MYB and HIF1α crosstalk drives hypoxia-induced transcriptional reprogramming and adaptive signaling alterations in pancreatic cancerCancer letters · 2025
Summary (written by the submitters)
Pancreatic cancer is an aggressive malignancy, characterized by extensive desmoplasia and a hypoxic tumor microenvironment that contributes to therapy resistance. MYB, a proto-oncogene encoding a transcription factor, plays a crucial role in pancreatic tumor growth, metastasis, and desmoplasia. Recently, we also revealed a role of MYB in hypoxic survival of pancreatic cancer by promoting metabolic reprogramming through interaction with HIF1α, modulating its expression and influencing its binding to glycolytic gene promoters.

In this study, we examined the impact of hypoxia on the genome-wide occupancy of MYB by performing chromatin immunoprecipitation sequencing (ChIP-seq) analysis. We also used HIF1A knockout cells to investigate the role of HIF1α in altered genomic occupancy of MYB. In addition, we examined the genomic distribution of HIF1α in presence and absence of MYB and the impact of their crosstalk on transcriptional reprogramming and associated signaling alterations by RNA-seq and pathway analyses. Our findings show that hypoxia induces significant changes in MYB’s genomic distribution, partially dependent on HIF1α, and that MYB facilitates HIF1α binding to specific gene promoters. We also identify a subset of hypoxia-induced genes co-regulated by MYB and HIF1α, involved in oncogenic signaling pathways critical for hypoxic adaptation. These results highlight the reciprocal crosstalk between MYB and HIF1α, providing novel mechanistic insights into pancreatic cancer adaptation under hypoxia and suggesting MYB as a potential therapeutic target.

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 GSE292665_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1240653 and SRA study SRP572365. Searching any of these in the dataset finder brings you back here.
