Gut Microbe may Hold Potential in Treating Breast Cancer by Angela Mohan on January 7, 2021 at 3:45 PM
Colon microbes may play a role in the development of some breast cancers, according to new research from investigators with the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy.
In a series of laboratory experiments, researchers discovered that when enterotoxigenic Bacteroides fragilis (ETBF) was introduced to the guts or breast ducts of mice, it always induced growth and metastatic progression of tumor cells. A description of the work is published in the journal
Cancer Discovery.
While microbes are known to be present in body sites such as the gastrointestinal tract, nasal passages and skin, breast tissue was considered sterile until recently, says senior study author Dipali Sharma, Ph.D., a professor of oncology at Johns Hopkins Medicine.
FOR IMMEDIATE RELEASE
In what is believed to be the most comprehensive molecular characterization to date of the most common type of head and neck cancer, researchers from the Johns Hopkins departments of pathology and oncology, the Johns Hopkins Kimmel Cancer Center, the Johns Hopkins University School of Medicine, and 18 other centers around the U.S. and Poland have clarified the contribution of key cancer-associated genes, proteins and signaling pathways in these cancers, while proposing possible new treatment avenues.
Their deep-dive investigation of HPV-negative head and neck squamous cell carcinomas (HNSCCs), described in the Jan. 7 issue of the journal
Cancer Cell, involved tumors from 108 patients who had not yet received cancer treatment, and 66 samples of healthy tissue surrounding the tumors. The study systematically catalogued HPV-negative HNSCC-associated proteins, phosphosites (areas where they are modified by phosphate groups) and signaling pathways, finding three

A microbe found in the colon and commonly associated with the development of colitis and colon cancer also may play a role in the development of some breast cancers, according to new research from investigators with the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy. Breast tissue cells exposed to this toxin retain a long-term memory, increasing the risk for disease.
