description | Background
Infection by Adenovirus 36 (Ad-36) has been associated with adipogenesis using cell and animal models, and a high risk of developing obesity has been reported in Ad-36-seropositive individuals. However, molecular mechanisms involved in the maintenance over the years of adipogenesis associated with Ad-36 has not been investigated in human adipose tissue. Epigenetic mechanisms, such as micro-RNAs (miRNAs) that regulate gene expression at the post-transcriptional level, have shown an important role in the development and maintenance of metabolic diseases.
Aim
This study investigated the expression of miRNA associated with the adipogenic process in visceral adipose tissue from obese individuals according to Ad-36 serology.
Methods
Obese individuals were separated according to their status of Ad-36 serology in seropositive (Ad-36 (+);
n
= 29) and seronegative (Ad-36 (−);
n
= 28) groups. Additionally, a group of lean controls (
n
= 17) was selected to compare with obese individuals. Biopsies of visceral adipose tissue were obtained to evaluate miRNA and gene expression. The study of Ad-36 serology was carried out by ELISA. The expression of pro-adipogenic (miR-17 and miR-210) and anti-adipogenic (miR-155, miR-130 and miR-27a) miRNAs was evaluated using Taqman advanced miRNA assays by qPCR. The expression of adipogenes encoding
LEP

ADIPOQ
, and
PPARγ
was evaluated by Taqman predesigned assays through qPCR.
Results
The obese group had higher

PPARγ

Conclusions
Individuals with previous infection by Ad-36 had higher expression of the pro-adipogenic miR-17 and lower expression of the anti-adipogenic miR-155, which could lead to an increased adipogenic status by positively modulating

Infection by Adenovirus 36 (Ad-36) has been associated with adipogenesis using cell and animal models, and a high risk of developing obesity has been reported in Ad-36-seropositive individuals. However, molecular mechanisms involved in the maintenance over the years of adipogenesis associated with Ad-36 has not been investigated in human adipose tissue. Epigenetic mechanisms, such as micro-RNAs (miRNAs) that regulate gene expression at the post-transcriptional level, have shown an important role in the development and maintenance of metabolic diseases.
Aim
This study investigated the expression of miRNA associated with the adipogenic process in visceral adipose tissue from obese individuals according to Ad-36 serology.
Methods
Obese individuals were separated according to their status of Ad-36 serology in seropositive (Ad-36 (+);
n
= 29) and seronegative (Ad-36 (−);
n
= 28) groups. Additionally, a group of lean controls (
n
= 17) was selected to compare with obese individuals. Biopsies of visceral adipose tissue were obtained to evaluate miRNA and gene expression. The study of Ad-36 serology was carried out by ELISA. The expression of pro-adipogenic (miR-17 and miR-210) and anti-adipogenic (miR-155, miR-130 and miR-27a) miRNAs was evaluated using Taqman advanced miRNA assays by qPCR. The expression of adipogenes encoding
LEP
,
ADIPOQ
, and
PPARγ
was evaluated by Taqman predesigned assays through qPCR.
Results
The obese group had higher
LEP
(
p
< 0.001) and
PPARγ
(
p
= 0.016) expression and lower
ADIPOQ
expression (
p
= 0.017), and also had higher expression of miR-210 (
p
= 0.039), whereas lower expression of miR-155 (
p
= 0.019) and miR-27a (
p
= 0.028) as compared to lean controls. Higher
PPARγ
expression (
p
= 0.008), but no influence on

expression was observed in Ad-36 (+) group. Those seropositive individuals also had higher expression of the miR-17 (
p
= 0.028) and lower levels of miR-155 (
