Gastric cancer (GC) remains the most common malignant tumor of the gastrointestinal tract and one of the leading causes of cancer-related deaths worldwide. Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), are involved in the pathogenesis and progression of GC and, therefore, may be potential diagnostic and prognostic biomarkers. Our work was aimed at investigating the predicted regulation of by miR-129-5p and miR-3613-3p and the clinical value of their aberrant expression in GC.

The rarity and variability of MEN1-related primary hyperparathyroidism (mPHPT) has led to contradictory data regarding the bone phenotype in this patient population. A single-center retrospective study was conducted among young age- and sex-matched patients with mPHPT and sporadic hyperparathyroidism (sPHPT). The main parameters of calcium-phosphorus metabolism, bone remodeling markers, and bone mineral density (BMD) measurements were obtained during the active phase of hyperparathyroidism before parathyroidectomy (PTE) and 1 year after.

Unlabelled: MicroRNAs and the WNT signaling cascade regulate the pathogenetic mechanisms of atherosclerotic coronary artery disease (CAD) development.

Objective: To evaluate the expression of microRNAs (miR-21a, miR-145, and miR-221) and the role of the WNT signaling cascade (WNT1, WNT3a, WNT4, and WNT5a) in obstructive CAD and ischemia with no obstructive coronary arteries (INOCA).

Method: The cross-sectional observational study comprised 94 subjects.

Article Synopsis
  • - Rheumatoid arthritis (RA) is influenced by both genetics and environmental factors, with specific gene variants like HLA-DRB1 and others identified as significant risk factors for the disease when combined.
  • - A study genotyped 125 RA patients and found associations between certain genotypes and clinical measures, such as disease activity scores and biochemical factors like anti-citrullinated peptide antibodies.
  • - The use of targeted next-generation sequencing (NGS) allows for more detailed genetic analysis, aiding in the identification of at-risk groups among RA patients.

Background: In a previous study we found that in chickweed the expression level of the pro-SmAMP2 gene was comparable or even higher to that of the β-actin gene. This high level of the gene expression has attracted our attention as an opportunity for the identification of novel strong promoters of plant origin, which could find its application in plant biotechnology. Therefore, in the present study we focused on the nucleotide sequence identification and the functional characteristics of the pro-SmAMP2 promoter in transgenic plants.
