CDK4/6 inhibition induces a senescence-associated secretory phenotype via delayed NF-κB activationLife science alliance · 2026
Summary (written by the submitters)
Cellular senescence consists of regulated phenotypes associated with permanent exit from the cell cycle in response to stressors such as genomic instability. The consequences of senescence go beyond individual cells due to the senescence associated secretory phenotype (SASP), which can induce inflammation in neighboring cells. Some cancers respond to CDK4/6 inhibitors (CDK4/6i) with a senescence-like phenotype in the absence of extensive DNA damage.
Read the full summary ↓
We asked how the SASP and the transcriptional regulatory profile triggered by CDK4/6i-driven arrest compares to the canonical NF-κB-regulated SASP triggered by DNA damage. We profiled the dynamics of transcriptional regulation in response to the CDK4/6i, palbociclib, and the DNA damaging agent, doxorubicin. We found upregulation of NF-κB driven-SASP genes was shared across both drugs, although delayed in CDK4/6i, coinciding with slower enhancer activation and epigenetic changes. ATM/ATR inhibition did not affect CDK4/6i-induced NF-κB nuclear localization, suggesting an alternative upstream activator. Inhibiting NF-κB suppressed the expression of SASP genes without reversing stable arrest, pointing to SASP manipulation as a potential therapeutic strategy and providing insights into controversies regarding cell cycle arrest-driven SASP.

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 GSE295261_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.

Raw reads on ENA ↗

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 PRJNA1253960 and SRA study SRP580392. Searching any of these in the dataset finder brings you back here.
