EXOSC10 is required for RPA assembly and controlled DNA end resection at DNA double-strand breaks [PDF]

open access: yes, 2019
The exosome is a ribonucleolytic complex that plays important roles in RNA metabolism. Here we show that the exosome is necessary for the repair of DNA double-strand breaks (DSBs) in human cells and that RNA clearance is an essential step in homologous ...

A Quantitative Pharmacology Model of Exosome-Mediated Drug Efflux and Perturbation-Induced Synergy

open access: yesPharmaceutics, 2021
Exosomes, naturally occurring vesicles secreted by cells, are undergoing development as drug carriers. We used experimental and computational studies to investigate the kinetics of intracellular exosome processing and exosome-mediated drug efflux and the

The Exosome Subunit Rrp44 Plays a Direct Role in RNA Substrate Recognition [PDF]

open access: yes, 2007
The exosome plays key roles in RNA maturation and surveillance, but it is unclear how target RNAs are identified. We report the functional characterization of the yeast exosome component Rrp44, a member of the RNase II family.

The link between gestational diabetes and cardiovascular diseases: potential role of extracellular vesicles

open access: yesCardiovascular Diabetology, 2022
Extracellular vesicles are critical mediators of cell communication. They encapsulate a variety of molecular cargo such as proteins, lipids, and nucleic acids including miRNAs, lncRNAs, circular RNAs, and mRNAs, and through transfer of these molecular ...

Cholesterol Regulates Exosome Release in Cultured Astrocytes

open access: yesFrontiers in Immunology, 2021
Exosomes are vesicles secreted by various kinds of cells, and they are rich in cholesterol, sphingomyelin (SM), phosphatidylcholine, and phosphatidylserine.

Exosome Manufacturing Status [PDF]

open access: yesFuture Medicinal Chemistry, 2019
Exosomes are secreted by mammalian cells and are widely distributed in cellular systems. They are a medium of information and material transmission. The complexity of exosome nature and function is not thoroughly understood. Nevertheless, they are being confirmed as mediators of intercellular communication and play significant roles in many ...

A proteomic atlas of senescence-associated secretomes for aging biomarker development. [PDF]

open access: yes, 2020
The senescence-associated secretory phenotype (SASP) has recently emerged as a driver of and promising therapeutic target for multiple age-related conditions, ranging from neurodegeneration to cancer.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Reviving the Exosome [PDF]

open access: yesCell, 2005
In the nucleus of eukaryotic cells, RNA decay in the 3'-5' direction is carried out by a complex of exonucleases called the exosome. Surprisingly, the purified exosome shows only weak activity in vitro. Two papers in this issue of Cell, by LaCava et al. (2005) and Wyers et al. (2005), and a third report by Vanacova et al.

PYCR1 inhibition in bone marrow stromal cells enhances bortezomib sensitivity in multiple myeloma cells by altering their metabolism

open access: yesMolecular Oncology, EarlyView.
This study investigated how PYCR1 inhibition in bone marrow stromal cells (BMSCs) indirectly affects multiple myeloma (MM) cell metabolism and viability. Culturing MM cells in conditioned medium from PYCR1‐silenced BMSCs impaired oxidative phosphorylation and increased sensitivity to bortezomib.
