Acacetin reduces endoplasmic reticulum stress through the P‐eNOS/PERK signaling pathway to attenuate MGO‐induced vascular endothelial cell dysfunction

FEBS Open Bio, EarlyView.
We investigated a potential protective effect of acacetin, a naturally occurring flavonoid, against methylglyoxal (MGO)‐induced endothelial dysfunction in human umbilical vein endothelial cells and its mechanism of action. Acacetin can could inhibit MGO‐induced intracellular calcium ion influx, enhance the expression levels of phosphorylated ...

Decoupling in an expanding universe: boundary RG-flow affects initial conditions for inflation

, 2004
We study decoupling in FRW spacetimes, emphasizing a Lagrangian description throughout. To account for the vacuum choice ambiguity in cosmological settings, we introduce an arbitrary boundary action representing the initial conditions.

Piezo1 channels enhance anabolic signaling activation induced by electrical stimulation of cultured myotubes

FEBS Open Bio, EarlyView.
By using an electrical pulse stimulation (EPS)‐based in vitro exercise model and chemical activation/inhibition of mechanosensitive Piezo1 channels, we explored changes in protein synthetic response in cultured C2C12 myotubes. Our data showed that application of Piezo1 activator (Yoda1) during EPS significantly enhances the rate of protein synthesis in

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

FEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

On the origin of quantum mechanics

, 2005
Action at distance in Newtonian physics is replaced by finite propagation speeds in classical post--Newtonian physics. As a result, the differential equations of motion in Newtonian physics are replaced by functional differential equations, where the ...

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible
