Organ transplant recipients (OTRs) are at increased risk of cutaneous malignancy. Skin disorders in OTRs of color (OTRoC) have rarely been systematically assessed. We aimed to ascertain the burden of skin disease encountered in OTRoC by prospectively collecting data from OTRs attending two post-transplant skin surveillance clinics: one in London, UK and one in Philadelphia, USA. Retrospective review of all dermatological diagnoses was performed. Data from 1766 OTRs were analysed: 1024 (58%) white, 376 (21%) black, 261 (15%) Asian, 57 (3%) Middle Eastern/Mediterranean (ME/M), 48 (2...

STAT3 is attractive target for development of anti-cancer therapeutics as it is implicated in nearly all forms of human tumors. To identify novel leads, we screened a combinatorial peptide library displayed on the surface of M13 bacteriophage. After three rounds of biopanning, a dodecapeptide with the YYVSWPPDMMHY sequence was found to be enriched by 36 % while another with a short consensus motif was displayed in 20% of the phages. Binding analysis by isothermal titration calorimetry shows the most displayed peptide interacted with a Kd of 1...

Loss of chromosome Y (LOY) is a mosaic aneuploidy that can be detected mainly in blood samples of male individuals. Usually, LOY occurrence increases with chronological age in healthy men. Moreover, recently LOY has been reported in association with several diseases, such as cancer, where its frequency is even higher. The Y chromosome is one of the shortest chromosomes of the human karyotype, and it is crucial for correct male development. This chromosome has functions beyond the male reproductive system, and loss of its genes or even LOY can have consequences for the male body that are yet to be elucidated...

Bone is one of the most frequent metastatic sites in non-small cell lung cancer (NSCLC). Osimertinib, with and without bevacizumab (BV), has been investigated on advanced NSCLC patients. However, the efficacy of those drugs on bone metastasis of NSCLC has not been investigated. The human NSCLC cell line H1975, expressing red fluorescent protein (H1975-RFP), was orthotopically injected to the tibia of nude mice. The established mouse models were randomized into four treatment groups of nine mice: Control; BV alone; osimertinib alone; osimertinib and BV combination...

INTRODUCTION: There are reports that lung cancer in non-smokers (LCINS) is increasing in the United Kingdom (UK) and other high-income countries but evidence from large-scale cohort studies to support this claim is limited. MATERIAL AND METHODS: Using The Health Improvement Network (THIN) IQVIA™ Medical Research Data, we identified a cohort of 3,679,831 people from the UK self-reporting to their primary care physician as never or non-smokers. We estimated age-adjusted incidence rates for recorded lung cancer before (1998-2007) and after (2008-2018) the introduction of smoke-free legislation using multivariable Poisson regression...

BACKGROUND: Interleukin 7 receptor (IL-7R) is a member of the type I cytokine receptor family, which affects the occurrence of various tumors by forming a signaling complex with its ligand Interleukin 7 (IL-7). This study aimed to explore the potential relationships of IL-7R polymorphisms with breast cancer susceptibility in the Chinese Han women. METHODS: Five polymorphisms of IL-7R gene (rs969129, rs10213865, rs10053847, rs118137916, and rs6451231) form 553 patients and 550 healthy individuals among the Chinese Han women were genotyped using Agena MassARRAY platform...

BACKGROUND: Carnosic acid (CA) is one of the main constituents in rosemary extract. It possesses valuable pharmacological properties, including anti-oxidant, anti-inflammatory, anti-microbial and anti-cancer activities. Numerous in vitro and in vivo studies investigated the anticancer profile of CA and emphasized its potentiality for cancer treatment. Nevertheless, the role of multidrug-resistance (MDR) related mechanisms for CA's anticancer effect is not yet known. PURPOSE: We investigated the cytotoxicity of CA against known mechanisms of anticancer drug resistance (P-gp, ABCB5, BCRP, EGFR and p53) and determined novel putative molecular factors associated with cellular response towards CA...

INTRODUCTION: The treatment of advanced stage laryngeal suffered a major shift away from surgery and towards larynx-preservation alternatives after the publication of major clinical trials. But its applicability in real-world situations is not consensual. MATERIALS AND METHODS: We reviewed a population-based database from Brazil regarding patients treated for laryngeal cancer and selected those with stage IV disease at presentation. Survival analysis was realized by the Cox proportional hazards method and propensity scores were used to compensate for non-random allocation to different treatment arms...

Genome-wide association studies have established that human REL is a susceptibility gene for lymphoid cancers and inflammatory diseases. REL is the hematopoietic member of the nuclear factor-κB (NF-κB) family and is frequently amplified in human lymphomas. However, the mechanism through which REL and its encoded protein c-Rel affect human lymphoma is largely unknown. Using both loss-of-function and gain-of-function approaches, we studied the roles of REL gene in human Jurkat leukemia cells. Compared with control Jurkat cells, REL knockout cells exhibited significant defects in cell growth and mitochondrial respiration...
