Autophagy-related myosins: Critical roles and potential therapeutic effects in malignancies

Area of Science:

• Molecular Biology
• Cell Biology
• Cancer Research

Background:

• Myosins are actin-based motor proteins crucial for cellular functions and actin cytoskeleton remodeling.
• Myosins act as mechano-sensors in the tumor environment, influencing tumorigenesis and cell activities like migration and signaling.
• Autophagy is vital for cellular homeostasis, involving cargo transport to lysosomes for degradation.

Purpose of the Study:

• To review the multifaceted roles of myosins in autophagy.
• To explore how myosins mediate autophagy's involvement in cancer development and progression.
• To provide new perspectives on therapeutic strategies targeting myosin-mediated autophagy in tumors.

Main Methods:

• Literature review and synthesis of existing research findings.
• Dissection of myosin functions across different autophagy stages.
• Analysis of myosin-autophagy interplay in the tumor microenvironment.

Main Results:

• Myosins play diverse roles throughout the autophagy process.
• Myosin-mediated autophagy significantly impacts cancer development and progression.
• Evidence highlights the connection between myosins, autophagy, and tumor microenvironment-associated immune cells.

Conclusions:

• Myosins are key regulators of autophagy in the context of cancer.
• Targeting myosin-autophagy pathways presents potential therapeutic avenues for cancer treatment.
• Further research into myosin functions in autophagy could unlock novel anti-cancer strategies.
