  2024-05-16

  

  In vascular endothelial cells, L-arginine produces nitric oxide (NO) under the action of nitric oxide synthase (NOS), and nitric oxide can activate guanylate cyclase to produce a large amount of cGMP, thereby relaxing vascular smooth muscle and expanding blood vessels. Numerous studies have confirme

  Based on its kinetic parameters and quaternary structure, R. pycnus arginase is a typical ureotelic L-arginase [2]. The Km value of the enzyme was lower than other arginases from other organisms (Table 2), including S. cerevisiae (15.7mM), B. anthracis (10mM), B. caldovelox (3.4mM), human liver (2.3

  Mechanistically, it was soon realized that in undead cells, Dronc promotes the activation of Jun-N-terminal kinase (JNK) signaling as the major inducer of AiP [25], [28] (Fig. 2B,C). However, it has been unknown for a long time how active Dronc promotes JNK signaling. Recently, it was reported that

  The physiologic conditions and signaling mechanisms that regulate apelin secretion and APLNR expression in malignant tissues appear to be multifactorial. Previous studies have shown that hyperplastic and neoplastic cholangiocytes secrete a variety of hormones, peptides, and growth factors that help

  2024-05-16

  

  The zinc transporter proteins are members of the SLC superfamily of metal transporters, and comprise two structurally and functionally different groups, the zinc-importer (ZIP; Zrt-, Irt-like proteins) family (SLC39A), which regulate zinc transport into the cytoplasm from outside the cell and from i

  Role of AMPK in inflammation signaling Pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor-α (TNF-α), activate Ikβ kinase (IKKβ), which phosphorylates IκBα, triggering the degradation of proteasomal IκB. This liberates active nuclear factor kB (NF-kB) to translocate i

  Funding Introduction Plants absorb both inorganic nitrogen (ammonium and nitrate) and organic nitrogen (amino acids and peptides) from the soil [1]. The first organic nitrogenous molecule produced from inorganic nitrogen is Gln, whose terminal amino group is successively transferred to make Gl

  Interest in natural products has led to the study of plant extracts as sources of ARIs. However, chemical complexity of natural extracts makes the identification of ARIs challenging and time-consuming. Identification of bioactive compounds with the desired biological effect from natural products, co

  Two cell-surface trans-membrane receptors have been identified for adiponectin, AdipoR1 and AdipoR2 [21], and adiponectin action is known to signal through these receptors and the docking protein APPL1 [22]. In muscle and liver cells, signal transduction involves the phosphorylation and activation o

  When added to the culture medium, extracellular ATP is metabolized into adenosine by ectonucleotidases, and ARs are then activated by adenosine with concentrations in the micromolar range [27]. However, our study showed that activation of ARs by exogenous adenosine could not induce the odontoblastic

  Acknowledgements Introduction Autoantibodies directed at neurotransmitter receptors and ion channels are pathogenic and/or biomarkers in several autoimmune neurological diseases [1]. For example, autoantibodies directed against voltage-gated potassium channels, the P/Q-type (α1A) voltage-gated
