With 20 subtypes of Renal Cell Carcinoma (RCC) listed by the World Health Organization in 2022, determining the specific type of RCC and the correct treatment protocol for patients can be daunting. Only seven of the 20 subtypes had been defined by specific molecular changes and the 20% of RCCs that are classified as non-clear cell RCCs (non-ccRCC), were primarily identified only by histopathologic features. The driving genetic changes had not been identified. A large multi-institutional team making up the Clinical Proteomic Tumor Analysis Consortium, including several researchers from Michigan Medicine’s Department of Pathology, performed multi-omics data analysis on 48 non-ccRCC and 103 ccRCC tumors as well as 101 normal adjacent tissues to study the genetic aberrations found in these tumor types. The findings of this research were recently published in Cell Reports Medicine, with Pathology’s Drs. Alexey Nesvizhskii and Saravana Mohan Dhanasekaran as senior authors and Dr. Ginny Xiaohe Li as first author.
Molecular and Cellular Pathology Graduate Student Michael Pitter successfully defended his PhD thesis on March 15, 2024, and officially became Michael Pitter, PhD, MS. Pitter completed his thesis research in the laboratory of Dr. Weiping Zou, the Charles B. de Nancrede Professor, Professor of Pathology and Surgery. Pitter’s thesis, “The Role of Peptidyl Arginine Deiminases in Regulating Anti-tumor Responses in Immune Cells” reports on his research which demonstrated that PAD2 and PAD4 enzymatic activity supported tumor growth and when inhibited, may serve as a novel target in the treatment of cancer. He also discovered that PAD4 citrullinated STAT1, controlling STAT1 transcriptional activity, and consequently, MHC-II expression and function in macrophages. This work featured multiple novel findings in macrophage biology which may be exploited for the treatment of cancer and was published in Cell Reports.
Please join us in congratulating Dr. Michael Pitter on the successful completion of his PhD!
In a manuscript published this week in JAMA Oncology, senior author Dr. Arul Chinnaiyan and members of the EDRN-PCA3 Study Group reported on their development and validation of a new 18-gene urine-based test for diagnosis of high-grade prostate cancer, MPS2. This test was initially developed in the Department of Pathology.
University of Michigan Rogel Cancer Center researcher Arul Chinnaiyan, MD, PhD, has received a $5 million grant from the J.C. Kennedy Foundation to conduct laboratory tests of a potential drug candidate targeting a master regulator that controls the majority of genes involved in the most challenging type of prostate cancer. The SWI/SNF chromatin remodeling complex was previously found to facilitate access to enhancers that oncogenes can bind to, driving downstream gene expression in cancer. Degrading a subunit of this complex blocks the oncogenes [...]
