Background: The upregulation of miRNA-155 (miR-155) has been associated with oncogenesis of many human tumors, including nasopharyngeal carcinoma (NPC). However, the profile of miR-155 in Vietnamese NPC patients has not been investigated. The current study aimed to evaluate the miR-155 expression and assess whether miR-155 is a potential biomarker for diagnosis of NPC in Vietnamese patients.
Methods: In current case-control study, total of RNA was isolated from 60 biopsy NPC samples and 60 non-cancerous swab samples were analyzed by Reverse-transcription PCR, qualitative Real-time PCR.
Results: The frequency of miR-155 detection were 78.33%, 15.0% in NPC and non-cancerous samples (<0.05), respectively. The miR-155 expression level was 4.92 times higher in tumor samples than non-cancerous sample.
Conclusion: Taken together, miR-155 in NPC was upregulated. It may serve as a potential biomarker for NPC in the Vietnamese population.

The development of an engineered RNA device capable of detecting multiple biomarkers to evaluate pathological states and autonomously implement responsive therapies is urgently needed. Here, we report InCasApt, an integrated nano CRISPR Cas13a/RNA aptamer theranostic platform capable of achieving both biomarker detection and biomarker-driven therapy. Within this system, a Cas13a/crRNA complex, a hairpin reporter (HR), a dinitroaniline caged Ce6 photosensitizer (Ce6-DN), and a DN-binding RNA aptamer precursor (DNBApt) are coloaded onto dendritic mesoporous silicon nanoparticles (DMSN) in a controlled manner.

MicroRNAs (miRNAs) play crucial roles in the regulation of immune cell differentiation and the immune response during allergic rhinitis (AR). Studies have shown that miRNA-155 is significantly upregulated in AR pathogenesis. Therefore, miRNA-155 can be used as a biomarker for AR diagnosis.

Background: Airway epithelial cells (AECs) and alveolar macrophages are involved in airway inflammation. The direct effects of atmospheric fine-particulate-matter (PM2.5) on airway cells, such as AECs and alveolar macrophages, have been widely investigated, but the effect of cell-cell interaction on inflammatory response remains unclear.

CD4+ T cells are considered the main orchestrators of autoimmune diseases. Their disruptive effect on CD4+ T cell differentiation and the imbalance between T helper cell populations can be most accurately determined using experimental autoimmune encephalomyelitis (EAE) as an animal model of multiple sclerosis (MS). One epigenetic factor known to promote autoimmune inflammation is miRNA-155 (miR-155), which is significantly upregulated in inflammatory T cells.

Background: The current research examines the molecular terrain of celiac disease (CD) through microRNA (miRNA) and cytokines as potential new diagnostic and therapeutic markers. Gluten-appropriate immune response is a key feature of an autoimmune clinical entity known as CD that leads to inflammation and degeneration of small intestine mucosa. However, the mechanisms responsible for this remain unclear.
