Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is a hematologic heterogeneous disease. This study explored the mechanism of specificity protein 1/3 (Sp1/3) in T-ALL cells through β-catenin by acting as targets of miR-495-3p. Expression levels of miR-495-3p, Sp1, Sp3, and β-catenin in the serum from T-ALL children patients, healthy controls, and the T-ALL cell lines were measured. The cell proliferation ability and apoptosis rate were detected. Levels of proliferation-related proteins proliferating cell nuclear antigen (PCNA)/cyclinD1 and apoptosis-related proteins B-cell lymphoma-2 associated X protein (Bax)/B-cell lymphoma-2 (Bcl-2) were determined. The binding of Sp1/3 and β-catenin promoter and the targeted relationship between miR-495-3p with Sp1/3 were analyzed. Sp1/3 were upregulated in CD4+ T-cells in T-ALL and were linked with leukocyte count and risk classification. Sp1/3 interference prevented proliferation and promoted apoptosis in T-ALL cells. Sp1/3 transcription factors activated β-catenin expression. Sp1/3 enhanced T-ALL cell proliferation by facilitating β-catenin expression. miR-495-3p targeted and repressed Sp1/3 expressions. miR-495-3p overexpression inhibited T-ALL cell proliferation and promoted apoptosis. Conjointly, Sp1/3, as targets of miR-495-3p limit apoptosis and promote proliferation in T-ALL cells by promoting β-catenin expression.

Transcriptome RNA Sequencing Reveals That Circular RNAs Are Abundantly Expressed in Embryonic Breast Muscle of Duck. Vet Sci 2023; 10:vetsci10020075. [PMID: 36851380 PMCID: PMC10004440 DOI: 10.3390/vetsci10020075] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/14/2023] [Accepted: 01/17/2023] [Indexed: 01/20/2023] Open
Abstract
Circular RNAs are widespread in various species and have important roles in myogenesis. However, the circular RNAs involved in breast muscle development in ducks have not yet been studied. Here, to identify circular RNAs during duck skeletal muscle development, three pectorales from Shan Ma ducks at E13 and E19, which represent undifferentiated and differentiated myoblasts, respectively, were collected and subjected to RNA sequencing. A total of 16,622 circular RNAs were identified, of which approximately 80% were exonic circular RNAs and 260 were markedly differentially expressed between E19 and E13. The parental genes of the differentially expressed circular RNAs were significantly enriched in muscle-related biological processes. Moreover, we found that the overexpression of circGAS2-2 promoted cell cycle progression and increased the proliferation viability of duck primary myoblasts; conversely, knockdown of circGAS2-2 retarded the cell cycle and reduced the proliferation viability of myoblasts. Taken together, our results demonstrate that circular RNAs are widespread and variously expressed during the development of duck skeletal muscle and that circGAS2-2 is involved in the regulation of myogenesis.

PHARMACEUTICAL BIOLOGY 2022; 60:417-426. [PMID: 35175172 PMCID: PMC8856102 DOI: 10.1080/13880209.2022.2032206] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 12/29/2021] [Accepted: 01/16/2022] [Indexed: 06/14/2023]
Abstract
CONTEXT Osthole shows antitumor effects in various tumours. Studies describing the effect of osthole on retinoblastoma (RB) are rare. OBJECTIVE This study investigates the antitumor activity of osthole on RB. MATERIALS AND METHODS RB cells were treated with different concentrations of osthole and then subjected to cell viability, colony formation, apoptosis, and western blot assays. The expression of hsa_circ_0007534 in RB tissues was determined by qRT-PCR. Hsa_circ_0007534 overexpression plasmid (oe-circ_0007534), miR-214-3p mimics and negative controls were transfected into RB cells to investigate cell viability. Athymic nude mice were injected with Y-79 cells to establish subcutaneous RB models. These mice were treated with osthole (0.5 mmol/kg) or corn oil for 36 days. Tumour tissues were collected for further analysis. RESULTS Osthole inhibited cell viability of RB cells with an IC50 of 200 μM for 24 h treatment and 120 μM for 48 h treatment, respectively. Hsa_circ_0007534 was increased significantly in RB tissues as compared to the matched nontumor tissues (p < 0.001). Oe-circ_0007534 counteracted the inhibitory effect of osthole on cell viability and colony numbers of Y-79 cells (p < 0.01). In vivo experiments indicated osthole significantly decreased the expression of hsa_circ_0007534 (p < 0.01) and increased the level of miR-214-3p in vivo. Furthermore, as compared to the control, osthole decreased the ratios of p-PI3K/PI3K, p-AKT/AKT and p-mTOR/mTOR (p < 0.01). However, hsa_circ_0007534 overexpression reversed the effect of osthole on the PI3K/AKT/mTOR pathway. DISCUSSION AND CONCLUSIONS Osthole exhibited an antitumour effect in RB, providing a scientific basis for further research and clinical applications of osthole in RB treatment.

Abstract
Although growth arrest‐specific protein 2 (GAS2) promotes the growth of T‐cell acute lymphoblastic leukemia (T‐ALL) cells in culture, the effect of GAS2 on T‐cell leukemogenesis has not been studied, and the mechanism remains unclear. In the present study, xenograft studies showed that GAS2 silencing impaired T‐cell leukemogenesis and decreased leukemic cell infiltration. Mechanistically, GAS2 regulated the protein expression of C‐X‐C chemokine receptor type 4 (CXCR4) rather than its transcript expression. Immunoprecipitation revealed that GAS2 interacted with CXCR4, and confocal analysis showed that GAS2 was partially co‐expressed with CXCR4, which provided a strong molecular basis for GAS2 to regulate CXCR4 expression. Importantly, CXCR4 overexpression alleviated the inhibitory effect of GAS2 silencing on the growth and migration of T‐ALL cells. Moreover, GAS2 or CXCR4 silencing inhibited the expression of NOTCH1 and c‐MYC. Forced expression of c‐MYC rescued the growth suppression induced by GAS2 or CXCR4 silencing. Meanwhile, GAS2 deficiency, specifically in blood cells, had a mild effect on normal hematopoiesis, including T‐cell development, and GAS2 silencing did not affect the growth of normal human CD3+ or CD34+ cells. Overall, our data indicate that GAS2 promotes T‐cell leukemogenesis through its interaction with CXCR4 to activate NOTCH1/c‐MYC, whereas impaired GAS2 expression has a mild effect on normal hematopoiesis. Therefore, our study suggests that targeting the GAS2/CXCR4 axis is a potential therapeutic strategy for T‐ALL.

Abstract
Background: The use of molecular methods in cancer diagnosis has led to a better prognosis. One of the important gene families in the carcinogenic pathways of various cancers is the forkhead box (FOX) family genes. Moreover, developmental transcription factors and proapoptotic proteins play critical roles in cell function and carcinogenesis. Objectives: The current study aimed to evaluate the expression of A1 FOXA1, FOXA2, SOX10, and growth arrest specific 2 (GAS2) genes in oral squamous cell carcinoma (OSCC) tumors due to biomarker discovery and early diagnosis of cancer. Methods: To evaluate the expression of FOXA1, FOXA2, SOX10, and GAS2 genes, 30 OSCC samples and 30 normal specimens were obtained from Imam Khomeini Hospital Cancer Institute. RNA extraction and cDNA synthesis were done by relevant kits. After a specific primer design for FOXA1, FOXA2, SOX10, and GAS2 genes, real-time PCR was done to evaluate the genes’ expression for molecular biomarker discovery and validation. ANOVA and independent t-test were used to analyze the data. Results: Significant differences were observed in the expression of the studied genes in tumor and control tissues (P < 0.001). The results showed that FOXA1, GAS2, and SOX10 expressions in tumor and normal cells have significant differences (P < 0.001). Regardless of FOXA1, FOXA2 and SOX10, there was a significant difference in the expression of GAS2 genes in term patients’ age (P < 0.05) and overexpressed in patients over 55 years. SOX10 gene is upregulated in grade II OSCC tumors but there is no significant difference in expression of FOXA1, FOXA2, and GAS2 in different stages and grades. The ROC curve analysis, FOXA1, and FOXA2 showed AUC = 0.66 and AUC = 0.57 respectively. Meanwhile, SOX10 and GAS2 showed AUC = 0.9 and AUC = 1 respectively. Conclusions: In general, the expression of FOXA1, GAS2, and SOX10 genes in cancer and control tissues were different, and therefore the role of these genes in OSCC is confirmed. Also, in the present study, the biomarker potential of SOX10 and GAS2 genes for OSCC diagnosis was demonstrated. In the current study, the important role of the studied genes in OSCC diagnosis was shown. However, further studies are needed to confirm this.

Abstract
INTRODUCTION Acute lymphoblastic leukemia (ALL) is a usual hematological tumor, which was featured by malignant proliferation of lymphoid progenitor cells. Many important factors participate into the regulation of ALL, including proteins. PAQR3 (also named RKTG) has been proved to take part in many human cancers by acting as a tumor suppressor. PAQR3 has bee n shown to repress human leukemia cells proliferation and induce cell apoptosis, but its role and relevant regulatory mechanism on cell proliferation and ferroptosis in ALL needs more exploration. METHODS The genes expression was detected through quantitative reverse transcription polymerase chain reaction (mRNA) or western blot (protein). The cell proliferation was assessed through Cell Counting Kit-8 and 5-ethynyl-2-deoxyuridine assays. The levels of MDA, DCF, and intracellular free Fe in ALL cells were tested through the commercial kits. The cell apoptosis was determined through flow cytometry analysis. The binding ability of PAQR3 and nuclear factor erythroid 2-related factor 2 (Nrf2) was verified through pull down assay. RESULTS PAQR3 expression was firstly assessed in ALL patients and cell lines, and discovered to be downregulated. It was verified that PAQR3 suppressed ALL cells proliferation. Further experiments proved that PAQR3 aggravates ferroptosis in ALL. In addition, AQR3 bound with Nrf2, and modulated its expression through ubiquitination in ALL. Finally, through rescue assays, it was demonstrated that Nrf2 overexpression reversed the effects of PAQR3 on cell proliferation and ferroptosis. CONCLUSION Findings from our work uncovered that PAQR3 inhibited proliferation and aggravated ferroptosis in ALL through modulation Nrf2 stability. This study suggested that PAQR3 may serve as an effective biological marker for ALL treatment.

Abstract
BACKGROUND Genetic and epigenetic dysregulation of Wnt signaling pathway is widely linked up with abnormal proliferation and/or epithelial-to-mesenchymal transition, in different cancer cell types. OBJECTIVE In the present research, we have tested whether promoter DNA methylation of a set of Wnt/non-Wnt genes such as [cadherin-2 (CDH2)], "present in circulation", could serve as "bone-marrow biopsy surrogate" and help in diagnosing the status, sub-type or treatment outcome in pediatric acute lymphoblastic leukemia (ALL) patients. METHODS Promoter DNA methylation was quantified in the bisulfite modified blood from the pediatric ALL patients (n= 86) in comparison with age-matched cancer-free subjects (n= 28), using real-time methylation specific PCR followed by rigorous statistical validations. RESULTS The observed methylation index, sensitivity and specificity of selected molecular markers (viz., SALL1, WNT5α, LRP1b, CDH2) in patients' liquid-biopsies was clinically significant showing high positive correlation in the pre-B ALL cases (p-value < 0.001). A substantial drop in promoter methylation signal of the follow-up/post-treatment patients was also noted (p-value < 0.001), which suggested an impending role of minimally invasive liquid-biopsy approach in the diagnosis and/or therapeutic monitoring of pediatric leukemia. CONCLUSIONS Whilst the reported metadata provides useful insight into the plausible involvement of epigenetic glitches in leukemogensis, our findings strengthen the remarkable functional consequences of dysregulated Wnt signaling genes in the hematological malignancies besides offering a novel panel of epigenetic marks.

Abstract
Background MicroRNAs (miRNAs) have been shown to be associated with osteoarthritis (OA) progression. This study aimed to explore the role of miR-520c-3p in OA progression. Methods Expression levels of miR-520c-3p and Growth arrest-specific 2 (GAS2) were detected using quantitative real-time PCR. The proliferation and apoptosis of cells were measured using cell counting kit 8 (CCK8) assay and flow cytometry. Furthermore, the protein levels of apoptosis-related markers, extracellular degradation markers, inflammatory response markers, and GAS2 were tested using quantitative real-time polymerase chain reaction (RT-PCR) and western blot (WB) analysis. In addition, the interaction between miR-520c-3p and GAS2 was examined using dual luciferase reporter assay. Results GAS2 was highly expressed, and miR-520c-3p was lowly expressed in OA cartilage tissues. miR-520c-3p could promote the proliferation and inhibit the apoptosis and inflammation of OA chondrocytes. miR-520c-3p could be sponged by GAS2, and its inhibitor could reverse the regulation of GAS2 on the biological functions of OA chondrocytes. GAS2 was a target of miR-520c-3p, which was identified by bioinformatic analysis and dual-luciferase reporter assay. Overexpression of GAS2 could inhibit the proliferation and promoted the apoptosis and inflammation of OA chondrocytes. Conclusion Our data showed that miR-520c-3p might regulate the GAS2 to inhibit the progression of OA.

Abstract
Background Growth arrest–specific 2 like 3 (GAS2L3) is a cytoskeleton-associated protein that interacts with actin filaments and tubulin. Abnormal GAS2L3 expression has been reported to be associated with carcinogenesis. However, the biological role of GAS2L3 in glioma remains to be determined. Methods The transcriptome level of GAS2L3 and its relationship with clinicopathological characteristics were analyzed among multiple public databases and clinical specimens. Bioinformatics analyses were conducted to explore biological functions and prognostic value of GAS2L3 in glioma. Results GAS2L3 was substantially expressed in glioma, and high GAS2L3 expression correlated with shorter overall survival time and poor clinical variables. Gene set enrichment analysis (GSEA), single-sample gene-set enrichment analysis, and CIBERSORT algorithm analyses showed that GAS2L3 expression was closely linked to immune-related pathways, inflammatory activities, and immune cell infiltration. Moreover, GAS2L3 was synergistic with T cell–inflamed gene signature, immune checkpoints, T-cell receptor diversities, and neoantigen numbers. Conclusion This study suggests that GAS2L3 is a prognostic biomarker for glioma, providing a reference for further study of the potential role of GAS2L3 in the immunomodulation of glioma.

Abstract
Members of the growth arrest–specific 2 (GAS2) protein family consist of a putative actin‐binding (CH) domain and a microtubule‐binding (GAR) domain and are considered miniversions of spectraplakins. There are four members in the GAS2 family, viz. GAS2, GAS2L1, GAS2L2 and GAS2L3. Although GAS2 is defined as a family of growth arrest–specific proteins, the significant differences in the expression patterns, interaction characteristics and biological issues or diseases among the different GAS2 family members have not been systemically reviewed to date. Therefore, we summarized the available evidence on the structures and functions of GAS2 family members. This review facilitates a comprehensive molecular understanding of the involvement of the GAS2 family members in an array of biological processes, including cytoskeleton reorganization, cell cycle, apoptosis and cancer development.

Gong X, Wang B, Yan L, Lu X, Zhao X. Linalool inhibits the growth of human T cell acute lymphoblastic leukemia cells with involvement of the MAPK signaling pathway. Oncol Lett 2020; 20:181. [PMID: 32934748 PMCID: PMC7471647 DOI: 10.3892/ol.2020.12042] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2019] [Accepted: 07/16/2020] [Indexed: 12/16/2022] Open
Abstract
Linalool can inhibit the malignant proliferation of numerous human malignant solid tumors, including hepatocellular carcinoma, breast cancer, small cell carcinoma and malignant melanoma. However, the role of linalool in T cell acute lymphoblastic leukaemia (T-ALL) remains unclear. In the present study, human T-ALL cell lines (Jurkat, H9, Molt-4 and Raji cells) and peripheral blood mononuclear cells (PBMCs) from healthy donors were treated with various concentrations of linalool (3.75, 7.50, 15.00, 30.00, 60.00 and 120.00 µM, respectively). A CCK-8 assay was used to analyse cell viability and it demonstrated that linalool inhibited the growth of T-ALL cells in a dose-dependent manner, but did not significantly affect normal PBMCs. Flow cytometry was used to detect the cell cycle and apoptosis and demonstrated that linalool reduced the percentage of T-ALL cells at the G0/G1 phase, and induced the apoptosis of T-ALL cells. RNA sequencing was conducted on an Illumina HiSeq X Series 2500 before and after treatment with linalool followed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis. It was demonstrated that the mitogen-activated protein kinase (MAPK) pathway was involved in the effect of linalool on T-ALL cells. Real-time quantitative PCR and western blotting were performed to verify the mRNA and protein levels, respectively of the genes in the signaling pathway identified. In addition, it was found that linalool significantly inhibited phosphorylated (p)-ERK1/2 protein expression and enhanced p-JNK protein expression of T-ALL cells. In conclusion, the present study revealed that linalool inhibits T-ALL cell survival with involvement of the MAPK signaling pathway. JNK activation and ERK inhibition may play a functional role in apoptosis induction of T-ALL cells. Linalool may be developed as a novel anti T-ALL agent.
