Abstract
Objective: Nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS1) is highly expressed in some tumors, including hepatocellular carcinoma (HCC). However, its clinical significance in HCC prognosis is still unclear. The aim of this study was to explore the expression and prognostic value of NUCKS1 in HCC. Materials and Methods: Quantitative real-time polymerase chain reaction was used to detect relative expression of NUCKS1 mRNA in HCC tissues and corresponding adjacent normal tissues. The relationship between NUCKS1 expression and clinical characteristics of patients was analyzed by χ2 test. Kaplan-Meier method and Cox regression analysis were applied to estimate prognostic value of NUCKS1 in HCC. Results: Compared with normal ones, the expression of NUCKS1 mRNA was significantly upregulated in HCC tissues (p < 0.001). Besides, NUCKS1 expression was closely associated with tumor differentiation, tumor node metastasis stage, vascular invasion, and metastasis (p < 0.05). Kaplan-Meier analysis revealed that overall survival was obviously longer in HCC patients with low expression of NUCKS1 than those with high NUCKS1 expression (log rank test, p = 0.001). NUCKS1 might be an independent prognostic factor for HCC patients (HR = 1.905, 95% CI = 1.106-3.283, p = 0.020). Conclusions: NUCKS1 may be correlated with the progression of HCC and serve as a potential predictive factor for the prognosis of this disease.

NUCKS1 is a highly modified, chromatin-associated protein involved in a diverse set of biological and pathophysiological processes. Biochem J 2022; 479:1205-1220. [PMID: 35695515 PMCID: PMC10016235 DOI: 10.1042/bcj20220075] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 05/17/2022] [Accepted: 05/26/2022] [Indexed: 11/17/2022]
Abstract
The Nuclear Casein and Cyclin-dependent Kinase Substrate 1 (NUCKS1) protein is highly conserved in vertebrates, predominantly localized to the nucleus and one of the most heavily modified proteins in the human proteome. NUCKS1 expression is high in stem cells and the brain, developmentally regulated in mice and associated with several diverse malignancies in humans, including cancer, metabolic syndrome and Parkinson's disease. NUCKS1 function has been linked to modulating chromatin architecture and transcription, DNA repair and cell cycle regulation. In this review, we summarize and discuss the published information on NUCKS1 and highlight the questions that remain to be addressed to better understand the complex biology of this multifaceted protein.

Abstract
To evaluate the clinicopathologic features and survival analysis of NUCKS1 expression in human lung adenocarcinoma (LA), we used bioinformatic methods to obtain NUCKS1 gene status and correlated it with prognosis in LA. We compared NUCKS1 expression in 70 samples of LA with intrinsically normal lung alveoli (NLA) by immunohistochemistry, and analyzed their clinicopathologic features. NUCKS1 was overexpressed in LA components(LACs) relative to NLA, and was significantly correlated to patient with 5-year disease-free survival (DFS) and overall survival(OS). Elevated NUCKS1 expression in LACs was shown to be an independent prognostic indicator for OS and a biomarker in LA.

Abstract
Background Nuclear casein kinase and cyclin-dependent kinase substrate (NUCKS), a novel gene first reported in 2001, is a member of the high mobility group (HMG) family. Although very little is known regarding the biological roles of NUCKS, emerging clinical evidence suggests that the NUCKS protein can be used as a biomarker and therapeutic target in various human ailments, including several types of cancer. Methods We first assessed the potential correlation between NUCKS expression and gastric cancer prognosis. Then functional experiments were conducted to evaluate the effects of NUCKS in cell proliferation, cell cycle, apoptosis and autophagy. Finally, the roles of NUCKS on gastric cancer were examined in vivo. Results We found that NUCKS was overexpressed in gastric cancer patients with poor prognosis. Through manipulating NUCKS expression, it was observed to be positively associated with cell proliferation in vitro and in vivo. NUCKS knockdown could induce cell cycle arrest and apoptosis. Then further investigation indicated that NUCKS knockdown could also significantly induce a marked increase in autophagy though the mTOR-Beclin1 pathway, which could be was rescued by NUCKS restoration. Moreover, silencing Beclin1 in NUCKS knockdown cells or adding rapamycin in NUCKS-overexpressed cells also confirmed these results. Conclusions Our findings revealed that NUCKS functions as an oncogene and an inhibitor of autophagy in gastric cancer. Thus, the downregulation or inhibition of NUCKS may be a potential therapeutic strategy for gastric cancer.

Ki-67/MKI67 as a Predictive Biomarker for Clinical Outcome in Gastric Cancer Patients: an Updated Meta-analysis and Systematic Review involving 53 Studies and 7078 Patients. J Cancer 2019; 10:5339-5354.

Abstract
Gastric cancer (GC) threatens human health worldwide and we performed this meta-analysis to evaluate the clinical value of Ki-67/MKI67 in patients with GC. The combined hazard ratio (HR), odds ratio (OR) and 95% confidence interval (95% CI) were calculated to assess the relationships of Ki-67/MKI67 expression with prognoses and clinicopathological characteristics. Genes co-expressed with MKI67 were collected for Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and protein-protein interaction (PPI) network analyses. In total, 53 studies with 7078 patients were included in this study. The pooled HRs indicated that an elevated expression of Ki-67/MKI67 predicted an unfavorable overall survival (HR: 1.54, 95% CI: 1.33-1.78, P<0.0001) and disease-free survival (HR: 2.28, 95% CI: 1.43-3.64, P<0.0001) in GC patients. Additionally, in patients with advanced GC, a high Ki-67/MKI67 expression was also significantly connected with OS (HR: 1.37, 95% CI: 1.18-1.60, P<0.0001). The combined ORs showed that Ki-67/MKI67 expression was related to TNM stage (stage III/IV versus stage I/II: OR=1.93, 95% CI=1.34-2.78, P<0.0001), tumor differentiation (poor versus well/moderate: OR=1.94, 95% CI=1.32-2.85, P=0.001), lymph node metastasis (yes versus no: OR=1.67, 95% CI=1.23-2.25, P=0.001), distant metastasis (yes versus no: OR=1.67, 95% CI=1.24-2.26, P=0.001) and tumor invasion depth (T3/T4 versus Tis/T1/T2: OR=1.98, 95% CI=1.60-2.44, P<0.0001). The results of GO, KEGG pathway and PPI network analyses indicated that Ki-67/MKI67 may be involved in the development of GC via influencing P53 signaling pathway. Ki-67/MKI67 could be a potential indicator to predict the prognosis of patients with GC and identify high-risk cases. Detecting Ki-67/MKI67 expression in clinic may be helpful in optimizing individual treatment and further improving the survival expectancy of patients with GC.

Abstract
BACKGROUND The prognostic value and clinicopathologic significance of Ki-67 expression in gastric cancer patients was controversial. This meta-analysis was performed to clarify the prognostic value and clinicopathologic significance of Ki-67 expression in gastric cancer patients. MATERIALS AND METHODS Several electronic databases were searched for eligible studies. The pooled odds ratio (OR), hazard ratios (HR) and 95% confidence interval(CI) were calculated to explore the prognostic value and clinicopathologic significance of Ki-67 expression for disease free survival and overall survival. RESULTS Totally 5600 gastric cancer patients from 29 studies were included in this study. High Ki-67 expression was significantly related with Lauren's classification (OR = 1.70; P = 0.001; 95%CI: 1.40-2.06) and tumor size(OR = 1.54; P = 0.006; 95%CI: 1.14-2.09). However, high Ki-67 expression was not significantly associated with lymph node metastasis (OR = 1.37; P = 0.138; 95% CI: 0.90-2.08) , tumor stage (OR = 1.31; P = 0.296; 95% CI: 0.79-2.16) and tumor differentiation (OR = 1.03; P = 0.839; 95% CI: 0.78-1.35). The pooled HRs were 1.87(P = 0.001; 95% CI 1.30-2.69) for disease free survival and 1.23(P = 0.005; 95% CI 1.06-1.42) for overall survival. CONCLUSIONS High Ki-67 expression may serve as a predictive biomarker for poor prognosis in gastric cancer patients. Stratification by Ki-67 expression may be a consideration for selection of therapeutic regimen and integrated managements.

Nucks1 synergizes with Trp53 to promote radiation lymphomagenesis in mice. Oncotarget 2018; 7:61874-61889.

Abstract
NUCKS1 is a 27 kD vertebrate-specific protein, with a role in the DNA damage response. Here, we show that after 4 Gy total-body X-irradiation, Trp53+/− Nucks1+/− mice more rapidly developed tumors, particularly thymic lymphoma (TL), than Trp53+/− mice. TLs in both cohorts showed loss of heterozygosity (LOH) of the Trp53+ allele in essentially all cases. In contrast, LOH of the Nucks1+ allele was rare. Nucks1 expression correlated well with Nucks1 gene dosage in normal thymi, but was increased in the majority of TLs from Trp53+/− Nucks1+/− mice, suggesting that elevated Nucks1 message may be associated with progression towards malignancy in vivo. Trp53+/− Nucks1+/− mice frequently succumbed to CD4- CD8- TLs harboring translocations involving Igh but not Tcra/d, indicating TLs in Trp53+/− Nucks1+/− mice mostly originated prior to the double positive stage and at earlier lineage than TLs in Trp53+/- mice. Monoclonal rearrangements at Tcrb were more prevalent in TLs from Trp53+/− Nucks1+/− mice, as was infiltration of primary TL cells to distant organs (liver, kidney and spleen). We propose that, in the context of Trp53 deficiency, wild type levels of Nucks1 are required to suppress radiation-induced TL, likely through the role of the NUCKS1 protein in the DNA damage response.

Abstract
Nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS1) is a 27 kD chromosomal, highly conserved, and vertebrate-specific protein. NUCKS1 gene encodes a nuclear protein and the conserved regions of NUCKS1 contain several consensus phosphorylation sites for casein kinase II (CK2) and cyclin-dependent kinases (Cdk) and a basic DNA-binding domain. NUCKS1 is similar to the high mobility group (HMG) family which dominates chromatin remodeling and regulates gene transcription. Meanwhile, NUCKS1 is a RAD51 associated protein 1 (RAD51AP1) paralog that is significant for homologous recombination (HR) and genome stability and also a transcriptional regulator of the insulin signaling components. NUCKS1 plays an important role in DNA damage response and metabolism, participates in inflammatory immune response, and correlates with microRNA. Although there is still not enough functional information on NUCKS1, evidences suggest that NUCKS1 can be used as the biomarker of several cancers. This review summarizes the latest research on NUCKS1 about its susceptibility in diseases, expression levels, and regulatory mechanisms as well as the possible functions in reference to diseases.

Abstract
NUCKS (nuclear, casein kinase, and cyclin-dependent kinase substrate) is implicated in the tumorigenesis of several human malignancies, but its role in ovarian cancer remains unknown. We aim to investigate NUCKS expression and its clinical significance in ovarian cancer. The messenger RNA expression of NUCKS was determined in normal and malignant ovarian tissues using quantitative polymerase chain reaction assay. Immunohistochemistry was applied to detect the status of NUCKS protein expression in 121 ovarian cancer tissues. NUCKS protein high expression was detected in 52 (43.0%) of 121 patients. NUCKS messenger RNA expression was gradually upregulated in non-metastatic ovarian cancers ( n = 20), metastatic ovarian cancers ( n = 20), and its matched metastatic lesions ( n = 20) in comparison with that in normal ovarian tissues ( n = 10; p < 0.05). Elevated expression of NUCKS in ovarian cancer was associated significantly with the Federation of Gynecology and Obstetrics stage ( p = 0.037), histological grade ( p = 0.003), residual disease ( p = 0.013), lymph node metastasis ( p = 0.002), response to chemotherapy ( p < 0.001), and recurrence ( p = 0.013). In the multivariate Cox analysis, NUCKS expression was an independent prognostic marker for overall survival and disease-free survival in ovarian cancer with p values of <0.001 for both. Especially, NUCKS overexpression had prognostic potential for overall survival and disease-free survival ( p < 0.001 for both) in advanced ovarian cancers and only for disease-free survival in early ovarian cancers ( p = 0.017). Our data suggest that NUCKS overexpression may contribute to progression and poor prognosis in ovarian cancer especially in advanced ovarian cancer.

Abstract
The prognostic significance of Ki-67 in patients with gastric cancer (GC) remains controversial. The aim of our meta-analysis is to evaluate its association with clinicopathological characteristics and prognostic value in patients with GC. PubMed, EMBASE, and Web of Science were systematically searched up to May 2017. Twenty-two studies including 3,825 patients with GC were analyzed. The meta-analysis indicated that the incidence difference of Ki-67 expression in GC patients was significant when comparing the older group to younger group (odds ratio [OR] =1.44, 95% confidence interval [CI] 1.19, 1.75), lymph node positive group to negative group (OR =1.49, 95% CI 1.20, 1.84), the large size tumor group to the small size tumor group (OR =1.27, 95% CI 1.24, 1.68) and the TNM stage III+IV group to TNM stage I+II group (OR =2.28, 95% CI 1.66, 3.12). However, no statistical differences existed in gender. The detection of Ki-67 significantly correlated with the overall survival of patients (hazard ratio =1.51, 95% CI 1.31, 1.72). Our study suggested that Ki-67 overexpression was associated with poor prognosis in GC patients. Ki-67 positive rates may be associated with age, lymph node metastasis, tumor size, and TNM staging system in GC patients.

Grundt K, Thiede B, Østvold AC. Identification of kinases phosphorylating 13 sites in the nuclear, DNA-binding protein NUCKS. BIOCHIMICA ET BIOPHYSICA ACTA-PROTEINS AND PROTEOMICS 2016; 1865:359-369. [PMID: 28011258 DOI: 10.1016/j.bbapap.2016.12.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2016] [Revised: 12/05/2016] [Accepted: 12/19/2016] [Indexed: 12/27/2022]
Abstract
NUCKS is a vertebrate specific, nuclear and DNA-binding phospho protein. The protein is highly expressed in rapidly dividing cells, and is overexpressed in a number of cancer tissues. The phosphorylation of NUCKS is cell cycle and DNA-damage regulated, but little is known about the responsible kinases. By utilizing in vitro and in vivo phosphorylation assays using isolated NUCKS as well as synthetic NUCKS-derived peptides in combination with mass spectrometry, phosphopeptide mapping, phosphphoamino acid analyses, phosphospecific antibodies and the use of specific kinase inhibitors, we found that NUCKS is phosphorylated on 11 sites by CK2. At least 7 of the CK2 sites are phosphorylated in vivo. We also found that NUCKS is phosphorylated on two sites by ATM kinase and DNA-PK in vitro, and is phosphorylated in vivo by ATM kinase in γ-irradiated cells. All together, we identified three kinases phosphorylating 13 out of 39 in vivo phosphorylated sites in mammalian NUCKS. The identification of CK2 and PIKK kinases as kinases phosphorylating NUCKS in vivo provide further evidence for the involvement of NUCKS in cell cycle control and DNA repair.

Parplys AC, Zhao W, Sharma N, Groesser T, Liang F, Maranon DG, Leung SG, Grundt K, Dray E, Idate R, Østvold AC, Schild D, Sung P, Wiese C. NUCKS1 is a novel RAD51AP1 paralog important for homologous recombination and genome stability. Nucleic Acids Res 2015; 43:9817-34. [PMID: 26323318 PMCID: PMC4787752 DOI: 10.1093/nar/gkv859] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2015] [Revised: 07/09/2015] [Accepted: 08/17/2015] [Indexed: 01/20/2023] Open
Abstract
NUCKS1 (nuclear casein kinase and cyclin-dependent kinase substrate 1) is a 27 kD chromosomal, vertebrate-specific protein, for which limited functional data exist. Here, we demonstrate that NUCKS1 shares extensive sequence homology with RAD51AP1 (RAD51 associated protein 1), suggesting that these two proteins are paralogs. Similar to the phenotypic effects of RAD51AP1 knockdown, we find that depletion of NUCKS1 in human cells impairs DNA repair by homologous recombination (HR) and chromosome stability. Depletion of NUCKS1 also results in greatly increased cellular sensitivity to mitomycin C (MMC), and in increased levels of spontaneous and MMC-induced chromatid breaks. NUCKS1 is critical to maintaining wild type HR capacity, and, as observed for a number of proteins involved in the HR pathway, functional loss of NUCKS1 leads to a slow down in DNA replication fork progression with a concomitant increase in the utilization of new replication origins. Interestingly, recombinant NUCKS1 shares the same DNA binding preference as RAD51AP1, but binds to DNA with reduced affinity when compared to RAD51AP1. Our results show that NUCKS1 is a chromatin-associated protein with a role in the DNA damage response and in HR, a DNA repair pathway critical for tumor suppression.

Abstract
Nuclear, casein kinase and cyclin-dependent kinase substrate (NUCKS), a protein similar to the HMG (high-mobility group) protein family, is one of the most modified proteins in the mammalian proteome. Although very little is known about the biological roles of NUCKS, emerging clinical evidence suggests that this protein can be a biomarker and therapeutic target in various human ailments, including several types of cancer. An inverse correlation between NUCKS protein levels and body mass index in humans has also been observed. Depletion of NUCKS in mice has been reported to lead to obesity and impaired glucose homoeostasis. Genome-wide genomic and proteomic approaches have revealed that NUCKS is a chromatin regulator that affects transcription. The time is now ripe for further understanding of the role of this novel biomarker of cancer and the metabolic syndrome, and how its sundry modifications can affect its function. Such studies could reveal how NUCKS could be a link between physiological cues and human ailments.
