Sidr Kashmiry honey and its fractions induced apoptosis in hepatocellular carcinoma in vitro

Abstract

Positive evidence for anticancer activities of honey is growing and the mechanism on how honey has anticancer characteristics is an area of great interest. Honey has been studied in various cancer cell lines for its ability to induce apoptosis, with several mechanisms of action being suggested. This study aims to evaluate the apoptotic activity of the non cytotoxic Sidr Kashmiry honey and its residue of successive fractionation as well as the cytotoxic chloroform-methanol and ethyl acetate fractions against hepatocellular carcinoma cells in vitro. Apoptosis was assessed by DNA fragmentation, diphenyl amine assay, and ultrastructure investigation. Micronuclei test was carried out to assess genotoxicity. Crude honey, residue, ethyl acetate and chloroform-methanol induced apoptosis, however, the residue and ethyl acetate caused high genotoxicity. Non cytotoxic Sidr Kashmiry honey and its cytotoxic chloroform-methanol fraction could be a powerful pro-apoptotic and non-genotoxic anticancer agent.

Unveiling the Antioxidant Therapeutic Functionality of Sustainable Olive Pomace Active Ingredients

“…In vitro and in vivo studies suggested that phenolic compounds from different dietary sources can play a key role to delay cancer development and progression through decreased cell proliferation, inactivation of carcinogens, angiogenesis inhibition, induction of cell cycle arrest and apoptosis and modulating immunity [51,52].…”

Valorization of Onion Waste by Obtaining Extracts Rich in Phenolic Compounds and Feasibility of Its Therapeutic Use on Colon Cancer

“…This includes a large number of polyphenol-rich extracts from plants as well as isolated pure compounds [38], and thus, covers almost all types of cancers including multiple drug resistant cases [39]. Likewise, polyphenols showed strong in vivo and in vitro anti-proliferative effects through decreasing cell proliferation, the inactivation of carcinogens, angiogenesis inhibition, the induction of cell cycle arrest and apoptosis and modulating immunity on various human cancer cells with few or no toxicity effects on normal cells [40][41][42].…”

Overview of the Antioxidant and Anti-Inflammatory Activities of Selected Plant Compounds and Their Metal Ions Complexes

“…Such a variety of compounds and the diversion of their molecular activities mean that they can be used in the treatment of almost any type of cancer, including cases of multi-drug resistance [ 92 ]. In vitro and in vivo studies suggest that polyphenols from various food sources may play a key role in delaying the development and progression of cancer by reducing cell proliferation, inactivating carcinogens, inhibiting angiogenesis, inducing cell cycle inhibition and apoptosis, and modulating the immune response [ 93 , 94 , 95 ].…”
