Title |
Gene expression profiling of FSHMD1A muscle (9a) |
Sample type |
RNA |
|
|
Channel 1 |
Source name |
FSHMD1A deltoid muscle n°9(a)
|
Organism |
Homo sapiens |
Characteristics |
- Sex: M - Age (years): 13 - EcoR1 Fragment length (Kb): 10 - Clinical severity: high - Inflammation signs: minimal - Regenerating fibres: none - Ragged-red-fibres: none - Myopatic features: minimal
|
Biomaterial provider |
Muscle specimens were obtained from FSHMD1A patients examined at the Institute of Neurology of the Catholic University of Rome or at the Center for Neuromuscular diseases (U.I.L.D.M. Sezione Laziale), Rome.
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was isolated using the TRIZOL reagent (Invitrogen/Life Technologies) and purified using RNeasy Mini Kit (Qiagen, Hilden, Germany).
|
Label |
cy5
|
Label protocol |
Linear amplification of mRNA was carried on using the Message-Amp-aRNA kit (Ambion, TX, USA) with two consecutive amplification steps, according to the manufacturer’s recommendations. Fluorescent cDNA targets were prepared by direct labelling 1.5 ug of aRNA from each sample.
|
|
|
Channel 2 |
Source name |
normal deltoid control
|
Organism |
Homo sapiens |
Characteristics |
Pool of ten human deltoideous normal muscles
|
Biomaterial provider |
Muscle specimens were obtained from subjects in whom a muscle disease was excluded by both clinical and histopathological criteria.
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was isolated using the TRIZOL reagent (Invitrogen/Life Technologies) and purified using RNeasy Mini Kit (Qiagen, Hilden, Germany).
|
Label |
cy3
|
Label protocol |
Linear amplification of mRNA was carried on using the Message-Amp-aRNA kit (Ambion, TX, USA) with two consecutive amplification steps, according to the manufacturer’s recommendations. Fluorescent cDNA targets were prepared by direct labelling 1.5 ug of aRNA from each sample.

Hybridization protocol |
Microarray hybridization was carried out in a dual slide chamber (HybChamber, Gene Machines, San Carlos, CA, USA) humidified with 100 ul of 3 x SSC. Labeled cDNA was dissolved in 40 ul of hybridization buffer, denatured at 90°C for 2 min and applied directly to the slides. Hybridization was performed overnight at 42°C by immersion in a water bath (W28, Grant, Cambridge, UK). The following post-hybridization washes were performed: 1XSSC, 0.1% SDS for 4 min at 42°C, 0,1X SSC, 0.1% SDS for 4 min at room temperature and 0,2X SSC for 2 min at room temperature.
|
Scan protocol |
Digital images were generated in a GSI Lumonics LITE dual confocal laser scanner (ScanArray Microarray Analysis Software) and processed with QuantArray Analysis Software (GSI Lumonics, Ottawa, Canada).
|
Description |
We compared the transcription profiles of FSHMD1A deltoideous muscles with a pool of 10 human deltoideous muscles obtained from normal donors, in a microarray competitive hybridization.
|
Data processing |
Normalized data were determined using the publicly available software MIDAS (TIGR Microarray Data Analysis System: http://www.tigr.org/softlab/). Normalized values (lowess normalization) were calculated for each spot, and converted in logarithmic scale. Final values correspond to log(2) ratio of the normalized intensities.
