Background: Patients affected by gliomas have a poor prognosis. Astrocytoma is a subtype of glioma. Identification of biomarkers could be an effective way to an early diagnosis of tumor or to distinguish more aggressive tumors that need more intensive therapy. In this study, we investigated whether the expression of miR-362 was increased or decreased in patients with different grades of astrocytoma.
Materials And Methods: miR-362 expression was compared in 25 patients with astrocytoma with that of 4 normal nonneoplastic brain tissues.
Results: In all tumor tissues, the expression of miR-362 was significantly decreased relative to its expression in normal brain tissues. However, there was no significant difference between miR-362 expressions in high and low grades of astrocytoma.
Conclusions: In conclusion, miR-362 showed a down-regulation pattern in astrocytoma tissues that was different from the pattern obtained from previously published microarray studies.

MicroRNAs (miRNAs) are essential post-transcriptional regulators of gene expression involved in a broad range of biological activities. Recent studies have increasingly highlighted their significant role in the development and progression of various human cancers. Among these, miR-362 has emerged as a context-dependent molecule, exhibiting both oncogenic and tumor-suppressive functions across different malignancies.

Background: Single-nucleotide polymorphisms (SNPs) are associated with multiple disorders and various cancer types. In the context of cancer, alterations within non-coding regions, specifically 3' untranslated regions (3' UTR), have proven substantially important.
Methods: In this study, we utilized various bioinformatics tools to examine the effect of SNPs in the 3' UTR.

Introduction: infection induced miRNA dysregulation plays an important role in gastric cancer (GC) and exosomes mediate the spread of pathogenic effects.
Methods: Expression of miR-362-5p and its clinical significance in GC were analyzed using data from TCGA. The effects of miR-362-5p on GC cells' proliferation and migration were examined by using CCK-8, EdU, transwell and scratch assays.

Endogenous neural stem cells (ENSCs) have multi-lineage differentiation capabilities and are believed to be a natural resource for treating ischemic stroke. However, persistent ischemia and hypoxic stimulation induce ENSCs death and their differentiation into glial cells, thereby limiting endogenous neural repair. Previous research has shown that human neural stem cell-derived small extracellular vesicles (hNSC-sEVs) can improve the survival and differentiation of ENSCs into neurons in rats with cerebral ischemia.

Hydroxyurea promotes HbF elevation in b-thalassemia and sickle cell anemia patients however, its mechanism is not completely elucidated. Previous studies have associated microRNAs with the regulation of HBG2, prompting this study to investigate specific microRNAs linked to HbF regulation in patients treated with hydroxyurea. 150 patients were recruited in the study.
