Common Cytochrome P4503a (Cyp3a4 And Cyp3a5) And Thiopurine S-Methyl Transferase (Tpmt) Polymorphisms In Turkish Population, Müge Aydin Sayi̇toğlu, İnci̇ Yildiz, Özden Hatirnaz, Uğur Özbek

Turkish Journal of Medical Sciences

Polymorphisms in the genes encoding cytochrome p450 (CYP) and thiopurine S-methyl transferase (TPMT) enzymes catalyze the metabolic reactions of several drugs. These polymorphisms might be responsible for adverse drug reactions. Turkish population data for these genes still needs to be elucidated. We aimed to detect the allele frequencies of thiopurine S-methyl transferase (TPMT), cytochrome p4503A4*1B (CYP3A4*1B) and cytochrome p4503A4*3 (CYP3A5*3) gene variants in the Turkish population. We examined the TPMT (*1, *2, *3A, *3C), CYP3A4*1B and CYP3A5*3 variant allele frequencies in a group of healthy Turkish Caucasian blood donors by using PCR-RFLP, allele-specific PCR and direct sequencing techniques. The frequencies …

Turkish Journal of Medical Sciences

The encapsulated follicular variant of papillary thyroid carcinoma constitutes the most common source of consultation material in thyroid pathology. We present our five consecutive cases to illustrate this issue. The diagnosis of the encapsulated follicular variant of papillary thyroid carcinoma is considerably controversial. These tumors are encapsulated neoplasms and have the nuclear features of papillary thyroid carcinoma. Although the criteria were described for the diagnosis, a considerable subjectivity is present among the pathologists. Therefore, the categories of "well differentiated carcinoma" and "well differentiated tumor of uncertain malignant potential" were included in the diagnostic spectrum of these neoplasms. Five consecutive cases …

Innate Antiviral Response Targets Hiv-1 Release By The Induction Of Ubiquitin-Like Protein Isg15, Atsushi Okumura, Gengshi Lu, Ian Pitha-Rowe, Paula M. Pitha

Dartmouth Scholarship

The goal of this study was to elucidate the molecular mechanism by which type I IFN inhibits assembly and release of HIV-1 virions. Our study revealed that the IFN-induced ubiquitin-like protein ISG15 mimics the IFN effect and inhibits release of HIV-1 virions without having any effect on the synthesis of HIV-1 proteins in the cells. ISG15 expression specifically inhibited ubiquitination of Gag and Tsg101 and disrupted the interaction of the Gag L domain with Tsg101, but conjugation of ISG15 to Gag or Tsg101 was not detected. The inhibition of Gag-Tsg101 interaction was also detected in HIV-1 infected, IFN-treated cells. Elimination …

Smc3 Knockdown Triggers Genomic Instability And P53-Dependent Apoptosis In Human And Zebrafish Cells., Giancarlo Ghiselli Jan 2006

Smc3 Knockdown Triggers Genomic Instability And P53-Dependent Apoptosis In Human And Zebrafish Cells., Giancarlo Ghiselli

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: The structural maintenance of chromosome 3 (SMC3) protein is a constituent of a number of nuclear multimeric protein complexes that are involved in DNA recombination and repair in addition to chromosomal segregation. Overexpression of SMC3 activates a tumorigenic cascade through which mammalian cells acquire a transformed phenotype. This has led us to examine in depth how SMC3 level affects cell growth and genomic stability. In this paper the effect of SMC3 knockdown has been investigated. RESULTS: Mammalian cells that are SMC3 deficient fail to expand in a clonal population. In order to shed light on the underlying mechanism, experiments …

INTRODUCTION: Predicting the clinical course of breast cancer is often difficult because it is a diverse disease comprised of many biological subtypes. Gene expression profiling by microarray analysis has identified breast cancer signatures that are important for prognosis and treatment. In the current article, we use microarray analysis and a real-time quantitative reverse-transcription (qRT)-PCR assay to risk-stratify breast cancers based on biological 'intrinsic' subtypes and proliferation. METHODS: Gene sets were selected from microarray data to assess proliferation and to classify breast cancers into four different molecular subtypes, designated Luminal, Normal-like, HER2+/ER-, and Basal-like. One-hundred and twenty-three breast samples (117 invasive …

No Vaccine Against Hiv Yet--Are We Not Perfectly Equipped?, Mahender Singh Jan 2006

No Vaccine Against Hiv Yet--Are We Not Perfectly Equipped?, Mahender Singh

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Enormous effort has been devoted to the development of a vaccine against human immunodeficiency virus (HIV). But it is proving to be an unprecedented challenge to create an effective vaccine mainly due to the high genetic variability of the virus and the necessity of cytotoxic T lymphocytes (CTL) for containing the infection. Currently pursued vaccine strategies appear to induce CTL in nonhuman primate models but in the early clinical trials, these strategies fail to fully control the viral infection. New strategies that can cover the vast genetic diversity of HIV are needed for the development of a potent vaccine.

All Dugoni School of Dentistry Faculty Articles

Porphyromonas gingivalis, an important periodontal pathogen, is an effective colonizer of oral tissues. The organism successfully invades, multiplies in, and survives for extended periods in primary gingival epithelial cells (GECs). It is unknown whether P. gingivalis resides in the cytoplasm of infected cells throughout the infection or can spread to adjacent cells over time. We developed a technique based on flow cytofluorometry and fluorescence microscopy to study propagation of the organism at different stages of infection of GECs. Results showed that P. gingivalis spreads cell to cell and that the amount of spreading increases gradually over time. There was a …

Jay Reddy Publications

FoxP3 is a lineage specific marker for regulatory T-cells (Treg). We have generated FoxP3 knock-in (KI) mice by introducing a bicistronic GFP reporter into the endogenous FoxP3 locus, allowing us to faithfully track T-reg in vivo. Recently, we have also generated a MOG 35-55/IAb-tetramer. The combination of these two technologies enables us to study the in vivo behavior of myelin specific T-reg and effector T-cells (T-eff) during EAE. Upon immunization with MOG 35-55, we identified a population of MOG-tetramerreactive T-reg in the peripheral lymphoid compartment. T-reg trafficked to the CNS where they were readily detected as early as day 10 …

T-cell immunoglobulin and mucin (TIM) family Members are differentially expressed on Th1 and Th2 cells. Polymorphisms of TIM-1 have been associated with susceptibility to asthma; however, its role in regulating autoimmunity has not been studied. Here, we have used an agonistic antiTIM-1 antibody (Ab, Clone 3B3) which has previously been shown to costimulate T-cell activation and expansion, to analyze the role of TIM-1 in the development and regulation of experimental autoimmune encephalomyelitis (EAE). Treatment with 3B3 dramatically enhances the severity of EAE as well as the frequency of encephalitogenic CD4+ T-cells and the production of IFN-g and IL-17 by these …

Tannerella Forsythia, A Periodontal Pathogen Entering The Genomic Era, Anne C. R. Tanner, Jacques Izard Jan 2006

Tannerella Forsythia, A Periodontal Pathogen Entering The Genomic Era, Anne C. R. Tanner, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Several questions need to be addressed to evaluate whether Tannerella forsythia is to be considered a periodontal pathogen. T. forsythia has been detected in periodontal health and disease, so could it be a pathogen? The species was not detected in many studies despite finding other putative pathogens, so could it be important in pathogenicity? The challenges of working with T. forsythia include its fastidious and anaerobic growth requirements for cultural detection. Thus, studies associating T. forsythia with periodontal and other oral infections have used noncultural approaches (immunoassays and DNA-based assays) in addition to cultural approaches. We feel …

Communicating Hydrocephalus In Systemic Lupus Erythematosus, Ramazan Albayrak, Sai̇t Albayram, Hakan Selçuk, Sebahatti̇n Sai̇p, Hali̇t Yilmaz, Ci̇van Işlak

Turkish Journal of Medical Sciences

Central nervous system (CNS) involvement has been recognized as the second leading cause of death in patients with systemic lupus erythematosus (SLE), although hydrocephalus is seen very rarely. We report a case of communicating hydrocephalus in a 24-year-old woman having previously diagnosed SLE without antiphospholipid antibody syndrome or cerebral venous angiographic abnormality. We propose direct damage-thrombosis of small sized venous structures or immune complex deposition within arachnoid villi, which impair cerebrospinal fluid flow, as a possible, yet unproven, pathophysiologic mechanism for hydrocephalus in SLE.

Modulation Of Cell Signaling By Tomoregulins In Embryogenesis And Cancer, Paul William Harms Jan 2006

Modulation Of Cell Signaling By Tomoregulins In Embryogenesis And Cancer, Paul William Harms

All ETDs from UAB

Growth factor signals often regulate similar cellular processes both during embryogenesis and in adult homeostasis. Stringent control of these signals ensures proper embryonic development and correct cell physiology in mature individuals. Recently, a family of two members of Tomoregulin (or transmembrane protein with epidermal growth factor-like and two follistatin domains [TMEFF]) was found to interact with transforming growth factor-β (TGF-β) and ErbB signaling pathways, both of which are implicated in development and in cancer biology in the adult. The function as well as the mechanisms of TMEFFs in modulating these two signals has not been elucidated in detail. In this …

Increased Hexosamine Biosynthesis And Protein O-Glcnac Protect Isolated Rat Heart From Ischemia/Reperfusion Injury, Jia Liu

All ETDs from UAB

Increased levels of protein-associated O-linked N-acetylglucosamine (O-GlcNAc) have been correlated with increased tolerance to stress. Therefore the goal of this study was to determine whether enhanced flux through the hexosamine biosynthesis pathway (HBP), which leads to elevated levels of O-GlcNAc, increased the tolerance of the heart to ischemia and reperfusion (I/R). Hearts from male rats were isolated and perfused with Krebs-Henseliet buffer containing 5mM glucose, and global, no-flow ischemia was induced for 20min followed by 60 min reperfusion. 20 min pre-treatment with 10 mM glucosamine, which enters the HBP directly, significantly improved functional recovery and decreased cardiac Troponin I release …
