One ug of total RNA was reverse-transcribed into cDNA using RT2 First Strand Kit (Qiagen, Valencia, CA, USA). Custom RT2 Profiler PCR array plates including controls for human genomic DNA contamination, reverse transcription and PCR efficacy (SABiosciences, Qiagen) were used for RQ-PCR reactions performed using RT2 SYBR Green ROX qPCR Mastermix (SABiosciences) on an ABI 7900 thermal cycler (Applied Biosystems, Foster City, CA, USA) as described previously47 .

Postmortem brain tissue was obtained from the eight old DHEA-supplemented animals, as described above. Total RNA was extracted from the hippocampi (HPC) and dorsolateral prefrontal cortices (PFC) using the RNeasy Mini Kit (Qiagen, Valencia, CA, USA), and converted to cDNA using the RT2 First Strand Kit (SABiosciences, Qiagen, Valencia, CA, USA). The samples were then run on custom RT2 Profiler PCR Array plates (SABiosciences) in accordance with the kit instructions. Genes selected for inclusion on this plate were chosen for their involvement in either steroidogenesis (i.e., steroidogenic enzymes or transport proteins such as steroidogenic acute regulatory protein [StAR]) or steroid responses (i.e., steroid receptors and intracellular signaling proteins involved in the estrogen response). All genes were normalized against the arithmetic mean expression value of the three housekeeping genes, ALG9, GAPDH, and RPL13A.

MO3.13 cells seeded in T-75 flasks were treated with either medium or B. burgdorferi (10:1 MOI) for 6 h, after which RNA was extracted using RNeasy® mini kit (Qiagen, Germantown, MD) according to the manufacturer’s instructions. NanoDrop® ND-1000 (NanoDrop Technologies Inc., Wilmington, DE) was used to quantify RNA concentration, and 1 μg of RNA was used for cDNA synthesis (RT2 First strand kit), which was aliquoted on RT2 Profiler PCR array plates (human TLR signaling pathway) using RT2 SYBR® Green ROX qPCR mastermix (Qiagen, Germantown, MD). The real time PCR reactions were run on Applied Biosystems 7900HT cycler and data captured using SDS 2.4 software. All protocols were carried out according to the manufacturer’s handbook. The resulting raw data were analyzed on SABiosciences web-based software (www.SABiosciences.com/pcrarraydataanalysis.php) to determine the fold change in gene expression in cells exposed to B. burgdorferi over medium control. Fold changes (upregulation) over 1.2 fold were considered for further review. Ct values > 34 were considered as too low an expression and not included for analysis.

RNA (input of total RNA: 1.0 µg per reaction) was reverse transcribed using the RT2 First-Strand kit (Qiagen). Subsequently, profiler array-based quantitative PCR analysis was performed, following the instructions of the supplier, using the RT2 SYBR Green PCR Mastermix (Qiagen) and primer pre-coated RT2 Profiler PCR array plates (Qiagen) encompassing 84 pathway-focused genes per plate. Two different human-specific profiler PCR arrays were screened: pathways related to EMT signaling and the TGF-β/bone morphogenic protein (BMP), each on two independent biological replicates.

Prior to cDNA synthesis, RNA was adjusted to a final concentration of 1 μg RNA per μL of RNAse free water (Qiagen, Manchester, UK). Each sample was reverse transcribed with Random Primers (Promega, UK) and Bioscript Reverse Transcriptase (Bioline, Nottingham, UK). cDNA was plated into the 96 well RT2 Profiler PCR array plates (human wound healing gene panel, Qiagen) with Takyon SYBR mastermix (Eurogentec, Hampshire, UK). Plates were run on a CFX Connect thermal cycler using CFX Manager Software (Biorad, Hertfordshire, UK). R v.3.6.1 was used for t test comparisons (tNPWT vs sNPWT), while clustering was based on Euclidian distance and Ward D2's method using the R packages “RColorBrewer” and 'gplots'.21

Investigating p53 Regulation of pH Homeostasis

Check if the same lab product or an alternative is used in the 5 most similar protocols
MDA-MB-157 cells stably expressing either p53-WT or p53-R273H were plated in 10-cm dishes and grown to ~50% confluency before beginning experimental modulation of pHi. To raise or lower pHi, medium was supplemented with 5 mM NH4Cl or 10 µM EIPA, respectively, for 48 hours. To induce a p53 response, 10 µM etoposide was added for the final 12 hours. Cells were harvested, and total RNA was extracted using the RNeasy Mini Kit (Qiagen). For each condition, 0.5 µg total RNA was used. Synthesis of complementary DNA was performed using the RT2 First Strand Synthesis Kit (Qiagen), and the 96-well RT2 Profiler PCR Array plates (Qiagen, PAHS-027ZA) were prepared according to the manufacturer’s instructions. The assay was performed on three independent preparations of cells for each condition. The RT2 PCR Array data sets were processed using the SAB PCR Array Data Analysis Web portal (http://pcrdataanalysis.sabiosciences.com/pcr/arrayanalysis.php), with a boundary cutoff of threefold increase in expression.

Gene Expression Analysis in DENV-infected HFDPCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNA was extracted from HFDPCs by using Trizol reagent (Thermo Fisher Scientific) as instructed in the protocol. Total RNA (1,000 ng) from each sample underwent cDNA synthesis by using the RT2 First Strand Kit (Qiagen, Valencia, CA). The resulting cDNA was mixed with H2O plus SYBR green dye, and then dispensed into a 96-well RT2 Profiler PCR array plate as described (Qiagen). DNA amplification was carried out using the Applied Biosystems StepONE Plus Real-Time PCR system (Thermo Fisher Scientific). The fold-change in gene expression in DENV-infected HFDPCs was relative to that of the untreated control. We considered a fold-change threshold of at least two-fold upregulation or downregulation.
The specific gene expression was also confirmed by RT-qPCR. cDNA was synthesized from 500 ng total RNA using Superscript III Reverse Transcriptase (Invitrogen). qPCR amplification was carried out with 3 ng of cDNA in 10 μl SYBR Green using the Applied Biosystems StepONE Plus Real-Time PCR system (Thermo Fisher Scientific). Transcript levels were normalized to that of glyceraldehyde 3-phosphate dehydrogenase (GAPDH). The primer sequences for gene detection are provided in Table S1.

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.
