  Introduction Prolyl hydroxylation is a widely observed post translational modification in collagen, an abundant animal protein. The high content (~13% per chain of the triple helical structure) of 4-hydroxyproline (Hyp,O) in collagen, togather with the natural abundance of collagen has led to the e

  NF-κB is a family of protein mediators that regulate various innate and adaptive immune responses [29,30]. The NF-κB family consists of the following five proteins: c-Rel (Rel); p65 (RelA); RelB; p50(NF-κB1); and p52(NF-κB2). It has been confirmed that NF-κB is activated by TNF family cytokines, suc

  As mentioned above, EBI2 and its ligand show some similarities to the sphingosine 1-phosphate (S1P)/S1P-receptor system, which mediates T cell egress from lymph nodes. Blockade of this system yielded in the first oral drug for MS patients named fingolimod. Therefore, the hope that EBI2 deficiency wo

  cAMP-mediated signaling pathways are important for maintaining metabolic homeostasis, and the effects of the glucagon/catecholamine–cAMP–PKA axis on energy balance have been well documented [20]. For example, SC 560 sale of the PKA 2β regulatory subunit (RIIβ) in mice leads to increased expression o

  As a support, chitosan presents interesting characteristics that reinforce its great potential for enzyme immobilization [18,19]. Firstly, it is produced from renewable natural sources in addition to being biodegradable and water insoluble [20,21]. Also, the main peculiarity in the chitosan structur

  Ultrasound is an acoustic wave with a frequency >20 kHz that needs a medium to propagate [20]. Accompanied by the spread of an ultrasonic wave, a series of alternating cycles of compression and rarefaction emerge in the liquid medium. During the rarefaction cycle, microbubbles are formed because of

  Introduction Cerebral stroke causes an efflux of various groups of progenitor and stem cells from bone marrow to bloodstream and the levels of these cells correlate with neurological status of stroke patients (Gójska-Grymajło et al., 2012, 2018). It is thought that paracrine factors produced by t

  Introduction Mammalian proteases comprise both the peptidases or exopeptidases, which act at the N- or C-terminal positions of polypeptides, and proteinases or endopeptidases, which are capable of cleaving peptide bonds in the central regions of polypeptides. The endopeptidases are classified in

  The in vitro enantioselective metabolism of pesticides has been investigated by employing human liver microsomes, which are a reliable resource to perform MCL enantioselective risk assessment in humans (Carrão et al., 2019; de Albuquerque et al., 2018, 2016; Yao et al., 2016).

  Multi-subunit RINGs There are RING-type E3s that exist as multi-subunit assemblies (see Fig. 3B). A striking example is the Cullin RING Ligase (CRL) superfamily [35], which exhibits enormous plasticity in substrate specificity. Each CRL subfamily is characterized by a cullin protein (Cul-1, 2, 3,

  Like all other cellular processes, ubiquitination is also tightly regulated; more so, as myriads of pathways are controlled via this conjugation and dysregulation of ubiquitination has been implicated in various diseases including cancer [16], [17]. Quite a few of such regulatory mechanisms that con
