Temporal landscape of mitochondrial proteostasis governed by the UPRmtBreakdown of mitochondrial proteostasis activates quality control pathways including the mitochondrial unfolded protein response (UPRmt) and PINK1/Parkin mitophagy. However, beyond the up-regulation of chaperones and proteases, we have a limited understanding of how the UPRmt remodels and restores damaged mitochondrial proteomes.

ATFS-1 counteracts mitochondrial DNA damage by promoting repair over transcriptionThe ability to balance conflicting functional demands is critical for ensuring organismal survival. The transcription and repair of the mitochondrial genome requires separate enzymatic activities that can sterically compete, suggesting a life-long trade-off between these two processes.

Stem cell ‘memory’ discovery offers hope for new disease breakthroughsAustralian researchers have developed a new method to ‘wipe the memory’ of reprogrammed human cells to better mimic embryonic stem cells, in a discovery that has significant implications for the treatment of several serious diseases.

Multi-omic profiling reveals an RNA processing rheostat that predisposes to prostate cancerProstate cancer is the most commonly diagnosed malignancy and the third leading cause of cancer deaths. GWAS have identified variants associated with prostate cancer susceptibility; however, mechanistic and functional validation of these mutations is lacking.

Molecular basis of translation termination at noncanonical stop codons in human mitochondriaThe genetic code that specifies the identity of amino acids incorporated into proteins during protein synthesis is almost universally conserved. Mitochondrial genomes feature deviations from the standard genetic code, including the reassignment of two arginine codons to stop codons.

Mutational rescue of the activity of high-fidelity Cas9 enzymesProgrammable DNA endonucleases derived from bacterial genetic defense systems, exemplified by CRISPR-Cas9, have made it significantly easier to perform genomic modifications in living cells. However, unprogrammed, off-target modifications can have serious consequences, as they often disrupt the function or regulation of non-targeted genes and compromise the safety of therapeutic gene editing applications.
