Insights

Yeast metacaspase YCA1 is involved in programmed cell death. Studying yeast cell death pathways, including metacaspases, can reveal insights into apoptosis mechanisms across eukaryotes.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Genetics

Background:

  • A metacaspase (YCA1) is linked to programmed cell death in yeast.
  • Overexpression of mammalian pro-apoptotic proteins induces yeast cell death, but mechanisms are unclear.
  • Cell cycle blocks or damage trigger apoptosis-like cell death in higher eukaryotes.

Purpose of the Study:

  • To investigate the role of fission yeast metacaspase in programmed cell death.
  • To understand the genetic pathways influencing cell death in yeast.
  • To gain insights into apoptosis mechanisms in all eukaryotic organisms.

Main Methods:

  • Genetic analysis of fission yeast.
  • Identification and characterization of metacaspase genes.
  • Comparative genomics of metacaspases.

Main Results:

  • A metacaspase with >40% identity to budding yeast Yca1 was found in fission yeast.
  • The specific role of this fission yeast metacaspase in programmed cell death is currently unknown.
  • Deletion of triacylglycerol synthesis genes in fission yeast induces cell death and apoptotic markers.

Conclusions:

  • Yeast metacaspases are potential mediators of programmed cell death.
  • Further research is needed to elucidate the function of fission yeast metacaspase.
  • Studying yeast cell death pathways offers valuable insights into eukaryotic apoptosis.

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...
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...
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.
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...
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...
Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
