Emerging Roles of p53 Related lncRNAs in Cancer Progression: A Systematic Review

Area of Science:

• Molecular Biology
• Genetics
• Cancer Research

Background:

• The p53 protein is a critical tumor suppressor involved in DNA damage response, apoptosis, and senescence.
• p53 acts as a sequence-specific transcription factor, regulating numerous genes, including various noncoding RNAs (ncRNAs).
• Long noncoding RNAs (lncRNAs) are a class of ncRNAs with diverse regulatory functions in biological processes.

Purpose of the Study:

• To review the current understanding of the interplay between lncRNAs and the p53 signaling pathway.
• To elucidate the mechanisms by which lncRNAs affect gene expression within the context of cancer.
• To discuss the potential of p53-associated lncRNAs as cancer biomarkers and therapeutic targets.

Main Methods:

• Literature review of recent studies on lncRNAs and the p53 pathway.
• Analysis of emerging high-throughput sequencing data identifying novel lncRNAs.
• Synthesis of current knowledge on lncRNA-mediated gene regulation in cancer.

Main Results:

• lncRNAs are increasingly found to be associated with and influence the p53 regulatory network.
• Various mechanisms of lncRNA action on gene expression within the p53 pathway have been identified.
• Emerging evidence suggests a significant role for these interactions in cancer development and progression.

Conclusions:

• p53-associated lncRNAs represent a rapidly expanding area of research in oncology.
• These lncRNAs hold promise for development as novel biomarkers for cancer diagnosis.
• Targeting p53-associated lncRNAs may offer new therapeutic strategies for cancer treatment.
