Fig. 6: Effect of p75NTR stimulation on lipid-associated genes in Huh7 cells.

Huh7 cells were stimulated with 100 ng/ml NGF or 20 ng/ml pro-NGF for 48 h, and the expression of lipid-associated genes was analyzed by qPCR. Primers are shown in Table 2. Results were normalized to GAPDH and controls set to 1. Values are mean ± SD, n = 3-4. ***p < 0.001, **p < 0.01, or *p < 0.05 for treated cells vs. corresponding controls. a Hydroxy-delta-5 steroid dehydrogenase (HSD3B1) and b in the presence of 1 μM inhibitor, SB203580 (SB). c Acyl CoA transferase 2 (ACOT2) and d in the presence of 1 μM SB. e Serine palmitoyl transferase (SPTSSB). f Cluster of differentiation (CD36). g Fibroblast growth factor-21 (FGF21). h–j Immunoblots (h) with quantification (i) showed an increase in caspase-2 (CASP2) expression level by NGF and pro-NGF. j qPCR analysis for pro-NGF demonstrated an increase in caspase-2 expression. Values are mean ± SD, n = 3. **p < 0.01 or *p < 0.05 for treated cells vs. controls
