Abstract
Diabetic retinopathy (DR) is one of the leading causes of blindness in diabetic patients. However, the pathogenesis of DR is complex, and no firm conclusions have been drawn so far. It has become a hot spot in ophthalmology research to deeply study the mechanism of DR pathological changes and find effective treatment options. Human retinal microvascular endothelial cells (HRMECs) were induced by high glucose (HG) to construct DR cell model. CCK-8 assay was used to detect the viability of HRMECs. Transwell assay was used to detect the migration ability of HRMECs. Tube formation assay was used to identify the tube formation ability of HRMECs. The expressions of USP14, ATF2 and PIK3CD were detected by Western blot analysis and qRT-PCR assay. Immunoprecipitation (IP) was used to ascertain the relationship of USP14 and ATF2. To explore the regulatory relationship between ATF2 and PIK3CD by dual-luciferase reporter gene assay and Chromatin immunoprecipitation (ChIP) assay. High glucose treatment promoted the proliferation, migration, and tube formation of HRMEC, and the expressions of USP14, ATF2 and PIK3CD were significantly up-regulated. USP14 or ATF2 knockdown inhibited HG-induced HRMECs proliferation, migration, and tube formation. USP14 regulated the expression of ATF2, and ATF2 promoted PIK3CD expression. PIK3CD overexpression attenuated the inhibitory effectiveness of USP14 knockdown on proliferation, migration and tube formation of DR cell model. Here, we revealed that USP14 regulated the ATF2/PIK3CD axis to promote proliferation, migration, and tube formation in HG-induced HRMECs.

Du XH, Ke SB, Liang XY, Gao J, Xie XX, Qi LZ, Liu XY, Xu GY, Zhang XD, Du RL, Li SZ. USP14 promotes colorectal cancer progression by targeting JNK for stabilization. Cell Death Dis 2023; 14:56.

Abstract
MAPK/JNK signaling is pivotal in carcinogenesis. However, ubiquitin-mediated homeostasis of JNK remains to be verified. Here, with results from RNA sequencing (RNA-seq) and luciferase reporter pathway identification, we show that USP14 orchestrates MAPK/JNK signaling and identify USP14 as a deubiquitinase that interacts and stabilizes JNK. USP14 is elevated in colorectal cancer patients and is positively associated with JNK protein and downstream gene expression. USP14 ablation reduces cancer cell proliferation in vitro and colorectal tumorigenesis in vivo by downregulating MAPK/JNK pathway activation. Moreover, USP14 expression is induced by TNF-α, forming a feedback loop with JNK and leading to tumor amplification. Our study suggests that elevated expression of USP14 promotes MAPK/JNK signaling by stabilizing JNK, which in turn augments colorectal carcinogenesis, indicating a potential therapeutic target for colorectal cancer patients with increased USP14 expression.

Abstract
GNE myopathy is a hereditary muscle disorder characterized by muscle atrophy and weakness initially involving the lower distal extremities. The treatment of GNE myopathy mainly focuses on a sialic acid deficiency caused by a mutation in the GNE gene, but it has not achieved the expected effect. The main pathological features of GNE myopathy are myofiber atrophy and rimmed vacuoles, including accumulation of amyloid β, which is mainly found in atrophic muscle fibers. Although the role of amyloid β and other misfolded proteins on the nervous system has been widely recognized, the cause and process of the formation of amyloid β in the pathological process of GNE myopathy are unclear. In addition, amyloid β has been reported to be linked to quality control mechanisms of proteins, such as molecular chaperones, the ubiquitin–proteasome system, and the autophagy-lysosome system. Herein, we summarize the possible reasons for amyloid β deposition and illustrate amyloid β-mediated events in the cells and their role in muscle atrophy in GNE myopathy. This review represents an overview of amyloid β and GNE myopathy that could help identify a potential mechanism and thereby a plausible therapeutic for the disease.

Abstract
Background Ubiquitin specific peptidase 14 (USP14) and proteasome 26S subunit, non-ATPase 14 (PSMD14) are two deubiquitinases that are closely related to the human 19S proteasome. These are highly expressed in various types of cancers and are associated with prognosis. However, the expression, clinicopathological features, and prognostic relevance of these two deubiquitinases remain unclear in patients with non-small cell lung cancer (NSCLC). Moreover, the correlation between the expression of these two deubiquitinases in NSCLC has not been reported. Methods In this study, the expression of USP14 and PSMD14 in NSCLC tissues and adjacent non-tumor tissues were examined by immunohistochemical staining. The association of these two deubiquitinases with the clinicopathological features and overall survival (OS) of patients with NSCLC was evaluated meanwhile. Results The expression of USP14 and PSMD14 was upregulated in NSCLC tissues compared with adjacent non-tumor tissues. High expression of both these deubiquitinases was positively correlated with the TNM stage of NSCLC. In addition, PSMD14 was positively correlated with lymph node metastasis in NSCLC. The survival analysis showed that elevated levels of USP14 or PSMD14 were associated with poorer survival of NSCLC patients compared with low expression of USP14 or PSMD14. Cox regression analysis indicated that TNM stage, USP14, and PSMD14 were independent prognostic factors for OS in NSCLC. Conclusions This study demonstrated that USP14 and PSMD14 may play important roles in the progression of NSCLC, especially when they are expressed simultaneously at elevated levels. Thus, USP14 and PSMD14 may be potential novel biomarkers and therapeutic targets for the prognosis and treatment of patients with NSCLC.

Abstract
The large family of deubiquitinating enzymes (DUBs) are involved in the regulation of a plethora of processes carried out inside the cell by protein ubiquitination. Ubiquitination is a basic pathway responsible for the correct protein homeostasis in the cell, which could regulate the fate of proteins through the ubiquitin–proteasome system (UPS). In this review we will focus on recent advances on the molecular mechanisms and specificities found for some types of DUBs enzymes, highlighting illustrative examples in which the regulatory mechanism for DUBs has been understood in depth at the molecular level by structural biology. DUB proteases are responsible for cleavage and regulation of the multiple types of ubiquitin linkages that can be synthesized inside the cell, known as the ubiquitin-code, which are tightly connected to specific substrate functions. We will display some strategies carried out by members of different DUB families to provide specificity on the cleavage of particular ubiquitin linkages. Finally, we will also discuss recent progress made for the development of drug compounds targeting DUB proteases, which are usually correlated to the progress of many pathologies such as cancer and neurodegenerative diseases.

FEBS J 2020; 288:1325-1342.

Abstract
Deubiquitinase USP28 plays a crucial role in tumorigenesis by enhancing the stabilities of multiple cancer-related proteins including c-Myc, Notch1, and LSD1, and has become an attractive target for anticancer drug development. However, to date, only a few of USP28-targeted active compounds have been developed, and the active compound-binding pocket in USP28 has not been experimentally revealed yet. In this study, bioassay-based high-throughput screening was applied to discover USP28-targeted inhibitors from the commercially available drug library. Vismodegib, an inhibitor of Hedgehog signaling pathway and FDA-approved drug for the treatment of basal cell carcinoma, was found to exhibit inhibition activity against USP28 (IC50 : 4.41 ± 1.08 μm). Multiple biophysical and biochemical techniques including NMR, ITC, thermal shift assay, HDX-MS, and site-directed mutagenesis analysis were then used to characterize the interaction between Vismodegib and USP28. The binding pocket in USP28 for Vismodegib, which is mainly composed of two helical structures spanning D255-N278 and N286-Y293, was revealed. According to the possible binding pose generated by HDX-MS data-defined molecular docking, the binding cavity occupied by Vismodegib in USP28 aligns well with one of the reported-binding pockets in USP7 for its inhibitors. Furthermore, cellular assays were conducted to confirm that Vismodegib could interact with the evolutionarily related deubiquitinases USP28 and USP25 and downregulate the levels of the two enzymes' substrate proteins c-Myc, Notch1, and Tankyrase-1/2.

Abstract
Ubiquitin (Ub) is a small protein that can be attached to substrate proteins to direct their degradation via the proteasome. Deubiquitinating enzymes (DUBs) reverse this process by removing ubiquitin from its substrate protein. Over the past few decades, ubiquitin-specific protease 14 (USP14), a member of the DUBs, has emerged as an important player in various types of cancers. In this article, we review and summarize biological function of USP14 in tumorigenesis and multiple signaling pathways. To determine its role in cancer, we analyzed USP14 gene expression across a panel of tumors, and discussed that it could serve as a novel bio-marker in several types of cancer. And recent contributions indicated that USP14 has been shown to act as a tumor-promoting gene via the AKT, NF-κB, MAPK pathways etc. Besides, drugs targeting USP14 have shown potential anti-tumor effect and clinical significance. We focus on recent studies that explore the link between USP14 and cancer, and further discuss USP14 as a novel target for cancer therapy.
