Summary
Toxic metals like arsenic, chromium, and vanadium can cause disease via cell damage. This review explores how these carcinogenic metals induce cell death, possibly involving reactive oxygen species.
Area of Science:
- Environmental toxicology
- Molecular toxicology
- Biochemistry
Background:
- Toxic metals in the environment and workplace are linked to human diseases like cancer.
- Exposure can lead to DNA damage, protein modification, and lipid peroxidation.
- Carcinogenic metals are a significant public health concern.
Purpose of the Study:
- To review the mechanisms of cell death induced by specific carcinogenic metals.
- To discuss the role of reactive oxygen species in metal-induced cytotoxicity.
Main Methods:
- Literature review of existing studies on metal toxicity and cell death.
- Analysis of biochemical pathways involved in metal-induced cellular damage.
- Focus on arsenic (III), chromium (VI), and vanadium (V).
Main Results:
- Carcinogenic metals induce cell death through various mechanisms.
- DNA damage, protein modification, and lipid peroxidation are key pathways.
- Reactive oxygen species may play a crucial role in mediating metal toxicity.
Conclusions:
- Understanding metal-induced cell death mechanisms is vital for disease prevention.
- Further research into reactive oxygen species' role could reveal therapeutic targets.
- Mitigating exposure to toxic metals is essential for public health.

01:30Apoptosis
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.
01:17The 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...
01:31The 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...
01:17Phagocytosis 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.

01:25Mutagenicity and Carcinogenicity
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
01:22Cellular 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...
