Mechanistic insights into the protective roles of polyphosphate against amyloid cytotoxicityThis study provides novel insights into the mechanisms by which presence of polyP alters the formation, structural properties, and cytotoxic effects of α-synuclein fibers.
The huntingtin inclusion is a dynamic phase-separated compartmentWhen expressed in yeast, mutant Htt-GFP forms an inclusion that is mobile, gel-like, and releases material; evidence suggests that it grows through collision and coalescence with small aggregates.
Pleiotropic requirements for human TDP-43 in the regulation of cell and organelle homeostasisComprehensive analysis of human TDP-43 knockout cells revealed that TDP-43 regulates hundreds of transcripts and is critical for maintaining the homeostasis of multiple subcellular organelles.
Structural and functional characterization of the mitochondrial complex IV assembly factor Coa6The structures of the mitochondrial complex IV assembly factor Coa6 and a pathogenic mutant variant (W59CCoa6) are reported, providing molecular mechanisms for its mode of action and the loss-of-function mutation.
Endogenous RNAi pathway evolutionarily shapes the destiny of the antisense lncRNAs transcriptomeA genome-wide comparative analysis of “cryptic” aslncRNAs decay in RNAi-capable and RNAi-deficient budding yeasts suggests an evolutionary contribution of RNAi in shaping the aslncRNAs transcriptome.
Mutagenesis of the ADAM17-phosphatidylserine–binding motif leads to embryonic lethality in miceMutation of three cationic amino acids previously identified as an extracellular phosphatidylserine-binding motif abrogates ADAM17 sheddase function and causes early embryonic death in mice.
Targeting plasma membrane phosphatidylserine content to inhibit oncogenic KRAS functionKRAS-dependent cancer cell growth is inhibited by disrupting phosphatidylserine transport to the plasma membrane by genetic knockdown of lipid exchangers ORP5 and ORP8 or by inhibition of PI4KIIIα.
Heterozygous loss of function of IQSEC2/Iqsec2 leads to increased activated Arf6 and severe neurocognitive seizure phenotype in femalesWe show that the loss of Iqsec2 function in mice recapitulates key aspects of the human phenotype, irrespective of the X-inactivation status of the gene between species. Our understanding of the traditional X-chromosome inheritance with heterozygous female sparing needs revisiting.
Plasmalogen loss caused by remodeling deficiency in mitochondria31P NMR unveils cell type–dependent losses of plasmalogen in the chain remodeling–deficient brain, liver, kidney, and lymphoblast in association with aberrant mitochondrial function and morphology.
A molecule inducing androgen receptor degradation and selectively targeting prostate cancer cellsA new molecule induces AR sumoylation and degradation resulting in selective growth inhibition in AR-dependent prostate cancer cells, but its activity is blunted by interference with proteasomes.
