New Co-expression Network Analysis Method SGCRNA Developed by Okayama University to Visualize Hidden Relationships

New Analytical Method SGCRNA by Okayama University

On February 22, 2026, Okayama University announced a groundbreaking co-expression network analysis method named SGCRNA. Developed by Professor Takeshi Takarada from the Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, this innovative approach aims to visualize relationships that traditional methods may overlook.

Addressing Existing Challenges in Network Analysis

For about 20 years, the Weighted Gene Co-expression Network Analysis (WGCNA) method has been widely used in genetic research. However, recent criticisms have emerged regarding its underlying theories and the mathematical assumptions it relies on. As a response to these challenges, SGCRNA re-examines and improves upon existing frameworks, offering a finer and more interpretable extraction of modular relationships within complex datasets.

This new method has shown great promise in validating various analytical approaches using public data, thus demonstrating its efficacy in enhancing the precision of disease etiology exploration and drug target discovery.

High-Quality Validation and International Recognition

SGCRNA's development has been recognized by its publication in the well-regarded international journal, "Briefings in Bioinformatics," reflecting its significant contribution to the field of bioinformatics. By revealing important gene interactions that may go unnoticed, SGCRNA lays the groundwork for a more detailed understanding of disease mechanisms and the advancement of precision medicine.

Looking Toward the Future

Moving forward, Professor Takarada and his team are aiming to expand the application of SGCRNA to large-scale datasets, including efforts to accelerate analysis speeds, perform experimental verifications, and facilitate drug target and biomarker searches. This expansion will help integrate SGCRNA into practical medical research and potentially lead to significant advancements in the precision of therapeutic strategies.

The unveiling of SGCRNA was part of a routine press conference held by Okayama University, showcasing the university's commitment to academic and research excellence.

Research Funding and Collaborative Initiatives

This research was supported by various funding sources, including grants from the Japan Society for the Promotion of Science (23K14384, 23K08677, 23K21368), the Japan Agency for Medical Research and Development (AMED JP24bm1123059), and support from the Exploratory Research for Advanced Technology (FOREST JPMJFR225H).
