Mutations in thiamine transporter, TDP synthesizing enzyme or\u00a0carrier, including solute carrier family 19 member 3 (<jats:italic>SLC19A3<\/jats:italic>), thiamine pyrophosphokinase (<jats:italic>TPK1<\/jats:italic>) and solute carrier family 25 member 19 (<jats:italic>SLC25A19<\/jats:italic>), have been associated with developmental neurological disorders, including microcephaly and Leigh syndrome. However, little is known about how thiamine metabolism regulates neuronal morphology at the cellular level. Here, using primary rat hippocampal neuronal cultures, we showed that reducing the expression of<jats:italic>Tpk1<\/jats:italic>,<jats:italic>Slc25a19<\/jats:italic>or<jats:italic>Slc19a3<\/jats:italic>in individual neurons significantly reduced dendrite complexity, as measured by total dendritic branch tip number (TDBTN) and total dendritic branch length (TDBL). The specificity of the RNAi effects were verified by overexpression of RNAi resistant human constructs. Importantly, changes in both TDBTN and TDBL tightly correlated with reduction in soma size, demonstrating coordinated regulation of soma and dendrite growth by thiamine. The requirement of thiamine metabolism for coordinated somata and dendrite growth is highly consistent with the microcephaly and neurodegenerative phenotypes observed in thiamine loss-of-function diseases.<\/jats:p>","DOI":"10.1038\/s41598-017-05476-w","type":"journal-article","created":{"date-parts":[[2017,7,7]],"date-time":"2017-07-07T11:53:41Z","timestamp":1499428421000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Thiamine metabolism is critical for regulating correlated growth of dendrite arbors and neuronal somata"],"prefix":"10.1038","volume":"7","author":[{"given":"Huimin","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaoming","family":"Sang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongfeng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunjiu","family":"Zhong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2017,7,13]]},"reference":[{"key":"5476_CR1","doi-asserted-by":"publisher","first-page":"821","DOI":"10.1021\/bi401618y","volume":"53","author":"S Manzetti","year":"2014","unstructured":"Manzetti, S., Zhang, J. & van der Spoel, D.
