abstract = {Microsatellite unstable (MSI) colorectal cancers (CRCs) are
characterized by mutational inactivation of Transforming
Growth Factor Beta Receptor Type 2 (TGFBR2).
TGFBR2-deficient CRCs present altered target gene and
protein expression. Such cellular alterations modulate the
content of CRC-derived extracellular vesicles (EVs). EVs
function as couriers of proteins, nucleic acids, and lipids
in intercellular communication. At a qualitative level, we
have previously shown that TGFBR2 deficiency causes overall
alterations in the EV protein content. To deepen the basic
understanding of altered protein dynamics, this work aimed
to determine TGFBR2-dependent EV protein signatures in a
quantitative manner. Using a stable isotope labeling with
amino acids in cell culture (SILAC) approach for mass
spectrometry-based quantification, 48 TGFBR2-regulated
proteins were identified in MSI CRC-derived EVs. Overall,
TGFBR2 deficiency caused upregulation of several EV proteins
related to the extracellular matrix and nucleosome as well
as downregulation of proteasome-associated proteins. The
present study emphasizes the general overlap of proteins
between EVs and their parental CRC cells but also highlights
the impact of TGFBR2 deficiency on EV protein composition.
From a clinical perspective, TGFBR2-regulated quantitative
differences of protein expression in EVs might nominate
novel biomarkers for liquid biopsy-based MSI typing in the
future.},
