Abstract

Insights

Isothiocyanates (ITCs) induce apoptosis in human liver cancer cells (HepG-2) by generating reactive oxygen species (ROS). This process disrupts mitochondrial membrane potential, leading to programmed cell death.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Oncology

Context:

  • Hepatocellular carcinoma (HCC) remains a significant global health challenge.
  • Isothiocyanates (ITCs) are natural compounds with demonstrated anticancer properties.
  • Understanding the molecular mechanisms of ITC-induced cancer cell death is crucial for therapeutic development.

Purpose:

  • To investigate the apoptosis-inducing effects of ITCs on human liver cancer cells (HepG-2).
  • To elucidate the underlying mechanism of ITC-induced apoptosis, focusing on reactive oxygen species (ROS) and mitochondrial function.

Summary:

  • ITCs significantly inhibited HepG-2 cell proliferation in a dose-dependent manner.
  • Treatment with ITCs led to increased ROS levels and decreased mitochondrial membrane potential (ΔΨm).
  • A significant increase in hypodiploid apoptotic cells was observed following ITC treatment, confirming apoptosis induction.

Impact:

  • This study reveals that ITCs trigger apoptosis in HepG-2 cells via ROS generation and mitochondrial dysfunction.
  • The findings provide a mechanistic basis for the potential use of ITCs as chemotherapeutic agents against liver cancer.
  • Further research into ITC derivatives could lead to novel targeted therapies for HCC.

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...
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 reduction of the tissue.
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...
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 by phagocytes.
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
