Overview

Giancarlo Marra is affiliated with the University of Zurich in Switzerland and has contributed extensively to research in the fields of biochemistry, genetics, molecular biology, and medicine. Their work spans a variety of subfields including molecular biology, cancer research, oncology, genetics, and pulmonary and respiratory medicine.

The scientist's primary research topics include epigenetics and DNA methylation, genetic factors in colorectal cancer, colorectal cancer screening and detection, cancer-related molecular mechanisms, renal cell carcinoma treatment, cancer genomics and diagnostics, as well as the interplay of cancer, hypoxia, and metabolism.

Recent scholarly publications by Giancarlo Marra encompass a range of studies in oncology and molecular biology. Notable papers are:

  • Antiangiogenic immunotherapy suppresses desmoplastic and chemoresistant intestinal tumors in mice, 2020, Journal of Clinical Investigation
  • Functional Analysis Identifies Damaging CHEK2 Missense Variants Associated with Increased Cancer Risk, 2021, Cancer Research
  • DAMEfinder: a method to detect differential allele-specific methylation, 2020, Epigenetics & Chromatin
  • The DNA hypermethylation phenotype of colorectal cancer liver metastases resembles that of the primary colorectal cancers, 2020, BMC Cancer
  • Transrectal versus transperineal prostate fusion biopsy: a pair-matched analysis to evaluate accuracy and complications, 2024, World Journal of Urology

Collaboration is a significant aspect of Marra's career, with frequent co-authors including Paolo Gontero, Stephany Orjuela, Mark D. Robinson, Giorgio Calleris, and Marco Oderda. These collaborations likely span several aspects of cancer research and molecular diagnostics.

Giancarlo Marra's research has been published repeatedly in prominent venues, with multiple publications in journals such as:

  • BMC Cancer
  • World Journal of Urology
  • bioRxiv (Cold Spring Harbor Laboratory)
  • The Journal of Urology
  • Research Square (Research Square)

The breadth of Marra's research reflects an intersection of genetics and cancer biology, with an emphasis on the molecular mechanisms underlying cancer and its detection, notably colorectal and renal cell carcinomas. This work contributes to understanding genetic variants related to cancer risk and epigenetic changes that characterize cancer progression and metastasis.
