doi: 10.1016/j.neulet.2018.07.015
Figure Lengend Snippet: DIV8 primary rat cortical neurons were treated with vehicle (Control, n = 4) or 1 μM of SKF38393 (D1 dopamine receptor agonist, n = 4) for 1.5 h. (A) qPCR analysis revealed a small decrease in Hnrnph1 mRNA (top left) [Exon 4–5: unpaired Student’s t-test, t6 = 2.866, *p = 0.03; Exon13–15: unpaired Student’s t-test, t6 = 3.367, *p=0.02] or Hnrnph2 mRNA (top right) [unpaired Student’s t-test, t6 = 2.432, p = 0.051]. (B) Immunoblot analysis of fractionated samples indicated no significant change in hnRNP H protein levels in the nucleus (Nu) or cytoplasm (Cy), as detected by either C-domain (left) or N-domain (right) antibodies. Two-way ANOVA with Cellular Compartment and Treatment as factors revealed a significant effect of Cellular Compartment [C-domain: F(1,12) = 51.45, p = 1.13 × 10−5; N-domain: F(1,12) = 123.52, p = 1.13 × 10−7], no significant effect of Treatment [C-domain: F(1,12) = 1.06, p = 0.32; N-domain: F(1,12) = 4.11, p = 0.07], and no interaction [C-domain: F(1,12) = 0.26, p = 0.62; N-domain: F(1,12) = 2.66, p = 0.13]. Successful nuclear and cytoplasmic fractionation was confirmed by CREB and HSP90. For either C- and N-domain immunoblot study: Control: n = 4, 1 μM SKF38393: n = 4. Black bar = Control; white bar = SKF treatment.
Article Snippet: Primary rat cortical neuron culture and neuronal treatment Primary rat cortical neurons were dissected from neocortex of E18 Sprague-Dawley embryos (Charles River Laboratories, Wilmington, MA, USA) and grown in media as described [ 19 ].
