Insights

Tumor necrosis factor-like weak inducer of apoptosis (TWEAK) signaling via its receptor Fn14 promotes apoptosis in endometrial cancer cells. This pathway, with high Fn14 and low TWEAK, presents a novel therapeutic target for endometrial cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cellular Signaling

Background:

  • The TWEAK/Fn14 pathway is implicated in various human tumors.
  • This pathway regulates critical cellular functions like proliferation, survival, migration, apoptosis, and differentiation.
  • Its specific role in endometrial cancer development requires elucidation.

Purpose of the Study:

  • To investigate the role of the TWEAK/Fn14 pathway in human endometrial cancer development.
  • To analyze TWEAK and Fn14 expression levels in endometrial cancer tissues.

Main Methods:

  • Gene expression analysis of TWEAK and Fn14 in human endometrial cancer and normal tissues.
  • Assessment of TWEAK's effect on endometrial cancer cell viability and apoptosis induction.
  • Investigation of caspase pathway involvement in TWEAK-induced apoptosis.

Main Results:

  • TWEAK gene expression was significantly down-regulated in endometrial cancer specimens.
  • Fn14 gene expression was significantly up-regulated in endometrial cancer specimens.
  • TWEAK treatment induced apoptosis and decreased cell viability in endometrial cancer cells via caspase pathways.

Conclusions:

  • Endometrial cancers exhibit high Fn14 expression and potentially low local TWEAK production.
  • Activation of the TWEAK/Fn14 pathway promotes cancer cell apoptosis.
  • The TWEAK/Fn14 pathway represents a potential therapeutic target for human endometrial cancer.

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...
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...
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.
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...

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.
