Abstract

Cancer represents a global health burden characterized by high morbidity and mortality,underscoring the urgent demand for reliable, non-invasive biomarkers to enhance early detection,prognostication, and therapeutic monitoring. Circulating microRNAs (c-miRNAs) are short non-coding RNAs present in body fluids that have attracted attention as potential biomarkers, because of their stability, ease of detection, and close relationship with tumor biology. This review evaluates the diagnostic and prognostic potential of c-miRNAs and their integration into precision oncology. A systematic search was performed across PubMed, Scopus, and ScienceDirect for publications from 2010 to 2025 that investigated c-miRNAs in human body fluids in relation to diagnosis, prognosis, or treatment response. Twelve studies met the eligibility criteria, encompassing breast, lung, colorectal, and gallbladder cancers. Frequently dysregulated c-miRNAs, particularly miR-21, miR-155, miR-210, and Let-7a, demonstrated consistent associations with tumor detection, patient survival, and disease progression. Analytical platforms ranged from quantitative RT-PCR to advanced biosensor-based technologies, enabling sensitive and rapid quantification. Collectively, the evidence highlights c-miRNAs as non-invasive biomarkers capable of complementing conventional clinical tools. Their clinical adoption could reduce reliance on invasive tissue biopsies, support earlier and more accurate diagnosis, assist in tailoring patient-specific treatment strategies, and promote the broader implementation of precision medicine in cancer care.

Abstract

Hypoxia is a fundamental physiological and pathological condition that disrupts cellular homeostasis through the excessive generation of reactive oxygen species (ROS), leading to oxidative stress, inflammation, and organ dysfunction. The imbalance between ROS production and antioxidant defense mechanisms is a key contributor to cell injury and disease progression. This review aims to elucidate the molecular interactions among major redox-sensitive signaling pathways hypoxia-inducible factor 1 (HIF-1), nuclear factor kappa B (NF-κB), and nuclear factor erythroid 2-related factor 2 (Nrf2) in hypoxia-induced oxidative stress, and to highlight the therapeutic potential of natural antioxidants in modulating these pathways. Relevant literature published over the past five years (2020-2025) was systematically reviewed using databases including PubMed, Scopus, and ScienceDirect. The selected studies focused on molecular redox signaling, hypoxia-induced oxidative mechanisms, and the modulatory roles of natural phytochemicals such as Ficus carica bioactive compounds. Recent findings reveal that natural antioxidants regulate redox signaling by activating Nrf2-dependent antioxidant responses, suppressing NF-κB driven inflammation, and stabilizing HIF-1α under hypoxic conditions. Phytochemicals, particularly flavonoids and polyphenols, exhibit strong potential to restore oxidative balance, protect cellular integrity, and reduce hypoxia-induced damage. Modulating hypoxia-induced oxidative stress through natural antioxidant pathways offers a promising therapeutic strategy. A deeper understanding of the molecular crosstalk between redox signaling and phytochemical activity may provide new insights for developing preventive and therapeutic interventions against hypoxia-related disorders.
