[PMID: 38380029 PMCID: PMC10877342 DOI: 10.1016/j.heliyon.2024.e26061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 02/01/2024] [Accepted: 02/07/2024] [Indexed: 02/22/2024] Open
Abstract
Background Although many experiments and clinical studies have proved the link between the expression of CDKN3 and human tumors, we have not been able to identify any bioinformatics study in which the extensive tumor-promoting effect of CDKN3 was systematically analyzed. Objective Explore the extensive tumor-promoting effects of CDKN3 and review the research progress of CDKN3 in cancer. Methods We systematically reviewed the literature on CDKN3 and tumors. We explored the potential tumor-promoting effects of CDKN3 on different tumors in the TCGA database and the GTEx database using multiple platforms and websites. We studied the expression level of CDKN3, survival, prognosis, diagnosis, genetic variation, immune infiltration, and enrichment analysis using databases such as TIMER 2.0, GEPIA2, cBioPortal, and STRING. Results We found that CDKN3 is highly expressed in most tumors. The expression of CDKN3 is closely related to the prognosis of some tumors. And CDKN3 may have diagnostic value. The conclusion of our literature review is roughly the same, but there are differences, which are worthy of further study. Moreover, CDKN3 may be related to immune cell infiltration in tumor tissues. The genetic alteration of LUAD, STAD, SARC, PCPG, and ESCA with "Amplification" as the main type. In addition, through enrichment analysis, we found that CDKN3 affects tumors mainly through the control of the cell cycle and mitosis. Conclusion CDKN3 is highly expressed in most tumor tissues and has a statistical correlation with survival prognosis. It has extensive tumor-promoting effects that may be related to mechanisms such as immune infiltration.

Demir Karaman E, Işık Z. Multi-Omics Data Analysis Identifies Prognostic Biomarkers across Cancers. Med Sci (Basel) 2023; 11:44. [PMID: 37489460 PMCID: PMC10366886 DOI: 10.3390/medsci11030044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 06/18/2023] [Accepted: 06/20/2023] [Indexed: 07/26/2023] Open
Abstract
Combining omics data from different layers using integrative methods provides a better understanding of the biology of a complex disease such as cancer. The discovery of biomarkers related to cancer development or prognosis helps to find more effective treatment options. This study integrates multi-omics data of different cancer types with a network-based approach to explore common gene modules among different tumors by running community detection methods on the integrated network. The common modules were evaluated by several biological metrics adapted to cancer. Then, a new prognostic scoring method was developed by weighting mRNA expression, methylation, and mutation status of genes. The survival analysis pointed out statistically significant results for GNG11, CBX2, CDKN3, ARHGEF10, CLN8, SEC61G and PTDSS1 genes. The literature search reveals that the identified biomarkers are associated with the same or different types of cancers. Our method does not only identify known cancer-specific biomarker genes, but also proposes new potential biomarkers. Thus, this study provides a rationale for identifying new gene targets and expanding treatment options across cancer types.

Abstract
SCOPE It has been proposed that endogenously form N-nitroso compounds (NOCs) are partly responsible for the link between red meat consumption and colorectal cancer (CRC) risk. As nitrite has been indicated as critical factor in the formation of NOCs, the impact of replacing the additive sodium nitrite (E250) by botanical extracts in the PHYTOME project is evaluated. METHOD AND RESULTS A human dietary intervention study is conducted in which healthy subjects consume 300 g of meat for 2 weeks, in subsequent order: conventional processed red meat, white meat, and processed red meat with standard or reduced levels of nitrite and added phytochemicals. Consumption of red meat products enriched with phytochemicals leads to a significant reduction in the faecal excretion of NOCs, as compared to traditionally processed red meat products. Gene expression changes identify cell proliferation as main affects molecular mechanism. High nitrate levels in drinking water in combination with processed red meat intake further stimulates NOC formation, an effect that could be mitigated by replacement of E250 by natural plant extracts. CONCLUSION These findings suggest that addition of natural extracts to conventionally processed red meat products may help to reduce CRC risk, which is mechanistically support by gene expression analyses.

Abstract
Objective Hepatocellular carcinoma (HCC) is one of the most common causes of
cancer-related deaths worldwide. This study investigated the relationship
between cyclin-dependent kinase inhibitor (CDKN)3 and prognosis and
pathological characteristics in HCC patients to determine whether it could
be used as a prognostic factor and/or therapeutic target for HCC drug
development. Methods We previously showed that CDKN3 is deregulated in HCC tumor samples. Here,
bioinformatics analysis was used to assess the relationship between CDKN3
gene expression and the characteristics of HCC patients from Gene Expression
Omnibus and The Cancer Genome Atlas databases. Additionally, CDKN3
expression was silenced by small interfering RNA to determine its effect on
HCC cell proliferation and on HCC cell sensitivity to adriamycin
chemotherapy. Results Bioinformatics analysis showed a negative correlation between CDKN3
expression and both disease-free survival and overall survival. CDKN3
silencing did not significantly suppress the proliferation of HCC cells, but
did decrease their sensitivity to adriamycin. Conclusions CDKN3 may have a dual role during the development of HCC, and could be used
as an independent prognostic factor and therapeutic target for HCC
treatment.

Abstract
Background Hepatocellular carcinoma (HCC) is the most common type of liver tumour, and is closely related to liver cirrhosis. Previous studies have focussed on the pathogenesis of liver cirrhosis developing into HCC, but the molecular mechanism remains unclear. The aims of the present study were to identify key genes related to the transformation of cirrhosis into HCC, and explore the associated molecular mechanisms. Methods GSE89377, GSE17548, GSE63898 and GSE54236 mRNA microarray datasets from Gene Expression Omnibus (GEO) were analysed to obtain differentially expressed genes (DEGs) between HCC and liver cirrhosis tissues, and network analysis of protein–protein interactions (PPIs) was carried out. String and Cytoscape were used to analyse modules and identify hub genes, Kaplan–Meier Plotter and Oncomine databases were used to explore relationships between hub genes and disease occurrence, development and prognosis of HCC, and the molecular mechanism of the main hub gene was probed using Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis. Results In total, 58 DEGs were obtained, of which 12 and 46 were up- and down-regulated, respectively. Three hub genes (CDKN3, CYP2C9 and LCAT) were identified and associated prognostic information was obtained. CDKN3 may be correlated with the occurrence, invasion, and recurrence of HCC. Genes closely related to changes in the CDKN3 hub gene were screened, and Kyoto Encyclopedia of Genes and Genomes (KEGGs) pathway analysis identified numerous cell cycle-related genes. Conclusion CDKN3 may affect the transformation of liver cirrhosis into HCC, and represents a new candidate molecular marker of the occurrence and progression of HCC.

Abstract
Background and aims. Cyclin-dependent kinase inhibitor 3 (CDKN3) has been found playing a varying role in carcinogenesis, but its biological function in esophageal squamous cell carcinoma (ESCC) is unclear. The aim of this study was to demonstrate the role of CDKN3 in ESCC. Materials and Methods: Real-time PCR and Western blot was performed in 15 pairs of ESCC tissues and adjacent normal esophageal tissues. Then cell proliferation ability, cloning ability, cell cycle status and migration and invasion ability were explored in CDKN3 overexpressed TE1 cell line and CDKN3 siRNA transfected TE1 and KYSE70 cell lines. Finally, cell cycle related proteins CyclinD1, CDK4, pAKT, P53, P21, and P27 were tested by Western blot. Results: mRNA level was higher in 11 ESCC tissues compared to adjacent normal tissues, and an increased protein expression was further detected in 8 of those 11 ESCC tissues. Functional assays showed that CDKN3 overexpression promoted ESCC cell proliferation, colony formation, migration and invasion, and facilitated G1/S transition. Opposite results were also got after transfected with CDKN3 siRNA. Cell cycle associated protein pAKT, CyclinD1, CDK4 and P27 were upregulated and P53, P21 and were downregulated under CDKN3 overexpression. All the protein levels were found changed in the opposite direction when CDKN3 expression was disturbed by siRNA. Conclusions: Our study suggested that CDKN3 acted as an oncogene in human ESCC and may accelerate the G1/S transition by affecting CyclinD-CDK4 complex via regulating pAKT-p53-p21 axis and p27 independent of AKT.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) represents a devastating malignancy characterized by high mortality, and notoriously problematic to diagnose. Recently, microRNAs (miRs) have been intensively investigated due to their potential usefulness from a tumor treatment perspective. AIMS The current study was aimed to investigate whether miR-494 influences epithelial-mesenchymal transition (EMT), tumor growth and metastasis of CCA. METHODS The regulatory miRNAs of WDHD1 in CCA expression chip were predicted, followed by determination of the miR-494 and WDHD1 expression in normal cholangiocyte tissues and CCA tissues. The related protein levels were determined. CCA cell migration, invasion, viability, and cell cycle distribution and the dosage-dependent effect of miR-494 on CCA cell growth were subsequently detected. Finally, tumorigenicity and lymph node metastasis (LNM) were measured. RESULTS Initially, miR-194 affected the CCA development via negatively regulating WDHD1 and miR-494 which were downregulated while WDHD1 was upregulated in CCA. In addition, miR-494 overexpression elevated E-cadherin expression while decreased expressions of WDHD1, N-cadherin, Vimentin, Snail, Twist and MMP-9. Finally, overexpressed miR-494 was observed to suppress EMT, cell viability, migration, invasion, arrest cell cycle progression, tumor formation, and LNM while accelerating cell apoptosis in vivo. CONCLUSION This study indicated that miR-494 overexpression suppresses EMT, tumor formation and LNM while promoting CCA cell apoptosis through inhibiting WDHD1 in CCA.

Abstract
Cyclin-dependent kinase inhibitor 3 (CDKN3) is proved to be associated with the progressing of many cancers. Whereas, its biological effects on prostate cancer (PC) are less understood. To investigate the functional mechanism of CDKN3 in PC, we examined the expression of CDKN3 in PC tissues and analyzed the disease free survival time of patients. We then transfected LNCaP and PC3 cells with siRNA-CDKN3 to silence CDKN3, and transfected 22RV1 and VCaP cells with full length CDKN3 cDNA for CDKN3 over-expression. Cell growth of these transfected cells were analyzed using CCK-8 assay. And transfected LNCaP and PC3 cells were further submitted to cell cycle, apoptosis, invasion and endogenous protein expression assays. We found that CDKN3 was highly expressed in PC and negatively correlated with disease relapse. And CDKN3 positively control the cell proliferation in prostate carcinoma cell lines. Knockdown of CDKN3 significantly promoted G1 phase arrest, elevated apoptosis rates, and suppressed cell invasion in both LNCaP and PC3 cells. Moreover, in vivo data showed that knockdown of CDKN3 expression dramatically inhibited the PC3 tumor growth in nude mouse model. Gene set enrichment analysis (GSEA) showed that cell cycle and DNA replication signaling were related with elevated CDKN3 expression. And results of western blot showed that the depletion of CDKN3 down-regulated the expression levels of cell cycle- and DNA replication-related proteins. In conclusion, our results highlight the importance of CDKN3 in PC and provide new insights into diagnostics and therapeutics of the PC.

Cress WD, Yu P, Wu J. Expression and alternative splicing of the cyclin-dependent kinase inhibitor-3 gene in human cancer. Int J Biochem Cell Biol 2017; 91:98-101. [PMID: 28504190 DOI: 10.1016/j.biocel.2017.05.013] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2017] [Revised: 04/27/2017] [Accepted: 05/06/2017] [Indexed: 01/04/2023]
Abstract
The cyclin-dependent kinase inhibitor-3 (CDKN3) gene encodes a dual-specificity protein tyrosine phosphatase that dephosphorylates CDK1/CDK2 and other proteins. CDKN3 is often overexpressed in human cancer, and this overexpression correlates with reduced survival in several types of cancer. CDKN3 transcript variants and mutations have also been reported. The mechanism of CDKN3 overexpression and the role of CDKN3 transcript variants in human cancer are not entirely clear. Here, we review the literature and provide additional data to assess the correlation of CDKN3 expression with patient survival. Besides the full-length CDKN3 encoding transcript and a major transcript that skips exon 2 express in normal and cancer cells, minor aberrant transcript variants have been reported. Aberrant CDKN3 transcripts were postulated to encode dominant-negative inhibitors of CDKN3 as an explanation for overexpression of the perceived tumor suppressor gene in human cancer. However, while CDKN3 is often overexpressed in human cancer, aberrant CDKN3 transcripts occur infrequently and at lower levels. CDKN3 mutations and copy number alternation are rare in human cancer, implying that neither loss of CDKN3 activity nor constitutive gain of CDKN3 expression offer an advantage to tumorigenesis. Recently, it was found that CDKN3 transcript and protein levels fluctuate during the cell cycle, peaking in mitosis. Given that rapidly growing tumors have more mitotic cells, the high level of mitotic CDKN3 expression is the most plausible mechanism of frequent CDKN3 overexpression in human cancer. This finding clarifies the mechanism of CDKN3 overexpression in human cancer and questions the view of CDKN3 as a tumor suppressor.

Abstract
Nasopharyngeal carcinoma (NPC) is a common malignancy of the head and neck that arises from the nasopharynx epithelium and is highly invasive. Cyclin-dependent kinase inhibitor 3 (CDKN3) belongs to the dual-specificity protein phosphatase family, which plays a key role in regulating cell division. Abnormal expression of CDKN3 has been found in numerous types of cancer. In the current study, we explored the possible role of CDKN3 in cell proliferation, ability to invade, and radiosensitivity in NPC cells. We reported that CDKN3 was upregulated and p27 was downregulated in NPC tissues and is associated with a worse prognosis for patients. In addition, downregulation of CDKN3 and upregulation of p27 decreased cell proliferation, induced cell cycle arrest, increased apoptosis, decreased cell invasion, and enhanced radiosensitivity. Silencing of p27 significantly inhibited the effects of the knockdown of CDKN3. Moreover, downregulation of CDKN3 and upregulation of p27 inhibited the increase in tumor volume and weight in implanted tumors, decreased the phosphorylation of Akt, and increased the expression of cleaved caspase 3 in tumors. CDKN3 expression was also inversely correlated with p27 expression in NPC patients. Knockdown of CDKN3 increased p27 expression. Silencing of p27 markedly inhibited the effects of CDKN3 on cell proliferation, cell cycle progression, apoptosis, invasion, and radiosensitivity. These results demonstrate that upregulation of p27 is involved in the knockdown of CDKN3-induced decrease in cell proliferation, increase in cell cycle arrest and apoptosis, decrease in invasion, and increase in radiosensitivity. The results demonstrate that the CDKN3/p27 axis may be a novel target in the treatment of NPC.

Abstract
Cyclin-dependent kinase inhibitor 3 (CDKN3) has been reported to promote tumorigenesis. Since it is unclear whether CDKN3 participates in the development of human gastric cancer, this study assessed the association between CDKN3 expression and cell biological function and demonstrated the clinical significance and prognosis of CDKN3 in human gastric cancer. In this study, we found that CDKN3 showed a high expression in 35 paired human gastric cancer tissues and was correlated with poor patient survival, AJCC clinical staging, and recurrence. Silencing of CDKN3 in human gastric cancer cells can significantly reduce proliferation, migration, invasion, and adhesion abilities. Also, silencing of CDKN3 in human gastric cancer cells can induce G0-G1 cell cycle arrest and apoptosis. Detection of cell cycle marker expression showed that CDKN3 knockdown promotes cell cycle arrest by decreasing the expression of CDK2, CDC25A, CCNB1, and CCNB2 in human gastric cancer cells. The results of this study will help elucidate the oncogene function of CDKN3 in human gastric cancer.

Abstract
BACKGROUND Ovarian cancer is the most common gynecological malignancy and constitutes the fifth leading cause of female cancer death. Some biological parameters have prognostic roles in patients with advanced ovarian cancer and their expression may contribute to tumor progression. The aim of this study was to investigate the potential prognostic value of SKP2, genes P27Kip1, K-ras, c-Myc, COX2 and HER2 genes expression in ovarian cancer. MATERIALS AND METHODS This study was performed on two hundred formalin fixed paraffin embedded ovarian cancer and normal adjacent tissues (NAT). Gene expression levels were assessed using real time PCR and Western blotting. RESULTS Elevated expression levels of SKP2, K-ras, c-Myc, HER2 and COX2 genes were observed in 61.5% (123/200), 92.5% (185/200), 74% (148/200), 96 % (192/200), 90% (180/200) and 78.5% (157/200) of cancer tissues, respectively. High expression of SKP2 and down-regulation of P27 was associated with advanced stages of cancer. CONCLUSIONS The association between high expression of c-Myc and SKP2 with low expression of P27 suggested that the Skp2-P27 pathway may play an important role in ovarian carcinogenesis. Reduced expression of P27 is associated with advanced stage of cancer and can be used as a biological marker in clinical routine assessment and management of women with advanced ovarian cancer.

Abstract
Background MicroRNAs (miRNAs) regulate gene expression by interfering translation or stability of target transcripts. This interplay between miRNA and their mRNA has been proposed as an important process in cancer development and progression. We have investigated molecular networks impacted by predicted mRNA targets of differentially expressed miRNAs in patients with clear cell renal cell carcinoma (ccRCC) diagnosed with or without metastasis. Material and Methods miRNA and mRNA microarray expression profiles derived from primary ccRCC from patients with (16 samples) or without diagnosed metastasis (22 samples) were used to identify anti-correlated miRNA-mRNA interaction in ccRCC. For this purpose, Ingenuity pathway analysis microRNA Target Filter, which enables prioritization of experimentally validated and predicted mRNA targets was used. By applying an expression pairing tool, the analysis was focused on targets exhibiting altered expression in our analysis, finding miRNAs and their target genes with opposite or same expression. The resulting identified interactions were revalidated by RT-qPCR in another cohort of ccRCC patients. A selection of the predicted miRNA-mRNA interactions was tested by functional analyses using miRNA knockdown and overexpression experiments in renal cancer cell lines. Results Among the significantly differentially expressed miRNAs, we have identified three miRNAs (miR-146a-5p, miR-128a-3p, and miR-17-5p) that were upregulated in primary tumors from patients without metastasis and downregulated in primary tumors from patients with metastasis. We have further identified mRNA targets, which expression were inversely correlated to these 3 miRNAs, and have been previously experimentally demonstrated in cancer setting in humans. Specifically, we showed that CXCL8/IL8, UHRF1, MCM10, and CDKN3 were downregulated and targeted by miR-146a-5p. The interaction between miR-146a-5p and their targets CXCL8 and UHRF1 was validated in cell culture experiments. Conclusions We identified novel target genes of dysregulated miRNAs, which are involved in the transition from primary RCC without metastases into tumors generating distant metastasis.
