Juxtamembrane 2 (JM2) is not cytotoxic. Human <t>microvascular</t> endothelial cells <t>(HMVECs)</t> were treated with JM2 at 12.5, 25, 50, 100, and 200 μM concentrations for 2 h at 37°C, 5% CO2. The media were then sampled for lactate dehydrogenase (LDH) as a marker for cell death. No significant differences were observed between control (No Peptide) and any concentration of JM2. n = 3, with each n representing the average of 3 replicates; error bars represent SE.

JM2 specifically enhances connexin43 (Cx43)-β-tubulin interaction. A and B: Cx43-HeLa cell lysates were incubated with β-tubulin-glutathione S-transferase (GST) bound to glutathione-Sepharose beads plus vehicle (H2O; Veh) or 25 μM JM2. Eluted proteins were analyzed by immunoblotting for Cx43 (A) or β-tubulin (B). β-Tubulin pulled down Cx43 in control conditions (vehicle), and this was increased in the presence of JM2 (A, “β-tubulin Pull-Down”), indicating that JM2 specifically enhances the interaction between Cx43 and β-tubulin. This was supported by the observation that the input amounts of Cx43 and β-tubulin subjected to pull-down were equivalent between Veh and JM2 treatments (A and B “Input” blots, respectively) and that JM2 did not affect the amount of β-tubulin pulled down by a β-tubulin antibody (B, “β-tubulin Pull-Down”). C: HMVECs were treated for 2 h with either vehicle (H2O; “Veh”), 50 μM JM2, or 50 μM control peptide (CP). Cells were fixed and labeled for Cx43-β-tubulin interaction (green), and the nucleus (blue). Differential interference contrast (DIC; gray scale) was used to approximate cell-cell borders (dashed lines). Boxed regions indicate the location of the enlarged insets. Scale bar = 10 μm. D: Cx43-β-tubulin interaction was quantified as the number of Duolink signals detected per cell. The number of signals detected in JM2-treated cells was significantly greater than in vehicle (Veh) or control peptide (CP). n = 3, with each n representing the average of 5 replicates; error bars represent SD. Nonlinear level adjustments were applied to Western blot images to enhance visibility. ****P < 0.001.

JM2 decreases gap junction (GJ) size while increasing labeling for microtubules. HMVECs were treated for 2 h with either vehicle (H2O; “Veh”) or 50 μM JM2. A: cells were fixed and labeled for Cx43 (cyan), α-tubulin (yellow), and the nucleus (magenta); Scale bar = 10 μm. B: total Cx43 fluorescence was unaffected by JM2. C and D: similarly, GJ number was measured and found to be unaffected by JM2 (C), while there was a significant decrease in the level of cell border-associated Cx43 fluorescence (D). E: consistent with the reduction in cell border Cx43 fluorescence, GJ size was reduced. F: concomitantly, the level of intracellular Cx43 fluorescence was significantly increased in JM2-treated cells. G: microtubule fluorescence was also significantly increased by JM2 treatment. For all graphs, n = 3, with each n representing the average of 5 replicates; error bars represent SD. *P < 0.05, **P < 0.01.

JM2 increases the accumulation of Cx43-containing secretory vesicles. HMVECs were treated for 2 h with either vehicle (H2O; “Veh”) or 50 μM JM2. A: cells were fixed and labeled for Cx43 (red), the trans-Golgi network (TGN) protein TGN38 (green), and the nucleus (blue). Arrows indicate a number of puncta with Cx43 TGN38 colocalization that are likely secretory vesicles; Scale bar = 10 μm. B–D: colocalization of Cx43 and TGN38 was significantly increased by JM2 as assessed by Pearson’s coefficient (B), the amount of colocalized pixels as a % of total Cx43 pixels (C), and the amount of colocalized pixels as a % of total TGN38 pixels (D); n = 3, with each n representing the average of 3 replicates; error bars represent SD. *P < 0.05, **P < 0.01.

JM2 treatment inhibits both gap junction intercellular communication and hemichannel function. A: HMVECs were treated with either vehicle (H2O and EtOH), 50 μM JM2, or 50 μM flufenamic acid (FFA) for 2 h, and calcein-AM was loaded during the final 30 min. Selected cells (arrows) were then photobleached by high-intensity laser light and recovery was monitored. Scale bar = 20 μm. B: average fluorescence readings were plotted over time. n = 3, with each n representing the average of 3 replicates; error bars represent SE. C and D: nonlinear regression to an exponential decay function was used to determine the maximum predicted recovery (F∞; C) and the recovery rate constant (k; D). Error bars represent SD. E: connexin43 (Cx43) and and wild-type (WT) HeLa cells were treated with either vehicle (H2O and EtOH; “Veh”), 50 μM JM2, 50 μM FFA, or 5 μM mefloquine (MFQ) for 2 h, then exposed to ethidium bromide (EtBr) for 15 min. Cells were fixed and imaged, and the quantified relative fluorescence is displayed. Dashed line indicates the level of autofluorescence in Cx43-HeLa cells. F: HMVECs were treated, imaged, and quantified as in E. For graphs in E and F, n = 4, with each n representing the average of 5 replicates; error bars represent SD. *P < 0.05, **P < 0.01, ***P< 0.001, ****P < 0.001.
