Silencing and Overexpressing SMAD3 in HCASMCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
SMAD3 (s8401 and s8402) silencer select siRNAs were purchased from Life Technologies. siRNA transfection was performed using Lipofectamine RNAiMAX (Life Technologies). For each well treated with the SMAD3 siRNA or scrambled control (Life technologies, #4390843), the final concentration was 20 nM. HCASMCs were seeded in 6 well plates and grown to 75% confluence before siRNA transfection. HCASMCs were transfected with the SMAD3 siRNA or scrambled control for 12 hours and subsequently collected and processed for RNA isolation after 48 hrs of transfection using the RNeasy kit (Qiagen). For the SMAD3 overexpression study, HCASMCs were transduced with 5ug of pRK5F-SMAD3 cDNA (Addgene plasmid# 12625) or control pCDNA3.1 DNA (ThermoFisher Scientific, plasmid# V79020) using the Amaxa Basic Nucleofector kit for primary mammalian smooth muscle cells (Lonza #VPI-1004) at a density of 1x106 cells per 100 μL sample using Nucleofector Program U-025. Cells were changed to medium with supplements 24hrs after transfection and cultured for an additional 48 hrs. The transduction efficiency was assessed by transducing HCASMCs with 2 μg of pmax-GFP cDNA and quantifying the percentage of GFP positive cells by quantitative fluorescence microscopy.

Human primary Coronary Artery Smooth Muscle Cells (HCASMC, Lonza #CC-2583 Lot 200212 and Cell Applications # 350-05a Lot 1508) were cultured in Smooth Muscle Growth Medium-2 including hEGF, insulin, hFGF-B and FBS, but without antibiotics (Lonza, #CC-3182). For RNA-Seq studies donor-pooled HCASMC were transfected with 300 nM TCF21 Trilencer-27 Human siRNA (OriGene #SR304753C) or Trilencer-27 Universal Scrambled Negative Control siRNA (OriGene #SR30004) at 80% confluence using the Amaxa Basic Nucleofector Kit for Primary Mammalian Smooth Muscle Cells (Lonza #VPI-1004) at a density of 1 × 106 cells per 100 μL sample using Nucleofector Program U-025. Cells were changed to medium with supplements at 18 hours post-transfection and cultured for an additional 48 hours.

HOXA13 Overexpression in Smooth Muscle Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
HOXA13 overexpression plasmid, pLV(Exp)-EGFP:T2A:Puro-CBh > hHOXA13, vector ID VB180306-1076naw, was constructed and packaged by VectorBuilder (Cyagen Bioscience). Nucleofection was carried out using Amaxa Basic Nucleofector Kit for Primary Mammalian smooth muscle cells (Lonza, Catalog # VPI-1004) according to manufactures protocol. Briefly, 1X106 cells was resuspended in 100μl Nucleofector solution, and transfected with 1μg of HOXA13 overexpression plasmid using program P-024. Following nucleofection, cells were incubated for 18 hours and media was changed to complete growth media along with supplements. 48 hours after nucleofection, the cells were treated with 2μg/ml puromycin to select for stable expression. Expression analysis was determined by qRT-PCR on cloned cells (n=4) with RPL17 as the housekeeping gene.

MSC Stable Transfection with mCherry

PiggyBac transposon‐based strategy was used for MSCs stable transfection with mCherry (Yusa, Zhou, Li, Bradley, & Craig, 2011). The coding region of mCherry was amplified by PCR and cloned into the XbaI/EcoRI sites of the backbone PiggyBac vector PB‐CMV‐MCS‐EF1‐Puro (System Biosciences; Cat. No. PB5105B‐1). For further genomic integration, the following vector was used: pCMV‐hyPBase (provided by the Wellcome Trust Sanger Institute). MSCs obtained from 2 and 20 months old male rats were transfected with PB‐CMV‐mCherry‐EF1‐Puro and pCMV‐hyPBase plasmids. Amaxa® Basic Nucleofector® Kit for Primary Mammalian Smooth Muscle Cells (Lonza) and the program U‐023 were used to transfect 5 × 106 cells with 4 μg of PB‐CMV‐mCherry‐EF1‐Puro and 1 μg of pCMV‐hyPBase. This methodology allowed approximately 40% of transfection efficiency. For further selection, transfected cells were incubated in the presence of 2 μg/mL puromycin (Sigma) for at least 1 week, leading to a highly pure mCherry‐expressing MSCs culture.

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.
