Polyclonal antibodies against specific carboxy-terminal sequences of known alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) receptor subunits (GluR-4) were used to screen regional homogenates and subcellular fractions from rat brain. Affinity purified anti-GluR1 (against amino acids 877-899), anti-GluR2/3 (850-862), and anti-GluR4a and(More)
Recent evidence supports the hypothesis that cancer stem cells are responsible for tumour initiation and formation. Using flow cytometry, we isolated a population of CD44+CD24(-) prostate cells that display stem cell characteristics as well as gene expression patterns that predict overall survival in prostate cancer patients. CD44+CD24(-) cells form(More)
Aberrantly activated signal transducer and activator of transcription 3 (Stat3) is implicated in the development of various human cancers. Y705 phosphorylation is conventionally thought to be required for Stat3 signal-dependent activation and seems to play an essential role in some malignancies. Recently, it was shown that Stat3 is activated through novel(More)
The cysteine protease calpain is activated by calcium and has a wide range of substrates. Calpain-mediated cellular damage is associated with many neuropathologies, and calpain also plays a role in signal transduction events that are essential for cell maintenance, including the activation of important kinases and transcription factors. In the present(More)
The postsynaptic molecule gephyrin is involved in clustering neurotransmitter receptors. To test for protein variants that correspond to alternatively spliced gephyrin mRNAs, antibodies were made against 1) an amino-terminal domain of gephyrin (GN(N)) and 2) its invariant carboxy-terminus (GN(C)). Both antibodies recognized an antigen with the expected(More)
