Primer sequences were designed using Beacon Designer 8™ (Premier Biosoft, Palo Alto, CA, USA) for TTR (Forward: 5’-ATTCTTGGCAGGATGGCTTC-3’, Reverse: 5’-CAGAGGACACTTGGATTCACC-3’); Ttr (Forward: 5’-AGCCCTTTGCCTCTGGGAAGAC-3’, Reverse: 5’-TGCGATGGTGTAGTGGCGATGG-3’); glyceraldehyde 3-phosphate dehydrogenase (Gapdh) (Forward: 5’-GCCTTCCGTGTTCCTACC-3’, Reverse: 5’-AGAGTGGGAGTTGCTGTTG-3’) and 18S (Forward: 5’-AAATCAGTTATGGTTCCTTTGGTC-3’, Reverse: 5’-GCTCTAGAATTACCACAGTTATCCAA-3’). Differential expression was determined by the 2^-∆∆CT method.

Samples were directly transferred from −80 to a 65°C water bath for 15 min to lyse cells and mixed with 50 μl chloroform for 5 min at room temperature. The aqueous phase was recovered after centrifugation for 15 min at 13,000 g, 4°C. Total RNA was purified using RNeasy Mini Kit (Qiagen) with on-column DNase I treatment following the manufacturer's instructions, and eluted in 15 μl RNase-free water. RNA concentration was quantified on a Nanodrop ND-1000 spectrophotometer (Nanodrop Technologies, Inc.). Concentrations and ratios A260/280 and A260/230 are given in Supplementary Table 1. RNA integrity was confirmed by 0.8% agarose gel electrophoresis. The absence of genomic DNA was confirmed by PCR on purified RNA. The cDNAs were synthesized from 10 μg total RNA using the Superscript Double Stranded cDNA kit (Invitrogen), purified by phenol:chloroform:isoamylic alcohol extraction (v/v, 25:24:1), recovered by ethanol precipitation and resuspended in 15 μl nuclease-free water. The cDNA quality was confirmed on a Bioanalyzer (Agilent) using the RNA 6000 Nano kit (Supplementary Figure 1).

Transcriptome Analysis of Gut Tissue Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Gut tissue samples from the CTR and treatment groups (4 replicates) were collected for total RNA extraction using the TRIzol reagent (Invitrogen, Thermo Fisher Scientific, USA). Genomic DNA was removed using DNases I (Takara, Japan) and the RNA quality and integrity were measured using the ND-2000 NanoDrop (Thermo Fisher Scientific, USA) and agarose gel electrophoresis (1%). Total RNA (1 μg) was used for the construction of transcriptome libraries using the TruSeqTM RNA kit (Illumina, CA, USA). The mRNA was isolated with oligo (dT) beads according to the polyA selection method. Double-stranded cDNA was synthesized using the SuperScript double-stranded cDNA kit (Invitrogen, Thermo Fisher Scientific, USA) and was subjected to end repair. Phosphorylation, and ‘A’ base addition. Paired-end RNA-Seq library (2 × 150 bp) was sequenced with Illumina NovaSeq 6000 (CA, USA). Furthermore, the reads quality CTR, transcript assembling, expression analysis, functional annotation, identification of differentially expressed genes, and function enrichments were performed as previously described [35] , [36] (link).

Transcriptional analysis was performed on genes involved in EPS biosynthesis in S. thermophilus IMAU20561 grown for 5 h and 10 h in M17 medium containing different nitrogen sources, such as either soy peptone, tryptone, casein peptone as the sole sources or the complex nitrogen source typical of the M17 medium. The construction of the transcriptome library was done by the Shanghai Meiji Biological Analysis and Testing Co., Ltd. (Meiji, Shanghai) with the TruSeqTM RNA sample preparation Kit (Illumina, San Diego, CA). The mRNA was fragmented using metal ions and double-stranded cDNA was reverse transcribed with random primers using the SuperScript double-stranded cDNA kit (Invitrogen, CA). The second cDNA strand was synthesized, with dUTP instead of deoxythymidine triphosphate (dTTP), cDNA ends were patched with End Repair Mix and phosphorylated at the 5′ end and adenylated at the 3′ end. The cDNA library-enriched and the PCR were amplified using Phusion DNA polymerase (NEB). RNA-seq sequencing was done using Illumina HiSeq X Ten (2 × 150 bp).

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.
