Abstract
Glioblastoma (GBM) is the most common primary intracranial tumor in the central nervous system, and resistance to temozolomide is an important reason for the failure of GBM treatment. We screened out that Solute Carrier Family 2 Member 10 (SLC2A10) is significantly highly expressed in GBM with a poor prognosis, which is also enriched in the NF-E2 p45-related factor 2 (NRF2) signalling pathway. The NRF2 signalling pathway is an important defence mechanism against ferroptosis. SLC2A10 related LINC02381 is highly expressed in GBM, which is localized in the cytoplasm/exosomes, and LINC02381 encoded micropeptides are localized in the exosomes. The micropeptide encoded by LINC02381 may be a potential treatment strategy for GBM, but the underlying mechanism of its function is not precise yet. We put forward the hypothesis: “The micropeptide encoded by LINC02381 regulates ferroptosis through the glucose transporter SLC2A10 in GBM.” This study innovatively used machine learning for micropeptide to provide personalized diagnosis and treatment plans for precise treatment of GBM, thereby promoting the development of translational medicine. The study aimed to help find new disease diagnoses and prognostic biomarkers and provide a new strategy for experimental scientists to design the downstream validation experiments.

Abstract
PURPOSE LncRNAs play essential roles in the cellular and molecular biology of glioma. Some LncRNAs exert their role through sponging miRNAs and regulating multiple signaling pathways. LINC02381 is involved in several cancer types as either oncogene or tumor suppressor. Here, we intended to find the molecular mechanisms of the LINC02381 effect during the glioma progression in related cell lines. METHODS AND RESULTS RNA-seq data analysis indicated the oncogenic characteristics of LINC02381, and RT-qPCR results confirmed its upregulation compared to normal tissues. Besides its expression was relatively stronger in invasive glioma cell lines. Furthermore, in silico analysis revealed LINC02381 is concentrated in the cytoplasm and predicted its sponging effect against miR-128 and miR-150, which was verified through dual luciferase assay. When LINC02381 was overexpressed in 1321N1, U87, and A172 cell lines, IGF1R and TrkC receptors as well as their downstream pathways (PI3K and RAS/MAPK), were upregulated, detected by RT-qPCR, and verified by western analysis. Consistently, LINC02381 overexpression was followed by an increased proliferation rate of transfected glioma cell lines, detected by flow cytometry and MTT assay, and RT-qPCR. It also resulted in elevated EMT and stemness markers expression level, increased migration rate, and reduced apoptosis rate, detected by RT-qPCR, western analysis, scratch test, and Annexin/PI flow cytometry analysis, respectively. CONCLUSION The overall results indicated that LINC02381 exerts its oncogenic effect in glioma cells through sponging miR-128 and miR-150 to upregulate the IGF1R signaling pathway. Our results introduce LINC02381 and miR-128, and miR-150 as potential prognosis and therapy targets for the treatment of glioma.

Abstract
INTRODUCTION Human umbilical cord blood-derived MSCs (hUC-MSCs) have the potential to differentiate into osteoblasts. This study investigated the function and potential mechanisms of a novel lncRNA LINC02381 in hUC-MSC osteogenic differentiation. MATERIALS AND METHODS hUC-MSCs were maintained in osteogenic differentiation medium. RT-qPCR assay was performed to assess LINC02381 expression. Alizarin Red S (ARS) and alkaline phosphatase (ALP) staining were performed to evaluate osteogenic differentiation. The interaction between miR-21 and LINC0238/KLF12 was determined by luciferase reporter and RNA immunoprecipitation (RIP) assays. Chromatin immunoprecipitation (ChIP) assay was used to confirm the transcriptional regulation of KLF12 on Wnt4 promoter. The nuclear translocation of β-catenin was evaluated using immunofluorescence. hUC-MSCs seeded on Bio-Oss Collagen scaffolds were transplanted into nude mice to assess in vivo osteogenesis. Bone formation was observed by H&E and Masson's trichrome staining. OSX and OPN levels were assessed by immunohistochemistry. RESULTS LINC02381 was up-regulated in the clinical samples of osteoporotic patients. However, LINC02381 expression was reduced during osteogenic differentiation of hUC-MSCs. Enforced expression of LINC02381 suppressed the osteogenic differentiation of hUC-MSCs. Mechanistically, LINC02381 sponged miR-21 to enhance KLF12 expression, which led to the inactivation of Wnt/β-catenin signaling pathway. Furthermore, miR-21 mimics or KLF12 silencing counteracted LINC02381-induced inhibition of osteogenic differentiation, whereas IWP-4 (an inhibitor of Wnt pathway) abolished this effect. CONCLUSION In summary, LINC02381 repressed osteogenic differentiation of hUS-MSCs through sponging miR-21 to enhance KLF12-mediated inactivation of Wnt/β-catenin pathway, indicating that LINC02381 might be a therapeutic target for osteoporosis.

Abstract
Emerging investigations have demonstrated that lncRNAs are key crucial modulators in cancer. In this study, we investigated the role of LINC02381 in breast cancer (BC). Reverse transcriptase quantitative polymerase chain reaction measured the LINC02381 level in BC tissues and cells. Colony formation, EdU staining, wound healing and Transwell experiments examined the impact of LINC02381 depletion on BC cell phenotypes. Relationship among miR-1271-5p, LINC02381, and FN1 was tested through applying RIP, luciferase reporter, and RNA pull-down assays. We found that LINC02381 expression was elevated in BC. Functionally, LINC02381 knockdown hampered BC cell proliferation, migration, and invasion. LINC02381 overexpression accelerated tumor formation in vivo. Mechanistically, LINC02381 acted as a ceRNA to increase FN1 via decoying miR-1271-5p. Additionally, LINC02381 activated PI3K/AKT pathway by upregulating FN1. Rescue assays indicated that FN1 upregulation or PI3K/AKT activation rescued the LINC02381 knockdown-mediated inhibition on malignant phenotypes of BC cells. Overall, LINC02381 exerts carcinogenic effects in BC by the miR-1271-5p/FN1 axis to activate PI3K/AKT pathway.

Abstract
Glioma, featured with high incidence and low survival rate, is the most common type of primary brain tumor, severely affecting human life worldwide. LINC02381 is an interesting lncRNA functioning as oncogenic lncRNA in some cancers but as tumor-suppressor in others, but no report demonstrates its association with and function in glioma. Intriguingly, we found in a bioinformatics website LncRNADisease that LINC02381 was closely related to malignant glioma, so this study aimed to figure out the expression and function of LINC02381 in glioma. By RT-qPCR, we confirmed LINC02381 upregulation in glioma cells. Functional experiments demonstrated that LINC02381 knockdown repressed glioma cell proliferation and induced apoptosis. Boinformatics tools and RT-qPCR revealed the positive correlation between LINC02381 and CBX5 in glioma cells. More importantly, we confirmed that LINC02381 could interact and work synergistically with CEBPβ to bind to CBX5 promoter and activate CBX5 transcriptionally. Additionally, rescue experiments indicated that CBX5 up-regulation reversed the decline in cell proliferation and the augment in cell apoptosis caused by LINC02381 knockdown. To conclude, LINC02381 could facilitate CBX5 transcription via interaction with CEBPβ, thus exerting its oncogenic role in glioma cells, which could contribute to better understanding of glioma.

Abstract
Breast cancer is a common neoplasm among women. This type of cancer is among malignancies in which role of long non-coding RNAs (lncRNAs) has been extensively explored. Some recently recognized lncRNAs have been less investigated in this neoplastic condition. LncRNAs that regulate tumor immunity are among those contributing in the pathogenesis of cancer. In the present expression assay, we compared expressions of nine immune-related lncRNAs namely lnc-MICAL3-2 (AC016027.1), lnc-DDX31 (AL445645.1), LINC01063, LINC02381, ENST0000615051 (AC083809.1), AC009237.14 (lnc-TRIM43B-1), ENST0000603791, LINC1234 and AC008760.1 between breast cancer samples and their paired non-cancerous samples. Expression levels of lnc-MICAL3-2, lnc-DDX31, LINC01063, LINC02381, ENST0000615051 and lnc-TRIM43B-1 were significantly decreased in breast cancer samples compared with paired control tissues (Posterior mean difference= -2.774, -2.012, -2.012, -2.015, -0.884 and -2.872; P values= 0.019, 0.0001, 0.0001, 0.0001, 0.032 and 0.0001, respectively). Expression levels of these lncRNAs have been associated with a number of clinical characteristics of breast cancer patients. Lnc-TRIM43B-1 had the highest performance in distinguishing between tumoral and non-tumoral tissues (AUC=0.82, Sensitivity=76%, Specificity=73.24%). As these lncRNAs could differentiate tumor samples from control samples, they might be regarded as putative tissue markers for breast cancer.

Abstract
Background It has been proved that lncRNAs could function as CeRNA for miRNAs in tumor growth and metastasis for cervical cancer. This paper aims to identify the role of LINC02381 in cervical cancer cells. Materials and Methods RT-qPCR was utilized to measure the expression levels of LINC02381 in cervical cancer tissues and cells. MTT, colony formation assay, transwell assay, RT-qPCR, and Western blotting were performed to investigate the roles of LINC02381 in cervical cancer cells. RegRNA 2.0 was used to predict the miRNA-binding sites of LINC02381. Luciferase reporter assay and RT-qPCR were employed to confirm the sponging effect between miR-133b and LINC02381. Results This study showed that LINC02381 was up-regulated in cervical cancer cells and acted as an oncogene in the development of cervical cancer. LINC02381 promoted cell viability and metastasis via sponging miR-133b. Moreover, miR-133b could target its downstream mediator of RhoA and inhibit its expression. Conclusion Overall, our results indicated that LINC02381 functions as an oncogene in cervical cancer and could serve as a novel target for cervical cancer therapies in the future.
