Summary (written by the submitters)
Cervical cancer is the fourth most common cancer worldwide in females. This occurs primarily due to the infection of high-risk human papillomavirus (HPV) although in advanced stages it requires support from host cellular factors. BRN3A is one such host cellular factor that upregulates tumorigenic high-risk HPV expression. The expression of BRN3A in cervical cancer remains high where it enhances tumorigenicity.

The effect of BRN3A on HPV-mediated cervical cancer and the underlying mechanism remains obscure. Thus, we have investigated the overall effect of BRN3A on genes associated with cancer-related different biological processes. In approach, we have altered the expression of BRN3A through overexpression and knockdown in cervical cancer cells following transcriptome profiling through next-generation RNA-sequencing. This study revealed a substantial change in the expression of several genes associated with cancer-promoting biological processes including viral processes, immune response, cell-death, cell-proliferation, and different signaling pathways, etc. Additionally, promoter analysis through in silico mode revealed that a total of 32.7% of genes possess BRN3A binding sites at their promoters. Physical interaction of BRN3A with IFITM1, OAS3, ISG15, BCL2L1, and HSP90AB1 genes was also confirmed. Thus, the present study identified molecular targets of BRN3A and provided new insight into the pathogenesis of cervical cancer. According to our knowledge, this is the first report on the effect on eukaryotic transcriptomes after over-expression and knocking down BRN3A.

Download · which file do I need?

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 GSE255288_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 PRJNA1074375 and SRA study SRP488760. Searching any of these in the dataset finder brings you back here.
