miR-PAIR: microRNA-protein analysis of integrative relationship for the identification of significantly working miRNAs.

MicroRNAs (miRNAs), which are small non-coding RNAs, are recognized as important significant endogenous bio-molecules that regulate the post-transcriptional processes of target genes. However, predictive methods for significantly working miRNAs are poorly understood. The present study aimed to establish a novel method, miRNA protein analysis of integrative relationship (miR-PAIR), for the identification of effectively working miRNAs involved in physiological or pathological events.

Evaluation of molecular interaction between intercellular lipid organization in human stratum corneum and terpenes using time-resolved synchrotron X-ray diffraction.

The stratum corneum (SC) presents certain limitations for topical administration of medication, which can be overcome using penetration enhancers (PEs) such as terpene (TP). The SC is also crucial for maintaining the skin barrier and consists of two lamellar structures: the short periodicity phase (SPP) and long periodicity phase (LPP). In this study, we monitored changes in the X-ray diffraction peaks of the human SC, 30 min after TP application (neroridol, 1,8-cineol, and d-limonene).

Abemaciclib-induced epithelial-mesenchymal transition mediated by cyclin-dependent kinase 4/6 independent of cell cycle arrest pathway.

Abemaciclib (ABM), a cyclin-dependent kinase 4/6 inhibitor, shows pharmacological effects in cell cycle arrest. Epithelial-mesenchymal transition is an important cellular event associated with pathophysiological states such as organ fibrosis and cancer progression. In the present study, we evaluated the contribution of factors associated with cell cycle arrest to ABM-induced epithelial-mesenchymal transition.

Anti-Helicobacter pylori activity of swertianolin, isolated from swertia herb.

Helicobacter pylori is a Gram-negative, spiral-shaped, motile bacterium present in human stomachs that causes gastric ulcers. A preliminary screening revealed that a methanolic extract of swertia herb demonstrated anti-H. pylori activity.

Role of integrin α2 in methotrexate-induced epithelial-mesenchymal transition in alveolar epithelial A549 cells.

Methotrexate (MTX) is widely used to treat various diseases. However, it induces adverse reactions like serious lung injury, including pulmonary fibrosis. Increasing evidence suggests that epithelial-mesenchymal transition (EMT) in injured alveolar epithelium contributes to the development of the pathophysiological state of the lung.
