Effect of nicotine on association between E2F1 and ARRB1 in human non–small cell lung cancer cells. A) Serum-starved A549 were treated with 1 μM nicotine for 15 minutes, and localization of ARRB1 and E2F1 was analyzed by double-immunoflourescence staining followed by confocal microscopy (×630 magnification, scale bar = 5 μm). The cells were counterstained with the nuclear marker, 4′6-diamidino-2-phenylindole. Overlay of the images show yellow spots indicating colocalization in the bottom right panel. B) Effect of overexpression of pcDNA3-FLAG-rat ARRB1 (wild type) and pcDNA3-HA-E2F1 in HEK293 cells. HEK293 cells were transfected with the above plasmids, and the physical interaction between ARRB1 and E2F1 was analyzed 24 hours after transfection by immunoprecipitation with mouse anti-HA antibody followed by immunoblotting using mouse anti-FLAG antibody. In addition, immunoblot analysis was done for FLAG and HA expression. C) Real-time kinetics of ARRB1–E2F1 interaction upon nicotine treatment of A549 cells. Serum-starved A549 cells were treated with 1 μM nicotine for 15 minutes, 30 minutes, and 1 hour, and the physical interaction between ARRB1 and E2F1 was analyzed by immunoprecipitation–immunoblot assay. Furthermore, the E2F1 immunoprecipitates were immunoblotted for <t>RB1</t> to demonstrate equivalent amount of E2F1. D) Effect of nicotine on the association of ARRB1 and E2F1 in normal lung epithelial cells, NHBEs and SAECs. Quiescent NHBEs and SAECs were treated with 1 μM nicotine for 15 minutes, and the physical interaction between ARRB1 and E2F1 was analyzed by immunoprecipitation–immunoblot analysis. Furthermore, the E2F1 and ARRB1 immunoprecipitates were immunoblotted with E2F1 and ARRB1 to demonstrate equivalent amounts of protein. E) Effect of nicotine on binding of ARRB1 to E2F1, RB1 and EP300. Serum-starved A549 cells were treated with 1 μM nicotine for 2 hours. The binding of ARRB1 to E2F1, EP300, and RB1 was analyzed by immunoprecipitation–immunoblotting experiment. Immunoprecipitation with anti-mouse HA antibody was used as the negative control for the experiment. The above-mentioned immunoprecipitates were immunoblotted for RB1 protein.

The levels of ARRB1–E2F1 complexes and association of E2F1, ARRB1, Ac-H3, and EP300 with BIRC5 promoter in human NSCLC tumors. A) The levels of ARRB1–E2F1 complexes in human NSCLC tumor tissues relative to matched distant normal lung tissues. Tissue lysates were prepared from human NSCLC tumors (n = 8) and matched distant normal lung tissue (n = 8). Immunoprecipitation–immunoblotting analysis was performed to compare the levels of ARRB1–E2F1 complexes in the above lysates. The E2F1 immunoprecipitates were analyzed for the level of RB1 protein by immunoblotting. The NSCLC tumor tissues were also analyzed for levels of E2F1, ARRB1, RB1, and α7-nAChR relative to matched distant normal lung tissue. ACTB was used as a loading control. B) Relative association of E2F1, ARRB1, Ac-H3, and EP300 with BIRC5 promoter in human NSCLC tumor tissue relative to matched distant normal lung tissue. Chromatin immunoprecipitation (ChIP) assays were performed to compare the levels of E2F1, ARRB1, Ac-H3, and EP300 bound to BIRC5 promoter in these tissues. FOS promoter was used as a negative control. Rabbit anti-mouse IgG was used as the irrelevant antibody for all ChIP reactions. The input DNA lane represents one-fifth of the precleared chromatin used in each ChIP reaction. The results presented in this figure are representative of two independent immunoprecipitation–immunoblotting assays. Ab = antibody; IB = immunoblot; IP = immunoprecipitation.

Chromatin immunoprecipitation (ChIP) assays were performed to compare the levels of E2F1, ARRB1, Ac-H3, and EP300 bound to BIRC5 promoter in these tissues. FOS promoter was used as a negative control. Rabbit anti-mouse IgG was used as the irrelevant antibody for all ChIP reactions. The input DNA lane represents one-fifth of the precleared chromatin used in each ChIP reaction. The results presented in this figure are representative of two independent immunoprecipitation–immunoblotting assays. Ab = antibody; IB = immunoblot; IP = immunoprecipitation.

Article Snippet: Mouse anti-human RB1 was purchased from BD Biosciences (San Jose, CA).
