The Effect of α-Tocopherol on the Reduction of Inflammatory Processes and the Negative Effect of Acrylamide

Protective effects of vitamin E against acrylamide-induced hepatotoxicity and nephrotoxicity from fetal development to adulthood: Insights into Akt/NF-κB and Bcl-xL/Bax signaling pathways

Acrylamide (ACR), a toxin present in fried and baked carbohydrate-rich foods, is known to cause liver and kidney damage. This study aimed to investigate the mechanisms of oxidative stress, inflammation, and apoptosis that contribute to liver and kidney damage induced by chronic administration of ACR. Additionally, the effectiveness of vitamin E in mitigating these toxic effects was examined. The study initially involved dividing 40 pregnant rats into four groups. After lactation, the research continued with male offspring rats from each group. The offspring rats were divided into Control, Vitamin E, ACR, and ACR + Vitamin E groups. Following ACR administration, liver and kidney function tests were performed on serum samples. Biochemical analyses, evaluation of inflammation markers, histopathological examination, and assessment of protein levels of Akt/IκBα/NF-κB, Bax, Bcl-xL, and Caspase-9 were conducted on liver and kidney tissues. The analysis demonstrated that ACR adversely affected liver and kidney function, resulting in oxidative stress, increased inflammation, and elevated apoptotic markers. Conversely, administration of vitamin E positively impacted these parameters, restoring them to control levels. Based on the results, the mechanism of ACR's action on oxidative stress and inflammation-induced liver and kidney damage may be associated with the activation of apoptotic markers such as Bax and Caspase-9, as well as the Akt/IκBα/NF-κB signaling pathway. Consequently, the protective properties of vitamin E establish it as an essential vitamin for the prevention or mitigation of various ACR-induced damages.

The CAM Model-Q&A with Experts

The chick chorioallantoic membrane (CAM), as an extraembryonic tissue layer generated by the fusion of the chorion with the vascularized allantoic membrane, is easily accessible for manipulation. Indeed, grafting tumor cells on the CAM lets xenografts/ovografts develop in a few days for further investigations. Thus, the CAM model represents an alternative test system that is a simple, fast, and low-cost tool to study tumor growth, drug response, or angiogenesis in vivo. Recently, a new era for the CAM model in immune-oncology-based drug discovery has been opened up. Although there are many advantages offering extraordinary and unique applications in cancer research, it has also disadvantages and limitations. This review will discuss the pros and cons with experts in the field.
