Summary (written by the submitters)
Background. Oncolytic viruses represent promising cancer biotherapies due to their ability to selectively lyse tumor cells and stimulate anti-tumor immune responses. However, their long-term efficacy as single agents is inconsistent, underscoring the need for virus-drug combinations to improve outcomes. This study evaluates the effects and mechanisms of triptolide and minnelide in enhancing measles virus oncolysis in human colorectal cancer (CRC) models.

Methods. The in vitro effects of CD46 targeted (MV-GFP) and dual targeted (MV-CD46-muPA) oncolytic MV, alone and with triptolide were assessed in human CRC cell lines. Mechanistic studies included gene expression analysis, functional proteomics, and western blotting. In vivo efficacy of MV-CD46-muPA combined with minnelide was evaluated in HT-29 and HCT-116 xenografts. Biological effects were further characterized using transcriptomic profiling (RNA-seq), targeted gene expression (NanoString), and histological analysis . Results. Triptolide enhanced MV mediated oncolysis in vitro, particularly in BRAF mutant CRC cell lines, and modulated cancer pathways including AKT, autophagy, apoptosis and metabolism. In vivo, minnelide significantly improved the efficacy of systemically administered MV-CD46-muPA in human CRC xenografts, with greater effects in BRAF mutant (HT29) models. The combination modulated cell cycle, metabolism, and survival associated genes, promoted apoptosis, and improved intratumoral viral distribution. These molecular effects resulted in reduced tumor cell proliferation (Ki67), decreased angiogenesis (CD31) and increased apoptosis (TUNEL) relative to single agents. Conclusion. Triptolide and minnelide synergistically enhance the antitumor efficacy of oncolytic measles virus in colorectal cancer, particularly in BRAF mutant tumors through modulation of survival, metabolism and stromal pathways, together with improved viral distribution. These findings underscore the innovative potential of this virus-drug combination and support further translational development for CRC and other malignancies.

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 GSE312474_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 PRJNA1373568 and SRA study SRP651335. Searching any of these in the dataset finder brings you back here.
