We evaluated potential mechanisms using a transgenic (podocin promoter-AA-4E-BP1) rat in which podocyte capacity for hypertrophy in response to growth factor/nutrient signaling is impaired. FSGS lesions resembling human FSGS developed spontaneously by 7 months of age, and could be induced earlier by accelerating kidney hypertrophy by nephrectomy. Early segmental glomerular lesions occurred in the absence of a detectable reduction in average podocyte number per glomerulus and resulted from the loss of podocytes in individual glomerular capillary loops. Parietal epithelial cell division, accumulation on Bowman's capsule, and tuft invasion occurred at these sites. Three different interventions that prevented kidney growth and glomerular enlargement (calorie intake reduction, inhibition of mammalian target of rapamycin complex, and inhibition of angiotensin-converting enzyme) protected against FSGS lesion development, even when initiated late in the process. Ki67 nuclear staining and unbiased transcriptomic analysis identified increased glomerular (but not podocyte) cell cycling as necessary for FSGS lesion development. The rat FSGS-associated transcriptomic signature correlated with human glomerular transcriptomes associated with disease progression, compatible with similar processes occurring in man. We conclude that FSGS lesion development resulted from glomerular growth that exceeded the capacity of podocytes to adapt and adequately cover some parts of the filtration surface. Modest modulation of the growth side of this equation significantly ameliorated FSGS progression, suggesting that glomerular growth is an underappreciated therapeutic target for preservation of renal function.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第441号"}]},"item_10006_publisher_5":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"American Society of Nephrology","subitem_publisher_language":"en"}]},"item_10006_relation_15":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"en","subitem_relation_name_text":"http://hdl.handle.net/10458/6182"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://hdl.handle.net/10458/6182","subitem_relation_type_select":"HDL"}}]},"item_10006_textarea_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_textarea_value":"以下に掲載:Journal of the American Society of Nephrology .2017, Volume28, pp2825-2827, doi:http://dx.doi.org/10.1681/ASN.2017020174"},{"subitem_textarea_language":"ja"}]},"item_10006_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西園, 隆三","creatorNameLang":"ja"},{"creatorName":"ニシゾノ, リュウゾウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"28823","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishizono, Ryuzoh","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"28824","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kikuchi, Masao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8155","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20608476","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20608476"}]},{"creatorNames":[{"creatorName":"Su, Q.
