Figure 4. COPII-mediated ER to Golgi transport is required for activation of LX-2 cells upon TGF- β1 stimulation. (a) LX-2 cells transfected with the indicated siRNA(s) were cultured for 24 h in DMEM supplemented with 10% FBS. After starvation for 24 h with DMEM supplemented with 0.5% FBS, the cells were untreated or treated with 1 ng/ml TGF-β1 and cultured for 3 days. Proteins were extracted and subjected to SDS-PAGE, followed by western blotting with anti-collagen I, anti-Sec23A, anti-Sec24D, anti-α-SMA and anti-GAPDH antibodies (lysates). Medium was collected for SDS-PAGE followed by western blotting with anti-collagen I antibody (medium). Shown is a representative immunoblot analysis (n = 3).

Sar1 membrane association is efficiently detected using the Split mNeonGreen system. (A) Schematic representation of the SAIYAN system. The membrane-spanning regions of TANGO1S and HA-tag fused to 10 of the 11 strands of mNG (mNG 1–10 ) were expressed in cells. In addition, <t>Sar1A</t> constructs with a FLAG-tag and a glycine linker fused to the 11th strand of mNG (mNG 11 ) were also expressed. Upon Sar1A activation, mNG 1–10 and mNG 11 combined to form the complete mNG proteins, inducing mNG signals. (B) HA-mNG 1–10 cells transfected with the indicated Sar1A constructs were fixed and stained with anti-Sec16-C and anti-FLAG antibodies. Scale bar = 10 µm. (C) Quantification of mNG intensity from B (arbitrary units [A.U.]). Error bars represent the means ± SEM. Each data point represents the mNG intensity of the analyzed cells.

The expression of the <t>SAR1A</t> and SAR1B genes in intestinal biopsies of healthy individuals and an Anderson's disease patient . The graph shows the log base 2 fold change (increase or decrease), as measured by RTQPCR, in the expression of the SAR1A and SAR1B genes in 4 healthy normal adults (NA1, NA2 NA3 and NA4), one healthy young adult (YA1) and two healthy children (C1 and C2) normalized to an Anderson's disease patient (AD3). Gene expression was measured in biopsies obtained on two separate occasions from the young adult (YA1) and from one of the children (C1). The standard deviation of the measurements are shown and, except for the value for SAR1A for NA1, all the differences are significant (p < 0.01) as compared to the patient.

Production of Sar1A/SAIYAN cells. (A) Doxycycline-inducible stable cell lines expressing the membrane-spanning regions of TANGO1S and HA-tag fused to 10 of the 11 strands of mNG were established using a lentiviral system and G418 selection (HA-mNG 1–10 cells). Stable cells were subsequently electroporated with Cas9 protein, sgRNA, and ssDNA to facilitate the knock-in of FLAG-mNG 11 into the Sar1A locus of the genome. Cells were treated with doxycycline for 24 h and further sorted via FACS to isolate single cells exhibiting mNG signals into 96-well plates. The expanded cell population was then collected and subjected to genomic sequencing. Positive clones were identified and selected for further analysis (Sar1A/SAIYAN cells).

Figure Lengend Snippet: Production of Sar1A/SAIYAN cells. (A) Doxycycline-inducible stable cell lines expressing the membrane-spanning regions of TANGO1S and HA-tag fused to 10 of the 11 strands of mNG were established using a lentiviral system and G418 selection (HA-mNG 1–10 cells). Stable cells were subsequently electroporated with Cas9 protein, sgRNA, and ssDNA to facilitate the knock-in of FLAG-mNG 11 into the Sar1A locus of the genome. Cells were treated with doxycycline for 24 h and further sorted via FACS to isolate single cells exhibiting mNG signals into 96-well plates. The expanded cell population was then collected and subjected to genomic sequencing. Positive clones were identified and selected for further analysis (Sar1A/SAIYAN cells).
