Abstract
Nicotine is one of several physiologically stable and active chemicals found in tobacco. The mechanism through which nicotine causes kidney damage is still obscure. As a result, the goal of this research was to investigate how oral nicotine intake can lead to kidney damage. Naturaly occurring superfood green algae are immense supplements help us using extra chemicals during cancer prevalence if the patient is exposed to nicotine. Hence, the mitigating role of Chlorella vulgaris extract (CVE) against nicotine-nephrotoxic impact in Ehrlich ascites carcinoma (EAC)-bearing mice was studied. For this purpose, four groups of Swiss female mice were assigned, nicotine group (NIC) (100 µg/ml/kg), CVE group (100 mg/kg), CVE + Nicotine, and a control group. Renal dysfunction was evaluated by estimating serum biomarkers ofrenal damage. The expression pattern of Nf-KB, MAPK, P53, and α7-nAchR, lipid peroxidation biomarker, and antioxidant enzyme activities were evaluated in kidney tissue. Also, micro-morphometric examination and apoptosis immunohistochemical reactivity of kidney tissue were applied. The obtained results indicated up-regulation of all estimated genes and oxidative stress. Moreover, a significant (P < 0.05) increment in the apoptotic marker Caspase-3 and declined BCL-2 proteins were recorded. In serum, a significant (P < 0.05) elevation of urea, creatinine, TNF-α, IL-1β, and Kim-1 were evident. Histological investigation reinforced the aforementioned data, revealing structural changes involving the tubules, glomeruli, and interstitium of mice kidneys. CVE may be a strong contender for protecting renal tissue damage since it reduces renal tissue injury and oxidative stress. Cancer patients who regularly use nicotine through direct smoking or second-hand exposure can benefit from CVE usage as a dietary supplement.
