Abstract

Objective: To determine whether incubation of cruciate ligament cells with acetylsalicylic acid, carprofen, meloxicam, or robenacoxib provides protection against Apoptosis induced by sodium nitroprusside (SNP).

Sample: Explants of cranial (CCL) and caudal (CaCL) cruciate ligaments from eight 1-day-old Beagles.

Procedures: Primary cultures of CCL and CaCL cells were created via enzymatic dissociation of cruciate explants. Purified cell cultures were incubated for 2 hours without (controls) or with 1 of 3 concentrations of 1 of 4 NSAIDs (10, 100, or 200 μg of acetylsalicylic acid/mL; 0.1, 1, or 10 μg of carprofen/mL; 0.1, 1, or 10 μg of meloxicam/mL; or 0.1, 1, or 10 μg of robenacoxib/mL) and subsequently incubated for 18 hours with 1 of 3 concentrations of SNP in an attempt to induce mild, moderate, or severe cytotoxic effects. Cell viability and Apoptosis were analyzed via a cell proliferation assay and flow cytometry, respectively. Prostaglandin E(2) concentrations were measured via an ELISA.

Results: Cytoprotective effects of NSAIDs were dependent on the extent of SNP-induced Apoptosis and were greatest in CCL and CaCL cell cultures with moderate SNP-induced cytotoxic effects. Preincubation with an NSAID improved cell viability by 15% to 45% when CCL and CaCL cells were subsequently incubated with SNP. Carprofen (10 μg/mL) had the greatest cytoprotective effects for CCL and CaCL cells. Incubation with NSAIDs resulted in a nonsignificant decrease in PGE(2) production from SNP-damaged cells.

Conclusions and clinical relevance: Results indicated that carprofen, meloxicam, and robenacoxib may reduce Apoptosis in cells originating from canine cruciate ligaments.
