Production of LPP in cells. (A) Scheme of the subdomain structure of the human zyxin, LPP, and TRIP6 proteins. All three proteins are composed of an N-terminal proline-rich domain (white box) and a C-terminal cysteine-rich portion composed of three LIM domains (gray boxes). LPP and zyxin contain FPPPP motifs in their N-terminal proline-rich domain (small boxes). (B) Specificity of anti-LPP antibodies. Total HeLa cell extracts were analyzed by SDS-PAGE and Western blotting with MP2, a serum directed against a synthetic LPP-derived peptide not present in zyxin or TRIP6 (amino acids 318–332; lane 1), with LPP2, an affinity-purified polyclonal antibody directed against a recombinant fusion protein containing amino acids 3–414 of LPP (GST-LPP3–414; lane 2), or with a monoclonal anti-zyxin antibody (lane 3). Note that zyxin migrates slower than LPP, confirming that LPP-specific antibodies do not recognize zyxin. The positions of molecular mass markers (kilodaltons) are shown on the left. (C) Expression of LPP in different human cells. Cell extracts were prepared from the following human cells and cell lines: foreskin fibroblasts (HFF), cervix carcinoma (HeLa), <t>keratinocytes</t> (Kera.), platelets (plat.), lymphocytes (HL60), and colon carcinoma (CaCo2). Approximately 15 μg of protein from each extract was analyzed by SDS-PAGE and Western blotting with MP2. The positions of molecular mass markers (kilodaltons) are shown on the left. (D) Quantitation of LPP and zyxin proteins in extracts from HFF, CaCo2, and LLC-PK1 cell lines. Values were obtained by quantifying LPP- or zyxin-specific protein bands with the use of a Cy5-based detection method (see MATERIALS AND METHODS). aThese values have been published elsewhere (Fradelizi et al., 1999 ) but are shown here for comparison.

( A ) RT-qPCR was utilized to measure HCoV-229E viral RNA levels in MRC-5 cells, with results normalized to 18S RNA at various infection stages. ( B ) MRC-5 cells were infected with HCoV-229E at an MOI of 10 for a day, followed by 7 days of incubation period. Cell extracts were taken daily for RT-qPCR analysis (normalized to 18S RNA) and Western blotting (normalized to tubulin). Results are expressed as means ± SEM. ( C, D ) In a similar setup, MRC-5 cells were infected with HCoV-OC43 at an MOI of 10. ( E, F ) Another experiment was conducted using Caco-2-derived <t>C2BBe1</t> cells infected with HcoV-NL63 at an MOI of 10. The results from these experiments represent data from three independent trials.

Intracellular distribution of LPP in cultured cells. Cells were fixed, detergent permeabilized, and doubly stained by indirect immunofluorescence. (A–D) HFF cells doubly stained with affinity-purified LPP2 antibody (A and C) and with either monoclonal anti-vinculin (B) or anti-zyxin (D) antibody. Views were obtained by epifluorescence microscopy. The insets show 2.2-fold magnified details of images C and D. Ventral faces of the cells are shown. (E and F) Keratinocytes doubly stained with affinity-purified LPP2 antibody (E) and with monoclonal anti-vinculin antibody (F). Views were obtained by confocal laser scanning microscopy. Three apical sections were compiled. LPP codistributes with vinculin, which was used as a marker for focal adhesions (B) and cell-to-cell contacts (F). Note that in contrast to LPP, zyxin staining is not restricted to focal adhesions but is also found along actin stress fibers (D). LPP2 staining is also visible in the nucleus. Bars, 20 μm.
