The TERT Promoter: A Key Player in the Fight for Cancer Cell Immortality.

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Telomeres and telomerase play significant roles in cellular aging and cancer progression.
• Dysregulation of telomerase is a hallmark of many cancers, enabling uncontrolled proliferation.

Purpose of the Study:

• To review the mechanisms of telomerase reverse transcriptase (TERT) expression activation in cancers, particularly CNS tumors.
• To explore the role of TERT gene promoter (TERTp) mutations in cancer development.
• To discuss the potential of TERTp mutational status as a prognostic biomarker.

Main Methods:

• Literature review of studies on telomeres, telomerase, and TERT gene promoter mutations.
• Analysis of TERTp structure and its interaction with transcription factors.
• Evaluation of TERTp mutations as prognostic markers in CNS malignancies and other cancers.

Main Results:

• Somatic mutations in the TERT gene promoter (TERTp) are a primary mechanism for activating TERT expression in various cancers.
• Specific transcription factors directly interact with TERTp, regulating its activity.
• TERTp mutations are frequently observed in CNS tumors and share common profiles with other malignancies.

Conclusions:

• TERT promoter mutations are a critical driver of TERT activation in cancer.
• Understanding TERTp structure and regulatory factors is essential for cancer research.
• TERTp mutational status holds promise as a prognostic marker for CNS tumors and other cancers.
