Abstract
Heart and neural crest derivatives expressed transcript 2 (HAND2) is a critical mediator of progesterone action in endometrial stromal cells. Silencing of Hand2 expression in mouse uterus leads to an unopposed FGFR-mediated action that causes female mice infertility. To investigate the involvement of HAND2-FGFR signaling in pathogenesis of adenomyosis, immunohistochemistry, in situ hybridization, and quantitative real-time PCR were employed to assess gene expression in the normal endometrium, the paired eutopic endometrium and ectopic lesions obtained from women with adenomyosis. DNA methylation in the regions of HAND2 promoter and the first exon was also monitored in these samples. Our results revealed that HAND2 expression were dramatically reduced, but FGF9 expression and FGFR-ERK1/2-mediated MAPK signaling pathway were enhanced in the eutopic endometrium and ectopic lesions of patients with adenomyosis compared to the normal controls. Interestingly, expression of HAND2-AS1, a long noncoding RNA that resides adjacent to HAND2 in genome, was also reduced in adenomyosis. DNA methylation analysis revealed that the bidirectional promoter between HAND2 and HAND2-AS1, and the first exon of HAND2 gene was heavily methylated in the eutopic endometrium and the ectopic lesions of adenomyosis. To investigate the regulation of gene expression by HAND2-AS1, HAND2-AS1 expression was silenced in human endometrial stromal cells. In contrast to the downregulation of HAND2 in response to HAND2-AS1 silencing, FGF9 expression was augmented significantly. Endometrial stromal cells lacking HAND2-AS1 exhibited enhanced proliferation and migration potentials. Collectively, our studies revealed a new molecular mechanism by which HAND2-AS1 is involved in the pathogenesis of adenomyosis via modulating HAND2-FGFR-mediated signaling.

Abstract
OBJECTIVE Acute coronary syndrome (ACS) is an emergency and severe disorder of the cardiovascular system. This paper assessed the expression of plasma HAND2-AS1 in patients with ACS, researched its diagnostic and prognostic significance, and studied its possible mechanism for participating in ACS. METHODS The concentration of HAND2-AS1 of 101 included patients with ACS was certified by qRT-PCR and its possible diagnostic function was revealed by the receiver operating characteristic (ROC) curve. All patients were followed up for 6 months after percutaneous coronary intervention (PCI) therapy and Kaplan-Meier (K-M) curve and COX regression analysis was performed to estimate the short-term prognostic value of HAND2-AS1 in ACS. The interrelationship between HAND2-AS1 and Gensini score and endothelial injury was identified via Pearson correlation. The function of HAND2-AS1 on the viability, migration, and apoptosis of human umbilical vein endothelial cells (HUVECs) was estimated by the Cell Counting Kit-8 (CCK-8), Transwell chamber, and flow cytometry. RESULTS In ACS patients, the expression of serum HAND2-AS1 was prominently decreased and closely correlated with the Gensini score. The decreased HAND2-AS1 expression was of diagnostic significance. Declined plasma HAND2-AS1 was observed in patients with the major adverse cardio-cerebrovascular event (MACCE) and was an independent risk for the poor prognosis of ACS patients. In the cell model, upregulation of HAND2-AS1 improved cell viability and migration and inhibited cell apoptosis. CONCLUSION HAND2-AS1 was an independent biomarker for the diagnosis and prognosis of ACS. HAND2-AS1 might be involved in ACS development by regulating endothelial damage.

Abstract
The HAND2-AS1 (HAND2 Antisense RNA 1) Long noncoding RNA (lncRNA) has emerged as a participant in the initiation of various cancer types, underscoring its pivotal involvement in both oncological processes and immune responses. To gain deeper insights into the functional nuances of HAND2-AS1 and identify novel avenues for cancer immunotherapy, a comprehensive evaluation of this gene was undertaken. Here, based on the co-expression network analysis and construction of interacting lncRNA-mRNA genes, we introduce the HAND2-AS1 lncRNA, emphasizing its key roles in tumorigenesis and immune regulation. Our study spans across 33 distinct cancer types, revealing the HAND2-AS1's aberrant expression patterns, methylation variations, mutational signatures, and immune engagement. Across a majority of tumors, HAND2-AS1 exhibited a propensity for down-regulation, remarkably an association with poor survival outcomes. The outcomes of functional enrichment analyses strongly suggest HAND2-AS1's engagement in tumor progression and its association with various immune pathways across diverse tumor classifications. Additionally, a positive correlation emerged between HAND2-AS1 expression and the infiltration levels of key immune cells, encompassing not only immunosuppressive entities such as tumor-associated macrophages, cancer-associated fibroblasts, and Tregs, but also immune effector cells like NK cells and CD8+ T cells, spanning a pan-cancer context. Furthermore, the differential expression of HAND2-AS1 appears to have downstream consequences on various pathways, thus implicating it as a potential regulator in diverse cancer types. Finally, we have employed CRC tumor and normal samples to carry out clinical validation of HAND2-AS1. Our study unveils HAND2-AS1's potential as a pan-cancer tumor suppressor, and its essential role in the tumorigenesis and immune surveillance. The increased HAND2-AS1 expression emerges as a promising candidate for prognostic evaluation, therapeutic strategy, and a focal point for immunotherapeutic interventions.

Abstract
We previously developed several successful decellularization strategies that yielded porcine cardiac extracellular matrices (pcECMs) exhibiting tissue-specific bioactivity and bioinductive capacity when cultured with various pluripotent and multipotent stem cells. Here, we study the tissue-specific effects of the pcECM on seeded human mesenchymal stem cell (hMSC) phenotypes using reverse transcribed quantitative polymerase chain reaction (RT-qPCR) arrays for cardiovascular related gene expression. We further corroborated interesting findings at the protein level (flow cytometry and immunological stains) as well as bioinformatically using several mRNA sequencing and protein databases of normal and pathologic adult and embryonic (organogenesis stage) tissue expression. We discovered that upon the seeding of hMSCs on the pcECM, they displayed a partial mesenchymal-to-epithelial transition (MET) toward endothelial phenotypes (CD31+) and morphologies, which were preceded by an early spike (~Day 3 onward after seeding) in HAND2 expression at both the mRNA and protein levels compared to that in plate controls. The CRISPR-Cas9 knockout (KO) of HAND2 and its associated antisense long non-coding RNA (HAND2-AS1) regulatory region resulted in proliferation arrest, hypertrophy, and senescent-like morphology. Bioinformatic analyses revealed that HAND2 and HAND2-AS1 are highly correlated in expression and are expressed in many different tissue types albeit at distinct yet tightly regulated expression levels. Deviation (downregulation or upregulation) from these basal tissue expression levels is associated with a long list of pathologies. We thus suggest that HAND2 expression levels may possibly fine-tune hMSCs' plasticity through affecting senescence and mesenchymal-to-epithelial transition states, through yet unknown mechanisms. Targeting this pathway may open up a promising new therapeutic approach for a wide range of diseases, including cancer, degenerative disorders, and aging. Nevertheless, further investigation is required to validate these findings and better understand the molecular players involved, potential inducers and inhibitors of this pathway, and eventually potential therapeutic applications.

Abstract
HAND2 antisense RNA 1 (HAND2-AS1) is a newly recognized lncRNA encoded by a gene on 4q34.1. This lncRNA has 10 exons and is predicted to have a positive effect on expression of certain genes. HAND2-AS1 is mainly considered as a tumor suppressive lncRNA in different tissues. Moreover, HAND2-AS1 has been shown to regulate expression of several targets with possible roles in the carcinogenesis through serving as a sponge for miRNAs. This lncRNA can also influence activity of BMP, TGF-β1, JAK/STAT and PI3K/Akt pathways. Down-regulation of HAND2-AS1 in tumor tissues has been associated with larger tumor size, higher tumor grade, higher chance of metastasis and poor clinical outcome. The present study aims at summarization of the impact of HAND2-AS1 in the carcinogenesis and its potential in cancer diagnosis or prediction of cancer prognosis.

Abstract
Long non-coding RNAs (LncRNAs) are single-stranded RNAs over 200 nucleotides in length that have no protein-coding function and have long been considered non-functional by-products of transcription. Recent studies have shown that dysregulation of lncRNAs may be involved in the malignant biological behavior of tumors. Targeted regulation of lncRNAs has become a research focus of anti-tumor treatment. LncRNAs heart and neural crest derivatives expressed 2 antisense RNA 1 (HAND2-AS1) was down-regulated in various tumors and can be used as a critical tumor regulator to modulate tumor cells proliferation, apoptosis, metastasis, invasion, metabolism and drug resistance. Additionally, aberrantly expressed HAND2-AS1 was closely related to the clinical pathological characteristics of cancer patients and serve as a promising tumor diagnostic and prognostic biomarker. This article aims to review the roles of HAND2-AS1 in tumorigenesis and development, as well as the underlying molecular mechanisms and clinical significance.

Abstract
Genetic variants in several long noncoding RNA genes have been implicated in the occurrence and development of colorectal cancer (CRC). In this study, we explored the association between HAND2-AS1 gene rs2276941 polymorphism and the risk and clinical stage of CRC. A direct sequencing method was used to detect the rs2276941 polymorphism in 576 CRC patients and 864 healthy individuals. Real-time quantitative PCR technology was used to explore the expression of HAND2-AS1 and hsa-miR-1275 in colorectal tissues with different rs2276941 genotypes. Dual-luciferase reporter assay was used to assess the function of the rs2276941 polymorphism. We found that the rs2276941 polymorphism was associated with a decreased risk of CRC (TT vs. CC, OR = 0.38, 95% CI = 0.16-0.89, p = 0.03; TT vs. [CC+CT], OR = 0.40, 95% CI = 0.17-0.94, p = 0.03). Furthermore, a significant negative correlation was observed between the expression of HAND2-AS1 and hsa-miR-1275 in colorectal tissues with rs2276941 TT genotype. Functional experimental results showed that the rs2276941 T allele might promote the binding of HAND2-AS1 to hsa-miR-1275. The current study results suggested that HAND2-AS1 gene rs2276941 polymorphism affecting the binding of hsa-miR-1275 was associated with CRC risk and might serve as a CRC susceptibility biomarker.

Abstract
The abnormally expressed long non-coding RNAs (lncRNAs) exert an important part in the occurrence and development of cardiovascular disease, however, their roles in atherosclerosis (AS) remains unknown. This work focused on investigating the role of HAND2 Antisense RNA 1 (HAND2-AS1) and the related mechanism. As a result, SIRT1 and HAND2-AS1 expression significantly decreased in plasma from patients with atherosclerotic plaques and macrophages originating from THP-1 induced by ox-LDL. Lentivirus mediated HAND2-AS1 overexpression markedly inhibited lipid absorption and deposition within foam cells originating from THP-1 macrophages. HAND2-AS1 endogenously sponged miR-128 and suppressed its activity via sequence complementation. Furthermore, HAND2-AS1 enhanced the expression of SIRT1 via binding to miR-128, thereby promoting ABCA1/G1 expression. Altogether, HAND2-AS1 targeting miR-1208/SIRT1 axis alleviates the formation of foam cells within AS. Besides, HAND2-AS1 may be used to be the possible anti-AS therapeutic target.

Abstract
Background Long non-coding RNA heart and neural crest derivatives expressed 2-antisense RNA 1 (HAND2-AS1) was found to be elevated in rheumatoid arthritis (RA) fibroblast-like synoviocytes (RA-FLSs). However, whether HAND2-AS1 functions as an exosomal lncRNA related to mesenchymal stem cells (MSCs) in RA progression is unknown. Methods The expression of HAND2-AS1, microRNA (miR)-143-3p, and tumor necrosis factor alpha-inducible protein 3 (TNFAIP3) was detected using quantitative real-time polymerase chain reaction and Western blot. Cell proliferation, apoptosis, migration, and invasion were detected using cell counting kit-8, flow cytometry, and wound healing and transwell assays. The levels of tumor necrosis factor-α (TNF-α) and interleukins (IL)-6 were analyzed using enzyme-linked immunosorbent assay. The level of phosphorylated-p65 was examined by Western blot. The binding interaction between miR-143-3p and HAND2-AS1 or TNFAIP3 was confirmed by the dual-luciferase reporter and RIP assays. Exosomes were isolated by ultracentrifugation and qualified by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and Western blot. Results HAND2-AS1 was lowly expressed in RA synovial tissues, and HAND2-AS1 re-expression suppressed the proliferation, motility, and inflammation and triggered the apoptosis in RA-FLSs via the inactivation of NF-κB pathway. Mechanistically, HAND2-AS1 directly sponged miR-143-3p and positively regulated TNFAIP3 expression, the target of miR-143-3p. Moreover, the effects of HAND2-AS1 on RA-FLSs were partially attenuated by miR-143-3p upregulation or TNFAIP3 knockdown. HAND2-AS1 could be packaged into hMSC-derived exosomes and absorbed by RA-FLSs, and human MSC-derived exosomal HAND2-AS1 also repressed above malignant biological behavior of RA-FLSs. Conclusion MSC-derived exosomes participated in the intercellular transfer of HAND2-AS1 and suppressed the activation of RA-FLSs via miR-143-3p/TNFAIP3/NF-κB pathway, which provided a novel insight into the pathogenesis and treatment of RA.

Abstract
Increasing evidence showed that Heart and Neural Crest Derivatives Expressed 2 antisense RNA 1 (HAND2-AS1) was involved in the progression of several cancers, but its expression and function in gastric cancer (GC) was rarely reported. HAND2-AS1 expression in GC tissues and cells was detected at first. Cell function assays were performed to investigate the biological roles of HAND2-AS1 in GC cells. Moreover, the genes regulated by HAND2-AS1 in GC were investigated. Downregulation of HAND2-AS1 was found in GC tissues and cell lines. HAND2-AS1 overexpression inhibited GC cell proliferation, invasion, and arrested cell cycle at G0/G1 phase, whereas HADN2-AS1 knockdown significantly promoted cell proliferation and invasion. Bioinformatic analysis showed there is a potential HADN2-AS1/microRNA-769-5p (miR-769-5p)/transcription elongation factor A like 7 (TCEAL7) axis in GC. Luciferase activity reporter system was used to confirm this link. Taken together, our study showed that HAND2-AS1 exerts its tumor suppressive role in GC via regulating miR-769-5p/TCEAL7.

Abstract
Background: Triple-negative breast cancer (TNBC) is a special type of breast cancer, its tumor cell metastasis rate is much higher than other types, and at the same time has a high rate of postoperative recurrence, which significantly threatens the health of women. Thus, it is urgent to explore a new treatment for TNBC. Results: MiR-106a-5p was up-regulated in TNBC tissues and cells, and was positively correlated with the tumor grade, which indicated poor prognosis in TNBC patients. Mesenchymal stem cells (MSCs) can transport miR-106a-5p into TNBC cells via exosomes. Functional analysis showed exo-miR-106a-5p secreted by MSCs promoted tumor progression in TNBC cells. Furthermore, lncRNA HAND2-AS1 inhibited miR-106a-5p levels, and HAND2-AS1 was decreased in TNBC tissues and cells. Besides, overexpression of HAND2-AS1 reduced the secretion of exo-miR-106a-5p secretion from MSCs, thus suppressed TNBC development. Conclusion: Our study revealed that HAND2-AS1 inhibited the growth of TNBC, which were mediated by the inhibitory effects of MSC-derived exosomal miR-106a-5p.

Abstract
Objective: lncRNA HAND2 antisense RNA 1 (HAND2-AS1) is consistently well recognized to suppress multiple tumors, while its function was uncertified in liver cancer. Materials and Methods: qRT-PCR analysis and TCGA database discovered the expression in liver cancer. CCK-8 and Transwell migration assay demonstrated the impact of HAND2-AS1 on cell proliferation and migration. Bioinformatic analysis and luciferase reporter assay were utilized to monitor the binding between HAND2-AS1 or SOCS5 mRNA and miR-3118. The function of SOCS5 on inactivating the JAK-STAT pathway was confirmed through Western blot assays. Rescue experiments unmasked that HAND2-AS1-mediated SOCS5 affected cell proliferation and migration through the JAK-STAT pathway in liver cancer. Results: The authors discovered the downregulated HAND2-AS1 in liver cancer cells. HAND2-AS1 augmentation apparently impaired the capacity of liver cancer viability, proliferation, and migration. Cytoplasmic HAND2-AS1 directly bound to miR-3118 and released SOCS5, leading to upregulation of SOCS5. Next, the negative regulator role of SOCS5 in the adjusting JAK-STAT pathway was reconfirmed in this study. Conclusions: HAND2-AS1 enhanced inactivation of the JAK-STAT pathway through sponging miR-3118 and facilitating SOCS5 to retard cell proliferation and migration in liver cancer.

Abstract
Long noncoding RNAs (lncRNAs) are molecules more than 200 nucleotides in length. They play roles in various cells, mainly regulating cell growth, differentiation, and apoptosis. They also participate in the pathogenesis of many diseases. In fact, several studies have shown that lncRNAs function as cancer or tumor suppressor genes and play important roles in the occurrence and development of cancer in humans. New evidence has shown that lncRNA heart and neural crest derivatives expressed 2-antisense RNA 1 (lncRNA HAND2-AS1) hinders the occurrence and development of various tumors. Overexpression of HAND2-AS1 was found to be significantly related to the clinical and pathological characteristics of cancer patients, as well as the regulation of cell proliferation, apoptosis, invasion, metastasis, and energy metabolism through several possible mechanisms. Therefore, HAND2-AS1 may be a promising tumor biomarker and therapeutic target. Here, we review the biological functions, mechanisms, and potential clinical significance of HAND2-AS1 in numerous human tumors.

Abstract
Long non-coding RNAs (lncRNAs) are increasingly being identified as crucial regulators in pathologies like cancer. High-grade serous ovarian carcinoma (HGSC) is the most common subtype of ovarian cancer (OC), one of the most lethal gynecological malignancies. LncRNAs, especially in cancers such as HGSC, could play a valuable role in diagnosis and even therapy. From RNA-sequencing analysis performed between an OC cell line, SKOV3, and a Fallopian Tube (FT) cell line, FT194, an important long non-coding RNA, HAND2 Anti sense RNA 1 (HAND2-AS1), was observed to be significantly downregulated in OCs when compared to FT. Its downregulation in HGSC was validated in different datasets and in a panel of HGSC cell lines. Furthermore, this study shows that the downregulation of HAND2-AS1 is caused by promoter hypermethylation in HGSC and behaves as a tumor suppressor in HGSC cell lines. Since therapeutic relevance is of key importance in HGSC research, for the first time, HAND2-AS1 upregulation was demonstrated to be one of the mechanisms through which HDAC inhibitor Panobinostat could be used in a strategy to increase HGSC cells’ sensitivity to chemotherapeutic agents currently used in clinical trials. To unravel the mechanism by which HAND2-AS1 exerts its role, an in silico mRNA network was constructed using mRNAs whose expressions were positively and negatively correlated with this lncRNA in HGSC. Finally, a putative ceRNA network with possible miRNA targets of HAND2-AS1 and their mRNA targets was constructed, and the enriched Gene Ontology (GO) biological processes and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were identified.

Abstract
Introduction Increasing evidence has shown that abnormally expressed long non-coding RNA (lncRNA) plays crucial roles in prostate cancer (PCa) progression. Materials and Methods Here, we analyzed the expression level of lncRNA HAND2 antisense RNA 1 (HAND2-AS1) in PCa cells and tissues. Function assays were performed to investigate the biological roles of HAND2-AS1 in PCa cell behaviors. Bioinformatics methods, luciferase activity reporter assay, and RNA pull-down assay were performed to validate the connection of microRNA-106a-5p (miR-106a-5p) with HAND2-AS1. Also, the target of miR-106a-5p was explored using the same methods. Results Our results revealed HAND2-AS1 expression was decreased in both PCa cells and tissues. In vitro functional assays showed HAND2-AS1 could inhibit PCa cell proliferation and colony formation through promoting cell apoptosis. Dual-luciferase activity assays showed miR-106a-5p could directly bind with HAND2-AS1 and RNA binding motif protein 24 (RBM24). Mechanistically, we showed that HAND2-AS1 regulates PCa cell behaviors via targeting miR-106a-5p/RBM24 axis. Conclusion In summary, our results illustrated that HAND2-AS1 functions as miR-106a-5p sponge to regulate RBM24 expression, and to influence PCa progression.

Abstract
Cervical cancer is one of the major malignancies, the pathophysiology and progression of which remain to be scarcely understood. Long non-coding RNAs (lncRNAs) have been previously implicated in the progression of cervical cancer. Here, the purpose of this study was to identify whether lncRNA heart- and neural crest derivative-expressed 2-antisense RNA 1 (HAND2-AS1) affect the development of cervical cancer through regulation of chromosome 16 open reading frame 74 (C16orf74) by mediating a transcription factor E2F4. RT-qPCR was performed to determine the expression of HAND2-AS1 in cervical cancer cells. Then, cervical cancer cells were treated with HAND2-AS1 or si-E2F4 RNA, or C16orf74, after which the proliferation, colony formation, migration and invasion were detected. Moreover, the binding between HAND2-AS1 and E2F4 or between E2F4 and C16orf74 was explored. Finally, the tumorigenesis of cervical cancer cells was measured in nude mice with altered HAND2-AS1/E2F4/C16orf74 expression. HAND2-AS1 exhibited poor expression in cervical cancer, and HAND2-AS1 overexpression suppressed the proliferation, colony formation, migration and invasion of cervical cancer cells. In addition, HAND2-AS1 was found to recruit transcription factor E2F4 to C16orf74 promoter region and down-regulate C16orf74 expression. Lastly, HAND2-AS1/E2F4/C16orf74 modulated the tumorigenesis of cervical cancer in nude mice. In conclusion, this study provided evidence on the inhibitory effect of HAND2-AS1 on the development of cervical cancer through the suppression of C16orf74 expression by recruiting transcription factor E2F4. This study highlights the potential of lncRNA HAND2-AS1 as a target in the treatment of cervical cancer.

Abstract
Introduction Long non-coding RNAs (lncRNAs) are regarded as crucial regulators for cancer initiation and progression. Heart and Neural Crest Derivatives Expressed 2 antisense RNA 1 (HAND2-AS1) was recently proposed to function as tumor suppressor in several human cancers. However, its role in gastric cancer (GC) remains unclear. Methods HAND2-AS1 expression in GC tissues and normal tissues was analyzed at GEPIA (a web server for gene expression profiling analysis). Moreover, RT-qPCR method was utilized to explore HAND2-AS1 expression in GC cells and normal cell. In vitro experiments were carried out using cell counting kit-8 assay, colony formation assay, and flow cytometry assay, respectively. Bioinformatic analysis and luciferase activity reporter assay were performed to identify the downstream targets of HAND2-AS1. Results We found HAND2-AS1 has decreased expression in both GC tissues and cells. Overexpression of HAND2-AS1 was able to inhibit GC cell proliferation, colony formation, but promote apoptosis. On the contrary, knockdown of HAND2-AS1 could cause the opposite effects on GC cells. Furthermore, HAND2-AS1 was shown to function as a competitive RNA that binds with microRNA-590-3p (miR-590-3p) to affect the expression of potassium sodium-activated channel subfamily T member 2 (KCNT2). Discussion Our results indicated the tumor suppressive role of HAND2-AS1 in GC. Also, the newly identified HAND2-AS1/miR-590-3p/KCNT2 axis will help us to understand the role of HAND2-AS1 in cancer.

Abstract
Gastric cancer (GC) is one of the most frequently occurring life-threatening malignancies worldwide. Due to its high mortality rate, the discovery of putative biomarkers that may be sensitive and specific to GC is of seminal importance. Long non-coding RNAs (lncRNAs) are non-translatable RNAs whose transcript length exceeds 200 base pairs. The dysregulation of lncRNA expression plays a key role in tumorigenesis and development. In the present study, the expression profiles of lncRNAs, microRNAs and mRNAs of 361 GC tissues (and 32 normal gastric tissues) were downloaded from The Cancer Genome Atlas database. Furthermore, differentially expressed RNAs were analyzed by the DEseq package. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses confirmed some significant dysregulated signaling pathways and target RNAs. As a result, an lncRNA-associated competing endogenous RNA (ceRNA) network was constructed. Kaplan-Meier analysis of the differentially expressed RNAs associated with GC pathogenesis confirmed that the lncRNAs PVT1, HAND2-AS1 and ZNF667-AS1 were potentially associated with the prognosis of GC (P<0.05). The present study suggests the mechanism of ceRNA networks in GC, and further demonstrates that aberrant lncRNA expression may be used as an effective diagnostic tool (or target) for the prognosis of GC.

Abstract
Hepatocellular carcinoma (HCC) is the most prevalent liver cancer, characterized by a high rate of recurrence and heterogeneity. Liver cancer stem cells (CSCs) may well contribute to both of these pathological properties, but the mechanism underlying their self-renewal maintenance is poorly understood. Here, we identified a long noncoding RNA (lncRNA) termed HAND2-AS1 that is highly expressed in liver CSCs. Human HAND2-AS1 and its mouse ortholog lncHand2 display a high level of conservation. HAND2-AS1 is required for the self-renewal maintenance of liver CSCs to initiate HCC development. Mechanistically, HAND2-AS1 recruits the INO80 chromatin-remodeling complex to the promoter of BMPR1A, thereby inducing its expression and leading to the activation of BMP signaling. Importantly, interfering with expression of HAND2-AS1 by antisense oligonucleotides (ASOs) and BMPR1A by siRNAs has synergistic anti-tumorigenic effects on humanized HCC models. Moreover, knockout of lncHand2 or Bmpr1a in mouse hepatocytes impairs BMP signaling and suppresses the initiation of liver cancer. Our findings reveal that HAND2-AS1 promotes the self-renewal of liver CSCs and drives liver oncogenesis, offering a potential new target for HCC therapy.

Abstract
Long noncoding RNAs (lncRNAs) represent a novel type of noncoding RNAs of over 200 nucleotides, characterized by no or limited protein-coding potential. Although the function of lncRNAs attracts increasing attention recently, the relationship between lncRNA and colorectal cancer (CRC) remains further investigation. In our study, we found that lncRNA HAND2-AS1 was markedly downregulated in CRC tissues. And its expression level was negatively correlated with metastasis and advanced stage in CRC patients. Furthermore, we showed that HAND2-AS1 low expression predicted poor prognosis. Functionally, we found that overexpression of HAND2-AS1 obviously attenuated the proliferation and invasion of CRC cells. Ectopic expression of HAND2-AS1 also inhibited tumor propagation in vivo. In mechanism, HAND2-AS1 served as a sponge of miR-1275 which targeted KLF14. Through facilitating KLF14 expression, HAND2-AS1 suppressed CRC progression. In conclusion, our study demonstrated that HAND2-AS1 exerts a suppressive role in CRC by sponging miR-1275 and modulating KLF14 expression.
