Then, using HBSS solution that NaCl was substituted by LiCl (10 mM), we found that compared with the control group, LiCl increased the levels of [Ca2+]i, and KB-R7943 reversed calcium influx (Fig. 4b), supporting the assumption that NCX1 had the function of transporting Ca2+ in MM cells. Here, SLC8A1 is linked to Miyoshi myopathy.
