Mayo Clinic researchers link ovarian cancer to bacteria colonization in microbiome

A specific colonization of microbes in the reproductive tract is commonly found in women with ovarian cancer, according to a new study from Mayo Clinic’s Center for Individualized Medicine. The discovery, published in Scientific Reports, strengthens evidence that the bacterial component of the microbiome — a community of microorganisms that also consists of viruses, yeasts and fungi — is an important indicator for early detection, diagnosis and prognosis of ovarian cancer.

Trailblazing scientists discuss exposome research, precision nutrition at Mayo Clinic’s Individualizing Medicine Conference  

The next frontier in individualized medicine is here. Mayo Clinic’s 11th annual Individualizing Medicine Conference on Nov. 2–3 will focus on “Exploring the Exposome” — the cumulative measure of environmental influences and associated biological responses throughout the life span of a person, and how those exposures relate to health and disease.  

Research provides critical information about the size and growth speed of gliomas

An important new clue for preventing and treating brain tumors known as gliomas has been identified in research led by the Lunenfeld-Tannenbaum Research Institute (LTRI) at Mount Sinai Hospital in Toronto and Mayo Clinic Comprehensive Cancer Center and Mayo Clinic Center for Individualized Medicine. The study, published in the journal Science, provides a rare window into the biological changes behind glioma development.

Mayo Clinic researchers identify drug resistance factors for advanced prostate cancer

In a new study published in Molecular Cancer Research, Mayo Clinic researchers identified critical genomic changes in response to abiraterone acetate/prednisone, a standard treatment option for men with progressive, incurable and castration-resistant prostate cancer.

Lack of diversity in genomic databases may affect therapy selection for minority groups

Low representation of minority groups in public genomic databases may affect therapy selection for Black patients with cancer, according to new Mayo Clinic research published in npj Precision Oncology.

The researchers investigated the use of genomic databases and found that tumor mutation burden was significantly inflated in Black patients compared to White patients.

As a result of the study, clinicians who are using public genomic databases need to be aware of the potential for inflated tumor mutation burden values and how that may affect therapy selection and outcomes, especially for patients from underrepresented groups.

Mayo scientists develop mathematical index to distinguish healthy microbiome from diseased

What causes some people to develop chronic diseases such as rheumatoid arthritis, cancer and metabolic syndrome while others stay healthy? A major clue could be found in their gut microbiome — the trillions of microbes living inside the digestive system that regulate various bodily functions.
