Fig 7 Spastin influences transcription and location of HSP-related proteins to control ER/LD dynamics.

(A) Quantification of REEP1, Atlastin1, Spartin and Seipin transcript by qPCR in 8 months old zebrafish brain. n = 4 animals per group. (B) Quantification of REEP1, Atlastin1, Spartin and Seipin transcript by qPCR in 8 months old zebrafish skeletal muscle. n = 4 animals per group. (C-D) Confocal microscopy images of HeLa cells overexpressing human Seipin with Spastin M1 isoforms (wild-type and mutants) treated with oleic acid (OA) for 18h. Cherry-tagged Spastin appears in red, Seipin in green, LDs (Bodipy) in magenta and nucleus (Hoechst) in blue. (E) Percentage of cells exhibiting tubular ER along MTs. (F-G) Confocal microscopy images of HeLa cells overexpressing human REEP1 with Spastin M1 isoforms in basal conditions (F) or after 18h administration of OA (G). Cherry-tagged Spastin appears in red, REEP1 in green, LDs (Bodipy) in magenta and nucleus (Hoechst) in blue. Bars are mean ± SEM, ^#P = 0.08, *P < 0.05, **P < 0.01, ***P<0.001 (unpaired t‐test).
