2023-11-28

MicroRNA (miRNA) is an abundant group of small (22-nucleotide) noncoding RNA molecules that directly binds with 3′ untranslated region (UTR) of target messenger RNAs (mRNAs) to regulate gene expression, playing an important role in variety of biological processes including cell proliferation, apopto

2023-11-28

Additionally, regulation of GPCR heteromerization by specific ligands may depend not only on the affinity of ligands for receptors, but also on presence of different interacting proteins co-localizing with the receptors in the specific cell, which may induce some conformational changes and contribut

2023-11-28

Application of the broad-acting 5-HTR antagonist methiothepin (Bard et al., 1996, Hoyer et al., 1994, Peroutka, 1990) converted the TBS-induced response of both thalamocortical and intracortical A1 synapses from LTP to LTD, an effect that was mimicked by the selective 5-HT2R antagonist ketanserin (L

We next sought to determine the kinase responsible for IR-induced phosphorylation of 53BP1. Because the sites under investigation all lie in a consensus sequence for ATM, ATR and DNA-PK, that are all activated by IR, the involvement of each of these kinases was investigated. Preincubation of (-)-p-B

2023-11-27

Oocytes from the African clawed frog Xenopus laevis have been widely used as an expression system to study the modulation of NMDA receptors by metabotropic receptors, such as metabotropic glutamate receptors [12], μ opioid receptors [13], insulin receptors [14] and serotonin receptors [15]. No data

Placental cells also express P450 aromatase (CYP19A1, encoded by CYP19A1). In the placenta, this enzyme requires an external source of androgens, provided by the adrenal gland of the fetus, to form estrogen. The fetal adrenal gland produces dehydroepiandrosterone (DHEA) [9] and, in the placenta, it

Therefore, we have further investigated the anti-oxidant activity of isogarcinol in vitro by measuring the scavenging of 2,2′-diphenyl-1-1picrylhydrazyl (DPPH) and 2,2′-azino-bia (3-ethylben-zothiazoline-6-sulphonicacid) (ABTS), and determining its reducing power and ability to prevent lipid peroxid

Nanoparticle-Conjugated Topoisomerase Inhibitors The safety and efficacy of topotecan administered as LDM or MTD have been evaluated in several preclinical studies and a few clinical trials whose results showed that there can be significant adverse effects likely precluding its use in patients [5

Introduction Sustained over-activation of neurohormonal systems is a hallmark in the pathophysiology of cardiac dysfunction following myocardial infarction (MI) and heart failure (HF). Inhibitors of the renin-angiotensin selective estrogen receptor modulators system (RAAS) constitute cornerstone

Electron paramagnetic resonance studies of mixtures of Aβ1–40 and Aβ1–42 suggest that interlaced fibrils might also form [40] where Aβ1–40 and Aβ1–42 is found within the same fibril. Considering the Aβ fold rather than the sequence, these observations imply two mechanisms that might lower the total

AAT enzyme activity was readily detected in crude cell-free extracts obtained from berry tissues of all accessions but displayed different substrate selectivities (Fig. 2). Cell-free extracts derived from ‘Muscat Hamburg’ berries showed the highest AAT activity with all alcoholic substrates tested,

The proposed formulation is, however, challenging to solve since the structured sparsity-inducing norms are non-smooth. In order to solve the new objective function, we consider two different approaches: proximal averaging, which takes the average the solutions from the proximal operator for the ind

In the presence of detrimental conditions, such as inflammation, hypoxia, ischemia trauma or neoplastic milieu, the extracellular levels of adenosine increase massively, reaching micromolar range [51,52]. In these pathological contexts, adenosine accumulation stems from increased extracellular depho
