Insights

Apoptosis involves proteins moving between the nucleus and cytoplasm. This review explores nucleocytoplasmic transport of apoptosis factors and its role in cell death signaling.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Genetics

Background:

  • The nucleus is a primary target for DNA damage, a key trigger for apoptosis.
  • Apoptosis requires coordinated signaling between the nucleus and cytoplasm.
  • Nucleocytoplasmic transport is crucial for regulating cell death.

Purpose of the Study:

  • To review current knowledge on nucleocytoplasmic trafficking of apoptosis-related proteins.
  • To discuss the impact of apoptosis induction on nuclear transport.
  • To propose nuclear transport as a control point in apoptosis signaling.

Main Methods:

  • Literature review of studies on apoptosis and nucleocytoplasmic transport.
  • Analysis of protein migration patterns during apoptosis.
  • Discussion of regulatory mechanisms of nuclear transport in cell death.

Main Results:

  • Diverse pro-apoptotic factors shuttle between cytoplasm and nucleoplasm.
  • DNA damage signals propagate via nucleocytoplasmic transport.
  • Apoptosis induction affects the nuclear transport machinery.

Conclusions:

  • Nucleocytoplasmic transport is integral to the apoptotic program.
  • Nuclear transport machinery is modulated during apoptosis.
  • Nuclear transport may serve as a critical control point in apoptotic signaling.

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.
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.
Nuclear Protein Sorting01:34

Nuclear Protein Sorting

Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...
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...
Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...
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...
