Figure 2. Effect of TGF-β1 on expression of neuronal-specific markers by RGC-5 cells.
Western blot analysis for: (A) Brn-3c, (B) NF-160 and (C) Thy1.2 and realtime-PCR for: (D) Thy1.2, (E) Tau and (F) PGP9.5. Brn-3c and NF-160 were not detected in undifferentiated RGC-5 but were expressed by differentiated RGC-5. Thy1.2 was present in undifferentiated RGC-5s and increased after differentiation. Differentiation increased expression of Thy1.2, Tau and PGP9.5. Addition of TGF-β1 to differentiated RGC-5 cells increased NF-160, but not Brn-3c or Thy1.2 protein and increased PGP9.5, but not (D) Thy1.2 or (E) Tau mRNA. N = 3; *p<0.05
