Inhibition of MBTPS1 enhances antitumor immunity and potentiates anti-PD-1 immunotherapyNature communications · 2025
Summary (written by the submitters)
Despite notable advancements in cancer immunotherapy, the overall response rate among cancer patients remains low. Therefore, exploring strategies combining immunotherapy with adjuvant approaches to augment adaptive immune responses, such as by boosting the infiltration of T lymphocytes, is an attractive strategy. To pinpoint key regulators of tumor immunity, we developed a focused single guide RNA (sgRNA) library targeting membrane and secreted protein genes.

Utilizing this library, we conducted an in vivo clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 screen in colorectal cancer mice model. We revealed that the loss of MBTPS1 in tumor cells enhanced anti-tumor immunity and synergized with anti-PD-1 therapy. Mechanistic studies uncovered that tumor cell-intrinsic MBTPS1 could compete with USP13 for binding with STAT1, thereby disrupting the USP13-dependent deubiquitination and stabilization of STAT1. MBTPS1 deficiency induced CXCR3+ CD8+ T cells infiltration in the tumor microenvironment by upregulating mRNA levels of Cxcl9, Cxcl10 and Cxcl11 transcribed by STAT1. Our study revealed that targeting MBTPS1 in cancer cells could turn cold tumors into inflamed ones, thereby enhancing the efficacy of anti-PD-1 blockade.

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 GSE263524_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1097966 and SRA study SRP500502. Searching any of these in the dataset finder brings you back here.
