arXiv:2606.00568v1 Announce Type: new Abstract: Bulk gene expression profiling, which aggregates pooled RNA across cells within a biological sample, remains important in the single-cell era because it is typically less noisy, more sensitive, and more cost-effective than single-cell assays. Accordingly, a growing body of computational methods seeks to recover causal relations among genes from bulk expression data. However, aggregation is a lossy, non-invertible coarsening of the underlying cellular system, and it remains unclear whether and under what conditions causal relations are recoverable
The proliferation of bulk gene expression data and the increasing sophistication of computational methods make the recovery of causal relations from this data a timely and critical area of research.
Understanding the limits and conditions for recovering causal genetic relationships from bulk data directly impacts drug discovery, therapeutic development, and our fundamental understanding of biological systems.
This research clarifies the reliability of insights derived from prevalent bulk gene expression data, potentially validating or challenging existing computational methods and informing future experimental design.

Improved computational tools will emerge to more accurately infer causal gene relations from bulk expression data, increasing the utility of existing datasets.
More reliable causal models will accelerate the identification of novel drug targets and the development of targeted therapies for complex diseases.
This precision in genetic understanding could ultimately lead to a paradigm shift in personalized medicine, where treatments are highly customized based on individual causal gene networks.
