Valerie Speirs is a Professor of Molecular Oncology at the University of Aberdeen. [1] Her research aims to identify biomarkers of breast cancer to inform diagnosis and treatment. [3] [4]
Speirs studied zoology at the University of Aberdeen. [5] She completed her graduate studies at the University of Glasgow. [6] [5] She worked with Ian Freshney on cell culture and became interested in how cell culture systems can be used to model disease. [2]
Speirs research investigates Cancer biology, Breast cancer and Molecular pathology. [1] [3] [4]
Speirs joined The Hospital for Sick Children.[ when? ] Speirs worked at the University of Hull on the expression of oestrogen receptor mRNA. [7] [8] She looked at the role of the CGA gene in endocrine response. [9]
Speirs was a member of the Breast Cancer Campaign Scientific Advisory Board in 2008. [10] She joined the Irish Health Research Board in 2009. [10] She served as principal investigator of the Leeds Breast Cancer Campaign Tissue Bank. [5] She oversaw the launch of the tissue bank with the cancer research community in 2012. [5] The tissue bank was a founding member of the Breast Cancer Now tissue bank. [11]
Speirs joined the University of Leeds in 2012. Since then she has been a member of the Sloane Project steering group, a five year study of 1,000 women. [12] As lead of the St James's University Hospital Institute of Cancer & Pathology, Speirs looked to transfer lab-based molecular pathology techniques into the clinic for the identification of breast carcinoma in men and women. [13] She serves on the advisory group of the National Cancer Research Institute biomarkers advisory group. [10] She studies oestrogen receptor biology and endocrine resistant breast cancer. [14] She has looked to identify the biomarkers for male breast cancer, finding that the androgen receptor biomarker had prognostic significance. [15] She found that male breast cancers over-express eukaryotic initiation factors. [16] She developed a series of resources to educate nurses in observing breast cancer. [17]
In 2016 Speirs launched the virtual resource Sharing Experimental Animal Resources: Coordinating Holdings in Breast Cancer (SEARCHBreast), a platform to share materials that are surplus to animal studies of breast cancer. [18] [19] [20] The project was part of a NC3R grant to develop smart approaches to reduce animal use in science. [21] The resources are available for the characterisation of tumour biomarkers and to investigate the effect of treatment. [22] In 2018 Speirs joined the University of Aberdeen. She holds a visiting lectureship at the University of Leeds. She is a member of the Cellular Molecular Pathology initiative of National Cancer Research Institute. [18] [11] She is working with James Boyne at the University of Bradford on miRNA using blood and breast cancer tissues from the Breast Cancer Tissue Bank. [23] They will investigate how endocrine disrupting agents modulate the activity of fibroblasts in high and low mammographic density breast tissue. [24] They use a 3D in vitro model of the human mammary gland. [24] By identifying how oestrogen mimics effect human fibroblasts from areas of different breast density it will be possible to identify how the drives breast cancer development. [24] She has published extensively on breast cancer and has a h-index of over 40. [25] She is associate editor for BMC Cancer .[ citation needed ]
Speirs was elected a Fellow of the Royal College of Pathologists (FRCPath) in 2007. [5]
Tamoxifen, sold under the brand name Nolvadex among others, is a selective estrogen receptor modulator used to prevent breast cancer in women and men. It is also being studied for other types of cancer. It has been used for Albright syndrome. Tamoxifen is typically taken daily by mouth for five years for breast cancer.
Invasive carcinoma of no special type, invasive breast carcinoma of no special type (IBC-NST), invasive ductal carcinoma (IDC), infiltrating ductal carcinoma (IDC) or invasive ductal carcinoma, not otherwise specified (NOS) is a disease. For international audiences this article will use "invasive carcinoma NST" because it is the preferred term of the World Health Organization (WHO).
Receptor tyrosine-protein kinase erbB-2 is a protein that normally resides in the membranes of cells and is encoded by the ERBB2 gene. ERBB is abbreviated from erythroblastic oncogene B, a gene originally isolated from the avian genome. The human protein is also frequently referred to as HER2 or CD340.
Intracrine refers to a hormone that acts inside a cell, regulating intracellular events. In simple terms it means that the cell stimulates itself by cellular production of a factor that acts within the cell. Steroid hormones act through intracellular receptors and, thus, may be considered to be intracrines. In contrast, peptide or protein hormones, in general, act as endocrines, autocrines, or paracrines by binding to their receptors present on the cell surface. Several peptide/protein hormones or their isoforms also act inside the cell through different mechanisms. These peptide/protein hormones, which have intracellular functions, are also called intracrines. The term 'intracrine' is thought to have been coined to represent peptide/protein hormones that also have intracellular actions. To better understand intracrine, we can compare it to paracrine, autocrine and endocrine. The autocrine system deals with the autocrine receptors of a cell allowing for the hormones to bind, which have been secreted from that same cell. The paracrine system is one where nearby cells get hormones from a cell, and change the functioning of those nearby cells. The endocrine system refers to when the hormones from a cell affect another cell that is very distant from the one that released the hormone.
The prolactin receptor (PRLR) is a type I cytokine receptor encoded in humans by the PRLR gene on chromosome 5p13-14. It is the receptor for prolactin (PRL). The PRLR can also bind to and be activated by growth hormone (GH) and human placental lactogen (hPL). The PRLR is expressed in the mammary glands, pituitary gland, and other tissues. It plays an important role in lobuloalveolar development of the mammary glands during pregnancy and in lactation.
Marc Guy Albert Marie Lacroix is a Belgian biochemist and a researcher who specializes in breast cancer biology, metastasis and therapy.
Fibroblast growth factor receptor 1 (FGFR-1), also known as basic fibroblast growth factor receptor 1, fms-related tyrosine kinase-2 / Pfeiffer syndrome, and CD331, is a receptor tyrosine kinase whose ligands are specific members of the fibroblast growth factor family. FGFR-1 has been shown to be associated with Pfeiffer syndrome, and clonal eosinophilias.
Fibroblast growth factor receptor 3 (FGFR-3) is a protein that in humans is encoded by the FGFR3 gene. FGFR3 has also been designated as CD333. The gene, which is located on chromosome 4, location p16.3, is expressed in tissues such as the cartilage, brain, intestine, and kidneys.
G protein-coupled estrogen receptor 1 (GPER), also known as G protein-coupled receptor 30 (GPR30), is a protein that in humans is encoded by the GPER gene. GPER binds to and is activated by the female sex hormone estradiol and is responsible for some of the rapid effects that estradiol has on cells.
The estrogen receptor test (ERT) is a laboratory test to determine whether cancer cells have estrogen receptors. This information can guide treatment of the cancer.
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.
DirectHit is a pharmacodiagnostic test used to determine the tumor sensitivity or resistance to drug regimens recommended for the treatment of breast cancer by the National Comprehensive Cancer Network. It is a noninvasive test performed on small amounts of tissue removed during the original surgery lumpectomy, mastectomy, or core biopsy. DirectHit was developed by CCC Diagnostics Inc., a biotechnology company established by former researchers from Johns Hopkins University. DirectHit was launched on 14 January 2010. Currently, it is the only available test for predicting treatment outcomes for anticancer chemotherapy drugs for breast cancer.

A cancer biomarker refers to a substance or process that is indicative of the presence of cancer in the body. A biomarker may be a molecule secreted by a tumor or a specific response of the body to the presence of cancer. Genetic, epigenetic, proteomic, glycomic, and imaging biomarkers can be used for cancer diagnosis, prognosis, and epidemiology. Ideally, such biomarkers can be assayed in non-invasively collected biofluids like blood or serum.
