    <t>HDAC2</t> enhances antimicrobial activities against E.coli in mice. (A) Bacterial loads in the blood were calculated in HDAC2-knockout and wild type mice. (A)The picture of the bacterial clones was taken by BIO-RAD ChemiDoc“MP Imaging System. (B)The number of colony-forming units (CFU) in the blood of mice was calculated. HDAC2 WT and HDAC2 KO mice were administrated with E. coli- GFP (5 × 10 7 ) by intravenous Injection. Blood (20 μl) was taken from the tail vein of the mice, applied to the pretreated solid MHA medium, and incubated at 37 °C for 20 h. Count the colonies on the culture medium and take pictures. The experiments were performed in quintuplicate, data are presented as the means ± SEM. of independent experiments. *P < 0.05, **P < 0.01 (two-tailed Student’s t -test). (B) Bacterial loads in the kidneys were calculated in HDAC2-knockout and wild type mice. The picture of kidneys from HDAC2 WT and HDAC2 KO mice were taken. The number of colony-forming units (CFU) in the kidneys of mice was calculated. The kidneys from HDAC2 KO and HDAC2 WT mice were weighed, ground, spread on the MHA plates, incubated for 16–24 h at 37 °C, and then bacterial clones were counted. The experiments were performed in quintuplicate, data are presented as the means ± SEM. of independent experiments. *P < 0.05, **P < 0.01 (two-tailed Student’s t -test). n = 5 mice per group. (C) H&E staining of livers and kidneys. The arrows indicate damage section of tissue. (D) Serum <t>CRP</t> and PCT levels of mice with E. coli- GFP bacteremia at 24 h. The CRP and PCT were measured by ELISA. Data are shown as mean ± SEM. *p < 0.05; n = 5 mice per group. ns, not significant.

    (A) Protein diagram. VP1u-APEX2 consists of APEX2 fused to <t>the</t> <t>C-terminus</t> of the unique region of B19V VP1 (VP1u) via a seven-residue glycine-serine linker (GGSGGSG), followed by a Flag tag and a 6 × Histidine (His) tag. APEX2 has a linker-Flag-His tag fused at the C-terminus. (B) Analysis of purified proteins. VP1u-APEX2 and APEX2 proteins were expressed in bacteria and purified. Approximately (∼) 1 µg of each protein was separated by SDS-PAGE, followed by Coomassie blue staining. M, molecular weight marker. (C) Confocal microscopy of VP1u-APEX2 entry. 1 × 10 6 UT7/Epo-S1 cells were incubated with 2 μM VP1u-APEX2 or APEX2 protein at 37°C for 2 h. The cells were then immunostained with α-Flag to visualize internalized proteins under a Leica STED confocal microscope. Scale bar = 10 μm. Nuclei were stained with DAPI (4’,6-diamidino-2-phenylindole). (D) Western blotting of APEX2-biotinylated proteins. 1 × 10 7 UT7/Epo-S1 cells were incubated with 2 μM VP1u-APEX2 or APEX2 protein at 37°C. After 2 h, APEX2-mediated biotinylation was then performed as described in the Materials and Methods and Figure S1 . Biotinylated host proteins were purified with streptavidin-conjugated magnetic beads. The supernatant was collected as the flow-through (FT), and the beads were further washed several times and eluted as the pull-down (PD). Both FT and PD samples were analyzed by SDS-PAGE and immunoblotting using Alexa Fluor 680-conjugated streptavidin. (E) Analysis of VP1u-APEX2-biotinylated/associated proteins using quantitative mass spectrometry (qMS). Three independent PD samples prepared from VP1u-APEX2 and APEX2 (control) treated cells were analyzed by on-bead digestion and qMS. MS data were processed and analyzed as described in the Materials and Methods. The bubble plot shows protein enrichment (log 2 fold change) in the VP1u-APEX2 group relative to the APEX control, with color indicating subcellular localization based on Gene Ontology (GO) annotation. TFRC denotes human transferrin receptor 1 (hTfR).

(D) Western blotting of APEX2-biotinylated proteins. 1 × 10 7 UT7/Epo-S1 cells were incubated with 2 μM VP1u-APEX2 or APEX2 protein at 37°C. After 2 h, APEX2-mediated biotinylation was then performed as described in the Materials and Methods and Figure S1 . Biotinylated host proteins were purified with streptavidin-conjugated magnetic beads. The supernatant was collected as the flow-through (FT), and the beads were further washed several times and eluted as the pull-down (PD). Both FT and PD samples were analyzed by SDS-PAGE and immunoblotting using Alexa Fluor 680-conjugated streptavidin. (E) Analysis of VP1u-APEX2-biotinylated/associated proteins using quantitative mass spectrometry (qMS). Three independent PD samples prepared from VP1u-APEX2 and APEX2 (control) treated cells were analyzed by on-bead digestion and qMS. MS data were processed and analyzed as described in the Materials and Methods. The bubble plot shows protein enrichment (log 2 fold change) in the VP1u-APEX2 group relative to the APEX control, with color indicating subcellular localization based on Gene Ontology (GO) annotation. TFRC denotes human transferrin receptor 1 (hTfR).

    Figure Lengend Snippet: (A) Protein diagram. VP1u-APEX2 consists of APEX2 fused to the C-terminus of the unique region of B19V VP1 (VP1u) via a seven-residue glycine-serine linker (GGSGGSG), followed by a Flag tag and a 6 × Histidine (His) tag. APEX2 has a linker-Flag-His tag fused at the C-terminus. (B) Analysis of purified proteins. VP1u-APEX2 and APEX2 proteins were expressed in bacteria and purified. Approximately (∼) 1 µg of each protein was separated by SDS-PAGE, followed by Coomassie blue staining. M, molecular weight marker. (C) Confocal microscopy of VP1u-APEX2 entry. 1 × 10 6 UT7/Epo-S1 cells were incubated with 2 μM VP1u-APEX2 or APEX2 protein at 37°C for 2 h.

HDAC2 WT and HDAC2 KO mice were administrated with E. coli- GFP (5 × 10 7 ) by intravenous Injection. Blood (20 μl) was taken from the tail vein of the mice, applied to the pretreated solid MHA medium, and incubated at 37 °C for 20 h. Count the colonies on the culture medium and take pictures.
