Elucidating the mechanisms of early-stage breast cancer initiation

Using both transgenic cell lines and transgenic mouse models available in our research group, this project will determine the causal effects of increased accumulation of Reactive Oxygen Species (ROS) caused by HER2 overexpression on distinct stromal cell populations of mammary glands. These will be analysed using various state-of-the art omics methods, flow cytometry and various histological staining methods.

To determine the biological effects of the known epidemiological breast cancer risk factors (e.g. tissue stiffness, early menarche, late menopause, obesity, parity), this project will utilise both the transgenic animal models as well as 3D primary culture methods to elucidate their potential influence on alterations of tissue architecture, ROS or mutation rates during the earliest stages of HER2-driven breast tumourigenesis. These will be analysed using live-imaging methods, histology and whole-genome sequencing.

Supervisor's interests
The overall research direction of our group is to elucidate the mechanisms of breast tumorigenesis during its earliest pre-malignant stages, its progression to metastatic disease, and therapy response of breast tumours, with a particular focus on breast cancer stem cells. With a translational approach we then aim to develop novel preventive and curative treatments that can be used in clinics to improve the treatment outcomes for patients with breast cancer.

In relation to this PhD project, which is a continuation of our recent work (, 2024), we aim to better understand the role of the HER2 oncogene in the initiation of breast cancer through a non-cell autonomous mechanism, and to identify the molecular and cellular mechanisms underlying the effects of known epidemiological breast cancer risk factors on HER2-driven breast tumourigenesis.

Meet the Supervisor(s)

Ahmet Ucar - I am a senior lecturer in toxicology at the 成人直播app and an honorary research fellow at the University of Manchester and Manchester Breast Centre. My research vision is to provide a better understanding of the biology of breast cancer stem cells (BCSCs) with the aim of translating this knowledge into novel BCSC-targeting preventive and curative treatments. To this end, we use animal and cell models to study mammary gland development as well as initiation and progression of breast tumorigenesis.
