Growth regulatory effects of cyclic AMP and polyamine depletion are dissociable in cultured mouse lymphoma cells. [PDF]

open access: yes, 1983
Treatment of mouse lymphoma S49 cells with D,L-alpha-difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase, depleted cellular polyamine levels and stopped cell growth. The cells were arrested predominantly in G1.

Experimental approaches to understanding the role of protein phosphorylation in the regulation of neuronal function [PDF]

open access: yes, 1983
Studies by Earl Sutherland and his colleagues on hormonal regulation of the breakdown of glycogen in liver resulted in the discovery that the first step in the action of many hormones is to increase the synthesis of cAMP by activating adenylate cyclase ...

Disinhibition of hippocampal CA3 neurons induced by suppression of an adenosine A1 receptor-mediated inhibitory tonus: Pre- and postsynaptic components [PDF]

open access: yes, 1993
Intracellular recordings were performed on hippocampal CA3 neuronsin vitro to investigate the inhibitory tonus generated by endogenously produced adenosine in this brain region.

ABCD of the phosphodiesterase family: interaction and differential activity in COPD

open access: yesInternational Journal of COPD, 2008
David MG HalpinRoyal Devon and Exeter Hospital, Exeter, EX2 5DW, UKAbstract: Phosphodiesterases (PDEs) are important enzymes that hydrolyze the cyclic nucleotides adenosine 3′5′-cyclic monophosphate (cAMP) and guanosine 3′5 ...

Fatty acid oxidation and esterification in isolated rat hepatocytes: regulation by dibutyryl adenosine 3′,5′-cyclic monophosphate

open access: yesJournal of Lipid Research, 1973
Isolated rat hepatocytes rapidly utilized [14C] palmitate and, in particular, synthesized large amounts of neutral lipids from palmitate. Incorporation into cellular lipids occurred at a linear rate proportional to the medium concentration of fatty acids.

Effects of cyclic adenosine 3,5-monophosphate on photoreceptor disc shedding and retinomotor movement. Inhibition of rod shedding and stimulation of cone elongation. [PDF]

open access: yes, 1982
As a test of the hypothesis that cyclic nucleotides play a role in the regulation of retinomotor movements and disc shedding in the photoreceptor-pigment epithelial complex, we have used an in vitro eyecup preparation that sustains both disc shedding and

Galectin-12 in Cellular Differentiation, Apoptosis and Polarization. [PDF]

open access: yes, 2018
Galectin-12 is a member of a family of mammalian lectins characterized by their affinity for β-galactosides and consensus amino acid sequences. The protein structure consists of a single polypeptide chain containing two carbohydrate-recognition domains ...

4-Carbamoylpiperidinium acetate monohydrate

open access: yesActa Crystallographica Section E, 2010
In the structure of the title compound, C6H13N2O+·C2H3O2−·H2O, the amide H atoms of the cations form centrosymmetric cyclic hydrogen-bonding associations incorporating two water molecules [graph set R42(8)], which are conjoint

Targets for the MalI repressor at the divergent Escherichia coliK-12malX-malI promoters [PDF]

open access: yes, 2010
Random mutagenesis has been used to identify the target DNA sites for the MalI repressor at the divergent Escherichia coli K-12 malX-malI promoters. The malX promoter is repressed by MalI binding to a DNA site located from position -24 to position -9 ...
