mTOR signaling pathway and mTOR inhibitors in cancer: progress and challenges

Area of Science:

• Oncology
• Molecular Biology
• Cellular Biology

Background:

• The mammalian target of rapamycin (mTOR) signaling pathway regulates fundamental cellular processes including proliferation, autophagy, and apoptosis.
• Dysregulation of the mTOR pathway is linked to various diseases, notably cancer, where it is frequently activated.
• The pathway's role in tumor metabolism, gene transcription, protein synthesis, and immune cell differentiation makes it a significant target in oncology.

Purpose of the Study:

• To elucidate the role of the mTOR signaling pathway in tumor cell apoptosis, autophagy, growth, and metabolism.
• To review the latest research advancements concerning mTOR inhibitors in the context of cancer therapy.

Main Methods:

• This review synthesizes existing literature on the mTOR signaling pathway and its inhibitors.
• It focuses on studies investigating the pathway's impact on tumor cell biology and therapeutic strategies.

Main Results:

• The mTOR pathway significantly influences tumor cell proliferation, survival, and metabolic reprogramming.
• Emerging mTOR inhibitors are showing promise in clinical studies, often in combination therapies.
• Evidence suggests mTOR inhibitors can modulate tumor cell apoptosis and autophagy.

Conclusions:

• The mTOR signaling pathway is a critical regulator of tumor cell behavior and a key target for anti-cancer drug development.
• Ongoing research into novel mTOR inhibitors and combination therapies holds significant potential for improving cancer treatment outcomes.
