Exploring the context-dependent role of miR-744 as a prognostic, diagnostic, and therapeutic biomarker across different cancer types.

MicroRNAs are small non-coding RNAs that regulate gene expression and play crucial roles in cancer development and progression. Among them, microRNA-744 (miR-744) has attracted increasing attention due to its complex, context-dependent functions across various cancer types. Evidence indicates that miR-744 can serve either as an oncogene or a tumor suppressor, depending on the tumor type and cellular environment. This dual role is mediated through regulation of multiple target genes involved in key cellular processes, including proliferation, apoptosis, migration, invasion and drug resistance. This review explores the expression patterns of miR-744 in different cancers such as breast, prostate, colorectal, gastric, lung, and brain tumors. It also examines the molecular mechanisms by which it influences tumor biology. Particular emphasis is placed on the clinical significance of miR-744 in tumor progression, including its prognostic, diagnostic, and therapeutic potential as a biomarker. These insights will have supported by recent clinical and preclinical studies, while also considering its interactions with key signaling pathways such as Wnt/β-catenin, PI3K/AKT, and MAPK. Understanding the intricate, context-dependent functions of miR-744 is essential for developing effective miRNA-based interventions and improving patient outcomes. Continued research is necessary to clarify its tumor-specific roles and translate these insights into clinical applications.
