Summary
The pro-apoptotic Bax gene is crucial for eliminating misplaced germ cells during mouse development. Bax also plays a role in regulating neuronal migration and cell death in the central nervous system.
Area of Science:
- Developmental Biology
- Cell Death Mechanisms
- Neuroscience
Background:
- Embryonic development involves intricate regulation of cell proliferation, migration, survival, and death.
- Primordial germ cells in mice often fail to reach the genital ridges, leading to ectopic locations.
- The pro-apoptotic gene Bax (Bcl-2 associated X protein) is implicated in programmed cell death.
Purpose of the Study:
- To review the role of the Bax gene in programmed cell death of ectopic germ cells.
- To examine the involvement of Bax in neuronal migration and cell death within the central nervous system.
Main Methods:
- Studies utilizing Bax-null (Bax(-/-)) mice.
- Analysis of germ cell migration and survival.
- Investigation of neuronal migration in the cerebellum, olfactory bulb, and hippocampus.
Main Results:
- Bax deficiency prevents the programmed cell death of ectopic germ cells.
- Bax-null mice exhibit impaired and ectopic neuronal migration in specific brain regions.
- Evidence suggests Bax is a key factor in ectopic cell death during development.
Conclusions:
- The Bax gene is essential for clearing misplaced germ cells during development.
- Bax influences neuronal migration and cell death in the developing and adult brain.
- Bax represents a significant mechanism underlying ectopic cell death in multiple tissues.

01:31The 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...
01:22Cellular 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...
01:30Overview 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...

01:17The 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...
01:18Autophagic 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.

01:24Caspases
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.
