Clinical significance of CD166 and HER-2 in different types of gastric cancer.

Introduction: Cluster of differentiation 166 (CD166), a cancer stem cell (CSC) marker, and human epidermal growth factor receptor 2 (HER-2) are expressed in a diversity of malignancies and is associated with tumor progression. Although studies regarding the importance of CSC markers and HER-2 in gastric cancer (GC) have rapidly developed, their clinicopathological, prognosis, and diagnosis value still remain unsatisfying in GC. Therefore, the present study aims to investigate the clinical, prognostic, and diagnostic significance of CD166 and HER-2 in different histological types of GC.

Integrated genomic sequencing in myeloid blast crisis chronic myeloid leukemia (MBC-CML), identified potentially important findings in the context of leukemogenesis model.

Chronic myeloid leukemia (CML) is a model of leukemogenesis in which the exact molecular mechanisms underlying blast crisis still remained unexplored. The current study identified multiple common and rare important findings in myeloid blast crisis CML (MBC-CML) using integrated genomic sequencing, covering all classes of genes implicated in the leukemogenesis model. Integrated genomic sequencing via Whole Exome Sequencing (WES), Chromosome-seq and RNA-sequencing were conducted on the peripheral blood samples of three CML patients in the myeloid blast crisis.

The importance of CDC27 in cancer: molecular pathology and clinical aspects.

Background: CDC27 is one of the core components of Anaphase Promoting complex/cyclosome. The main role of this protein is defined at cellular division to control cell cycle transitions. Here we review the molecular aspects that may affect CDC27 regulation from cell cycle and mitosis to cancer pathogenesis and prognosis.

Genetic study of the PAH locus in the Iranian population: familial gene mutations and minihaplotypes.

Phenylketonuria (PKU), one of the most common inborn errors of amino acid metabolism, is caused by mutations in the phenylalanine hydroxylase (PAH) gene (PAH). PKU has wide allelic heterogeneity, and over 600 different disease-causing mutations in PAH have been detected to date. Up to now, there have been no reports on the minihaplotype (VNTR/STR) analysis of PAH locus in the Iranian population.

An Efficient Trio-Based Mini-Haplotyping Method for Genetic Diagnosis of Phenylketonuria.

Objective: The phenylalanine hydroxylase (PAH) locus has high linkage disequilibrium. Haplotypes related to this locus may thus be considered sufficiently informative for genetic diagnosis and carrier screening using multi-allelic markers. In this study, we present an efficient method for haplotype analysis of PAH locus using multiplexing dyes.

Comparable vitamin D3 metabolism in the endometrium of patients with recurrent spontaneous abortion and fertile controls.

Vitamin D exerts important roles during pregnancy, and its deficiency may be associated with several pregnancy complications, including pregnancy loss, yet no data are available for molecules involved in vitamin D metabolism in patients with unexplained recurrent spontaneous abortion. In this study, we investigated possible difference in endometrial expression of vitamin D3 receptor (VDR), 1α-hydroxylase (CYP27B1), and 24-hydroxylase (CYP24A1) in women with recurrent spontaneous abortion (n = 8) and healthy controls (n = 8). Gene expression of VDR, CYP27B1, and CYP24A1 was determined by real-time PCR, while VDR and CYP27B1 proteins were localized by immunohistochemistry and their abundance was validated by Western blot.

Effects of 1,25(OH)2 vitamin D3 on cytokine production by endometrial cells of women with recurrent spontaneous abortion.

Objective: To investigate immunomodulatory effect of 1,25(OH)2 vitamin D3 (1,25(OH)2D3) on cytokine production by endometrial cells of women with unexplained recurrent spontaneous abortion (URSA).

Design: In vitro study.

Setting: Academic research center.

Indoleamine 2,3-dioxygenase (IDO) is expressed at feto-placental unit throughout mouse gestation: An immunohistochemical study.

Introduction: The cells expressing Indoleamine 2, 3-dioxygenase (IDO) in feto-maternal interface mediate tryptophan catabolism, hence protect allogeneic fetus from lethal rejection by maternal immune responses. In this study, we report immuno-localization of IDO(+) cells in murine reproductive tract and placenta throughout mouse pregnancy by immunohistochemistry.

Materials And Methods: Syngeneic pregnant mice were examined for vaginal plug to discover about their state of pregnancy.
