Molecular basis of the bone disorders in patients with acromegaly are largely unknown.Objective: To investigate microRNAs (miRNA) expression profiles that regulate bone metabolism in plasma samples from patients with acromegaly.Materials and methods: Fasting plasma samples were taken from consecutive subjects with biochemically confirmed active acromegaly and healthy volunteers matched by age, sex and BMI. IGF1 was measured by an e...

Molecular basis of the bone disorders in patients with acromegaly are largely unknown.Objective: To investigate gene expression profiles that regulate bone metabolism in bone tissue samples from patients with acromegaly.Materials and Methods: Patients with clinically evident and biochemically proven active acromegaly and patients with hormonally inactive pituitary adenoma matched by age, sex and BMI were invited to participate. Bon...

Background: Plasma microRNAs (miRs) (miR-4446-3p, miR-215-5p, miR-342-5p) were downregulated in patients with active acromegaly (AM) compared with healthy control subjects as assessed by next-generation sequencing.Aim: The aim of this study wasto validate the previously observed finding in the newly enrolled patients with AM using qRT-PCR.Materials and methods: Morning plasma samples were collected from fasting patients with AM and...

Introduction: ACTH-secreting pituitary adenoma tissue differs from normal pituitary gland tissue in microRNA (miR) expression. MiRs are secreted into circulation and can be detected as potential biomarkersAim: To evaluate the difference in miR levels in plasma samples drained from inferior petrosal sinuses in patients with Cushing’s disease (CD) and ectopic-ACTH syndrome (EAS).Materials and methods: we enrolled 24 patients wi...

Multiple endocrine neoplasia type 1(MEN1) is a hereditary condition caused by mutations in the MEN1 gene, which encodes menin protein. The syndrome predisposes to the development of tumors in both endocrine and non-endocrine systems. In patients with MEN1, pituitary adenomas (PA) occur in approximately 40% of all cases. If patient has MEN1 phenotype with no mutations in MEN1 gene, the condition is regarded as a phenocopy. The reason of several endocrine MEN1-...

According to previous research microRNA (miR) are expressed differently in corticotropinoma and ACTH-secreting neuroendocrine tumors. MiR are released into circulation by several mechanisms and considered to be promising biomarkers.Objective: To evaluate whether preselected miR are differently expressed in plasma samples of patients with ACTH-dependent Cushing’s syndrome (CS).Materials and methods: The blood samples were colle...

Introduction: Recent studies have shown that microRNA could serve as biomarkers in various types of cancer and other diseases. Aim: To reveal microRNA that differ in patients with Cushing’s diseases (CD) and Ectopic ACTH-syndrome (EAS) to form a specific panel for differential diagnosis of ACTH-dependent Cushing’s syndrome (CS).Materials and Methods: Plasma samples from both sinuses and cubital vein were drained during in...
