Background: This study aims to investigate the regulatory effect of microRNA-96-5p (miR-96-5p) in the pathophysiological process of allergic rhinitis (AR).
Methods: Nasal mucosal tissue samples were collected from AR patients and healthy controls. An in vitro AR model was established by stimulating human nasal epithelial cells (HNECs) with interleukin (IL)-13. The expressions of target genes and proteins were measured by qPCR, Western blot, or ELISA. Dual-luciferase reporter assay and pull-down assay were performed to confirm the interaction between miR-96-5p and DEP domain-containing mammalian target of rapamycin-interacting protein (DEPTOR).
Results: The level of miR-96-5p was increased while the expression of DEPTOR was decreased in AR patients. The expressions of proinflammatory cytokines were markedly increased and the mammalian target of rapamycin (mTOR)/NF-κB pathway was activated in HNECs following IL-13 stimulation. miR-96-5p downregulation alleviated the stimulated function by IL-13. DEPTOR was the target of miR-96-5p. Knockdown of DEPTOR reversed the function of miR-96-5p inhibitor on IL-13-stimulated HNECs.
Conclusions: The current study showed that miR-96-5p and DEPTOR were aberrantly expressed in AR nasal mucosa. miR-96-5p knockdown inhibited the production of inflammatory cytokines and the activation of mTOR/NF-κB pathway via targeting DEPTOR. These findings suggested that miR-96-5p might be used as a diagnostic marker and therapeutic target for the treatment of AR.

Background: Non-smoking women with lung adenocarcinoma(NSWLA) is a significant health problem globally; the carcinogenesis and prognostic signature remain poorly understood. Circular RNAs (circRNAs) are gradually implicated in cancer formation through sponging miRNAs to regulate mRNAs.
Methods: Tumor and paracancerous specimens from non-smoking women after lung adenocarcinoma surgery were collected for high-throughput sequencing of circRNA.

With prolonged ethanol ingestion, disturbances in the emotional spectrum develop, and memory problems are noted. These symptoms could be mediated by the development of neurochemical changes in the hippocampus of the brain. Although there is evidence that hippocampus is vulnerable to chronic alcohol intoxication and that neuroinflammation and neurodegeneration develop in this brain region, the key molecular mechanisms have not been identified.

Wooden breast (WB) myopathy has raised a worldwide concern among broiler industry during the past decade. Despite progress in understanding its etiology from transcriptional regulation, post-transcriptional mechanisms including the regulation of microRNAs (miRNAs) remain largely unknown. In the current study, we described an integrative analysis between mRNA and miRNA expression profiles of pectoralis major muscle from normal and WB myopathic broilers.
