Article Title: Inactivation of Cys 674 in SERCA2 increases BP by inducing endoplasmic reticulum stress and soluble epoxide hydrolase
doi: 10.1111/bph.14937
Figure Lengend Snippet: The sustained induction of ER stress by inactivation of SERCA2 C674 accounts for the elevated BP. (a) Representative Western blots of ER stress markers from the renal cortex and quantification of band intensities in graph. Mean ± SEM, unpaired Student's t test, * P < .05, significantly different as indicated, n = 5. (b) Representative Western blots of ER stress markers from primary RPT cells and quantification of band intensities in graph. Mean ± SEM, unpaired Student's t test, * P < .05, significantly different as indicated, p‐PERK, n = 7; BIP, n = 6; ATF6, n = 5; CHOP, n = 6. (c) Na+/K+‐ATPase activity in primary SKI RPT cells treated with 4‐PBA. Mean ± SEM, unpaired Student's t test, * P < .05, significantly different as indicated, n = 5. (d) The effects of 4‐PBA on BP. Mean ± SEM, two‐way ANOVA, * P < .05, significantly different as indicated,; # P < .05, significantly different as indicated, n = 5. (e) The effects of 4‐PBA on SKI urine volume and urine sodium secretion. Mean ± SEM, unpaired Student's t test, * P < .05, significantly different as indicated, n = 5
Article Snippet: Primary antibodies against SERCA2 C674‐SO 3 H (Ying et al., 2008 ; C674‐SO 3 H antibody was a custom polyclonal antibody from Bethyl Laboratories, Inc.), https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=2970 ( https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=2970 ; Santa Cruz, Cat# sc‐87099, RRID:AB_2293440), or https://www.guidetopharmacology.org/GRAC/ObjectDisplayForward?objectId=214 (Abcam, Cat# ab81296, RRID:AB_2814742) were incubated overnight at 4°C according to the staining procedure of HRP‐DAB kit (CWBIO, Cat# CW0125M).
