    Science bears some hallmarks of religion. But, unlike many organized religions, there is no central authority and no tenet remains unchallenged.

    Scientists and commercial scientific instrument makers have a shared incentive against discloseing an instrument maker's contributions to research. Stricter rules to encourage reporting of such collaboration would help to improve transparency and reproducibility.

    The reproducibility crisis in biomedical research has spurred much debate about the causes of the failure to validate experimental results. But the discussion may be overlooking one crucial factor that is inherent to research with low sample sizes: random variation.

    Mitochondrial adaptation in obesity is a ClpPicated business
    Mitochondrial adaptation in obesity is a ClpPicated business

    Quality control systems that maintain mitochondrial oxidative phosphorylation (OXPHOS) include rescue by mitochondrial fusion, elimination of dysfunctional mitochondria by mitophagy, and degradation of damaged proteins by proteases. ClpP is an ATP‐dependent protease located in the mitochondrial matrix and mutated in Perrault syndrome, causing gonadal atrophy and hearing loss. Given that hearing loss is common in mitochondrial diseases caused by mtDNA mutations, ClpP was proposed to be part of the quality control system to maintain proper mitochondrial OXPHOS function. Two recent studies independently report that deletion of ClpP in mice protects from insulin resistance and obesity by increasing mitochondrial OXPHOS capacity and browning in gonadal white adipose tissue and mitochondrial coupling in brown adipose tissue [1], [2]. Furthermore, liver‐ and muscle‐specific deletion of ClpP has no major effects on insulin resistance. These studies reveal that ClpP might be involved in tissue‐specific mitochondrial remodeling in response to metabolic demands, rather than exclusively removing damaged proteins to maintain OXPHOS capacity.

    Two recent studies independently show that loss of the mitochondrial protease ClpP protects mice from insulin resistance and diet‐induced obesity.

    Elevated levels of the transcriptional regulators TAZ/YAP, key effectors of Hippo pathway signalling, mediate breast cancer cell growth dependence on exogenous glutamine. Cancer cells with high TAZ/YAP activity are sensitive to transaminase inhibition.

    Synopsis

    Elevated levels of the transcriptional regulators TAZ/YAP, key effectors of Hippo pathway signalling, mediate breast cancer cell growth dependence on exogenous glutamine. Cancer cells with high TAZ/YAP activity are sensitive to transaminase inhibition.

    • High TAZ/YAP levels alter cellular energetics to promote breast cancer cell growth dependence on exogenous glutamine.

    • TAZ/YAP promote the expression of glutamic–oxaloacetic transaminase (GOT1) and phosphoserine aminotransferase (PSAT1).

    • Transaminase inhibition represses breast cancer cell growth in a TAZ/YAP dependent manner.

    The scavenger receptor CD36 and its ligand amyloid beta trigger NF‐κB pathway activation and the acquisition of a senescence‐associated secretory phenotype (SASP) in response to various senescence‐inducing stimuli.

    Synopsis

    In response to various senescence‐inducing stimuli, normal mammalian cells rapidly upregulate the scavenger receptor CD36. Amyloid beta‐dependent CD36 signaling then triggers NF‐κB pathway activation, resulting in the production and secretion of numerous inflammatory proteins known to comprise the senescence‐associated secretory phenotype.

    • The multi‐ligand receptor CD36 is induced in multiple senescence contexts.

    • Amyloid beta activates CD36 to stimulate NF‐κB‐dependent cytokine and chemokine production.

    • Sustained secretory molecule production leads to the onset of a comprehensive senescent cell fate.

    The GTPase Mitofusin mediates mitochondrial fusion, but the underlying mechanism of membrane fusion remains unclear. This study shows that the amphipathic nature of the heptad repeat domain 1 (HR1) of Mitofusin perturbs the lipid bilayer structure to drive mitochondrial fusion.

    Synopsis

    The GTPase Mitofusin mediates mitochondrial fusion, but the underlying mechanism of membrane fusion remains unclear. This study shows that the amphipathic nature of the heptad repeat domain 1 (HR1) of Mitofusin perturbs the lipid bilayer structure to drive mitochondrial fusion.

    • HR1 is required for Mitofusin‐mediated mitochondrial fusion in cultured cells, and induces liposome fusion in vitro.

    • The membrane fusion activity of HR1 is associated with its capacity to insert into lipid bilayers, notably in regions presenting lipid packing defects.

    • This property is conferred by a conserved amphipathic helix located at the C‐terminus of the HR1 sequence.

    The innate immune RNA sensor LGP2 is a negative regulator of antiviral signal transduction. LGP2 interferes with TRAF ubiquitin ligase activity, thereby suppressing TRAF‐dependent signaling to prevent activation of IRF3 and NFκB.

    Synopsis

    The innate immune RNA sensor LGP2 is a negative regulator of antiviral signal transduction. LGP2 interferes with TRAF ubiquitin ligase activity, thereby suppressing TRAF‐dependent signaling to prevent activation of IRF3 and NFκB.

    • LGP2 interferes with IRF3 and NFκB antiviral signaling downstream of MAVS.

    • LGP2 co‐precipitates with and disrupts TRAF protein signaling and ubiquitin ligase activity.

    • LGP2 can act in trans to negatively regulate diverse TRAF signaling systems.

    • This regulatory activity does not depend on RNA binding, ATP hydrolysis, or its C‐terminal domain.

    Extensive crosstalk between microRNAs and alternative splicing programs shapes the transcriptome of ESCs. The miR‐290/302 family and Mbnl1/2 proteins opposingly regulate alternative splicing and gene expression, thereby influencing cell fate determination.

    Synopsis

    Extensive crosstalk between microRNAs and alternative splicing programs shapes the transcriptome of ESCs. The miR‐290/302 family and Mbnl1/2 proteins opposingly regulate alternative splicing and gene expression, thereby influencing cell fate determination.

    • A subset of alternative splicing events in ESCs depends on the miR‐290/302 family.

    • miR‐294 regulates alternative splicing events by repressing the splicing regulators Mbnl1/2.

    • Mbnl1/2 counteracts miR‐294 by binding and promoting the expression of its key targets.

    eIF5A is required for lipidation of ATG8 proteins and autophagosome formation. This results from eIF5A‐mediated translation of the E2‐like ATG3 protein, which contains an amino acid motif causing eIF5A dependency for its efficient translation.

    Synopsis

    Eukaryotic translation initiation factor 5A (eIF5A) is required for lipidation of ATG8 proteins and autophagosome formation. This results from eIF5A‐mediated translation of the E2‐like ATG3 protein, which contains an amino acid motif causing eIF5A dependency for its efficient translation.

    • A high‐throughput screen identifies eIF5A as a translational requirement of autophagy.

    • eIF5A facilitates autophagosome formation by facilitating translation of ATG3.

    • A tri‐peptide motif in ATG3 causes eIF5A dependency for its efficient translation.

    • Induction of autophagy causes enhanced association of eIF5A with the ribosome.
