BioPitNeT
The National Biorepository and Resource for Pituitary Neuroendocrine Tumor Translational Research (BioPitNeT)
An open source, clinically relevant deep tumor phenotyping platform and biorepository
Introduction to BioPitNeT
Chronic hypercortisolism resulting from an adrenocorticotropic hormone (ACTH)-secreting Pituitary Neuroendocrine Tumor (PitNET), or Cushing’s disease exerts numerous detrimental health effects, including increased cardiovascular events, strokes, hypertension, diabetes, obesity, depression, anxiety, and increased risk of cancer and death. Despite decades of research, current treatments for Cushing’s disease remain suboptimal, with substantial unmet needs in translational research. The development of targeted therapies is challenging due to limited knowledge of the molecular mechanisms of tumorigenesis (normal cells transforming into cancer cells) and heterogeneity (differences between cancer cells within a tumor.) The rarity and biological complexity of Cushing’s disease requires collaboration among multiple centers and interdisciplinary teams of translational scientists and clinical investigators.
In 2024, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) awarded our interdisciplinary team the RC2 High Impact, Interdisciplinary Science in NIDDK Research Areas grant to establish BioPitNeT.

From Patient to Pioneer:
What Didn’t Kill Me Made My Science Stronger
I was diagnosed with Cushing disease in 2020, but I had lived with the symptoms for almost 20 years—chronic fatigue, nausea, depression, and dangerously high blood pressure. Even after finally getting surgery, I learned that treatment often fails or the disease comes back. It was frustrating to realize that, despite decades of research, only small steps have been made in improving care. As both a patient and a scientist, I saw how rare diseases like Cushing’s are often overlooked, and how working in separate “research silos” holds back progress.
My personal experience pushed me to take action. I started BioPitNeT to help researchers and doctors work together to better understand pituitary tumors called PitNETs, which cause Cushing disease. By sharing tools and data, we can speed up diagnosis, improve treatment, and raise awareness. I want to make sure others don’t have to wait years for answers like I did. My mission now is to turn pain into progress—for myself, for patients, and for science.

Study Aim 1
To establish the BioPitNeT centralized biorepository consisting of resources that will be benchmarked to the patients’ PitNET tissue of origin

Study Aim 2
To develop a PitNET clinically relevant classification system for Cushing’s Disease

Study Aim 3
To establish induced pluripotent stem cell (iPSCs) lines genetically engineered to model corticotroph subtype PitNETs as a resource for investigating genetic underlying mechanisms of Cushing’s Disease
The BioPitNeT Team
BioPitNeT will be the first biorepository and resource generated by a prospective, multi-institutional consortium to overcome the challenges of effectively treating Cushing’s Disease by facilitating clinically relevant, translational research and raising awareness through community engagement and patient advocacy. Meet the team and their areas of expertise for the project.
