Scientific discovery alone is not enough.
Research becomes meaningful only when it can be understood,
compared,
reproduced,
and reinterpreted across time.
At NOSTER,
we believe that scientific progress depends not only on new discoveries,
but also on the foundations that make those discoveries referenceable.
For this reason,
our research is guided by four fundamental principles.

These principles form the scientific foundations of every research program at NOSTER.

Every experiment produces data.
Not every experiment produces knowledge.
Scientific knowledge emerges only when discoveries can be interpreted within a common
framework,
compared with previous findings,
and connected to future research.
Without shared foundations,
research becomes isolated.
Without comparability,
knowledge cannot accumulate.
Without accountability,
scientific discoveries lose their lasting value.
At NOSTER,
we regard research not as a collection of experiments,
but as the design of knowledge that remains meaningful beyond the present.

Metabolites are among the most direct molecular reflections of biological activity.
They reveal how living systems respond to nutrition,
microbial metabolism,
environmental influences,
and host physiology.
Rather than observing disease itself,
metabolite science seeks to understand the molecular relationships that underlie biological states.
At NOSTER,
gut microbial metabolites represent one of the most important molecular interfaces between the external environment and human biology.
By studying these molecular transformations,
we seek to understand how biological balance is established,
maintained,
and ultimately restored.

The human gut microbiota continuously transforms dietary components into diverse bioactive molecules.
These transformations generate numerous classes of metabolites, including:

These molecules participate in complex biological processes associated with metabolism,
immune regulation,
intestinal barrier function,
inflammatory responses,
and other physiological systems.
Rather than investigating individual metabolites in isolation,
our research focuses on understanding the relationships among these molecules as components of integrated biological networks.
This systems-oriented perspective forms the basis of metabolite science at NOSTER.

Biological states cannot be observed directly.
What can be measured are the molecules participating in those states.
Metabolites provide measurable molecular information that helps explain how biological systems change over time.
Within NOSTER,
metabolites are not regarded merely as biomarkers.
They are molecular components that participate in the formation,
maintenance,
and transition of biological states.
Understanding these molecular relationships enables us to interpret biological states as dynamic structures rather than static labels.
This scientific perspective provides the conceptual foundation for:

Together,
these initiatives extend metabolite science from molecular discovery to real-world implementation.

Metabolite science is still an emerging discipline.
Its future depends not only on new discoveries,
but also on establishing common scientific foundations that allow research to remain
comparable,
interpretable,
and cumulative.
At NOSTER,
our objective is not simply to discover new molecules.
It is to build the scientific foundations upon which future discoveries can be built.

Scientific discovery does not end with identifying a molecule.
Its significance lies in understanding
how that molecule participates in biological systems
and contributes to the regulation of human health.
At NOSTER,
we investigate how gut microbial metabolites influence host physiology through interactions among metabolites,
cells,
tissues,
and biological networks.
Rather than focusing on isolated molecular events,
our research seeks to understand biological mechanisms as interconnected systems.

Every metabolite has a biological context.
Its significance cannot be understood solely through its chemical structure or concentration.
Instead,
its biological role emerges through interactions with receptors,
cells,
signaling pathways,
and surrounding molecular environments.
Understanding these interactions allows molecular discoveries
to become biological knowledge.
This progression—from molecule to mechanism—is a central principle of metabolite science.

HYA was the first gut microbial lipid metabolite systematically investigated by NOSTER.
Beginning with its discovery,
our research has progressively clarified:

HYA represents more than a single metabolite.
It serves as a reference case demonstrating how metabolite science can connect molecular
discovery,
mechanistic biology,
drug discovery,
and future healthcare.

Biological responses rarely depend on a single molecule.
They emerge from coordinated interactions among many molecules operating simultaneously.
Gut microbial metabolites participate in interconnected biological systems involving:

Understanding these relationships allows biological states to be interpreted as dynamic systems rather than isolated molecular events.
This systems perspective underlies all mechanistic research at NOSTER.

Mechanistic research does more than explain biological phenomena.
It provides the scientific foundation upon which future discoveries,
therapeutic development,
and clinical translation become possible.
At NOSTER,
mechanism is not regarded as the conclusion of research.
It is the bridge between molecular discovery and real-world implementation.

Our collaborative research spans the full continuum of scientific discovery,
from fundamental biology to clinical research,
preventive medicine,
and translational science.
Together with our partners,
we investigate the roles of gut microbial metabolites in human health and disease,
while building new scientific foundations for future healthcare.
Representative collaborators include:

These collaborations connect fundamental science,
clinical validation,
and real-world implementation.

Metabolite science is inherently global.
NOSTER actively collaborates with leading international researchers and institutions to deepen scientific understanding and accelerate innovation.
Our international collaborations include:

Through these partnerships,
scientific knowledge is shared,
expanded,
and translated into future healthcare.

Scientific credibility is established through carefully accumulated evidence.
Over the past decade,
NOSTER and its collaborators have contributed to the emerging field of gut microbial metabolite science through internationally recognized publications.
Together,
these studies demonstrate how metabolite science progresses from molecular discovery,
to biological understanding,
to drug discovery,
and ultimately toward future healthcare.

Our research continues to expand across multiple areas of metabolite science, including:

These studies are conducted in collaboration with academic institutions and clinical partners worldwide.

Every publication marks the beginning of new scientific questions.
Knowledge advances through continuous verification,
comparison,
and reinterpretation.
At NOSTER,
we regard publications not as final answers,
but as milestones within an ongoing scientific journey.

Research is more than discovery.
It is the creation of scientific foundations that others can understand,
verify,
and build upon.
At NOSTER,
we integrate molecular biology,
microbiology,
analytical technologies,
and reference systems to advance metabolite science from discovery to implementation.
Our goal is not simply to produce new findings.
It is to establish scientific foundations that will continue to shape the future of medicine,
health,
and life science.
