CrossTORC and WNTegration in Disease: Focus on Lymphangioleiomyomatosis

Area of Science:

• Molecular Biology
• Cellular Biology
• Oncology

Background:

• The mechanistic target of rapamycin (mTOR) and wingless-related integration site (Wnt) pathways are evolutionarily conserved signaling networks regulating mammalian growth and cellular development.
• These pathways are frequently dysregulated in various diseases, including cancer, and are implicated in drug resistance and stem cell exhaustion.

Purpose of the Study:

• To review the key proteins and crosstalk between mTOR and Wnt signaling pathways.
• To discuss the role of these interactions in cancer development, drug resistance, and stem cell exhaustion.
• To highlight lymphangioleiomyomatosis (LAM) as a disease model involving TSC mutations and mTOR hyperactivity.

Main Methods:

• Literature review of key proteins and signaling crosstalk.
• Analysis of the role of mTOR and Wnt pathways in disease pathogenesis.
• Summary of current and potential therapeutic strategies targeting these pathways.

Main Results:

• Detailed description of intra- and extracellular crosstalk between mTOR and Wnt pathways.
• Elucidation of the involvement of these pathways in cancer, drug resistance, and stem cell exhaustion.
• Discussion of LAM as a specific example of mTOR pathway dysregulation.

Conclusions:

• Targeting mTOR and Wnt pathways offers therapeutic potential for various cancers and related conditions.
• Combination therapies and novel treatment strategies are being developed to overcome resistance.
• Further research into pathway crosstalk is essential for advancing treatment options.
