Insights

Combining HDAC inhibitors (HDACI) with TRAIL enhances cancer cell death. This strategy sensitizes tumors to TRAIL-induced apoptosis, offering a promising approach for novel cancer therapeutics.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Apoptosis induction is a key cancer therapy strategy.
  • TNF-related apoptosis-inducing ligand (TRAIL) selectively targets cancer cells.
  • Cancer cells often resist TRAIL-induced apoptosis, necessitating combination therapies.

Purpose of the Study:

  • To explore the synergistic effects of HDAC inhibitors (HDACI) and TRAIL in cancer treatment.
  • To understand the molecular mechanisms behind HDACI and TRAIL synergy.
  • To guide the development of novel, cancer-selective therapeutics.

Main Methods:

  • Review of recent advances in understanding HDACI and TRAIL interactions.
  • Analysis of molecular events underlying synergistic cancer cell death.
  • Discussion of translating research findings into therapeutic design.

Main Results:

  • HDAC inhibitors reverse aberrant epigenetic changes, sensitizing cancer cells to TRAIL.
  • Synergistic tumor cell death observed across various human cancers with HDACI and TRAIL combinations.
  • Understanding molecular interactions facilitates the design of targeted therapies.

Conclusions:

  • HDACI combined with TRAIL show significant promise for cancer therapy.
  • Epigenetic modulation via HDACI enhances TRAIL-mediated apoptosis in cancer cells.
  • Further research can lead to improved, selective cancer treatment strategies.

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...

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...
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.
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 cells.
Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
