      • donkey anti-rabbit AF594 conjugated antibody (Invitrogen)
      • donkey anti-mouse AF488 conjugated antibody (Invitrogen)
    • diluted 1:500 in blocking solution for 1h at room temperature.
    • Wash sections 1x 5min with PBS containing 1:2000 diluted 1mg/ml DAPI stock solution.
    • Rinse sections 2x with PBS.
    • Mount slides with mounting medium (Dako).
    • Image acquisition with the same exposure and intensity for all IFs.
    Notes
    • Staining of CYP4B1 with ABIN2777006 is visible in mouse WT lung small airway sections but not in negative control sections of naphthalene treated lungs in which club cells must have been depleted by apoptosis.

    • Club cells in the respiratory system are stained by ABIN2777006 in the smaller airways rather than big airways which is consistent with our literature knowledge. The Cyp450 antibody stains the non-ciliated cells, fitting the hypothesis perfectly. Pear-shaped stained cells reaching into the lumen of bronchiole also supports this finding.

    Full Protocol
    • Naphthalene treatment: i.p. application of 200mg per kg body weight (KG) naphthalene dissolved in oil.
    • Denature 100µg total protein for 5min at 95°C in Laemmli SDS sample buffer and subsequently separate them on a denaturing gel SDS-PAGE gel in for 90min at 100V.
    • Transfer proteins onto 0.2µm nitrocellulose membrane in transfer buffer (15% MeOH, Tris 25mM, 86mM, SDS 70mM).
    • Block the membrane with blocking solution (PBS, 5% milk).
    • Incubation with primary
      • rabbit anti-cytochrome P450, family 4, subfamily B, polypeptide 1 (CYP4B1) (N-Term) antibody (antibodies-online, ABIN2777006, lot QC12731-90422) diluted 1:300 or
      • Hsc70 loading control antibody (supplier, product no, lot no) diluted
    • in blocking solution ON at 4°C.
    • Wash membrane 3x with blocking solution.
    • Incubate with secondary donkey anti-rabbit IgG (H+L) peroxidase-conjugated F(ab')2 fragment (Jackson ImmunoResearch) diluted1:10000 in blocking solution for 1h at RT.
    • Wash membrane 3x with PBS, 1x with blocking solution, 2x with PBS.
    • Develop membrane with SuperSignal West femto substrate (Thermo Fisher Scientific, 34095) according to manufacturer’s recommendations, exposure time 25min.
    • Repeat the incubation steps with both antibodies, washes, and revealing the protein bands.
    Notes
    • Staining of Cyp4b1 in murine lung lysates by ABIN2777006 was very weak with considerable background after one incubation of the membranes with the antibody under the described conditions but did show a band of the expected MW at 59kDa. After a second round of incubation with both primary and secondary antibody this band was much stronger compared to the background.

    • The 59kDa band is diminished in lysates taken two days after naphthalene treatment normalized to Hsc70. Its intensity increases again at day three.

    • ABIN2777006 does also reveal a larger band than 59kDa which might represent ubiquitinylated or SUMOylated Cyp4b1. This would be consistent with this band being strongest 2d after the naphthalene treatment.

    Sujet
    CYP4B1 is a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum. In rodents, the homologous protein has been shown to metabolize certain carcinogens, however, the specific function of the human protein has not been determined.This gene encodes a member of the cytochrome P450 superfamily of enzymes.

Two transcript variants encoding slightly different isoforms have been found for this gene.
