Thea D. Tlsty is an American pathologist and professor of pathology at the University of California, San Francisco (UCSF). [1] She is known for her research in cancer biology and her involvement in the discovery of cells that may be at the origin of metaplastic cancer, an invasive form of breast cancer. [2]

Education

Tlsty earned her bachelor's degree in zoology from the University of South Florida, Tampa in 1973. She began her doctoral studies in molecular biology at the University of North Carolina, Chapel Hill before transferring to Washington University in St. Louis, where she received her PhD in 1980. [3]

Career

Tlsty stayed at Washington University for a short postdoctoral fellowship position, until 1981. She then joined Stanford University as a postdoctoral fellow/senior research associate in the department of biological sciences. In 1985, Tlsty returned to the University of North Carolina as an Assistant/Associate Professor of Pathology at the UNC Lineberger Comprehensive Cancer Center.

Since 1994, Tlsty has been Professor of Pathology at the University of California, San Francisco (UCSF). She is Director of the Center for Translational Research in the Molecular Genetics of Cancer. [3]

Research

Tlsty led an eight-year research study, published in the Journal of the National Cancer Institute in 2010, which established a means to predict whether women with early stage breast cancer might develop more serious tumors, using "biomarkers" (biological indicators in the body) to determine cancer risk. [4] [5] Tlsty also led research into 'pluripotent' stem cells in breast tissue, seeking to identify if these caused tumors. [6] This research had looked at wound cells in breast tissue, and identified 'repair cells' that could transform into a range of other cells, including neurons, bone and cartilage [7] [8] — with the potential therefore to also treat cancers and other diseases. [9] [10]

In 2015, she co-authored research into the use of 3D tissue culture models to study breast cancer cell generation [11] and later collaborated with Adam Engler of the University of California, San Diego in developing devices to test how strongly cells attach to tumor tissue, exploring if adhesion strength could be an accurate marker of metastatic cells. [12]

Tlsty was awarded a 2019 Cancer Research UK Grand Challenge award of £20 Million (U.S. $26 million) to support a research project in collaboration with scientists from the UK, Canada, and Israel. [13] [14] The project will focus on understanding how chronic inflammation contributes to cancer. [15] [16] [17]

In medicine, desmoplasia is the growth of fibrous or connective tissue. It is also called a desmoplastic reaction to emphasize that it is secondary to an insult. Desmoplasia may occur around a neoplasm, causing dense fibrosis around the tumor, or scar tissue (adhesions) within the abdomen after abdominal surgery.

Metastatic breast cancer, also referred to as metastases, advanced breast cancer, secondary tumors, secondaries or stage IV breast cancer, is a stage of breast cancer where the breast cancer cells have spread to distant sites beyond the axillary lymph nodes. There is no cure for metastatic breast cancer; there is no stage after IV.

The Physical Sciences in Oncology Network (PS-ON) is a network of centers and projects set up by the National Institutes of Health (NIH) National Cancer Institute (NCI) to link the physical sciences with the study of cancer. The program was launched in 2009 with Physical Sciences in Oncology Centers (PS-OCs) investigating complex and challenging questions in cancer research from a physical sciences perspective. To explore how the NCI could continue to support the integration of physical sciences and cancer research, a Think Tank and series of Strategic Workshops were held in 2012. These meetings served to update opportunities at the interface of physical sciences and cancer research and guided the development of the second phase including Physical Sciences in Oncology Projects (PS-OPs).

Patient derived xenografts (PDX) are models of cancer where the tissue or cells from a patient's tumor are implanted into an immunodeficient or humanized mouse. It is a form of xenotransplantation. PDX models are used to create an environment that allows for the continued growth of cancer after its removal from a patient. In this way, tumor growth can be monitored in the laboratory, including in response to potential therapeutic options. Cohorts of PDX models can be used to determine the therapeutic efficiency of a therapy against particular types of cancer, or a PDX model from a specific patient can be tested against a range of therapies in a 'personalized oncology' approach.

She was also the co-leader of the Cancer, Immunity, and Microenvironment Program at the Hellen Diller Family Comprehensive Cancer Center and a member of the Executive Committee of the Sabre-Sandler Asthma Basic Research Center at UCSF. Her research focused on features of the microenvironment surrounding cells, with particular interest in the extracellular matrix and the role of its protease enzymes in cell signaling.

A cancer-associated fibroblast (CAF) is a cell type within the tumor microenvironment that promotes tumorigenic features by initiating the remodelling of the extracellular matrix or by secreting cytokines. CAFs are a complex and abundant cell type within the tumour microenvironment; the number cannot decrease, as they are unable to undergo apoptosis.
