text: Aberrant display of the truncated core1 O-glycan T-antigen is a common feature
of human cancer cells that correlates with metastasis. Here we show that T-antigen
in Drosophila melanogaster macrophages is involved in their developmentally programmed
tissue invasion. Higher macrophage T-antigen levels require an atypical major
facilitator superfamily (MFS) member that we named Minerva which enables macrophage
dissemination and invasion. We characterize for the first time the T and Tn glycoform
O-glycoproteome of the Drosophila melanogaster embryo, and determine that Minerva
increases the presence of T-antigen on proteins in pathways previously linked
to cancer, most strongly on the sulfhydryl oxidase Qsox1 which we show is required
for macrophage tissue entry. Minerva’s vertebrate ortholog, MFSD1, rescues the
minerva mutant’s migration and T-antigen glycosylation defects. We thus identify
a key conserved regulator that orchestrates O-glycosylation on a protein subset
to activate a program governing migration steps important for both development
and cancer metastasis.

text: "Invasive migration plays a crucial role not only during development and homeostasis
but also in pathological states, such as tumor metastasis. Drosophila macrophage
migration into the extended germband is an interesting system to study invasive
migration. It carries similarities to immune cell transmigration and cancer cell
invasion, therefore studying this process could also bring new understanding of
invasion in higher organisms. In our work, we uncover a highly conserved member
of the major facilitator family that plays a role in tissue invasion through regulation
of glycosylation on a subgroup of proteins and/or by aiding the precise timing
of DN-Cadherin downregulation. \r\n\r\nAberrant display of the truncated core1
O-glycan T-antigen is a common feature of human cancer cells that correlates with
metastasis. Here we show that T-antigen in Drosophila melanogaster macrophages
is involved in their developmentally programmed tissue invasion. Higher macrophage
T-antigen levels require an atypical major facilitator superfamily (MFS) member
that we named Minerva which enables macrophage dissemination and invasion. We
characterize for the first time the T and Tn glycoform O-glycoproteome of the
Drosophila melanogaster embryo, and determine that Minerva increases the presence
of T-antigen on proteins in pathways previously linked to cancer, most strongly
on the sulfhydryl oxidase Qsox1 which we show is required for macrophage tissue
entry. Minerva’s vertebrate ortholog, MFSD1, rescues the minerva mutant’s migration
and T-antigen glycosylation defects. We thus identify \r\na key conserved regulator
that orchestrates O-glycosylation on a protein subset to activate \r\na program
governing migration steps important for both development and cancer metastasis.
