Besides the genetic research, increasing number of scientific studies focus on epigenetic phenomena - such as DNA methylation - regulating the expression of genes behind the phenotype, thus can be related to the pathomechanism ...

The authors present the case of a 63-year-old man who was evaluated for symptoms of lung fibrosis, blue face and epithelopathy affecting both eyes. All these symptoms could be attributed to the adverse effects of amiodarone. ...

Adrenocortical tumours are quite prevalent. Most of these tumours are benign, hormonally inactive adrenocortical adenomas. Rare hormone-secreting adrenocortical adenomas are associated with severe clinical consequences, ...

Purpose. The interaction of hormones of the pituitary-adrenal axis and adrenal cortex-associated circulating microRNAs is mostly unknown. We have studied the effects of dexamethasone and adrenocorticotropin on the expression ...

INTRODUCTION: Cell-free DNA (cfDNA) was first detected in human plasma in the 1940s, but the knowledge on its regulation and rate of release is incomplete. CfDNA can originate from both normal and tumour cells. AIM: Our ...

Carcinoids are rare tumors originating from neuroendocrine cells. A large proportion of these tumors produce serotonin and other biologically active hormones which may produce carcinoid syndrome characterized by flushing, ...

MicroRNAs (miRNA, miR) are short - 19-25 nucleotide long - single stranded (in their mature form), non-coding RNA molecules that regulate gene expression mostly at the posttranscriptional level. microRNAs are involved in ...
