A Bioligical Perspective on the role of miR-206 in Colorectal cancer

MicroRNAs (miRs) have emerged as pivotal regulators in the development and progression of colorectal cancer (CRC), and MicroRNA-206 (miR-206) has garnered attention as a potentially influential factor. However, the specific biological functions and complete mechanistic understanding of miR-206 in CRC remain largely uncharacterized. This study aims to bridge this research gap by providing a comprehensive analysis of miR-206's role in CRC. An exploration of the molecular mechanisms regulated by miR-206, its intricate interplay with target genes, and its significant impact on cellular processes highlights its potential utility as both a diagnostic marker and a therapeutic target. The significance of this research lies in potentially enabling the development of innovative therapeutic approaches, ultimately aiming to improve prognosis and survival rates in CRC patients by elucidating the functions of miR-206. Critical pathways, such as c-Met and PTEN/AKT, play crucial roles within the regulatory network of miR-206 in CRC and impact various cellular processes involved in CRC pathogenesis, metastasis, and treatment response. Understanding the complex interactions between miR-206 and key signaling pathways like c-Met and PTEN/AKT is crucial for understanding the underlying mechanisms driving CRC initiation and progression. This knowledge can inform the development of targeted therapeutic interventions, potentially leading to improved patient outcomes and advances in CRC management.

MicroRNAs and Apoptosis in Colorectal Cancer

Colorectal cancer (CRC) is the third leading cause of cancer death in the world, and its incidence is rising in developing countries. Treatment with 5-Fluorouracil (5-FU) is known to improve survival in CRC patients. Most anti-cancer therapies trigger apoptosis induction to eliminate malignant cells. However, de-regulated apoptotic signaling allows cancer cells to escape this signaling, leading to therapeutic resistance. Treatment resistance is a major challenge in the development of effective therapies. The microRNAs (miRNAs) play important roles in CRC treatment resistance and CRC progression and apoptosis. This review discusses the role of miRNAs in contributing to the promotion or inhibition of apoptosis in CRC and the role of miRNAs in modulating treatment resistance in CRC cells.
