  Primases are classified into two major groups: first, the DnaG primases, found in bacteria and bacteriophages, and second, the archaeoeukaryotic primases. Remarkably, bacterial and archaeoeukaryotic primases have no structural similarity and, presumably, evolved independently (Leipe et al., 1999). T

  Experiments and Methods Results and Discussion Conclusions Here, the interactions between two newly-synthesized carbazole derivative—cationic δ,δ′‑diazacarbazoles and DNA were characterized by several spectroscopic means, including UV–Vis and fluorescence, AFM and fluorescence imaging. The

  P. falciparum DHFR-TS is a particularly important enzyme, because it is from the protozoan species that is associated with most malaria infections. Since this enzyme is responsible for catalyzing sequential reactions in the thymidylate cycle, its inhibition slows malarial dTMP production and therefo

  Introduction Collagen deposition is a common feature found in cancerous tissues and fibrotic organs/lesions. It is now well accepted that collagen deposition is not just a consequence of disease, but that it can also trigger a vicious cycle. Both chemical and physical signals elicited from collagen

  2019-07-19

  

  Data from our in vitro studies using BEAS-2B cells showed a biphasic response of cells to NNK. The initial phase of decrease in CRM1 expression in NNK-exposed cells was observed in our previous study. In this study, we further showed that p-p53 (Thr55) expression was also decreased during this initi

  Materials and methods Results Artemis has been reported to possess 5′–3′ exonuclease activity in vitro on ssDNA, as well as DNA-PK-dependent endonuclease activity on single-strand overhang and hairpin DNA structures [11]. However, enzymes within the metallo-β-lactamase family typically contain

  To examine the influence of aromatic motifs on the bridging lysine esters we analysed DNA alkylating activity of the set of compounds 1–6. The lysine derivatives were chosen as it is relatively easy to prepare different esters and thereby study the impact of different groups on the reactivity toward

  The aniline R2 group was extensively explored and a large variety of substitution was tolerated at several positions on the aryl ring (). Notably, substitution at the 3-position often gave increased potency. Increasing lipophilic bulk at this position gave increasing potency within an ether series (

  Consistent with prior reports, this study also found the level of 11 cytokines (MIF, IL-1Ra, CTACK, M-CSF, Basic FGF, VCAM-1, SDF-1α, IL-8, IL-16, PDGF-β, and GRO-α) significantly decreased in the sera of adult HFMD patients in comparison with controls. MIF is a pro-inflammaory cytokine that is asso

  The levels of circulating pro-inflammatory cytokines are markedly elevated in ESRD, and have been speculated to play an important role as causative factors in a number of uremic complications [37]. The impairment of phagocyte functions and deregulated cytokine productions are highly prevalent in CRF

  Results Discussion Drug resistance poses the greatest hurdle of achieving high efficacy with AADs in cancer patients. AAD-treated cancer patients often encounter intrinsic and evasive drug resistance that diminishes the therapeutic efficacy to only minor survival benefits in most cancer types.

  A more refined picture of cholinesterase activity patterns may be obtained by measuring ChE activity of the same sample before and after addition of certain cholinesterase inhibitors, with differential specificity for different components of total ChE activity, such as BW284c51 (BW1,5-bis-(4-allyldi

  In some pancreatic and non-pancreatic tissues, the chloride and calcium channels are heavily regulated by phosphorylation by protein kinases, such as PKC, cyclic AMP-dependent protein kinase (PKA), PKCaMKII, PI3K and protein tyrosine kinases [7,36,37]. Since the interaction of triterpenes with recep
