Figure Lengend Snippet: Fatty acid treatment induces a proinflammatory phenotype in astrocytes. Relative luminescence produced by firefly luciferase expressed under the control of an NF‐κB‐driven promoter after 24 h of treatment with (A) oleic acid (OA, 50 and 100 μM) and (B) linoleic acid (LA, 50 and 100 μM), in nontransgenic neonatal spinal cord astrocytes cultures. Control cultures were treated with BSA (used as a carrier for FAs). Relative firefly luciferase luminescence was corrected by the amount of Renilla luciferase activity controlled by a constitutive promoter and expressed as a percentage of vehicle (BSA)‐treated cultures ( n = 3, mean ± SD). (C–F) Representative images depicting immunostaining against NF‐κB‐p65 (red) and GFAP (green) in neonatal spinal cord astrocytes 4 h after treatment with (C) OA (50 μM) or (E) LA (50 μM). Nuclei were counterstained with DAPI (blue). Scale bar: 25 μm. Quantification of NF‐κB‐p65‐positive nuclei in neonatal spinal cord astrocytes 4 h after treatment with (D) OA (50 μM) or (F) LA (50 μM).

Nuclei were counterstained with DAPI (blue). Scale bar: 50 μm. (C) Quantification of LD in spinal cord astrocytes treated as indicated above. LD numbers were normalized by the number of nuclei analyzed ( n = 4, mean ± SD).

(E and F) Motor neuron survival determined 72 h after being plated on top of astrocytes treated as indicated above ( n = 4, mean ± SD).

Neonatal spinal cord astrocytes were treated with vehicle (BSA) or fatty acids for 24 h, followed by treatment with vehicle (DMSO) or GSK2837808A (2.5 μM, LDHi) and/or Etomoxir (10 μM) for 24 h.

Figure Lengend Snippet: Lactate dehydrogenase gene ablation reverts the effect of fatty acid treatment in neonatal spinal cord astrocytes. (A) Primary confluent spinal cord astrocyte cultures obtained from neonatal Ldha flox/flox mice were transduced with an adenovirus expressing Cre recombinase (CRE) or an empty ORF (NULL). Seventy‐two hours later lactate dehydrogenase A (LDHA) expression was analyzed by Western blot. (B) LDHA expression was quantified, normalized by actin levels, and expressed as a percentage of NULL‐treated cultures ( n = 3, mean ± SD). (C) Ldha flox/flox spinal cord astrocyte cultures treated as above were subsequently exposed to oleic acid (OA, 50 μM) for 24 h. Representative images of LD staining (LipidGreen2). Nuclei were counterstained with DAPI (blue). Scale bar: 50 μm. (D) Quantification of LD in spinal cord astrocytes treated as indicated in (C). LD numbers were normalized by the number of nuclei analyzed ( n = 3, mean ± SD). (E) Relative luminescence produced by firefly luciferase expressed under an NF‐κB‐driven promoter in cultures treated as indicated in (C). Relative firefly luciferase luminescence was corrected by the amount of Renilla luciferase activity controlled by a constitutive promoter and expressed as percentage of control cultures (NULL/BSA) ( n = 4, mean ± SD). (F) Motor neuron survival determined 72 h after being plated on top of Ldha flox/flox spinal astrocytes treated as indicated in (C) ( n = 4, mean ± SD). **** p < 0.0001, ** p < 0.01, *p < 0.05.
