Figure Lengend Snippet: Left: SHANK 3 gene expression (mRNA levels) showing the efficiency of SHANK3 silencing in control or doxycycline-induced (Dox: +; 72 h) shSHANK3 expressing PANC-1 clones (clones 1C and 4S). Right: Representative immunoblots of the indicated proteins in control or doxycycline-induced sh SHANK3 expressing PANC-1 clones collected three days after induction. Samples were resolved and blotted on duplicate membranes (m#1 and m#2). p-ERK, phospho-ERK1/2 (Thr202/Y204); ERK, total ERK; AKT, total AKT; p-AKT, phospho-AKT S473; cleaved-PARP1, indicative of apoptosis; GAPDH, a loading control.

Figure Lengend Snippet: Phosphorylation of p65 NF-κB and p38 MAPK, and the production of IL-1β and IL-18 in RZJ/IBM cells in response to LPS or MDP. The treatment with LPS or MDP induced the phosphorylation of NF-κB p65 and p38 MAPK in a dose-dependent manner ( A , first and third panels ). The equivalent protein loading of these molecules was confirmed by immunoblotting with anti-NF-κB p65 or anti-p38 MAPK antibodies ( A , second and fourth panels ). The dose-dependent production of pro-IL-1β and pro-IL-18 was also detected in cell lysates ( B , first and third panels ) or culture supernatants ( B , second and fourth panels ) from RZJ/IBM cells that had been stimulated with LPS for 3 days. The secretion of mIL-18 from LPS-treated RZJ/IBM cells into the culture supernatant was also detected ( B , fourth panel ), whereas that of mIL-1β was not ( B , second panel ). MDP exerted a negligible effect on the production of pro-IL-1β ( B , first panel ) and pro-IL-18 ( B , third panel ). GAPDH was used as an internal control ( B , fifth panel ). Blots are representative of three independent experiments.

Article Snippet: The primary antibodies used for immunoblotting were as follows: rabbit monoclonal antibodies against phospho-p38 MAPK (D3F9, Cat. No. #4511), p38 MAPK (D13E1, Cat.

No. #3034, Cell Signaling Technology); biotinylated antibodies against IL-1β (Cat. No. BAF681) and IL-18 (Cat. No. BAF588) (R&D Systems, Inc., Minneapolis, MN); and mouse monoclonal antibodies against GAPDH (MAb 6C5) (Cat. No. 5G4, HyTest Ltd., Turku, Finland).
