Inhibition of gene expression by RNase P
New Biotechnology, 2010 The ability to interfere with gene expression is of crucial importance to unravel the function of genes and is also a promising therapeutic strategy. Here we discuss methodologies for inhibition of target RNAs based on the cleavage activity of the essential enzyme, Ribonuclease P (RNase P).

Cryo-electron microscopy structure of an archaeal ribonuclease P holoenzyme
Nature Communications, 2019 Ribonulease P is a conserved ribozyme present in all kingdoms of life that is involved in the 5′ maturation step of tRNAs. Here the authors determine the structure of an archaeal RNase P holoenzyme that reveals how archaeal RNase P recognizes its tRNA ...

Uniformity amid diversity in RNase P [PDF]
Proceedings of the National Academy of Sciences, 2007 The ribonucleoprotein RNase P, which catalyzes the Mg2+-dependent removal of the 5′ leader sequence in all precursor tRNAs (ptRNAs), is remarkable for the diversity in its subunit composition (Fig. 1 A). Although all RNase P holoenzymes have an essential RNA subunit, the number of protein subunits varies from 1 in Bacteria to at least 4 in Archaea and ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

FEBS Open Bio, EarlyView.In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

, 2013 Ribonuklease P (RNase P) ist eine Endonuklease, die die 5´ Flanke von pre-tRNAs entfernt und somit essentiell für die Funktion von tRNAs in der Proteinsynthese ist.

BMC Microbiology, 2012 Background Ribonuclease R (RNase R) is an exoribonuclease that recognizes and degrades a wide range of RNA molecules. It is a stress-induced protein shown to be important for the establishment of virulence in several pathogenic bacteria. RNase R has also
