Abstract

Regucalcin (RGN), also reported as senescence marker protein-30 (SMP30), plays a role in Ca2+ homeostasis by modulating a number of Ca2+-dependent proteins. RGN also plays a cyto-protective role and its decrease is linked to age-related diseases and cell death. This study shows that RGN reduces agonist (histamine)-induced Ca2+ transients in RGN(+) transfected COS-7 cells (RGN(+)) and also increases their Ca2+ storage capacity. These observations are explained by RGN(+) cells having increased mRNA and protein expression levels of sarco/endoplasmic reticulum Ca2+-ATPase (SERCA). Therefore down-regulation of RGN expression may contribute to characteristics of age-dependent Ca2+ homeostasis dis-regulation, by decreasing SERCA levels.
