Summary
Paraptosis, a unique cell death form, involves ER/mitochondria swelling and vacuolation. Researchers are developing paraptosis inducers as a novel cancer therapy strategy.
Area of Science:
- Cell Biology
- Biochemistry
- Oncology
Background:
- Paraptosis is an emerging programmed cell death (PCD) pathway.
- It is morphologically distinct from apoptosis, autophagy, necrosis, and pyroptosis.
- Characterized by endoplasmic reticulum (ER) and/or mitochondrial dilation and cytoplasmic vacuolation.
Purpose of the Study:
- To review the mechanisms of paraptosis.
- To summarize recent advancements in developing paraptosis inducers for cancer therapy.
Main Methods:
- Literature review of paraptosis mechanisms and inducers.
- Analysis of natural products, synthetic compounds, and existing drugs as paraptosis inducers.
- Examination of combination therapies involving paraptosis inducers.
Main Results:
- Paraptosis can be induced by various agents including natural products, synthetic compounds, and anticancer drugs.
- These inducers activate multiple pathways to trigger paraptosis in cancer cells.
- Paraptosis inducers are increasingly used in combination with other therapeutic strategies.
Conclusions:
- Paraptosis represents a promising alternative therapeutic strategy for cancer treatment.
- Further research into paraptosis mechanisms and inducers could lead to novel cancer therapies.

01:31The Intrinsic Apoptotic Pathway
9.0K
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...

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...

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

16.3K
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
9.1K
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...
