ABSTRACT

Objective:

To comprehensively analyze the expression profile of circular RNA (circRNA) and construct competing endogenous RNA (ceRNA) regulatory networks in tuberous sclerosis complex related renal angiomyolipoma (TSC-RAML).

Methods:

According to the diagnostic criteria of TSC determined by the international consensus group on tuberous sclerosis in 2012, tumor tissues and paired normal renal tissues of 3 patients with TSC-RAML who were diagnosed in our hospital from January 2017 to January 2019 were collected. The circRNA, miRNA and mRNA of 3 paired samples were detected by circRNA, miRNA chip technology and next generation sequencing respectively, and the differential molecules were determined. Gene Ontology(GO) functional enrichment analysis and Kyoto Encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed based on differential mRNA molecules and host genes of circRNA. Based on differential circRNA, miRNA and mRNA, up-regulated and down-regulated ceRNA regulatory networks were established.

Results:

A total of 330 up-regulated and 336 down-regulated differential circRNA, 8 up-regulated and 7 down-regulated miRNA, 800 up-regulated and 1130 down-regulated mRNA were screened. Through GO and KEGG enrichment analysis, many pathways including lipid metabolism, focal adhesion and mineral absorption were abnormally altered. Finally, the up-regualted ceRNA network led by hsa_circ_0092022, hsa_circ_0076859 and hsa_circ_0033388 and down-regulated network led by hsa_circ_0000374, hsa_circ_0000141, hsa_circ_0072665, hsa_circ_0009503 and hsa_circ_0000009 were constructed.

Conclusions:

There were many differentially expressed circRNA between TSC-RAML and paired normal renal tissues. ceRNA regulatory networks may be involved in the occurrence and development of TSC-RAML.
