J Hum Genet 2023; 68:713-720. [PMID: 37365321 DOI: 10.1038/s10038-023-01167-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 05/22/2023] [Accepted: 05/23/2023] [Indexed: 06/28/2023]
Abstract
Genome-wide association study has limited to discover single-nucleotide polymorphisms (SNPs) in several ethnicities. Here, we investigated an initial GWAS to identify genetic modifiers predicting with adult moyamoya disease (MMD) in Koreans. GWAS was performed in 216 patients with MMD and 296 controls using the large-scale Asian-specific Axiom Precision Medicine Research Array. A subsequent fine-mapping analysis was conducted to assess the causal variants associated with adult MMD. A total of 489,966 out of 802,688 SNPs were subjected to quality control analysis. Twenty-one SNPs reached a genome-wide significance threshold (p = 5 × 10-8) after pruning linkage disequilibrium (r2 < 0.8) and mis-clustered SNPs. Among these variants, the 17q25.3 region including TBC1D16, CCDC40, GAA, RNF213, and ENDOV genes was broadly associated with MMD (p = 3.1 × 10-20 to 4.2 × 10-8). Mutations in RNF213 including rs8082521 (Q1133K), rs10782008 (V1195M), rs9913636 (E1272Q), rs8074015 (D1331G), and rs9674961 (S2334N) showed a genome-wide significance (1.9 × 10-8 < p < 4.3 × 10-12) and were also replicated in the East-Asian populations. In subsequent analysis, RNF213 mutations were validated in a fine-mapping outcome (log10BF > 7). Most of the loci associated with MMD including 17q25.3 regions were detected with a statistical power greater than 80%. This study identifies several novel and known variations predicting adult MMD in Koreans. These findings may good biomarkers to evaluate MMD susceptibility and its clinical outcomes.

Overexpression of Twist1 in vascular endothelial cells promotes pathological retinal angiogenesis in mice. Zool Res 2022; 43:64-74. [PMID: 34845879 PMCID: PMC8743260 DOI: 10.24272/j.issn.2095-8137.2021.281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Accepted: 11/29/2021] [Indexed: 11/07/2022] Open
Abstract
Retinal angiogenesis is a critical process for normal retinal function. However, uncontrolled angiogenesis can lead to pathological neovascularization (NV), which is closely related to most irreversible blindness-causing retinal diseases. Understanding the molecular basis behind pathological NV is important for the treatment of related diseases. Twist-related protein 1 (TWIST1) is a well-known transcription factor and principal inducer of epithelial-mesenchymal transition (EMT) in many human cancers. Our previous study showed that Twist1 expression is elevated in pathological retinal NV. To date, however, the role of TWIST1 in retinal pathological angiogenesis remains to be elucidated. To study the role of TWIST1 in pathological retinal NV and identify specific molecular targets for antagonizing pathological NV, we generated an inducible vascular endothelial cell (EC)-specific Twist1 transgenic mouse model ( Tg-Twist1 iEC+ ). Whole-mount retinas from Tg-Twist1 iEC+ mice showed retarded vascular progression and increased vascular density in the front end of the growing retinal vasculature, as well as aneurysm-like pathological retinal NV. Furthermore, overexpression of Twist1 in the ECs promoted cell proliferation but disturbed cell polarity, thus leading to uncontrolled retinal angiogenesis. TWIST1 promoted pathological NV by activating the Wnt/β-catenin signaling pathway and inducing the expression of NV formation-related genes, thereby acting as a 'valve' in the regulation of pathological angiogenesis. This study identified the critical role of TWIST1 in retinal pathological NV, thus providing a potential therapeutic target for pathological NV.

WLS/wntless is essential in controlling dendritic cell homeostasis via a WNT signaling-independent mechanism. Autophagy 2021; 17:4202-4217. [PMID: 33853474 PMCID: PMC8726611 DOI: 10.1080/15548627.2021.1907516] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 03/15/2021] [Accepted: 03/18/2021] [Indexed: 01/19/2023] Open
Abstract
We propose that beyond its role in WNT secretion, WLS/GPR177 (wntless, WNT ligand secretion mediator) acts as an essential regulator controlling protein glycosylation, endoplasmic reticulum (ER) homeostasis, and dendritic cell (DC)-mediated immunity. WLS deficiency in bone marrow-derived DCs (BMDCs) resulted in poor growth and an inability to mount cytokine and T-cell responses in vitro, phenotypes that were irreversible by the addition of exogenous WNTs. In fact, WLS was discovered to integrate a protein complex in N-glycan-dependent and WLS domain-selective manners, comprising ER stress sensors and lectin chaperones. WLS deficiency in BMDCs led to increased ER stress response and macroautophagy/autophagy, decreased calcium efflux from the ER, and the loss of CALR (calreticulin)-CANX (calnexin) cycle, and hence protein hypo-glycosylation. Consequently, DC-specific wls-null mice were unable to develop both Th1-, Th2- and Th17-associated responses in the respective autoimmune and allergic disease models. These results suggest that WLS is a critical chaperone in maintaining ER homeostasis, glycoprotein quality control and calcium dynamics in DCs.Abbreviations: ATF6: activating transcription factor 6; ATG5: autophagy related 5; ATG12: autophagy related 12; ATG16L1: autophagy related 16 like 1; ATP2A1/SERCA1: ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 1; BALF: bronchoalveolar lavage fluid; BFA: brefeldin A; BMDC: bone marrow-derived dendritic cell; CALR: calreticulin; CANX: calnexin; CCL2/MCP-1: C-C motif chemokine ligand 2; CNS: central nervous system; CT: C-terminal domain; DTT: dithiothreitol; DNAJB9/ERDJ4: DnaJ heat shock protein family (Hsp40) member B9; EAE: experimental autoimmune encephalomyelitis; EIF2A/eIF2α: eukaryotic translation initiation factor 2A; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; ERN1/IRE1: endoplasmic reticulum (ER) to nucleus signaling 1; GFP: green fluorescent protein; HSPA5/GRP78/BiP: heat shock protein A5; IFNA: interferon alpha; IFNAR1: interferon alpha and beta receptor subunit 1; IFNB: interferon beta; IFNG/INFγ: interferon gamma; IFNGR2: interferon gamma receptor 2; IL6: interleukin 6; IL10: interleukin 10; IL12A: interleukin 12A; IL23A: interleukin 23 subunit alpha; ITGAX/CD11c: integrin subunit alpha X; ITPR1/InsP3R1: inositol 1,4,5-trisphosphate receptor type 1; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; OVA: ovalbumin; PIK3C3/VPS34: phosphatidylinositol 3-kinase catalytic subunit type 3; PLF: predicted lipocalin fold; PPP1R15A/GADD34: protein phosphatase 1 regulatory subunit 15A; RYR1/RyanR1: ryanodine receptor 1, skeletal muscle; SD: signal domain; TGFB/TGF-β: transforming growth factor beta family; Th1: T helper cell type 1; Th17: T helper cell type 17; TM: tunicamycin; TNF/TNF-α: tumor necrosis factor; UPR: unfolded protein response; WLS/wntless: WNT ligand secretion mediator.

C-Myc-activated long non-coding RNA LINC01050 promotes gastric cancer growth and metastasis by sponging miR-7161-3p to regulate SPZ1 expression. J Exp Clin Cancer Res 2021; 40:351. [PMID: 34749766 PMCID: PMC8573944 DOI: 10.1186/s13046-021-02155-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 10/25/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Growing evidence shows that long non-coding RNAs (lncRNAs) play significant roles in cancer development. However, the functions of most lncRNAs in human gastric cancer are still not fully understood. Here, we explored the role of a novel c-Myc-activated lncRNA, LINC01050, in gastric cancer progression. METHODS The expression of LINC01050 in the context of gastric cancer was assessed using The Cancer Genome Atlas datasets. Its functions in gastric cancer were investigated through gain- and loss-of-function experiments combined with the Cell Counting Kit-8 assays, colony-forming assays, Transwell assays, flow cytometry, Western blot analyses, and xenograft tumor and mouse metastasis models. Potential LINC01050 transcription activators were screened via bioinformatics and validated by chromatin immunoprecipitation and luciferase assays. The interaction between LINC01050 and miR-7161-3p and the targets of miR-7161-3p were predicted by bioinformatics analysis and confirmed by a luciferase assay, RNA immunoprecipitation, RNA pull-down, and rescue experiments. RESULTS LINC01050 was significantly up-regulated in gastric cancer, and its high expression was positively correlated with a poor prognosis. The transcription factor c-Myc was found to directly bind to the LINC01050 promoter region and activate its transcription. Furthermore, overexpression of LINC01050 was confirmed to promote gastric cancer cell proliferation, migration, invasion, and epithelial-mesenchymal transition in vitro and tumor growth in vivo. At the same time, its knockdown inhibited gastric cancer cell proliferation, migration, invasion, and epithelial-mesenchymal transition in vitro along with tumor growth and metastasis in vivo. Moreover, mechanistic investigations revealed that LINC01050 functions as a molecular sponge to absorb cytosolic miR-7161-3p, which reduces the miR-7161-3p-mediated translational repression of SPZ1, thus contributing to gastric cancer progression. CONCLUSIONS Taken together, our results identified a novel gastric cancer-associated lncRNA, LINC01050, which is activated by c-Myc. LINC01050 may be considered a potential therapeutic target for gastric cancer.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2021; 28:43684-43697.

Abstract
Silica nanoparticles (SiNPs), which are the main inorganic components of atmospheric particulate matter, have been proved to have certain male reproductive toxicity in previous studies. Spermatogenesis involves complex epigenetic regulation, but it is still unclear if SiNPs exposure will interfere with the DNA methylation patterns in mouse spermatocytes. The present study was designed to investigate the effects of SiNPs on DNA methylation in the mouse spermatocyte GC-2spd(ts). GC-2 cells were treated with 0 and 20 μg/mL SiNPs for 24 h. MeDIP-seq assay was then performed to analyze the differentially methylated genes related to spermatogenesis. The results showed that SiNPs induced extensive methylation changes in the genome of GC-2 cells, and 24a total of 428 hyper-methylated genes and 398 hypo-methylated genes were identified. Gene Ontology and pathway analysis showed that differential DNA methylation induced by SiNPs was probably involved with abnormal transcription and translation, mitochondrial damage, and cell apoptosis. Results from qRT-PCR verification showed that the expression of spermatogenesis-related genes Akap1, Crem, Spz1, and Tex11 were dysregulated by SiNPs exposure, which was consistent with the MeDIP-seq assay. In general, this study suggested that SiNPs caused genome-wide DNA methylation changes in GC-2 cells, providing valuable reference for the future epigenetic studies in SiNPs-induced male reproductive toxicity.

SPZ1 promotes deregulation of Bim to boost apoptosis resistance in colorectal cancer. Biosci Rep 2021; 134:155-167.

Abstract
Colorectal cancer (CRC) is the third most common malignancies in adults. Similar to other solid tumors, CRC cells show increased proliferation and suppressed apoptosis during the development and progression of the disease. Previous studies have shown that a novel tumor oncogene, spermatogenic basic helix-loop-helix transcription factor zip 1 (SPZ1), can promote proliferation. However, it is unclear whether SPZ1 plays a role in suppressing apoptosis, and the molecular mechanism behind SPZ1's suppression of apoptosis in CRC remains unclear. Here, we found that silencing endogenous SPZ1 inhibits cell growth and induces apoptosis, and overexpression of SPZ1 promotes cell growth. These findings were corroborated by in vitro and in vivo studies. Interestingly, SPZ1 overexpressing cells were resistant to 5-fluorouracil, a drug commonly used to treat cancer. Moreover, knocking down SPZ1 led to the activation of caspase through the deregulation of Bim by ERK1/2, we found that CRC tissues had significantly higher SPZ1 and lower Bim expression, and SPZ1HBimL were associated with advanced clinical stage of CRC. Collectively, our findings demonstrate that SPZ1 contributes to tumor progression by limiting apoptosis. SPZ1 reduces apoptosis by altering the stability of Bim, suggesting SPZ1 may serve as a biomarker and therapeutic target for CRC.

Abstract
Colorectal cancer (CRC) is a biologically heterogeneous disease. To characterize its mutational profile, we conduct targeted sequencing of 205 genes for 2,105 CRC cases with survival data. Our data shows several findings in addition to enhancing the existing knowledge of CRC. We identify PRKCI, SPZ1, MUTYH, MAP2K4, FETUB, and TGFBR2 as additional genes significantly mutated in CRC. We find that among hypermutated tumors, an increased mutation burden is associated with improved CRC-specific survival (HR = 0.42, 95% CI: 0.21–0.82). Mutations in TP53 are associated with poorer CRC-specific survival, which is most pronounced in cases carrying TP53 mutations with predicted 0% transcriptional activity (HR = 1.53, 95% CI: 1.21–1.94). Furthermore, we observe differences in mutational frequency of several genes and pathways by tumor location, stage, and sex. Overall, this large study provides deep insights into somatic mutations in CRC, and their potential relationships with survival and tumor features. Large scale sequencing study is of paramount importance to unravel the heterogeneity of colorectal cancer. Here, the authors sequenced 205 cancer genes in more than 2000 tumours and identified additional mutated driver genes, determined that mutational burden and specific mutations in TP53 are associated with survival odds.

Abstract
Linker histone H1 is mainly localized in the linker DNA region, between two nucleosome cores, and regulates chromatin structures linking gene expression. There are 11 variants in histone H1, and each variant has unique functions. Our previous study demonstrates that one of the H1 variants, H1T is mainly localized in the nucleolus and targets the rDNA repeat region. Moreover, H1T condenses the chromatin structures on rDNA to repress pre-rRNA expression. Although H1T is partially localized in the nucleoplasm area, the functions of H1T in the non-repeat genic region are unclear. In this study, we aimed to identify the target loci and the role of H1T in the genic region. Chromatin immunoprecipitation sequencing analysis showed that H1T is localized around the transcriptional start site and the chromatin structures of the region were relaxed. H1T knockdown and overexpression experiments revealed that H1T induced chromatin de-condensation and was associated with the increased expression of target genes. Moreover, we observed H1T co-localization with transcriptional factor SPZ1 on the genic region. Collectively, H1T has opposing roles in the genic region and in rDNA repeats; H1T functions to facilitate chromatin relaxation linked gene activation.

Abstract
OBJECTIVE To identify the genetic cause of a pedigree with four patients with 46,XY pure gonadal dysgenesis (PGD). DESIGN Genetic mutation study. SETTING Academic medical center. PATIENT(S) Four first cousins, from three households of a Chinese pedigree, affected by 46,XY PGD. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The patients were studied from clinical and genetic perspectives. Whole-genome sequencing was conducted in family members. RESULT(S) Four first cousins in the third generation were affected by 46,XY PGD. A specific familial characteristic was the prevalence of as high as 100% of gonadal tumors in patients. Whole-genome sequencing identified a new ferritin heavy chain-like 17 (FTHL17) mutation, c.GA442_443TT (p.E148L), which has the potential to interfere with protein function and cause 46,XY PGD. Moreover, the location (Xp21.2) of the FTHL17 gene proves that the family is X-linked recessive. In vitro functional study revealed that the perturbation of FTHL17 caused the decrease of protein expression and cell proliferation. CONCLUSION(S) We describe the first 46,XY PGD pedigree that may be attributed to mutations of the FTHL17 gene. We speculated that the FTHL17 gene is involved in the testis-determining pathway and tumorigenesis.

Abstract
Metastasis is the main cause of cancer mortality. However, the triggering mechanisms and regulation of epithelial-mesenchymal transition (EMT) factors in the commitment of metastasis have not been well characterized. Spermatogenic Zip 1 (SPZ1) acts as a proto-oncogene and an upstream regulator of EMT during tumorigenesis. Here we report that the HIV-1 Tat-interacting protein 60 kDa (Tip60) acetyltransferase mediates acetylation at lysine residues of SPZ1 at positions 369 and 374, and of TWIST1 at positions 73 and 76, which are required for SPZ1-TWIST1 complex formation and cancer cell migration in vitro and in vivo. Ectopic SPZ1 and TWIST1 expression, but not that of TWIST1 alone, enhanced vascular endothelial growth factor (VEGF) expression via the recruitment of bromodomain-containing protein 4 (BRD4), thus enhancing RNA-Pol II-dependent transcription and inducing metastasis. Neutralization of VEGF using humanized monoclonal antibodies such as Avastin, effectively abrogated the EMT and oncogenesis induced by the acetylated SPZ1-TWIST1 complex. Our findings highlight the importance of acetylation signaling in the SPZ1-TWIST1-BRD4 axis in the mediation of EMT and its regulation during tumor initiation and metastasis.

Abstract
It is believed that chemotherapeutic agents can enhance the malignancy of treated cancer cells in clinical situations, which is a major problem for chemotherapy. However, the underlying molecular mechanisms are still not fully understood. Here, we demonstrated that chemotherapy up-regulates the levels of spermatogenic bHLH transcription factor zip 1 (SPZ1), and knockdown of SPZ1 in drug resistant breast cancers showed that SPZ1 is critical for regulating the chemoresistance, migration, invasion and epithelial-mesenchymal transition (EMT) in a Twist1-dependent manner. Moreover, suppressing SPZ1-Twist1 axis decreased the growth of tumor xenografts. Notably, we found a positive correlation between SPZ1 and Twist1 in breast cancer samples from patients with anthracycline or taxane-based chemotherapy. Thus, our results revealed a novel role of SPZ1 as an inducer of chemoresistance and aggressiveness under chemotherapy, and this suggests that therapeutic targeting of SPZ1 may not only enhance the sensitivity of breast cancer to chemotherapy, but also suppress breast cancer invasion and metastases.

Abstract
OBJECTIVE To investigate the role of Twist in regulating the proliferation, migration, and invasion of osteosarcoma cells with different levels of malignancy. METHODS The baseline expressions of Twist in 3 different osteosarcoma cell lines (143B, MG63 and TE85) were detected using real-time PCR and Western blotting. The cells were infected with the recombinant adenoviruses Ad-Twist or Ad-siTwist for Twist overexpression or knockdown, respectively, and the cell growth curves were drawn to assess the cell proliferation. The migration abilities and invasiveness of the cells were evaluated using wound healing assay and Transwell assay. Luc-labeled 143B cells infected with Ad-Twist or Ad-siTwist were intrathecally injected to establish nude mouse models bearing osteosarcoma xenografts, in which the tumor formation was monitored using living body imaging technique. RESULTS The baseline expressions of Twist in the 3 osteosarcoma cells were significantly higher than that in C3H10 cells (P<0.05). Twist expression was the highest in 143B cells followed by MG63 cells, and was the lowest in TE85 cells, indicating its positive correlation with the level of malignancy of the osteosarcoma cells. Ad-Twist or Ad-siTwist infection efficiently enhanced or lowered Twist expressions at both mRNA and protein levels in osteosarcoma cells (P<0.05). Twist overexpression resulted in enhanced proliferation, migration and invasion abilities of osteosarcoma cells, and Twist knockdown obviously inhibited the cell proliferation, migration and invasion. In nude mice, 143B cells with Twist overexpression showed accelerated tumor formation compared with the control cells, while Twist knockdown significantly inhibited the tumor formation ability of the cells. CONCLUSION Twist overexpression can promote the proliferation, migration, invasion and tumorigenicity of osteosarcoma cells.

Abstract
Rap1b was found be dysregulated in several types of cancers. Previously, we have demonstrated that Rap1b affects proliferation, migration and invasion of hepatocellular carcinoma (HCC) cells. However, the definite function of Rap1b in HCC remains unknown. Here, we reported that Rap1b was significantly up-regulated in HCC tissues compared with the non-tumoral liver tissues. Overexpression of Rap1b promoted tumor growth and migration in vitro and tumor formation in vivo. Oppositely, inhibition of Rap1b suppressed the proliferation and migration of HCC cells. Mechanism study revealed that Rap1b could up-regulate Twist 1 expression by enhancing its promoter activity. We concluded that Rap1b increased Twist 1 expression by targeting its promoter activity to induce proliferation and migration of HCC cells.

Abstract
BACKGROUND To detect the expression of lncRNA HOXA11-AS and its biological effect in breast cancer. MATERIAL AND METHODS In this study, fluorescent quantitative real-time PCR (qRT-PCR), MTT assay and clone formation assay, flow cytometry, Transwell assay and wound healing assay, immunofluorescence, and Western blot analysis were conducted to detect the expression of lncRNA HOXA11-AS, cell proliferation activity, cell apoptosis rate and cell cycle distribution, the changes of cell invasion and metastasis capacity, and the expressions of molecular markers of epithelial-mesenchymal transition (EMT), respectively. Additionally, a nude mouse metastatic tumor model was established to study the influence of lncRNA HOXA11-AS on invasion and metastasis capacity of breast cancer cells. RESULTS The qRT-PCR experiment results showed that HOXA11-AS expression in breast cancer tissue of 50 patients was relatively higher than that in tissue adjacent to cancer. MTT assay suggested that tumor cell proliferation capacity was suppressed followed by the knockdown of lncRNA HOXA11-AS expression in MDA-MB-231 and MCF-7 cells; flow cytometry results demonstrated that interfering in lncRNA HOXA11-AS could induce tumor cell apoptosis and promote cell cycle progression to be arrested in G1/G0 stage; experiments in vivo/vitro manifested that interfering in lncRNA HOXA11-AS could inhibit tumor cell invasion and migration capacity by affecting the expressions of EMT-related molecular markers (E-cadherin, N-cadherin, Vimentin). CONCLUSIONS High expression of lncRNA HOXA11-AS promotes breast cancer invasion and metastasis by affecting EMT, and interfering in lncRAN HOXA11-AS expression provides a theoretical basis and important molecular target for inhibiting the distant metastasis of breast cancer in clinical practice.
