Immunogenic cancer therapies, including radiation and hypomethylating agents, such as 5-azacytidine, rely on tumor cell-intrinsic activation of the RNA receptor RIG-I for their synergism with immune checkpoint inhibitors. Possible ligands are small nuclear (snRNA) endogenous retroviral elements (ERV) leaking from nucleus during programmed cell death.

cyclizine (1-benzhydryl-4-methyl-piperazine, cas 82-92-8, cyc, i), a piperazine derivative, belongs to h1 antihistamine group of drugs that shows such pharmacological properties as anti-inflammatory, anti-allergic and anti-platelet effects, similar to other h1-receptor antagonists. in this study, two new tolyl and cumene derivatives of i (1-ethyl-4-[(p-isopropylphenyl) (p-tolyl) methyl]-piperaz...

The current study showed that potassium K current (I(K)), which is evoked at depolarizing potentials between -30 and +40 mV in cultured hippocampal neurons, was significantly reduced by exposure to the CB1 cannabinoid receptor agonist WIN 55,212-2 (WIN-2). WIN-2 (20-40 nM) produced an average 45% decrease in I(K) amplitude across all voltage steps, which was prevented by SR141716A, the CB1 rece...

Endocannabinoid (eCB) signaling mediates short-term and long-term synaptic depression (LTD) in many brain areas. In the ventral tegmental area (VTA) and striatum, D(2) dopamine receptors cooperate with group I metabotropic glutamate receptors (mGluRs) to induce eCB-mediated LTD of glutamatergic excitatory and GABAergic inhibitory (I-LTD) synaptic transmission. Because D(2) receptors and group I...

There are two types of feline coronaviruses that can be distinguished by serology and sequence analysis. Type I viruses, which are prevalent in the field but are difficult to isolate and propagate in cell culture, and type II viruses, which are less prevalent but replicate well in cell culture. An important determinant of coronavirus infection, in vivo and in cell culture, is the interaction of...

<b><i>Background:</i></b> Injectable glucagon-like peptide-1 receptor agonists (GLP-1RAs) are proven to be well tolerated and efficacious in people with type 2 diabetes mellitus (T2DM) fasting during Ramadan. The first oral GLP-1RA semaglutide, also indicated for the treatment of T2DM, has specific dosing instructions optimize exposure, which may need altered Ramadan ens...

The Crk proto-oncogene product is an SH2 and SH3 domain-containing adaptor protein. We have previously demonstrated that Crk-II becomes rapidly tyrosine-phosphorylated in response to stimulation with insulin-like growth factor I (IGF-I) and might be involved in the IGF-I receptor signalling pathway. To determine whether this involvement includes the direct interaction of Crk-II with the cytopla...
