Temporal lobe epilepsy is a common form of drug-resistant epilepsy that sometimes responds to dietary manipulation such as the 'ketogenic diet'. Here we have investigated the effects of the glycolytic inhibitor 2-deoxy-D-glucose (2DG) in the rat kindling model of temporal lobe epilepsy. We show that 2DG potently reduces the progression of kindling and(More)
Negative regulation of transcription is an important strategy in establishing and maintaining cell-specific gene expression patterns. Many neuronal genes are subject to active transcriptional repression outside the nervous system to establish neuronal specificity. NRSF/REST has been demonstrated to regulate at least 30 genes and contribute to their neuronal(More)
mRNA extraction from soil and quantitation by competitive reverse transcription-PCR were combined to study the expression of three manganese peroxidase (MnP) genes during removal of polycyclic aromatic hydrocarbons from cultures of Phanerochaete chrysosporium grown in presterilized soil. Periods of high mnp transcript levels and extractable MnP enzyme(More)
A red-shifted, mutated form of the jelly-fish green fluorescent protein (GFP) under control of a TEF promoter was expressed at high levels in the filamentous fungus Aureobasidium pullulans. In the three transformants studied, all morphotypes of the fungus, including pigmented chlamydospores, expressed GFP and fluoresced brightly. Confocal microscopy showed(More)
The function of the tumor suppressor RE1 silencing transcription factor (REST) is lost in colon and small cell lung cancers and is known to induce anchorage-independent growth in human mammary epithelial cells. However, nothing is currently known about the role of this tumor suppressor in breast cancer. Here, we test the hypothesis that loss of REST(More)
mRNA extraction from soil and quantitation by competitive reverse transcription-PCR were combined to study the expression of the 10 known lignin peroxidase (lip) genes in anthracene-transforming soil cultures of Phanerochaete chrysosporium. Levels of extractable lipA transcript and protein (LiP H8) were well correlated, although they were separated by a(More)
Thorough analysis of fungi in complex substrates has been hampered by inadequate experimental tools for assessing physiological activity and estimating biomass. We report a method for the quantitative assessment of specific fungal mRNAs in soil. The method was applied to complex gene families of Phanerochaete chrysosporium, a white-rot fungus widely used in(More)
In many applications, it is useful to know the sense and amount of viral RNAs present in a sample. In theory, sense-specific measurement of viral RNAs may be achieved by reverse transcription polymerase chain reaction (RT-PCR) assays which utilize primers of defined polarity during the RT step. However, in practice, it has been shown that such assays are(More)
The transcription factor RE1 silencing transcription factor (REST) is lost in approximately 20% of breast cancers. Although it is known that these RESTless tumors are highly aggressive and include all tumor subtypes, the underlying tumorigenic mechanisms remain unknown. In this study, we show that loss of REST results in upregulation of LIN28A, a known(More)
Loss of repressor element 1 silencing transcription factor (REST) occurs in 20% of breast cancers and correlates with a poor patient prognosis. However, the molecular basis for enhanced malignancy in tumors lacking REST (RESTless) is only partially understood. We used multiplatform array data from the Cancer Genome Atlas to identify consistent changes in(More)
