Abstract:
Most current anticancer therapies induce tumor cell death through apoptosis where its specific involved pathways are poorly understood. For example, for many DNA-damaging agents, the specific biochemical lesions (DNA adducts) are associated with the induction of apoptosis via the mitochondria death pathway. However, several of these DNA-damaging agents like cisplatin induce apoptosis through plasma membrane disruption, triggering the Fas death receptor pathway. In this review, we focus on the role of early plasma membrane events in cisplatin-induced apoptosis. Special attention is given to changes in plasma membrane fluidity, inhibition of NHE1 exchanger, activation of acid sphingomyelinase and their consequences on the Fas death pathway in response to cisplatin.
Insights
Cisplatin triggers cancer cell death via plasma membrane changes, not just DNA damage. This review explores how membrane fluidity, NHE1 inhibition, and acid sphingomyelinase activation impact the Fas pathway in cisplatin-induced apoptosis.
Area of Science:
- Biochemistry
- Cell Biology
- Pharmacology
Background:
- Apoptosis is a key mechanism in cancer therapy, but its pathways are not fully understood.
- DNA-damaging agents often induce apoptosis via mitochondrial pathways, but some, like cisplatin, utilize plasma membrane disruption.
- The Fas death receptor pathway is implicated in cisplatin-induced apoptosis.
Purpose of the Study:
- To review the early plasma membrane events involved in cisplatin-induced apoptosis.
- To highlight the role of plasma membrane alterations in triggering the Fas death pathway.
Main Methods:
- Literature review focusing on biochemical and cellular mechanisms.
- Analysis of studies investigating plasma membrane properties and signaling pathways.
Main Results:
- Cisplatin induces apoptosis through mechanisms involving plasma membrane disruption.
- Key early events include altered plasma membrane fluidity, inhibition of the NHE1 exchanger, and activation of acid sphingomyelinase.
- These events are linked to the activation of the Fas death pathway.
Conclusions:
- Early plasma membrane events are critical in cisplatin-induced apoptosis.
- Understanding these membrane-associated pathways can offer new therapeutic strategies for cancer treatment.
