Abstract:
Lung cancer is a malignant tumor with high morbidity and mortality in the world today. Emerging evidence suggests that PIWI-interacting RNAs (piRNAs) are aberrantly expressed in various human cancers, including lung cancer. Despite of the poorly understood mechanism, piRNAs may work as carcinogenic roles or tumor suppressors by engaging in a variety of cancer-associated signaling pathways. Therefore, they might serve as potential therapeutic targets, diagnostic indicators, or prognostic indicators in lung cancer. This review will discuss the new findings of piRNAs, including their biosynthetic processes, mechanisms of gene suppression, and the significance of these piRNAs tested in lung cancer samples to determine their involvement in cancer progression.

This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
