A*STAR IMCB Researchers Awarded NRF CRP Funding to Advance Research in Neurodegeneration and Drug Resistance
A*STAR’s Institute of Molecular and Cell Biology (IMCB) congratulates Dr. Ng Shi Yan and Dr. Tee Wee-Wei, Senior Principal Investigators at A*STAR IMCB, on being awarded the prestigious National Research Foundation (NRF) Competitive Research Programme (CRP) from the CRP31 grant call. The NRF CRP funding scheme supports multi-disciplinary teams to conduct cutting-edge research projects that are of relevance to òòò½Íøand the society. These two A*STAR IMCB-led projects exemplify the institute’s ongoing commitment to tackling complex biomedical challenges through scientific excellence and innovation.

Investigating Microglia-Based Targets in Neurodegeneration
Neuroinflammation is a hallmark of many age-onset neurodegenerative diseases, yet current therapies do not specifically halt its neurotoxic effects. To address this, Dr. Ng Shi Yan and her team are developing a novel culture model in which neural organoids—miniature brain-like structures—are infused with microglia, the immune cells of the brain. This immuno-competent organoid system allows researchers to better mimic disease conditions and study how immune dysregulation contributes to disease progression.

Focusing initially on amyotrophic lateral sclerosis (ALS), the team aims to identify drug targets that reduce the harmful effects of pro-inflammatory microglia—an important driver of disease pathology. The approach holds broader implications for other neurodegenerative diseases involving similar immune-mediated mechanisms.

“We believe that these findings will also be applicable to other neurodegenerative diseases such as Alzheimer’s and other forms of dementias,” said Dr. Ng. With this model, the team is well-positioned to uncover new therapeutic strategies for complex brain disorders.

Uncovering Drug-Tolerant Cell States in Cancer
Despite major investments in cancer research and the development of numerous anti-cancer therapies, drug resistance remains a formidable barrier in precision medicine. Resistance can be inherent, where there is no initial clinical response, or acquired, where tumours relapse after an initial period of treatment success. These resistance mechanisms severely limit the durability of therapeutic responses and pose a key challenge in oncology.

Dr. Tee Wee-Wei and his team aim to address this challenge through a project titled “DEBUT: Discovering Novel Biomarkers and Unveiling Therapeutic Vulnerabilities in Drug-tolerant Persister (DTP) cells.” The study adopts a comprehensive approach to dissect the full trajectory of cancer cell resistance, with a particular focus on a subset of cells known as drug-tolerant persister (DTP) cells. These rare but clinically significant cells can survive treatment and eventually drive tumour recurrence.

The project seeks to identify predictive biomarkers and therapeutic vulnerabilities across distinct resistance states—including persister populations—to better understand the underlying biology of resistance. By uncovering these mechanisms, the team aims to directly inform clinical decision-making and support the development of more durable, personalised cancer therapies that can improve long-term patient outcomes.
