Context:
The c-Jun NH2-terminal kinase (JNK) is a member of the mitogen-activated protein kinase super family. JNK can phosphorylate a number of activator protein-1 components, activating several transcription factors, and thus, JNK signaling pathway is being involved in several carcinogenic mechanisms.
Objective:
In this study, we have reviewed the recent updates of the association of JNK pathway with osteosarcoma (OS), which is one of the most common and aggressive bone malignancies.
Methods:
In this review, we have explored the databases like PubMed, Google Scholar, MEDLINE, etc., and collected the most relevant papers of JNK signaling pathway involved in the pathogenesis and therapeutics of OS.
Results:
Evidence showed that JNK is a master protein kinase that plays an important role in osteoblast proliferation, differentiation and apoptosis. Interesting reports showed that chemical JNK inhibitors reduce OS cell proliferation and metastasis. Many of the components of this pathway have now been identified and the application of JNK inhibitors has been proven to work in vivo in human and in animal models; however, JNK pathway has not been translated into clinical use.
Conclusion:
Therapeutic interventions of potent and selective inhibitors of JNK might provide promising therapeutic approaches for the treatment of OS, and could improve the survival rate and quality of life of OS patients.
Insights
The c-Jun NH2-terminal kinase (JNK) pathway is crucial in osteosarcoma (OS) development. JNK inhibitors show promise in preclinical models, suggesting potential therapeutic applications for this aggressive bone cancer.
Area of Science:
- Molecular Biology
- Oncology
- Biochemistry
Background:
- The c-Jun NH2-terminal kinase (JNK) is a mitogen-activated protein kinase involved in various cellular processes.
- JNK signaling is implicated in multiple carcinogenic mechanisms.
- Osteosarcoma (OS) is a common and aggressive bone malignancy.
Purpose of the Study:
- To review recent findings on the association between the JNK pathway and osteosarcoma.
- To explore the role of JNK signaling in OS pathogenesis and potential therapeutic strategies.
Main Methods:
- Comprehensive literature search of databases including PubMed, Google Scholar, and MEDLINE.
- Collection and analysis of relevant research papers on JNK signaling in OS.
- Review of studies on JNK pathway components and their involvement in OS.
Main Results:
- JNK plays a key role in osteoblast proliferation, differentiation, and apoptosis.
- Chemical JNK inhibitors have demonstrated efficacy in reducing OS cell proliferation and metastasis in preclinical studies.
- While JNK pathway components are identified and inhibitors show in vivo efficacy, clinical translation is pending.
Conclusions:
- Targeting the JNK pathway with potent and selective inhibitors may offer novel therapeutic strategies for osteosarcoma.
- JNK inhibition could potentially improve survival rates and quality of life for OS patients.
- Further research is needed to translate JNK inhibitor efficacy into clinical practice for osteosarcoma treatment.
