Abstract
Until recently, bacteria have been studied in terms of their roles in infectious diseases and mainly by using isolation and culture methods. However, in practice, many bacteria existing on the earth are difficult to isolate and culture, and thus only a limited number of them have been studied to date. On the other hand, in 2005, the next-generation sequencing technology became generally available, and since then genomic analysis of bacterial flora has become widespread. As a result, it has been revealed that the lower respiratory tract, which was previously thought to be sterile, in fact has bacterial flora (a microbiome) with a high level of biodiversity. In addition, it has been found that various diseases develop and worsen depending on the balance of the bacterial flora, and in recent years, a relationship has been established between various disorders. Recent research on cancer-associated microbial communities has elucidated the reciprocal interactions among bacteria, tumors and immune cells, the bacterial pathways associated with induction of oncogenesis, and their translational significance. Nevertheless, despite the increasing evidence showing that dysbiosis is associated with lung oncogenesis, the detailed mechanisms remain to be fully elucidated. Microorganisms seem to trigger tumor initiation and progression, presumably through the production of bacterio-toxins and other pro-inflammatory factors. The purpose of this review is to present a context for the basic mechanisms and molecular functions of the airway microbiome in oncogenesis, in an effort to prevent cancer by strategies utilizing the airway microbiota, as well as summarizing the mechanisms wherein the microbiome acts as a modulator of immunotherapies in lung cancer.

Abstract
Background Inappropriate repair of DNA damage drives carcinogenesis. Lymphoid-specific helicase (HELLS) is an important component of the chromatin remodeling complex that helps repair DNA through various mechanisms such as DNA methylation, histone posttranslational modification, and nucleosome remodeling. Its role in human cancer initiation and progression has garnered recent attention. Our study aims to provide a more systematic and comprehensive understanding of the role of HELLS in the development and progression of multiple malignancies through analysis of HELLS in cancers. Methods We explored the role of HELLS in cancers using The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) database. Multiple web platforms and software were used for data analysis, including R, Cytoscape, HPA, Archs4, TISIDB, cBioPortal, STRING, GSCALite, and CancerSEA. Results High HELLS expression was found in a variety of cancers and differentially expressed across molecular and immune subtypes. HELLS was involved in many cancer pathways. Its expression positively correlated with Th2 and Tcm cells in most cancers. It also correlated with genetic markers of immunomodulators in various cancers. Conclusions Our study elucidates the role HELLS plays in promotion, inhibition, and treatment of different cancers. HELLS is a potential cancer diagnostic and prognostic biomarker with immune, targeted, or cytotoxic therapeutic value. This work is a prerequisite to clinical validation and treatment of HELLS in cancers.

Abstract
In the past few years, researchers have shed light on the immense importance of ubiquitin in numerous regulatory pathways. The post-translational addition of mono or poly-ubiquitin molecules namely "ubiquitinoylation" is therefore pivotal to maintain the cell's vitality, maturation, differentiation, and division. Part of conserving homeostasis stems from maintaining the ubiquitin pool in the vicinity of the cell's intracellular environment; this crucial role is played by deubiquitylating enzymes (DUBs) that cleave ubiquitin molecules from target molecules. To date, they are categorized into 7 families with ubiquitin carboxyl c-terminal de-hydrolase family (UCH) as the most common and well-studied. Ubiquitin C-terminal hydrolase L (UCH-L3) is a significant protein in this family as it has been implicated in many molecular and cellular processes with its mRNA identified in a range of body tissues including the brain. It goes without saying that it manifests in maintaining health and when abnormally regulated in disease. As it is an attractive small molecule drug target, scientists have used high throughput screening (HTS) and other drug discovery methods to discover inhibitors for this enzyme for the treatment of cancer and neurodegenerative diseases. In this review we present an overview of UCH-L3 catalytic mechanism, structure, its role in DNA repair and cancer along with the inhibitors discovered so far to halt its activity.

Abstract
Recently, the impact of microorganisms on tumor growth and metastasis has attracted great attention. The pathogenesis and progression of lung cancer are related to an increase in respiratory bacterial load as well as changes in the bacterial community because the microbiota affects tumors in many ways, including canceration, metastasis, angiogenesis, and treatment. The microbiota may increase tumor susceptibility by altering metabolism and immune responses, promoting inflammation, and increasing toxic effects. The microbiota can regulate tumor metastasis by altering multiple cell signaling pathways and participate in tumor angiogenesis through vascular endothelial growth factors (VEGF), endothelial cells (ECs), inflammatory factors and inflammatory cells. Tumor angiogenesis not only maintains tumor growth at the primary site but also promotes tumor metastasis and invasion. Therefore, angiogenesis is an important mediator of the interaction between microorganisms and tumors. The microbiota also plays a part in antitumor therapy. Alteration of the microbiota caused by antibiotics can regulate tumor growth and metastasis. Moreover, the microbiota also influences the efficacy and toxicity of tumor immunotherapy and chemotherapy. Finally, the effects of air pollution, a risk factor for lung cancer, on microorganisms and the possible role of respiratory microorganisms in the effects of air pollution on lung cancer are discussed.

Abstract
Ferroptosis is an iron-dependent form of programmed cell death, which plays crucial roles in tumorigenesis, ischemia–reperfusion injury and various human degenerative diseases. Ferroptosis is characterized by aberrant iron and lipid metabolisms. Mechanistically, excess of catalytic iron is capable of triggering lipid peroxidation followed by Fenton reaction to induce ferroptosis. The induction of ferroptosis can be inhibited by sufficient glutathione (GSH) synthesis via system Xc– transporter-mediated cystine uptake. Therefore, induction of ferroptosis by inhibition of cystine uptake or dampening of GSH synthesis has been considered as a novel strategy for cancer therapy, while reversal of ferroptotic effect is able to delay progression of diverse disorders, such as cardiopathy, steatohepatitis, and acute kidney injury. The ubiquitin (Ub)–proteasome pathway (UPP) dominates the majority of intracellular protein degradation by coupling Ub molecules to the lysine residues of protein substrate, which is subsequently recognized by the 26S proteasome for degradation. Ubiquitination is crucially involved in a variety of physiological and pathological processes. Modulation of ubiquitination system has been exhibited to be a potential strategy for cancer treatment. Currently, more and more emerged evidence has demonstrated that ubiquitous modification is involved in ferroptosis and dominates the vulnerability to ferroptosis in multiple types of cancer. In this review, we will summarize the current findings of ferroptosis surrounding the viewpoint of ubiquitination regulation. Furthermore, we also highlight the potential effect of ubiquitination modulation on the perspective of ferroptosis-targeted cancer therapy.

[PMID: 33688200 PMCID: PMC7935444 DOI: 10.2147/ott.s273195] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Accepted: 12/23/2020] [Indexed: 11/23/2022] Open
Abstract
Purpose Gastric adenocarcinoma is one of the most important causes of cancer death and lacks effective treatment. Eighty-four gastric adenocarcinoma tissue samples along with the clinical information were collected. After analyzing the expression of HOXC11 and LSH in the gastric adenocarcinoma tissues, we explored the prognosis of patients and its correlation with clinical characteristics. Both HOXC11 and LSH were over-expressed in MKN-45 cell lines to verify the effect of high expression of HOXC11 and LSH on GAC. Methods The expression of HOXC11 and LSH in 84 cases with gastric adenocarcinoma (GAC) was detected via immunohistochemistry, including 17 cases in stage I, 7 cases in stage II, 27 cases in stage III and 33 cases in stage IV. The expression levels of HOXC11 and LSH, and the clinicopathological characteristics of the samples, were also studied. Cell proliferation, migration, cell cycle and apoptosis assays were utilized for demonstrating malignancy of HOXC11 and LSH over-expressed cells. Results Among 84 GAC pathological samples, 12 high HOXC11 expression, and 72 showed low expression; 54.8% (46/84) high LSH expression, and 45.2% (38/84) exhibited low expression. Survival analysis of the Kaplan-Meier plotter gastric cancer datasets showed that subjects with low expression of HOXC11 and LSH had a longer survival time, with a median survival time of 40.2 and 36.4 months, while the subjects with high HOXC11 and LSH expression were only 20.5 and 10 months, respectively. Meanwhile, HOXC11 and LSH over-expressed cells showed a stronger proliferous and migratory ability, and a sped up cell cycle. Conclusion The high expression level of HOXC11 and LSH both manifested the poor survival prognosis of GAC patients, and more pronounced malignant phenotype in GAC cells indicated that HOXC11 and LSH can be a strong predictive factor of inferior disease-free survival. From this, we can consider that HOXC11 and LSH both have significant status in GAC stage and survival prediction.

Abstract
Retinoblastoma is an aggressive childhood cancer of the developing retina that initiates by biallelic RB1 gene inactivation. Tumor progression in retinoblastoma is driven by epigenetics, as retinoblastoma genomes are stable, but the mechanism(s) that drive these epigenetic changes remain unknown. Lymphoid-specific helicase (HELLS) protein is an epigenetic modifier directly regulated by the RB/E2F pathway. In this study, we used novel genetically engineered mouse models to investigate the role of HELLS during retinal development and tumorigenesis. Our results indicate that Hells-null retinal progenitor cells divide, undergo cell-fate specification, and give rise to fully laminated retinae with minor bipolar cells defects, but normal retinal function. Despite the apparent nonessential role of HELLS in retinal development, failure to transcriptionally repress Hells during retinal terminal differentiation due to retinoblastoma (RB) family loss significantly contributes to retinal tumorigenesis. Loss of HELLS drastically reduced ectopic division of differentiating cells in Rb1/p107-null retinae, significantly decreased the incidence of retinoblastoma, delayed tumor progression, and increased overall survival. Despite its role in heterochromatin formation, we found no evidence that Hells loss directly affected chromatin accessibility in the retina but functioned as transcriptional co-activator of E2F3, decreasing expression of cell cycle genes. We propose that HELLS is a critical downstream mediator of E2F-dependent ectopic proliferation in RB-null retinae. Together with the nontoxic effect of HELLS loss in the developing retina, our results suggest that HELLS and its downstream pathways could serve as potential therapeutic targets for retinoblastoma.

Abstract
Background Elucidating mechanisms in oncogenes and epigenetic modifiers are needed to gain insights into the etiology and treatment of cancer, regulation of oncogene by chromatin modifiers at post-transcriptional level is critical and remains unclear. We have investigated the role of GINS4 in NSCLC. Methods The expression of chromatin modifier lymphoid-specific helicase (LSH) and GINS4 was assessed in tumor and normal tissue from 79 patients with NSCLC with clinical characteristics. HBE, A549, H358, and H522, PC9, 95C and 95D were cultured after overexpression or silencing of GIAT4RA. Cell proliferation assay, cell migration and invasion assays, plate colony formation assay, immunofluorescence assay, Operetta® high-content screening and analysis, Western blot analysis and Co-Immunoprecipitation (Co-IP) assay, RNA immunoprecipitation assay and tumor growth assay was used to address the potential interplay of between GINS4 and LSH, and the functional of GINS4. Results GINS4 is highly expressed in lung cancer cells and tissues, and GINS4 expression is not association with clinical risk factors, but linked with clinical stage and lymphatic metastasis status. Higher expression of GINS4 poorly linked with overall survival in lung adenocarcinomas. Furthermore, GINS4 promoted many characteristics of tumorigenesis including cell growth, clonal formation, migration and invasion, epithelial–mesenchymal transition, tumor sphere and tumor growth in vivo. Interestingly, our results demonstrated that LSH increases GINS4 expression through binding to 3’UTR region of GINS4 and stabilizing its mRNA levels. Finally, LSH overexpression rescues GINS4 knockdown-induced features. Conclusions GINS4 facilitates lung cancer progression by promoting key characteristics of tumor potential, and LSH epigenetically interacts with and stabilizes GINS4 transcripts.

Lymphoid-specific helicase promotes the growth and invasion of hepatocellular carcinoma by transcriptional regulation of centromere protein F expression. Cancer Sci 2019; 110:2133-2144. [PMID: 31066149 PMCID: PMC6609811 DOI: 10.1111/cas.14037] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Revised: 04/23/2019] [Accepted: 05/01/2019] [Indexed: 02/06/2023] Open
Abstract
Lymphoid‐specific helicase (LSH) is overexpressed in tumor tissues and its overexpression is associated with poor prognosis in several cancers. However, the role and molecular mechanism of LSH in hepatocellular carcinoma (HCC) remains largely unknown. Herein, we report that LSH was overexpressed in tumor tissues of HCC, and overexpression of LSH was associated with poor prognosis from a public HCC database, and validated by clinical samples from our department. Ectopic LSH expression promoted the growth of HCC cells in vivo and in vitro. Mechanistically, LSH overexpression promoted tumor growth by activating transcription of centromere protein F (CENPF). Clinically, overexpression of LSH and/or CENPF correlated with shorter overall survival and higher cumulative recurrence rates of HCC. In conclusion, LSH promotes tumor growth of HCC through transcriptional regulation of CENPF expression. Therefore, LSH may be a novel predictor for prognosis and a potential therapeutic target for HCC.

[PMID: 30094095 PMCID: PMC6079155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Accepted: 06/06/2018] [Indexed: 06/08/2023] Open
Abstract
Recent studies suggest that individual subunits of chromatin-remodeling complexes generate epigenetically specific signaling in tumorigenicity. The impact of environmental factors on the chromatin-remodeling factor has not been thoroughly elucidated to date. We detected the expression level of SMARCA6 (SWI/SNF2-Related, Matrix-Associated, Actin-Dependent Regulator of Chromatin, Subfamily A, Member 6) in NSCLC (Non-small-cell lung carcinoma) and measured it through quantitative real-time PCR (qRT-PCR) and immunohistochemistry. The effects of BaP on proliferation and cell cycle progression were evaluated using MTT, colony formation and FACS analyses. Tumor growth in vivo was observed in a xenograft model. ChIP and qPCR were performed to validate that SMARCA6 was a potential target of AhR in NSCLC. As a result, BaP increased SMARCA6 expression. Smoking was linked with elevated SMARCA6 expression in NSCLC. BaP promoted cancer progression in vitro and in vivo. ChIP assay confirmed that BaP increases SMARCA6 expression via recruitment of AhR and induces SMARCA6 expression by facilitating AhR translocation to the nucleus. Furthermore, inhibition of AhR expression decreases SMARCA6 expression in NSCLC. Finally, knockdown of SMARCA6 attenuates BaP-induced cancer progression. This study demonstrates that BaP promotes proliferation by activation of AhR, which promotes SMARCA6 expression, and may identify new diagnostic and therapeutic targets in lung cancer.

Abstract
Baicalin hydrate (BH), a natural compound, has been investigated for many years because of its traditional medicinal properties. However, the anti-tumor activities of BH and its epigenetic role in NPC have not been elucidated. In this study, we identified that BH inhibits NPC cell growth in vivo and in vitro by inducing apoptosis and cell cycle arrest. BH epigenetically regulated genome instability by up-regulating the expression of satellite 2 (Sat2), alpha satellite (α-Sat), and major satellite (Major-Sat). BH also increased the level of IKKα, Suv39H1, and H3K9me3 and decreased LSH expression. Interestingly, BH promoted the splicing of Suv39H1 via the enhancement of m6A RNA methylation, rather than DNA methylation. Taken together, our results demonstrated that BH has an anti-tumor role in NPC and revealed a unique role of BH in genome instability and splicing in response to DNA damage.

Abstract
Metabolism is essential to all living organisms that provide cells with energy, regulators, building blocks, enzyme cofactors and signaling molecules, and is in tune with nutritional conditions and the function of cells to make the appropriate developmental decisions or maintain homeostasis. As a fundamental biological process, metabolism state affects the production of multiple metabolites and the activation of various enzymes that participate in regulating gene expression, cell apoptosis, cancer progression and immunoreactions. Previous studies generally focus on the function played by the metabolic enzymes in the cytoplasm and mitochondrion. In this review, we conclude the role of them in the nucleus and their implications for cancer progression, immunity and metastasis.

Abstract
DNA methylation is an important epigenetic modification as a hallmark in cancer. Conversion of 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC) by ten-eleven translocation (TET) family enzymes plays an important biological role in embryonic stem cells, development, aging and disease. Lymphoid specific helicase (LSH), a chromatin remodeling factor, is regarded as a reader of 5-hmC. Recent reports show that the level of 5-hmC is altered in various types of cancers. However, the change in 5-hmC levels in cancer and associated metastasis is not well defined. We report that the level of 5-hmC was decreased in metastatic tissues of nasopharyngeal carcinoma, breast cancer, and colon cancer relative to that in non-metastasis tumor tissues. Furthermore, our data show that TET2, but not TET3, interacted with LSH, whereas LSH increased TET2 expression through silencing miR-26b-5p and miR-29c-5p. Finally, LSH promoted genome stability by silencing satellite expression by affecting 5-hmC levels in pericentromeric satellite repeats, and LSH was resistant to cisplatin-induced DNA damage. Our data indicate that 5-hmC might serve as a metastasis marker for cancer and that the decreased expression of LSH is likely one of the mechanisms of genome instability underlying 5-hmC loss in cancer.
