Summary
Cancer cells disable apoptosis, a cellular suicide process, through altered metabolism. This review explores how glucose and lipid metabolism changes in cancer impact apoptosis signaling pathways.
Area of Science:
- Cellular biology
- Cancer research
- Metabolic pathways
Background:
- Apoptosis, or programmed cell death, is crucial for development and preventing diseases like cancer.
- Cancer cells evade apoptosis, promoting uncontrolled growth, survival, and treatment resistance.
- Metabolism is increasingly recognized as a key factor in cancer cells' evasion of apoptosis.
Purpose of the Study:
- To review the regulation of cellular apoptosis.
- To examine how cellular metabolism influences apoptosis signaling pathways.
- To focus on altered glucose and lipid metabolism in cancer and their impact on apoptosis.
Main Methods:
- Literature review of apoptosis regulation.
- Analysis of metabolic influence on apoptotic signaling.
- Focus on glucose and lipid metabolism alterations in cancer cells.
Main Results:
- Metabolites can modulate the function of proteins involved in apoptosis.
- The p53 protein regulates both apoptosis and cellular metabolism.
- Dysregulated metabolism and p53 inactivation equip cancer cells to evade apoptosis.
Conclusions:
- Altered cellular metabolism is a significant mechanism by which cancer cells evade apoptosis.
- Understanding the interplay between metabolism and apoptosis is vital for cancer therapy.
- Targeting metabolic pathways may offer new strategies to restore apoptosis in cancer cells.

01:31The Intrinsic Apoptotic Pathway
9.1K
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...

16.6K
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...

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.

01:17The Extrinsic Apoptotic Pathway
9.2K
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...

5.0K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
