  2023-07-15

  

  Despite the absence of disulfide bonds in its linear structure, KT43C displays antifungal and antibacterial activity. Disulfide bonds are determinants of defensins' integrity and have been reported to increase the antimicrobial activity (Jenssen et al., 2006). However, some linear derivatives of AMP

  2023-07-15

  

  Epidermal growth factor (EGF) has been shown to increase the 12S-lipoxygenase mRNA level by about two-fold in human epidermoid carcinoma A431 cells [71]. This enzyme was shown to be of the platelet-type and associated with the microsomal fraction of the cells [71], [72]. A requirement for EGF recept

  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

  2023-07-15

  

  The mechanisms that control Ahr transcription are poorly understood, especially when considering cell type-specific regulation. A recent report suggested that the Ahr transcription might be directly promoted by RORγt [retinoic Afuresertib receptor (RAR)-related orphan receptor γt] based on ChIP-Seq

  2023-07-15

  

  In chicken ovary, the adiponectin gene was found to be mainly expressed in theca cells and is suggested to exert a paracrine or autocrine effect on ovarian steroidogenesis (Chabrolle et al., 2007). A limited number of studies have revealed the effect of adiponectin on ovarian steroidogenesis or its

  2023-07-15

  

  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

  Using constant potential amperometry and electrochemical enzyme-based biosensors selective for choline—and, therefore, an accurate readout of resveratrol release (Baker et al., 2015; Bruno et al., 2006a; Parikh et al., 2004, 2007)—tonic and phasic release of acetylcholine were measured simultaneous

  2023-07-15

  

  Regarding the 5-HT1B receptors, they act as terminal receptors and are involved in the presynaptic regulation of the release of 5-HT. But at spinal level these receptors are principally situated post-synaptically (Sari, 2004). The ability of autoreceptors to regulate extracellular levels of 5-HT dur

  Over the past decade, extensive research has been directed toward the discovery of Aurora-selective small-molecule inhibitors. As a result, a handful of Aurora inhibitors has been identified. Among them, 1 (VX-680) and 2 (SNS-314) have entered human clinical trials as pan-Aurora kinase inhibitors (F

  Introduction The vacuolar ATPases (V-ATPases) are ATP-driven proton pumps that play important roles in both normal and disease processes [1], [2], [3], [4], [5]. V-ATPases within cells function in such processes as intracellular membrane traffic, protein processing and degradation, coupled transp

  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

  Hydrogen sulfide (H2S) [33], a colorless and water-soluble gas with the smell of rotten eggs, is now recognized as an important gasotransmitter, after the extensive study of nitric oxide (NO) and carbon monoxide (CO). H2S is produced endogenously via enzymatic reactions of cysteine, homocysteine and

  The transcription factor activator protein-1 (AP-1) is a redox-sensitive transcription factor whose activity is controlled by agents that perturb intracellular thiol concentrations [10,11]. AP-1 is mainly composed of Jun, Fos, and ATF protein dimers [12,13]. AP-1 mediates the regulation of numerous

  It is now thought that tight binding of HMGB to condensed chromatin may not be restricted to apoptotic cells. That HMGB proteins might actually be involved in the organization and/or maintenance of heterochromatic regions is suggested by the results of experiments analyzing the stable binding of the
