| Title |
Fus/Tls anti-sense oligo rep1 |
| Sample type |
RNA |
| |
|
| Source name |
Striatum
|
| Organism |
Mus musculus |
| Characteristics |
tissue: brain striatum
genetic background: C57BL/6
age: 8-10 weeks
treatment: Fus/Tls anti-sense oligo
|
| Treatment protocol |
8-10 week old female C57Bl/6 mice were anesthetized with 2.5-3% isofluorane, and a midline incision of approximately 1cm was made on their heads. Using stereotaxic guides, 3 mL of antisense oligonucleotide (ASO) solution targeting Tdp-43 or a control – corresponding to a total of 75 mg or 100 mg ASOs – or saline buffer was injected using a Hamilton syringe directly into their striatum. The incision was closed with sutures and the mice were allowed to recover in their cages. They were monitored for any adverse effects for the next two weeks until they were sacrificed. The striatum and adjacent cortex area were dissected, placed in separate tubes containing 1 mL Trizol (Invitrogen) and were frozen at -80oC until use.

| Extracted molecule |
total RNA |
| Extraction protocol |
Trizol extraction of RNA and protein was performed according to the manufacturer’s instructions. In summary, tissues were homogenized in Trizol using a Polytron homogenizer (Company) for 15 sec. Homogenates were then incubated at room temperature for 5min. Chloroform was added to the homogenates (200 l per 1 mL of Trizol) and tubes were shaken vigorously for 15 sec. After incubation at room temperature for 2-10 min, samples were centrifuged at 12,000 g for 15 min at 4oC. The RNA-containing aqueous phase was transferred to fresh tubes and after the addition of glycogen and isopropanol, RNA was precipitated at -20oC overnight. The next day, samples were centrifuged for 10 mins at maximum speed in a microcentrifuge at 4oC. RNA pellets were washed with 75% Ethanol twice, dried at room temperature and reconstituted in DEPC-treated water.

| Hybridization protocol |
Hybridization cocktails containing ~5.5 ug of fragmented and labeled DNA target were prepared and applied to GeneChip Human Splice Junction arrays. Hybridization was performed for 16 hours using the Fluidics 450 station.
|
| Scan protocol |
Arrays were scanned using the Affymetrix 3000 7G scanner and GeneChip Operating Software version 1.4 to produce .CEL intensity files.
