antitermination molecular switch (riboswitch) by stabilizing an antiterminator RNA element and precluding formation of a competing transcriptional terminator RNA element. The(More)
Most urethral diverticula should be diagnosed on clinical grounds alone, but investigations may be used to confirm the diagnosis in difficult cases, delineate the extent of the disease and investigate other entities such as stress incontinence. A high index of suspicion is required when assessing women with lower urinary tract symptoms to ensure that cases(More)
The solution conformation of an RNA pseudoknot, which is a mutant of the pseudoknot required for ribosomal frameshifting in mouse mammary tumor virus, has been determined by NMR. The 32-nucleotide RNA pseudoknot does not promote efficient frameshifting, although its sequence is very similar to the efficient frameshifting pseudoknot whose structure was(More)
The structure-activity relationship of a series of oxazolidinones binding to T-box riboswitch antiterminator RNA has been investigated. Oxazolidinones differentially substituted at C-5 were prepared and the ligand-induced fluorescence resonance energy transfer (FRET) changes in FRET-labeled antiterminator model RNA were assayed. Both qualitative and(More)
OBJECTIVES To assess the long-term outcomes of patients with prostate cancer managed with intermittent androgen suppression (IAS) following their enrollment in an open, non-randomised feasibility study initiated 10 years ago. PATIENTS AND METHODS Patients with prostate cancer who developed marked side effects following androgen deprivation were considered(More)
Ribosomal frameshifting, a translational mechanism used during retroviral replication, involves a directed change in reading frame at a specific site at a defined frequency. Such programmed frameshifting at the mouse mammary tumor virus (MMTV) gag-pro shift site requires two mRNA signals: a heptanucleotide shifty sequence and a pseudoknot structure(More)
The T box transcription antitermination mechanism is found in many Gram-positive bacteria. The T box genes are typically tRNA synthetase, amino acid biosynthesis, and amino acid transport genes that have a common transcriptional control mechanism in which a unique RNA-RNA interaction occurs between an uncharged tRNA and the 5' leader region of the nascent(More)
