- Western blot analysis of Septin-8 was performed by separating 10 µg of various tissue extracts by 10% SDS-PAGE. Proteins were transferred to a membrane and probed with a Septin-8 Polyclonal Antibody (Product # PA5-31356) at a dilution of 1:4000. The HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody.

- Figure 5 Data implicating Sept8/ SEPTIN8 in the human tubule hypoxia cell culture model. ( A ) RNAseq values of genes within rat LD block within the RPTEC TERT1 normoxic vs hypoxic conditions. Genes on the right are significant genes. ( B ) TPM values in each of the RNAseq groups for SEPTIN8 in the RPTEC TERT1 cells. ( C ) Expression of SEPTIN8 in single cell datasets (human and mouse). ( D ) Immunohistochemistry from the Human Protein Altas (modified from www.proteinatlas.org/ENSG00000164402-SEPT8/tissue/kidney ) for SEPTIN8 using HPA005665 antibody. Labels are added for tubules and glomerulus. ( E ) Immunofluorescence of SEPTIN8 (red) with acetyl-alpha tubulin, actin, or ZO-1 (green) as labeled. SEPTIN8 localizes with acetyl-alpha tubulin under shear stress with normoxic conditions. ( F ) Under hypoxic conditions, however, SEPTIN8 re-localizes near the actin filaments.

- Figure 6 SEPTIN8/ Sept8 expression increases under conditions of fibrosis or wounding. ( A ) Immunohistochemistry of SEPTIN8 in human biopsies. Results are shown from three separate biopsies with varying levels of tubulointerstitial injury ranging from none (biopsy 22) to moderate (biopsy 12) to severe (biopsy 4). The top panel provides representative low resolution (20X) image of the tubule/interstitial region. The bottom panel provides an independent representative high resolution image (40X) of a single glomerulus. ( B ) Interrogating mouse single-cell databases demonstrates very high levels of Sept8 in response to stimulus or wounding and ( C ) HS rats with high levels of UPE exhibit significantly increased levels of Sept8 relative to HS rats with low to moderate urinary protein levels. rt-qPCR was run in all HS rats that were selected for histological analysis as described in Fig. 1 . * p < 0.05 vs very low, + p < 0.0001 vs all groups.
