Real time quantitative RT PCR validation of mRNA and miRNA The data for mRNA and miRNA were selectively corro borated with real time PCR to ascertain their expression trends. For mRNA, 5ng total RNA was reverse tran scribed using oligo d and Superscript III followed by Inhibitors,Modulators,Libraries RNase H treatment, per manufacturers instructions. PCR primers were designed for all the 11 genes selected on the basis of the microarray data as well as for the control genes, using the online software Primer 3. All primer pairs were optimized to ensure the specific amplification and the absence of any primer dimer. Quantitative PCR standard curves were set up for all. The cDNA was then subjected to real time quantitative PCR with defined pri mers and SYBR Green using Mx3000p Stratagene real time thermal cycler.

The data were analysed using the MxPro QPCR software version 4. 0. 1. For miRNA, expression levels of six DE miRNAs were validated by quantitative real time RT PCR using the Qiagen miScript PCR system according to the manufactures protocol. Hs RNU6B 3 was used as the endogenous control to normalize the data. All the experiements Inhibitors,Modulators,Libraries were performed in duplicate and relative expression levels of these mRNAs miRNAs were determined by the 2 Ct method. The data then were further analysed by Student t test to check the statistical significance between HAD and HIV non dementia patients brains. Transfection of microRNA mimic SH SY5Y cultures were maintained as confluent mono layers at 37 C with 5% CO2 and 90% humidity in SH SY5Y media foetal calf serum, 20 mM HEPES, 2 mM L glutamine.

For differ Inhibitors,Modulators,Libraries entiation cells were seeded at 4 �� 104 cells cm2 and trea ted with all trans retinoic acid media for five days, followed by treatment in brain derived neurotrophic factor media for three days. Cells were then harvested and nucleofected using Amaxa Nucleofector Kit V according to manufacturers instructions. Each nucleofection contained 4 �� 106 cells and 0. 1 nmol miR 137 or mirVanaTM miRNA mimic Negative Control 1, with experiments performed in duplicate. Nucleofected cells were seeded at 5 �� 104 cm2 in BDNF media Inhibitors,Modulators,Libraries and grown for 24 hrs before being harvested with TRIzol and RNA isolated as described. Functional validation of proteins using western blot Western blot was employed to validate part of the microarray data.

4 HAD patients and 4 HIV non dementia patients brain samples were used for valid ation of the microarray study Dacomitinib by western blot analysis. Total cellular proteins were extracted as described be fore. 40 ug proteins were separated by 12% SDS polyacrylamide gels first and then transferred to PVDF membranes or nitrocellulose mem branes using Bio Rad apparatus. Membranes were blocked in 5% skim milk powder or 5% BSA in tris buffered saline for 1 hour at room temperature. Following that, they were incubated for 2 hours at room temperature with each of the fol lowing primary antibodies, Rabbit anti MEK2 and JNK1. Mou
