Exosome-mediated transfer of miR-222 is sufficient to increase tumor malignancy in melanoma [PDF]

open access: yes, 2016
BACKGROUND: Growing evidence is showing that metastatic cell populations are able to transfer their characteristics to less malignant cells. Exosomes (EXOs) are membrane vesicles of endocytic origin able to convey their cargo of mRNAs, microRNAs (miRs),

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.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

The Role of CDR1as in Proliferation and Differentiation of Human Umbilical Cord-Derived Mesenchymal Stem Cells

open access: yesStem Cells International, 2019
Mesenchymal stem cells derived from human umbilical cord (hucMSCs) are considered a promising tool for regenerative medicine. circRNAs as newly discovered noncoding RNAs are involved in multiple biological processes.

Development of an Organ-Directed Exosome-Based siRNA-Carrier Derived from Autologous Serum for Lung Metastases and Testing in the B16/BL6 Spontaneous Lung Metastasis Model

open access: yesPharmaceutics, 2022
Exosomes are nano-sized extracellular vesicles that are known to carry various messages to distant cells. It was recently reported that cancer-derived exosomes are orientated to metastatic organs. However, there are no reports on drug carrier development

Extracellular vesicle-induced differentiation of neural stem progenitor cells [PDF]

open access: yes, 2019
Neural stem progenitor cells (NSPCs) from E13.5 mouse embryos can be maintained in culture under proliferating conditions. Upon growth-factor removal, they may differentiate toward either neuronal or glial phenotypes or both.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Development of Stable Cell Lines for the Production of Hematopoietic Stem Cell Targeted Exosomes [PDF]

open access: yes, 2018
Exosomes represent a promising new approach to targeted drug delivery. Current research explores the ability of these naturally occurring nanoparticles to transport therapeutic cargo to specific tissues of the body and to subsequently enter the cells of ...

Exosomal αvβ6 integrin is required for monocyte M2 polarization in prostate cancer [PDF]

open access: yes, 2018
Therapeutic approaches aimed at curing prostate cancer are only partially successful given the occurrence of highly metastatic resistant phenotypes that frequently develop in response to therapies.
