Background: Diosgenin, a steroidal saponin spotted as a primary ingredient in many traditional Chinese medicines, has sparked the attention of researchers owing to its multi-targeted cytotoxicity towards a multitude of cancers. Regrettably, its true potential was bounded by its impoverished physicochemical properties. In order to fully exploit its ability, we plan to fabricate diosgenin into nanoparticle by encapsulating with biodegradable polymer chitosan. Aim: The current research intends to uncover the therapeutic potency of diosgenin encapsulated chitosan nanoparticles (DG@CS-NP) on 7,12dimethylbenz(a)anthracene (DMBA) induced rat mammary carcinoma by optimizing biochemical and histopathological modifications via attenuating Aryl hydrocarbon receptor (AhR) - nuclear factor erythroid-derived 2-related factors (Nrf-2) signaling. Methodology: Breast cancer was induced with a single dose of DMBA (25 mg/kg b.wt). Orally supplied DG 10mg/kg b.wt. and DG@CS-NP 5 mg/kg b.wt to DMBA-induced tumor-bearing rats shortly after tumor onset. After the experimental period, biochemical and histopathological studies were performed using mammary tissue sections. Furthermore, architectural immunohistochemistry was used to reveal the expression of AhR and Nrf-2 in experimental rats. Additionally, diosgenin interactions with these proteins were also evidently confirmed by molecular docking analysis. Result: We noticed that there is an elevated level of lipid peroxidative marker, phase-I detoxification enzymes, total cholesterol (TC), phospholipids (PL), triglycerides (TG), and free fatty acids (FFA) with boosted AhR expressions as well as diminished levels of enzymatic and non-enzymatic antioxidants and Phase – II detoxification enzymes with downtrodden Nrf-2 expressions in the mammary tissues of DMBA-induced rats. On the other contrary, oral dosing of DG@CS-NP 5 mg/kg b.wt, dramatically reverted them to near-normal tiers. Interestingly, molecular docking analyses also corroborate these insights by highlighting diosgenin's significant interactions with AhR and Nrf-2 targets. Conclusion: As an outcome of our observations, we conclude that nano-encapsulation of diosgenin is a potent targeted therapeutic candidate posing a massive impact on breast cancer than plain diosgenin.

“…), promises to be a fruitful bioactive chief compound of interest for both prevention and therapy of BC. Its anti-BC potency has been evidenced via modulating critical molecular candidates associated with growth, differentiation, inflammation, apoptosis, and oncogenesis [17]. Absurdly, DG has minimal oral bioavailability owing to its impoverished solubility/high lipophilicity, which becomes a crucial barrier for operating as a successful therapeutic agent.…”

Objective: The central motive of this study is to explore the therapeutic impact of Diosgenin encapsulated Chitosan nanoparticles (DG@CS-NP) on mammary carcinogenesis in female Sprague Dawley rats via modulating hormonal status, cell proliferation, inflammatory responses, and Apoptosis. Methods: 7,12-dimethylbenz(a)anthracene (DMBA) was administered subcutaneously near the mammary gland (25 mg/kg b. wt) to provoke mammary tumor in female Sprague Dawley rats. Following the progress of a tumor, DMBA-induced tumor-bearing rats were medicated orally with 5 mg/kg b. wt of DG@CS-NP. Consequently, the expression of ER, PR, PCNA, Cyclin D1, NF-κB, TNF-α, Bcl-2, Caspases-3, and p53 in experimental rats were revealed via architectural immunohistochemistry. Further, Diosgenin interactions with these proteins were evidently confirmed by molecular docking analysis. Results: As a result, we noticed diminished levels of ER, PR, PCNA, Cyclin D1, NF-κB, TNF-α, and Bcl-2 expressions in DG@CS-NP medicated rats as well as with elevated levels of Caspases-3 and p53 expressions. In DMBA rats, the expressions were vice versa. Additionally, molecular docking analyses support these outcomes by highlighting the strong interaction between Diosgenin and breast cancer targets. Conclusion: These reports prove that DG@CS-NP imposes its therapeutic impact by hormonal adjustments, downregulating proteins involved in inflammation and cellular proliferation, and thereby promotes apoptosis by impeding apoptotic inhibitors.
