The ZNF76 rs10947540 polymorphism associated with systemic lupus erythematosus risk in Chinese populations. Sci Rep 2021; 11:5186. [PMID: 33664275 PMCID: PMC7933287 DOI: 10.1038/s41598-021-84236-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Accepted: 02/02/2021] [Indexed: 12/13/2022] Open
Abstract
Systemic lupus erythematosus (SLE) is a typical autoimmune disease with a strong genetic disposition. Genetic studies have revealed that single-nucleotide polymorphisms (SNPs) in zinc finger protein (ZNF)-coding genes are associated with susceptibility to autoimmune diseases, including SLE. The objective of the current study was to evaluate the correlation between ZNF76 gene polymorphisms and SLE risk in Chinese populations. A total of 2801 individuals (1493 cases and 1308 controls) of Chinese Han origin were included in this two-stage genetic association study. The expression of ZNF76 was evaluated, and integrated bioinformatic analysis was also conducted. The results showed that 28 SNPs were associated with SLE susceptibility in the GWAS cohort, and the association of rs10947540 was successfully replicated in the independent replication cohort (Preplication = 1.60 × 10-2, OR 1.19, 95% CI 1.03-1.37). After meta-analysis, the association between rs10947540 and SLE was pronounced (Pmeta = 9.62 × 10-6, OR 1.29, 95% CI 1.15-1.44). Stratified analysis suggested that ZNF76 rs10947540 C carriers were more likely to develop relatively high levels of serum creatinine (Scr) than noncarriers (CC + CT vs. TT, p = 9.94 × 10-4). The bioinformatic analysis revealed that ZNF76 rs10947540 was annotated as an eQTL and that rs10947540 was correlated with decreased expression of ZNF76. Remarkably, significantly reduced expression of ZNF76 was confirmed by expression data from both our laboratory and an array-based expression database. Taken together, these results suggest that ZNF76 rs10947540 is a possible susceptibility factor associated with SLE susceptibility. The mechanism underlying the relationship between ZNF76 and SLE pathogenesis still requires further investigation.

Abstract
MicroRNAs (miRNAs) as the regulatory short noncoding RNAs are involved in a wide array of cellular and molecular processes. They negatively regulate gene expression and their dysfunction is correlated with cancer development through modulation of multiple signaling pathways. Therefore, these molecules could be considered as novel biomarkers and therapeutic targets for more effective management of human cancers. Recent studies have demonstrated that the miR-181 family is dysregulated in various tumor tissues and plays a pivotal role in carcinogenesis. They have been shown to act as oncomirs or tumor suppressors considering their mRNA targets and to be involved in cell proliferation, apoptosis, autophagy, angiogenesis and drug resistance. Additionally, these miRNAs have been demonstrated to exert their regulatory effects through modulating multiple signaling pathways including PI3K/AKT, MAPK, TGF-b, Wnt, NF-κB, Notch pathways. Given that, in this review, we briefly summarise the recent studies that have focused on the roles of miRNA-181 family as the multifunctional miRNAs in tumorigenesis and cancer development. These miRNAs may serve as diagnostic and prognostic biomarkers or therapeutic targets in human cancer gene therapy.

Abstract
Ulcerative colitis is an idiopathic, chronic and relapsing inflammatory bowel disease, which elicits the risk of colorectal cancer, the third most common malignancy in humans. It has been known for a long time that oxidative stress is a major pathogenic factor in the inflamed tissue that can pave the way towards DNA damage and carcinogenesis. However, the DNA damage produced due to oxidative stress in the inflamed tissue is not limited to the local site but extends globally, thereby augmenting the risk of global carcinogenesis. Targeting oxidative stress may provide an exciting avenue to combat inflammation-associated local as well as global DNA damage and the subsequent carcinogenesis. The present review portrays the role of oxidative stress in the pathogenesis of ulcerative colitis and the associated local as well as global DNA damage, which may lead to carcinogenesis.

Abstract
MicroRNAs (miRNAs) are short noncoding RNAs that act as post-transcriptional regulators. The low complementarity required between the sequences of a miRNA and its target mRNA enables a single miRNA to act on a large range of targets. Thus miRNAs have an intersecting complex effect that spans a multiplicity of pathways and processes. In this review, the different roles of a vital miRNA, miR-181a, in physiological and pathological developments are collated in an attempt to highlight the intersections of such processes and to show how the deregulation of miR-181a could in one context drive malignancy, whereas in another it can lead to autoimmunity. Such deregulation could be related to the faulty levels of one of its own targets, p53, which was recently reported to control an array of miRNAs, one of which is miR-181a. This sheds light on a hidden loop of chaos behind chronic diseases such as autoimmunity and cancer.

Abstract
AIM: To investigate the role of p53 antibodies (p53Abs), metallothioneins (MTs) and oxidative stress markers in the early detection of dysplasia in chronic ulcerative colitis (UC).
METHODS: The study included 30 UC patients, 15 without dysplasia (group II) and 15 with dysplasia (group III), in addition to 15 healthy volunteers (group I, control subjects). The enzyme-linked immunosorbent assay technique was used to measure serum p53Abs and MTs, while advanced oxidation protein products (AOPPs), and reduced glutathione (GSH) levels were measured by spectrophotometric method in all subjects.
RESULTS: In group II and group III compared to group I, there were significant increases in serum levels of AOPPs (145.94 ± 29.86 μmol/L and 192.21 ± 46.71 μmol/L vs 128.95 ± 3.06 μmol/L, P < 0.002 and P < 0.001, respectively), MTs (8.18 ± 0.35 μg/mL and 9.20 ± 0.58 μg/mL vs 6.12 ± 0.25 μg/mL, P < 0.05 and P < 0.05, respectively), and p53Abs (20.19 ± 3.20 U/mL and 34.66 ± 1.34 U/mL vs 9.42 ± 1.64 U/mL, P < 0.001 and P < 0.001, respectively). There were significantly higher levels of AOPPs (P < 0.05) and p53Abs (P < 0.001) in UC patients with dysplasia compared to those without dysplasia, while MTs showed no significant difference between the 2 groups (P > 0.096). In contrast, GSH levels showed a significant decrease in both patients’ groups (1.87 ± 0.02 μmol/mL and 1.37 ± 0.09 μmol/mL vs 2.49 ± 0.10 μmol/mL, P < 0.05 and P < 0.05 in groups II and III, respectively) compared with group I, and the levels were significantly lower in group III than group II (P < 0.05). There was a positive correlation between AOPPs and both MTs (r = 0.678, P < 0.001) and p53Abs (r = 0.547, P < 0.001), and also between p53Abs and MTs (r = 0.739, P < 0.001). There was a negative correlation between AOPPs and GSH (r = -0.385, P < 0.001), and also between GSH and both MTs (r = -0.662, P < 0.001) and p53Abs (r = -0.923, P < 0.001).
CONCLUSION: Oxidative stress and oxidative cellular damage play an important role in the pathogenesis of chronic UC and the associated carcinogenetic process. p53Abs levels could help in early detection of dysplasia in these conditions.

Abstract
The p53 tumour suppressor is the central regulator of apoptosis. Previously, the functional TP53 Arg72Pro polymorphism was found to be associated with systemic lupus erythematosus (SLE) in Koreans but not Spaniards. MDM2 is the major negative regulator of p53. An intronic polymorphism in MDM2, the SNP309, attenuates p53 activity and is associated with accelerated tumour development in premenopausal women. Polymorphic variation in MDM2 has never been studied in SLE. The aim of this study is to further assess the contribution of p53-pathway genetic variation to SLE by testing the association of the TP53 Arg72Pro polymorphism and the MDM2 SNP309 with SLE in a well-characterised and ethnically diverse cohort of patients with both childhood- and adult-onset SLE (n = 314). No association was found between the TP53 Arg72Pro polymorphism and SLE in patients of European descent, Asian descent or in African Americans, nor was an association found between the MDM2 SNP309 and SLE in patients of European descent or in African Americans. In addition, there was no correlation between either variant and early-onset disease or nephritis, an index of severe disease. It is concluded that neither the TP53 Arg72Pro polymorphism nor the MDM2 SNP309 contributes significantly to either susceptibility or disease severity in SLE.

Abstract
Dermatomyositis/polymyositis (DM/PM), which is often accompanied by various immunological abnormalities, was reported to be associated with an increased incidence of malignancies. In this study, we analyzed serum levels of anti-p53 antibody (anti-p53 Ab) in DM/PM patients and in normal controls. Serum levels of anti-p53 Abs were significantly higher in DM/PM patients than those in healthy controls. However, there was no significant difference between serum levels in patients with malignancies and those in patients without malignancies. Anti-p53 Abs were positive in 13% (4 out of 31) of the DM/PM patients. Of these four patients, only one had an internal malignancy. Immunoglobulin G levels were significantly higher in patients positive for anti-p53 Ab than those who were not. These results seemed to suggest that the presence of anti-p53 Abs in DM/PM patients is due to immunological abnormalities in this disease.

Abstract
BACKGROUND P53 is a key protein which controls cell cycle arrest and apoptosis in response to DNA damage. Auto-antibodies against p53 have been detected in some cancer patients and also in patients with autoimmune diseases. In these patients, the main cause of anti-p53 antibody occurrence was considered to be increased intracellular p53 protein in cancer cells and autoreactive lymphocytes, respectively. Intracellular p53 also increases with cardiomyocyte apoptosis during heart failure and autoreactive lymphocytes play a role in the course of idiopathic dilated cardiomyopathy (IDC) and ischemic cardiomyopathy (ICM). Based on these observations, we hypothesized that anti-p53 antibody response may also occur in patients with heart failure due to ICM and IDC. AIM The aim of this study was to evaluate anti-p53 antibodies in the serum of patients with heart failure due to IDC and ICM. METHODS 70 eligible patients with heart failure and severe left ventricular systolic dysfunction (mean fractional shortening 12.03 +/- 3.93%) were included in the study. The aetiology of heart failure was IDC in 26 patients and ICM in 44 patients, according to the angiographic and echocardiographic findings. RESULTS Anti-p53 antibodies were not detected in any of the patients. CONCLUSION Anti-p53 antibodies do not occur in patients with heart failure due to IDC and ICM, possible explanations are discussed in the text.

Abstract
During tumor progression, the accumulation in genetic alterations is a fundamental characteristic of malignant cells. p53 gene is frequently mutated in human tumor. Cellular accumulation of p53 protein can initiate an immune response with generation of circulating anti-p53 antibodies. Patients with ulcerative colitis have an increased risk of developing colorectal neoplasm and, among the different genes involved in carcinogenesis, p53 may play a key role. Sera and tissues from 97 patients (M = 53, F = 44) affected with ulcerative colitis (UC) were collected. Serum anti-p53 antibodies (p53Abs) were detected in duplicate with ELISA method. Serum p53Abs were detectable in 9.3% (9/97) of patients affected with UC. In these patients, the titer of p53Ab ranged between 3.1 and 14.9 U/mL (mean, 6.6 U/mL; SD, 4.64). Serum p53Abs were undetectable in control group. With an immunoluminometric assay for the quantitative determination of p53, we found 9/97 positive samples (> or = 0.69 mg/mg of total proteins). In contrast, the samples of the remaining 89 patients were found negative (< or = 0.30 mg/mg of total proteins). All patients that were positive for anti-p53 antibodies were also positive with p53 protein accumulation in the tissue of colonic biopsies. In UC, follow-up with colonoscopy has several advantages. The colonoscopy is not well accepted by patients, and poor patient observance has the potential to seriously devalue the technique as a screening tool, despite practical considerations of competence within endoscopy service. Serological detection of p53Abs by enzyme-linked immunosorbent assay (ELISA) is easy to perform, does not require tumor specimen, can be performed in a routine diagnostic procedure, may be used in clinical practice, and could facilitate physicians in patient monitoring. We suggest that serum p53Abs assessment, indirect marker for p53 gene mutations, and abnormally high p53 protein levels could be considered to have a potential for use as a complementary test to improve surveillance program performance.
