Table 1

Summary of the current studies that evaluated microRNAs expression profiles in adrenocortical tumors.

Study TumorsDysregulated microRNAsMajor findings

Tömböl et al., 2009 [47]8 ACAs/4 ACCs/4 normal corticesmiR-184, miR-210, miR-503
miR-214, miR-511
Difference between dCTmiR-511 and dCTmiR-511 was able to differentiate adenomas from carcinomas

Soon et al., 2009 [48]27 ACAs/22 ACCs/6 normal corticesmiR-195, miR-335, miR-7High levels of miR-483-5p and low levels of miR-195 predicted worst overall survival

Patterson et al., 2011 [50]26 ACAs/10 ACCs/21 normal corticesmiR-483-5p
miR-195, miR-125b, miR-100
Overexpression of miR-483-5p was able to diagnose carcinomas. The miR-483-5p and IGF2 were coexpressed

Özata et al., 2011 [52]26 ACAs/22 ACCs/10 normal corticesmiR-483-3p, miR-483-5p, miR-210, miR-21
miR-1974, miR-195, miR-497
Downregulation of miR-483-3p and overexpression of miR-195 or miR-497 led to induction cell death in vitro

Chabre et al., 2013 [53]16 ACAs/30 ACCsmiR-483-5p
miR-195, miR-335
High circulation levels of miR-483-5p or low levels of miR-195 were associated with worst recurrence-free and overall survival

ACAs: adrenocortical adenomas; ACCs: adrenocortical carcinomas; miRNAs in bold are overexpressed and regular ones are underexpressed in carcinomas comparing to adenomas.
