RGS5 Silencing in HUASMCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
For functional studies of RGS5, an siRNA-based silencing approach was used. Control siRNA (siGENOME Non-Targeting siRNA Pool #2, Thermo Scientific, Germany) and customized RGS5-targeting siRNA (sense: CCUGAAGUCUGAAUUCAGU, antisense: CCAUGAAUGUGGACUGGCA) was purchased from Sigma-Aldrich and used at a concentration of 100 nM. HUASMCs were transfected by utilizing the MATRAsi technique (IBA bioTAGnology, Göttingen, Germany) according to the manufacturer's instructions. Transfected cells were incubated for 48 h, and the siRNA-based knockdown efficiency was verified before further usage (Supplementary Fig S4).

Check if the same lab product or an alternative is used in the 5 most similar protocols
A mammalian expression plasmid of N-terminal myc-FLAG-tagged human SPHK1 (GenBank data base accession number NM_021972) and one encoding Sp1 under the control of cytomegalovirus promoter were purchased from OriGene (Rockville, MD). Three kinds of siRNAs targeting Sp1 (FlexiTube GeneSolution GS6667 SI#00150983, 02648065, and 02648072) were purchased from Qiagen (Hilden, Germany), as well as non-targeting siRNA (siGENOME Non-Targeting siRNA Pool #2, #D-001206-14-50) from Thermo Fisher Scientific (Waltham, MA). Peretinoin was kindly provided by Kowa Company (Aichi, Japan). Sphingosine kinase inhibitor 2 (SKI II, formally 4-[[4-(4-chlorophenyl)-2-thiazolyl]amino]-phenol) was purchased from Cayman Chemical Company (CAS No 312636-16-1; Ann Arbor, MI). These compounds were dissolved in DMSO. All final dilutions contained 0.5% DMSO. DEN was purchased from Sigma-Aldrich (St. Louis, MO).

siRNA Screening for Deubiquitinating Enzymes

Check if the same lab product or an alternative is used in the 5 most similar protocols
UACC257, M14, A2058, Malme-3M, SK-MEL-28, and MeWo cell lines were purchased from ATCC, and cultured in RPMI1640 supplemented with 2 mM l-glutamine, 10% fetal bovine serum, 100 units/mL of penicillin, and 100 μg/mL of streptomycin. The cells were maintained at 37 °C in a humidified atmosphere of 5% CO2.
For small interfering RNA (siRNA) screening, 12.5 nM Dharmacon siGENOME SMARTpool siRNA Library (Human Deubiquitinating Enzymes) and siGENOME Non-targeting siRNA Pool #2 (Thermo Fisher Scientific, Rockford, IL, USA) were reverse-transfected to UACC257 and M14 cells using Lipofectamine RNAiMAX reagent (Thermo Fisher Scientific). Other siRNAs were purchased from Thermo Fisher Scientific. For siRNA knockdown experiments, siRNA for PSMD14 (siPSMD14) (s19919 and s19920), siRNA for UBL5 (siUBL5) (s224521, s224522), siRNA for BAP1 (siBAP1) (s15821, s15822), siRNA for SMAD2 (s8397), siRNA for SMAD3 (s8402), or negative control #1 (siCNTL) was transfected at a final concentration of 12.5 nM into UACC257 or M14 cells using Lipofectamine RNAiMAX reagent. Transfected cells were subjected to CellTiter-Glo luminescent cell viability assay, Western blotting, and qRT-PCR after 96 h.

Lentiviral and Retroviral Transduction for Stable Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
Non-targeting control siRNA (siGENOME Non-Targeting siRNA Pool #2) and PARK2-targeting siRNAs were purchased from Thermo Scientific, and were transfected using RNAi MAX (Invitrogen). The sequences of all siRNAs and shRNAs are listed in Supplementary Table 2. For lentiviral particle production, HEK293T cells were co-transfected using jetPRIME (Polyplus-transfection) with shRNA constructs, SHC003-based overexpression constructs and MISSION packaging plasmid mix (Sigma). For retroviral particle production, pMSCV-PIG- or pBABE-Puro-based vectors were co-transfected together with Env and Gagpol plasmids into HEK293T. The culture medium was replaced with fresh medium after 6 h, and supernatants were harvested at 48 h and 72 h post transfection. For generation of stable lines, the cells were infected with viral particles in the presence of 8 μg/mL polybrene followed by puromycin selection.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
