RNA interference (RNAi), a highly conserved RNA silencing mechanism, plays pivotal roles in gene expression regulation, antiviral defense, and genome protection against transposon activity. Compared to the well-characterized small RNA interference pathways mediated by microRNAs (miRNAs) and exogenous small interfering RNAs (exo-siRNAs), current understanding of the processing, maturation, and f...

Animals endure many physical and social stressors throughout their lifetime and have evolved crucial mechanisms to cope with these challenges. The brain is one of the primary organs involved in perceiving and adapting to various stressors. However, it remains unclear how neurons initially sense stress or which downstream signaling pathways drive behavioral responses. Addressing these questions ...

Restrictive diets and regular exercise are cornerstone strategies for improving metabolic health and addressing chronic metabolic disorders such as obesity, type 2 diabetes, and sarcopenia. Despite their well-documented benefits, the shared molecular pathways underlying these interventions remain elusive.On January 2, 2025, Professor Yiguo Wang’s laboratory at the School of Life Sciences, Tsin...

Glucose homeostasis requires precise regulatory mechanisms to adapt to varying physiological conditions such as feeding, fasting, exercise, and stress. Glucagon, a hormone secreted by pancreatic α-cells, plays a crucial role in raising blood glucose levels during fasting. Despite being discovered over a century ago, the mechanisms underlying glucagon secretion have largely remained unclear—un...

The maintenance of glucose homeostasis is vital for survival and overall health. Although blood glucose levels in mammals fluctuate during feeding and fasting, they are typically maintained within a remarkably narrow range of 4–7 mM. This precise balance is achieved through the coordinated actions of multiple tissues. While numerous hormones that stimulate glucose production have been identifi...

The CRISPR-Cas system has become one of the most widely used tools in gene editing, allowing precise targeting and cleavage of DNA through RNA-guided Cas proteins. Recent advancements in bioinformatics and biochemistry have significantly expanded our understanding of the diversity within CRISPR systems, particularly in type V, which rely on the highly conserved RuvC nuclease domain for target c...

Dynamic properties are essential for microtubule (MT) physiology, which depend on the polymerization and spontaneous depolymerization of tubulin isotypes at the MT ends. Mutations in tubulin-coding genes cause human diseases collectively designated as ‘tubulinopathies’. As a result, live-cell imaging of tubulins is crucial for understanding the dynamic regulation of MTs and elucidating their ...

In mammals, female (XX) and male (XY) cells exhibit sex chromosome dimorphism. To achieve dosage compensation of X-linked genes, female cells undergo X chromosome inactivation (XCI) during early embryo development. Abnormal XCI leads to severe developmental defects such as intellectual disabilities in humans and even embryonic lethality. Hence, investigating the mechanisms of XCI is of both sci...
