Abstract
Purpose Cervical cancer (CC) poses a significant threat to women's health worldwide, and multiple signaling pathways have been confirmed to be involved in its development. The AMPK signaling pathway plays a central role in maintaining energy homeostasis, and its dysregulation is closely associated with the occurrence of CC. Changes in microRNA (miRNA) expression levels might be related to the AMPK signaling pathway. Single nucleotide polymorphisms (SNPs) can affect the function of miRNA and result in the development of CC. To investigate the association between the SNPs of AMPK pathway-associated miRNAs and CC in a Han Chinese population, we selected eight miRNA genes located in the AMPK pathway and analyzed nine SNP loci within these genes to explore whether they are associated with genetic susceptibility to cervical intraepithelial neoplasia (CIN) and CC. Methods A total of 2,220 subjects were included in this study, including 928 healthy controls, 421 CIN patients, and 871 CC patients. Nine candidate SNPs (rs895819 in miR-27a, rs10061133 in miR-449b, rs41291179 in miR-216a, rs76481776 in miR-182, rs10406069 in miR-5196, rs12803915 and rs550894 in miR-612, rs66683138 in miR-3622b, and rs2620381 in miR-627) were genotyped using the TaqMan method. Results The results showed significant differences in the allele distribution of rs41291179 and rs12803915 between the control group and the CIN group, as well as between the control group and the CC group (all P values < 0.005). The A allele of rs41291179 and the G allele of rs12803915 were associated with decreased risk of CIN (OR = 0.05, 95% CI: 0.01-0.39; OR = 0.61, 95% CI: 0.49-0.76) and CC (OR = 0.08, 95% CI: 0.01-0.66; OR = 0.71, 95% CI: 0.59-0.86), respectively. Conclusion Our results suggest that polymorphisms in miRNA genes of the AMPK signaling pathway are associated with the development of CC.

Abstract
This study aimed to examine the expression and biological functions of ACTL6A in glioma cells (U251), the effects of sulforaphane on the growth of U251 cells and the involvement of the ACTL6A/PGK1 pathway in those effects. The U251 cell line was transfected with ACTL6A over-expression plasmids to upregulate the protein, or with ACTL6A inhibitor to underexpress it, then treated with different concentrations of sulforaphane. Cell viability, proliferation, and apoptosis were assessed using standard assays, and levels of mRNAs encoding ACTL6A, PGK1, cyclin D1, Myc, Bax or Bcl-2 were measured using quantitative real-time polymerase chain reaction (qRT-PCR). ACTL6A and PGK1 were expressed at higher levels in glioma cell lines than in normal HEB cells. ACTL6A overexpression upregulated PGK1, whereas ACTL6A inhibition had the opposite effect. ACTL6A overexpression induced proliferation, whereas its inhibition repressed proliferation, enhanced apoptosis, and halted the cell cycle. Moreover, sulforaphane suppressed the growth of U251 cells by inactivating the ACTL6A/PGK1 axis. ACTL6A acts via PGK1 to play a critical role in glioma cell survival and proliferation, and sulforaphane targets it to inhibit glioma.

Abstract
Introduction: Increased Actin-like 6A (ACTL6A) expression is associated with various cancers, but its comprehensive investigation across different malignancies is lacking. We aimed to analyze ACTL6A as a potential oncogene and therapeutic target using bioinformatics tools. Methods: We comprehensively analyzed ACTL6A expression profiles across human malignancies, focusing on correlations with tumor grade, stage, metastasis, and patient survival. Genetic alterations were examined, and the epigenetic landscape of ACTL6A was assessed using rigorous methods. The impact of ACTL6A on immune cell infiltration in the tumor microenvironment was evaluated, along with molecular docking studies and machine learning models. Results: Our analysis revealed elevated ACTL6A expression in various tumors, correlating with poor prognostic indicators such as tumor grade, stage, metastasis, and patient survival. Genetic mutations and epigenetic modifications were identified, along with associations with immune cell infiltration and key cellular pathways. Machine learning models demonstrated ACTL6A's potential for cancer detection. Discussion: ACTL6A emerges as a promising diagnostic and therapeutic target in cancer, with implications for prognosis and therapy. Our study provides comprehensive insights into its carcinogenic actions, highlighting its potential as both a prognostic indicator and a target for anti-cancer therapy. This integrative approach enhances our understanding of ACTL6A's role in cancer pathogenesis and treatment.

Discovery of a proliferation essential gene signature and actin-like 6A as potential biomarkers for predicting prognosis and neoadjuvant chemotherapy response in triple-positive breast cancer. Cancer 2024; 130:1435-1448. [PMID: 38358781 DOI: 10.1002/cncr.35228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 11/27/2023] [Accepted: 12/26/2023] [Indexed: 02/16/2024]
Abstract
BACKGROUND Patients with triple-positive breast cancer (TPBC) have a higher risk of recurrence and lower survival rates than patients with other luminal breast cancers. However, there are few studies on the predictive biomarkers of prognosis and treatment responses in TPBC. METHODS Proliferation essential genes (PEGs) were acquired from clustered regularly interspaced short palindromic repeats-associated protein 9 (CRISPR-Cas9) technology, and cohorts of patients with TPBC were obtained from public databases and our cohort. To develop a TPBC-PEG signature, Cox regression and least absolute shrinkage and selection operator regression analyses were applied. Functional analyses were performed with gene set enrichment analysis. The relationship between candidate genes and neoadjuvant chemotherapy (NACT) sensitivity was explored via real-time quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry (IHC) on the basis of clinical samples. RESULTS Among 900 TPBC-PEGs, 437 showed significant differential expression between TPBC and normal tissues. Three prognostic PEGs (actin-like 6A [ACTL6A], chaperonin containing TCP1 subunit 2 [CCT2], and threonyl-TRNA synthetase [TARS]) were identified and used to construct the PEG signature. Patients with high PEG signature scores exhibited a worse overall survival and lower sensitivity to NACT than patients with low PEG signature scores. RT-qPCR results indicated that ACTL6A and CCT2 expression were significantly upregulated in patients who lacked sensitivity to NACT. IHC results showed that the ACTL6A protein was highly expressed in patients with NACT resistance and nonpathological complete responses. CONCLUSIONS This efficient PEG signature prognostic model can predict the outcomes of TPBC. Furthermore, ACTL6A expression level was associated with the response to NACT, and could serve as an important factor in predicting prognosis and drug sensitivity of patients with TPBC.

Abstract
Clear cell renal cell carcinoma (ccRCC) is the most representative subtype of renal cancer, with a highly aggressive phenotype and extremely poor prognosis. Immune escape is one of the main reasons for ccRCC growth and metastasis, in which circular RNAs (circRNAs) play critical roles. Therefore, this research studied circAGAP1-associated mechanisms in immune escape and distant metastasis in ccRCC. circAGAP1/miR-216a-3p/MKNK2 was overexpressed or down-regulated by cell transfection. EdU assay, colony formation assay, scratch assay, Transwell assay, immunoblotting, and flow cytometry were used to evaluate cell proliferation, migration, invasion, EMT, and immune escape, respectively. Dual-luciferase reporting assay and RIP assay were used to evaluate the targeting relationship between circAGAP1/miR-216a-3p/MKNK2. Xenotransplantation in nude mice was used to evaluate the growth of ccRCC tumors in vivo. Here, circAGAP1 high expression was positively correlated with higher histological grade and distant metastasis and was a prognostic indicator for ccRCC. Depleting circAGAP1 effectively hampered the proliferative, invasive, and migratory capacities, EMT, and immune escape of ccRCC cells. Correspondingly, silencing circAGAP1 delayed tumor growth, distant metastasis, and immune escape in vivo. Mechanistically, circAGAP1 sponged the tumor suppressor miR-216a-3p, thereby preventing miR-216a-3p from inhibiting MAPK2. Collectively, our findings demonstrate that circAGAP1 exerts a tumor suppressor function through miR-216a-3p/MKNK2 during the immune escape and distant metastasis in ccRCC, and suggest that circAGAP1 may be a novel prognostic marker and therapeutic target for ccRCC.

Abstract
Exosomes derived from human umbilical cord mesenchymal stem cells (hucMSCs) could alleviate Alzheimer's disease (AD) defects. Additionally, engineered exosomes are more effective in treating diseases. In this study, we established an in vitro model of AD by treating SH-SY5Y cells with Aβ1-40 . We observed that incubation with hucMSC-derived exosomes effectively protected SH-S5Y5 cells from Aβ1-40 -induced damage. Since NEP plays a central role in suppressing AD development, we screened NEP-targeting miRNAs that are differentially expressed in control and AD patients. We identified miR-211-5p as a potent repressor of NEP expression. Exosomes purified from hucMSCs overexpressing miR-211-5p inhibitor exhibited significantly greater efficiency than control exosomes in mitigating the injury caused by Aβ1-40 treatment. However, this enhanced protective effect was nullified by the knockdown of NEP. These observations demonstrate that inhibition of miR-211-5p has the potential to improve the efficacy of hucMSC-derived exosomes in AD treatment by increasing NEP expression.

Abstract
ETS1, an important member of the ETS transcription factor family, is involved in a variety of physiological processes in living organisms, such as cell development, differentiation, proliferation and apoptosis, and is thought to be associated with embryonic development and reproduction. However, the polymorphism of ETS1 has been rarely studied, and its potential impact on the formation of reproductive traits in sheep remains unclear. Here, we first analyzed polymorphisms of ETS1 in a population of 382 small-tailed Han sheep with a lambing number record using the Kompetitive Allele Specific PCR (KASP) technique. The results showed the presence of a SNP locus rs161611767 (T > C) in the 3'UTR of ETS1. The association analysis showed the lambing number of first, second and third parity in the individuals with the CC genotype (2.51 ± 0.108, 2.51 ± 0.179, 1.27 ± 0.196) was higher than that of individuals with the TT genotype (1.79 ± 0.086, 1.56 ± 0.102, 0.56 ± 0.100) (P < 0.05). Then, molecular biotechnologies were used to investigate the effects of the EST1 rs161611767 mutant locus on host gene expression in sheep and the underlying mechanism of its effect on sheep reproduction. The RT‒qPCR results showed that the expression of ETS1 was higher in individuals with the CC genotype than in those with the TT genotype (P < 0.05). The dual luciferase reporter assay showed that the luciferase activity of ETS1 in sheep with the TT genotype was decreased compared to CC genotype (P < 0.05), confirming the existence of EST1 rs161611767 in the 3'UTR as a functional SNP. Given that the 3'UTR is an important regulatory region of gene transcription and translation, we performed bioinformatics prediction and confirmed that the SNP rs161611767 of ETS1 was a direct functional target of miR-216a-3p using dual luciferase activity assay, and the binding capacity of allele T was stronger than that of allele C. Subsequently, the cell transfection results showed that miR-216a-3p suppressed the endogenous expression of ETS1 in sheep primary granulosa cells (GCs). Finally, CCK-8, EdU, WB detection of marker proteins and flow cytometry were used to detect the effects of miR-216a-3p on GCs viability and proliferation/apoptosis, respectively. The results showed that miR-216a-3p inhibited the proliferation of GCs while promoting apoptosis of GCs. In conclusion, these results demonstrate that the SNP rs161611767 of ETS1 is associated with lambing number in small-tailed Han sheep, and miR-216a-3p can act as a regulatory element binding to the T mutation in rs161611767 to regulate ETS1 expression and affect GCs development, which may indirectly affect the number of lambs in sheep. These studies provide evidence for the involvement of ETS1 polymorphisms in sheep reproduction and are expected to provide new insights to elucidate the molecular genetic mechanisms of lambing traits in sheep.

Abstract
MicroRNAs (miRNAs) as the members of non-coding RNAs family are involved in post-transcriptional regulation by translational inhibiting or mRNA degradation. They have a critical role in regulation of cell proliferation and migration. MiRNAs aberrations have been reported in various cancers. Considering the importance of these factors in regulation of cellular processes and their high stability in body fluids, these factors can be suggested as suitable non-invasive markers for the cancer diagnosis. MiR-216a deregulation has been frequently reported in different cancers. Therefore, in the present review we discussed the molecular mechanisms of the miR-216a during tumor progression. It has been reported that miR-216a mainly functioned as a tumor suppressor through the regulation of signaling pathways and transcription factors. This review paves the way to suggest the miR-216a as a probable therapeutic and diagnostic target in cancer patients.

Si C, Yang L, Cai X. LncRNA LINC00649 aggravates the progression of cervical cancer through sponging miR-216a-3p. J Obstet Gynaecol Res 2022; 48:2853-2862. [PMID: 36054700 DOI: 10.1111/jog.15405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 07/14/2022] [Accepted: 08/11/2022] [Indexed: 11/30/2022]
Abstract
AIM Increasing studies have revealed the participation of lncRNAs in the occurrence and development of cervical cancer. This study explored the influence of lncRNA LINC00649 in cervical cancer. METHODS Expression of LINC00649 and miR-216a-3p in cervical cancer was detected by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR). The Kaplan-Meier curve and Cox regression analyses were conducted to evaluate the clinical value of LINC00649 in cervical cancer. The roles of LINC00649 in cervical cancer cells were detected by transfecting siRNA through cellular function assays. RESULTS LINC00649 expression was increased in cervical cancer tissues, especially in squamous histology, positive lymph node metastasis, and high-FIGO stage tissues. The higher expression of LINC00649 predicted a shorter survival rate for patients. LINC00649 could bind directly with miR-216a-3p. Silence of LINC00649 could enhance the expression of miR-216a-3p and suppress the cervical cancer cell proliferation abilities, migration capacities, and invasion power. Whereas, transfection of miR-216a-3p inhibitor partially reverses the above cellular activities changes in cervical cancer cells. CONCLUSIONS The LINC00649 expression may act as a prognostic predictor and may aggravate cervical cancer progression by targeting miR-216a-3p, providing potential therapeutic targets for patients with cervical cancer.

Abstract
The Hippo signaling pathway was found coordinately modulates cell regeneration and organ size. Its dysregulation contributes to uncontrolled cell proliferation and malignant transformation. YAP/TAZ are two critical effectors of the Hippo pathway and have been demonstrated essential for the initiation or growth of most tumors. Noncoding RNAs (ncRNAs), including miRNAs, lncRNAs, and circRNAs, have been shown to play critical roles in the development of many cancers. In the past few decades, a growing number of studies have revealed that ncRNAs can directly or indirectly regulate YAP/TAZ signaling. YAP/TAZ also regulate ncRNAs expression in return. This review summarizes the interactions between YAP/TAZ signaling and noncoding RNAs together with their biological functions on cancer progression. We also try to describe the complex feedback loop existing between these components.

Abstract
Papillary thyroid cancer (PTC) remains the most common endocrine malignancy, despite marked achieves in recent decades, and the mechanisms underlying the pathogenesis and progression for PTC are incompletely elucidated. Accumulating evidence show that γ-glutamylcyclotransferase (GGCT), an enzyme participating in glutathione homeostasis and is elevated in multiple types of tumors, represents an attractive therapeutic target. Using bioinformatics, immunohistochemistry, qRT-PCR, and Western blot assays, we found that GGCT expression was upregulated in PTC and correlated with more aggressive clinicopathological characteristics and worse prognosis. GGCT knockdown inhibited the growth and metastasis ability of PTC cells both in vitro and in vivo and reduced the expression of mesenchymal markers (N-cadherin, CD44, MMP2, and MMP9) while increasing epithelial marker (E-cadherin) in PTC cells. We confirmed binding of microRNA-205-5p (miR-205-5p) on the 3'-UTR regions of GGCT by dual-luciferase reporter assay and RNA-RNA pull-down assay. Delivery of miR-205-5p reversed the pro-malignant capacity of GGCT both in vitro and in vivo. Lastly, we found that GGCT interacted with and stabilized CD44 in PTC cells by co-immunoprecipitation and immunohistochemistry assays. Our findings illustrate a novel signaling pathway, miR-205-5p/GGCT/CD44, that involves in the carcinogenesis and progression of PTC. Development of miR-205-mimics or GGCT inhibitors as potential therapeutics for PTC may have remarkable applications.

Abstract
As the fourth commonest malignancy among females worldwide, cervical cancer (CC) poses a huge challenge to human health. The pivotal regulatory roles of lncRNAs in cancers have been highlighted. LOXL1 antisense RNA 1 (LOXL1-AS1) has been reported to play a key role in cervical squamous cell carcinoma and other various cancers. Thus, we investigated the roles and mechanisms of lncRNA LOXL1-AS1 in CC. The in vivo experiments demonstrated that LOXL1-AS1 downregulation inhibited tumor growth and metastasis and proliferation of CC cells. The results of RT-qPCR demonstrated that LOXL1-AS1 and ectodermal-neural cortex 1 (ENC1) expression levels were upregulated in CC cells and tissues, while microRNA-423-5p (miR-423-5p) level was downregulated. As subcellular fractionation assays, RNA pull down assays and luciferase reporter assays revealed, LOXL1-AS1 bound to miR-423-5p and miR-423-5p targeted ENC1. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, wound healing and colony formation assays demonstrated that miR-423-5p upregulation and LOXL1-AS1 downregulation inhibited CC cell proliferation and migration, while ENC1 upregulation attenuated the inhibitory effects of miR-423-5p upregulation on the malignant phenotypes of CC cells. Western blotting was conducted to measure protein levels and the results showed that ENC1 knockdown inhibited the activation of ERK/MEK pathway. In summary, the LOXL1-AS1/miR-423-5p/ENC1 axis accelerates CC development through the MEK/ERK pathway.

Abstract
Purpose Actin-like 6A (ACTL6A), a regulatory subunit of the ATP-dependent chromatin-remodeling complex SWI/SNF, acts as an oncogenic factor. This study is aimed at evaluating the correlation between ACTL6A expression and clinicopathological parameters in pancreatic cancer (PC) patients. Methods The differences of Actl6a mRNA expression between PC tissues and normal pancreatic tissues were analyzed in public databases, and ACTL6A expression was then determined and confirmed in 60 paired tissue specimens using immunohistochemistry staining. The association analysis between ACTL6A expression and the clinicopathological characteristics was analyzed, as well as Kaplan–Meier survival analysis. Univariate and multivariate Cox analyses were performed to identify the prognostic factors in the overall survival (OS) of patients with PC. Results The mRNA expression of Actl6a showed significantly higher in PC compared to normal controls (p < 0.05) from public databases. The score of immunohistochemistry staining further confirmed that ACTL6A expression was significantly upregulated in PC tissues (p < 0.001) through immunohistochemistry staining. High ACTL6A expression was associated with lymphovascular space invasion of PC. Kaplan–Meier analysis revealed that the high expression of ACTL6A was markedly associated with poor OS. Moreover, univariate and multivariate analysis demonstrated that ACTL6A acted as an independent risk factor for PC prognosis. Conclusion ACTL6A is upregulated in PC and acts as a risk factor for poor prognosis in patients with PC, and therefore clinicians could around it design preventive measures and individualized treatment to improve mortality in patients with PC.

Abstract
Recently, long noncoding RNAs (lncRNAs) have been revealed to participate in cancer therapy. Especial in tumor radiotherapy, lncRNAs usually could enhance or restrict the radiosensitivity in different ways. LncRNA HCP5 is highly expressed in esophageal cancer and influenced the malignant behaviors of esophageal cancer cells. However, this study dedicates to clarify if lncRNA HCP5 affects the radiosensitivity of esophageal carcinoma. The expression levels of HCP5 in esophageal cancer and adjacent noncancerous tissue were first analyzed on the TCGA database and then detected by qRT-PCR. The related functional experiments were used to investigate whether the radiosensitivity of esophageal squamous cell carcinoma was affected by the inhibition of HCP5. The expression results showed HCP5 is upregulated in esophageal cancers compared to the normal tissues. Meanwhile, knockdown HCP5 further suppressed the proliferation and promoted the apoptosis of esophageal cancer cells treated with a 2 Gy dose of radiotherapy. Moreover, we uncovered that knockdown HCP5 eliminated radiotherapy resistance by modulating the miR-216a-3p/PDK1 axis to inhibit the AKT activation. Finally, rescue experiments pointed that lowering the miR-216a-3p expression weakened the inhibition effect of knockdown HCP5 on cells treated with radiotherapy. To summary, our results indicate that HCP5 is involved in esophageal carcinoma radiotherapy and knockdown HCP5 enhances the radiosensitivity of esophageal carcinoma by modulating AKT signaling activation.

Abstract
The long non-coding RNA, urothelial cancer-associated 1 (UCA1) is an important regulator in several tumors. However, to the best of our knowledge, the clinical roles of UCA1 in cervical cancer remain unclear. Thus, the present study aimed to investigate the function and mechanism of UCA1 in cervical cancer. Reverse transcription-quantitative PCR analysis was performed to detect UCA1 and microRNA (miR)-299-3p expression in cervical cancer tissues and cell lines. The Cell Counting Kit-8 and Transwell assays were performed to assess cell proliferation and invasion, respectively. Furthermore, the dual-luciferase reporter assay was performed to confirm the association between UCA1 and miR-299-3p. Rescue experiments were performed to determine the mechanism of the UCA1/miR-299-3p axis. The results demonstrated that UCA1 expression was upregulated in cervical cancer tissues and cell lines. Furthermore, overexpression of UCA1 enhanced the proliferation and invasion of cervical cancer cells, the effects of which were reversed following UCA1 knockdown. Notably, UCA1 interacted with miR-299-3p and negatively regulated miR-299-3p expression. In addition, miR-299-3p expression was downregulated in cervical cancer tissues and cell lines. Overexpression of miR-299-3p suppressed the proliferation and invasion of cervical cancer cells, reversing the effects of UCA1 knockdown on cervical cancer cell proliferation. Taken together, the results of the present study suggest that UCA1 promotes cell proliferation and invasion by regulating miR-299-3p expression in cervical cancer.

Abstract
Accumulating evidence shows that microRNAs (miRNAs) play key roles in tumorigenesis, progression, recurrence and drug resistance of malignant tumors. The tumor-promoting role of miR-552 has been evidenced in multiple tumors. Yet, the relevance of miR-552 in cervical cancer remains undetermined. This study aimed to investigate the role of miR-552 in cervical cancer proliferation and metastasis. Herein, we for first found that miR-552 expression was upregulated in cervical cancer tissues compared with their normal controls. Functional assays revealed that miR-552 promoted the proliferation and metastasis of cervical cancer cells. Mechanically, bioinformatics and luciferase reporter analysis identified MUC15 as a direct target of miR-552. Reduced MUC15 expression was detected in cervical cancer, and MUC15 overexpression exhibited a tumor-suppressive effect. MUC15 restoration partially abolished the discrepancy of growth and metastasis capacity between miR-552 overexpression cervical cancer cells and control cells. Taken together, these data demonstrate that miR-552 acts as a potential oncogene miRNA in cervical cancer, which exerts its function through targeting MUC15.

Abstract
This work investigates the effect of circABCC4 on the proliferation, migration, and invasion of colorectal cancer SW620 cells; circABCC4’s regulation of miR-216a-3p is also studied. qRT-PCR was used to measure the levels of circABCC4 and miR-216a-3p in colorectal cancer and adjacent
tissues. The human colorectal cancer SW620 cells were transfected with different constructs of circABCC4 or miR-216a-3p or both to study their interactions and combined effects on cell behavior. A dual-luciferase reporter experiment tested the targeted relationship between circABCC4 to miR-216a-3p.
Furthermore, the behaviors of SW620 cells, such as cell viability, migration, and invasion, were investigated. Also, the proteins related to cell behaviors were investigated with western blotting. Our results showed that colorectal cancer tissues had a higher level of circABCC4 but a lower
level miR-216a-3p. The increased level of circABCC4 and the reduced level of miR-216a-3p had analogous influences on the behaviors of SW620 cells, resulting in reduced cell proliferation, migration, and invasion; the levels of related protein were also decreased. Moreover, we found that disrupting
miR-548c-3p could reverse the influence of inhibiting circABCC4 on SW620 cells. In addition, the dual-luciferase reporter assay results confirmed the targeting of miR-216a-3p by circABCC4. These data demonstrate that the silencing of circABCC4 may inhibit the proliferation, migration, and
invasion of colorectal cancer cells by upregulating miR-548c-3p.

Abstract
Background Long non-coding RNAs (lncRNAs) FOXD2 adjacent opposite strand RNA 1 (FOXD2-AS1) are reported could function as tumor promoter in several cancers. However, its role in hemangioma was not reported to yet. Methods Expression level of FOXD2-AS1 in hemangioma tissues and cells was explored using quantitative reverse-time PCR. Cell counting kit-8 (CCK-8) assay, colony formation assay, wound-healing assay, and transwell invasion assay were conducted to measure the roles of FOXD2-AS1. In addition, the levels of markers for proliferation and Epithelial-Mesenchymal Transition were investigated. Connection of FOXD2-AS1 and mcroRNA-324-3p (miR-324-3p) or miR-324-3p and p53 and DNA damage regulated 1 (PDRG1) was analyzed with bioinformatic analysis method and dual-luciferase activity reporter assay. Results Here, we found that FOXD2-AS1 was highly expressed in proliferating-phase hemangioma tissues compared with the involuting-phase hemangioma tissues. Functionally, FOXD2-AS1 knockdown suppressed cell proliferation, colony formation, migration, and invasion in vitro. Conversely, overexpression of FOXD2-AS1 promoted tumor growth in vitro. Mechanistically, FOXD2-AS1 inversely regulated miR-324-3p abundance in hemangioma cells. We also found FOXD2-AS1 acted as a competing endogenous RNA (ceRNA) by directly sponging miR-324-3p to regulate PDRG1 expression. In addition, the knockdown of PDRG1 reversed the stimulation effects of FOXD2-AS1 overexpression on HA cells. Conclusion To conclude, our study sheds novel light on the biological roles of FOXD2-AS1 in hemangioma, which may help the development of targeted therapy method for cancer.
