Figure Lengend Snippet: qPCR detection of α, β, γENaC, and ASIC1‐5 transcript expression in cultured bone marrow derived macrophages and freshly isolated monocytes from male and female mice. Macrophages were cultured in the presence of 20 ng/mL of CSF1. (a) PCR reactions from macrophages were separated on 3%–4% agarose gels to determine if amplicon of expected size was present (identified by arrowhead in samples with >1 product). 100 ng RNA template equivalent was used for all reactions except ASIC1, where 1000 ng was used. Three primer pair‐probe sets were tested on ASIC2 and ASIC1. The primer pair‐probe sets shown amplified a band at the expected size, in addition to 1–2 other bands. (b) Macrophage C th 's individual ENaC and ASIC transcripts from bone marrow derived macrophages 3 replicates in n = 2 trials. Thresholds at or near 35 cycles were consistently identified in all replicates for αENaC and ASIC3. Thresholds less than 39 cycles were identified for βENaC and ASIC2. γENaC amplified in only 1/6 and 4/6 replicates in male and female samples, respectively. (c) Bone marrow derived freshly isolated monocytes C th 's for individual ENaC and ASIC subunits using 75 ng RNA template equivalent. Samples from four animals were pooled. (d) Bone marrow derived freshly isolated monocyte Western blot detection of αENaC and βENaC. Samples were pooled from four animals. *Indicates statistical difference between male and female at p < 0.05 using an Uncorrected Fisher LSD Test.

Article Title: Bone marrow monocytes and macrophages from mice lacking βENaC and ASIC2 have a reduced chemotactic migration response and polarization

doi: 10.14814/phy2.16139

Figure Lengend Snippet: Loss of βENaC or ASIC2 inhibits bone marrow monocyte chemotactic migration. Chemotactic migration is attenuated in freshly isolated bone marrow monocytes from (a, b) βENaC hypomorph mice (βENaC m/m , 10–13 weeks of age) or (c, d) ASIC2 global knockout mice (ASIC2 −/− , 7–8 weeks of age). Monocytes were isolated in parallel from an age‐matched wildtype and modified animal within a sex then migrated overnight. Mice were used between 7 and 13 weeks of age. These findings suggest (1) migration responses in wildtype mice are greater in female versus males, and (2) βENaC and ASIC2 both contribute to migration, but differentially in the sexes. Loss of βENaC had a larger impact on migration in female versus male, while loss of ASIC2 had a larger impact in males. Normalized migration data are shown in Figure Representative images are shown in panels a and c and group data are shown in panels b and d. Data are mean ± SEM and represent seven FOVs from three insets ( n = 21) and were analyzed using two‐way ANOVA followed by Holm‐Sidak post hoc test. p values of main factors and their interaction and differences among groups are shown on the graph and demonstrate confidence.

Figure Lengend Snippet: Loss of ASIC2 plus βENaC on bone marrow monocyte chemotactic migration is not additive. Chemotactic migration in freshly isolated bone marrow from mice homozygous for ASIC2 global knockout and βENaC hypomorph alleles (ASIC2 −/− /βENaC m/m , 6–7 weeks). Monocytes were isolated in parallel from an age‐matched wildtype and modified animal within a sex then migrated overnight. Representative images of underside of migration membrane (a) and group data (b) in males are shown. These findings suggest (1) migration responses in wildtype mice are greater in female versus male, and (2) βENaC plus ASIC2 both contribute to migration, but greater impact on female. Loss of βENaC had a larger impact on migration in female versus male, while loss of ASIC2 had a larger impact in males. (c). Normalized migration data in monocytes from βENaC m/m , ASIC2 −/− , and ASIC2 −/− /βENaC m/m mice are shown. Both data sets are presented as mean ± SEM and represent seven FOVs from three insets ( n = 21, except wildtype control in C where n = 21 FOVs from n = 9 inserts) and were analyzed using 2‐way ANOVA followed by Holm‐Sidak post hoc test. p values of main factors and their interaction and differences among groups are shown on the graph and demonstrate confidence.

Figure Lengend Snippet: Bone marrow macrophages from mice lacking ASIC2 plus βENaC (ASIC2 −/− /βENaC m/m , KO) are polarized towards an M1 phenotype. (a) Migration of bone marrow derived macrophages from ASIC2 −/− /βENaC m/m mice are inhibited to 55% and 65% of WT control cells from females and males, respectively. Data were analyzed using 2‐way ANOVA followed by Holm‐Sidak post hoc test. (b) Fold expression of monocyte/macrophage marker message in cultured bone marrow macrophages from males. The myeloid origin marker CD68 was decreased and M1 macrophage marker CD86 was upregulated in KO cells. The M2 marker CD206 was not significantly elevated. CD163, another marker of M2 macrophages, did not amplify in any samples. (c) Media soluble TNFα, released from M1 macrophages, was elevated in KO cell culture media. Samples were obtained from two wells from three different cell lines. Data in Panels b and d were analyzed using independent/unpaired, 2‐tailed t ‐tests. Representative images (d) and group data (e) from semiquantitative immunolabeling of CD86 and CD206 in cells show CD86, but not CD206, are elevated in KO cells. each data point represents a cluster of cells, n = 5–6 cell clusters from n = 3 images. Fluorescence is normalized to cell area. Data in panels e and f analyzed using 1‐way ANOVA followed by the Holm‐Sidak post hoc test. These findings suggest bone marrow macrophages from mice lacking βENaC and ASIC2 are polarized towards the M1 phenotype. All data are mean ± SEM. P values are provided to demonstrate confidence.

Figure Lengend Snippet: Does rescue of ASIC2 or βENaC in bone marrow macrophages from ASIC2 −/− /βENaC m/m mice restore the chemotactic migration response and polarization marker expression? ASIC2 −/− /βENaC m/m (KO) male cell lines were transfected with ECFP_mouse ASIC2 or EGFP_mouse βENaC full length constructs and maintained in the presence of selection antibiotic G418 (except WT control and KO control). (a) Rescue of either ASIC2 or βENaC partially rescues the chemotactic migration response in macrophages lacking ASIC2 and βENaC. Migration data points represent 42–63 FOVs from n = 2 to 3 inserts from three trials. (b) The monocyte origin marker CD68 (b) increased with rescue of ASIC2a and M1 macrophage marker CD86 decreased (c, d), consistent with the decrease in CD68 and increase in CD86 in KO versus WT macrophages (Figure ). The C Th for GAPDH, CD68, and CD86 in KO‐EGFP control samples are within range to detect increases or decreases (20, 20, and 32, respectively). CD163 were not consistently detected in the three replicates from 2 to 5 independent trials. (d). Immunolabeling of CD86‐Viobright 515 in KO macrophages rescued with βENaC or ASIC2 are consistent with qPCR findings. Fluorescence signal of CD86 was greater than baseline EGFP/ECFP signal assessed in separate samples (not shown). (e) Soluble TNFα in the media of cultured macrophages (72 h) was decreased in βENaC, but increased in ASIC2 rescued macrophages. All data are mean ± SEM. Migration data were analyzed using 1‐way ANOVA followed by Holm‐Sidak post hoc test. Quantitative PCR were analyzed using a 1‐way ANOVA followed by Dunnett post hoc test. p values are provided to demonstrate confidence.

Figure Lengend Snippet: qPCR detection of α, β, γENaC, and ASIC1‐5 transcript expression in cultured bone marrow derived macrophages and freshly isolated monocytes from male and female mice. Macrophages were cultured in the presence of 20 ng/mL of CSF1. (a) PCR reactions from macrophages were separated on 3%–4% agarose gels to determine if amplicon of expected size was present (identified by arrowhead in samples with >1 product). 100 ng RNA template equivalent was used for all reactions except ASIC1, where 1000 ng was used. Three primer pair‐probe sets were tested on ASIC2 and ASIC1. The primer pair‐probe sets shown amplified a band at the expected size, in addition to 1–2 other bands. (b) Macrophage C th 's individual ENaC and ASIC transcripts from bone marrow derived macrophages 3 replicates in n = 2 trials. Thresholds at or near 35 cycles were consistently identified in all replicates for αENaC and ASIC3. Thresholds less than 39 cycles were identified for βENaC and ASIC2. γENaC amplified in only 1/6 and 4/6 replicates in male and female samples, respectively. (c) Bone marrow derived freshly isolated monocytes C th 's for individual ENaC and ASIC subunits using 75 ng RNA template equivalent. Samples from four animals were pooled. (d) Bone marrow derived freshly isolated monocyte Western blot detection of αENaC and βENaC. Samples were pooled from four animals. *Indicates statistical difference between male and female at p < 0.05 using an Uncorrected Fisher LSD Test.

doi: 10.14814/phy2.16139

Figure Lengend Snippet: Loss of βENaC or ASIC2 inhibits bone marrow monocyte chemotactic migration. Chemotactic migration is attenuated in freshly isolated bone marrow monocytes from (a, b) βENaC hypomorph mice (βENaC m/m , 10–13 weeks of age) or (c, d) ASIC2 global knockout mice (ASIC2 −/− , 7–8 weeks of age). Monocytes were isolated in parallel from an age‐matched wildtype and modified animal within a sex then migrated overnight. Mice were used between 7 and 13 weeks of age. These findings suggest (1) migration responses in wildtype mice are greater in female versus males, and (2) βENaC and ASIC2 both contribute to migration, but differentially in the sexes. Loss of βENaC had a larger impact on migration in female versus male, while loss of ASIC2 had a larger impact in males. Normalized migration data are shown in Figure Representative images are shown in panels a and c and group data are shown in panels b and d. Data are mean ± SEM and represent seven FOVs from three insets ( n = 21) and were analyzed using two‐way ANOVA followed by Holm‐Sidak post hoc test. p values of main factors and their interaction and differences among groups are shown on the graph and demonstrate confidence.

Figure Lengend Snippet: Loss of ASIC2 plus βENaC on bone marrow monocyte chemotactic migration is not additive. Chemotactic migration in freshly isolated bone marrow from mice homozygous for ASIC2 global knockout and βENaC hypomorph alleles (ASIC2 −/− /βENaC m/m , 6–7 weeks). Monocytes were isolated in parallel from an age‐matched wildtype and modified animal within a sex then migrated overnight. Representative images of underside of migration membrane (a) and group data (b) in males are shown. These findings suggest (1) migration responses in wildtype mice are greater in female versus male, and (2) βENaC plus ASIC2 both contribute to migration, but greater impact on female. Loss of βENaC had a larger impact on migration in female versus male, while loss of ASIC2 had a larger impact in males. (c). Normalized migration data in monocytes from βENaC m/m , ASIC2 −/− , and ASIC2 −/− /βENaC m/m mice are shown. Both data sets are presented as mean ± SEM and represent seven FOVs from three insets ( n = 21, except wildtype control in C where n = 21 FOVs from n = 9 inserts) and were analyzed using 2‐way ANOVA followed by Holm‐Sidak post hoc test. p values of main factors and their interaction and differences among groups are shown on the graph and demonstrate confidence.

Figure Lengend Snippet: Bone marrow macrophages from mice lacking ASIC2 plus βENaC (ASIC2 −/− /βENaC m/m , KO) are polarized towards an M1 phenotype. (a) Migration of bone marrow derived macrophages from ASIC2 −/− /βENaC m/m mice are inhibited to 55% and 65% of WT control cells from females and males, respectively. Data were analyzed using 2‐way ANOVA followed by Holm‐Sidak post hoc test. (b) Fold expression of monocyte/macrophage marker message in cultured bone marrow macrophages from males. The myeloid origin marker CD68 was decreased and M1 macrophage marker CD86 was upregulated in KO cells. The M2 marker CD206 was not significantly elevated. CD163, another marker of M2 macrophages, did not amplify in any samples. (c) Media soluble TNFα, released from M1 macrophages, was elevated in KO cell culture media. Samples were obtained from two wells from three different cell lines. Data in Panels b and d were analyzed using independent/unpaired, 2‐tailed t ‐tests. Representative images (d) and group data (e) from semiquantitative immunolabeling of CD86 and CD206 in cells show CD86, but not CD206, are elevated in KO cells. each data point represents a cluster of cells, n = 5–6 cell clusters from n = 3 images. Fluorescence is normalized to cell area. Data in panels e and f analyzed using 1‐way ANOVA followed by the Holm‐Sidak post hoc test. These findings suggest bone marrow macrophages from mice lacking βENaC and ASIC2 are polarized towards the M1 phenotype. All data are mean ± SEM. P values are provided to demonstrate confidence.

Figure Lengend Snippet: Does rescue of ASIC2 or βENaC in bone marrow macrophages from ASIC2 −/− /βENaC m/m mice restore the chemotactic migration response and polarization marker expression? ASIC2 −/− /βENaC m/m (KO) male cell lines were transfected with ECFP_mouse ASIC2 or EGFP_mouse βENaC full length constructs and maintained in the presence of selection antibiotic G418 (except WT control and KO control). (a) Rescue of either ASIC2 or βENaC partially rescues the chemotactic migration response in macrophages lacking ASIC2 and βENaC. Migration data points represent 42–63 FOVs from n = 2 to 3 inserts from three trials. (b) The monocyte origin marker CD68 (b) increased with rescue of ASIC2a and M1 macrophage marker CD86 decreased (c, d), consistent with the decrease in CD68 and increase in CD86 in KO versus WT macrophages (Figure ). The C Th for GAPDH, CD68, and CD86 in KO‐EGFP control samples are within range to detect increases or decreases (20, 20, and 32, respectively). CD163 were not consistently detected in the three replicates from 2 to 5 independent trials. (d). Immunolabeling of CD86‐Viobright 515 in KO macrophages rescued with βENaC or ASIC2 are consistent with qPCR findings. Fluorescence signal of CD86 was greater than baseline EGFP/ECFP signal assessed in separate samples (not shown). (e) Soluble TNFα in the media of cultured macrophages (72 h) was decreased in βENaC, but increased in ASIC2 rescued macrophages. All data are mean ± SEM. Migration data were analyzed using 1‐way ANOVA followed by Holm‐Sidak post hoc test. Quantitative PCR were analyzed using a 1‐way ANOVA followed by Dunnett post hoc test. p values are provided to demonstrate confidence.
