Article Title: CHRFAM7A: a human-specific α 7-nicotinic acetylcholine receptor gene shows differential responsiveness of human intestinal epithelial cells to LPS

doi: 10.1096/fj.14-268037

Figure Lengend Snippet: Identification of CHRFAM7A. A) RT-PCR of CHRFAM7A, CHRNA7, and GAPDH of mRNA isolated from human epithelial cell lines reveals the presence of transcripts in HEK (HEK293l and HEK293W), liver cancer (SKHep), ovarian cancer [OvCar8 (2) and OvCar8(6)], pancreatic (PANC1 and DU145), colon cancer (HCT116), prostate cancer (PC3), and lung cancer (H1299) epithelial cells. B) Overlapping the 3′ and 5′sequences obtained with the primer (bold, underlined) from CaCo2 cells revealed the nucleotide sequence of human epidermal CHRFAM7A that has the exons A (blue) and B (red) of FAM7 and the exons 5–10 of CHRNA7 (black), which when translated, reveals the unique 27 amino acid sequence of CHRFAM7A (C) that distinguishes the human-specific gene from the amino termini found in CHRNA7 variants. D) The CHRFAM7A PCR primers shown in the text were selected to detect the nucleotide sequences that encode the unique CHRFAM7A peptide (C), whereas the CHRNA7A primers enable detection of transcript variants 1 and 2 mRNAs that encode α7nAChRs that differ in their amino terminus by the underlined peptide sequence in (D). The common 386 amino acid sequence that is shared by CHRFAM7A and both CHRNA7 variants is shown in (E).

doi: 10.1096/fj.14-268037

Figure Lengend Snippet: CHRFAM7A is expressed in epithelial cells. PC3 cells were transfected with plasmid encoding a CHRFAM7A-DDK fusion protein and the following day lysed and immunoblotted with antibodies to the DDK tag (A). Untransfected cells were used as control, and molecular weights (kiloDaltons) were determined with molecular weight standards. In (B), RT-PCR was used to detect CHRNA7 and CHRFAM7A expression in gut 1) CaCo2, 2) KM12, 3) HT29, 4) KM20, 5) LS174, 6) HCT116, 7) SW24, and 8) Colo205 epithelial cells. In 3 instances (CaCoT, HCT116T, and KM20L), the same cell line from 2 alternative sources was analyzed. As shown in (C) and (D), both CHRNA7 and CHRFAM7A were measured by qRT-PCR and the relative expression levels compared to that measured in CaCo2 cells.

Figure Lengend Snippet: Differential regulation of CHRNA7 and CHRFAM7A by LPS treatment of gut epithelial cells. Triplicate cultures of 1) CaCo2, 2) KM12, 3) HT29, 4) KM20, 5) LS174, 6) HCT116, 7) SW24, 8) Colo205, and 9) FHs or T84 epithelial cells were treated for 3 hours with LPS as described in the text. A) The effects of LPS on CHRNA7 gene expression measured by qPCR, normalized to GAPDH, and changes from controls assessed using the ∆∆Ct method. B) The cDNA prepared from the same cell lysates was assessed for CHRFAM7A gene expression. In (C) and (D), the ratios of CHRFAM7A expression to CHRNA7 in control and LPS-stimulated cells were compared.
