2019-11-18
The ribosomal synthesis of D-proteins is not currently feasible; the best effort undertaken so far was limited to the translational incorporation of two D-amino acids into the nascent protein chain by means of modified ribosomes (Dedkova et al., 2006). We therefore apply solid-phase peptide synthesi

We show that direct contact with MSCs is necessary and sufficient to induce DDR2 upregulation in breast cancer cells. DDR2 expression in MSC is required for collagen deposition and leads to increased DDR2 expression and activation in breast cancer cells. This paracrine-autocrine MSC-cancer cell axis

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

Besides degrading cholesterol, the cholesterol degradation pathway also offers a route to obtain useful starting materials for the production of steroid drugs and hormones. Indeed, steroids are among the most marketed pharmaceuticals with about 300 approved steroid drugs [15] and a worldwide market

Materials and methods Results and discussion Iron (II)/2-oxoglutarate (2-OG)-dependent oxygenases [28], [29] catalyze oxidative reactions of a range of metabolic processes including the hydroxylation of l-proline and l-lysine residues during the post-translational modification of collagen. Mor

Estrogens: Definition and history The term “estrogens” refers to a group of female hormones, including estrone, estradiol, estriol, and estretrol (Fig. 1). Chemically, estrogens belong to the family of organic compounds known as steroids. As such, their core structure is composed of 17 carbon-carbo

Considering all these facts, in the present study, we investigated the effects of two highly selective CRF receptor 2 antagonists (antisavaugine-30, ASV-30; and astressin-2B, AST-2B) on anxiety behavior in rats. The rationale for such an experimental approach was based on the premise that fear and s

The small GTPase Ran regulates karyopherin–cargo interactions and the directionality of karyopherin-mediated transport. Like other Ras-family GTPases, Ran cycles between GTP- and GDP-bound states, and the two surface loops in Ran, referred to as the switch I and switch II loops, undergo significant

However, with regard to the involvement of PEP in neoplastic processes, few studies and restricted to a very limited number of different tumors have been carried out [4], [18], [19]. Therefore, in order to ascertain the possible role of this enzyme in pathological proliferative tissues, in the prese

One architecture, termed closed, has been visualized at near-atomic resolution in cryo-EM maps of recombinant complexes that superimpose with earlier lower-resolution EM data obtained for APC/CCDC20–MCC purified from HeLa BDA-366 arrested during the mitotic checkpoint (Figure 4E) 38, 48, 51. Here, M

WES and validation by Sanger sequencing in PNGS-252 revealed an apparent homozygous c.4C>G missense alteration (GenBank: NM_014176.3), resulting in the amino Aminoallyl-dUTP receptor substitution p.Gln2Glu (Figure 1A). This mutation must be very rare, because this is not listed in the NHLBI Exome Se

Besides being the only enzyme, E1 is also the largest and arguably most complex protein encoded by papillomaviruses. As the replicative helicase, E1 plays a central role in the viral life cycle. To do so, E1 engages in multiple protein–protein and protein–nucleic 5-Methyl-CTP interactions to create
