Mammalian expression vectors are all based on pEGFP-C1 plasmids (Clontech), in which EGFP was replaced by the YFP variant mVenus. The red fluorescent protein monomeric Cherry (mCherry) was used as RFP variant in this paper.
PCR products were ligated into mVenus-C1 plasmids by cutting the vector and PCR product with restriction enzymes BsrGI and KpnI. Restriction sites are marked in bold in primer sequences. In all cases, full length p63RhoGEF16 (link) was used as a template for PCR. To construct YFP-cDH (amino acid 155–347 of p63RhoGEF), p63RhoGEF was amplified using forward primer 5′- GCTGTACAAGTCCAAGAAGGCTCTGGAAAGG-3′ and reverse primer 5′ - ACGGTACCTTAGCCCTCAAATCCCCGCAA-3′. To construct YFP-pmDH (amino acid 1-347 of p63RhoGEF), p63RhoGEF was amplified using forward primer 5′ - GCTGTACAAGTCCCGGGGGGGGCACAAAGGG-3′ and reverse primer 5′-ACGGTACCTTAGCCCTCAAATCCCCGCAA-3′.
RFP variants of these constructs were made by color swapping the mVenus with mCherry with restriction enzymes AgeI and BsrGI.
The RFP-p63RhoGEF and RFP-p63RhoGEF1 (link)2 (link)3 (link)4 (link)5 (link)6 (link)7 (link)8 (link)9 (link)10 11 (link)12 (link)13 (link)14 (link)15 (link)16 (link)17 (link)18 (link)19 (link)20 (link)21 (link)22 (link)23 (link)24 (link)25 (link)26 (link)27 (link)28 (link)29 (link) (amino acid 1–29 of p63RhoGEF) were obtained by cutting the mVenus variants described earlier20 (link) with AgeI and BsrGI and exchanging mVenus for mCherry.
RFP-FKBP12-C1 was obtained as previously described20 (link).
The RFP-FKBP12-cDH was obtained by cutting RFP-FKBP12-C1 with MfeI and Acc651 and inserting the DH domain cut from the RFP-cDH vector with MfeI and BsrGI. A schematic overview of the constructs is depicted in Supplemental Fig. S1.
A Dimerization Optimized Reporter for Activation (DORA) single-chain RhoA biosensor was constructed such that GTP-loading of RhoA is translated into fluorescent protein heterodimerization, thereby increasing FRET.
The DORA-RhoA coding sequence within a pTriEx backbone is MAHHHHHHGSGS-cpPKN-GTGS-cpV-L9H-L9H-L9H-GS-Cer3(1–229)-AS-RhoA. The lay-out is analogous to a previously published RhoA probe21 (link), retaining regulation by Rho GDIs. Introducing the Q63L mutation in RhoA, locking RhoA in the GTP-bound state and mutating PKN1 (L59Q), preventing binding of RhoA, respectively, resulted in constitutive active (RhoAsensor-ca) and non-binding (RhoAsensor-nb) sensors. The detailed development of the sensor will be described elsewhere.
pTriExRhoA1G and pTriExRhoA2G (Addgene plasmid # 40176) were a gift from Olivier Pertz.
EGFP-MKL2 was a kindly provided by J.S. Hinson33 (link). We swapped the EGFP for mVenus with restriction enzymes AgeI and BsrGI.
The Lck-FRB-ECFP (W66A) and Lck-FRB-ECFP were a kind gift from M. Putyrski51 (link), FRB-YFP-Giantin and CFP-FRB-MoA were a kind gift from T. Inoue52 (link). We swapped the YFP in FRB-YFP-Giantin for ECFP (W66A) with restriction enzymes AgeI and BsrGI. We swapped the CFP in CFP-FRB-MoA for ECFP (W66A) with restriction enzymes NheI and BsrGI. A bacterial expression plasmid RSET-YCam 3.6 was a kind gift of A.Miyawaki36 (link). To enable expression in eukaryotic cells we cut the YCam 3.6 coding sequence from the plasmid with NheI and EcoRI and inserted the fragment in a Clontech-style pEGFP-C1 plasmid, cut with the same enzymes.

GTPase activity assays were performed as described (Sander et al. 1998). In brief, lysates of NIH3T3 cells were prepared and incubated with bacterially produced GST-PAK-CD or GST-C21 fusion proteins, bound to glutathione-coupled Sepharose beads. The beads and proteins bound to the fusion protein were washed in an excess of lysis buffer, eluted in Laemmli sample buffer, and analyzed for bound Cdc42, Rac1, or RhoA molecules by Western blot using antibodies against Cdc42 (rabbit polyclonal antibody from Santa Cruz Biotechnology), Rac1 (mAb from Transduction Laboratories or when indicated Upstate Biotechnology Inc.) or RhoA (mAb from Santa Cruz Biotechnology).

The three biosensors were made and used as originally described 4 (link)-6 , with modifications where noted in the text. The Cdc42 biosensor was modified for multiplex imaging by removing EGFP and replacing it with an Alexa750 dye. This produced a biosensor with wavelengths orthogonal to those of the RhoA biosensor. The new Cdc42 biosensor was fused to maltose binding protein to enhance solubility. For control studies a new dual chain RhoA biosensor was constructed by eliminating the linker in the published RhoA biosensor (see Supplementary Material).

Human pulmonary artery endothelial cells (HPAEC) were obtained from Lonza (Allendale, NJ) and cultured in cell growth medium (EGM-2, Lonza) containing 10% fetal bovine serum (FBS). Cell cultures were maintained at 37°C in a humidified 5% CO2 incubator and used for experiments at passages 5-8. In experiments with agonist stimulation, 10% FBS growth medium was replaced with 2% FBS growth medium for 2 hours prior to experiment. Measurements of transendothelial electrical resistance across a confluent endothelial cell monolayer were performed using the electrical cell-substrate impedance sensing system ECIS-1600 (Applied Biophysics, Troy, NY). Transient transfections with cMyc-tagged RhoA-V14 or Rho kinase-CAT (6-553) were performed using PolyJet transfection reagent (SignaGen, Rockville, MD) according to the manufacturer's protocol. In brief, HPAEC were seeded on 35 mm diameter cell culture dishes with biotinylated gelatin-treated coverslips at a density of 5×105 cells per dish. After 24 hours cells were transfected with 1 μg of plasmid DNA per dish (ratio: 1 μg of DNA per 3 μl of PolyJet). Permeability visualization experiments were performed 24 hours after transfection.

mAb B4/7 was derived from a mouse immunized with a protein fraction isolated from detergent extracts of MDCK cells using fusion proteins containing the cytoplasmic domain of low density lipoprotein receptor. Binding of GEF-H1 to this fusion protein was not specific. Hybridoma production and subcloning were as described (Hauri et al., 1985 (link)). Five subclones of the originally isolated hybridoma line were isolated and found to recognize all the same protein in immunoblots and to produce the same pattern in immunofluorescence experiments.
All peptides and antipeptide antibodies were produced by Gramsch Laboratories. The following peptides were used to generate rabbit polyclonal antibodies: anti–cGEF-H1 NH2 terminus, MSRIESLTRARTERC; anti–cGEF-H1 COOH terminus, CDFTRMQDIPEETES; anti–cGEF-H1 alternative domain, CRGHDRLDLSVTIRSVH; anti–ZO-1, YTDQELDETLNDEVC; and anti–claudin-4, PRTDKPYSAKYSAAC. The peptides were conjugated to epoxy-activated Sepharose (Amersham Biosciences), and the antibodies were affinity purified as described (Balda et al., 1996 (link)). For α-tubulin, mAb 1A2 was used (Kreis, 1987 (link)), and in some immunofluorescence experiments ZO-1 was detected with rat monoclonal R40.76 (Anderson et al., 1988 (link)) or with a rabbit polyclonal antibody (Sheth et al., 1997 (link)). α-Catenin was detected with the M12K rabbit polyclonal antibody (Herrenknecht et al., 1991 (link)).

This example demonstrates that statins alleviate LS membrane remodeling phenotypes.

Statins decrease cholesterol (Cho) biosynthesis by inhibiting 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase (FIG. 2A and McFarland et al., Int J Mol Sci 15: 20607-20637 (2014)); consequently, they also down-modulate the downstream synthesis of two intermediates (farnesyl-pyrophosphate and geranyl-geranyl-pyrophosphate) required for RhoA prenylation, which in turn is essential for GTPase membrane anchoring and activation (del Real et al., J Exp Med 200: 541-547 (2004); Demierre et al., Nat Rev Cancer 5: 930-942 (2005); and FIG. 2A). They also have been shown to be active against the RhoA hyperactivation observed in certain cancers (Zhong et al., Cancer Treat Rev 41: 554-567 (2015)).

Several generation statins (Maji et al., Indian J Endocrinol Metab 17: 636-646 (2013)), including fluvastatin, atorvastatin, pitavastatin and rosuvastatin, were tested for their ability to ameliorate LS spreading defects. All statins mitigated to a certain extent the LS spreading phenotype; however, rosuvastatin produced the best results (rosuvastatin>pitavastatin>>>simvastatin and others) in terms of maximizing rescue effect over needed dose and toxicity (FIG. 2B and data not shown).

Phenotype alleviation was observed following the use of an acute rosuvastatin dose (100 μM for 1 h), but similar effect was also evident using lower concentrations (1-10 μM) sustained over longer periods of time (≥72 h; FIG. 2B). Importantly, the latter usage scheme better emulated currently approved treatment conditions with statins that render an effective concentration of free drug in plasma of up to 10 μM (Bjorkhem-Bergman et al., Br J Clin Pharmacol 72: 164-165 (2011)). Following exposure to statins, viability and stress-induced changes in morphology were determined for LS cells (FIG. 2C). Our results showed that rosuvastatin had minimal toxicity, while other statins including pitavastatin and cerivastatin were substantially toxic (FIG. 2C, D). It should be noted that the latter was recalled from the market due to severe rhabdomyolysis effects (Maji et al. (2013), supra). In addition, and to monitor the magnitude of the statins' effects on HMG-CoA reductase in LS cells, we incubated patient fibroblasts in Cho-free media supplemented with vehicle or statins and determined the uptake of fluorescently labeled Cho. While vehicle-treated cells had normal production of endogenous Cho, the ones exposed to statins (due to their HMG-CoA reductase inhibitory activity) were Cho-depleted at a different extent as evidenced by a substantial increase in the uptake of exogenous, fluorescently labeled Cho (FIG. 2E). Our results suggested that rosuvastatin in addition to being less toxic at the chronic dose, led to a less acute inhibition of cholesterol biosynthesis (and consequently to a lower demand of exogenous, fluorescent-analog uptake). However, in contrast with the relatively innocuous chronic exposure (10 μM for ≥72 h), we observed that acute doses of rosuvastatin (100 μM) induced toxicity when exposure time≥15 h (data not shown).
