Somatic mutations reveal asymmetric cellular dynamics in the early human embryo.
(NATURE PUBLISHING GROUP, 2017-03-30)Somatic cells acquire mutations throughout the course of an individual's life. Mutations occurring early in embryogenesis are often present in a substantial proportion of, but not all, cells in postnatal humans and thus ... -
Somatic PIK3CA Mutations in Sporadic Cerebral Cavernous Malformations.
(MASSACHUSETTS MEDICAL SOC, 2021-09-09)BACKGROUND: Cerebral cavernous malformations (CCMs) are common sporadic and inherited vascular malformations of the central nervous system. Although familial CCMs are linked to loss-of-function mutations in KRIT1 (CCM1), ... -
Sorafenib dose escalation in treatment-naïve patients with metastatic renal cell carcinoma: a non-randomised, open-label, Phase 2b study.
(2017-06)Objective To assess the efficacy and safety of sorafenib dose escalation in metastatic renal cell carcinoma (mRCC).Patients and methods Intra-patient dose escalation may enhance the clinical benefit of targeted anticancer ... -
Sorafenib in combination with transarterial chemoembolisation in patients with unresectable hepatocellular carcinoma (TACE 2): a randomised placebo-controlled, double-blind, phase 3 trial.
(2017-08)Background Transarterial chemoembolisation (TACE) is the standard of care for patients with intermediate stage hepatocellular carcinoma, while the multikinase inhibitor sorafenib improves survival in patients with advanced ... -
Sotrovimab restores neutralization against current Omicron subvariants in patients with blood cancer.
(CELL PRESS, 2023-05-08)Wu et al. report that patients with hematologic malignancies have reduced immunity against SARS-CoV-2 Omicron subvariants and Sotrovimab retains neutralizing capacity against all tested Omicron subvariants. -
SOX11 promotes epithelial/mesenchymal hybrid state and alters tropism of invasive breast cancer cells.
(eLife Sciences Publications, Ltd, 2020-09-10)SOX11 is an embryonic mammary epithelial marker that is normally silenced prior to birth. High SOX11 levels in breast tumours are significantly associated with distant metastasis and poor outcome in breast cancer patients. ... -
SOX11 promotes invasive growth and ductal carcinoma in situ progression.
(WILEY, 2017-10-01)Here, we show that SOX11, an embryonic mammary marker that is normally silent in postnatal breast cells, is expressed in many oestrogen receptor-negative preinvasive ductal carcinoma in situ (DCIS) lesions. Mature mammary ... -
Sox11 regulates mammary tumour-initiating and metastatic capacity in Brca1-deficient mouse mammary tumour cells.
(COMPANY BIOLOGISTS LTD, 2021-05-01)Little is known about the role of Sox11 in the regulation of mammary progenitor cells. Sox11 is expressed by mammary bud epithelial cells during embryonic mammary gland development and is not detected in mammary epithelial ... -
SOX9 is a driver of aggressive prostate cancer by promoting invasion, cell fate and cytoskeleton alterations and epithelial to mesenchymal transition.
(Impact Journals, LLC, 2018-01-26)Aggressive lethal prostate cancer is characterised by tumour invasion, metastasis and androgen resistance. Understanding the mechanisms by which localised disease progresses to advanced lethal stages is key to the development ... -
Sox9 regulates cell state and activity of embryonic mouse mammary progenitor cells.
(2018-01)Embryonic mammary cells are a unique population comprised of undifferentiated, highly plastic progenitor cells that create normal mammary tissues. The mammary gland continues to develop after birth from descendants of ... -
Sox9 regulates cell state and activity of embryonic mouse mammary progenitor cells.
(NATURE PUBLISHING GROUP, 2018-12-13)Embryonic mammary cells are a unique population comprised of undifferentiated, highly plastic progenitor cells that create normal mammary tissues. The mammary gland continues to develop after birth from descendants of ... -
Sp1 phosphorylation by ATM downregulates BER and promotes cell elimination in response to persistent DNA damage.
(OXFORD UNIV PRESS, 2018-02-28)ATM (ataxia-telangiectasia mutated) is a central molecule for DNA quality control. Its activation by DNA damage promotes cell-cycle delay, which facilitates DNA repair prior to replication. On the other hand, persistent ... -
Spatial analyses of immune cell infiltration in cancer: current methods and future directions: A report of the International Immuno-Oncology Biomarker Working Group on Breast Cancer.
(WILEY, 2023-08-01)Modern histologic imaging platforms coupled with machine learning methods have provided new opportunities to map the spatial distribution of immune cells in the tumor microenvironment. However, there exists no standardized ... -
Spatial Architecture of Myeloid and T Cells Orchestrates Immune Evasion and Clinical Outcome in Lung Cancer.
(AMER ASSOC CANCER RESEARCH, 2024-06-03)UNLABELLED: Understanding the role of the tumor microenvironment (TME) in lung cancer is critical to improving patient outcomes. We identified four histology-independent archetype TMEs in treatment-naïve early-stage lung ... -
Spatial interplay of lymphocytes and fibroblasts in estrogen receptor-positive HER2-negative breast cancer.
(NATURE PORTFOLIO, 2022-04-28)In estrogen-receptor-positive, HER2-negative (ER+HER2-) breast cancer, higher levels of tumor infiltrating lymphocytes (TILs) are often associated with a poor prognosis and this phenomenon is still poorly understood. ... -
Spatial interrogation of tumour microenvironment using artificial intelligence
(Institute of Cancer Research (University Of London), 2023-03-06)The tumour microenvironment can provide critical information for disease diagnosis, treatment planning, and prognosis. However, the complexity of its morphological, cellular, and spatial architecture hinders accurate ... -
Spatial localisation of Discoidin Domain Receptor 2 (DDR2) signalling is dependent on its collagen binding and kinase activity.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018-06-18)Discoidin Domain Receptor 2 (DDR2) is a collagen-binding receptor tyrosine kinase that initiates delayed and sustained tyrosine phosphorylation signalling. To understand the molecular basis of this unique phosphorylation ... -
Spatial patterns of tumour growth impact clonal diversification in a computational model and the TRACERx Renal study.
(NATURE PORTFOLIO, 2022-01-01)Genetic intra-tumour heterogeneity fuels clonal evolution, but our understanding of clinically relevant clonal dynamics remain limited. We investigated spatial and temporal features of clonal diversification in clear cell ... -
Spatial Phenotyping of Tumour Immune Microenvironment in the Non-small Cell Lung Cancer Using Artificial Intelligence
(Institute of Cancer Research (University Of London), 2024-02-26)Lung cancer is the second most common cancer type worldwide, with a five-year survival rate of about 20%. The aggressiveness of the disease and the inefficiency of treatment are partially attributed to the intra-tumour ... -
