Research overview

Bladder cancer (BCa) is a prevalent genitourinary malignancy characterized by limited specific diagnostic and therapeutic options. Although hypoxia is known to drive tumor progression via exosome-mediated communication, the specific oncogenic roles of hypoxia-induced exosomal long non-coding RNAs (lncRNAs) remain poorly elucidated.

Key findings

Bladder cancer (BCa) is a prevalent genitourinary malignancy characterized by limited specific diagnostic and therapeutic options.

Although hypoxia is known to drive tumor progression via exosome-mediated communication, the specific oncogenic roles of hypoxia-induced exosomal long non-coding RNAs (lncRNAs) remain poorly elucidated.

Here, we profiled exosomes from normoxic and hypoxic BCa cells using high-throughput sequencing, identifying LNCOC1 as a significantly upregulated lncRNA under hypoxic conditions.

Mechanistically, hypoxia-inducible factor 1α (HIF1A) directly binds to the LNCOC1 promoter to drive its transcription and subsequent exosomal encapsulation.
