Adenomatous polyposis coli (APC) anchors microtubules to cell membranes and plays an important role in vesicle transport. To clarify the role of APC in vesicle transport in podocytes, nephrotic syndrome was induced by puromycin amino nucleoside (PAN) injection in mice expressing APC1638T lacking the C-terminal of microtubule-binding site (APC1638T mouse); this was examined in renal tissue changes. The kidney size and glomerular area of APC1638T mice were reduced (p = 0.014); however, the number of podocytes was same between wild-type (WT) mice and APC1638T mice. The ultrastructure of podocyte foot process was normal by electron microscopy. When nephrotic syndrome was induced, the kidneys of WT+PAN mice became swollen with many hyaline casts, whereas these changes were inhibited in the kidneys of APC1638T+PAN mice. Electron microscopy showed foot process effacement in both groups; however, APC1638T+PAN mice had fewer vesicles in the basal area of podocytes than WT+PAN mice. Cytoplasmic dynein-1, a motor protein for vesicle transport, and \u03b1-tubulin were significantly reduced in APC1638T+PAN mice associated with suppressed urinary albumin excretion compared to WT+PAN mice. In conclusion, APC1638T mice showed reduced albuminuria associated with suppressed podocyte vesicle transport when minimal change nephrotic syndrome was induced.<\/jats:p>","DOI":"10.3390\/ijms222413412","type":"journal-article","created":{"date-parts":[[2021,12,14]],"date-time":"2021-12-14T09:34:25Z","timestamp":1639474465000},"page":"13412","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Decreased Podocyte Vesicle Transcytosis and Albuminuria in APC C-Terminal Deficiency Mice with Puromycin-Induced Nephrotic Syndrome"],"prefix":"10.3390","volume":"22","author":[{"given":"Saaya","family":"Hatakeyama","sequence":"first","affiliation":[{"name":"Department of Nephrology & Hypertension, Dokkyo Medical University, Tochigi 321-0293, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiro","family":"Tojo","sequence":"additional","affiliation":[{"name":"Department of Nephrology & Hypertension, Dokkyo Medical University, Tochigi 321-0293, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Satonaka","sequence":"additional","affiliation":[{"name":"Department of Nephrology & Hypertension, Dokkyo Medical University, Tochigi 321-0293, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1220-0814","authenticated-orcid":false,"given":"Nami O.","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Gifu University, Gifu 501-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takao","family":"Senda","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Gifu University, Gifu 501-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihiko","family":"Ishimitsu","sequence":"additional","affiliation":[{"name":"Department of Nephrology & Hypertension, Dokkyo Medical University, Tochigi 321-0293, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"551","DOI":"10.1083\/jcb.1.6.551","article-title":"The fine structure of the renal glomerulus of the mouse","volume":"1","author":"Yamada","year":"1955","journal-title":"J.
