anti hBD 3 antibodies were utilized in all other experiments. Synthetic hBD 3 was purchased from PeproTech. Alkaline phosphatase conjugated goat anti rabbit antibody was from Pierce Biotechnology. Decitabine SLPI antibodies, control antibodies, and neutralizing antibodies against TGF ??and HB EGF were purchased from R D Systems. Neutralizing antibodies against EGFR were obtained from EMD. The anti NGAL antibodies were described previously . PD 168383 was purchased from EMD and AG 1478 from Sigma Aldrich. Skin specimens. Skin specimens were obtained as excess healthful tissue from skin surgery, under protocols approved by the Institutional Review Board at UCLA along with the Ethics Committee at Lund University. The surgical specimens were cut into slices of 1 ??10 mm and grown in serum free keratinocyte medium from Cambrex supplemented with transferrin, hEGF , 0.
5 mg ml hydrocortisone, gentamicin, amphotericin Decitabine B, and epinephrine but with out insulin. We previously discovered that this medium does not induce the expression of AMP in keratinocytes . In the inhibition experiment, the skin slices were incubated with blocking antibodies at a final concentration of 15 ?g ml, 50 ?M TAPI 1 , 10 ?g ml CRM197 , 0.2 trypsin inhibitory units of aprotinin , and 5 ?g ml E 64 . Human skin wounds. Samples from human skin wounds were obtained under protocols approved by the Ethics Committee at Lund University. A skin wound was induced by a punch biopsy on the upper arm of healthful male volunteers after informed consent. Right after 4 days, new punch biopsies were taken from the edges from the initial biopsy.
Extraction of AMPs from skin and medium. Skin slices were homogenized in 1 M HCl and incubated for 24 hours at 4 C under rotation, followed by centrifugation at 10,000 g. The pellets were incubated 2 additional occasions with 5 acetic acid, followed by centrifugation at 10,000 g. Supernatants were collected, lyophilized, and resuspended in 1 ml of distilled Doxorubicin H2O. The resuspended supernatants were PARP pooled and diluted to a total volume of 20 ml in distilled H20. The pH was adjusted to 7, along with the sample was incubated at space temperature with MacroPrep CM Support beads equilibrated in 25 mM ammonium acetate for 3 4 hours. The beads were subsequently washed, along with the bound material was eluted with 5 acetic acid. The eluate was lyophilized and resuspended in 0.01 acetic acid and desalted and con centrated using Microcon filter with molecular cutoff at 3 kDa.
The retentate was lyophilized and resuspended in 50 ?l 0.01 acetic acid. AU Page, SDS Page, and immunoblotting were performed in accordance with the manufacturer’s directions . Right after transfer of proteins from the polyacrylamide gels, the PVDF membrane was fixed for 30 minutes in tris buffered saline with 0.05 glutaraldehyde and blocked with Superblock Blocking Buffer Doxorubicin . For visualization from the poly , the PVDF membranes were incubated overnight with primary Abs. The following day, the membranes were incubated for 2 hours with HRP conjugated secondary Abs and visualized by Immun Star HRP luminal enhancer and Immun Star peroxide buffer . The PVDF membrane was stripped for 20 minutes in 0.2 M Glycine and 1 SDS, washed twice with TBS with 0.
05 Tween 20, and finally blocked before incubating overnight with a different antibody. Stimulation and wounding of organotypic epidermal cultures. Principal epidermal cultures Decitabine EPI 200 3S containing human epidermal keratinocytes were grown on collagen coated Millicell CM Membranes . The cultures were placed in 12 well plates with media supplied by the manufacturer. On day 4, the epidermal cultures were lifted towards the air liquid interface and after that cultured in air liquid interface for a different 4 days in accordance with the manufacturer’s directions. On day 2 after airlifting the cultures, the medium was changed to medium with out insulin or EGF and with out antibiotics. On day 4 after airlifting, the cultures were stimulated with TGF ?? . Cells were harvested after 48 hours of stimulation.
The cultures were homogenized in 1 M HCl and sonicated on ice 3 occasions for 10 seconds each time. The samples were incubated for 24 hours at 4 C under rotation, followed by centrifugation at 10,000 Doxorubicin g. The supernatants were collected and lyophilized and resuspended in 400 ?l of distilled H2O. The remedy was desalted and concentrated using Microcon filter with a molecular cutoff at 3 kDa. The eluate was finally resuspended in 50 ?l of 0.01 acetic acid. This material was subsequently utilized for antibacterial assays. For the in vitro wounding experiments, EPI 200 cultures were utilized. The cultures were wounded by a sterile scalpel. Samples were processed for IHC 3 and 4 days after wounding. RNA isolation. Total RNA was isolated with Tri zol in accordance with the recommendations from the manufacturer. The RNA was double purified with Tri zol, then precipitated with ethanol and resuspended in 0.1 mM EDTA. The concentration was determined by spectrophotometric measurement along with the integrity from the RNA assessed by running a sample on a
