Summary
Mitogen-activated protein kinases (MAPKs) are vital for cell survival under stress. This review explores the complex and often controversial roles of MAPK pathways, including ERKs, JNKs, and p38-MAPKs, in regulating apoptosis, using mouse models.
Area of Science:
- Cellular biology
- Molecular signaling
- Stress response pathways
Background:
- Cells face constant environmental stress, necessitating complex survival decisions.
- Mitogen-activated protein kinases (MAPKs) are key signaling molecules involved in cellular stress responses.
- MAPK family members include extracellular signal-regulated kinases (ERKs), c-Jun N-terminal kinases (JNKs), and p38-MAPKs.
Purpose of the Study:
- To review the multifaceted roles of MAPKs in apoptosis regulation.
- To critically analyze the complex and sometimes contradictory findings regarding MAPK involvement in apoptosis.
- To highlight the significance of mouse genetic models in understanding MAPK functions.
Main Methods:
- Literature review focusing on MAPK signaling pathways.
- Analysis of data from mouse genetic models investigating stress responses and apoptosis.
- Critical evaluation of existing research on MAPKs and apoptosis.
Main Results:
- Initially, ERKs were linked to cell survival, while JNKs and p38-MAPKs were associated with stress-induced apoptosis.
- The regulation of apoptosis by MAPKs is more intricate and debated than previously understood.
- Mouse genetic models reveal diverse and context-dependent functions of MAPKs in apoptosis.
Conclusions:
- MAPKs play complex and varied roles in apoptosis, extending beyond simple pro- or anti-apoptotic functions.
- Understanding MAPK signaling in apoptosis is crucial for comprehending cellular responses to stress.
- Further research, particularly utilizing genetic models, is essential to fully elucidate MAPK functions in cell fate determination.

01:30Apoptosis
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.
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.
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...
01:31The 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...
01:07MAPK Signaling Cascades
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
01:22PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
