Insights

Electroporation-induced fusion transfers apoptotic signals from anoikis-induced cells to healthy cells. This fusion process may offer a new strategy for targeted cell deletion in cancer therapy.

Area of Science:

  • Cell Biology
  • Apoptosis Research
  • Cancer Therapeutics

Background:

  • Anoikis, a form of apoptosis triggered by matrix detachment, plays a role in normal tissue homeostasis.
  • Understanding how apoptotic signals propagate is crucial for developing targeted cell death strategies.

Purpose of the Study:

  • To investigate if apoptotic signals can be transferred from anoikis-induced cells to healthy cells via electroporation-induced fusion.
  • To explore the potential of this cell fusion mechanism for cancer treatment.

Main Methods:

  • Madin-Darby Canine Kidney (MDCK) cells were induced into anoikis and stained with FITC-annexin.
  • Viable MDCK cells were labeled with fluorescent beads.
  • Both cell populations were subjected to electroporation for fusion.
  • Flow cytometry was used to analyze cell viability, apoptosis, and fusion events.

Main Results:

  • Electroporation significantly increased the fusion of viable cells with apoptotic cells by 49-fold.
  • Fused cells (apoptotic-viable) showed an 8-fold higher likelihood of non-adherence and a 2.3-fold lower proliferation rate compared to controls.
  • Apoptotic signals were successfully transferred through cell fusion.

Conclusions:

  • Cell-to-cell transfer of apoptotic signals is achievable through electrofusion.
  • This mechanism presents a potential novel approach for targeted cell deletion in cancer treatment strategies.

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.
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...
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.
Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
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...
Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...
