Personalized medicine utilizes an individual’s genetic and genomic make up to treat and prevent diseases. The promise of personalized medicine continues to grow as new scientific discoveries uncover previously unknown features and drug sensitivities for tumors. In a recent study, Dr. Aaron Udager, associate professor of genitourinary pathology and co-director of our PSTP program, was co-senior author on a publication with Dr. Sofia Merajver, professor of epidemiology and internal medicine and the director of the breast and ovarian cancer risk evaluation program. 

An article recently published by the Nuñez lab provides an exciting discovery for individuals with Alzheimer’s disease, diabetes, and certain other autoimmune diseases caused by aberrant NLRP3. The research, led by Dr. Jie Xu with Drs. Joseph Pickard and Gabriel Nuñez, discovered that a common, safe, FDA-approved drug used to treat alcoholism and cocaine addictions, disulfiram, inhibits the production of NLRP3 inflammasomes. When NLRP3 is activated, it can cause inflammation leading to multiple health issues.

Dr. Rohit Mehra, Professor and member of the Michigan Center for Translational Pathology (MCTP), and his international team of collaborators were recently recognized by the Asian Journal of Urology for the best paper published in their journal in 2023. This award-winning study is a literature overview of chromophobe renal cell carcinoma (ChRCC), the third most common RCC subtype.

A study from the University of Michigan Health Rogel Cancer Center furthers research that suggests the potential of developing new cancer treatments to target oncogenic transcription factors by indirectly affecting their ability to access enhancer DNA in chromatin. 

The findings appear in Cancer Cell.

Led by Arul Chinnaiyan, M.D., Ph.D., S.P. Hicks Professor of Pathology and director of the Michigan Center for Translational Pathology at Michigan Medicine, the research builds on previous work to find genetic vulnerabilities to treat transcription factor-driven cancers like prostate cancer.

To understand why some cancers successfully circumvent the immune system to grow unchecked, researchers turned to pregnancy.

“In pregnancy, the immune system does not reject the growing fetus, so we know there must be mechanisms active in the placenta. In cancer, it’s the same thing: the growing tumor is not rejected by the immune system. It means the cancer cells have developed strategies to suppress immune rejection, same as in pregnancy,” said Weiping Zou, M.D., Ph.D., professor of experimental pathology.

It’s a good thing in pregnancy – it allows the baby to grow. But in cancer, it means the tumor grows unchecked and treatments meant to stimulate an immune response are not effective.

The Division of Anatomic Pathology in the Michigan Medicine Department of Pathology offers grant funding for faculty and trainees to pursue research interests related to anatomic pathology that may not otherwise be funded. One of these internal AP grant-funded projects, led by first-author Eman Abdulfatah, MD and senior-author Rohit Mehra, MD, resulted in a recent cover story in Human Pathology entitled “Extragonadal germ cell tumors: A clinicopathologic study with emphasis on molecular features, clinical outcomes and associated secondary malignancies.”

Dr. Gabriel Nunez 's Lab Makes Breakthrough Discovery in Colitis

Crohn’s disease (CD), one of the major forms of Inflammatory Bowel Disease, is a chronic relapsing intestinal disorder that affects millions of people globally. The cause of CD is unknown, but it is thought to result from a dysregulated immune response against environmental factors, including intestinal microbes, in genetically susceptible hosts.

The critical role that the intestinal microorganisms, collectively known as the gut microbiota, plays in the pathogenesis of CD has been investigated over the past two decades. Given the importance of the gut microbiota in triggering CD, the development of therapeutic approaches that target disease-causing intestinal microbes may provide a unique approach to the treatment of this disease [...]

Dr. Julianne Szczepanski shares her story of parenting while working in healthcare.

A study from clinicians and researchers at the University of Michigan Rogel Cancer Center, U-M Department of Pathology and the Michigan Center for Translational Pathology reveals findings from over 800 clinical assays performed for kidney patients with MiTF family gene mutations.

After several decades of hard work by many scientists at the University of Michigan Medical School and elsewhere, an antibody (anti-C5a) has just been approved by the US FDA for treatment of humans who are septic and have developed lung infections with COVID-19, resulting in severe pulmonary dysfunction requiring external lung support. The antibody, anti-C5a, was originally developed in the Dr. Peter Ward laboratory in the early 2000s. The mAb was shown to dramatically reduce lung infections in polymicrobial sepsis in mice. 

A recently published research study led by Drs. Sem Phan and Tianju Liu from the Department of Pathology reported new findings that could help scientists predict disease progression and suggest a new immunotherapy target for the treatment of IPF and other fibrotic lung diseases.

These findings uncovered a new role for the immune checkpoint marker (B7-H3) in lung fibrosis that can potentially serve as a novel target for immunotherapy to slow down or abort the progression of lung fibrosis in patients with IPF and other chronic lung fibrotic diseases. In addition, sB7H3 levels in the plasma could serve as a potential marker to predict how quickly the disease progresses in patients and assess responsiveness to therapy, allowing for more informed treatment decisions.

Researchers from the Department of Pathology recently published a fascinating study into clinician’s perspectives on integrating pathologists into the patient’s care team in the form of pathology explanation clinics (PECs) [1]. Clinicians were asked, “How interested would you be in having your patient meet with a pathologist to discuss their pathology report and see their tissue under the microscope?”

As the SARS-CoV-2 virus continues to mutate over time and new booster vaccines become available, the question arises, are the multivalent boosters more effective at improving immune response than the monovalent vaccines with which we began? This question was addressed by a multi-site group from Columbia University Vagelos College of Physicians and Surgeons (New York) and from the University of Michigan Medical School Department of Pathology. Drs. Riccardo Valdez, Carmen Gherasim, and Aubree Gordon represented the Immunity Associated with SARS-CoV-2 (IASO) research team at U-M[...]

One of the most fascinating aspects of a career in cancer research is that one never knows when or where the next great discovery will occur. This was true of a recent breakthrough discovery made by the Dr. Russell Ryan laboratory at the University of Michigan Medical School. They were shocked to find that active regulatory elements in B-ALL contained not only typical protein binding sequences but also simple repeats of the sequence “GGAA”, usually considered a form of “junk DNA” with no regulatory function [...]

Members of the University of Michigan Department of Pathology and Michigan Center for Translational Pathology, in collaboration with the Clinical Proteomic Tumor Analysis Consortium, recently published a large study on clear cell renal cell carcinomas (ccRCCs), which represent about 75% of the RCC cases and account for the most RCC-associated deaths. This study set out to create a comprehensive profile of ccRCC, combining histologic and molecular profiles. By analyzing both the microscopic cell structures and the genetic makeup of the cells, these researchers discovered significant intratumoral heterogeneity in 90% of ccRCCs. This indicates that ccRCCs originate from multiple tumor cell lines, called tumor subclones, that may become metastatic and could independently influence response to therapies. Through this study, the team was able to molecularly stratify aggressive histopathic subtypes, which may lead to more effective treatment strategies for patients and improved survival.

For many of us, the idea of having blood drawn can be an unnerving thought. The use of needles and the sight of blood itself is not something we look forward to.
