So far, a growing number of porcine miRNAs and their function have been identified, but little is known regarding the porcine developing hypothalamus and pituitary. In the present study, Solexa sequencing analysis showed 14,129,397 yielded reads, 6,680,678 of which were related to 674 unique miRNAs. After a microarray assay, we detected 175 unique miRNAs in the hypothalamus, including 136 previously known miRNAs and 39 novel candidates, while a total of 140 miRNAs, including 104 known and 36 new candidate miRNAs, were discovered in pituitary. More importantly, 37 and  30 differentially expressed miRNAs from several developmental stages of hypothalamus and pituitary were revealed, respectively. The 37 differentially expressed miRNAs in hypothalamus represented 6 different expression patterns, while the 30 differentially expressed miRNAs in pituitary represented 7 different expression patterns. To clarify potential target genes and specific functions of these differentially expressed miRNAs in hypothalamus and pituitary, TargetScan and Gorilla prediction tools were then applied. The current functional analysis showed that the differentially expressed miRNAs in hypothalamus and pituitary shared many biological processes, with the main differences being found in  tissue-specific processes including: CDP-diacylglycerol biosynthetic\/metabolic process; phosphatidic acid biosynthetic\/metabolic process; energy reserve metabolic process for hypothalamus; adult behavior; sterol transport\/homeostasis; and cholesterol\/reverse cholesterol transport for pituitary. Overall, this study identified miRNA profiles and differentially expressed miRNAs among various developmental stages in hypothalamus and pituitary and indicated miRNA profiles change with age and brain location, enhancing our knowledge about spatial and temporal expressions of miRNAs in the porcine developing brain.<\/jats:p>","DOI":"10.3390\/ijms141020326","type":"journal-article","created":{"date-parts":[[2013,10,14]],"date-time":"2013-10-14T11:11:20Z","timestamp":1381749080000},"page":"20326-20339","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["MicroRNA Expression Profiling of the Porcine Developing Hypothalamus and Pituitary Tissue"],"prefix":"10.3390","volume":"14","author":[{"given":"Lifan","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Animal Science, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaowei","family":"Cai","sequence":"additional","affiliation":[{"name":"Laboratory Animal Research Center, Zhejiang Chinese Medical University, Hangzhou 310053, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengjuan","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Washington State University, Pullman, WA 99164, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiyun","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Animal Science, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongmei","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Animal Science, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoling","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Animal Science, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ningying","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Animal Science, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2013,10,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1097\/PPO.0b013e318258b771","article-title":"Cross talk between microRNA and coding cancer genes","volume":"18","author":"Kunej","year":"2012","journal-title":"Cancer J"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"843","DOI":"10.1016\/0092-8674(93)90529-Y","article-title":"The C. elegans heterochronic gene lin-4 encodes small RNAs with antisense complementarity to lin-14","volume":"75","author":"Lee","year":"1993","journal-title":"Cell"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"92","DOI":"10.1101\/gr.082701.108","article-title":"Most mammalian mRNAs are conserved targets of microRNAs","volume":"19","author":"Friedman","year":"2009","journal-title":"Genome Res"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1016\/j.cell.2008.12.027","article-title":"MicroRNA control in the immune system: Basic principles","volume":"136","author":"Xiao","year":"2009","journal-title":"Cell"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"e11541","DOI":"10.1371\/journal.pone.0011541","article-title":"MicroRNAome of porcine pre- and postnatal development","volume":"5","author":"Li","year":"2010","journal-title":"PLoS One"},{"key":"ref_6","doi-asserted-by":"crossref","first-page":"1318","DOI":"10.1002\/jcb.23045","article-title":"MicroRNA identity and abundance in developing swine adipose tissue as determined by Solexa sequencing","volume":"112","author":"Li","year":"2011","journal-title":"J.
