  <dc:description>&lt;p&gt;&lt;span&gt;The present study investigated&amp;nbsp;&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Gonadotropin-releasing_hormone"&gt;GnRH&lt;/a&gt;&lt;span&gt;&amp;nbsp;forms within the brain of a representative of the order Cypriniformes, the white sucker,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Catostomus commersoni,&lt;/i&gt;&lt;span&gt;&amp;nbsp;using HPLC, RIA, and&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Immunocytochemistry"&gt;immunocytochemistry&lt;/a&gt;&lt;span&gt;. Several&amp;nbsp;&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Immunoassay"&gt;immunoreactive&lt;/a&gt;&lt;span&gt;&amp;nbsp;(ir) GnRH forms were identified in the brain of the white sucker by&amp;nbsp;&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Chromatography"&gt;chromatography&lt;/a&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Radioimmunoassay"&gt;radioimmunoassay&lt;/a&gt;&lt;span&gt;, including ir-salmon GnRH, ir-lamprey GnRH-I and -III, and ir-chicken GnRH-II. Results from immunocytochemical studies were consistent with multiple GnRH forms distributed in different patterns, particularly for fibers. Neuronal perikarya containing ir-salmon GnRH and ir-lamprey-like GnRH were found laterally within the&amp;nbsp;&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Preoptic_area"&gt;preoptic area&lt;/a&gt;&lt;span&gt;&amp;nbsp;and rostral&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Hypothalamus"&gt;hypothalamus&lt;/a&gt;&lt;span&gt;. Cells containing exclusively ir-salmon GnRH appeared slightly more rostrally, but in the same region. Fibers containing ir-salmon GnRH and ir-lamprey-like GnRH were seen throughout the caudal telencephalon and extended into the&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Diencephalon"&gt;diencephalon&lt;/a&gt;&lt;span&gt;, toward the&amp;nbsp;&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Pituitary_gland"&gt;pituitary&lt;/a&gt;&lt;span&gt;. Fibers containing ir-chicken-II-like GnRH were also seen in the caudal telencephalon, but were concentrated more dorsally in the diencephalon. Within the pituitary, fibers containing ir-salmon GnRH and ir-lamprey-like GnRH entered the&amp;nbsp;&lt;/span&gt;&lt;a class="linkText" href="http://topics.sciencedirect.com/topics/page/Posterior_pituitary"&gt;neurohypophysis&lt;/a&gt;&lt;span&gt;, but differed in their destinations. Fibers containing ir-salmon GnRH remained within the neurohypophysis, while fibers containing ir-lamprey-like GnRH targeted adenohypophyseal tissue. These findings are consistent with the hypothesis that multiple GnRH forms with multiple functions exist within the brain and pituitary of teleosts and provide further evidence of a lamprey-like GnRH within an early evolved teleost species.&lt;/span&gt;&lt;/p&gt;</dc:description>
