MiR-346 is an Androgen Receptor (AR)-activating miR that associates with DNA damage response (DDR)-linked transcripts in prostate cancer (PC). MiR-346 induces rapid and extensive DNA damage in PC cells through chromatin association, activation of transcription, R-loop formation and DNA replication stress, leading to checkpoint activation and cell cycle arrest. MiR-346 interacts with lncRNA, NORAD, in PC cells, which functions to maintain mitosis, DDR, and chromosomal integrity...

Objective: The Fas/Fas ligand (FasL) apoptotic pathway is activated in patients with autoimmune thyroid disease (AITD). It is believed that Fas and FasL expression in intrathyroidal T lymphocytes and thyrocytes is regulated in a manner resulting in thyroid cell apoptosis in Hashimoto’s thyroiditis (HT) or lymphocyte apoptosis in Graves’ disease (GD). The hypothesis that Fas and FasL may be differentially expressed on peripheral lymphocytes in patients with HT and GD ...

Introduction-objective: Fas-mediated thyroid cell apoptosis is differentially regulated in autoimmune thyroid disease (AITD) being up-regulated in Hashimoto’s thyroiditis (HT) and down-regulated in Graves’ disease (GD). The soluble form of Fas (sFas), lacking the transmembrane domain due to alternative splicing may inhibit apoptosis by binding to Fas ligand. In this preliminary study we examined whether sFas is also differentially expressed in patients with AITD....

Background: Temple syndrome (TS) is a disorder caused by dysregulation of imprinted genes at chromosome 14q32. It is important to distinguish the growth pattern from other imprinting disorders such as Russell–Silver and Prader–Willi syndromes.Aims: To describe the growth pattern in TS.Methods: 51 cases were identified from 11 countries. Height, weight, birth weight and head circumference were converted to SDS using countr...

Objectives: Patients with thyroid dysfunction due to AITD have been found to have increased oxidative stress. Possible associations of oxidative stress with thyroid hormone (TH) and thyroid autoantibodies (ThAb) levels in euthyroid patients with autoimmune thyroiditis have not been adequately studied. We examined possible associations of oxidative stress markers with TH levels and with the presence of ThAb in euthyroid women with Hashimoto’s thyroiditis (with or without T...

Introduction: In the literature there are only three papers so far, addressing the impact of thyroid antibodies (Anti-TPO) on pregnancy in Type1 Diabetic Women (DM1) and these present conflicting results. The aim of the study is to evaluate the presence of Anti-TPO in DM1 pregnant women and whether these are related with differences in thyroid function, metabolic control and pregnancy outcome.Methods: In 78 DM1 women with singleton pregnancies Anti-TPO, ...

BackgroundRecent knowledge implicates a differential expression of the insulin-like growth factor-1 (IGF-1) mRNA splice variants (i.e., IGF-1Ea, IGF-1Eb and IGF-1Ec) in cancerous tissues, implying possible specific roles of the encoded IGF-1 protein isoforms in cancer biology. In particular, there is growing evidence that IGF-1Ec isoform may plays a distinct biological role in various types of cancer. The aim of the present study was to investigate wheth...

Background and Aims: Our objective was to assess the association between genetic polymorphisms in TCF7L2, CTRB1/2 and GLP-1R genes and inter-individual variability in response to treatment with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in terms of glycemic control and weight loss among Greek individuals with type 2 diabetes mellitus (T2DM) and to identify potential predictors of response to GLP-1 RA therapy.Material...

Introduction: Insulin-like growth factor-I (IGF-I) has a role in cell proliferation, differentiation, migration, and survival. By alternative splicing different IGF-I mRNA transcripts as IGF-IEc (mechano growth factor, MGF) or IGF-IEa variants are produced. MGF induces muscle hypertrophy and implicated in the pathophysiology of various types of cancer. Aim of the study was to investigate the role of MGF in the pathophysiology of neuroendocrine neoplasms (NENs).<p class="ab...

Introduction: Polymorphisms of the receptor for advanced glycation end products (AGEs), RAGE, have been associated with autoimmune disorders and their complications. There are no studies concerning Hashimoto’s thyroiditis (HT); the aim of our study was to investigate the possible role of two RAGE polymorphisms (−429T>C, −374T>A) in combination with indices of oxidative status in women with HT.Design: We examined 300 euth...
