Paper
Dual inhibition of sirtuins 1 and 2: reprogramming metabolic energy dynamics in chronic myeloid leukemia as an immunogenic anticancer strategyCancer communications (London, England) · 2024
Summary (written by the submitters)
The transcriptomic signature of chronic myeloid leukemia (CML) patients is characterized by heightened proliferation and mitochondrial metabolic activity. Sirtuin (SIRT)1 and SIRT2 are recognized as key regulators of metabolism homeostasis and cell proliferation/survival, and our network analyses unveiled their significant role in driving CML pathogenesis.

Accordingly, we demonstrated the therapeutic potential of dual SIRT1/2 inhibition across diverse models. In particular, we investigated the effect of a dual SIRT1/2 inhibitor, which exhibits selective efficacy against imatinib-sensitive and -resistant CML cells. To get a better understanding of Si-7111’s mechanism of action, we performed RNA-seq analysis on K-562 CML cells. The transcriptomic signature induced by Si-711 revealed that SIRT1/2 inhibition disrupted the regulation of crucial transcription factors, including MYC, associated with the reprogramming of hallmark pathways associated with CML cell proliferation. This reprogramming was characterized by metabolic alterations leading to energy depletion and subsequent induction of regulated necrosis.

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 GSE248894_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 PRJNA1046399 and SRA study SRP474830. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 of them. 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.
