Introduction: Glucocroticoids (GCs) which are routinely used in the treatment of Acute Lymphocytic Leukemia (ALL), found recently to be beneficial in a subset of AML patients resistant to chemotherapy, by promoting leukemia cells apoptosis. Current studies indicate that vitamin D (VitD) deficiency is highly prevalent among AML patients, posing vitamin D as a therapeutic supplementation. Our previous study demonstrated that VitD exerts inhibitory effect on Dexamethasone-induced...

Background/Aims: Post-operative hypoparathyroidism still remains a significant complication after thyroidectomy. Intraoperative imaging modalities, such as near infrared fluorescence by the use of indocyanine green (ICG), may assist to identify and preserve the parathyroid glands (PGs). The purpose of this study was to test the association between intra-operative ICG staining scoring system and 24-h post-operative parathyroid hormone (PTH) levels, as well as its capability of ...

Background: Metastatic insulinomas are very rare (fewer than 1:100000) and therefore may pose a therapeutic challenge as there are no case controlled studies comparing the efficacy of various therapeutic approaches avialable. The Ki 67 index from the histology of the primary tumour is an established prognostic marker for metastatic disease with tumours showing low Ki 67(<3%) being defined as low risk of early recurrence.Case Presentation: A 60 year o...

Introduction: LMTK3 is an oncogenic Receptor Tyrosine Kinase (RTK) implicated in resistance to endocrine therapy in breast cancer. Initially, LMTK3 was described as a regulator of Estrogen Receptor alpha (ERα) since it was found able to protect it from ubiquitin-mediated proteasomal degradation. In a cohort of breast cancer (BC) patients (n>600), LMTK3 protein levels and intronic polymorphisms were significantly associated with disease-free and overall surviv...

Introduction: Glucocorticoids are used for treatment of various hematological malignancies such as Acute Myeloid Leukemia (AML). Glucocorticoids are known to induce apoptosis by regulating the expression of key anti- or pro-apoptotic genes. Vitamin D induces apoptosis and cell cycle arrest in various types of cancer cells. Despite recent advances in treatment of AML, the poor response rate to therapy remains a big challenge.Therefore, discovering new factors that can affect th...

IntroductionEndometriosis is a dysplastic disease affecting approximately 7–10% of reproductive–aged women. It is defined as the presence of endometrial-like tissue outside the uterine cavity. Disruption of circadian rhythm in night shift worker has been associated with menstrual irregularity and increased chance of developing endometriosis and ovarian tumors. The central circadian clock system located in hypothalamic suprachiasmatic nucleus (...

PurposeThere is a continuity of changes ranging from enterochromaffin‐like (ECL) cell hyperplasia to type 1 gastric neuroendocrine neoplasms (GNEN1) with important clinical implications. Although the effect of the circadian clock system on tumorigenesis has been addressed, the role of the peripheral clock system in the transition from ECL-cell hyperplasia to GNEN1 remains to be explored.MethodsSix patie...

Introduction: Non-alcoholic fatty liver disease (NAFLD) is the commonest cause of chronic liver disease in the western world affecting 5-33% of the general population. Polycystic ovarian syndrome (PCOS) is a common endocrinopathy affecting 6-10% of women of reproductive age. In both conditions, insulin resistance (IR) seems to be a common pathogenetic mechanism.Objective: To investigate the presence of NAFLD in lean and obese women with and without PCOS ...

Introduction: Gastric neuroendocrine tumors (GNET) are rare gastric neoplasms which are developed due to hypergastrinemia and enterochromaffin-like (ECL) cell hyperplasia. Although the effect of the circadian clock system disruption on tumorigenesis has been already studied in various malignancies and autoimmune diseases, the role of the peripheral clock system in the transition from ECL-cell hyperplasia to GNEN1 (Type 1 Gastric Neuroendocrine Neoplasms) remains unexplored.</p...

Introduction: The biological rhythm pattern is synchronized through circadian oscillation of cortisol and melatonin release. Increased cortisol levels and circadian rhythm disruption act as an oncogenic factor in endometrial cancer through among others- dysregulation of cell proliferation/apoptosis and invasion.Aim: To investigate, whether there is an oscillatory expression of the clock genes, MT1 and GR expression in human endometrial carcinoma cells.
