Abstract
TRIM58 is a member of the TRIM protein family, which possess with E3 ubiquitin ligase activities. Studies have revealed that low expression of TRIM58 plays key roles, has been implicated in the tumor progression of tumor formation due to its reduced expression. However, its role in regulating the stemness of breast cancer stem cells (CSCs) remains unexplored. Here, we found that TRIM58 was underexpressed in TNBC tissues and cells compared to adjacent mucosa tissue, and its downregulation was significantly associated with shorter survival. Overexpression of TRIM58 reduced the proportion of CD44 + /CD24- cells, upregulated differentiation genes, and inhibited stemness-related gene expression in TNBC CSCs. In vitro and in vivo experiments revealed that TRIM58 overexpression in CSCs suppressed tumor sphere formation and tumorigenic capacity. Co-IP results indicated direct interaction between TRIM58 and MYH9, with TRIM58 inducing MYH9 degradation via ubiquitination in differentiated cells. Label-free quantitative proteomics identified GRK3 and Hippo-YAP as downstream targets and signaling pathways of MYH9. TIMER database analysis, immunohistochemistry, western blotting, DNA-protein pulldown experiments, and dual luciferase reporter assays demonstrated that MYH9 regulated GRK3 transcriptional activation in CSCs. In conclusion, elevated TRIM58 expression in CSCs downregulates MYH9 protein levels by promoting ubiquitin-mediated degradation, thereby inhibiting downstream GRK3 transcription, inactivating the YAP stemness pathway, and ultimately promoting CSC differentiation.

Hermawan A, Putri H. Computational analysis of G-protein-coupled receptor kinase family members as potential targets for colorectal cancer therapy. EGYPTIAN JOURNAL OF MEDICAL HUMAN GENETICS 2022.

Abstract
Abstract
Background
G-protein-coupled receptor (GPCR) kinases (GRKs) interact with ligand-activated GPCR, causing intracellular phosphorylation and interfering with the intracellular signal transduction associated with the development of cancer. Colorectal cancer (CRC) is a fast-growing disease, and its molecular mechanism involves various regulatory proteins, including kinases. However, the GRK mechanism in CRC has not been explored.
Methods
We used an integrated computational approach to investigate the potential of GRK family members as targeted proteins in CRC. The GRK expression levels in tumor and normal tissues, colon adenocarcinoma samples, and metastatic colon adenocarcinoma were analyzed using ONCOMINE, GEPIA, and UALCAN, as well as TNM plots. Genetic changes in the GRK family genes were investigated using cBioportal. The prognostic value related to the gene expression of the GRK family was examined using GEPIA and UALCAN. Co-expression analysis of the GRK family was conducted using COXPRESdb. Association analysis of the Gene Ontology, KEGG pathway enrichment, and drug-gene analyses were performed using the over-representation analysis (ORA) in WebGestalt.
Results
GRK2, GRK3, and GRK5 mRNA levels increased significantly in patients with CRC and metastatic CRC. Genetic changes were detected in patients with CRC, including GRK7 (1.1%), GRK2 (1.7%), GRK4 (2.3%), GRK5 (2.5%), GRK6 (2.5%), GRK3 (2.9%), and GRK1 (4%). CRC patients with low mRNA of GRK7 levels had better disease-free and overall survival than those with high GRK7 levels. Hierarchical clustering analysis revealed significant positive correlations between GRK5 and GRK2 and between GRK2 and GRK6. KEGG pathway enrichment analysis showed that the gene network (GN) regulated several cellular pathways, such as the morphine addiction signaling and chemokine signaling pathways in cancer. The drug-gene association analysis indicated that the GN was associated with several drugs, including reboxetine, pindolol, beta-blocking agents, and protein kinase inhibitors.
Conclusion
No research has been conducted on the relation of GRK1 and GRK7 to cancer, particularly CRC. In this work, genes GRK2, GRK3, GRK5, and GRK6 were found to be oncogenes in CRC. Although inhibitors against GRK2, GRK5, and GRK6 have previously been developed, further research, particularly preclinical and clinical studies, is needed before these agents may be used to treat CRC.

GRK3 is a poor prognosticator and serves as a therapeutic target in advanced gastric adenocarcinoma. J Exp Clin Cancer Res 2022; 41:257.

Abstract
Abstract
Background
G protein-coupled receptor (GPCR) is the most targeted protein family by the FDA-approved drugs. GPCR-kinase 3 (GRK3) is critical for GPCR signaling. Our genomic analysis showed that GRK3 expression correlated with poor prognosis of gastric adenocarcinoma (GAC) patients. However, GRK3’s functions and clinical utility in GAC progression and metastases are unknown.
Methods
We studied GRK3 expression in normal, primary, and metastatic GAC tissues. We identified a novel GRK3 inhibitor, LD2, through a chemical-library screen. Through genetic and pharmacologic modulations of GRK3, a series of functional and molecular studies were performed in vitro and in vivo. Impact of GRK3 on YAP1 and its targets was determined.
Results
GRK3 was overexpressed in GAC tissues compared to normal and was even higher in peritoneal metastases. Overexpression (OE) of GRK3 was significantly associated with shorter survival. Upregulation of GRK3 in GAC cells increased cell invasion, colony formation, and proportion of ALDH1+ cells, while its downregulation reduced these attributes. Further, LD2 potently and specifically inhibited GRK3, but not GRK2, a very similar kinase to GRK3. LD2 highly suppressed GAC cells’ malignant phenotypes in vitro. Mechanistically, GRK3 upregulated YAP1 in GAC tissues and its transcriptional downstream targets: SOX9, Birc5, Cyr61 and CTGF. Knockdown (KD) YAP1 rescued the phenotypes of GRK3 OE in GAC cells. GRK3 OE significantly increased tumor growth but LD2 inhibited tumor growth in the PDX model and dramatically suppressed peritoneal metastases induced by GRK3 OE.
Conclusions
GRK3, a poor prognosticator for survival, conferred aggressive phenotype. Genetic silencing of GRK3 or its inhibitor LD2 blunted GRK3-conferred malignant attributes, suggesting GRK3 as a novel therapeutic target in advanced GAC.

G Protein-Coupled Receptor Kinase 4 Is a Novel Prognostic Factor in Hepatocellular Carcinoma. DISEASE MARKERS 2022; 2022:2628879. [PMID: 35769816 PMCID: PMC9236775 DOI: 10.1155/2022/2628879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 04/20/2022] [Accepted: 04/23/2022] [Indexed: 11/25/2022]
Abstract
Purpose We previously reported that G protein-coupled receptor kinase (GRK) 4 halts cell cycle progression and induces cellular senescence in HEK293 cells. The present study was aimed at assessing the prognostic value of GRK4 in hepatocellular carcinoma (HCC). Methods GRK4 expression was detected by immunohistochemistry in paired tumoral and peritumoral tissues of 325 HCC patients. One hundred and twenty-six patients from Western China were utilized as a training cohort to develop a nomogram, while 86 patients from Eastern China were used as a validation cohort. The proliferation and migration of lentiviral-GRK4 expressing HepG2 cells were determined by MTT and wound healing assays. Results GRK4 was differentially expressed in HCC tissues. Tumoral GRK4 intensity, tumor type, and T stage were independent prognostic factors and used to form a nomogram for predicting overall survival (OS), which obtained a good concordance index of 0.82 and 0.77 in training and validation cohort, respectively. The positive and negative prediction values with nomogram were, respectively, 83% and 75% in training cohort and 100% and 52% in validation cohort. Patients with nomogram scores > 32 and 78 showed high risk for OS. Proliferation and motility capabilities were significantly restrained in GRK4-overexpressing HCC cells. Discussion. Low GRK4 expression in HCC tumor tissues indicates poor clinical outcomes. A prognostic nomogram including tumoral GRK4 expression would improve the predictive accuracy of OS in HCC patients. We also demonstrated that GRK4 overexpression inhibits proliferation and migration of HCC cells. The molecular mechanism underlying is worth further study.

Abstract
Abstract
Propose
Laryngeal chondrosarcoma is a rare non-epithelial malignant tumor. At present, the cell type composition and molecular mechanism of laryngeal chondrosarcoma have not been systematically studied.
Methods
This study focused on the histopathological and imaging features of a rare primary laryngeal chondrosarcoma in a 74-year-old male. The tumor and its paracancerous cartilage tissue were single-cell sequenced and analyzed and a total of 5455 single cells were obtained. Immunohistochemical levels were also verified.
Results
In total five cell types were identified, including chondrocytes, myeloid cells, fibroblasts, lymphocytes, and endothelial cells. We carried out further subgroup analysis, focusing on the classification and differentiation of chondrocytes, functional enrichment analysis, and cellular communication analysis of all cell types, and explored the tumor microenvironment (TME) of laryngeal chondrosarcoma. Immunohistochemistry revealed the SLAMF9 gene was specifically expressed in non-immune cells of chondrosarcoma, but was barely expressed in the normal cartilage tissues adjacent to chondrosarcomas.
Conclusion
This single-cell sequencing approach provides clues for deciphering the potential mechanisms of tumor heterogeneity and TME composition in laryngeal chondrosarcoma, and represents an important step towards the treatment of laryngeal chondrosarcoma.

Clin Chim Acta 2018; 478:18-27. [PMID: 29253494 DOI: 10.1016/j.cca.2017.12.017] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Revised: 11/22/2017] [Accepted: 12/12/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND We estimated the diagnostic and prognostic value of serum angiopoietin-2 (Ang-2) in liver cancer patients. METHODS Tissue Ang-2 was measured using immunohistochemistry (IHC). Cell localization of Ang-2 was tested using immunofluorescence (IF). Cell viability and apoptosis were evaluated using MTT and caspase3/7 assays, respectively. Colony-formation was measured using a soft agar assay. Serum Ang-2 was examined using enzyme-linked immunosorbent assay (ELISA) and Western blotting. RESULTS Ang-2 was up-regulated in liver cancer compared to the levels in normal tissues. Serum Ang-2 concentrations were much higher in liver cancer patients than in healthy individuals and those with chronic liver disease (CLD). Inhibitions of Ang-2 using specific shRNA decreased cell proliferation. Serum Ang-2 decreased significantly after surgery. Serum Ang-2 was positively correlated with serum alpha-fetoprotein (AFP; R=0.375, P=0.005). Receiver operating characteristic (ROC) curves suggested that serum Ang-2 could be used with relatively high sensitivity and specificity in differentiating liver cancer patients from CLD patients or healthy controls, with corresponding AUC values of 0.742 and 0.924, respectively. Serum Ang-2 was negatively correlated with overall survival. Subgroup analysis also showed that Ang-2 retained its prognostic value in overall survival prediction in different risk subgroups. CONCLUSION Serum Ang-2 may be a useful tumor marker in predicting liver cancer prognosis.

Abstract
BACKGROUND It was found that G-protein-coupled receptor kinase 3 (GRK3) played key biological roles in some cancers. However, its associations with clinicopathologic features and prognosis in pancreatic ductal adenocarcinoma (PDAC) remain unknown. METHODS AND METHODS Expression of GRK3 was detected, using tissue microarray-based immunohistochemistry, in paired formalin-fixed paraffin-embedded tumor and non-tumor samples from 165 patients with PDAC after curative resection, and was further correlated with clinicopathologic parameters and cancer-specific survival (CSS). RESULTS It was shown that GRK3 expression was much lower in tumor than in non-tumor tissues. Moreover, expression of GRK3 in tumor tissues was significantly associated with gender and T stage. Univariately, high GRK3 expression was predictive for favorable CSS, along with some conventional clinicopathologic variables. In multivariate Cox regression test, GRK3 expression remained to be a significant prognostic marker for PDAC. Finally, combination of GRK3 with some clinicopathologic variables, especially N stage, obtained more precise prediction for CSS. CONCLUSIONS Our data suggested that expression of GRK3 was down-regulated in PDAC and was an independent prognostic factor.
