Abstract:
Cholangiocarcinoma is a highly aggressive cancer with a dismal prognosis and limited resectability. Chemotherapy has demonstrated tremendous benefits for patients with advanced and inoperable cancer, but drug resistance poses a significant obstacle. Despite recent progress in cancer therapy, the mechanisms driving drug resistance are multifaceted and not completely comprehended. Non-coding RNA refers to RNA molecules that are endogenous and do not code for proteins. Particularly microRNAs, long non-coding RNAs, circular RNAs, are widely acknowledged to be involved in cancer initiation, proliferation, and metastasis. Recently, evidences suggests that abnormal expression of non-coding RNAs contributes to resistance to different type of cancer therapies in cholangiocarcinoma. This occurs via the rewiring of signaling pathways including the reduction of anticancer drugs, apoptosis, interaction between cholangiocarcinoma and tumor-infiltrating immune cells, and cancer stemness. Thus, our review aims to demonstrate the potential of targeting non-coding RNA to override drug resistance and summarize the molecular mechanisms of how non-coding RNA contributes to drug resistance in cholangiocarcinoma.
Insights
Non-coding RNAs drive cholangiocarcinoma (bile duct cancer) drug resistance by altering key cancer pathways. Targeting these non-coding RNAs offers a promising strategy to overcome treatment resistance in this aggressive cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cholangiocarcinoma (bile duct cancer) is aggressive with poor outcomes and limited treatment options.
- Chemotherapy resistance is a major challenge in managing advanced cholangiocarcinoma.
- Mechanisms of chemotherapy resistance are complex and not fully understood.
Purpose of the Study:
- To review the role of non-coding RNAs in cholangiocarcinoma drug resistance.
- To summarize the molecular mechanisms by which non-coding RNAs confer resistance.
- To highlight the therapeutic potential of targeting non-coding RNAs.
Main Methods:
- Literature review of studies on non-coding RNAs and cholangiocarcinoma.
- Analysis of molecular pathways involved in non-coding RNA-mediated drug resistance.
- Synthesis of evidence on targeting non-coding RNAs for overcoming resistance.
Main Results:
- Abnormal non-coding RNA expression is implicated in cholangiocarcinoma drug resistance.
- Non-coding RNAs affect drug uptake, apoptosis, immune cell interaction, and cancer stemness.
