Abstract
Glioma is a common life-threatening tumor with high malignancy and high invasiveness. LncRNA ZFPM2 antisense RNA 1 (ZFPM2-AS1) was confirmed to be implicated in numerous tumors, while its biological function and mechanism have not been thoroughly understood in glioma. The gene expression was measured by RT-qPCR. Cell proliferation, cell cycle, and cell apoptosis of glioma cells were validated by CCK-8, colony formation, flow cytometry and TUNEL assays. The effect of ZFPM2-AS1 on tumor growth was verified by in vivo assay. The exploration on ZFPM2-AS1-mediated mechanism was carried out via ChIP, luciferase reporter, and RIP assays. In the present study, ZFPM2-AS1 was demonstrated as a highly-expressed lncRNA in glioma tissues and cells. ZFPM2-AS1 silencing suppressed cell proliferation and cell cycle, but facilitated cell apoptosis. In addition, the inhibitive effect of silenced ZFPM2-AS1 was also observed in tumor growth. Furthermore, we found that SP1 interacted with ZFPM2-AS1 promoter to transcriptionally activate ZFPM2-AS1 expression. Moreover, ZFPM2-AS1 was identified as a competing endogenous RNA (ceRNA) for miR-515-5p to target SOD2. Rescue assays verified that SOD2 overexpression partially abolished the suppressive impact of ZFPM2-AS1 silencing on glioma cell growth. In conclusion, this study corroborated the regulatory mechanism of SP1/ZFPM2-AS1/miR-515-5p/SOD2 axis in glioma, indicating that targeting ZFPM2-AS1 might be an effective way to treat glioma.

Abstract
This research aimed to explore the biological role of long non-coding RNA (lncRNA) ZFAS1 in bupivacaine-induced neurotoxicity. The levels of lncRNA ZFAS1, miR-421, and zinc finger protein 564 (ZNF564) were detected by RT-qPCR. MTT and TUNEL assays were utilized to evaluate cell viability and apoptosis, respectively. Caspase-3 activity was measured by the caspase-3 activity assay kit. The binding ability between miR-421 and ZFAS1 or ZNF564 was confirmed by Rip and dual-luciferase reporter assays. In this study, it was found that the levels of ZFAS1 and ZNF564 were gradually upregulated and miR-421 expression was downregulated with increasing concentrations of bupivacaine. Functional assays indicated that the silencing of ZFAS1 suppressed cell viability and facilitated cell apoptosis of SH-SY5Y cells, while overexpression of ZFAS1 had the opposite effects. Moreover, it was identified that miR-421 was a target of ZFAS1, and ZFAS1 regulated the bupivacaine-induced neurotoxicity via miR-421. In addition, we confirmed that ZNF564 was a downstream target of miR-421. The upregulation of miR-421 decreased the cell viability, and increased the cell apoptosis rate and caspase-3 activity, while the upregulation of ZND564 partially abolished these effects. Finally, it was demonstrated that ZFAS1 could upregulate the expression of ZNF564 by targeting miR-421. In conclusion, our results demonstrated that ZFAS1 alleviated bupivacaine-induced neurotoxicity through the miR-421/ZNF564 axis, suggesting a new strategy for the amelioration of bupivacaine-induced neurotoxicity.

Abstract
Background As lymphatic vessel is a major route for solid tumor metastasis, they are considered an essential part of tumor drainage conduits. Apart from forming the walls of lymphatic vessels, lymphatic endothelial cells (LECs) have been found to play multiple other roles in the tumor microenvironment, calling for a more in-depth review. We hope that this review may help researchers gain a detailed understanding of this fast-developing field and shed some light upon future research. Methods To achieve an informative review of recent advance, we carefully searched the Medline database for English literature that are openly published from the January 1995 to December 2020 and covered the topic of LEC or lymphangiogenesis in tumor progression and therapies. Two different authors independently examined the literature abstracts to exclude possible unqualified ones, and 310 papers with full texts were finally retrieved. Results In this paper, we discussed the structural and molecular basis of tumor-associated LECs, together with their roles in tumor metastasis and drug therapy. We then focused on their impacts on tumor cells, tumor stroma, and anti-tumor immunity, and the molecular and cellular mechanisms involved. Special emphasis on lung cancer and possible therapeutic targets based on LECs were also discussed. Conclusions LECs can play a much more complex role than simply forming conduits for tumor cell dissemination. Therapies targeting tumor-associated lymphatics for lung cancer and other tumors are promising, but more research is needed to clarify the mechanisms involved.

Abstract
Vascular endothelial growth factors (VEGFs) bind to membrane receptors on a wide variety of cells to regulate diverse biological responses. The VEGF-A family member promotes vasculogenesis and angiogenesis, processes which are essential for vascular development and physiology. As angiogenesis can be subverted in many disease states, including tumour development and progression, there is much interest in understanding the mechanistic basis for how VEGF-A regulates cell and tissue function. VEGF-A binds with high affinity to two VEGF receptor tyrosine kinases (VEGFR1, VEGFR2) and with lower affinity to co-receptors called neuropilin-1 and neuropilin-2 (NRP1, NRP2). Here, we use a structural viewpoint to summarise our current knowledge of VEGF-VEGFR activation and signal transduction. As targeting VEGF-VEGFR activation holds much therapeutic promise, we examine the structural basis for anti-angiogenic therapy using small-molecule compounds such as tyrosine kinase inhibitors that block VEGFR activation and downstream signalling. This review provides a rational basis towards reconciling VEGF and VEGFR structure and function in developing new therapeutics for a diverse range of ailments.

Abstract
Long noncoding RNA nuclear paraspeckle assembly transcript 1 (NEAT1) is regarded as an oncogene in multiple cancers. Previous studies have shown that NEAT1 is involved in the proliferation and tumorigenesis of glioma cells, while miR-185-5p functions as a tumor suppressor in glioma. However, the underlying molecular mechanism of NEAT1 in glioma, especially in association with miR-185-5p, has not been studied. In this study, we first demonstrated that NEAT1 expression was upregulated, and miR-185-5p downregulated in glioma tissues and cells. More important, NEAT1 expression was negatively correlated with miR-185-5p expression in glioma tissues. In vitro and in vivo experiments verified that NEAT1 was a competing endogenous RNA for miR-185-5p for promoting DNA methyltransferase 1 (DNMT1) expression and activated mammalian target of rapamycin (mTOR) signaling, thus inhibiting apoptosis, and promoting glioma migration, proliferation, and epithelial-mesenchymal transition process. Furthermore, NEAT1 knockdown suppressed tumor growth and reduced the expression of proliferation antigen Ki-67, DNMT1, and mTOR, but upregulated the expression of miR-185-5p in vivo. Finally, with mTOR inhibitor rapamycin, we confirmed that NEAT1 promoted glioma activity through mTOR signaling both in vitro and in vivo. In conclusion, these results suggest that NEAT1 promotes glioma tumorigenesis via miR-185-5p/DNMT1/mTOR signaling, which may provide a new target for the diagnosis and therapy of glioma.

Abstract
This paper reviews current treatments for renal cell carcinoma/cancer (RCC) with the multikinase inhibitors (MKIs) sorafenib, sunitinib, lenvatinib and axitinib. Furthermore, it compares these drugs regarding progression-free survival, overall survival and adverse effects (AE), with a focus on hypertension. Sorafenib and sunitinib, which are included in international clinical guidelines as first- and second-line therapy in metastatic RCC, are now being challenged by new-generation drugs like lenvatinib and axitinib. These drugs have shown significant clinical benefits for patients with RCC, but all four induce a variety of AEs. Hypertension is one of the most common AEs related to MKI treatment. Comparing sorafenib, sunitinib and lenvatinib revealed that sorafenib and sunitinib had the same efficacy, but sorafenib was safer to use. Lenvatinib showed better efficacy than sorafenib but worse safety. No trials have yet been completed that compare lenvatinib with sunitinib. Although axitinib promotes slightly higher hypertension rates compared to sunitinib, the overall discontinuation rate and cardiovascular complications are favourable. Although the mean rate of patients who develop hypertension is similar for each drug, some trials have shown large differences, which could indicate that lifestyle and/or genetic factors play an additional role.

Abstract
FGF19 is a noncanonical FGF ligand that can control a broad spectrum of physiological responses, which include bile acid homeostasis, liver metabolism and glucose uptake. Many of these responses are mediated by FGF19 binding to its FGFR4/β-klotho receptor complex and controlling activation of an array of intracellular signaling events. Overactivation of the FGF19/FGFR4 axis has been implicated in tumorigenic formation, progression and metastasis, and inhibitors of this axis have recently been developed for single agent use or in combination with other anticancer drugs. Considering the critical role of this receptor complex in cancer, this review focuses on recent developments and applications of FGF19/FGFR4-targeted therapeutics.

Abstract
INTRODUCTION: Renal cell carcinoma represents a neoplasm with usually aggressive behavior. Due to its nature, it is often diagnosed in an advanced stage or when metastatic dissemination has been occurred. The aim of this review is to provide an overview of the current management of metastatic renal cell carcinoma and briefly discuss the potential new therapeutic strategies for this disease. METHODS: Review of the literature was performed in PubMed/MEDLINE, Cochrane, and EMBASE and we included English articles up to February 2018. RESULTS: Over the past years, many efforts have been made in the context of confronting metastatic disease and led to the introduction of targeted therapies. More available agent options, including various tyrosine kinase inhibitors and mammalian target of rapamycin inhibitors, can be served nowadays as the first-, second-, and third-line therapy in the metastatic setting of the disease providing better outcomes. DISCUSSION: Moreover, regarding the recent advances in the field of cancer immunotherapy, the landscape of metastatic renal cell carcinoma management is being shaped toward novel immunotherapeutic interventions alone or in combination with other types of therapy.

Abstract
Multikinase inhibitors (MKI) and mammalian target of rapamycin (mTOR) inhibitors prolong progression-free (PFS) and overall survival (OS) in the treatment of metastatic renal cell carcinoma (mRCC) by reducing angiogenesis and tumor growth. In this regard, the MKI lenvatinib and the mTOR inhibitor everolimus proved effective when applied alone, but more effective when they were administered combined. Recently, both drugs were included in clinical trials, resulting in international clinical guidelines for the treatment of mRCC. In May 2016, lenvatinib was approved by the American Food and Drug Administration (FDA) for the use in combination with everolimus, as treatment of advanced renal cell carcinoma following one prior antiangiogenic therapy. A major problem of treating mRCC with lenvatinib and everolimus is the serious adverse event (AE) of arterial hypertension. During the treatment with everolimus and lenvatinib combined, 42% of the patients developed hypertension, while 10% of the patients treated with everolimus alone and 48% of the of the lenvatinib only treated patients developed hypertension. Lenvatinib carries warnings and precautions for hypertension, cardiac failure, and other adverse events. Therefore, careful monitoring of the patients is necessary.

Abstract
Inter- and intra-tumour molecular heterogeneity is increasingly recognized in clear cell renal cell carcinoma (ccRCC). It may partially explain the diversity of responses to targeted therapies and the various clinical outcomes. In this study, a 56-year-old male ccRCC patient with multiple metastases received radical nephrectomy and resection of the metastatic tumour in chest wall. The surgical specimens were implanted into nude mice to establish patient-derived xenograft (PDX) models with KI2367 model derived from the primary tumour and KI2368 model from the metastastic tumour. The two modles were treated with Sorafenib, Sunitinib, Axitinib, combined Sorafenib/Sunitinib, or alternating therapy of Sorafenib and Sunitinib. Significant anti-tumour activity was found in KI2367 treated with Sorafenib/Sunitinib monotherapy, combined Sorafenib/Sunitinib, and alternating therapy of Sorafenib/Sunitinib (P<0.05) but not in that treated with Axitinib monotherapy. In contrast, KI2368 was significantly responsive to Sunitinib monotherapy, combined Sorafenib/Sunitinib therapy and alternating therapy of Sorafenib/Sunitinib but not responsive to Sorafenib and Axitinib monotherapy (P<0.05). RNAseq of the two models demonstrated that the expression levels of 1,725 genes including the drug targeted genes of PDGFA, PDGFB and PDGFRA were >5-fold higher in KI2367 than in KI2368 and the expression levels of 994 genes were > 5-fold higher in KI2368 than in KI2367. These results suggest the presence of intra-tumour molecular heterogeneity in this patient. This heterogeneity may influence the response to targeted therapies. Multiple biopsy, liquid biopsy and genomic analysis of intra- tumour molecular heterogeneity may help guide a more precise and effective plan in selecting targeted therapies for ccRCC patients.

Hong Q, Li O, Zheng W, Xiao WZ, Zhang L, Wu D, Cai GY, He JC, Chen XM. LncRNA HOTAIR regulates HIF-1α/AXL signaling through inhibition of miR-217 in renal cell carcinoma. Cell Death Dis 2017; 8:e2772. [PMID: 28492542 PMCID: PMC5520706 DOI: 10.1038/cddis.2017.181] [Citation(s) in RCA: 130] [Impact Index Per Article: 18.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2017] [Revised: 03/16/2017] [Accepted: 03/17/2017] [Indexed: 02/07/2023]
Abstract
Long non-coding RNA HOTAIR was regarded as an oncogene in multiple cancers. Previous studies have shown that HOTAIR is involved in the proliferation and tumorigenesis of renal carcinoma cells, while microRNA (miR)-217 functions as a tumor suppressor in renal cell carcinoma (Rcc). However, the underlying molecular mechanism of HOTAIR in Rcc, especially in association with miR-217, has not been studied. In this study, we first demonstrated that HOTAIR expression was upregulated, which was correlated with tumor progression, and miR-217 downregulated in Rcc tissues and cells. Importantly, HOTAIR expression was negatively correlated with miR-217 expression in Rcc tissues. Gain- and loss-of-function of HOTAIR revealed that HOTAIR functioned as a ceRNA for miR-217 to facilitate HIF-1α expression and then upregulated AXL level promoting Rcc proliferation, migration, and EMT process, and inhibiting apoptosis. Furthermore, HOTAIR knockdown suppressed tumor growth and reduced the expression of proliferation antigen ki-67, HIF-1α, and AXL, but upregulated the expression of miR-217 in vivo. Finally, with AXL inhibitor BGB324, we confirmed that HOTAIR promoted Rcc activity through AXL signaling both in vitro and in vivo. In conclusion, these results suggest that HOTAIR promotes Rcc tumorigenesis via miR-217/HIF-1α/AXL signaling, which may provide a new target for the diagnosis and therapy of Rcc disease.
