Apoptosis deregulation in myeloproliferative neoplasms
Einstein (Sao Paulo, Brazil)
|February 4, 2014
Summary
Philadelphia-chromosome negative myeloproliferative neoplasms involve genetic mutations like JAK V617F and dysregulated apoptosis. Understanding these mechanisms is key to developing new therapies for these blood cancers.
Area of Science:
- Hematology
- Molecular Biology
- Oncology
Background:
- Philadelphia-chromosome negative chronic myeloproliferative neoplasms (MPNs) are clonal hematologic disorders.
- The exact cellular and molecular mechanisms driving MPN pathophysiology remain unclear.
- Genetic alterations, including JAK V617F mutations, are implicated in MPN development.
Purpose of the Study:
- To review the alterations in apoptosis regulation in MPNs.
- To highlight the importance of understanding apoptosis deregulation for novel therapeutic strategies.
Main Methods:
- Literature review focusing on apoptosis regulation in MPNs.
- Analysis of genetic alterations and their role in MPN pathogenesis.
Main Results:
- Deregulation of apoptosis, involving pro- and anti-apoptotic gene expression, contributes to myeloid cell accumulation in MPNs.
- Resistance to apoptosis is a significant factor in the pathogenesis of these neoplasms.
Conclusions:
- Altered apoptosis regulation is a critical component in the development of MPNs.
- Further research into apoptosis mechanisms is essential for advancing MPN treatment options.

01:31The Intrinsic Apoptotic Pathway
6.2K
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...

01:01Regulation of Hematopoietic Stem Cells
3.4K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

02:23Abnormal Proliferation
4.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

01:30Apoptosis
12.0K
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...

01:17The Extrinsic Apoptotic Pathway
6.2K
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...

2.0K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...
