Tumor-derived exosomal miR-103a-3p promotes vascular permeability and proliferation by targeting ZO-1 and ACOX-1 in nasopharyngeal carcinoma.

ABSTRACT:

Background

miR-103a-3p has been reported to be a factor leading to poor prognosis in several human malignancies, including nasopharyngeal carcinoma (NPC). Secreted microRNAs containing exosomes may mediate the communication between cancer and stromal cells. The purpose of the current work was to learn more about miR-103a-3p's function in NPC exosomes.

Methods

Transmission electron microscopy and NanoSight analysis were used to verify the existence of exosomes. To determine the relationship between exosomal miR-103a-3p and carcinogenesis in NPC, gain- and loss-of-function studies were carried out.
