What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.

Samples
20 samples: 5 × KD vs 5 × KD-NC vs 5 × OE vs 5 × OE-NCGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Summary (written by the submitters)
Objective: This study aims to investigate the impact of differentially expressed tryptophan 2,3-dioxygenase (TDO2) on hepatocellular carcinoma (HCC) growth and its role in regulating ADCY5 and PRKAR2B expression in cells and tissues. Methods: Serum amino acid profiles in patients with HCC were analyzed via metabolomics. Lentiviral transfection was used to knock down and overexpress TDO2 in cells, with corresponding subcutaneous tumor models established in nude mice.

A rat model of primary hepatocellular carcinoma was generated through intraperitoneal injection of N-nitrosodiethylamine (DEN). Cellular responses were assessed using CCK8, Annexin V-PE/7ADD double staining, and scratch assays. Transcriptome sequencing was performed to analyze genetic alterations in subcutaneous tumor tissues, while RT-qPCR and Western blotting were employed to quantify mRNA and protein levels. Results: TDO2 knockdown inhibited hepatocellular carcinoma cell proliferation and migration, while promoting apoptosis. Conversely, TDO2 overexpression enhanced cell proliferation and migration. Moreover, ADCY5 overexpression reverses the tumor-suppressive effects elicited by TDO2 knockdown. Transcriptome sequencing revealed an association between TDO2 and the downstream genes ADCY5 and PRKAR2B. In both cellular and animal models, mRNA levels of ADCY5 and PRKAR2B were positively correlated with TDO2 expression. Conclusion: TDO2 may facilitate HCC growth and metastasis by activating ADCY5 expression and its downstream target PRKAR2B.

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE309614_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1336613 and SRA study SRP629951. Searching any of these in the dataset finder brings you back here.

Study design
5 × KD vs 5 × KD-NC vs 5 × OE vs 5 × OE-NC

Supports a between-group comparison across 20 samples.

How we read this: 4 replicated groups read from 20 sample titles; they account for 20 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
