Microarray analysis of 16 Cln3Δex7/8 brain tissue samples treated with vehicle or GalCer (four males and four females in each group) was performed using the GeneChip Mouse Genome 430 2.0 array platform from Affymetrix (Affymetrix Inc., CA, USA) representing over 45,000 probe sets) (Fig 1). Samples were prepared and microarrays processed using the GeneChip™ 3’ IVT PLUS Reagent Kit (Thermo Fisher Scientific, MA, USA) according to manufacturer instructions. Briefly, 100 ng of total RNA were labeled, fragmented, and then hybridized to arrays. After washing and staining using GeneChip Fluidics Station 450 (Thermo Fisher Scientific, MA, USA), arrays were scanned with the GeneChip Scanner 3000 7G (Thermo Fisher Scientific, MA, USA). Cell Intensity Data (CEL) files were generated with the Affymetrix GeneChip™ Command Console (AGCC) software version 3.2 (Thermo Fisher Scientific, MA, USA).

Microarray Analysis of Head and Neck SCC Transcriptome

Check if the same lab product or an alternative is used in the 5 most similar protocols
Microarray analysis was performed as follows. Total RNA was extracted by lysing the tissues with Isogen (Nippon Gene) following homogenization with a TissueLyser (Qiagen AB). Total RNA (500 ng) was used to generate biotin-labeled cRNA using a GeneChip® 3′ IVT PLUS Reagent kit (Thermo Fisher Scientific, Inc.). The biotin-labeled RNA was hybridized to Human Genome U-219 Array Strips (Thermo Fisher Scientific, Inc.). After washing and staining the strips, the signal was developed and scanned using GeneAtlas (Thermo Fisher Scientific, Inc.). Data analysis was conducted using GeneSpring GX 14.9.1 (Agilent Technologies GmbH). The robust multichip average method was used with background correction and normalization. Fold change analysis was performed to identify genes with >3-fold differences, using a moderated t-test (P<0.05) with Benjamini-Hochberg multiple correction. Gene expressions of KRT8, ABCC3, GCLC, RYBP, TMEM97, SLC1A3, IRS2, KYNU, CSAG2, CDA and CCL21 in head and neck SCCs (528 cases) from the cancer genome atlas were analyzed by OncoPrint from cBioPortal. Microarray data have been deposited in the Gene Expression Omnibus (GEO; experiment. no. GSE153918) database using minimum information about microarray experiment guidelines. The algorithm of the clustering method for the microarray data is shown in Fig. S1.

Transcriptome Profiling of Cell Types

Check if the same lab product or an alternative is used in the 5 most similar protocols
Quality and quantity of the 60 nucleic acid samples were established using the Agilent Bioanalyzer RNA Nano kit and the Nanodrop 1000, respectively. GeneChip 3′ IVT PLUS Reagent Kit (Thermo Scientific) provided sufficient amplified double-stranded cDNA for each holoclone, meroclone, or paraclone total RNA sample, letting to in vitro transcribe it to labeled cRNA, that could be fragmented and therefore hybridized onto single GeneChip™ Human Genome U133 Plus 2.0 Array (ThermoScientific), following the manufacturer’s indications. To avoid batch effect among samples, i.e. no technical sources of variation added to the samples during handling, samples were randomized during RNA isolation, sample preparation, and hybridization/scanning working sessions. All samples were processed with the same reagents lot number, when available. Sample and hybridization quality controls were carried out with Transcriptome Analysis Console (TAC, ThermoScientific) to verify complete and unbiased coverage of the transcriptome.

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.
