Abstract
Some immortalized lens epithelial cell lines have been established and are useful for molecular analysis. The establishment of additional cell lines must, however, enable a variety of in-vitro examinations. The objective of this study was to establish a new canine lens epithelial cell line by isolating CLC-1 cells from the lens tissue of a dog with cataracts. In CLC-1 cells, transforming growth factor beta (TGF-β) treatment significantly decreased gene expression of an epithelial marker and elevated that of mesenchymal markers; these characteristics are similar to those of a human lens epithelial cell line. Interestingly, CLC-1 cells exhibited lower expression of an epithelial marker and higher expression of mesenchymal markers than an anterior lens capsule. These results suggest that CLC-1 cells were derived from a cell population that was committed to epithelial-mesenchymal transition in cataract lens tissue. In conclusion, CLC-1 cells could be useful for analyzing molecular pathogenesis in canine cataracts.

Animals (Basel) 2019; 9:ani9080559. [PMID: 31443255 PMCID: PMC6720897 DOI: 10.3390/ani9080559] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2019] [Revised: 08/02/2019] [Accepted: 08/10/2019] [Indexed: 11/25/2022] Open
Abstract
Simple Summary Manganese (Mn) supplementation is especially necessary to avian species because the absorption of dietary Mn is relatively inefficient in birds. Recently, there has been increasing interest in the use of organic Mn to replace inorganic Mn as dietary Mn supplements in poultry. This study compared the uptake of Mn from Mn-lysine complex (MnLys) and MnSO4 in the primary chicken intestinal epithelial cells when the Fe, N-ethylmaleimide (a transport system y+ inhibitor), or cycloheximide (a transport system b0,+ activator) added in the culture medium. The results revealed that the uptake of Mn from the MnLys complex not only might be transported through the ionized Mn2+ pathway, but also appeared to be transported through the transport systems y+ and b0,+ in the intestine of chickens. Abstract Organic manganese (Mn) sources can replace inorganic Mn as dietary Mn supplements in poultry. To compare the uptake of Mn from the Mn-lysine complex (MnLys) and MnSO4, we first established the primary chicken intestinal epithelial cells (IECs) model and used it to determine Mn uptake. The MnLys increased the uptake of Mn compared to MnSO4. The uptake of Mn decreased in the IECs with Fe addition in the medium regardless of the Mn sources. The MnLys decreased the Mn2+ efflux transporter ferroportin 1 (FPN1) mRNA level but did not influence the Mn2+ influx transporter divalent metal transporter 1 (DMT1) mRNA expression when compared to MnSO4. The results above indicated that the increase of Mn accumulation for MnLys at least partly was due to the decrease of Mn efflux by reduced FPN1 expression. The addition of N-ethylmaleimide, an L-lysine transport system y+ inhibitor, decreased the uptake of Mn from MnLys but did not affect the uptake of Mn from MnSO4. The cycloheximide, as an L-lysine transport system b0,+ activator, increased the uptake of Mn from MnLys, whereas they did not influence the uptake of Mn from MnSO4. The MnLys increased the system y+ members cationic amino acid transporter (CAT) 1 and CAT2, and system b0,+ components rBAT and b0,+AT mRNA expression when compared to MnSO4. These results suggested that the uptake of MnLys complex might be transported by CAT1/2 and system b0,+, which was different from the ionized Mn2+ uptake pathway. In conclusion, the uptake of Mn from MnLys complex not only might be uptake through the ionized Mn2+ pathway, but also appeared to be transported through the CAT1/2 and system b0,+ in primary chicken IECs.

Expression Profile of Cationic Amino Acid Transporters in Rats with Endotoxin-Induced Uveitis. Mediators Inflamm 2016; 2016:6586857. [PMID: 27413255 PMCID: PMC4927963 DOI: 10.1155/2016/6586857] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2016] [Accepted: 05/23/2016] [Indexed: 11/17/2022] Open
Abstract
Purpose. The transcellular arginine transportation via cationic amino acid transporter (CAT) is the rate-limiting step in nitric oxide (NO) synthesis, which is crucial in intraocular inflammation. In this study, CAT isoforms and inducible nitric oxide synthase (iNOS) expression was investigated in endotoxin-induced uveitis (EIU). Methods. EIU was induced in Lewis rats by lipopolysaccharide (LPS) injection. In the treatment group, the rats were injected intraperitoneally with the proteasome inhibitor bortezomib before EIU induction. After 24 hours, leukocyte quantification, NO measurement of the aqueous humor, and histopathological examination were evaluated. The expression of CAT isoforms and iNOS was determined by reverse transcription-polymerase chain reaction, western blotting, and immunofluorescence staining. Nuclear factor-kappa B (NF-κB) binding activity was evaluated by electrophoretic mobility shift assay. The mouse macrophage cell line RAW 264.7 was used to validate the in vivo findings. Results. LPS significantly stimulated iNOS, CAT-2A, and CAT-2B mRNA and protein expression but did not affect CAT-1 in EIU rats and RAW 264.7 cells. Bortezomib attenuated inflammation and inhibited iNOS, CAT-2A, and CAT-2B expression through NF-κB inhibition. Conclusions. CAT-2 and iNOS, but not CAT-1, are specifically involved in EIU. NF-κB is essential in the induction of CAT-2 and iNOS in EIU.
