Abstract:
:Cisplatin-induced heart damage is associated with enzymes and protein alterations. The purpose of this study was to investigate cisplatin-induced alterations in cardiac endothelin (ET)-1 and type III collagen following administration of cisplatin. Male Wistar rats were randomly divided into two groups: a control and a cisplatin group. The cisplatin group received cisplatin intraperitoneally (i.p.) at a single dose of 7 mg/kg on day 6, while the controls were given the same amount of saline via the same route. On day 11, the rats were anesthetized and a thoracotomy was performed on all animals. Immunohistochemical analysis was performed to evaluate the protein expression of ET-1 and type III collagen. Sections were analyzed by digital image analysis. Results showed that the cardiac protein expression of ET-1 and type III collagen was altered following cisplatin-induced toxicity in rats. The expression of ET-1 and type III collagen was significantly increased after cisplatin treatment, supported by integrated optical density, when compared to the control group (P<0.05). The present findings indicate that such alterations may be reflected in abnormal cardiac function. Additionally, the proteins identified in this study may benefit investigations into the mechanisms underlying cisplatin-induced toxicity, thereby providing the necessary evidence for further research.
