Evaluation of the Anti-melanogenic Effect of Aqueous and Hydroalcoholic Extracts of Nasturtium Officinale on the B16F10 Cell Line Mohaddese Heydari, Masoud Sadeghi-Dinani, Fatemeh Shafiee Avicenna Journal of Medical Biotechnology, 2026 Background: This project aimed to evaluate the anti-melanogenic characteristics of Nasturtium officinale (N. officinale) by assessing the impact of both aqueous and hydroalcoholic extracts on the inhibition of cellular and mushroom tyrosinase enzymes, as well as the suppression of the melanin synthesis in B16F10 melanoma cells.Methods: The aerial components of N. officinale were subjected to extraction using distilled water: ethanol (7:3) through the maceration technique. The extract’s phenolic compounds were quantified employing the Folin-Ciocalteu method. The evaluation of the safety profile of the extracts on B16F10 cells was done by the MTT assay. Subsequently, the melanin concentration in B16F10 cells, alongside the inhibitory effects on both mushroom and cellular tyrosinase, was assessed following treatment with the aforementioned extracts.Results: The aqueous and hydroalcoholic extracts exhibited no significant toxicity on B16F10 when compared to Phosphate-Buffered Saline (PBS). Additionally, there was no notable difference in the cytotoxic effects of extracts on the B16F10 cell line. Both extracts resulted in inhibition of cellular and mushroom tyrosinase, along with a decrease in melanin levels in B16F10 in a concentration-dependent manner. Ultimately, the total phenolic content in the aqueous and hydroalcoholic extracts was found to be approximately 14 and 30 mg/g of gallic acid, respectively.Conclusion: This in vitro investigation offers evidence supporting the skin brightening properties of N. officinale as an anti-melanogenic agent. Given its safety profile and absence of toxic effects on melanoma cells, it may be incorporated into the formulation of skin-brightening products following preclinical tests.
Preparation of Pluronic F127 hydrogel loaded with BIF1-iRGD recombinant protein for its targeted anti-cancer effects Zahra Tamizifar, Abbas Jafarian-Dehkordi, Somayeh Taymouri, Fatemeh Shafiee Research in Pharmaceutical Sciences, 2025 Background and purpose: Pluronic F127-based hydrogel is a fair formulation for increasing the protein stability and half-life without decreasing its biological activity. The present study aimed to prepare FP127 hydrogel loaded with the recombinant BIF1-iRGD protein as a new immunotoxin with targeting potential of cancer cells. Experimental approach: BIF1-iRGD in 19% w/v of FP127 was prepared by the cold method, and its in vitro release was determined. MTT and flow-cytometry assays were performed to evaluate the cytotoxic and apoptotic effects of BIF1-iRGD and BIFl-iRGD-hydrogel against 4T1 cells. The tumor size of 4T1 Balb-C mice was evaluated, and H&E staining was used for histopathology evaluation. Findings/Results: BIFl-iRGD release followed the first-order model. The toxicity of BIFl-iRGD was less than that in the formulation as a hydrogel after 48 and 72 h of treatment. The null hydrogel showed no toxicity compared to the untreated cells. After 24 h, cells treated with BIFl-iRGD-hydrogel and BIFl-iRGD around their 48-h IC 50 value developed apoptosis at about 55% and 35%, respectively. The tumor size decreased over time in the treated mice during the 20 days after the last injection. Also, no significant difference was observed between the effectiveness of the two groups. Tumor sections of mice treated with BIF1-iRGD and BIF1-iRGD-hydrogel had necrotic parts of about 65% and 70%, respectively. Conclusion and implications: BIF-iRGD-hydrogel showed in vivo anticancer effects with increased toxicity in comparison to the native protein. However, the investigation of protein distribution and probable cytotoxic effect on vital organs must be noted.
Fractionation of Allium giganteum Effective Extract on Gastrointestinal Neoplasms Cell Lines for Its Anti-Proliferative Properties Masoud Sadeghi Dinani, Mohammadreza Ghanbarzadeh, Fatemeh Shafiee Advanced Biomedical Research, 2025 Background: This study was designed to investigate the various extracts of Allium giganteum in term of their cytotoxic effects on gastric and colon cancer cell lines and then fractionation of extract with the most desired effects on cancer cells in comparison to the normal cell line. Materials and Methods: The A. giganteum air-dried bulbs were extracted in four solvents including aqueous, butanol, chloroform: methanol (9:1), and dichloromethan extracts. Evaluating the cytotoxicity of extracts were done by MTT assay against HT-29, KATO-III, and HUVEC cell lines. The extract with The most cytotoxicity on cancer cells and lower toxicity on normal cell line was subjected to the fractionation by MPLC using a RP-18 silica gel column and in the next stage and the cytotoxicity of resulted fractions were determined by MTT assay. Results: Chloroform: methanol extract was the safest extract on HUVEC cells with great cytotoxic effects against cancer cell lines (IC50 17.3 and 23 µg/mL, for KATO-III and HT-29, respectively). The results of MTT assay for 7 fractions of the chloroform: methanol extract showed that 5th fraction (E) was the most cytotoxic fraction (IC50 9 and 11.2 µg/mL for HT-29 and KATO-III, respectively). TLC and NMR analysis of the fractions suggested the presence of steroidal saponins as the main constituents. Conclusion: Significant cytotoxic effects of Allium giganteum was established against GI cancer cell lines especially fractions rich in steroidal saponins. So, these fractions are attractive candidate for the isolation and identification of effective ingredients.
