Fig 1: The effects of forskolin on NF-κB expression in LPS-treated RT4-D6P2T cells.The immortalized rat RT4-D6P2T Schwann cell line (ATCC #CRL-2768) was treated with 0.1, 1, or 10 μg/mL of LPS in N2 media, with or without 2 μM of forskolin (+/- Fsk), for 3 hours. SDS-PAGE gel electrophoresis and Western blotting were performed using prepared cell lysates. NF-κB expression was visualized using enhanced chemiluminescence reagent and quantified via densitometry analysis using Bio Rad Image software. Actin was used as a loading control, and detected expression levels of actin were used to normalize all Western blots. The above blots are representative blots from three independent experiments that were spliced together, as indicated by the vertical black lines. Relative band densities are displayed as mean fold change (over the N2 control [no LPS]) ± SEM. The dotted line indicates a fold change of 1, with a fold change above 1 representing increased protein expression and a fold change below 1 representing decreased protein expression compared to the N2 control. Results from three independent experiments were examined using one-way ANOVA and tested with Tukey’s and LSD post-hoc analysis in R Studio. There was no significant difference in mean fold change between the various doses of LPS (F = 0.240, df = 1, p = 0.635) (n = 3).
Fig 2: The effects of forskolin on AKAP95 expression in LPS-treated RT4-D6P2T cells.The immortalized rat RT4-D6P2T Schwann cell line (ATCC #CRL-2768) was treated with 0.1, 1, or 10 μg/mL of LPS in N2 media, with or without 2 μM of forskolin (+/- Fsk), for 3 hours. SDS-PAGE gel electrophoresis and Western blotting were performed using prepared cell lysates. AKAP95 expression was visualized using enhanced chemiluminescence reagent and quantified via densitometry analysis using Bio Rad Image software.

Results from three independent experiments were examined using one-way ANOVA and tested with Tukey’s and LSD post-hoc analysis in R Studio. There was no significant difference in mean fold change between the various doses of LPS (F = 0.151, df = 1, p = 0.706) (n = 3).

SDS-PAGE gel electrophoresis and Western blotting were performed using prepared cell lysates.

Fig 5: The effects of forskolin on TNF-α secretion by LPS-treated RT4-D6P2T cells.The immortalized rat RT4-D6P2T Schwann cell line (ATCC #CRL-2768) was treated with 0.1, 1, or 10 μg/mL of LPS in N2 media, with or without 2 μM of forskolin, for 3 hours. The Invitrogen Rat TNF alpha ELISA kit (RayBiotech) was used to quantify the TNF-α concentration (pg/mL) in media samples, which is displayed as mean fold change ± SEM. The dotted line indicates a fold change of 1, with a fold change above 1 representing increased TNF-α secretion and a fold change below 1 representing decreased TNF-α secretion compared to the N2 control.
