Abstract
Abstract
Background
The like-Smith (LSM) family is a group of RNA-binding proteins involved in RNA metabolism. However, their involvement in tumors, particularly skin cutaneous melanoma (SKCM), is not fully understood. In this study, we focused on the expression profiles and prognostic values of the LSM family in SKCM.
Methods
Raw data were downloaded from The Cancer Genome Atlas. The expression profile and prognostic value of LSM genes in SKCM were explored using the GEPIA, cBioPortal, and HPA databases. Protein–protein and gene–gene interaction analyses were performed using STRING and GeneMANIA. Enrichment and Cox regression analysis were conducted using R software. The TISIDB database was used to explore the relationship between LSMs and immunomodulators. Receiver operating characteristic curves and nomogram models were constructed to validate prognostic values.
Results
mRNA and protein expression levels of LSM2, LSM4, and LSM12 were significantly elevated in SKCM. The upregulated mRNA expression of LSM2 (p = 0.0013) and LSM4 (p = 0.0043) was significantly correlated with poor overall survival in patients with SKCM, whereas only LSM2 (p = 0.049) overexpression was markedly associated with worse disease-free survival. LSM2 overexpression was an independent risk factor (p = 0.013) and was confirmed to have a high prognostic value in SKCM using the receiver operating characteristic curve (AUC = 0.942) and nomogram models. All LSM genes were identified as genomic mutations, whereas alteration of LSM2 (p = 0.0153) significantly affected the overall survival in patients with SKCM. Significant correlations were observed between LSM family expression, immune cell infiltration, and immunomodulator. Furthermore, function and pathway enrichment analysis showed that the LSM family was mainly RNA binding proteins and involved in RNA splicing and degradation.
Conclusion
Expression profiles and prognostic values of LSM in SKCM were inconsistent. Among the LSM family, only LSM2 may serve as a potential poor prognosticator and immunotherapeutic target of SKCM.

Abstract
Previous studies have indicated that Zinc ribbon domain-containing 1 (ZNRD1) is attributed to the carcinogenesis of human tumors. However, the role of ZNRD1 and its regulation in hepatocellular carcinoma (HCC) are still largely unclear. In this study, we examined the expression profiles of ZNRD1 in HCC tissues by immunohistochemistry (IHC) and publicly datasets analysis. In vitro and in vivo experiments were conducted to identify the function of ZNRD1 in HCC. In addition, miRNA potentially targeting ZNRD1 was predicted by bioinformatics analysis and further verified via in vitro experiments. Our results revealed that ZNRD1 was frequently upregulated in HCC tissues compared with that in nontumor tissues. High ZNRD1 expression in HCC tissues was positively associated with advanced tumor stage and poor prognosis. Function experiments showed that knockdown of ZNRD1 inhibited cell growth and invasion in vitro, and suppressed tumor development in vivo. Moreover, ZNRD1 promoted the activation of Wnt/β-catenin signaling pathway in HCC. Importantly, miR-26b directly inhibited the transcription activity of ZNRD1. Overexpression of ZNRD1 dramatically abolished the inhibitory effects of miR-26b on HCC cells. Taken together, our results uncover a novel mechanistic role for miR-26b/ZNRD1 axis in HCC, proposing ZNRD1 inhibition as a potent therapeutic strategy for hepatocellular carcinoma.

Abstract
Genetic variants in zinc ribbon domain-containing 1 antisense RNA 1 (ZNRD1-AS1) have been reported to be associated with development of hepatocellular carcinoma (HCC). We sought to determine the influences of ZNRD1-AS1 polymorphisms and their interactions with Hepatitis B virus (HBV) genotypes on the risk of HCC. In this study, we conducted a large population case-control study with 1,507 HBV-related HCC cases and 1,560 HBV persistent carriers. Three single-nucleotide polymorphisms (SNPs) in ZNRD1-AS1 (rs3757328, rs6940552 and rs9261204) were genotyped using a TaqMan allelic discrimination assay, and the HBV genotypes were identified by multiplex PCR. We found consistently significant associations between the ZNRD1-AS1 rs6940552 and rs9261204 SNPs with an increased risk of HCC (additive genetic model: adjusted OR = 1.16, 95% CI = 1.03-1.32 for rs6940552; adjusted OR =1.20, 95% CI = 1.06-1.35 for rs9261204) and found a borderline association between rs3757328 and HCC risk. Besides, we observed a dose-dependent relationship between increasing numbers of variant alleles of the SNPs and HCC risk (P for trend <0.001). Moreover, we observed a stronger combined effect of the three SNPs on HCC risk among the subjects infected with non-B genotype HBV (adjusted OR = 1.26, 95% CI = 1.05-1.50) compared with HBV B-related genotypes (adjusted OR = 0.89, 95% CI = 0.69-1.15; P= 0.029 for heterogeneity test). We also found that a multiplicative interaction between the variant alleles and the HBV genotype significantly affected HCC susceptibility (P = 0.030). Together, these results indicate that ZNRD1-AS1 may influence HCC risk accompanied by HBV genotypes.

Abstract
Long noncoding RNAs (IncRNAs), involved in cancer biology, contributing to essential cancer cell functions such as proliferation, invasion, and metastasis, have received increasing attention recently. Human Zinc ribbon domain containing 1 (ZNRD1) has been confirmed to be involved in carcinogenesis and development of multiple cancers. ZNRD1-AS1, a lncRNA in the upstream region of ZNRD1 which could down-regulate the expression of ZNRD1, has been identified as a possible component in carcinogenesis. The underlying relations of ZNRD1-AS1 with lung cancer development and metastasis remain obscure. In current study, we first evaluated the expression ZNRD1-AS1 and ZNRD1 among lung cancer tissues and corresponding normal tissues, which showed higher expression of ZNRD1-AS1 and lower expression of ZNRD1. To reveal the underlying mechanisms, we then investigated the associations between ZNRD1 eQTLs SNPs in ZNRD1-AS1 and risk of lung cancer in Han Chinese populations. G allele of SNP rs9261204 was significantly associated with an increased risk of lung cancer when compared with A allele (OR: 1.45; 95% CI: 1.19–1.75; P = 1.06 × 10−4). A weaker, but similar effect was also observed in bladder cancer. SNP rs3757328 was also associated with increased risk of lung cancer (OR: 1.34; 95% CI: 1.07–1.67; P = 0.011). Our findings first confirmed the contribution of LncRNA ZNRD1-AS1 to the development of lung cancer in Asian population.

Abstract
The downregulation of zinc ribbon domain-containing 1 (ZNRD1) protein was recently found to partially reverse the resistance of human leukemia cells toward chemical therapeutic drugs. Therefore, the ZNRD1 protein might be involved in the process of DNA damage and repair. To explore the possible protective effects of ZNRD1 on DNA damage induced by ultraviolet (UV)-C irradiation in human esophageal squamous cancer cell line EC109, we designed and transfected a expression vector into EC109 cells, and established an overexpression cell line. The single-cell gel electrophoresis (comet assay) was used to investigate the DNA damage and repair in UV-C-irradiated control and transfected cells. It was found that the ZNRD1-expressing cells exhibited a significant enhanced DNA repair capacity. Moreover, the overexpression of ZNRD1 could upregulate the expression of excision repair cross-complementing 1 (ERCC1) gene. Collectively, these findings suggested that ZNRD1 might play an important role in the process of DNA damage and repair by regulating the expression of ERCC1.

Abstract
Gastric cancer is the second leading cause of cancer mortality worldwide. The major cause of treatment failure for gastric cancer is the development of multidrug resistance (MDR) to chemotherapy, which is currently one of the primary treatment options. Recently, research into the MDR of gastric cancer has revealed that, in addition to the classical ATP-binding cassette transporters, such as P-glycoprotein (P-gp) and MDR-associated protein (MRP)1, a number of other molecules might mediate the drug resistance of human gastric cancer. The absence of P-gp and MRP1 expression in some gastric cancer cases also indicates that there might be other mechanisms responsible for human gastric cancer MDR. These molecules belong to different functional families and might work together to confer MDR phenotypes. The new findings may provide new clues to the mechanisms of MDR and enable the selection of new candidates for targeting MDR in human gastric cancer.

Abstract
This paper provides a bird's-eye view of our 25-year research work on gastric cancer, including both exploration of pathogenesis and preclinical or clinical applications of diagnosis and treatment. Although there have been achievements and reasons for applause, there are, nonetheless, more failings and teachings. Some problems that we experienced 25 years ago are still problems we have to face today. We are absolutely not singing the same old tune. Looking back makes us wiser and our way smoother. Although it is a long and arduous way to further study gastric cancer, we are willing to devote ourselves to it.

Abstract
Zinc ribbon domain-containing 1 (ZNRD1), a transcription-associated gene, was recently found to be downregulated in human gastric cancer tissues as compared to the matched adjacent nonneoplastic tissues. In this study, we constructed the siRNA eukaryotic expression vectors of ZNRD1 and transfected them into normal gastric epithelial cells (GES-1). We also introduced the ZNRD1 gene into gastric cancer cells that do (SGC7901) and do not (AGS) express ZNRD1 endogenously. GES-1 cells stably transfected with the ZNRD1-RNAi were found to exhibit significantly quicker proliferation than empty vector transfectants. AGS cells stably transfected with the ZNRD1 cDNA exhibited significantly decreased growth rate as compared to control vector transfectants, whereas SGC7901 cells did not. Furthermore, ZNRD1 suppresses growth of AGS cells in soft agar and tumor formation in athymic nude mice. This study clearly demonstrates that ZNRD1 may play an important role in the control of human gastric cancer development by regulating cell proliferation. These results provide new insights into the function of ZNRD1 and further validate ZNRD1 as a potential therapeutic target in gastric cancer.

Abstract
We have efficiently generated the first monoclonal antibody (MAb) against the human ZNRD1 protein, a transcription-associated protein, consisting of two zinc ribbon domains. Hybridomas were screened by indirect enzyme-linked immunosorbent assay (ELISA) using either purified 6 x His-ZNRD1fusion protein or purified 6 x His-OS-9 fusion protein as a control. One MAb named H6 (IgG(1)), effective in detecting the recombinant and cellular protein, was characterized by ELISA and Western immunoblotting. Thus, it binds to native ZNRD1 protein and should be useful in studies of ZNRD1 protein function and expression. By Western immunoblotting analysis of 16 patients with gastric cancer using the MAb, we found ZNRD1 protein was more overexpressed in incision margin than in carcinoma tissue. The results showed that ZNRD1 might be a novel modifier in gastric carcinogenesis.

Abstract
AIM To study the mechanism of tetrandrine (TTD) on proliferation and apoptosis of hepatic cell carcinoma (HCC) cell line.
METHODS MTT colorimetry was used to evaluate the influence of TTD on proliferation of cells. Flow cytometry was used to test reactive oxygen species (ROS) levels in cells. Electrophoresis in 1.5% agarose gels was used to assess the DNA laddering.
RESULTS Proliferation rate of HCC cell line stimulated by 10 and 20 μmol/L TTD at 24 h, 48 h, and 72 h was 90.1±1.0%, 77.5±2.0%, 70.2±2.9% and 56.6±1.6%, 61.6±2.0% and 47.2±1.9%, respectively (F = 40.025, P<0.001). O2- and H2O2. generated by HCC cell lines incubated with 0, 10 and 20 μmol/L TTD for 2 hours were 35 and 24.5%, 36.6 and 40.5%, 63.2 and 84.6%, respectively. Typical DNA ladder was observed after the cell line was incubated in 20 μmol/L TTD for 48 hours.
CONCLUSION TTD can induce the apoptosis of ROS of hepatic cell carcinoma cell line by generation of ROS in a dose dependent manner.
