text: Solute carriers are increasingly recognized as participating in a plethora
of pathologies, including cancer. We describe here the involvement of the orphan
solute carrier MFSD1 in the regulation of tumor cell migration. Loss of MFSD1
enabled higher levels of metastasis in a mouse model. We identified an increased
migratory potential in MFSD1-/- tumor cells which was mediated by increased focal
adhesion turn-over, reduced stability of mature inactive β1 integrin, and the
resulting increased integrin activation index. We show that MFSD1 promoted recycling
to the cell surface of endocytosed inactive β1 integrin and thereby protected
β1 integrin from proteolytic degradation; this led to dampening of the integrin
activation index. Furthermore, down-regulation of MFSD1 expression was observed
during early steps of tumorigenesis and higher MFSD1 expression levels correlate
with a better cancer patient prognosis. In sum, we describe a requirement for
endolysosomal MFSD1 in efficient β1 integrin recycling to suppress tumor spread.
