Pseudogene lncRNAs Regulate Cancer Stem Cell Behavior and Signaling

Research published on August 7, 2025, has highlighted the role of pseudogene-derived long non-coding RNAs (lncRNAs) in regulating the behavior and signaling of cancer stem cells. These molecules are being identified as potential therapeutic targets in cancer medicine due to their ability to modulate the characteristics of these cells.

The findings were detailed in a review titled Emerging roles of pseudogene-derived lncRNAs in cancer stem cells: Non-coding clues and therapeutic targets in cancer medicine, published in the journal Genes Dis. The work was a collaborative effort involving researchers from several institutions, including the Cellular and Molecular Research Center at Shahrekord University of Medical Sciences, the Department of Internal Medicine at Sina Hospital within the Tehran University of Medical Sciences, and the Cellular and Molecular Biology Research Center at Babol University of Medical Sciences.

Mechanisms of lncRNA Regulation

Long non-coding RNAs are molecules that do not code for proteins but instead influence how other genes are expressed. According to reporting from EurekAlert!, these lncRNAs regulate gene expression through four distinct functional pathways.

The research synthesis focuses on pseudogene-derived lncRNAs, exploring their biogenesis and the specific signaling pathways they influence. These molecules are noted for their dual roles in modulating cancer, meaning they can have different effects depending on the cellular context.

Cancer Stem Cells and Homeostasis

The study distinguishes between the behavior of normal stem cells and cancer stem cells. In normal stem cells, biological function and homeostasis are maintained by several highly regulated signaling systems.

When these systems are disrupted or modulated by pseudogene-derived lncRNAs, it can alter the behavior of cancer stem cells. By influencing these signaling pathways, lncRNAs may contribute to the progression and characteristics of the malignancy.

Therapeutic Implications

Because these pseudogene-derived lncRNAs act as non-coding clues in the regulation of cancer stem cells, they are being viewed as viable targets for new medical therapies. The ability to target the specific signaling pathways modulated by these lncRNAs could provide a new avenue for treating cancers that are driven by stem cell behavior.

The research emphasizes that understanding the biogenesis of these molecules is a critical step in developing these therapeutic interventions.
