2022-08-24
Another level of complexity within the TGF-ß/SMAD and Hippo/YAP/TAZ pathway crosstalks was recently uncovered. TGF-ß induces robust TAZ, but not YAP, protein expression in both mesenchymal and epithelial SC 560 through a SMAD3-independent, p38/MAPK-dependent mechanism that triggers myocardin-relate

We report herein an electrochemical analysis of the interaction between L1 and sGC, where conventional solution phase voltammetry is combined with a novel technique, the voltammetry of microparticles (VMP), in order to obtain mechanistic information on the deactivation of sGC by L1. The VMP is a sol

Furthermore, a direct thiol protective role of S-nitrosylation has been reported in animals [66]. Here, formation of higher order irreversible oxidative modifications, such as sulfinic and sulfonic acids were prevented by S-nitrosylation. All these observations underline the important role of ROS in

Likewise, and considering the aforementioned biological actions of ketogenic diet-derived MCFA on neuronal excitability, it could be postulated that specific receptors for fatty acids could also be involved. For example, the GPCR for medium to long chain fatty acids, FFA1/GPR40, might also contribut

Long non coding RNAs lncRNAs
2022-08-24
Long non-coding RNAs (lncRNAs) are mRNA-like transcripts of greater than 200 nucleotides (nt), with little or no protein-coding potential [13,14]. LncRNAs have been suggested to participate in transcription and post-transcription regulation as scaffolds, guides, decoys or repressors, activators, and

Yeast two-hybrid screening studies have provided the foundation for countless investigations of protein-protein interactions [[141], [142], [143]]. To identify additional hepatic proteins similar to GKRP that are implicated in GCK regulation, a group of researchers conducted a two-hybrid study using

2022-08-23
The mechanism underlying the anorectic effect of OXM is well established. It is centrally mediated via GLP-1 receptor activation, confirmed by both pharmacological blockade of the GLP-1 receptor, and using GLP-1 receptor knock-out mice [2], [11], [12]. However, the mechanism by which it increases en

γ-Secretase in inflammatory diseases γ-Secretase appears to play a more important role than previously recognized in inflammatory diseases. Studies have shown that mice partially deficient in PS genes (PS1+/− PS2−/−) develop an immune system deficit in late adulthood, such as ulcerated skin or a

Cellular inhibition is caused by the hyperpolarization of the cell and is mediated by both synaptic and extrasynaptic GABAARs. Synaptic GABAARs are sensitive to high concentrations of GABA released at the synapse and mediate phasic inhibition. In contrast, extrasynaptic GABAARs mediate tonic inhibit

Recently, accumulated evidence has revealed a close link of FXR to gluconeogenesis. For example, activation of FXR by its agonist GW4064 improved hyperglycemia in db/db mice by repressing gluconeogenesis [15], and FXR agonist CDCA decreased transactivation activity of key gluconeogenic genes by indu

Two types of processes, intrinsic and extrinsic, contribute synergistically to the age-related change on structural integrity and physiological function of the skin (Farage, Miller, Elsner, & Maibach, 2008). Intrinsic aging arise from genetically programmed cell aging, normal metabolic activities, a

Another lever to efficiently eradicate tumors including ovarian cancer might rely on their high addiction to iron [34]. In fact, ultrasmall silica-based nanoparticles, functionalized with melanoma-targeting peptide, efficiently triggered ferroptosis not only in cell culture but also in tumor bearing
