G-rich RNAs encoded in mitochondrial DNA are prone to form four-stranded structures called G-quadruplexes (G4s). Here the authors show using in vitro and in vivo approaches that GRSF1 promotes melting of G4 RNA structures in mtRNAs, thus leading to t

Transcription of the human mitochondrial genome produces a vast amount of non-coding antisense RNAs. These RNA species can form G-quadraplexes (G4), which affect their decay. We found that the mitochondrial degradosome, a complex of RNA helicase SUPV

Bezafibrate (BZ) regulates mitochondrial biogenesis by activation of PPAR’s receptors and enhancing the level of PGC-1α coactivator. In this report, we investigated the effect of BZ on the expression of genes (1) that are linked to different pathw

The GC skew in vertebrate mitochondrial genomes results in synthesis of RNAs that are prone to form G-quadruplexes (G4s). Such RNAs, although mostly non-coding, are transcribed at high rates and are degraded by an unknown mechanism. Here we describe

Upconverting Gd2O3 nanoparticles (NPs) doped 1% Er3+ and 18% Yb3+ permits one to perform optical imaging. Because of the presence of Gd3+ they are useful in MRI. The main challenge is to enhance the NPs upconversion efficiency. As a result of co-dopi
