  Of the many different types of DNA lesions, DNA double strand breaks (DSBs) are amongst the most deleterious. It has been suggested that a single unrepaired DSB may be sufficient to induce cell death (Bennett et al., 1993), whereas misrepaired DSBs can result in loss of genetic information, potentia

  Although the gene that encodes DHFR has been strongly conserved during evolution, subtle differences in the active sites of bacterial, human and parasite pitavastatin have been exploited to develop DHFR inhibitors specific to particular pathogens 1, 3. For example, pyrimethamine and cycloguanil bind

  While we chose to divide our etiologies into three categories, it should be noted that such division has certain limitations. Even though URIs and the common cold are considered mainly viral in origin and rhinosinusitis mainly bacterial in origin,26, 27 there is considerable overlap between these co

  Dose–Response Studies Against Puromycin–Sensitive Aminopeptidase (PSA). PSA is a ubiquitous metallopeptidase encoded by the NPEPPS gene with subcellular distribution in the cytosol and nucleus [49]. Comprising of a 919 amino 1 98 sale sequence, it has a broad substrate specificity, and is responsib

  Table 3 reports the results for the categorical coding of diagnosis. The categorical coding is less hypothesis driven than the continuous coding because it allows for nonlinear interactions that are driven by only two groups (CN → MCI stable, CN → MCI progressor, and CN → AD). That said, this analys

  2023-10-19

  

  Aldose reductase (ALR2, EC1.1.1.21), the first enzyme in the polyol pathway, is a monomeric oxidoreductase that catalyses the NADPH-dependent reduction of a wide variety of carbonyl compounds, especially glucose. In this metabolism pathway, glucose is firstly reduced to sorbitol catalyzed by ALR2 wi

  2023-10-19

  

  The aldehyde reductase (AKR1A1) and aldose reductase (AKR1B1) belong to aldo-ketoreductase (AKR) superfamily catalyzing the reduction of corresponding aldehydes and ketones involved. Both the closely related enzymes AKR1A1 and AKR1B1 have 65% structural similarity and differ only at the active site.

  Theoretical mechanism of ABCA2 activity in LE/LY in modulation of cholesterol trafficking It is important to confirm that ABCA2 is a lipid transporter and identify the substrates that are mechanistic in its cholesterol sequestering activity. We hypothesize that ABCA2 modulates cholesterol sequest

  6-hydroxydopamine (6-OHDA) is a selective catecholaminergic neurotoxin mainly used to generate lesions in the nigrostriatal pathway in rats (Ungerstedt, 1968). The most common use of 6-OHDA is via unilateral injection into the rat medial forebrain bundle (MFB). DA depletion, nigral DA cell loss, and

  Our findings establish a critical link between HemAC-Lm dimeric structure and cAMP synthesis that helps in explaining how globin-A domain influences AC domain. The following possible homodimeric structure of wild type full length HemAC-Lm has been proposed to explain the role of this globin-A domain

  Pioneering studies on the immunomodulatory role of adenosine date back to the early ‘70 s of last century (Fig. 1), when the critical role of this nucleoside in shaping the development and the activity of several immune cell populations was first established [[18], [19], [20], [21], [22]]. This then

  2023-10-19

  

  Adenosine receptors activate a number of signalling pathways involved in tissue survival including several mitogen-activated protein kinases (Fredholm et al., 2001). The common feature of all adenosine receptors is the positive coupling to ERK1/2, whilst A2B and A3 receptors can also activate the st

  2023-10-19

  

  Some alterations in the integrity of cell membranes caused by toxic agents can be determined by measuring certain enzymes released by damaged cells [8]. The cholinesterases, for example, catalyze the hydrolysis of JW 55 (ACh) in choline and acetic acid. Theses enzymes are divided into two types: th

  Introduction Adenosine deaminase (ADA), also known as adenosine aminohydrolase, is a key enzyme involved in the purine metabolism that converts adenosine to inosine irreversibly (Lupidi et al., 1997). It is a zinc containing metalloenzyme present in both prokaryotes and eukaryotes. In humans ADA

  Epithelial-mesenchymal transition (EMT) is the process by which epithelial cells are trans-differentiated into motile mesenchymal cells. During EMT, epithelial cells reorganize their cortical Pefloxacin cytoskeleton, lose their junctions and apical-basal polarity, change cell shape, and reprogram g
