Accumulating lines of evidence suggest a possibility that glycine is useful as an immuno-modulating amino acid. Glycine most likely prevents the lipopolysaccharide (LPS)-induced elevation of intracellular Ca(2+) concentration in Kupffer cells, thereby minimizing LPS receptor signaling and cytokine

The anti-tumor effects of alkaloids from the seeds of Strychnos nux-vomica on HepG2 cells and its possible mechanism.

To screen the anti-tumor effects of the four alkaloids: brucine, strychnine, brucine N-oxide and isostrychnine from the seed of Strychnos nux-vomica, MTT assay was used to examine the growth inhibitory effects of these alkaloids on human hepatoma cell line (HepG2). Brucine, strychnine and

Strychnine inhibits inflammatory angiogenesis in mice via down regulation of VEGF, TNF-α and TGF-β.

BACKGROUND Recent studies have revealed the antinociceptive effects of glycine transporter (GlyT) inhibitors in neuropathic pain models such as sciatic nerve-injured and diabetic animals. Bone cancer can cause the most severe pain according to complex mechanisms in which a neuropathic element is

Brucine and Strychnine are alkaloids isolated from the seeds of Strychnos nux vomica L., which have long been used as a traditional medicine for the treatment of tumor. However, the effect of Brucine and Strychnine on colorectal cancer (CRC) and the underlying molecular mechanism remain unclear. In

Neo-angiogenesis is important for tumor growth. Glycine is a non-toxic amino acid with suspected anti-angiogenic effects. This study was designed to evaluate anti-angiogenic effects of glycine in colorectal cancer. Glycine was added to cultures of human and rat colorectal cancer cells (CRC), and

Taurine blunts LPS-induced increases in intracellular calcium and TNF-alpha production by Kupffer cells.

Activation of Kupffer cells by lipopolysaccharide (LPS) plays a pivotal role in the onset of pathophysiological events that occur during endotoxemia and intracellular calcium ([Ca2+]i) is involved in LPS-stimulated cytokine production. Recently, it was shown that Kupffer cells contain a

In rats with chronically implanted intrathecal catheters, high concentrations of morphine (3 microliters of 50 mg/ml: 150 micrograms) yielded a reliable and striking syndrome of pain behavior that involved intermittent bouts of biting and scratching at the dermatomes innervated by levels of the

Endothelial cells contain a glycine-gated chloride channel.

Glycine inhibited growth of B16 melanoma tumors in vivo most likely because of the inhibition of angiogenesis. Here, the hypothesis that the anticancer effect of glycine in vivo is due to expression of a glycine-gated Cl- channel in endothelial cells was tested. First, the effects of glycine on

Multiple myeloma (MM) is an incurable B cell neoplasm causing significant morbidity and mortality. Despite recent advances in the MM-treatment, the disease still remains incurable; necessitating a search for new therapeutic agents. Therefore, Strychnos nux-vomica L. root extract (SN) was screened

Activated glycine receptors may decrease endosomal NADPH oxidase activity by opposing ClC-3-mediated efflux of chloride from endosomes.

Prisijungti Registracija

Receptor-mediated activation of NADPH oxidase complexes commonly occurs in endosomes; the hydrogen peroxide produced by the dismutation of superoxide generated within the endosomes often functions to boost receptor function by reversibly inhibiting protein tyrosine phosphatases or by promoting

The historic role of plants in healing declined early in the twentieth century with the ascendency of synthetic drugs, even though a number of basic medical tools, such as opium, strychnine, and cocaine, are of botanical origin. In recent years, interest in natural products has been restored

Glycine inhibits the LPS-induced increase in cytosolic Ca2+ concentration and TNFalpha production in cardiomyocytes by activating a glycine receptor.

OBJECTIVE Previous studies have demonstrated that glycine (GLY) markedly reduces lipopolysaccharide (LPS)-induced myocardial injury.However, the mechanism of this effect is still unclear. The present study investigated the effect of GLY on cytosolic calcium concentration([Ca2+]c) and tumor necrosis
