NIH-funded scientists uncover clues to precancer and tumor biology

New insights from multiple studies provide critical information on how cancer tumors develop, spread, and respond to treatments. The 10 studies from the Human Tumor Atlas Network (HTAN), a National Institutes of Health (NIH)-funded Cancer Moonshot^SM initiative to construct three-dimensional maps of human tumors, published across a number of Nature journals.

Several studies explore the role of the tumor microenvironment and the immune system in promoting the spread of cancer and its resistance to treatment. Three studies map the trajectory of precancerous colorectal tissues toward cancer by measuring the contributions of multiple molecular and cellular events. Multiple new HTAN papers describe the development of innovative single-cell technology and analysis platforms.

Launched in 2018, HTAN constructs three-dimensional maps of human tumors that capture their molecular features and surrounding microenvironments over time. The work is being done by teams of investigators from research institutions across the country using a variety of technologies and computational approaches to study tumors at the single-cell level. This comprehensive, publicly available resource aims to help researchers better understand the development and progression of cancer to inform its prevention and treatment. The first tumor atlas studies from this initiative were published in 2020 and 2021.

What people thought about us

“As Director of Surgical Services Departments there has been considerable changes have occurred in my department and Anesthesia Experts has always risen to meet our demands of our facility. They have been very pro-active in meeting the increase volumes allowing us to keep our surgeons and patients very satisfied with our services.”

“Before AE took over the anesthesia department was described by the surgeons as the worst in the history of our hospital. The prior management company was having a cancelled surgery per day. I am happy to report there has not been one since they have taken over the department. Additionally we have seen a 905 reduction if requested preop
lab tests. The anesthesia department is now the very best hospital department in our entire facility.”

“Anesthesia Experts has provided consistent anesthesia providers who display a high degree of integrity, responsibility and professionalism. They have become a more valuable part of our facility and community.”

LR CEO 150 beds TX

“Even though they are physically located 1000 miles away Anesthesia Experts just does not provide great anesthesia coverage they personally engage surgeons to increase their business. Last year my surgical volume rose by 24% and we are currently 50% ahead of last year and all of that growth is organic.”

JE FACHE CEO AL 92 bed hospital

“Anesthesia Experts is more responsive than anyone I have dealt with. They are available by phone whenever needed and will be on site for any need or request and has been on site to address issues before we can make the request.”

SW CEO 25 beds NM

“While problems are extremely rare when they do occur Anesthesia Experts quickly and professionally implements a solution. Our surgical volume has grown over 100 cases per month and now our GI docs want to perform all of their endoscopies in our hospital instead of their GI lab that they own!”

SP CEO 346 beds AL

“Our anesthesia department was a thorn in my side that kept me awake at night. Anesthesia Experts swept in and brought order to our mess and our department was quickly redirected.”
