Regulatory altas of cancer & circadian clock

Deciphering regulatory factors in cancer development and circadain clock through integrated analysis of (epi)genomic datasets with computational and statistical models

Roles of non-coding mutation in cancer development?

The computational trans-regulatory biology group led by Dr. Pengyi Yang at Charles Perkins Centre (CPC), University of Sydney, focuses on understanding the trans-omics networks that cut across signalling, transcriptional, translational and (epi)genomic regulations in controlling cell identities and cell-fate decision-making.

Molecular trans-regulatory programs comprised of cell signalling, transcriptional, translational, and epigenomic regulations are central to health and disease. Computational approaches are instrumental in characterising trans-regulatory programs of cells at the systems level. Our research lies at the interface of bioinformatics and systems biology. We develop computational and statistical models to reconstruct signalling cascades, epigenomics, transcriptional, and proteome networks, and characterise their cross-talk and trans-regulations in various cellular processes and systems. By integrating heterogeneous -omics data with the goal of generating testable hypotheses and predictions, our research contributes to the comprehensive understanding of trans-omic networks that underlie cellular homeostasis, proliferation, differentiation, and cell-fate decisions.
