  2023-02-07

  

  Our data indicate that the D1 domain only needs to hydrolyze ATP a few times, or perhaps even just once, during the processing of a given substrate molecule, whereas the D2 domain hydrolyzes ATP many times. Consistent with this model, only D2 contains the canonical aromatic pore loop residues implic

  2023-02-07

  

  Tumor suppressor ARF regulates the activity of p53 by inhibiting the functions of Mdm2. ARF is induced by hyperproliferative signals emanating from oncogenic Ras, overexpressed c-myc, and from deregulated E2F . ARF prevents p53 degradation and leads to increased p53 function by sequestering Mdm2 to

  2023-02-07

  

  Antioxidative enzymes such as SOD and CAT play prominent roles in protecting against oxidative stress and extending food freshness due to their ability in scavenging active oxygen species for maintaining cell membrane integrity. Evidence shows that activities of SOD and CAT are positively affected b

  2023-02-07

  

  Two major categories of arginase inhibitors have been distinguished (Fig. 3): the first category comprises synthetic arginase inhibitors, which have been developed from the substrate l-arginine [35]; and the second category includes inhibitors derived from natural products [36]. The category of synt

  2023-02-07

  

  Weak and transient interactions of HMGB proteins in such hit-and-run mechanisms are understandable given that “fluorescence loss in photobleaching” (FLIP) experiments employing GFP-labeled HMGBs have shown that in living cells they are the most mobile of all nuclear proteins [144]. The entire pool o

  2023-02-07

  

  We provide here direct evidences that AT1 receptors are active in ADSCs since Ang II induces intracellular Ca mobilization in these cells. Data obtained during the observation of Ca influxes led us to the search for the ADSCs subpopulation constantly expressing AT1 receptor. ADSCs are necessary for

  Recent work has detailed the impact of genetic d-glucose of AMPK in the liver, revealing only minor phenotypes upon removal in mice (Boudaba et al., 2018). However, these studies very elegantly showed the potential for small molecule-mediated activation of AMPK to elicit large changes in lipid meta

  2023-02-07

  

  We found that decreased Ng levels lead to a lower threshold for LTD induction at L4–L2/3 synapses. Previous studies in hippocampal slice culture have shown that LTD at individual synapses induces spine elimination at both the targeted synapse and selective neighboring synapses when spines are monito

  2023-02-06

  

  Since the cloning of ARs in the beginning of the 1990s, the efforts to characterize them have led to the accumulation of a substantial amount of experimental data. Decades of site-directed mutagenesis (SDM; Box 1) studies, in combination with pharmacological data and computational modeling, have pav

  It is well known that the thymus plays an important function in the complex pathogenesis and perpetuation of MG. We compared resistin levels between patients with MG with or without thymoma and found that those with thymoma had higher levels than those without thymoma. It has been previously recogni

  In the present study, the alternative splicing of several nAChR subunits was identified in the oriental migratory locust (Locusta migratoria manilensis Meyen), a serious worldwide pest to agricultural production and also a model insect species [5]. Several α subunits were tried to co-express with ra

  Another important question concerns the mechanism by which a polyubiquitinated substrate is released from the Cdc48 complex and passed on to downstream components, such as the proteasome. There are at least three proposed models. In the first, a ubiquitinated substrate is transferred by ubiquitin-bi

  Secondly, leptin has been shown to enhance aromatase mRNA expression, aromatase content and its enzymatic activity in epithelial breast cancer Curcumin by inducing promoters II and I.3 via an enhanced binding of transcription activator protein 1 (AP-1) complex to specific DNA sites in the promoter

  AP-1 activity is increased by MAP kinase stimulation in different cell types (Whitmarsh and Davis, 1996), while MKP-1, the enzyme that catalyzes the dephosphorylation and inactivation of MAP kinases in the nucleus, inhibits AP-1 (Rössler et al., 2008, Rössler and Thiel, 2009, Mayer et al., 2011, Thi
