Abstract
HOXC cluster antisense RNA 3 (HOXC-AS3) is a novel long noncoding RNA (lncRNA) that exhibits aberrant expression patterns in various cancer types. Its expression is closely related to clinicopathological features, demonstrating significant clinical relevance across multiple tumors. And HOXC-AS3 plays multifaceted roles in tumor progression, impacting cell proliferation, apoptosis, migration, invasion, epithelial-mesenchymal transition (EMT), autophagy, senescence, tumor growth, and metastasis. In this review, we summarized and comprehensively analyzed the expression and clinical significance of HOXC-AS3 as a diagnostic and prognostic biomarker for malignancies. Additionally, we presented an in-depth update on HOXC-AS3's functions and regulatory mechanisms in cancer pathogenesis. This narrative review underscores the importance of HOXC-AS3 as a promising lncRNA candidate in cancer research and its potential as a predictive biomarker and therapeutic target in clinical applications.

SETD1A-mediated H3K4me3 methylation upregulates lncRNA HOXC-AS3 and the binding of HOXC-AS3 to EP300 and increases EP300 stability to suppress the ferroptosis of NSCLC cells. Thorac Cancer 2023; 14:2579-2590. [PMID: 37548102 PMCID: PMC10481147 DOI: 10.1111/1759-7714.15037] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 06/26/2023] [Accepted: 06/27/2023] [Indexed: 08/08/2023] Open
Abstract
BACKGROUND Histone methyltransferases are crucial regulators in non-small cell lung cancer (NSCLC) development. This study explored the mechanism of histone methyltransferase SET domain containing 1A (SETD1A)-mediated H3K4me2 methylation in NSCLC cell ferroptosis and provides novel targets for NSCLC treatment. METHODS Upon downregulation of SETD1A in NSCLC cell lines, cell proliferation potential, malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) activities, iron content, and SETD1A, long noncoding RNA HOXC cluster antisense RNA 3 (lncRNA HOXC-AS3), E1A binding protein p300 (EP300), glutathione peroxidase 4 (GPX4) expressions were determined via cell counting kit-8, ELISA, iron assay kits, RT-qPCR, and western blot. Enrichment levels of SETD1A and H3K4me3 in the HOXC-AS3 promotor were measured via chromatin immunoprecipitation, and the binding of HOXC-AS3 and EP300 was analyzed via RNA immunoprecipitation. Rescue experiments were performed to confirm their roles in NSCLC cell ferroptosis. Xenograft tumor models were established to validate the role of SETD1A in vivo. RESULTS SETD1A, H3K4me3, HOXC-AS3, and EP300 were highly-expressed in NSCLC cells. Silencing SETD1A inhibited NSCLC cell proliferation, increased MDA and iron levels, and decreased SOD, GSH, and GPX4 levels. SETD1A downregulation reduced H3K4me3 level, HOXC-AS3 expression, the binding of HOXC-AS3 to EP300, and EP300 stability. Overexpression of HOXC-AS3 or EP300 reversed the promotion of silencing SETD1A on NSCLC cell ferroptosis. Silencing SETD1A reduced tumor volume and weight and positive rate of ki67 and increased ferroptosis through the HOXC-AS3/EP300 axis. CONCLUSION SETD1A-mediated H3K4me2 methylation promoted HOXC-AS3 expression, binding of HOXC-AS3 to EP300, and EP300 stability, thereby suppressing NSCLC cell ferroptosis.

Abstract
NSCLC is common and is the primary cause of cancer-related deaths due to a lack of early diagnosis and its propensity for metastasis. The pathogenesis of NSCLC is still unclear. Here, we explored the molecular mechanisms underlying NSCLC development, focusing on the HOXC-AS3/YBX1/HOXC8 axis. Human NSCLC specimens and cell lines were used. qRT-PCR and western blotting were utilised to examine the levels of HOXC-AS3/YBX1/HOXC8. CCK-8, colony formation, scratch wound healing and Transwell assays were performed to evaluate cancer cell proliferation, migration and invasion. A nude mouse xenograft model was used to examine tumour growth and metastasis in vivo. RNA pull-down, chromatin immunoprecipitation, coimmunoprecipitation and dual-luciferase assays were applied to validate the interactions of HOXC-AS3/YBX1, MDM2/YBX1 and the YBX1/HOXC8 promoter. The levels of HOXC-AS3 and HOXC8 were increased in human NSCLC specimens and cells. Knockdown of HOXC-AS3 suppressed NSCLC cell proliferation, migration and invasion, as well as tumour growth and metastasis in vivo. HOXC-AS3 directly bound to YBX1 to suppress its ubiquitination mediated by MDM2. YBX1 bound to the HOXC8 promoter and enhanced its transcription. Knockdown of HOXC8 inhibited the effects of HOXC-AS3 overexpression on NSCLC. HOXC-AS3 promotes NSCLC growth and metastasis by stabilising YBX1 and thus increasing HOXC8 transcription. Our study indicates that the HOXC-AS3/YBX1/HOXC8 axis could serve as a biomarker for NSCLC diagnosis or as a target for therapy development.

Abstract
HOXC cluster antisense RNA 3 (HOXC-AS3) is a long noncoding RNA (lncRNA) that plays a crucial role in various tumors; nevertheless, its role in glioma and its mechanism have not been completely elucidated. In this research, we discovered that HOXC-AS3 was over-expression in glioma cells and tissues and was associated with prognosis. Next, we determined that HOXC-AS3 targeted miR-216 as a sponge and that the F11 receptor (F11R) was the target of miR-216 by online databases analysis, qRT–PCR, and luciferase reporter assay. In addition, the rescue experiments confirmed that HOXC-AS3 regulated the expression of F11R by competitively binding miR-216 and functioning as a competing endogenous RNA (ceRNA). The intracranial glioblastoma mouse model suggested that HOXC-AS3 could promote glioma malignant progression in vivo. In summary, our study shows that the HOXC-AS3/miR-216/F11R axis plays an important role in the malignant progression of glioma, and may provide new ideas for the treatment of glioma.

Abstract
OBJECTIVE Long non-coding RNA (lncRNA) HOXC-AS3 has been characterized as a cancer-related lncRNA in many types of cancer, while its role in colorectal cancer (CRC) is unknown. METHODS The expression of HOXC-AS3 and TGF-β2 were detected by RT-qPCR. Overexpression assays were performed to explore the interaction between HOXC-AS3 and TGF-β2. A follow-up study was performed to explore the prognostic value of HOXC-AS3 for CRC. The direct interaction between HOXC-AS3 and miR-1269 was assessed with RNA-RNA pulldown assay. Transwell assays were performed to determine the role of HOXC-AS3 and TGF-β2 in regulating CRC cell invasion and migration. RESULTS HOXC-AS3 was significantly downregulated in CRC tissues, while TGF-β2 was significantly upregulated in CRC tissues compared to that in adjacent non-cancer tissues of CRC patients. The follow-up study showed that low expression levels of HOXC-AS3 in CRC tissues were closely correlated with poor survival. Correlation analysis showed that HOXC-AS3 and TGF-β2 were inversely correlated across CRC tissues but not non-cancer tissues. Overexpression of HOXC-AS3 in the two cell lines resulted in downregulation of TGF-β2, while the expression of HOXC-AS3 was not affected by TGF-β2. Transwell migration and invasion assay showed that overexpression of TGF-β2 increased cell invasion and migration, while overexpression of HOXC-AS3 decreased cell migration and invasion. In addition, overexpression of HOXC-AS3 attenuated the effects of overexpression of TGF-β2. MiR-1269 increased the expression of TGF-β2. HOXC-AS3 directly interacted with miR-1269 in CRC cells. CONCLUSIONS Upregulation of HOXC-AS3 inhibited TGF-β2-induced colorectal cancer (CRC) cell migration and invasion possibly by sponging miR-1269.

Abstract
Emerging evidence reveals that long noncoding RNAs (lncRNAs) contribute to human tumorigenesis. Nevertheless, the function of HOXC cluster antisense RNA 3 (HOXC-AS3) in human cervical cancer (CC) remains largely unknown. The levels of HOXC-AS3, miR-105-5p and SOS1 in CC tissues and cells were monitored by reverse transcription-polymerase chain reaction (RT-PCR) and western blot (WB). Gain- and loss-of-function experiments were conducted to verify the function of HOXC-AS3 and miR-105-5p in CC cells. Meanwhile, cell proliferation, apoptosis, migration and invasion were examined by the cell counting kit-8 (CCK8) experiment, colony formation assay, flow cytometry and Transwell assay. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were carried out to test the regulatory interaction of HOXC-AS3, miR-105-5p and SOS1. In addition, in vivo experiment was performed to certain the role of HOXC-AS3 in tumorigenesis of CC. HOXC-AS3 was overexpressed in CC tissues (vs. adjacent normal tissues) and CC cells. Besides, the higher HOXC-AS3 profile was associated with the poorer clinical prognosis of CC patients. Overexpression of HOXC-AS3 promoted cell growth, migration and invasion, hampered apoptosis, whereas knocking down HOXC-AS3 exhibited the reverse effects. MiR-105-5p was a downstream target of HOXC-AS3, and it mediated the HOXC-AS3-induced oncogenic effects. Mechanistically, the bioinformatic analysis illustrated that SOS1 was targeted by miR-105-5p. Up-regulating SOS1 heightened the growth, migration and invasion of CC cells by enhancing the ErbB signaling pathway, which was reversed by miR-105-5p. Up-regulated HOXC-AS3 aggravates CC by promoting SOS1 expression via targeting miR-105-5p.

Abstract
Bilaterian animals operate the clusters of Hox genes through a rich repertoire of diverse mechanisms. In this review, we will summarize and analyze the accumulated data concerning long non-coding RNAs (lncRNAs) that are transcribed from sense (coding) DNA strands of Hox clusters. It was shown that antisense regulatory RNAs control the work of Hox genes in cis and trans, participate in the establishment and maintenance of the epigenetic code of Hox loci, and can even serve as a source of regulatory peptides that switch cellular energetic metabolism. Moreover, these molecules can be considered as a force that consolidates the cluster into a single whole. We will discuss the examples of antisense transcription of Hox genes in well-studied systems (cell cultures, morphogenesis of vertebrates) and bear upon some interesting examples of antisense Hox RNAs in non-model Protostomia.

Abstract
HOXC-AS3 has been reported to be an oncogenic lncRNA in several types of cancer, while its role in ovarian cancer (OC) is unknown. This study aimed to explore the involvement of HOXC-AS3 in OC. The expression levels of HOXC-AS3, mature miR-96, and miR-96 precursor (premature miR-96) in OC and paired non-tumor tissues from 62 OC patients were determined by RT-qPCR. Correlations were analyzed by linear regression. The expression levels of mature miR-96 and miR-96 precursor in OC cells with the overexpression of HOXC-AS3 were determined by RT-qPCR. The roles of HOXC-AS3 and mature miR-96 in regulating the proliferation of OC cells were explored by CCK-8 assay. HOXC-AS3 was upregulated in OC, while mature miR-96 and miR-96 precursor were downregulated in OC. In OC tissues, HOXC-AS3 was inversely correlated with mature miR-96, but not miR-96 precursor. In OC cells, overexpression of HOXC-AS3 reduced the expression levels of mature miR-96, but not miR-96 precursor. Cell proliferation analysis showed that overexpression of HOXC-AS3 resulted in increased cell proliferation, while overexpression of miR-96 suppressed cell proliferation. In addition, overexpression of HOXC-AS3 attenuated the effects of overexpression of miR-96. HOXC-AS3 suppresses the formation of mature miR-96 in OC cells to promote cell proliferation.
