Polarised Asymmetric Inheritance of Accumulated Protein Damage in Higher Eukaryotes

Polarised Asymmetric Inheritance of Accumulated Protein Damage in Higher Eukaryotes

Disease-associated misfolded proteins or proteins damaged due to cellular stress are generally disposed via the cellular protein quality-control system. However, under saturating conditions, misfolded proteins will aggregate. In higher eukaryotes, these aggregates can be transported to accumulate in aggresomes at the microtubule organizing center. The fate of cells that contain aggresomes is cu...

Protein components of mitochondrial DNA nucleoids in higher eukaryotes.

Mitochondrial DNA (mtDNA) is not packaged in nucleosomal particles, but has been reported to associate with the mitochondrial inner membrane. Gentle lysis of Xenopus oocyte mitochondria with nonionic detergent liberates a nucleoprotein complex containing mtDNA associated with a previously characterized DNA binding partner, mitochondrial transcription factor A (mtTFA), as well as a series of inn...

A systematic review of the asymmetric inheritance of cellular organelles in eukaryotes: A critique of basic science validity and imprecision

We performed a systematic review to identify all original publications describing the asymmetric inheritance of cellular organelles in normal animal eukaryotic cells and to critique the validity and imprecision of the evidence. Searches were performed in Embase, MEDLINE and Pubmed up to November 2015. Screening of titles, abstracts and full papers was performed by two independent reviewers. Dat...

Asymmetric inheritance of cytoophidia in Schizosaccharomyces pombe

A general view is that Schizosaccharomyces pombe undergoes symmetric cell division with two daughter cells inheriting equal shares of the content from the mother cell. Here we show that CTP synthase, a metabolic enzyme responsible for the de novo synthesis of the nucleotide CTP, can form filamentous cytoophidia in the cytoplasm and nucleus of S. pombe cells. Surprisingly, we observe that both c...
