Expression of TRPM7 dominant-negative (TRPM7-DN) suppresses differentiation by causing cell death. (A) Representative traces show the current-voltage relationship in HEK-293 cells with expression of wild-type TRPM7 alone or with coexpression of wild-type TRPM7 and the TRPM7-E1047K pore mutant (TRPM7-DN). (B) Co-expression of TRPM7-DN with wild-type TRPM7 in HEK-293 cells suppressed TRPM7 current densities at 120 mV and +100 mV. (C) Representative phase-contrast images of SH-SY5Y cells treated with retinoic acid (RA), at 4 and 6 days after plating. Shown are non-transduced (NT) cells, cells transduced with LacZ for 2 and 4 days, and cells transduced with TRPM7-DN for 2 and 4 days. Scale bar=200 μm. (D) Cell viability of non-transduced (NT), LacZ expressing, and TRPM7-DN expressing SH-SY5Y cells treated with RA 6 days after plating and 3 days post-transduction. Viability of TRPM7-DN transduced and NT cells was significantly different (Student′s t-test, p=0.006). Viability was expressed as percent of non-transduced (% NT) cells. |
