Article Title: Targeting AKAP13 RhoGEF activity ameliorates pro-fibrotic phenotypes driven by the IPF associated AKAP13 risk variant

doi: 10.64898/2026.01.21.700846

Figure Lengend Snippet: (A) RhoA activity measured by RhoA G-LISA in wild-type (blue) and rs62025270 (red) iHBECs treated with or without 50 µM LPA for 2 minutes. Data are presented as raw OD values at 490 nm (n = 3). (B) Real-time cell impedance analysis of wild-type (blue) and rs62025270 (red) iHBECs using the xCELLigence RTCA system. Data are shown as cell index over a 5-hour period (n = 3). (C) Representative immunoblot images of phospho-SMAD2 and total SMAD2/3 in iHBECs treated with or without 50 µM LPA for 2 hours. (D) Densitometric quantification of immunoblots shown in (C), presented as phospho-SMAD2 relative to total SMAD2/3 (n = 3). Statistical analysis was performed using a paired t-test between wild type and rs62025270 treated with LPA. * p<0.05, ** p<0.01.

Figure Lengend Snippet: (A) Schematic representation of cDNA constructs encoding full-length AKAP13, Proto-Lbc, and △-Lbc. (B) RhoA activity measured by RhoA G-LISA in iHBECs transfected with empty vector, Proto-Lbc, or △-Lbc., followed by treatment with or without 50 µM LPA for 2 min. Data are presented as fold change relative to control (n = 3). (C) Representative immunoblot showing expression of FLAG-tagged Proto-Lbc and Δ-Lbc in iHBECs. (D) Real-time cell impedance measurement of iHBECs using the xCELLigence RTCA system. Data are shown as normalised cell index over a 5-hour period (n = 3).

Figure Lengend Snippet: (A) Real-time cell impedance analysis of wild-type (blue) and rs62025270 (red) iHBECs treated with 3 µM A13 or DMSO control using the xCELLigence RTCA system. Data are presented as cell index over a 5-hour period (n = 3). (B) RhoA activity measured by RhoA G-LISA in WT (blue) and rs62025270 (red) iHBECs treated with or without 50 µM LPA for 2 minutes. Data are presented as fold change relative to WT (n = 3). Statistical analysis was performed using the Friedman test for multiple comparisons within genotype. *p < 0.05 (C) Representative immunoblot images of phospho-SMAD2 and total SMAD2/3 in iHBECs treated with or without 50 µM LPA for 2 hours in the presence or absence of 10 µM A13. (D) Densitometric quantification of immunoblots shown in (C). Statistical analysis was performed using the Friedman test for multiple comparisons. *p < 0.05
