HIF-2-Dependent Regulation of PTHrP and Paraneoplastic Hypercalcemia in Aggressive Clear-Cell Renal Cell CarcinomaCancer discovery · 2025
Summary (written by the submitters)
Hypercalcemia (HC) in renal cell carcinoma (RCC) patients is associated with reduced survival. HC often involves PTHrP. PTHrP is induced by hypoxia, but whether HIF-2 plays a role in HC is unknown. Here we show that HC is reproduced by transplanting patient tumors (tumorgrafts, TG) in mice resulting in functional deterioration, weight loss, calcium deposition and organ damage.

Treatment with PT2399, a specific HIF-2 inhibitor, rapidly normalized calcium levels, downregulated PTHrP and reduced HIF-2 binding to the PTHLH promoter. Interestingly, while the PTHLH locus was generally more accessible in TG(HC), PT2399 did not grossly affect chromatin accessibility, which was consistent with genome-wide studies where promoter accessibility was only reduced in a minority of PT2399-downregulated genes. As in TGs, paraneoplastic HC in humans was associated with clear cell histology and sarcomatoid/rhabdoid differentiation. Interestingly, HC (and PTHrP) was swiftly corrected by the related PT2977/belzutifan drug in a prospective patient with sarcomatoid ccRCC. Our data supports the evaluation of HIF-2 antagonists for ccRCC patients with humoral hypercalcemia of malignancy, which may serve as a predictive biomarker of response (along with PTHrP reduction).

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 GSE308450_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 PRJNA1330617 and SRA study SRP621808. Searching any of these in the dataset finder brings you back here.

Study design
35 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 35 sample titles: 35 distinct titles with little repetition. 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.
