Targeting microRNAs with thymoquinone: a new approach for cancer therapy

Area of Science:

• Oncology
• Molecular Biology
• Natural Product Chemistry

Background:

• Cancer remains a leading global cause of mortality despite advances in conventional treatments.
• Bioactive natural compounds are increasingly recognized for their therapeutic potential in chronic diseases, including cancer.
• Thymoquinone (TQ), derived from black cumin seeds, exhibits significant anti-cancer properties in preclinical models.

Purpose of the Study:

• To review the molecular mechanisms underlying the anti-cancer effects of Thymoquinone (TQ).
• To explore TQ's role in modulating microRNA (miRNA) expression for cancer therapy.
• To highlight miRNAs as potential biomarkers for cancer diagnosis, prognosis, and treatment.

Main Methods:

• Literature review of studies investigating Thymoquinone (TQ) and its effects on cancer.
• Analysis of research on miRNA regulation by TQ in various cancer models.
• Synthesis of findings on the molecular pathways targeted by TQ-modulated miRNAs.

Main Results:

• Thymoquinone (TQ) demonstrates broad-spectrum anti-cancer activity across diverse animal models.
• TQ effectively modulates the expression of specific microRNAs (miRNAs) implicated in cancer development and progression.
• These miRNA modulations influence key cellular processes, including gene expression and signaling pathways relevant to tumorigenesis.

Conclusions:

• Thymoquinone (TQ) represents a promising natural compound for cancer therapy, primarily through its ability to regulate miRNA expression.
• Targeting miRNAs offers a novel strategy for developing more effective and potentially less toxic cancer treatments.
• Further research into TQ-mediated miRNA modulation could lead to improved diagnostic and therapeutic approaches for cancer patients.
