Figure Lengend Snippet: A , Effect on migration. ATP increased Sca‐1 + cell migration, which was significantly inhibited by the IK Ca channel blocker TRAM34 ( a ). MCP‐1 also enhanced migration, and TRAM34 similarly suppressed this increase ( b ). (Statistical significance was confirmed by HC3‐robust interaction model with 6 biological replicates.) B , The ATP‐enhanced migration of Sca‐1 + cells was significantly abolished by IK Ca channel inhibition with shKCNN4 ( P =0.0360, HC3‐robust interaction model, n=5). C , The proliferation of Sca‐1 + cells induced by ATP ( a , b ) and PDGF‐BB ( c ) was significantly suppressed by inhibition of IK Ca channels with TRAM34 or shKCNN4 ( P values are indicated on the graph; HC3‐robust interaction model, n=5). ATP indicates adenosine triphosphate; CON, control; HC3, heteroskedasticity‐consistent robust SE; IK Ca , intermediate conductance calcium‐activated potassium channel; MCP‐1, monocyte chemoattractant protein‐1; PDGF‐BB, platelet‐derived growth factor‐BB; Sca‐1 + , stem cell antigen‐1 positive; shKCNN4, a short hairpin RNA construct specifically designed to target and silence the expression of the KCNN4 gene; and TRAM34, 1‐ [(2‐chlorophenyl) diphenylmethyl]‐1h‐pyrazole.
Article Snippet: They were then blocked with BSA and incubated overnight with an anti‐ KCNN4 receptor (extracellular) antibody (1:200, Alomone, Jerusalem, Israel, #APR‐102).
