Abstract:
Nasopharyngeal carcinoma (NPC) is one of the most common malignant tumours of the head and neck in Southeast Asia and southern China. The Phosphatidylinositol 3-kinase/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signalling pathway is involved in processes related to tumour initiation/progression, such as proliferation, apoptosis, metastasis, and drug resistance, and is closely related to the clinicopathological features of NPC. In addition, key genes involved in the PI3K/AKT/mTOR signalling pathway undergo many changes in NPC. More interestingly, a growing body of evidence suggests an interaction between this signalling pathway and microRNAs (miRNAs), a class of small noncoding RNAs. Therefore, in this review, we discuss the interactions between key components of the PI3K/AKT/mTOR signalling pathway and various miRNAs and their importance in NPC pathology and explore potential diagnostic biomarkers and therapeutic targets.
Insights
Nasopharyngeal carcinoma (NPC) involves the PI3K/AKT/mTOR pathway and microRNAs (miRNAs). Understanding their interactions offers potential diagnostic biomarkers and therapeutic targets for this head and neck cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Nasopharyngeal carcinoma (NPC) is a prevalent head and neck malignancy, particularly in Southeast Asia.
- The Phosphatidylinositol 3-kinase/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway is crucial in NPC development, affecting proliferation, apoptosis, metastasis, and drug resistance.
- Alterations in key genes within the PI3K/AKT/mTOR pathway are observed in NPC.
Purpose of the Study:
- To review the intricate interactions between the PI3K/AKT/mTOR pathway and microRNAs (miRNAs) in NPC.
- To elucidate the significance of these interactions in NPC pathology.
- To identify potential diagnostic biomarkers and therapeutic targets for NPC.
Main Methods:
- Literature review focusing on the PI3K/AKT/mTOR pathway and miRNAs in NPC.
- Analysis of existing research on gene expression and pathway dysregulation in NPC.
- Synthesis of evidence regarding miRNA involvement in NPC pathogenesis.
Main Results:
- The PI3K/AKT/mTOR pathway is frequently dysregulated in NPC, influencing key oncogenic processes.
- MicroRNAs (miRNAs) demonstrate significant interactions with components of the PI3K/AKT/mTOR pathway in NPC.
- Specific miRNA-pathway interactions are linked to NPC clinicopathological features.
Conclusions:
- The interplay between the PI3K/AKT/mTOR pathway and miRNAs is pivotal in nasopharyngeal carcinoma.
- Targeting these interactions presents promising avenues for novel diagnostic biomarkers and therapeutic strategies for NPC.
- Further research into these molecular mechanisms can advance NPC treatment and patient outcomes.
