PTEN, Longevity and Age-Related Diseases

Area of Science:

• Molecular Biology
• Oncology
• Genetics

Background:

• PTEN is a crucial tumor suppressor and longevity factor.
• Its functions are linked to cellular pathways regulating growth and survival.
• Dysregulation of PTEN is implicated in various diseases, including cancer.

Purpose of the Study:

• To provide an in-depth review of PTEN's molecular associations, mutations, and regulations.
• To elucidate PTEN's role in enhancing longevity.
• To discuss PTEN's involvement in caloric restriction, DNA damage defense, and tumor suppression.

Main Methods:

• Comprehensive literature review of recent PTEN research.
• Analysis of PTEN's interactions with other molecules.
• Examination of PTEN's regulatory mechanisms and mutations.

Main Results:

• PTEN plays a significant role in caloric restriction and antioxidative DNA damage defense.
• PTEN effectively suppresses tumor formation.
• PTEN's function can be compromised by mutations and the PI3K/AKT pathway.

Conclusions:

• PTEN is a key target for strategies aimed at increasing longevity.
• Understanding PTEN's complex regulatory network is vital for therapeutic interventions.
• Maintaining PTEN integrity is critical for preventing cancer and promoting healthy aging.
