The roles and applications of extracellular vesicles in cancer
Molecular Oncology, EarlyView.Extracellular vesicles (EVs) are minute versions of cells limited by a lipid bilayer containing cytoplasm from the cell that releases them, but without a nucleus and thus unable to self‐reproduce. EVs contain multiple molecules (proteins, lipids, glycans, and nucleic acids) they can induce complex responses in cells.

Cell Reports, 2023 Summary: The RNA exosome is a versatile ribonuclease. In the nucleoplasm of mammalian cells, it is assisted by its adaptors the nuclear exosome targeting (NEXT) complex and the poly(A) exosome targeting (PAXT) connection.

Red blood cells could protect miRNAs from degradation or loss thanks to Argonaute 2 binding
FEBS Open Bio, EarlyView.The present work investigates the presence and the stability of miRNAs into RBCs, both native and engineered. The observed stability is due to the Ago2 bound resulting in minimal RISC. Indeed, if the miRNA‐Ago2 complex is present, miRNAs are protected from release or degradation and they are biologically active. Thus, RBCs can act as miRNA carriers for

A new yeast poly(A) polymerase complex involved in RNA quality control.
PLoS Biology, 2005 Eukaryotic cells contain several unconventional poly(A) polymerases in addition to the canonical enzymes responsible for the synthesis of poly(A) tails of nuclear messenger RNA precursors.

A Two-Layered Targeting Mechanism Underlies Nuclear RNA Sorting by the Human Exosome
Cell Reports, 2020 Summary: Degradation of transcripts in human nuclei is primarily facilitated by the RNA exosome. To obtain substrate specificity, the exosome is aided by adaptors; in the nucleoplasm, those adaptors are the nuclear exosome-targeting (NEXT) complex and ...

RNA Degradation Assay Using RNA Exosome Complexes, Affinity-purified from HEK-293 Cells
Bio-Protocol, 2017 The RNA exosome complex plays a central role in RNA processing and regulated turnover. Present both in cytoplasm and nucleus, the exosome functions through associations with ribonucleases and various adapter proteins (reviewed in [Kilchert et al., 2016]).

Possible role of human ribonuclease dicer in the regulation of R loops
FEBS Open Bio, EarlyView.R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

EXOSC10 is required for RPA assembly and controlled DNA end resection at DNA double-strand breaks
Nature Communications, 2019 The exosome is a ribonucleolytic complex that plays part in RNA processing and degradation. Here, the authors reveal an RNA clearance event in homologous recombination and show the function of EXOSC10, a component of the exosome, in the homeostasis of ...

Advanced glycation end products promote the release of endothelial cell‐derived mitocytosis
FEBS Open Bio, EarlyView.Under diabetic conditions, AGEs induce mitochondrial damage in HUVECs, activating migrasome‐mediated mitocytosis. Migrasomes encapsulate damaged mitochondria and are released into the extracellular space, facilitating intercellular mitochondrial transfer.
