KLF4 in cancer chemoresistance: molecular mechanisms and therapeutic implications

Area of Science:

• Oncology
• Molecular Biology
• Cancer Research

Background:

• Chemoresistance is a primary cause of cancer treatment failure and disease progression.
• The transcription factor Krüppel-like factor 4 (KLF4) is increasingly recognized for its role in cancer.
• Understanding KLF4's function is crucial for overcoming therapeutic resistance.

Purpose of the Study:

• To review the multifaceted role of KLF4 in mediating cancer chemoresistance.
• To elucidate the molecular mechanisms by which KLF4 contributes to drug resistance.
• To explore potential therapeutic strategies targeting KLF4-driven chemoresistance.

Main Methods:

• Literature review of studies investigating KLF4 in cancer chemoresistance.
• Analysis of KLF4's involvement in drug efflux, DNA repair, apoptosis, and stemness.
• Examination of KLF4 post-translational modifications (PTMs) in different cancer types.

Main Results:

• KLF4 modulates key processes including drug efflux, DNA repair, apoptotic signaling, tumor heterogeneity, and cancer cell stemness.
• Tissue-specific post-translational modifications of KLF4 significantly influence chemoresistance.
• KLF4 integrates diverse signaling pathways to promote a resistant phenotype.

Conclusions:

• KLF4 is a critical determinant of chemoresistance through various cellular mechanisms.
• Targeting KLF4 and its regulatory networks presents a promising strategy for overcoming treatment resistance.
• Further research into KLF4-mediated resistance mechanisms can lead to more effective cancer therapies.
