Sample GSM1909396 Query DataSets for GSM1909396
Status Public on Oct 15, 2017
Title C02 Pre
Sample type RNA
Source name C02 Pre Serum
Organism Homo sapiens
Characteristics biological fluid: Serum
bmi pre: 48
bmi post: 31.8
age: 41
race: AF
Sex: Female
Treatment protocol No Treatment
Growth protocol Human bariatric patient pre and post surgery serum (500 uL) was used for isolation of FABP4+ exosomes.
Extracted molecule total RNA
Extraction protocol To isolate exosomes, we used the serum from the bariatric patients (pre and post surgery) and used ExoQuick-TC precipitation solution, according to ExoQuick-TC protocol. Total RNA was isolated following mirVana's total RNA Isolation kit. We also used StemCell Technologies Magnetic Isolation Technique to isolate FABP4+ specific exosomes.
Label biotin
Label protocol We used Affymetrix FlashTag Biotin HSR RNA Labeling Kit to label 1000 ng of cRNA from each sample.
Hybridization protocol For hybridization, we followed Affymetrix Gene Chip miRNA Array Procedure for Affymetrix miRNA 4.0 arrays to hybridize biotin-labeled sample.
Scan protocol We scanned the Affymetrix miRNA 4.0 arrays following the Affymetrix Command Console User Manual Instructions.
Description FABP4+ exosomes (adipocyte-derived) were isolated, amplified, and profiled from serum taken post bariatric surgery.
Data processing We analyzed the resulting data in Expression Console using RMA+DMBG (Affymetrix) and then exported it to Partek Genomics Suite for analyses. We used three-factor ANCOVA (ID*group (lean vs. obese)*adipose depot; age covariate) to compare miRNA expression, using unadjusted p ≤ 0.05 and fold change ≥ |1.2| as filters. We generated main effects for group (obesity-state) and tissue depot along with their interaction term. As a part of the overall ANCOVA, we used specific within-group (depot effects within obese or lean) and within-tissue (obesity effects within depot) contrasts. No corrections were made for multiple testing, as the primary purpose of list generation was to power pathway analysis, which mitigates false positive discovery risks.
