Final answer:
Caspase interference with CAD can hinder apoptosis, potentially causing uncontrolled cell proliferation and cancer progression. Caspases activate CAD, leading to cellular auto-digestion, a critical part of programmed cell death. Disruption in caspase activity can affect cellular integrity and contribute to various diseases.
Step-by-step explanation:
The impact of caspase interference with CAD (Caspase-Activated DNase) involves the disruption of the cell's apoptotic process. Caspases are a family of proteases that play a critical role in programmed cell death. When active caspase is released, it can lead to the auto-digestion of the cell by triggering a cascade of events that will degrade the cellular components, including CAD which cleaves DNA, contributing to the cell's disassembly during apoptosis.For instance, if caspase interference occurs, this can prevent CAD from functioning properly, potentially delaying cell death processes or leading to uncontrolled cell proliferation, which in some cases can contribute to cancer. This is because the inhibition of RAS G-protein's GTPase activity would prevent the hydrolysis of GTP to GDP, leading to a constitutively active RAS protein and continuous cell growth signaling, contributing to cancer progression.Similarly, excitotoxicity due to calcium-permeable AMPA receptors can lead to disruption of cellular processes by uncontrolled calcium influx influencing cell death pathways. Mitigation techniques, such as employing BAPTA to chelate calcium or restoring ADAR2 enzymatic activity, can potentially help in reducing the negative effects of calcium-permeable AMPA receptors in neurodegenerative diseases like ALS.
