Insights

Natural products and phytochemicals show promise as cancer chemopreventive agents by selectively inducing apoptosis, a key mechanism in cancer therapy. This review explores how these compounds target cancer cells to inhibit tumor development.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Pharmacology

Background:

  • Cancer chemopreventive agents target carcinogenesis, acting via antioxidant, anti-inflammatory, or molecular targeting mechanisms.
  • Apoptosis, or programmed cell death, is a crucial cellular process with distinct morphological changes, increasingly utilized in novel anticancer therapies.
  • Plants have a long history in health management, with recent research highlighting diverse phytochemicals and botanical formulations with anticancer potential.

Purpose of the Study:

  • To review the literature on natural products and phytochemicals as cancer chemopreventive agents.
  • To elucidate the mechanisms by which these natural compounds induce apoptosis in cancer cells.
  • To highlight the potential of natural products in combating cancer.

Main Methods:

  • Literature survey of scientific publications on natural products, phytochemicals, and cancer chemoprevention.
  • Analysis of studies detailing the induction of apoptosis by natural compounds in cancer cells.
  • Synthesis of data on the molecular targets and mechanisms involved in phytochemical-induced apoptosis.

Main Results:

  • Natural products and diverse phytochemicals have been identified as agents capable of inducing apoptosis in cancer cells.
  • These compounds exhibit chemopreventive properties by inhibiting, reversing, or delaying carcinogenesis.
  • Mechanisms include antioxidative, antimutagenic/antigenotoxic, and anti-inflammatory actions, as well as direct targeting of cellular pathways.

Conclusions:

  • Natural products represent promising candidates for developing novel anticancer therapies due to their ability to induce apoptosis.
  • Phytochemicals offer a viable strategy for cancer chemoprevention through targeted induction of cancer cell death.
  • Further research into natural products can lead to the development of effective and selective anticancer agents.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized...

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Caspases01:24

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...
