Abstract:
Non-small cell lung cancer (NSCLC) accounts for 80-85% of all lung cancers, which has the highest cancer-related mortality worldwide. Regardless of the therapeutic effects of chemotherapy or targeted therapy, drug resistance will occur after 1 year. Heat shock proteins (HSPs) are a class of molecular chaperones participated in protein stability and multiple intracellular signaling pathways. It has been widely reported that HSPs family is over expressed in non-small cell lung cancer, and these molecules are also associated with protein stability and multiple intracellular signaling pathways. The effect of chemotherapy drugs or targeted drugs on cancer cells is usually to induce apoptosis. It is necessary to explore the interaction between heat shock protein family and apoptosis pathway in NSCLC. Here we provide a brief review of how HSPs affect the apoptotic pathway in NSCLC.
Insights
Heat shock proteins (HSPs) are overexpressed in non-small cell lung cancer (NSCLC), contributing to drug resistance. This review explores how HSPs impact apoptosis pathways in NSCLC, offering insights into overcoming treatment resistance.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality globally.
- Acquired resistance to chemotherapy and targeted therapy limits treatment efficacy in NSCLC.
- Heat shock proteins (HSPs) are molecular chaperones involved in protein homeostasis and cellular signaling, often overexpressed in cancers.
Purpose of the Study:
- To review the role of heat shock proteins (HSPs) in non-small cell lung cancer (NSCLC).
- To investigate the interaction between the HSP family and apoptosis pathways in NSCLC.
- To provide insights into potential therapeutic strategies targeting HSPs to overcome drug resistance in NSCLC.
Main Methods:
- Literature review of studies on HSPs, apoptosis, and NSCLC.
- Analysis of the molecular mechanisms by which HSPs influence apoptosis.
- Synthesis of current knowledge on HSPs' role in chemoresistance and targeted therapy resistance.
Main Results:
- HSPs are frequently overexpressed in NSCLC and are implicated in resistance to apoptosis induced by cancer therapies.
- Specific HSPs may modulate apoptosis through various signaling pathways, affecting cell survival and death.
- Understanding HSP-mediated apoptosis regulation is crucial for developing novel therapeutic approaches.
Conclusions:
- Heat shock proteins play a significant role in the progression and treatment resistance of NSCLC.
- Targeting HSPs or their interactions with apoptosis pathways presents a promising strategy for improving NSCLC outcomes.
- Further research into HSP function in NSCLC apoptosis is warranted to develop effective therapies.
