Insights

Multiple myeloma (MM) is a cancer where plasma cells accumulate due to failed apoptosis. Understanding apoptosis pathways is key to treating MM and overcoming treatment resistance.

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Biology

Background:

  • Multiple myeloma (MM) involves malignant plasma cells in the bone marrow.
  • MM cell accumulation results from impaired apoptosis, a regulated cell death process.
  • Resistance to apoptosis is crucial in MM pathogenesis and treatment failure.

Purpose of the Study:

  • To review key concepts and recent studies on signaling pathways in MM.
  • To summarize the clinical significance of these pathways in MM.

Main Methods:

  • Review of scientific literature on MM, apoptosis, and signaling pathways.
  • Focus on extrinsic and intrinsic apoptosis pathways and their regulation.
  • Analysis of therapeutic modalities targeting apoptosis-related proteins in MM.

Main Results:

  • Apoptosis is executed via death receptor (extrinsic) and mitochondrial (intrinsic) pathways.
  • Mitochondria are central to the intrinsic pathway, targeted by radiation and chemotherapy.
  • MM therapies modulate Bcl-2 family proteins and apoptosis inhibitors, regulated by p53, NF-κB, and STAT factors.

Conclusions:

  • Dysregulation of apoptosis is central to multiple myeloma development and treatment resistance.
  • Targeting apoptosis signaling pathways offers therapeutic strategies for MM.
  • Further research into these pathways can improve clinical outcomes for MM patients.

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.
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...
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...
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...
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...
