Cytokine 2023; 164:156123. [PMID: 36796259 DOI: 10.1016/j.cyto.2023.156123] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 11/02/2022] [Accepted: 12/30/2022] [Indexed: 02/16/2023]
Abstract
BACKGROUND Psoriasis is a chronic autoimmune skin disease with unclear pathogenesis. It was found that miR-149-5p was significantly decreased in psoriatic lesion tissues. In this study, we aims to investigate the role and related molecular mechanism of miR-149-5p on psoriasis. METHOD IL-22 was used to stimulate HaCaT and NHEK cells to establish psoriasis model in vitro. The miR-149-5p and phosphodiesterase 4D (PDE4D) expression levels were detected by quantitative real-time PCR. HaCaT and NHEK cells proliferation was determined by Cell Couting Kit-8 assay. The cell apoptosis and cell cycle were detected by flow cytometry. The cleaved Caspase-3, Bax and Bcl-2 protein expressions were detected by western blot. The targeting relationship between PDE4D and miR-149-5p was predicted and confirmed by Starbase V2.0 and dual-luciferase reporter assay, respectively. RESULT There was a low expression level of miR-149-5p and a high expression of PDE4D in psoriatic lesion tissues. MiR-149-5p could target PDE4D. IL-22 promoted HaCaT and NHEK cells proliferation, while inhibited cell apoptosis and accelerated cell cycle. Moreover, IL-22 decreased the expressions of cleaved Caspase-3 and Bax, and increased the expression of Bcl-2. And the overexpressed miR-149-5p promoted HaCaT and NHEK cells apoptosis, inhibited cell proliferation and retarded cell cycle, meanwhile increased the cleaved Caspase-3 and Bax expressions, decreased the Bcl-2 expression. In addition, PDE4D overexpression has the opposite effect as miR-149-5p. CONCLUSION The overexpressed miR-149-5p inhibits IL-22-stimulated HaCaT and NHEK keratinocytes proliferation, promotes cell apoptosis and retards cell cycle by down-regulating the expression of PDE4D, which could be the promising therapeutic target of psoriasis.

Abstract
BACKGROUND Metabolite genome-wide association studies (mGWAS) are key for understanding the genetic regulation of metabolites in complex diseases including cancers. Although mGWAS has revealed hundreds of metabolomics quantitative trait loci (mQTLs) in the general population, data relating to gastric cancer (GC) are still incomplete. METHODS We identified mQTLs associated with GC by analyzing genome-wide and metabolome-wide datasets generated from 233 GC patients and 233 healthy controls. RESULTS Twenty-two metabolites were statistically different between GC cases and healthy controls, and all of them were associated with the risk of gastric cancer. mGWAS analyses further revealed that 9 single nucleotide polymorphisms (SNPs) were significantly associated with 3 metabolites. Of these 9 SNPs, 6 loci were never reported in the previous mGWAS studies. Surprisingly, 4 of 9 SNPs were significantly enriched in genes involved in the T cell receptor signaling pathway. CONCLUSIONS Our study unveiled several novel GC metabolite and genetic biomarkers, which may be implicated in the prevention and diagnosis of gastric cancer.

Abstract
Cyclic nucleotide phosphodiesterases (PDE) break down cyclic nucleotides such as cAMP and cGMP, reducing the signaling of these important intracellular second messengers. Several unique families of phosphodiesterases exist, and certain families are clinically important modulators of vasodilation. In the current work, we have summarized the body of literature that describes an emerging role for the PDE4 subfamily of phosphodiesterases in malignancy. We have systematically investigated PDE4A, PDE4B, PDE4C, and PDE4D isoforms and found evidence associating them with several cancer types including hematologic malignancies and lung cancers, among others. In this review, we compare the evidence examining the functional role of each PDE4 subtype across malignancies, looking for common signaling themes, signaling pathways, and establishing the case for PDE4 subtypes as a potential therapeutic target for cancer treatment.

Abstract
BACKGROUND Phosphodiesterase 4D (PDE4D) has recently been reported as an oncogene in various types of human cancers. However, the expression and significance of PDE4D in pancreatic ductal adenocarcinoma (PDAC) have not been elucidated. Methods: Immunohistochemistry (IHC) was used to examine the expression of PDE4D in 104 clinicopathologically characterized PDAC cases. PDE4D expression in paired tumor tissues and adjacent noncancerous tissues were detected by western blotting and real time qRT-PCR. The correlation of PDE4D expression levels with clinicopathological features and prognosis in patients were analyzed by univariate and multivariate methods. Effect of PDE4D on pancreatic cancer cells was detected by cell migration and invasion assays. Results: We found that PDE4D was significantly up-regulated in PDAC tumor tissues compared to those paired adjacent noncancerous tissues at both protein and mRNA levels. High level of PDE4D was significantly associated with clinical stage (P = 0.004), T classification (P = 0.003), lymph node metastasis (P = 0.022) and liver metastasis (P = 0.038). Patients with higher levels of PDE4D had shorter overall survival time contrast with those with lower PDE4D expression (P = 0.002). Multivariate analysis indicated that PDE4D may be an independent prognostic factor for PDAC. PDE4D depletion significantly suppressed β-catenin and Snail expression as well as the migration and invasion abilities of pancreatic cancer cells. Conclusions: Our study reveals that PDE4D up-regulated in PDAC was closely associated with poor prognosis of PDAC patients and multiple aggressive clinicopathological characteristics. PDE4D could be a useful prognostic biomarker and therapeutic target for PDAC.

Abstract
Colorectal cancer (CRC) is a major worldwide health problem due to its high prevalence and mortality rate. microRNA has been reported playing an important role in a variety of cancers including colorectal cancer. miR-203a-3p has been found up-regulated in CRC tissues compare with the adjacent normal tissues. But, how miR-203a-3p regulates CRC development remains to be elucidated. In this study, gain and loss-of-function assays showed that miR-203a-3p promotes colorectal cancer cell proliferation, colony formation and migration and invasion by targeting PDE4D. And miR-203a-3p/β-catenin/Cyclin D1/c-Myc signaling pathway is involved in the CRC. In summary, this study highlights an onco-miRNA role for miR-203a-3p by regulating PDE4D in CRC and suggests that miR-203a-3p may be a novel molecular therapeutic target for CRC.

Abstract
Postoperative radiotherapy or concurrent chemoradiotherapy are routine clinical options for the treatment of head and neck squamous cell carcinoma (HNSCC). However, the benefit of adding chemotherapy to radiotherapy is contested. The present study aimed to develop a gene signature to predict the clinical benefit of postoperative chemoradiotherapy using public data from The Cancer Genome Atlas. A 22-gene signature was established, which demonstrated the best predictive value. Patients were separated into low-score and high-score subgroups based on the expression score of the 22-gene signature. In the high-score subgroup, patients who received chemoradiotherapy demonstrated improved overall survival, relapse-free survival and local regional control compared with those who received radiotherapy alone. However, in the low-score subgroup adding chemotherapy to radiotherapy was associated with worse patient outcomes. The predictive value of the 22-gene signature was independent of the conventional clinical variables. Gene set enrichment analysis revealed that the expression signatures of hypoxia phenotype and stem-like traits were significantly enriched in the low-score subgroup. In addition, the low-score subgroup was associated with the gene sets involved in resistance to anticancer drugs. In conclusion, hypoxia- or stem-like gene expression properties are associated with chemotherapy-resistance in HNSCC. The 22-gene signature may be useful as a predictive marker to help distinguish patients who will benefit from postoperative concurrent chemoradiotherapy.

Oncol Lett 2018; 15:6147-6160. [PMID: 29616096 PMCID: PMC5876445 DOI: 10.3892/ol.2018.8105] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2016] [Accepted: 10/13/2017] [Indexed: 12/20/2022] Open
Abstract
Long non-coding RNA HOXA11 antisense RNA (HOXA11-AS) has been previously reported to be involved in the tumorigenesis and progression of ovarian cancer and glioma. However, the function of HOXA11-AS in lung cancer remains unclear. Following the knockdown of HOXA11-AS in A549 cells, a microarray analysis was performed in order to detect the differences in microRNA (miRNA/miR) profiles. Subsequently, miR-642b-3p was selected for further analysis. Four miRNA target prediction algorithms were used to identify potential target genes of miR-642b-3p. Bioinformatics analyses, including Gene Ontology (GO), Kyoto Encyclopaedia of Genes and Genomes, protein-protein interactions (PPIs) and network analysis, were performed to investigate the potential functions, pathways and networks of the target genes. Furthermore, the differential expression of miR-642b-3p and its target genes between normal lung and non-small cell lung cancer (NSCLC) tissues was verified using The Cancer Genome Atlas (TCGA) database. Six target genes [zinc finger protein 350, heterogeneous nuclear ribonucleoprotein U, high mobility group box 1, phosphodiesterase 4D (PDE4D), synaptotagmin binding cytoplasmic RNA interacting protein and basic helix-loop-helix family member B9] of miR-642b-3p were predicted using all 4 algorithms. It was revealed that miR-642b-3p was overexpressed in adenocarcinoma and squamous cell carcinoma tissues compared with non-cancerous lung tissues based on the TCGA database. From the 6 target genes, PDE4D was downregulated in lung adenocarcinoma and squamous cell carcinoma tissues, and a weak negative correlation between HOXA11-AS and PDE4D was identified. The area under the curve of PDE4D was 0.905 [95% confidence interval (CI), 0.879–0.931] for patients with lung adenocarcinoma and 0.665 (95% CI, 0.606–0.725) for patients with squamous cell carcinoma. Additionally, GO analysis of the target genes revealed that miR-642b-3p was specifically involved in complex cellular pathways. The target gene RAN binding protein 2 possessed the highest degree of interactions in the PPI network (degree=40). It was hypothesized that HOXA11-AS may have a function in NSCLC by regulating the expression of miR-642b-3p and PDE4D, which laid the foundation for the further elucidation of the potential molecular mechanisms of NSCLC.

Abstract
ETHNOPHARMACOLOGIC RELEVANCE Berberine (BBR) is a naturally occurring alkaloid compound that can be found in Chinese medicinal herbs such as Rhizoma Coptidis and Phellodendri Cortex. These BBR containing herbs are commonly used by Chinese medicine doctors to treat cancers including melanoma. In this study, we explored proteins potentially involved in the anti-melanoma effects of BBR using computational and experimental approaches. MATERIALS AND METHODS Target proteins of BBR were predicted using the reverse pharmacophore screening, molecular docking and molecular dynamics. Anti-melanoma activities of BBR in melanoma cells were examined by MTT and EdU proliferation assays. Effects of BBR on activities of target proteins in melanoma cells were examined by Western blotting or fluorescence assay. RESULTS Ten proteins implicated in cancer and with high fit-score in the reverse pharmacophore screening were selected as potential targets of BBR. Molecular docking and molecular dynamics revealed that BBR could stably bind to four of the ten proteins, namely 3-phosphoinositide-dependent protein kinase 1 (PDK1), glucocorticoid receptor (GR), p38 mitogen-activated protein kinase (p38) and dihydroorotate dehydrogenase (DHODH). Cellular experiments showed that BBR inhibited cell proliferation, increased the phosphorylation of GR and p38, and inhibited the activity of DHODH in A375 human melanoma cells. CONCLUSIONS These findings suggest that p38, GR and DHODH are potentially involved in the anti-melanoma action of BBR. This study provided a chemical and pharmacological justification for the clinical use of BBR-containing herbs in melanoma treatment.

Abstract
Trichorhinophalangeal 1 (Trps1) is a transcription factor essential for epithelial cell morphogenesis during kidney development, but the role of Trps1 in AKI induced by ischemia-reperfusion (I/R) remains unclear. Our study investigated Trps1 expression during kidney repair after acute I/R in rats and explored the molecular mechanisms by which Trps1 promotes renal tubular epithelial cell proliferation. Trps1 expression positively associated with the extent of renal repair after I/R injury. Compared with wild-type rats, rats with knockdown of Trps1 exhibited significantly delayed renal repair in the moderate I/R model, with lower GFR levels and more severe morphologic injury, whereas rats overexpressing Trps1 exhibited significantly accelerated renal repair after severe I/R injury. Additionally, knockdown of Trps1 inhibited and overexpression of Trps1 enhanced the proliferation of renal tubular epithelial cells in rats. Chromatin immunoprecipitation sequencing assays and RT-PCR revealed that Trps1 regulated cAMP-specific 3',5'-cyclic phosphodiesterase 4D (Pde4d) expression. Knockdown of Trps1 decreased the renal protein expression of Pde4d and phosphorylated Akt in rats, and dual luciferase analysis showed that Trps1 directly activated Pde4d transcription. Furthermore, knockdown of Pde4d or treatment with the phosphatidylinositol 3 kinase inhibitor wortmannin significantly inhibited Trps1-induced tubular cell proliferation in vitro Trps1 may promote tubular cell proliferation through the Pde4d/phosphatidylinositol 3 kinase/AKT signaling pathway, suggesting Trps1 as a potential therapeutic target for kidney repair after I/R injury.
