Abstract:
Drug resistance is a primary cause of chemotherapeutic failure; however, how this resistance develops is complex. A comprehensive understanding of chemotherapeutic resistance mechanisms may aid in identifying more effective drugs and improve the survival rates of patients with cancer. Insulin-like growth factor 1 receptor (IGF1R), a member of the insulin receptor family, has been extensively assessed for biological activity, and its putative contribution to tumor cell development and progression. Furthermore, researchers have attended to drugs that target IGF1R since IGF1R functions as a membrane receptor. However, how IGF1R participates in chemotherapeutic resistance remains unclear. Therefore, the present study described the IGF1R gene and its associated signaling pathways, and offered details of IGF1R-induced tumor chemoresistance associated with promoting cell proliferation, inhibition of apoptosis, regulation of ATP-binding cassette transporter proteins and interactions with the extracellular matrix. The present study offered additional explanations for tumor chemotherapy resistance and provided a theoretical basis of IGF1R and its downstream pathways for future possible chemotherapy treatment options.
Insights
Drug resistance in cancer chemotherapy is complex. This study details how the Insulin-like Growth Factor 1 Receptor (IGF1R) promotes chemoresistance by affecting cell growth, apoptosis, and drug transporters.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Drug resistance is a major challenge in cancer chemotherapy, leading to treatment failure.
- Understanding resistance mechanisms is crucial for developing more effective cancer therapies.
- The Insulin-like Growth Factor 1 Receptor (IGF1R) is implicated in tumor progression, but its role in chemoresistance is not fully understood.
Purpose of the Study:
- To elucidate the role of IGF1R in the development of chemotherapeutic resistance in cancer.
- To detail the molecular mechanisms by which IGF1R contributes to chemoresistance.
Main Methods:
- Review and synthesis of existing research on IGF1R signaling pathways.
- Analysis of IGF1R's involvement in key cellular processes related to chemoresistance.
Main Results:
- IGF1R promotes chemoresistance by enhancing tumor cell proliferation.
- IGF1R inhibits apoptosis, contributing to treatment failure.
- IGF1R influences the expression of ATP-binding cassette transporter proteins.
- IGF1R interacts with the extracellular matrix, impacting drug resistance.
Conclusions:
- IGF1R plays a significant role in mediating tumor chemoresistance through multiple mechanisms.
- Targeting IGF1R and its downstream pathways may offer novel therapeutic strategies for overcoming chemotherapy resistance.
