  In this report, we introduce a new method for identifying aminopeptidases. Because single substrates can be insufficient for enzyme identification, we used an entire library of substrates to obtain more information about enzyme activity and to directly detect aminopeptidases. Moreover, substrates ca

  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  Research perspective In vitro and in vivo studies have demonstrated that increased LPA/ATX signaling contributes to cancer initiation and progression. Recent findings on the role of non-tumoral ATX in cancer progression and metastasis highlighted a new functional contribution for the microenviron

  Studies in zebrafish: vascular and neural development and the regulation of left–right asymmetry Zebrafish embryos represent an excellent model system to examine vertebrate vascular development. Major advantages of the zebrafish system include its genetic tractability, small size, external fertil

  Accumulating data suggest that ROS trigger autophagy but, in turn, autophagy reduces ROS levels [23]. Our results are in agreement because 27-OH mediated autophagy induction interms of LC3 II formation and Beclin 1 protein expression was suppressed by treating the promonocytic cells with the antioxi

  Resection of DNA ends The highly conserved MRN/MRX complex (Mre11-Rad50-Nbs1 in metazoan; Mre11-Rad50-Xrs2 in yeast) and the Ku70/Ku80 heterodimer (hereafter referred to as Ku) are the first protein complexes to be recruited at DSBs [6]. The presence of Ku and MRN/MRX mediates the recruitment of

  According to the KN-93 receptor in molecular skeletons, aromatase inhibitors can be categorized into two types: steroidal and non-steroidal blockers [6]. Steroidal AI (e.g., exemestane in Fig. 1) derived from the substrate androstenedione interacts with aromatase through chemical actions, resulting

  Limitations of this study include the use of HL-1 cardiomyocytes, which show different characteristics than primary cardiomyocytes [56]. Furthermore, sustained TAC in Ampkα1-deficient mice did not favorably influence cardiac function [33]. It must be kept in mind that global Ampkα1-deficiency may af

  Reactive oxygen species is an aspect of oxidative stress which are associated with many diseases such as rheumatoid arthritis, diabetes, inflammation, atherosclerosis and cancers (Collins, 2005; Halliwell, 1994). Thus, the need for naturally occurring antioxidants is of crucial importance. Some biop

  Numerous studies have shown that ω-3 PUFA incorporation into the lipid raft can affect the distribution and function of protein in the lipid raft by altering raft composition [25], [26], [27]. For example, DHA treatment excluded phospholipase D (PLD) from lipid raft toward non-lipid raft, resulting

  Conclusion Twenty compounds with 3,5-dinitrobenzoate scaffold were synthesized and evaluated using cell-free and HWB assays for their 5-LOX inhibition activities. Compared to the parent compound, six compounds show significantly increased enzyme inhibition activities. The best compound, 3-tolyl 3,5

  Finasteride (13) was the first steroidal 5α-reductase inhibitor approved by the US Food and Drug Administration (FDA) in 1992 for treatment of BPH. In fact, long term clinical studies with this drug demonstrated a sustained reduction of the prostatic specific antigen and an overall improvement in BH

  Identification of the kinase that phosphorylates P450c17 The first Ser/Thr kinase that phosphorylates P450c17 was identified only recently. Of the 518 kinases in the human ‘kinome’ 278 are Ser/Thr kinases (Manning et al., 2002), but microarrays identified only 145 Ser/Thr kinases in human NCI-H29

  Additionally, in a previous transgenic model with autotaxin under the control of the MMTV-LTR promoter, aberrant expression of human autotaxin caused late-onset, metastatic breast cancer [5]. The AT-ATX transgenic model is analogous to the previous one because ∼30% of all spontaneous tumors appeared
