  HIF-α Signaling in AA Therapy Resistance An important result emerging from Phase 3 clinical trials testing AA therapies is improvement of progression-free survival (PFS) that is not accompanied by enhanced overall survival (OS) [26]. This dichotomy has been attributed to mechanisms of acquired re

  Recent studies have supported the existence of an inward RAS regulatory mechanism in which AT1 receptors downregulate angiotensin-converting enzyme 2 (ACE2) and subsequently impair angiotensin-(1-7) generation and MAS functionality (Jessup et al., 2006, Gallagher et al., 2008, Xia et al., 2009, Pern

  In addition, unconventional mechanisms of internalization cannot be ignored. It is generally believed that the conventional homologous internalization of a GPCR depends on the activation of G proteins, since GRK activation requires the pre-activation of G proteins (Fig. 2). Feng et al. demonstrated

  2024-06-08

  

  In this study, we have generated new FRET reporters to screen all submembrane domains of AT1R for interactions with CaM. We identified a new CaM-binding domain on the receptor’s SMD2 (a.a. 125 – 141), confirmed interactions at SMD4JM (a.a. 309 – 327) and characterized the full interacting domain in

  Detailed analysis of the dose dependence of Aβ effects revealed that at low amounts, Aβ can also act as a positive regulator of presynaptic activity, enhancing the neurotransmitter release probability and increasing the neuronal excitability [2]. The facilitator effects of low Aβ dose on excitatory

  Evidence shows that glial activation increases the expression of cytokines and chemokines in Parkinson's disease, which precede the degeneration of the substance nigra (Halliday and Stevens, 2011, Tansey and Goldberg, 2010). The use of non-steroidal anti-inflammatory drugs (except aspirin) can preve

  2024-06-07

  

  The metabolism of amino acids into volatile aldehydes involves both decarboxylation and deamination steps. The order of these reactions and the enzymes performing the catalysis differ among plants [13]. In tomato fruit the conversion of L-Phe to 2-phenylethanal is catalyzed by two enzymatic steps, i

  2024-06-07

  

  It was also shown that 15% of crizotinib resistance mechanisms can be due to an amplification of ALK gene while 30% are caused by a variety of secondary mutations (S1206Y, G1202R, L1196M, C1156Y, G1269A, L1152R, F1174L and 1151Tins) in ALK tyrosine kinase. These mutations can modify the conformation

  Targeted disruption of the Akt1 gene in mice induces a growth retardation phenotype [4,19]. Akt2 KO mice reveal mild growth retardation and insulin resistance [4,20,21]. Akt1/2 double KO (DKO) mice display severe growth deficiency and die shortly after birth. These mice exhibit impaired bone and ski

  2024-06-07

  

  Interaction between AhR and ligands leads to AhR transformation (Fig. 1), characterized by a rapid receptor nuclear translocation and the formation of AhR/Arnt complex and the release of the chaperone proteins. Following AhR transformation, the AhR/Arnt complex binds to its cognate DNA consensus seq

  It is important to note that stable amnesia is, apparently, a general biological phenomenon and can be found in different animal species. In studies on rats, it was found that if reconsolidation of conditioned olfactory aversion memory was impaired by the antagonist of NMDA glutamate receptors, amne

  We also demonstrate that PACAP treatment dose-dependently disrupts performance in the 5CSRTT, suggestive of attentional deficits, another core feature of mood and anxiety disorders. Treatment with PACAP (.5–1.0 µg) decreased the percentage of correct responses, increased the percentage of trials in

  Introduction Fungi are an inexhaustible source of natural products mainly due to their wide distribution in the nature, estimated to range from 1.5 to 5.1 million species in the world [1]. Secondary metabolites from fungi represent a substantial fraction of drugs and drug models in pharmaceutical

  The hippocampus is the primary brain structure involved in learning and memory. The role of hippocampal synaptic plasticity in neurological processes in cognition and depression has been extensively demonstrated. Synaptophysin is a critical substance in synaptogenesis, which is necessary for learnin
