Cytotoxicity and Apoptotic Effect of Chitosan Nanoparticles Containing Hydroalcoholic Extract of Physalis alkekengi on HT29 Cell Line
Authors
Abstract:
Background and purpose: In this study, we aimed to evaluate the anticancer activity of Physalis alkekengi extract encapsulated into chitosan nanoparticles on HT29 cell line. Materials and methods: The fruits of the P.alkekengi were collected from Kohgiluyeh Boyerahmad province in south-west of Iran and dried in a dark environment. Then, the hydroalcoholic extract of the plant was extracted by percolation and encapsulated into chitosan nanoparticles. The toxicity effect of three samples; chitosan alone, chitosan containing the extract and the extract of P.alkekengi was investigated using MTT assay. Finally, Annxin V/propidium iodide (PI) kit was used to study the apoptotic effect of samples. Results: According to the MTT assay, during 72 hours, the cytotoxicity effect of chitosan nanoparticles of 160 nm containing the extract increased significantly (P< 0.05). Moreover, the apoptosis assay indicated that chitosan nanoparticles containing the extract had more apoptotic effects than the extract alone (71% vs. 43%). Conclusion: P.alkekengi extract encapsulated into chitosan nanoparticles had more anticancer activity compared with that of the extract alone.

Background and aims Colorectal and breast cancers are among the most important causes of mortality in the world. In spite of several attempts, their treatment is yet faced with several problems. Therefore, identification of novel therapeutic approaches is needed. Anti-cancer effects of curcumin and miR-34a have been proposed in various studies. Regarding their pro-apoptotic effects in cancer c...

Background and Objective: The management of apoptotic cell death has been considered as a putative therapeutic strategy for cancer treatment. In the present study we investigated the putative pro-apoptotic effect of allicin, the main garlic organosulfur component with repeatedly claimed chemopreventive potency, on the human adenocarcinoma cell line HT29 as an apoptosis resistant cell line, i...

Background and Objective: Garlic has been known worldwide as a dietary constituent with many pharmacological effects. The present in vitro study was designed to investigate the putative anticancer effect of garlic extract on cancer cells, and if this effect was through apoptosis induction. Material and Methods: Human colon adenocarcinoma cells HT29 were treated with different doses (1, 5 a...

The aim of this study was to evaluate the effect of the carotenoidic saponified extract of Physalis alkekengi sepals (PA) towards the lipoxygenase (LOX) oxidation of linoleic acid. Lipoxygenase activity in the presence of carotenoids, standard and from extract, was followed by its kinetic behaviour determining the changes in absorption at 234 nm. The standard carotenoids used were β-carotene (β...
