ln Vitro |
The miR-17 seed sequence is completely complementary to RGLS4326, a single-stranded, chemically altered 9-nt short oligonucleotide. In ADPKD, RGLS4326 suppresses the miR-17 family's pathogenic activity [1]. According to miR-17 PD-Sig, RGLS4326 administration reduces miR-17 function in renal collecting duct cells in culture, with an EC50 value of 77.2 ± 20.2 nM [1]. Human autosomal dominant polycystic kidney disease (ADPKD) cysts are inhibited from growing by RGLS4326 [1].
|
ln Vivo |
RGLS4326 distributes to renal tubules and cysts more selectively. With a half-life of less than four hours in wild-type mice and a Tmax of less than one hour and a Cmax of 8.5 μg/mL, RGLS4326 (single 30 mg/kg subcutaneous injection) is quickly absorbed into plasma [1]. The direct miR-17 target genes Pkd1 and Pkd2 are likewise upregulated in expression when RGLS4326 is administered in vivo[1].

Cell Assay |
Cell Proliferation Assay[1]
Cell Types: Primary cysts in 3D Matrigel Tested Concentrations: 5, 20, 100, and 300 nM Incubation Duration: 9 days Experimental Results: diminished in cyst epithelial cell proliferation. |
Animal Protocol |
Animal/Disease Models: Pkd2-KO mice[1]
Doses: 20 mg/kg Route of Administration: SC injection Experimental Results: Compared to non-cystic control kidneys, polycystic kidneys of PBS-treated Pkd2-KO mice exhibit an age-dependent progressive decline in miR-17 PD-Sig, indicative of increasing miR-17 activity with disease progression. Administration of RGLS4326 reversed this decline in miR-17 PD-Sig, indicating a sustained functional inhibition of miR-17. |

Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
