Abstract:
Bee venom (BV) (api-toxin) has been widely used in the treatment of some immune-related diseases, as well as in recent times in treatment of tumors. Several cancer cells, including renal, lung, liver, prostate, bladder, and mammary cancer cells as well as leukemia cells, can be targets of bee venom peptides such as melittin and phospholipase A2. The cell cytotoxic effects through the activation of PLA2 by melittin have been suggested to be the critical mechanism for the anti-cancer activity of BV. The induction of apoptotic cell death through several cancer cell death mechanisms, including the activation of caspase and matrix metalloproteinases, is important for the melittin-induced anti-cancer effects. The conjugation of cell lytic peptide (melittin) with hormone receptors and gene therapy carrying melittin can be useful as a novel targeted therapy for some types of cancer, such as prostate and breast cancer. This review summarizes the current knowledge regarding potential of bee venom and its compounds such as melittin to induce cytotoxic, antitumor, immunomodulatory, and apoptotic effects in different tumor cells in vivo or in vitro. The recent applications of melittin in various cancers and a molecular explanation for the antiproliferative properties of bee venom are discussed.
Insights
Bee venom (BV) shows anti-cancer potential by inducing cell death in various cancer types. Its peptides, like melittin, offer novel therapeutic strategies for tumors.
Area of Science:
- Oncology
- Immunology
- Pharmacology
Background:
- Bee venom (BV) is traditionally used for immune-related diseases.
- Recent research explores BV's efficacy in cancer treatment.
- Key BV components include melittin and phospholipase A2 (PLA2).
Purpose of the Study:
- To review the anti-cancer properties of bee venom and its compounds.
- To discuss the molecular mechanisms of BV's cytotoxic and apoptotic effects.
- To explore novel therapeutic applications of BV in oncology.
Main Methods:
- Literature review of in vivo and in vitro studies on bee venom and cancer.
- Analysis of melittin's role in activating cytotoxic pathways (e.g., PLA2, caspases).
- Investigation of targeted therapy approaches using melittin conjugates and gene therapy.
Main Results:
- Bee venom demonstrates cytotoxic and antitumor effects against various cancer cells (renal, lung, liver, prostate, breast, leukemia).
- Melittin induces cancer cell death via apoptosis and activation of specific enzymes.
- BV exhibits immunomodulatory properties relevant to cancer therapy.
Conclusions:
- Bee venom, particularly melittin, possesses significant anti-cancer potential.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
