FOXP3: A Player of Immunogenetic Architecture in Lung Cancer.

The transcription factor forkhead box protein 3 (FOXP3) is considered to be a prominent component of the immune system expressed in regulatory T cells (Tregs). Tregs are immunosuppressive cells that regulate immune homeostasis and self-tolerance. FOXP3 was originally thought to be a Tregs-specific molecule, but recent studies have pinpointed that FOXP3 is expressed in a diversity of benign tumors and carcinomas.

Identification of ATM-dependent long non-coding RNAs induced in response to DNA damage.

DNA damage response (DDR) is a complex process, essential for cell survival. Especially deleterious type of DNA damage are DNA double-strand breaks (DSB), which can lead to genomic instability and malignant transformation if not repaired correctly. The central player in DSB detection and repair is the ATM kinase which orchestrates the action of several downstream factors.

CRISPR/Cas9 screen for genome-wide interrogation of essential MYC-bound E-boxes in cancer cells.

The transcription factor MYC is a proto-oncogene with a well-documented essential role in the pathogenesis and maintenance of several types of cancer. MYC binds to specific E-box sequences in the genome to regulate gene expression in a cell-type- and developmental-stage-specific manner. To date, a combined analysis of essential MYC-bound E-boxes and their downstream target genes important for growth of different types of cancer is missing.

Genetic variants and risk of endocrine autoimmunity in relatives of patients with Addison's disease.

Since individuals with Addison's disease (AD) present considerable co-occurrence of additional autoimmune conditions, clustering of autoimmunity was also predicted among their relatives. The study was aimed to assess circulating autoantibodies in first-degree relatives of patients with AD and to correlate them with the established genetic risk factors (PTPN22 rs2476601, CTLA4 rs231775, and BACH2 rs3757247). Antibodies were evaluated using validated commercial assays, and genotyping was performed using TaqMan chemistry.

Is a Long Non-Coding RNA Necessary for CTCL Cell Growth.

Transmembrane protein 244 (TMEM244) was annotated to be a member of the TMEM family, which are is a component of cell membranes and is involved in many cellular processes. To date, the expression of the TMEM244 protein has not been experimentally confirmed, and its function has not been clarified. Recently, the expression of the gene was acknowledged to be a diagnostic marker for Sézary syndrome, a rare cutaneous T-cell lymphoma (CTCL).

Polymorphism in BACH2 gene is a marker of polyglandular autoimmunity.

Purpose: Genetically predisposed individuals may develop several autoimmune diseases-autoimmune polyendocrine syndromes (APS). APS types 2-4, are complex disorders, which combine various organ-specific autoimmune conditions. Recent reports support the considerable role of the BACH2 gene in immune cell differentiation and shifting the T-cell balance towards regulatory T-cells.

Overexpression of miR-7977 in CD4+ T cells is associated with multiplex autoimmunity in patients with Addison's disease.

Objective: Autoimmune Addison's disease (AD) results from a combination of the genetic predisposition, unclear environmental triggers and ensuing immune dysfunction. MicroRNA molecules (miRNAs) are involved in post-transcriptional regulation of numerous target genes, hence may affect the immune function and promote autoimmunity. A deregulated miRNAs profile was reported in several autoimmune conditions.

Hypoxia-Induced Regulates the Proliferation and Metastasis of Non-Small Cell Lung Cancer Cells.

Hypoxia in non-small cell lung cancer (NSCLC) affects cancer progression, metastasis and metabolism. We previously showed that FAM13A was induced by hypoxia in NSCLC but the biological function of this gene has not been fully elucidated. This study aimed to investigate the role of hypoxia-induced FAM13A in NSCLC progression and metastasis.

Upregulation of in New-Onset Type 1 Diabetes Mellitus.

Forkhead box O (FOXO) transcription factors have been implicated in the development and differentiation of the immune cells. FOXO3 plays a crucial role in physiologic and pathologic immune response. FOXO3, cooperatively with FOXO1, control the development and function of Foxp3 regulatory T cells (T).

Hypomethylation of the promoter region drives ectopic expression of TMEM244 in Sézary cells.

Sézary syndrome (SS) is an aggressive form of cutaneous T-cell lymphoma (CTCL) characterized by the presence of circulating malignant CD4+ T cells (Sézary cells) with many complex changes in the genome, transcriptome and epigenome. Epigenetic dysregulation seems to have an important role in the development and progression of SS as it was shown that SS cells are characterized by widespread changes in DNA methylation. In this study, we show that the transmembrane protein coding gene TMEM244 is ectopically expressed in all SS patients and SS-derived cell lines and, to a lower extent, in mycosis fungoides and in a fraction of T-cell lymphomas, but not in B-cell malignancies and mononuclear cells of healthy individuals.

sequence variant and elevated gene expression are associated with type 1 diabetes in Polish children.

Introduction: Type 1 diabetes (T1D) is caused by the autoimmune destruction of pancreatic β cells, resulting from coincident genetic predisposition and some environmental triggers. Signal transducer and activator of transcription 4 (STAT4) gene encodes a transcription factor, which promotes Th1 cell differentiation, interferon γ production, and development of Th17 cells. Polymorphisms of STAT4 are associated with several autoimmune conditions, while studies in T1D provided inconsistent results.

The most frequent Polish mutations are not susceptibility factors for tobacco-related cancers.

Introduction: The inactivation of both alleles of the gene leads to ataxia-telangiectasia syndrome, whereas carriers of monoallelic mutations in the gene are associated with increased risk of different types of cancer. Three substitutions in the gene (c.6095G>A, c.

Bioevaluation of superparamagnetic iron oxide nanoparticles (SPIONs) functionalized with dihexadecyl phosphate (DHP).

Superparamagnetic iron oxide nanoparticles (SPIONs) have been investigated for wide variety of applications. Their unique properties render them highly applicable as MRI contrast agents, in magnetic hyperthermia or targeted drug delivery. SPIONs surface properties affect a whole array of parameters such as: solubility, toxicity, stability, biodistribution etc.

miR-487a-3p upregulated in type 1 diabetes targets CTLA4 and FOXO3.

Aims: Type 1 diabetes (T1D) is an autoimmune disorder caused by the T-cell mediated destruction of the insulin-producing pancreatic beta cells. T1D is a consequence of complex processes, influenced by genetic, epigenetic and environmental factors. MicroRNAs (miRNAs) are small non-coding RNAs that target multiple mRNAs and regulate gene expression.

Genetic variants in ATM, H2AFX and MRE11 genes and susceptibility to breast cancer in the polish population.

Background: DNA damage repair is a complex process, which can trigger the development of cancer if disturbed. In this study, we hypothesize a role of variants in the ATM, H2AFX and MRE11 genes in determining breast cancer (BC) susceptibility.

Methods: We examined the whole sequence of the ATM kinase domain and estimated the frequency of founder mutations in the ATM gene (c.

Elevated serum RANTES chemokine levels in autoimmune Addison disease.

INTRODUCTION    Regulated on activation, normal T‑cell expressed and secreted chemokine (RANTES), the product of the CCL5 gene, is involved in trafficking immune cells into the inflammation site. It acts as coactivator of T cells and promotes polarization of the immune response towards the Th1 profile. In autoimmune Addison disease (AAD), the adrenal cortex is gradually destroyed by adrenal‑specific immune cell infiltration.

FKBP5 polymorphism is associated with insulin resistance in children and adolescents with obesity.

Objective: Since metabolic syndrome shares several clinical features with hypercortisolism, it was hypothesised that genes altering individual glucocorticoid (GC) sensitivity might be implicated in pathogenesis of obesity and its adverse outcomes. FKBP5 gene encodes a chaperon protein in the GC receptor (GR) complex, which modulates steroid action upon target genes. Its functional variant, rs1360780, may enhance FKBP5 gene transcription, affect GR signalling and thereby influence the hypothalamo-pituitary-adrenal axis.

MAVS is not a Likely Susceptibility Locus for Addison's Disease and Type 1 Diabetes.

Mitochondrial antiviral signaling (MAVS) protein is an intracellular adaptor molecule, downstream of viral sensors, retinoid acid-inducible gene I (RIG-I)-like receptors (RLRs). Impaired antiviral cell signaling might contribute to autoimmunity. Studies have recently shown variations in genes encoding RLRs as risk factors for autoimmune diseases.

Positive autoantibodies to ZnT8 indicate elevated risk for additional autoimmune conditions in patients with Addison's disease.

Autoimmune Addison's disease (AAD) associates with exceptional susceptibility to develop other autoimmune conditions, including type 1 diabetes (T1D), marked by positive serum autoantibodies to insulin (IAA), glutamic acid decarboxylase (GADA) and insulinoma-associated protein 2 (IA-2A). Zinc transporter 8 (ZnT8) is a new T1D autoantigen, encoded by the SLC30A8 gene. Its polymorphic variant rs13266634C/T seems associated with the occurrence of serum ZnT8 antibodies (ZnT8A).

Polymorphisms of the Toll-Like Receptor-3 Gene in Autoimmune Adrenal Failure and Type 1 Diabetes in Polish Patients.

Infectious agents are plausible environmental triggers for autoimmunity in genetically susceptible individuals. Polymorphic variants of genes implicated in innate immunity may affect immune responses and hence promote auto-aggressive reactions. Genes such as Toll-like receptor-3 (TLR3), which participate in recognizing conserved foreign molecules and mounting the first line of defence against viral infections, are promising functional candidates in autoimmune conditions.

Susceptibility loci in lung cancer and COPD: association of IREB2 and FAM13A with pulmonary diseases.

Genome-wide association studies have identified loci at 15q25 (IREB2) and 4q22 (FAM13A), associated with lung cancer (LC) and chronic obstructive pulmonary disease (COPD). The aim of our research was to determine the association of IREB2 and FAM13A SNPs with LC and severe/very severe COPD patients. We examined IREB2 variants (rs2568494, rs2656069, rs10851906, rs13180) and FAM13A (rs1903003, rs7671167, rs2869967) among 1.

Cumulative effect of IFIH1 variants and increased gene expression associated with type 1 diabetes.

Aims: IFIH1 (Interferon Induced with Helicase C domain 1) gene encodes a sensor of double-stranded RNA, which initiates antiviral activity. Recent studies have indicated the association of rare and common IFIH1 variants with type 1 diabetes mellitus (T1D). The aim of this study was to investigate whether polymorphisms in the IFIH1 locus are a risk factor for T1D in Caucasian patients from Poland.

Interleukin-2 and subunit alpha of its soluble receptor in autoimmune Addison's disease--an association study and expression analysis.

Autoimmune Addison's disease (AAD) results from T cell-mediated destruction of the adrenal cortex, commonly accompanied by autoantibodies to 21-hydroxylase (21OH). In order to gain insight into the obscure aetiology of this disease, we investigated the roles of the IL2 and IL2RA genes, encoding interleukin-2 and subunit alpha of its receptor (IL2Ra), respectively. The association of AAD with IL2 and IL2RA polymorphisms (rs6822844, rs2069762, rs3136534, rs11594656, rs3118470 and rs2104286) was tested in 223 patients and 672 healthy controls.
