Investigation of the anticancer mechanism of monensin via apoptosis-related factors in SH-SY5Y neuroblastoma cells.

Monensin is an ionophore antibiotic that inhibits the growth of cancer cells. The aim of this study was to investigate the apoptosis-mediated anticarcinogenic effects of monensin in SH-SY5Y neuroblastoma cells. The effects of monensin on cell viability, invasion, migration, and colony formation were determined by XTT, matrigel-chamber, wound healing, and colony formation tests, respectively.

Effects of Monensin and Rapamycin Combination Therapy on Tumor Growth and Apoptosis in a Xenograft Mouse Model of Neuroblastoma.

Neuroblastoma is the most common pediatric solid tumor originating from the neural crest. New treatment options are needed to improve treatment outcomes and the survival of patients with neuroblastoma. Monensin is an ionophore antibiotic with antiparasitic, antibacterial, and anticancer properties isolated from .

Investigation of the TLR4 and IRF3 signaling pathway-mediated effects of monensin in colorectal cancer cells.

Monensin is an ionophore antibiotic isolated from Streptomyces cinnamonensis with very strong antibacterial and antiparasitic effects. Although monensin is known to exhibit anticancer activity in different cancer types, there are a very limited number of studies on its anti-inflammatory effects in colorectal cancer (CRC) cells. The aim of this study was to investigate the TLR4/IRF3-mediated antiproliferative and anti-inflammatory effects of monensin in colorectal cancer cells.

Monensin, an Antibiotic Isolated from , Regulates Human Neuroblastoma Cell Proliferation via the PI3K/AKT Signaling Pathway and Acts Synergistically with Rapamycin.

Neuroblastoma is the most common extracranial childhood tumor and accounts for approximately 15% of pediatric cancer-related deaths. Further studies are needed to identify potential therapeutic targets for neuroblastoma. Monensin is an ionophore antibiotic obtained from with known antibacterial and antiparasitic effects.

Erianin as a Promising Novel Agent in the Treatment of Neuroblastoma: The Anticancer Effects and Underlying Molecular Mechanisms.

Background: Erianin is an active dibenzyl compound isolated from Dendrobium officinale and Dendrobium chrysotoxum and there are very few studies on molecular mechanisms and drug targets of erianin. In addition, there is no study investigating the anti-cancer effect of erianin on neuroblastoma cells.

Objective: The aim of the study is to investigate the anticancer effect of erianin and the underlying mechanism of this effect on SH-SY5Y cells.

Immunohistochemical Evidence for Glutamatergic Regulation of Nesfatin-1 Neurons in the Rat Hypothalamus.

Nesfatin-1, identified as an anorexigenic peptide, regulates the energy metabolism by suppressing food intake. The majority of nesfatin-1-synthesizing neurons are concentrated in various hypothalamic nuclei, especially in the supraoptic (SON), arcuate (ARC) and paraventricular nuclei (PVN). We tested the hypothesis that the glutamatergic system regulates nesfatin-1 neurons through glutamate receptors.

Glutamatergic Activation of Neuronostatin Neurons in the Periventricular Nucleus of the Hypothalamus.

Neuronostatin, a newly identified anorexigenic peptide, is present in the central nervous system. We tested the hypothesis that neuronostatin neurons are activated by feeding as a peripheral factor and that the glutamatergic system has regulatory influences on neuronostatin neurons. The first set of experiments analyzed the activation of neuronostatin neurons by refeeding as a physiological stimulus and the effectiveness of the glutamatergic system on this physiological stimulation.

Uridine treatment protects against neonatal brain damage and long-term cognitive deficits caused by hyperoxia.

Exposure to excessive oxygen in survivors of preterm birth is one of the factors that underlie the adverse neurological outcome in later life. Various pathological changes including enhanced apoptotic activity, oxidative stress and inflammation as well as decreased neuronal survival has been demonstrated in animal models of neonatal hyperoxia. The aim of the present study was to investigate the effect of administering uridine, an anti-apoptotic agent, on cellular, molecular and behavioral consequences of hyperoxia-induced brain damage in a neonatal rat model.

Long-term cognitive effects of uridine treatment in a neonatal rat model of hypoxic-ischemic encephalopathy.

Hypoxic-ischemic encephalopathy (HIE), is the most common brain disorder in neonates during the perinatal period, which, to date, can only be managed to some extent by hypothermia. Uridine is the principal circulating pyrimidine in humans which is utilized as a precursor for membrane phospholipid biosynthesis. Uridine has recently been shown to provide clinical benefit in treatment of Alzheimer's disease due to its involvement in increasing number of brain synapses along with other phospholipid precursors.

Immunohistochemical localization of ionotropic glutamate receptors in the rat red nucleus.

In this study, we aimed to determine the presence as well as the diverse distribution of N-methyl-D-aspartate (NMDA) and non-NMDA glutamate receptor subunits in the rat red nucleus. Using adult Sprague-Dawley rats as the experimental animals, immunohistochemistry was performed on 30 µm thick coronal brain sections with antibodies against α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (GluA1-4), kainate (GluK1, GluK2/3, and GluK5), and NMDA (GluN1 and GluN2A) receptor subunits. The results showed that all ionotropic glutamate receptor subunits are expressed in the red nucleus.
