Loss of 5'-Methylthioadenosine Phosphorylase (MTAP) is Frequent in High-Grade Gliomas; Nevertheless, it is Not Associated with Higher Tumor Aggressiveness.
(MDPI, 2020-02-20)The 5'-methylthioadenosine phosphorylase (MTAP) gene is located in the chromosomal region 9p21. MTAP deletion is a frequent event in a wide variety of human cancers; however, its biological role in tumorigenesis remains ... -
Loss of Bardet-Biedl syndrome proteins causes synaptic aberrations in principal neurons.
(PUBLIC LIBRARY SCIENCE, 2019-09-01)Bardet-Biedl syndrome (BBS), a ciliopathy, is a rare genetic condition characterised by retinal degeneration, obesity, kidney failure, and cognitive impairment. In spite of progress made in our general understanding of BBS ... -
Loss of E-cadherin leads to Id2-dependent inhibition of cell cycle progression in metastatic lobular breast cancer.
(SPRINGERNATURE, 2022-05-20)Invasive lobular breast carcinoma (ILC) is characterized by proliferative indolence and long-term latency relapses. This study aimed to identify how disseminating ILC cells control the balance between quiescence and cell ... -
Loss of heterozygosity as a marker of homologous repair deficiency in multiple myeloma: a role for PARP inhibition?
(NATURE PUBLISHING GROUP, 2018-07-01)PARP inhibitors can induce synthetic lethality in tumors characterized by homologous recombination deficiency (HRD), which can be detected by evaluating genome-wide loss of heterozygosity (LOH). Multiple myeloma (MM) is a ... -
Loss of INPP4B causes a DNA repair defect through loss of BRCA1, ATM and ATR and can be targeted with PARP inhibitor treatment.
(IMPACT JOURNALS LLC, 2015-04-30)Treatment options for ovarian cancer patients remain limited and overall survival is less than 50% despite recent clinical advances. The lipid phosphatase inositol polyphosphate 4-phosphatase type II (INPP4B) has been ... -
Loss of MMP-8 in ductal carcinoma in situ ( DCIS)-associated myoepithelial cells contributes to tumour promotion through altered adhesive and proteolytic function
(2017-01-01)Background: Normal myoepithelial cells (MECs) play an important tumour-suppressor role in the breast but display an altered phenotype in ductal carcinoma in situ (DCIS), gaining tumour-promoter functions. Matrix ... -
Loss of P16(INK4a) results in increased glucocorticoid receptor activity during fibrosarcoma development
(NATL ACAD SCIENCES, 2003-03-18)‘Glucocorticoids inhibit proliferation of many cell types, but the relationship between the glucocorticoid receptor (GR) and the proteins regulating cell cycle progression is not fully understood. We previously found that ... -
Love laughs at Locksmiths: Ubiquitylation of p62 unlocks its autophagy receptor potential.
(INST BIOCHEMISTRY & CELL BIOLOGY, 2017-05-01)The multimodular adapter p62/sequestosome-1 plays prominent roles in physiology and disease by mediating cell signaling and cargo degradation. The work by Peng et al. published recently in Cell Research provides mechanistic ... -
Low expression of hexokinase-2 is associated with false-negative FDG-positron emission tomography in multiple myeloma.
(AMER SOC HEMATOLOGY, 2017-07-06)18F-Fluorodeoxyglucose (FDG)-positron emission tomography (PET) and diffusion-weighted magnetic resonance imaging with background signal suppression (DWIBS) are 2 powerful functional imaging modalities in the evaluation ... -
Low Incidence of Corticosteroid-associated Adverse Events on Long-term Exposure to Low-dose Prednisone Given with Abiraterone Acetate to Patients with Metastatic Castration-resistant Prostate Cancer.
(ELSEVIER SCIENCE BV, 2016-09-01)BACKGROUND: Abiraterone acetate (AA) is the prodrug of abiraterone, which inhibits CYP17A1 and testosterone synthesis and prolongs the survival of patients with metastatic castration-resistant prostate cancer (mCRPC). AA ... -
Low-contact and high-interconnectivity pathology (LC&HI Path): post-COVID19-pandemic practice of pathology.
(WILEY, 2020-10-01)The COVID-19 pandemic situation may be viewed as an opportunity to accelerate some of the ongoing transformations in modern pathology. This refers primarily to the digitalisation of the practice of tissue and cellular ... -
Low-cost Kinect Version 2 imaging system for breath hold monitoring and gating: Proof of concept study for breast cancer VMAT radiotherapy.
(WILEY, 2018-05-01)Voluntary inspiration breath hold (VIBH) for left breast cancer patients has been shown to be a safe and effective method of reducing radiation dose to the heart. Currently, VIBH protocol compliance is monitored visually. ... -
Low-grade serous ovarian cancer: expert consensus report on the state of the science.
(BMJ PUBLISHING GROUP, 2023-09-04)Compared with high-grade serous carcinoma, low-grade serous carcinoma of the ovary or peritoneum is a less frequent epithelial ovarian cancer type that is poorly sensitive to chemotherapy and affects younger women, many ... -
Low-risk Prostate Cancer: Identification, Management, and Outcomes.
(2017-08)Context The incidence of low-risk prostate cancer (PCa) has increased as a consequence of prostate-specific antigen testing.Objective In this collaborative review article, we examine recent literature regarding low-risk ... -
LUBAC determines chemotherapy resistance in squamous cell lung cancer.
(ROCKEFELLER UNIV PRESS, 2019-02-04)Lung squamous cell carcinoma (LSCC) and adenocarcinoma (LADC) are the most common lung cancer subtypes. Molecular targeted treatments have improved LADC patient survival but are largely ineffective in LSCC. The tumor ... -
LUME-Meso: Design and Rationale of the Phase III Part of a Placebo-Controlled Study of Nintedanib and Pemetrexed/Cisplatin Followed by Maintenance Nintedanib in Patients With Unresectable Malignant Pleural Mesothelioma.
