Targeting Signaling Pathway by Curcumin in Osteosarcoma.

Area of Science:

• Oncology
• Molecular Biology
• Pharmacology

Background:

• Osteosarcoma is the most common bone cancer in children and adolescents, with high mortality due to lung metastasis.
• Current treatments like chemotherapy and surgery have limited success, necessitating novel therapeutic strategies.
• Curcumin, a compound from Curcuma longa, exhibits anti-cancer properties and has shown potential in inhibiting osteosarcoma cell proliferation and inducing apoptosis.

Approach:

• This review summarizes the effects of curcumin on signaling pathways crucial to osteosarcoma pathogenesis.
• It explores curcumin's potential in targeting pathways such as MAPK/ERK, PI3k/AKT, Wnt/β-catenin, Notch, and microRNAs.
• The review also addresses the challenges of curcumin's hydrophobicity and poor bioavailability in clinical applications.

Key Points:

• Curcumin's ability to modulate multiple signaling pathways offers a multi-targeted approach for osteosarcoma treatment.
• In vitro studies suggest curcumin can inhibit osteosarcoma cell proliferation and promote apoptosis.
• Understanding these molecular mechanisms is vital for developing new therapeutic interventions.

Conclusions:

• Curcumin demonstrates significant potential as an anti-cancer agent for osteosarcoma by targeting critical signaling pathways.
• Overcoming curcumin's poor bioavailability and hydrophobicity is crucial for its clinical translation.
• Further research, including clinical trials, is warranted to establish curcumin's efficacy and safety in osteosarcoma treatment.
