Comparison of Czech hop cultivars based on their contenst of secondary metabolites

open access: yesCzech Journal of Food Sciences, 2010
Seven Czech hop varieties (dry hop cones) coming from the harvest of 2008 (Agnus, Bor, Harmonie, Premiant, Rubín, Sládek, and Saaz) were compared for their composition depending on their varietal differentiation.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Effect of β-Glucan on cold-stress resistance of striped catfish, Pangasianodon hypophthalmus (Sauvage, 1878)

open access: yesVeterinární Medicína, 2014
These experiments were performed to determine the effects of dietary β-glucan on stress responses of striped catfish (Pangasianodon hypophthalmus). Fish were fed for nine weeks with a diet containing 0 (control), 0.5% (G1), 1% (G2) and 2% (G3 group) β ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

The effect of elicitors on oleanolic acid accumulation and expression of triterpenoid synthesis genes in Gentiana straminea

open access: yesBiologia Plantarum, 2013
Gentiana straminea is native to the Qinghai-Tibet plateau, where it is exposed to extremes of cold and strong UV-B radiation. Here we showed that low temperature, but not UV-B radiation, affected the accumulation of the triterpenoid oleanolic acid ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Knockout mutants of Arabidopsis thaliana β-galactosidase. Modifications in the cell wall saccharides and enzymatic activities

open access: yesBiologia Plantarum, 2018
This work studied the six β-galactosidases (BGALs) of the subfamily a1 of Arabidopsis, that have been proposed to play important roles in the cell wall remodelling during plant development, although their precise functions are still unknown.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
