ABSTRACT
Cancer remains a serious healthcare problem despite significant improvements in early detection and treatment approaches in the past few decades. Novel biomarkers for diagnosis and therapeutic strategies are urgently needed. In recent years, long noncoding RNAs (lncRNAs) have been reported to be aberrantly expressed in tumors and show crosstalk with key cancer-related signaling pathways. In this review, we summarized the current progress of research on cytoplasmic lncRNAs and their roles in regulating cancer signaling and tumor progression, further characterization of which may lead to effective approaches for cancer prevention and therapy.

Exosomes and long non-coding RNAs (lncRNAs) are emerging as important elements contributing to a more comprehensive understanding of cancer development and progression. The discovery of lncRNAs in exosomes further indicates their bona fide biological functional roles in cancer development and drug resistance. In this review, we describe the biogenesis of exosomes and summarize the function of exosomal lncRNAs in the field of cancer research. These findings strikingly advance current knowledge of exosomal lncRNAs and suggest that they may be promising diagnostic biomarkers and therapeutic targets for cancer.
