Screening of AMP- and GMP-producing enzymes such as phosphodiesterases (PDEs), ligases, and synthetases would be simplified by the ability to directly detect unmodified nucleoside monophosphates. To address this need, we developed polyclonal and monoclonal antibodies that recognize AMP and GMP

Chronic inflammation predisposes to aging-associated disease, but it is unknown whether immunity regulation might be important for extending healthy lifespan. Here we show that in C. elegans, dietary restriction (DR) extends lifespan by modulating a conserved innate immunity pathway that is

Guanosine-5'-monophosphate (GMP) was evaluated as a neuroprotective agent against the damage induced by glutamate in rat hippocampal slices submitted to glucose deprivation. In slices maintained under physiological conditions, glutamate (0.01 to 10 mM), Kainate, alpha-amino-3-hydroxi-5-methylisoxazole-propionic acid (AMPA), N-methyl-D-aspartate (NMDA), 1S,3R-aminocyclopentane-1,3-dicarboxylic
Vanessa Conn et al.
RNA (New York, N.Y.), 25(9), 1202-1210 (2019-06-04)
Reverse transcription of RNA is fallible, introducing biases and confounding the quantification of transcript abundance. We demonstrate that circular RNAs (circRNAs) are more subjective to overestimation of transcript abundance than cognate linear RNAs due to their covalently closed, circular form
Tatsuo Yanagisawa et al.
Cell chemical biology, 26(7), 936-949 (2019-04-30)
Pyrrolysyl-tRNA synthetase (PylRS) and tRNAPyl have been extensively used for genetic-code expansion. A Methanosarcina mazei PylRS mutant bearing the Y306A and Y384F mutations (PylRS(Y306A/Y384F)) encodes various bulky non-natural lysine derivatives by UAG. In this study, we examined how PylRS(Y306A/Y384F) recognizes

Overstimulation of the glutamatergic system (excitotoxicity) is involved in various acute and chronic brain diseases. Several studies support the hypothesis that guanosine-5'-monophosphate (GMP) can modulate glutamatergic neurotransmission. The aim of this study was to evaluate the effects of chronically administered
