Ubiquitin specific protease 7 deubiquitinates and regulates Aurora B-mediated cytokinesis.

Aurora B is a widely studied mitotic checkpoint kinase that forms a part of the chromosomal passenger complex. The entry to and exit from mitosis are exquisitely controlled by Aurora B proteins, which regulate mitotic phases including chromosomal condensation, segregation, and cytokinesis, ensuring faithful propagation of daughter cells. Abnormal regulation of Aurora B proteins during the cell cycle can cause increased chromosomal segregation errors and ultimately lead to cancer.

Targeting USP11 counteracts -associated interstitial lung disease in hiPSCs-derived alveolar organoids and in vivo models.

Interstitial lung disease (ILD) is a pulmonary disorder characterized by a combination of inflammation and fibrosis in the lung parenchyma, which initiates with the dysfunction of alveolar epithelial cells (AECs). The alveolar cells secrete surfactant proteins that lowers the surface tension of fluids in the lungs and maintains the stability of pulmonary tissue. Mutations on surfactant protein C (SFTPC), particularly I73T, are associated with a toxic gain of function that causes misfolding and the accumulation of immature SFTPC proteins, triggering pulmonary fibrosis (PF).

Loss of Ubiquitin-Specific Protease 11 Mitigates Pulmonary Fibrosis in Human Pluripotent Stem Cell-Derived Alveolar Organoids.

The etiology of chronic and lethal interstitial lung disease, termed idiopathic pulmonary fibrosis (IPF), remains unidentified. IPF induces pathological lung scarring that results in rigidity and impairs gas exchange, eventually resulting in premature mortality. Recent findings indicate that deubiquitinating enzymes play a key role in stabilizing fibrotic proteins and contribute to pulmonary fibrosis.

Recent progress in CRISPR/Cas9 system for eye disorders.

Ocular disorders encompass a broad spectrum of phenotypic and clinical symptoms resulting from several genetic variants and environmental factors. The unique anatomy and physiology of the eye facilitate validation of cutting-edge gene editing treatments. Genome editing developments have allowed researchers to treat a variety of diseases, including ocular disorders.

Advances in applications of the CRISPR/Cas9 system for respiratory diseases.

Genetic and environmental factors can have an impact on lung and respiratory disorders which are associated with severe symptoms and have high mortality rates. Many respiratory diseases are significantly influenced by genetic or epigenetic factors. Gene therapy offers a powerful approach providing therapeutic treatment for lung diseases.

βTrCP1 promotes SLC35F2 protein ubiquitination and inhibits cancer progression in HeLa cells.

The solute carrier family 35 F2 (SLC35F2) belongs to membrane-bound carrier proteins that are associated with multiple cancers. The main factor that determines cancer progression is the expression level of SLC35F2. Thus, identifying the E3 ligase that controls SLC35F2 protein abundance in cancer cells is critical.

E3 ubiquitin ligase APC/C regulates SLC35F2 protein turnover and inhibits cancer progression in HeLa cells.

Background: The solute carrier family 35 F2 (SLC35F2), belongs to membrane-bound carrier proteins that control various physiological functions and are activated in several cancers. However, the molecular mechanism regulating SLC35F2 protein turnover and its implication in cancer progression remains unexplored. Therefore, screening for E3 ligases that promote SLC35F2 protein degradation is essential during cancer progression.
