Adult male SD rats were treated separately with natural saline (NS), lipopolysaccharide (LPS, 5 mg\/kg), DBDCT (1.25, 2.5 and 5.0 mg\/kg) intraperitoneally for 2 days after induction of CYP3A with dexamethasone (DEX, 100 mg\/kg) for 4 days. Western blot analysis and fluorescent quantitation PCR (FQ-PCR) were conducted to determine the changes in expression of CYP3A, PXR, CAR and RXR. The biological accumulation of DBDCT and total Sn were determined by high-performance liquid chromatography (HPLC) and atomic fluorescence spectrometry (AFS). CYP450 content and CYP3A activities were significantly inhibited (p &lt; 0.05) in DBDCT-treated rats compared with the control group, as was the expression of CYP3A (p &lt; 0.05) at both protein and mRNA levels. In DBDCT-treated groups, the expression of PXR protein and mRNA increased, while the expression of CAR decreased. The biological accumulation of DBDCT and Sn in rat livers treated with DBDCT was high. The accumulation of DBDCT and Sn due to the inhibition of CYP3A may be involved in the mechanism of toxicity of DBDCT in rat liver.<\/jats:p>","DOI":"10.3390\/molecules170910994","type":"journal-article","created":{"date-parts":[[2012,9,12]],"date-time":"2012-09-12T12:11:41Z","timestamp":1347451901000},"page":"10994-11009","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Inhibition of Cytochrome P450 3A in Rat Liver by the Diorganotin (IV) Compound di-n-Butyl-di-(4-chlorobenzo-hydroxamato)tin (IV) and Its Probable Mechanism"],"prefix":"10.3390","volume":"17","author":[{"given":"Yunxia","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Pharmaceutical Science, Shanxi Medical University, 56 Xinjian South Road, Taiyuan 030001, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunlan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Pharmaceutical Science, Shanxi Medical University, 56 Xinjian South Road, Taiyuan 030001, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingshan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Pharmaceutical Science, Shanxi Medical University, 56 Xinjian South Road, Taiyuan 030001, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,9,12]]},"reference":[{"key":"ref_1","first-page":"54","article-title":"Progress in the study of metallic compounds on antitumor activity","volume":"4","author":"Yin","year":"1999","journal-title":"Chem.
