Total cellular RNA was extracted from hBMMSCs of P7 and P65 using the TRIzol reagent as instructed by the manufacturer (Invitrogen Life Technologies). RNA (1 μg; RIN value >6) was used for generation of second-strand cDNA, and cRNA was amplified with the Oligo dT primer, then biotinylated and fragmented with One-Cycle Target Labeling and control reagents (Affymetrix, Inc., Santa Clara, CA, USA), followed by hybridization to U133 Plus 2.0 array overnight (17 h) according to the manufacturer’s instructions. Finally, the hybridized DNA microarray was fluorescence stained with GeneChipFluidics Station 450 (Affymetrics) and scanned with a GeneChip Scanner 3000 (Affymetrics). GCOS1.2 Affymetrix GeneChip Command Console (TGCC) was employed to extract the data in the microarray followed by analysis with the Robust Multi-Array Average (RMA) method. The relative gene expression was calculated. A difference of >2 or <0.5-fold and reliability (P<0.05) was considered to indicate significant differences in gene expression.

RNA Pooling and Microarray Analysis in Mouse Model

Check if the same lab product or an alternative is used in the 5 most similar protocols
Equal quantities of RNA from mice of the same genotype and time point were pooled for microarray assays. For sham-infected mice, equal quantities of RNA from mice of the same genotype and all three time points were pooled as control uninfected mice. Samples were labeled for GeneChip analysis using the One-Cycle Target Labeling and Control Reagents (Affymetrix). The gene expression array used was the Affymetrix Mouse Gene 1.0 ST array.

Transcriptomic Analysis of Theanine Ingestion in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
The mice were housed confrontationally for three days after single housing for one month. Group-housed mice were kept in a group of six for one month. Mice were anesthetized with isoflurane and blood was removed from the jugular vein. The hippocampus was removed and frozen immediately. Total RNA was extracted from the hippocampus using an RNeasy Mini Kit (74104, Qiagen, Valencia, CA, USA). Total RNA was processed to synthesize biotinylated cRNA using One-Cycle Target Labeling and Control Reagents (Affymetrix, Santa Clara, CA, USA) and then hybridized to a Total RNA Mouse Gene 1.0 ST Array (Affymetrix), with three biological repeats per group. Raw data were parametrically normalized [45 (link)] by using the SuperNORM data service (Skylight Biotech Inc., Akita, Japan). The significance of theanine ingestion was statistically tested by two-way ANOVA [46 (link)] at p < 0.001.
To compare the effects of theanine ingestion in the control under group or confrontational housing, we performed principal component analysis (PCA) [47 (link)] on ANOVA-positive genes [48 (link)]. To reduce the effects of individual variability among samples, the axes of PCA were estimated on a matrix of each group’s sample means and applied to all data, which were centered using the sample means of control mice under group housing.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
