Özet
This study aimed to reveal the presence of reactive oxygen species (ROS)-induced lipid peroxidation and DNA damage in ovine pulmonary adenocarcinomas (OPA) by evaluating malondialdehyde (MDA) and 8-hydroxy-2-deoxyguanosine (8-OHdG) expressions by immunohistochemical and immunofluorescence methods. Lung tissue samples were collected from 26 sheep brought to the Pathology Department for routine diagnosis. Lung tissues were fixed in 10% neutral buffered formalin, following routine procedures tissues were stained with hematoxylin and eosin. Avidin-Biotin Peroxidase method was used as immunohistochemical staining. Indirect immunofluorescence method was applied to the sections. Tumoral cells showed acinar, papillary or mixed type patterns. Only 2 of 20 cases metastasized to regional lymph nodes. All OPAs were immune positive for Jaagsiekte Sheep Retrovirus Capsid Protein (JSRV CA), MDA and 8-OHdG. The control group was negative for JSRV CA, MDA and 8-OHdG expressions. Malondialdehyde and 8-OHdG immune positive cells were statistically increased in the OPA group compared to the control group. In conclusion, our results demonstrate that higher MDA and 8-OHdG expressions in sheep with OPA suggest that OPA may be closely related to lipid peroxidation and oxidative DNA damage.
