Article Snippet: The control strain mRuby2+ containing the mRuby2 reporter directly fused to the C-termini of RPL13A encoding a ribosomal protein was constructed using the CRISPR/Cas9 technology, transforming a cut EC2_5 vector (Cámara, Lenitz and Nygård ) with an sgRNA targeting the RPL13A locus (GAAGGAAAATACAAAAATTG) and a dDNA containing the mRuby2 ORF amplified from pYTK034 (Addgene #65141) using primers with 40-bp sequences for in vivo homologous recombination.

Figure Lengend Snippet: Schematic presentation of the biosensor and control constructs. For strain details, see Table . Haa1 with fusion proteins is expected to relocate to the nucleus upon acetic acid exposure. The biosensor output is the expression of the reporter ( mRuby2 or mCherry ), expressed under various synthetic promoters. Sizes of promoters and genes are scaled to represent their actual sizes and added BSs for the sTFs are indicated with black bars inside the promoters. Red arrows labeled with R and C refer to the mRuby2 or mCherry reporter genes. Cyan arrows labeled with T and BHT refer to mTurquoise2 or BM3R1-HAA1-mTurquoise2 .

Figure Lengend Snippet: CLASP2 and G2L1 colocalize in 3T3-L1 adipocytes. A–B, Live-cell imaging of adipocytes cultured in complete media coexpressing mRuby2-Tubulin (magenta) and GFP-CLASP2-HA (A, green) or mCherry-G2L1-myc (B, green). Live cells were imaged using TIRFM on a 2-s acquisition interval. Time series images to the right of the whole cell image are used to highlight +TIP dynamics within the indicated ROI. C, Immunofluorescence images of adipocytes cultured in complete media cooverexpressing GFP-CLASP2-HA (green) and mCherry-G2L1-myc (magenta). Cells were fixed and immunolabeled for tubulin (inverted white). Bottom row is magnified ROI. ROI, region of interest. Scale bar = 20 μm.

Article Snippet: To generate pLenti-iRFP670-Tubulin, tubulin was first subcloned out of the mRuby2-Tubulin-6 vector and into piRFP670-N1 (Addgene #45457, a gift from Vladislav Verkhusha). iRFP670-Tubulin was then subcloned out of the piRFP670-Tubulin vector and into the pLenti backbone to generate pLenti-iRFP670-Tubulin.

Figure Lengend Snippet: The effect of insulin on CLASP2 +TIP dynamics. Live-cell imaging of adipocytes serum-starved for one hour and subsequently stimulated with 100 nm insulin. Live cells were imaged using TIRFM on a two-second acquisition interval. A, Single frame of live-cell imaging of adipocytes coexpressing GFP-CLASP2 (green) and mRuby2-Tubulin (magenta) at basal state (top row) or 10 mins (bottom row) following insulin stimulation. CLASP2 is displayed in inverted white to highlight +TIP density. B, Quantification of CLASP2-containing +TIP density per unit area (μm2) in adipocytes at basal state or 10 mins following insulin stimulation. Percent increase in CLASP2-containing +TIP density is indicated to the right. Statistical comparison made by paired parametric t test, n = 5 cells. C, Temporally color-coded projection of GFP-CLASP2 localization during a 30 s live-cell imaging interval. The length and extent of color overlap of time-projected CLASP2 localization indicates reduced displacement and hence lower velocity of CLASP2-containing +TIPs during the imaging interval in adipocytes after 10 mins of insulin stimulation. D, Quantification of CLASP2-containing +TIP velocity in adipocytes at basal state or 10 mins following insulin stimulation indicates reduced velocity of CLASP2-containing +TIPS after insulin treatment. Statistical comparison made by unpaired parametric t test, n = 123–125 CLASP2-containing +TIPS from five cells. Scale bars = 5 μm. E, Image of entire cells in the basal state (left panel) or 8 mins post insulin treatment (right panel) extracted from supplemental Video 2. Time series images under the whole cell image are used to highlight insulin-stimulated +TIP dynamics within the indicated ROI. F, Time series extracted from supplemental Video 2 of the indicated ROIs at either the basal state or at 4 mins post insulin treatment to present an example of changing CLASP2 microtubule plus-end dynamics with insulin stimulation. G, Live cell CLASP2-containing +TIP dynamics of the ROI extracted from supplemental Video 2 were captured in the basal state followed by stimulation with insulin. Each insulin-stimulated CLASP2-containing +TIP trail length time point was compared against the basal CLASP2-containing +TIP trail length to test for significant differences. t test; *p ≤ 0.05, **p ≤ 0.01. Red circles represent outlier data points. ROI, region of interest. BAS, basal. INS, insulin. Scale bar = 10 μm.
