Insights

Cancer cells evade apoptosis through genetic mutations and epigenetic changes. Epigenetic drugs targeting chromatin modifiers can restore apoptosis, offering new cancer therapy strategies.

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • Epigenetics

Background:

  • Cancer cells evade programmed cell death (apoptosis) via genetic mutations and epigenetic alterations.
  • Epigenetic modifications, including DNA and histone alterations, regulate genes involved in apoptosis.
  • Chromatin-modifying enzymes play a crucial role in these epigenetic changes.

Purpose of the Study:

  • To explore how epigenetic deregulation impacts apoptosis signaling in cancer.
  • To review the role of chromatin-modifying enzymes in apoptosis evasion.
  • To discuss the therapeutic potential of epigenetic drugs in modulating cancer cell apoptosis.

Main Methods:

  • Review of scientific literature on epigenetics and apoptosis.
  • Focus on the function of chromatin-modifying enzymes (DNMT, HMT, HDAC, BET).
  • Analysis of epigenetic drug mechanisms and their impact on apoptosis.

Main Results:

  • Epigenetic mechanisms are critical for cancer cells to evade apoptosis.
  • Chromatin-modifying enzymes are key regulators of apoptosis signaling pathways.
  • Epigenetic drugs demonstrate potential in re-sensitizing resistant cancer cells to apoptosis.

Conclusions:

  • Targeting epigenetic modifications offers a promising therapeutic avenue for cancer treatment.
  • Epigenetic drug interventions can overcome therapy resistance by inducing apoptosis.
  • Rewiring the cancer epigenome can lead to effective apoptotic cell death.

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

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...

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...

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...
