Exosomal circHIPK3 derived from umbilical cord-derived mesenchymal stem cells enhances skin fibroblast autophagy by blocking miR-20b-5p/ULK1/Atg13 axis.

Background: Umbilical cord-derived mesenchymal stem cells (UCMSCs) could alleviate diabetes-induced injury. Hence, this investigation aimed to explore the role and mechanism of UCMSCs-derived exosomal circHIPK3 (exo-circHIPK3) in diabetes mellitus (DM).

Methods: HFF-1 cells were cultured in high glucose (HG) medium or normal medium, and treated with UCMSCs-derived exo-circHIPK3 or miR-20b-5p mimics or Unc-51-like autophagy activating kinase 1 (ULK1) overexpression vector.

GMI, a fungal immunomodulatory protein, ameliorates SARS-CoV-2 envelope protein-induced inflammation in macrophages via inhibition of MAPK pathway.

Clinically, COVID-19 is often accompanied by a severe immune response (cytokine storm) which produces a large number of cytokines, such as TNF-α, IL-6 and IL-12, and consequently causes acute respiratory distress syndrome (ARDS). GMI is a type of fungal immunomodulatory protein that is cloned from Ganoderma microsporum and acts as modulating immunocyte for various inflammatory diseases. This study identifies GMI as a potential anti-inflammatory agent and determines the effects of GMI on the inhibition of SARS-CoV-2-induced cytokine secretion.

Our study aimed to investigate the regulatory functions of exosomal circHIPK3 and its potential mechanisms in DFU.

GMI, Ganoderma microsporum protein, suppresses cell mobility and increases temozolomide sensitivity through induction of Slug degradation in glioblastoma multiforme cells.

Glioblastoma multiforme (GBM), which is a malignant primary brain tumor, is the cancer that spreads most aggressively into the adjacent brain tissue. Patients with metastatic GBM have a poor chance of survival. In this study, we examined the anti-GBM mobility effect of small protein, called GMI, which is cloned and purified from Ganoderma microsporum.

GMI, a protein from Ganoderma microsporum, induces ACE2 degradation to alleviate infection of SARS-CoV-2 Spike-pseudotyped virus.

Currently, although various vaccines have been developed, humans can still get SARS-CoV-2 infection after being vaccinated. Therefore, the blocking of SARS-CoV-2 infection may be potential therapeutic strategies.
