Abstract
The senescence-associated secretory phenotype (SASP) is closely associated with the tumorigenesis and progression of intrahepatic cholangiocarcinoma (ICC). However, it remains unclear its relation to stemness of ICC. In the study, the stemness indices of ICC were calculated using one-class linear regression (OCLR) and single-sample gene set enrichment analysis (ssGSEA) algorithms. A total of 14 senescence-related stemness genes (SRSGs) were identified using Pearson correlation analysis in ICC. Subsequently, a SRSGs-related classification was established using a consensus clustering for ICC. Different types of ICC exhibit distinct prognosis, immunity, metabolisms, and oncogenic signatures. Additionally, we constructed a risk score model for ICC using principal component analysis (PCA). The risk score was positively correlated with stemness, immune infiltration, metabolisms and oncogenic signatures, but negatively with prognosis in ICC. Patients with a high risk score may respond well to immunotherapy. Furthermore, we employed 3D fibrin gels to select tumor-repopulating cells (TRC) with stemness features. We found that HELLS, belonging to the 14 SRSGs, was up-regulated in ICC-TRC. And silencing HELLS significantly reduced the colony size, inhibited migration and invasion, and attenuated SASP in ICC-TRC. In summary, we provided a novel classification and risk score for ICC and uncovered a molecular mechanism via which CSLCs could obtain an active SASP.

Abstract
Background For adrenocortical carcinoma (ACC), a rare endocrine malignancy with a high rate of mortality and recurrence, it is difficult for clinicians to predict overall survival and select the most effective treatment. Targeting ferroptosis, a form of cell death, has been reported to be a promising therapeutic strategy for ACC; however, the core ferroptosis regulator and its prognostic value in ACC remain unknown. Methods RNA sequencing data and clinical information were downloaded from public databases. Differentially expressed gene and survival analyses were performed to identify candidate ferroptosis regulators. A multivariate Cox regression model was used to construct a gene signature, and a nomogram was constructed to predict the overall survival of patients with ACC. Gene set variation analysis (GSVA) was used to identify underlying aberrant pathways and the relative immune cell infiltration levels of each ACC sample. Immunohistochemistry staining was performed in formalin-fixed paraffin-embedded tumor tissue sections. Results Ultimately, 23 differentially expressed ferroptosis regulators were identified between normal adrenal gland and ACC tissues, and 50 ferroptosis regulators were related to prognosis, with 13 ferroptosis regulators being simultaneously found to satisfy the differential expression and prognostic value. According to the multivariate Cox regression model, a ferroptosis regulator signature was constructed from 3 genes in The Cancer Genome Atlas (TCGA; hazard ratio =9.01; P=1.39×10-10), and the area under the curve (AUC) values of 3-, 5-, 8-year overall survival were 0.924, 0.906, and 0.866, respectively. The survival analysis and the receiver operating characteristic (ROC) analysis validated the prognostic value of the ferroptosis regulator signature in 3 validation datasets. Moreover, metabolism-, E2F-, MYC-, and G2/M checkpoint-related pathways and aberrant immune cell infiltration levels were identified as being responsible for the different prognosis of risk groups in ACC. HELLS was found to be a significantly differentially expressed ferroptosis-suppressor gene with a prognostic value in ACC and to be highly associated with immune cell infiltration levels and multiple biological functions. Conclusions A ferroptosis regulator signature showed promising power for predicting the prognosis of ACC, and HELLS was identified as a hub ferroptosis regulator in the initiation and progression of ACC.

Abstract
BACKGROUND Lymphoid-specific helicase (HELLS), a SNF2-like chromatin-remodeling enzyme, plays a key role in tumor progression via its DNA methylation function. However, the effects of HELLS on immune infiltration and prognosis in liver hepatocellular carcinoma (LIHC) remain uncertain. METHODS The Tumor Immune Estimation Resource (TIMER) database was employed to explore the pan-cancer mRNA expression of HELLS and its correlation with immunity. GEPIA2 was used to verify the correlation between HELLS expression and survival. The role of HELLS in cancer was explored via gene set enrichment analysis (Gene Ontology and Kyoto Encyclopedia of Genes and Genomes) and the construction of gene-gene and protein-protein interaction networks (PPI). Additionally, correlations between DNA methylation, HELLS expression, and immune-related genes were explored in LIHC. HELLS expression in LIHC clinical samples was determined using qRT-PCR and western blotting. The effects of downregulated HELLS expression in hepatocellular carcinoma cells was explored via transfection experiments in vitro. RESULTS High HELLS mRNA expression was identified in several cancers and was significantly associated with poorer prognosis in LIHC. Furthermore, HELLS expression was positively correlated with tumor-infiltrating lymphocytes and immune checkpoint genes in LIHC. Bioinformatics analysis suggested that DNA methylation of HELLS may be associated with the immune response. Results from the TCGA-LIHC dataset, clinical samples, and functional analysis indicated that HELLS contributed to tumor progression in LIHC. CONCLUSION The study findings demonstrate that HELLS is an important factor in promoting LIHC malignancy and might serve as a potential biomarker for LIHC.

Abstract
HEADING AIMS Breast cancer is one of the most common malignant tumors with a high incidence and leading cancer-related death in women worldwide. MiR-205 plays a crucial role in breast cancer initiation and progression. Here, we identified the relationship between miR-205 and lymphoid specific helicase and confirmed the significance of the miR-205/lymphoid specific helicase (miR-205/HELLS) axis. MATERIALS AND METHODS Data from The Cancer Genome Atlas (TCGA) database and Gene Expression Omnibus (GEO) database were analyzed to investigate the expression level of miR-205 and HELLS in breast cancer. The TargetScan, Starbase and miRWalk databases were used to predict the candidate target genes of miR-205. Proliferation and migration abilities were examined using cell counting kit-8 assay, colony formation assays, transwell assay and wound-healing assay. Dual-luciferase reporter assay was utilized to confirm the binding of miR-205 and HELLS. Quantitative RT-PCR, western blot assays or immunohistochemistry were conducted to detect the expression level of genes in breast cancer cells or tissues. Mice xenograft models were constructed to explore the function of miR-205 and HELLS in vivo. KEY FINDINGS Overexpressed miR-205 alleviated cancer cell proliferation and migration and influenced patients' prognosis by negatively regulating the HELLS gene. Consistently, animal experiments revealed that both overexpressing miR-205 and knocking down HELLS exhibited significant tumor growth inhibition in vivo. SIGNIFICANCE Our study demonstrated that miR-205 targets HELLS to regulate tumor progression. MiR-205 and HELLS could be considered a novel diagnosis and therapeutic molecular marker of breast cancer.

Abstract
Successful meiosis I requires that homologous chromosomes be correctly linked before they are segregated. In most organisms this physical linkage is achieved through the generation of crossovers between the homologs. Meiotic recombination co-opts and modifies the canonical homologous recombination pathway to successfully generate crossovers One of the central components of this pathway are a number of conserved DNA helicases. Helicases couple nucleic acid binding to nucleotide hydrolysis and use this activity to modify DNA or protein-DNA substrates. During meiosis I it is necessary for the cell to modulate the canonical DNA repair pathways in order to facilitate the generation of interhomolog crossovers. Many of these meiotic modulations take place in pathways involving DNA helicases, or with a meiosis specific helicase. This short review explores what is currently understood about these helicases, their interaction partners, and the role of regulatory modifications during meiosis I. We focus in particular on the molecular structure and mechanisms of these helicases.

Abstract
Cervical squamous cell carcinoma (CESC) is one of the most common cancers in women. Recent studies have proved that circular RNAs (circRNAs) could regulate the progress of CESC, but the mechanism is still indistinct. In this work, we explored the roles of circ_0072008 in CESC. The expression levels of circ_0072008, microRNA-1305 (miR-1305) and mRNA of HELLS (helicase, lymphoid specific) were detected by quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) in CESC tissues. Meanwhile, the level of HELLS was quantified by western blot analysis. Besides, the cell functions were examined by colony formation assay, 5-Ethynyl-2’-deoxyuridine (EdU) assay, wound healing assay, flow cytometry assay and western blot. Furthermore, the interaction between miR-1305 and circ_0072008 or HELLS was detected by dual-luciferase reporter assay. The function of circ_0072008 in CESC has also been further verified in vivo by xenograft model experiments. The levels of circ_0072008 and HELLS were upregulated, and the miR-1305 level was decreased in CESC tissues in contrast to that in normal tissues. For functional analysis, silencing circ_0072008 inhibited cell proliferation and cell migration, whereas enhanced cell apoptosis in CESC cells. In mechanism, circ_0072008 acted as a miR-1305 sponge to regulate the level of HELLS. Moreover, miR-1305 was confirmed to repress the progression of CESC cells by suppressing HELLS. Meanwhile, knockdown of circ_0072008 inhibited CESC cells growth in vivo. In conclusion, circ_0072008 facilitated CESC cell proliferation, migration, and invasion through increasing HELLS expression by regulating miR-1305, which also offered an underlying targeted therapy for CESC treatment.

Abstract
Several recent studies have shown that both strands of certain miRNAs derived from miRNA duplexes are involved in cancer pathogenesis. Our own recent studies revealed that both strands of the miR-150 duplex act as tumor-suppressive miRNAs in lung adenocarcinoma (LUAD) through the targeting of several oncogenes. The aim of the study here was to further investigate the tumor-suppressive roles of miR-150-3p (the passenger strand) in lung squamous cell carcinoma (LUSQ) and its control of cancer-promoting genes in LUSQ cells. The downregulation of miR-150-3p in LUSQ tissues was confirmed by data in The Cancer Genome Atlas (TCGA). The ectopic expression of miR-150-3p attenuated cancer cell aggressive features, e.g., cell cycle arrest, migration and invasive abilities. Our target search strategy successfully identified a total of 49 putative targets that were listed as subjects of miR-150-3p regulation in LUSQ cells. Interestingly, among these targets, 17 genes were categorized as related to the “cell cycle” based on Gene Ontology (GO) classification, namely CENPA, CIT, CCNE1, CCNE2, TIMELESS, BUB1, MCM4, HELLS, SKA3, CDCA2, FANCD2, NUF2, E2F2, SUV39H2, CASC5, ZWILCH and CKAP2). Moreover, we show that the expression of HELLS (helicase, lymphoid specific) is directly controlled by miR-150-3p, and its expression promotes the malignant phenotype of LUSQ cells.

Abstract
BACKGROUND SMARCAs, belonged to SWI/SNF2 subfamilies, are critical to cellular processes due to their modulation of chromatin remodeling processes. Although SMARCAs are implicated in the tumor progression of various cancer types, our understanding of how those members affect pancreatic carcinogenesis is quite limited and improving this requires bioinformatics analysis and biology approaches. METHODS To address this issue, we investigated the transcriptional and survival data of SMARCAs in patients with pancreatic cancer using ONCOMINE, GEPIA, Human Protein Atlas, and Kaplan-Meier plotter. We further verified the effect of significant biomarker on pancreatic cancer in vitro through functional experiment. RESULTS The Kaplan-Meier curve and log-rank test analyses showed a positive correlation between SMARCA1/2/3/SMARCAD1 and patients' overall survival (OS). On the other hand, mRNA expression of SMARCA6 (also known as HELLS) showed a negative correlation with OS. Meanwhile, no significant correlation was found between SMARCA4/5/SMARCAL1 and tumor stages and OS. The knockdown of HELLS impaired the colony formation ability, and inhibited pancreatic cancer cell proliferation by arresting cells at S phase. CONCLUSIONS Data mining analysis and cell function research demonstrated that HELLS played oncogenic roles in the development and progression of pancreatic cancer, and serve as a poor prognostic biomarker for pancreatic cancer. Our work laid a foundation for further clinical applications of HELLS in pancreatic cancer.

Abstract
BACKGROUND Immunodeficiency, centromeric instability and facial dysmorphism (ICF) syndrome is a rare autosomal recessive immune disorder presenting with hypogammaglobulinemia, developmental delay, and facial anomalies. The ICF type 1, type 2, type 3 and type 4 are characterized by mutations in DNMT3B, ZBTB24, CDCA7 or HELLS gene, respectively. This study aimed to present a comprehensive description of the clinical, immunologic and genetic features of patients with ICF syndrome. METHODS PubMed, Web of Science, and Scopus were searched systemically to find eligible studies. RESULTS Forty-eight studies with 118 ICF patients who met the inclusion criteria were included in our study. Among these patients, 60% reported with ICF-1, 30% with ICF-2, 4% with ICF-3, and 6% with ICF-4. The four most common symptoms reported in patients with ICF syndrome were: delay in motor development, low birth weight, chronic infections, and diarrhea. Intellectual disability and preterm birth among patients with ICF-2 and failure to thrive, sepsis and fungal infections among patients with ICF-1 were also more frequent. Moreover, the median levels of all three immunoglobulins (IgA, IgG, IgM) were markedly reduced within four types of ICF syndrome. CONCLUSION The frequency of diagnosed patients with ICF syndrome has increased. Early diagnosis of ICF is important since immunoglobulin supplementation or allogeneic stem cell transplantation can improve the disease-free survival rate.

Abstract
Gastric cancer (GC) is a common and invasive malignancy, which lacks effective treatment and is the third main reason of cancer death. Metabolic reprogramming is one of the main reasons that GC is difficult to treat in various environments. Particularly, abnormal glycolytic activity is the most common way of metabolism reprogramming in cancer cells. Numerous studies have shown that microRNAs play important roles in reprogramming glucose metabolism. Here, we found a microRNA-miR-365a-3p, was significantly downregulated in GC according to bioinformatics analysis. Low expression of miR-365a-3p correlated with poor prognosis of GC patients. Overexpression of miR-365a-3p in GC cells significantly inhibited cell proliferation by inducing cell cycle arrest at G1 phase. Notably, miR-365a-3p induced downregulation of HELLS through binding to its 3′ untranslated region (UTR). Additionally, we found that miR-365a-3p suppressed aerobic glycolysis by inhibiting HELLS/GLUT1 axis. Lastly, we shown that overexpression of miR-365a-3p significantly inhibited tumor growth in nude mice. Conversely, Reconstituted the expression of HELLS rescued the suppressive effects of miR-365a-3p. Our data collectively indicated that miR-365a-3p functioned as a tumor suppressor in GC through downregulating HELLS. Therefore, targeting of the novel miR-365a-3p/HELLS axis could be a potentially effective therapeutic approach for GC.

Abstract
Pancreatic cancer (PC) is the most malignant cancer type in the digestive system with a poor prognosis. Chemotherapy such as cisplatin is the last chance for PC patients diagnosed with advanced or metastatic disease. Obtaining a deep understanding of the molecular mechanism underlying PC tumorigenesis and identifying optimal biomarkers to estimate chemotherapy sensitivity are essential for PC treatment. The chromatin remodeler HELLS was found to regulate various tumor suppressors through an epigenetic pathway in several cancers. We analyzed HELLS expression in clinical samples by Western blotting and immunohistochemical staining. Next, we identified the variation in tumor growth and cisplatin sensitivity after knockdown of HELLS and explored the downstream mediators of HELLS in PC via RNA-seq, chromatin immunoprecipitation, and gain- and loss-of-function assays. We found that HELLS is upregulated in PC tissues and correlates with advanced clinical stage and a poor prognosis, and the knockdown of HELLS leads to tumor growth arrest and increased sensitivity to cisplatin. Mechanistically, the tumor suppressor TGFBR3 is markedly reexpressed after HELLS knockdown; conversely, compromising TGFBR3 rescues HELLS knockdown-mediated effects in PC cells. Thus, our data provide evidence that HELLS can serve as a potential oncogene and suitable biomarker to evaluate chemotherapy sensitivity via epigenetically silencing the tumor suppressor TGFBR3 in PC.

Abstract
Meiotic recombination starts with the formation of DNA double-strand breaks (DSBs) at specific genomic locations that correspond to PRDM9-binding sites. The molecular steps occurring from PRDM9 binding to DSB formation are unknown. Using proteomic approaches to find PRDM9 partners, we identified HELLS, a member of the SNF2-like family of chromatin remodelers. Upon functional analyses during mouse male meiosis, we demonstrated that HELLS is required for PRDM9 binding and DSB activity at PRDM9 sites. However, HELLS is not required for DSB activity at PRDM9-independent sites. HELLS is also essential for 5-hydroxymethylcytosine (5hmC) enrichment at PRDM9 sites. Analyses of 5hmC in mice deficient for SPO11, which catalyzes DSB formation, and in PRDM9 methyltransferase deficient mice reveal that 5hmC is triggered at DSB-prone sites upon PRDM9 binding and histone modification, but independent of DSB activity. These findings highlight the complex regulation of the chromatin and epigenetic environments at PRDM9-specified hotspots.

Abstract
The deubiquitination of histone H2A on lysine 119 by 2A-DUB/MYSM1, BAP1, USP16, and other enzymes is required for key cellular processes, including transcriptional activation, apoptosis, and cell cycle control, during normal hematopoiesis and tissue development, and in tumor cells. Based on our finding that MYSM1 colocalizes with γH2AX foci in human peripheral blood mononuclear cells, leukemia cells, and melanoma cells upon induction of DNA double-strand breaks with topoisomerase inhibitor etoposide, we applied a mass spectrometry-based proteomics approach to identify novel 2A-DUB/MYSM1 interaction partners in DNA-damage responses. Differential display of MYSM1 binding proteins significantly enriched after exposure of 293T cells to etoposide revealed an interacting network of proteins involved in DNA damage and replication, including factors associated with poor melanoma outcome. In the context of increased DNA-damage in a variety of cell types in Mysm1-deficient mice, in bone marrow cells upon aging and in UV-exposed Mysm1-deficient skin, our current mass spectrometry data provide additional evidence for an interaction between MYSM1 and key DNA replication and repair factors, and indicate a potential function of 2A-DUB/MYSM1 in DNA repair processes.

Abstract
Although lung cancer is one of the greatest threats to human health, its signaling pathway and related genes are still unknown. This study integrates data from three groups of people to study potential key candidate genes and pathways related to lung cancer. Expression profiles (GSE18842, GSE19188 and GSE27262), including 162 tumor tissue and 135 adjacent normal lung tissue samples, were integrated and analyzed. Differentially expressed genes (DEGs) and candidate genes were identified, their expression pathways were analyzed, and the diethylene glycol-related protein–protein interaction (PPI) network was analyzed. We identified 232 shared DEGs (40 upregulated and 192 down-regulated) from the three GSE datasets. The DEGs were clustered according to function and signaling pathway for significant enrichment analysis. In total, 129 nodes/DEGs were identified from the DEG PPI network complex. An improved prognosis was associated with increased Helicase, Lymphoid-Specific (HELLS) and decreased Intercellular adhesion molecule 1 (ICAM1) mRNA expression in lung cancer patients. In conclusion, we used integrated bioinformatics analysis to identify candidate genes and pathways in lung cancer to show that HELLS and ICAM1 might be the key genes related to tumorigenesis or tumor progression in lung cancer. Additional studies are needed to further explore the involved functional mechanisms.

Abstract
DNA methylation is an epigenetic modification essential for normal mammalian development. Initially associated with gene silencing, more diverse roles for DNA methylation in the regulation of gene expression patterns are increasingly being recognized. Some of these insights come from studying the function of genes that are mutated in human diseases characterized by abnormal DNA methylation landscapes. The first disorder to be associated with congenital defects in DNA methylation was Immunodeficiency, Centromeric instability, Facial anomalies syndrome (ICF). The hallmark of this syndrome is hypomethylation of pericentromeric satellite repeats, with mutations in four genes: DNMT3B, ZBTB24, CDCA7 and HELLS, being linked to the disease. Here, we discuss recent progress in understanding the molecular interactions between these genes and consider current evidence for how aberrant DNA methylation may contribute to the abnormal phenotype present in ICF syndrome patients.

Abstract
Aim Colorectal cancer (CRC) is the fourth most frequently diagnosed cancer worldwide. Despite the decrease in mortality of CRC patients, further investigation of the molecular pathogenesis of CRC could unveil new therapeutic targets and offer better prognosis predictions, which might direct attention to epigenetic regulators. Methods Publicly available data from the Gene Expression Omnibus (GEO) database and clinical samples were collected. Bioinformatics methods were used to screen hub genes expressed in CRC. qRT-PCR and Western blotting were used to experimentally determine the expression of one gene of interest, the helicase lymphoid-specific (HELLS) gene, at the RNA and protein levels. Immunohistochemical (IHC) assays were used to correlate the stained HELLS proteins to survival data. Cell proliferation levels were assayed by a CCK-8 kit, a colony formation assay was performed, and flow cytometry was used to quantify the cells at each stage of the cell cycle. Results A total of 225 overlapping genes were screened, including 14 hub genes. Analysis through a protein-protein interaction (PPI) network and the Gene Ontology database was performed by using the Cytoscape and DAVID online tools, respectively. HELLS RNA and protein expression levels in tumor tissues were 2.09-fold higher and 1.46-fold higher, respectively, than in the peritumoral tissues (p < 0.001, p<0.001). HELLS expression was significantly associated with the T stage (p=0.0027), M stage (p=0.0119), and TNM clinical stage (p = 0.0312) and a higher pathological grade (p=0.049). Highly expressed HELLS was reversibly associated with overall survival (log-rank p = 0.027). HELLS siRNA impaired cell proliferation and colony generation in vitro. HELLS siRNA induced significant G2+M arrest in HT29 and HCT116 cells compared with the respective negative controls (82.29% vs 25.85% and 35.41% vs 15.26%, respectively). Conclusion Our data revealed that HELLS was significantly upregulated in CRC and correlated with clinicopathological parameters. High expression of HELLS indicated poor prognosis for CRC patients. HELLS knockdown led to impaired cell proliferation, colony generation, and G2+M cell cycle arrest.

Wu SC, Benavente CA. Chromatin remodeling protein HELLS is upregulated by inactivation of the RB-E2F pathway and is nonessential for osteosarcoma tumorigenesis. Oncotarget 2018; 9:32580-32592.

Abstract
Osteosarcoma is the most common primary bone malignancy in children and adolescents. Among the various molecular mechanisms implicated in osteosarcomagenesis, the RB-E2F pathway is of particular importance as virtually all cases of osteosarcoma display alterations in the RB-E2F pathway. In this study, we examined the transcription factor E2F family members that are associated with increased malignancy in Rb1-null osteosarcoma tumors. Using genetically engineered mouse models of osteosarcoma, we found that loss of activator E2Fs, E2F1 and E2F3, significantly delays tumor progression and increases the overall survival of the p53/Rb1-deficient osteosarcoma mouse model. We also studied the role of helicase, lymphoid specific (HELLS), a chromatin remodeling protein identified as a critical downstream effector of the RB-E2F signaling pathway in various cancers. In this study, we confirmed that the RB-E2F pathway directly regulates HELLS gene expression. We also found that HELLS mRNA is upregulated and its protein overexpressed in osteosarcoma. Using loss-of-function assays to study the role of HELLS in human osteosarcoma, we observed that HELLS has no effect on tumor proliferation and migration. Further, we pioneered the study of Hells in developmental tumor models by generating Hells conditional knockout osteosarcoma mouse models to examine the role of HELLS in osteosarcoma tumor development. We found that loss of Hells in osteosarcoma has no effect in tumor initiation and overall survival of mice. This suggests that while HELLS may serve as a biomarker for tumorigenesis and for RB-E2F pathway status, it is unlikely to serve as a relevant target for therapeutics in osteosarcoma.

Abstract
Mutations in CDCA7, the SNF2 family protein HELLS (LSH), or the DNA methyltransferase DNMT3b cause immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome. While it has been speculated that DNA methylation defects cause this disease, little is known about the molecular function of CDCA7 and its functional relationship to HELLS and DNMT3b. Systematic analysis of how the cell cycle, H3K9 methylation, and the mitotic kinase Aurora B affect proteomic profiles of chromatin in Xenopus egg extracts revealed that HELLS and CDCA7 form a stoichiometric complex on chromatin, in a manner sensitive to Aurora B. Although HELLS alone fails to remodel nucleosomes, we demonstrate that the HELLS-CDCA7 complex possesses nucleosome remodeling activity. Furthermore, CDCA7 is essential for loading HELLS onto chromatin, and CDCA7 harboring patient ICF mutations fails to recruit the complex to chromatin. Together, our study identifies a unique bipartite nucleosome remodeling complex where the functional remodeling activity is split between two proteins and thus delineates the defective pathway in ICF syndrome.
