Levels of bornaviral N (nucleoprotein) segment RNA were measured by qRT-PCR of BD, BD+WIN, BD+HU rats in each of 3 regions: PFC, striatum, and hippocampus (Experiment 3). Previous study has shown RT-PCR quantification correlates with measurements of viral burden by focus forming unit assays ( Solbrig et al., 2002). The hippocampus was added because it is a structure reliably infected early in disease in this model. Brain regions were dissected as described (Solbrig et al., 1994, Solbrig et al., 2002 and Solbrig et al., 2006) and total RNA was extracted using

RNEasy Plus Universal Extraction System (Qiagen, Toronto, ON) according to manufacturer’s instructions. Frozen tissues were weighed, homogenized in 150 μl Qiazol Lysis Agent Anticancer Compound Library with sterile disposable RNase/DNase-free pestles, Carfilzomib nmr brought to volume with Qiazol Lysis Agent, further disrupted by trituration. Viral RNA was eluted from silica columns

with 40μl RNase free water containing 0.5 U/μl RNase Out (Invitrogen/Life Technologies, Burlington, ON), and placed in 5 μl aliquots. Quantitative RT-PCR was conducted with a LightCycler 480 (Roche, Laval, QC) using the QuantiFast Pathogen RT-PCR+IC system (Qiagen) with primer set p40bobe-286R(GCA CCC CTC CGT GAA CAA)/p40bobe-187F(CAG TCA CGG CGC GAT ATG T), per manufacturer’s instructions. Reverse transcription was conducted at 50 °C, followed by 45 cycles annealing/elongation at 60 °C and melting at 95 °C. Probe p40bobe-247T (6Fam-ATC CCA GGA CTG CAC GCT GCG TT-BBQ) (TIBMolbiol, Adelphia, NJ) was used to detect amplified product (Solbrig et al., 2002). Serial log dilutions (10−2–10−8) of a known positive stock extract were included in each assay for quantification of vRNA. Absolute quantification with 2nd derivative maximum was Grape seed extract established using the LightCycler 480 programming, and copies vRNA/μg tissue were determined.

Numeric data are represented as mean+SEM and are considered significant if p<0.05. Statistical analysis was performed using Student's t tests (for comparisons of two groups) or one-way ANOVA followed by Tukey's post hoc test (for more than 2 groups). To compare co-expression of various markers in BrdU+ cells, the percentage or proportional data for differences in treatment groups, set in 2×2 tables, were analyzed by Chi square test with Yate's correction. All analyses were carried out with the GraphPad Software (San Diego, CA, USA).
