  2025-01-18

  

  Aromatase: the key enzyme for estrogen formation in adipose tissue Estrogens are synthesized from androgens by aromatase, a member of the cytochrome P450 superfamily, which is the rate-limiting enzyme in estrogen biosynthesis (Santen et al, 2009, Simpson et al, 1994). At the cellular level, aroma

  Introduction Cytochrome P450 19 (CYP19; aromatase) catalyzes the conversion of androgens to estrogens in a three-reaction sequence, where each step depends on NADPH and O2 [[1], [2], [3]]. The first two steps are accepted to be hydroxylations of the steroid C19 methyl group, whereas the final step

  2025-01-18

  

  Similar to other MADS box proteins, MEF2 factors associate with a variety of transcriptional cofactors to control specific sets of downstream target genes. Some of the cofactors such as MyoD, GATA4, NFAT, TH receptor, p300, 14.3.3 and ERK5 stimulate MEF2 activity, whereas others, such as HDACs4-5-7-

  Many naphthoquinone derivatives have been previously obtained from fungi in the genus Fusarium isolated from various sources, F. oxysporum from the root of citrus (Nagia and El-Mohamedy, 2007), Fusarium sp. (No. b77) from the mangrove plant (Shao et al., 2010), F. solani and F. oxysporum from fibrou

  Antiangiogenic therapy in non-small cell lung cancer (NSCLC) Antiangiogenic targeted therapy is an area of active research in which numerous agents have been studied and have been shown to be effective for many tumor types including NSCLC. Angiogenesis is frequently upregulated in malignant solid

  We provide here direct evidences that AT1 receptors are active in ADSCs since Ang II induces intracellular Ca mobilization in these cells. Data obtained during the observation of Ca influxes led us to the search for the ADSCs subpopulation constantly expressing AT1 receptor. ADSCs are necessary for

  Conclusions Our study confirms that N-terminal mutations can affect Aβ fibril and oligomer formation, despite lying outside the core amyloid region of Aβ. Of the three factors that may influence Aβ-mediated toxicity (primary structure of Aβ, assembly structure and cellular responses), our results

  2025-01-18

  

  We found that decreased Ng levels lead to a lower threshold for LTD induction at L4–L2/3 synapses. Previous studies in hippocampal slice culture have shown that LTD at individual synapses induces spine elimination at both the targeted synapse and selective neighboring synapses when spines are monito

  2025-01-17

  

  Most of the identified aldose reductase inhibitors possess undesirable effects like poor pharmacokinetic properties, hypersensitivity and Steven-Johnson Syndrome [1]. However, the main side effect is the lack of selectivity relative to aldehyde reductase (ALR1, EC 1.1.1.2). ALR1 plays the important

  Interestingly, intermittent high doses of AKT inhibitors have been shown to be a more effective strategy both clinically and pre-clinically. High doses appear to be required for induction of apoptosis and intermittent schedules overcome the low therapeutic index of these compounds. This is particula

  2025-01-17

  

  The decreased βAR-mediated response has been attributed to different mechanisms, including an attenuation of PKA activation, an impaired generation of cyclic AMP, a reduced receptor density, and a less efficient coupling to adenylyl-cyclase [10]. However, currently there is no single molecular or ce

  Role of OCT3 in histamine clearance Histamine is a powerful neuromodulator, as well as a regulator of immune processes and vascular tone in the central nervous system (Gross, 1981; Haas et al., 2008; Jutel et al., 2006). In contrast to 5-HT and the catecholamines, a high-affinity transporter for

  Our co-IP data show that 5HT1A or 5HT2A receptors do not heterodimerize with mGluR1α receptors. Given that both 5-HT and mGlu receptors are GPCRs and produce anxiolytic effects, a degree of cooperativity via a functional cross-talk may still exist between these receptors [11]. In addition to the fun

  The srd5a isoforms showed unique expression profiles in early FHM development (Fig. 2). Similar to amphibian embryos, there was a high abundance of both srd5a1 and srd5a3 at 1dpf in FHMs, suggesting that mRNA for these enzymes may be maternally deposited and that these enzymes may play a key role in
