Dopamine receptor-mediated gene regulation relies on second messenger cascades that involve cyclic nucleotides to relay signaling from the synapse to the nucleus. Phosphodiesterases (PDEs) catalyze cyclic nucleotides and thus potently control cyclic nucleotide signaling. We investigated the role of the most abundant striatal PDE, PDE10A, in striatal gene regulation by assessing the effects of PDE10A inhibition (by a selective PDE10A inhibitor, TP-10) on gene regulation and by comparing the basal expression of PDE10A mRNA throughout the striatum with gene induction by dopamine agonists in the intact or dopamine-depleted striatum. Our findings show that PDE10A expression is most abundant in the sensorimotor striatum, intermediate in the associative striatum and lower in the limbic striatum. The inhibition of PDE10A produced pronounced increases in gene expression that were directly related to levels of local PDE10A expression. Moreover, the gene expression induced by L-DOPA after dopamine depletion (by 6-OHDA), or by psychostimulants (cocaine, methylphenidate) in the intact striatum, was also positively correlated with the levels of local PDE10A expression. This relationship was found for gene markers of both D1 receptor- and D2 receptor-expressing striatal projection neurons. Collectively, these results indicate that PDE10A, a vital part of the dopamine receptor-associated second messenger machinery, is tightly linked to drug-induced gene regulation in the striatum. PDE10A may thus serve as a potential target for modifying drug-induced gene regulation and related neuroplasticity.<\/jats:p>","DOI":"10.3390\/cells11142214","type":"journal-article","created":{"date-parts":[[2022,7,17]],"date-time":"2022-07-17T21:00:28Z","timestamp":1658091628000},"page":"2214","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Phosphodiesterase 10A (PDE10A): Regulator of Dopamine Agonist-Induced Gene Expression in the Striatum"],"prefix":"10.3390","volume":"11","author":[{"given":"Ryan","family":"Bonate","sequence":"first","affiliation":[{"name":"Stanson Toshok Center for Brain Function and Repair, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriela","family":"Kurek","sequence":"additional","affiliation":[{"name":"Stanson Toshok Center for Brain Function and Repair, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Hrabak","sequence":"additional","affiliation":[{"name":"Stanson Toshok Center for Brain Function and Repair, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Santanna","family":"Patterson","sequence":"additional","affiliation":[{"name":"Stanson Toshok Center for Brain Function and Repair, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5529-3168","authenticated-orcid":false,"given":"Fernando","family":"Padovan-Neto","sequence":"additional","affiliation":[{"name":"Discipline of Neuroscience, The Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony R.","family":"West","sequence":"additional","affiliation":[{"name":"Discipline of Neuroscience, The Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"},{"name":"Center for Neurodegenerative Disease & Therapeutics, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9139-1312","authenticated-orcid":false,"given":"Heinz","family":"Steiner","sequence":"additional","affiliation":[{"name":"Stanson Toshok Center for Brain Function and Repair, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"},{"name":"Discipline of Cellular and Molecular Pharmacology, The Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, IL 60064, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,16]]},"reference":[{"key":"ref_1","unstructured":"Steiner, H., and Tseng, K.Y.
