Matsuoka et al. investigated how diet-regulated........<\/jats:p><jats:p>Elevated levels of human chitinase-like proteins (CLPs) are associated with numerous chronic inflammatory diseases and several cancers, often correlating with poor prognosis. Nevertheless, there is scant knowledge of their function. The CLPs normally mediate immune responses and wound healing and, when upregulated, they can promote disease progression by remodeling tissue, activating signaling cascades, stimulating proliferation and migration, and by regulating adhesion. We identified Imaginal disc growth factors (Idgfs), orthologs of human CLPs CHI3L1, CHI3L2, and OVGP1, in a proteomics analysis designed to discover factors that regulate tube morphogenesis in a Drosophila melanogaster model of tube formation. We implemented a novel approach that uses magnetic beads to isolate a small population of specialized ovarian cells, cells that nonautonomously regulate morphogenesis of epithelial tubes that form and secrete eggshell structures called dorsal appendages (DAs). Differential mass spectrometry analysis of these cells detected elevated levels of four of the six Idgf family members (Idgf1, Idgf2, Idgf4, and Idgf6) in flies mutant for bullwinkle (bwk), which encodes a transcription factor and is a known regulator of DA-tube morphogenesis. We show that, during oogenesis, dysregulation of Idgfs (either gain or loss of function) disrupts the formation of the DA tubes. Previous studies demonstrate roles for Drosophila Idgfs in innate immunity, wound healing, and cell proliferation and motility in cell culture. Here, we identify a novel role for Idgfs in both normal and aberrant tubulogenesis processes.<\/jats:p>","DOI":"10.1534\/genetics.116.199323","type":"journal-article","created":{"date-parts":[[2017,4,13]],"date-time":"2017-04-13T01:20:40Z","timestamp":1492046440000},"page":"973-984","source":"Crossref","is-referenced-by-count":19,"title":["Proteomics Analysis Identifies Orthologs of Human Chitinase-Like Proteins as Inducers of Tube Morphogenesis Defects in<i>Drosophila melanogaster<\/i>"],"prefix":"10.1093","volume":"206","author":[{"given":"Sandra G","family":"Zimmerman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gennifer E","family":"Merrihew","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael J","family":"MacCoss","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Celeste A","family":"Berg","sequence":"additional","affiliation":[{"name":"Department of Genome Sciences , University of Washington, Seattle, Washington 98195-5065"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2017,6,1]]},"reference":[{"key":"2023030910503703000_","doi-asserted-by":"crossref","first-page":"34","DOI":"10.1016\/j.ydbio.2009.09.024","article-title":"Morphogenesis of epithelial tubes: insights into tube formation, elongation, and elaboration.","volume":"341","author":"Andrew","year":"2010","journal-title":"Dev.
