Shi Y, Yin L, Hao Y, Wang J, Zhou W. KIF2A correlates with lymphovascular invasion and higher tumor stage, and can be used to predict worse prognosis in patients with endometrial carcinoma. Oncol Lett 2024; 28:396.

Abstract
Kinesin family protein 2A (KIF2A) is a microtubule depolymerase that participates in the progression of various cancers; however, its clinical utility in endometrial carcinoma (EC) remains unclear. The aim of the present study was to assess KIF2A expression and its relationship with prognosis in patients with EC. Data from 230 patients with EC who underwent tumor resection were reviewed in the current, retrospective study. KIF2A expression was measured in 230 formalin-fixed paraffin-embedded (FFPE) specimens of tumor tissue and 50 FFPE specimens of non-tumor tissue using immunohistochemistry (IHC). KIF2A expression was elevated in EC tumor tissue vs. non-tumor tissue (P<0.001). Furthermore, tumor KIF2A expression was linked with lymphovascular invasion (P=0.004) and higher International Federation of Gynecology and Obstetrics (FIGO) stage (P=0.001). High tumor KIF2A expression (IHC score>3) was correlated with shorter disease-free survival (DFS; P=0.014) and overall survival (OS; P=0.012). Moreover, the time-dependent receiver operating characteristic curves revealed that tumor KIF2A expression had an acceptable use for estimating the relapse and death risks at each timepoint within 6 years, with each area under the curve remaining stable at ≥0.7. Notably, tumor KIF2A expression (high vs. low) independently forecast shorter DFS (hazard ratio, 2.506; P=0.013), but not OS (P>0.05). Furthermore, information from The Human Protein Atlas database indicated that high tumor KIF2A expression was associated with worse OS in patients with EC (P=0.027). Tumor KIF2A is not only associated with lymphovascular invasion and higher FIGO stage, but also reflects unfavorable survival in patients with EC.

Abstract
Early detection of cancer can significantly improve patient outcomes; however, sensitive and highly specific biomarkers for cancer detection are currently missing. Nullomers are the shortest sequences that are absent from the human genome but can emerge due to somatic mutations in cancer. We examine over 10,000 whole exome sequencing matched tumor-normal samples to characterize nullomer emergence across exonic regions of the genome. We also identify nullomer emerging mutational hotspots within tumor genes. Finally, we provide evidence for the identification of nullomers in cell-free RNA from peripheral blood samples, enabling detection of multiple tumor types. We show multiple tumor classification models with an AUC greater than 0.9, including a hepatocellular carcinoma classifier with an AUC greater than 0.99.

Int J Biol Macromol 2024; 270:132347. [PMID: 38754673 DOI: 10.1016/j.ijbiomac.2024.132347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 05/06/2024] [Accepted: 05/11/2024] [Indexed: 05/18/2024]
Abstract
Aberrant cell proliferation is one of the main characteristics of tumor cells that can be affected by many cellular processes and signaling pathways. Kinesin superfamily proteins (KIFs) are motor proteins that are involved in cytoplasmic transportations and chromosomal segregation during cell proliferation. Therefore, regulation of the KIF functions as vital factors in chromosomal stability is necessary to maintain normal cellular homeostasis and proliferation. KIF deregulations have been reported in various cancers. MicroRNAs (miRNAs) and signaling pathways are important regulators of KIF proteins. MiRNAs have key roles in regulation of the cell proliferation, migration, and apoptosis. In the present review, we discussed the role of miRNAs in tumor biology through the regulation of KIF proteins. It has been shown that miRNAs have mainly a tumor suppressor function via the KIF targeting. This review can be an effective step to introduce the miRNAs/KIFs axis as a probable therapeutic target in tumor cells.

Huang LM, Zhang MJ. Kinesin 26B modulates M2 polarization of macrophage by activating cancer-associated fibroblasts to aggravate gastric cancer occurrence and metastasis. World J Gastroenterol 2024; 30:2689-2708. [PMID: 38855156 PMCID: PMC11154681 DOI: 10.3748/wjg.v30.i20.2689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/28/2024] [Accepted: 04/19/2024] [Indexed: 05/27/2024] Open
Abstract
BACKGROUND The regulatory effects of KIF26B on gastric cancer (GC) have been confirmed, but the specific mechanism still needs further exploration. Pan-cancer analysis shows that the KIF26B expression is highly related to immune infiltration of cancer-associated fibroblasts (CAFs), and CAFs promote macrophage M2 polarization and affect cancers' progression. AIM To investigate the regulatory functions of KIF26B on immune and metastasis of GC. METHODS We analyzed genes' mRNA levels by quantitative real-time polymerase chain reaction. Expression levels of target proteins were detected by immunohistochemistry, ELISA, and Western blotting. We injected AGS cells into nude mice for the establishment of a xenograft tumor model and observed the occurrence and metastasis of GC. The degree of inflammatory infiltration in pulmonary nodes was observed through hematoxylin-eosin staining. Transwell and wound healing assays were performed for the evaluation of cell invasion and migration ability. Tube formation assay was used for detecting angiogenesis. M2-polarized macrophages were estimated by immunofluorescence and flow cytometry. RESULTS KIF26B was significantly overexpressed in cells and tissues of GC, and the higher expression of KIF26B was related to GC metastasis and prognosis. According to in vivo experiments, KIF26B promoted tumor formation and metastasis of GC. KIF26B expression was positively associated with CAFs' degree of infiltration. Moreover, CAFs could regulate M2-type polarization of macrophages, affecting GC cells' migration, angiogenesis, invasion, and epithelial-mesenchymal transition process. CONCLUSION KIF26B regulated M2 polarization of macrophage through activating CAFs, regulating the occurrence and metastasis of GC.

Characterization of Infiltrating Immune Cells and Secretory or Membrane-Associated Proteins in KRAS Lung Adenocarcinoma. J Immunol Res 2023; 2023:4987832. [PMID: 36793588 PMCID: PMC9925262 DOI: 10.1155/2023/4987832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 10/31/2022] [Accepted: 01/16/2023] [Indexed: 02/09/2023] Open
Abstract
Background This study identified the expression and prognosis significance of secretory or membrane-associated proteins in KRAS lung adenocarcinoma (LUAD) and depicted the characteristics between the immune cell infiltration and the expression of these genes. Methods Gene expression data of LUAD samples (n = 563) were accessed from The Cancer Genome Atlas (TCGA). The expression of secretory or membrane-associated proteins was compared among the KRAS-mutant, wild-type, and normal groups, as well as the subgroup of the KRAS-mutant group. We identified the survival-related differentially expressed secretory or membrane-associated proteins and conducted the functional enrichment analysis. Then, the characterization and association between their expression and the 24 immune cell subsets were investigated. We also constructed a scoring model to predict KRAS mutation by LASSO and logistic regression analysis. Results Secretory or membrane-associated genes with differential expression (n = 74) across three groups (137 KRAS LUAD, 368 wild-type LUAD, and 58 normal groups) were identified, and the results of GO and KEGG indicated that they were strongly associated with immune cell infiltrations. Among them, ten genes were significantly related to the survival of patients with KRAS LUAD. The expression of IL37, KIF2, INSR, and AQP3 had the most significant correlations with immune cell infiltration. In addition, eight DEGs from the KRAS subgroups were highly correlated with immune infiltrations, especially TNFSF13B. Using LASSO-logistic regression, a KRAS mutation prediction model based on the 74 differentially expressed secretory or membrane-associated genes was built, and the accuracy was 0.79. Conclusion The research investigated the relationship between the expression of KRAS-related secretory or membrane-associated proteins in LUAD patients with prognostic prediction and immune infiltration characterization. Our study demonstrated that secretory or membrane-associated genes were closely associated with the survival of KRAS LUAD patients and were strongly correlated to immune cell infiltration.

Abstract
Background Kinesin family member 2A (KIF2A) is reported as an oncogene and a potential biomarker for progression and prognosis in several cancers such as cervical, ovarian, and gastric. However, its clinical value in basal-like breast cancer (BLBC) is unclear. This study aims to evaluate KIF2A expression and its correlation with clinical features and survival rates in BLBC patients. Methods KIF2A mRNA and protein expressions in tumor and adjacent tissues from 89 BLBC patients are assessed by reverse transcription-quantitative polymerase chain reaction and immunohistochemistry assays, respectively. Results Both KIF2A protein (p < 0.001) and mRNA expressions (p < 0.001) were higher in tumor than in adjacent tissue. Besides, tumor KIF2A protein expression was positively correlated with N (p = 0.028) and TNM (p = 0.014) stages; meanwhile, tumor KIF2A mRNA expression was positively correlated with N stage (p = 0.046), TNM stage (p = 0.006), and tumor size (p = 0.043). Additionally, both tumor KIF2A protein (p = 0.035) and mRNA (p = 0.039) high expressions were correlated with worse disease-free survival (DFS) but not with overall survival (both p > 0.05). Moreover, tumor KIF2A protein expression was higher in relapsed patients than in non-relapsed patients within 3 years (p = 0.015) and 5 years (p = 0.031), whereas no difference was found between the dead and survivors within 3 years (p = 0.057) or 5 years (p = 0.107). Lastly, after adjustment, tumor KIF2A mRNA high exhibited a trend that correlated with DFS but without statistical significance (p = 0.051). Conclusion KIF2A correlates with more frequent lymph node metastasis and worse DFS in BLBC patients, shedding light on its potency as a biomarker for BLBC.

Abstract
Background Kinesin family member 2A (KIF2A) induces gastric cancer (GC) growth and invasion, while its clinical relevance in GC patients is not reported. This study aimed to investigate the linkage of KIF2A with clinicopathological features, prognosis, and chemosensitivity of GC. Methods A total of 160 surgical GC patients were reviewed, with their tumor and adjacent tissues acquired for immunohistochemical (IHC) assay to measure KIF2A expression, then scored by a semi‐quantitative method (IHC score: 0–12). KIF2A siRNA or nonsense‐siRNA were transfected into HGC‐27 and NCI‐N87 cells underwent various concentrations of capecitabine or oxaliplatin treatment followed by chemosensitivity assessment. Results Kinesin family member 2A expression was elevated in the tumor tissue compared to the adjacent tissue (IHC score: 5.6 ± 3.1 vs. 2.9 ± 1.7, p < 0.001). Besides, tumor KIF2A expression was related to larger tumor size (p = 0.014), higher N stage (p = 0.004) and TNM stage (p = 0.011); however, it was not linked with other clinicopathological features (all p > 0.05). Signally, tumor KIF2A high expression predicted poor overall survival (p = 0.037). After adjustment via multivariate Cox's regression, tumor KIF2A high expression independently linked with worse disease‐free survival (p = 0.033). Finally, KIF2A knockdown improved the oxaliplatin chemosensitivity vastly but only slightly affected capecitabine chemosensitivity in HGC‐27 and NCI‐N87 cells. Conclusion Kinesin family member 2A reflects larger tumor size, advanced TNM stage, improved chemosensitivity, and predicts unfavorable survival in GC.

Abstract
Glioma, also known as glioblastoma multiforme (GBM), is the most prevalent and most lethal primary brain tumor in adults. Gliomas are highly invasive tumors with the highest death rate among all primary brain malignancies. Metastasis occurs as the tumor cells spread from the site of origin to another site in the brain. Metastasis is a multifactorial process, which depends on alterations in metabolism, genetic mutations, and the cancer microenvironment. During recent years, the scientific study of non-coding RNAs (ncRNAs) has led to new insight into the molecular mechanisms involved in glioma. Many studies have reported that ncRNAs play major roles in many biological procedures connected with the development and progression of glioma. Long ncRNAs (lncRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs) are all types of ncRNAs, which are commonly dysregulated in GBM. Dysregulation of ncRNAs can facilitate the invasion and metastasis of glioma. The present review highlights some ncRNAs that have been associated with metastasis in GBM. miRNAs, circRNAs, and lncRNAs are discussed in detail with respect to their relevant signaling pathways involved in metastasis.

Abstract
The current study set out to clarify the role of miR-424-5p promoter methylation in epithelial mesenchymal transition (EMT) of hepatocellular carcinoma (HCC) cells. The findings of quantitative real-time-polymerase chain reaction and methylation-sensitive high-resolution melting assays elicited that miR-424-5p was poorly expressed in HCC tissues and cells while highly methylated. Meanwhile, upon demethylation, miR-424-5p expression levels were partly recovered in HCC cells. In addition, miR-424-5p upregulation reduced cell viability and elevated apoptosis of HCC cells, in parallel with increased N-cadherin and decreased E-cadherin levels. Dual-luciferase reporter assay further validated that miR-424-5p bound to the kinesin family member 2A (KIF2A), and miR-424-5p overexpression downregulated KIF2A. In addition, KIF2A overexpression reversed the miR-424-5p-driven changes in terms of cell viability, apoptosis and EMT-related protein levels. Furthermore, xenograft tumors were established via injection of Huh7 cells, followed by miR-424-5p overexpression in vivo, which inhabited KIF2A downregulation and attenuated tumor growth along with decreased Ki67 positive expression, diminished N-cadherin and elevated E-cadherin levels. Overall, our findings supported the conclusion that miR-424-5p promoter methylation reduced miR-424-5p expression and upregulated KIF2A, thereby promoting HCC EMT.

Abstract
KIF2A has been shown to be involved in the regulation of AML pathology, however, the mechanistic role of KIF2A in AML has not been fully identified. The present study aimed to identify the underlying mechanism of KIF2A regulation of AML cell function and chemosensitivity. A total of 58 patients with AML and 30 healthy subjects were enrolled for clinical analysis. AML cells (KG‑1 and Kasumi‑1) were transfected with KIF2A or control small interfering (si)RNA. PI3K/AKT pathway activator (740 Y‑P) and RhoA overexpression plasmid were added to rescue the effect of KIF2A siRNA. Cell proliferation, apoptosis, chemosensitivity to ADR and AraC, expression levels of mRNA/proteins associated with PI3K/AKT and RhoA/ROCK pathways were measured by Cell Counting Kit‑8, flow cytometry, reverse transcription‑quantitative PCR and western blotting. KIF2A was overexpressed, and correlated with higher levels of bone marrow blast, poor risk classification, lower treatment response and unfavorable survival profile in patients with AML. KIF2A siRNA inhibited proliferation but enhanced apoptosis and chemosensitivity to ADR and AraC in KG‑1 and Kasumi‑1 cells, which also inactivated PI3K/AKT and RhoA/ROCK pathways. Subsequent rescue experiments showed that 740 Y‑P and RhoA overexpression plasmid promoted cell survival and decreased chemosensitivity, which reversed the effect of KIF2A siRNA in KG‑1 and Kasumi‑1 cells. KIF2A was correlated with worse clinical features and survival in patients with AML; its knockdown promoted apoptosis and chemosensitivity by inactivating PI3K/AKT and RhoA/ROCK signaling pathways in AML cells. These data suggested KIF2A may be a potential prognostic marker and treatment target for AML management.

Abstract
Non-small cell lung cancer (NSCLC) is the most common type of lung cancer.
Increasing evidence suggests that long non-coding RNAs (lncRNAs) function in the
tumorigenesis of NSCLC. LINC00958, a newly identified lncRNA, has been reported
to be closely linked to tumorigenesis in several cancers. However, its specific
role in NSCLC remains unclear. In this study, we determined the expression of
LINC00958 in NSCLC by RT-qPCR analysis and evaluated cell proliferation and
migration by CCK-8 and transwell assays, respectively. We established a
xenograft tumor model to examine the effect of LINC00958 on tumor growth in
vivo. Luciferase reporter assays were performed to determine the interaction
between LINC00958 and miR-204-3p and the interaction between miR-204-3p and
KIF2A. We found that LINC00958 was up-regulated in NSCLC tissues and cell lines.
Down-regulation of LINC00958 inhibited cell proliferation and migration in vitro
and suppressed tumor growth in vivo. Besides, miR-204-3p was identified as a
target of LINC00958 and miR-204-3p inhibitor could reverse the inhibitory effect
of LINC00958 knockdown on proliferation and migration of NSCLC cells. We also
validated that KIF2A, a direct target of miR-204-3p, was responsible for the
biological role of LINC00958. KIF2A antagonized the effect of miR-204-3p on
NSCLC cell proliferation and migration and was regulated by
LINC00958/miR-204-3p. Taken together, these data indicate that the
LINC00958/miR-204-3p/KIF2A axis is critical for NSCLC progression, which might
provide a potential therapeutic target of NSCLC.

Liu W, Xu C, Meng Q, Kang P. The clinical value of kinesin superfamily protein 2A in hepatocellular carcinoma. Clin Res Hepatol Gastroenterol 2021; 45:101527. [PMID: 33713978 DOI: 10.1016/j.clinre.2020.08.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 07/28/2020] [Accepted: 08/24/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND This study aimed to investigate the clinical value of kinesin superfamily protein 2A (KIF2A) in hepatocellular carcinoma (HCC) patients. METHODS This study retrospectively analyzed 196 HCC patients who underwent hepatic resection, and their preoperative clinical characteristics were collected from the medical records. Immunohistochemical (IHC) assay was performed to detect KIF2A expression, subsequently KIF2A expression was evaluated by a semi-quantitative IHC score (according to IHC staining density and intensity of positively stained cells) and then graded as KIF2A-/KIF2A+/KIF2A++/KIF2A+++ for analysis. Overall survival (OS) was calculated from the date of resection to the date of death. RESULTS Compared to adjacent tissue, both KIF2A IHC score and grade were higher in tumor tissue (Both P < 0.001). Tumor KIF2A expression was positively correlated with performance status score (P = 0.001), multifocal tumor nodule (P = 0.018), largest tumor size (P = 0.015) and Barcelona clinic liver cancer stage (P < 0.001). Regarding live function indexes, tumor KIF2A expression was positively associated with aspartate aminotransferase (P = 0.006). As to tumor markers, tumor KIF2A expression showed a trend to be positively correlated with alpha fetoprotein (P = 0.060) and carbohydrate antigen 199 (P = 0.053), but no statistical significance. Kaplan-Meier curve showed that tumor higher KIF2A expression was associated with worse OS (P < 0.001), which was further validated by multivariate Cox's regression analysis as higher an independent factor predicting shorter OS (P = 0.001). CONCLUSION KIF2A is upregulated in tumor tissue than adjacent tissue, importantly, tumor KIF2A is associated with worse liver function, raised tumor stage and poor OS in HCC patients.

Abstract
BACKGROUND Cervical cancer is one of the most common and fatal malignancies among females, and biomarkers are essential for assisting in its management. Kinesin family member 2A (KIF2A) has been exhibited to be a potential maker in various cancers; however, its role in cervical cancer has yet to be reported. Therefore, we aimed to assess the expression of KIF2A and its correlation with clinicopathological characteristics as well as survival profile in cervical cancer patients. METHODS A hundred and thirty-five cervical cancer patients who underwent simple trachelectomy or radical hysterectomy were retrospectively analyzed. Tumor tissues and paired adjacent tissues were acquired, in which KIF2A mRNA and protein expressions were determined by reverse transcription quantitative polymerase chain reaction and immunohistochemistry assay, respectively. Disease-free survival (DFS) and overall survival (OS) were documented with a median follow-up duration of 28.0 months. RESULTS KIF2A protein (P < 0.001) and mRNA (P < 0.001) expressions were both upregulated in tumor tissues compared to paired adjacent tissues in cervical cancer patients. In addition, tumor tissue KIF2A protein and mRNA expressions were positively associated with lymph node metastasis (P = 0.025 and P = 0.010, respectively) and FIGO stage (P = 0.022 and P = 0.015, respectively) in cervical cancer patients. Moreover, patients with tumor tissue KIF2A high expression (mRNA and protein) displayed worse DFS (P = 0.010 and P = 0.046, respectively) and OS (P = 0.042 and P = 0.030, respectively) compared to patients with tumor tissue KIF2A low expression (mRNA and protein). CONCLUSION Tumor tissue KIF2A expression could serve as a biomarker enhancing the disease surveillance and prognostication in cervical cancer management.

Abstract
Collagen type X alpha 1 (COL10A1) is a member of the collagen family and the main matrix component. However, COL10A1 expression and prognosis relationship remains unclear in gastric cancer (GC). Through the analysis of database of Oncomine, the Cancer Genome Atlas (TCGA) as well as the Gene Expression Omnibus (GEO), in contrast to the tissue of normal gastric, COL10A1 in gastric cancer, had been upregulated. The high expression of COL10A1 was obviously related to T stage (P = 0.025) and lymph node metastasis (P = 0.025). It has been illustrated by the analysis of logistic regression that COL10A1's heightened expression in gastric cancer had been essentially linked with pathological stage, tumor differentiation, and T classification. The Kaplan-Meier curve in the Kaplan-Meier plotter database (P = 0.0371) and GSE84437 (P = 0.002) indicate that patients with high COL10A1 expression possess poor prognosis, specifically GC patients with lymph node metastasis have it. TCGA's Multivariate analysis (P = 0.025) and GSE84437 dataset (P = 0.034) show that high expression COL10A1 is a key independent predictor of poor overall survival. Searching KEGG pathway enrichment by GSEA, the results suggested that 29 pathways were enriched. qRT-PCR technique was used for verification of the COL10A1's high expression in gastric cancer in contrast to the normal gastric tissues. In conclusion, COL10A1 is of great importance in predicting the survival rate of GC patients.

Identification of Kinesin Family Member 2A (KIF2A) as a Promising Therapeutic Target for Osteosarcoma. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7102757. [PMID: 33204709 PMCID: PMC7655250 DOI: 10.1155/2020/7102757] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 11/07/2019] [Accepted: 08/12/2020] [Indexed: 12/30/2022]
Abstract
Background Osteosarcoma is known as a type of common human bone malignancy, and more therapeutic targets are still required to combat this disease. In recent years, the involvement of KIF2A in cancer progression has been widely revealed; however, its potential effect on osteosarcoma development remains unknown. This study is to assess the KIF2A expression levels in human osteosarcoma tissues and explore its potential role in osteosarcoma development. Methods Immunohistochemical (IHC) assays were conducted to evaluate the expression levels of KIF2A in a total of 74 samples of osteosarcoma tissues and adjacent nontumor tissues. According to the staining intensity in tumor tissues, patients were divided into highly expressed and low expression KIF2A groups. The possible links between the KIF2A expression and the clinical pathological features were explored and analyzed, and the effects of KIF2A on osteosarcoma cell proliferation, migration, and invasion were detected through colony formation assay, MTT assay, wound closure assay, and transwell assay, respectively. The effects of KIF2A on tumor growth and metastasis were detected by the use of animal models. Results KIF2A was highly expressed in human osteosarcoma tissues. Meanwhile, KIF2A was obviously correlated to the tumor size (P = 0.001∗) and clinical stage (P = 0.014∗) of osteosarcoma patients. Our results also revealed that the ablation of KIF2A dramatically blocked the proliferation, migration, and invasion capacity of osteosarcoma cells in vitro and blocked tumor growth and metastasis in mice. Conclusions We investigated the involvement of KIF2A in the development and metastasis of osteosarcoma and therefore thought KIF2A as a promising therapeutic target for osteosarcoma treatment.

Abstract
Background Diffuse large B-cell lymphoma (DLBCL) is a common malignant tumor in the immune system with high mortality. We investigated the functional effects of long non-coding RNA paternally expressed imprinted gene 10 (PEG10) on DLBCL progression. Material/Methods Real-time quantitative polymerase chain reaction was used to measure the level of PEG10, kinesin family member 2A (KIF2A) and microRNA-101-3p (miR-101-3p) in DLBCL tissues and cell lines. The relative protein level was detected by western blot analysis. The biological behaviors including cell proliferation, apoptosis, migration, and invasion were determined by MTT assay, flow cytometry analysis, and Transwell assays, respectively. Bioinformatics analysis and dual-luciferase reporter assay were performed to evaluate the interaction among PEG10, miR-101-3p, and KIF2A. Results PEG10 and KIF2A level were significantly upregulated, while miR-101-3p was downregulated in DLBCL tissues and cells. PEG10 positively regulated KIF2A level in DLBCL. PEG10, or KIF2A deletion significantly inhibited the proliferative, migratory, and invasive abilities of DLBCL cells and elevated cell apoptosis in DLBCL cells. KIF2A upregulation partially reversed the effects of PEG10 downregulation on cell growth, metastasis, and apoptosis in DLBCL. Moreover, PEG10 negatively regulated miR-101-3p level and miR-101-3p upregulation exerted inhibition effects on the progression of DLBCL. Besides, miR-101-3p was a target of PEG10 and miR-101-3p could directly target KIF2A. PEG10 promoted KIF2A level by sponging miR-101-3p. Conclusions Our findings revealed that PEG10 played an oncogenic role in DLBCL progression, which might be a potential target for the treatment of DLBCL.

Abstract
Background: Temozolomide (TMZ) resistance is a serious hindrance in clinical chemotherapy for glioma. Circular RNA homeodomain interacting protein kinase 3 (circHIPK3) can be involved in regulating the progression of glioma, but the molecular mechanism of circHIPK3 in TMZ-resistant-glioma is completely unclear. Materials and Methods: The levels of circRNA, miRNA, and mRNA were examined using quantitative real-time polymerase chain reaction. 3-(4,5-dimethylthiazol-2-y1)-2, 5-diphenyl tetrazolium bromide assay was used for assessing the half inhibitory concentration (IC50) of TMZ and cell proliferation. Cell apoptosis and metastasis (migration and invasion) were detected by flow cytometry and transwell assay, respectively. Western blot and dual-luciferase reporter assay were performed several times to analyze the expression levels of associated proteins and the targeted relation. Results: The upregulation of circHIPK3 was found in TMZ-resistant glioma tissues and cells. Both circHIPK3 knockdown and kinesin family member 2A (KIF2A) inhibition could facilitate TMZ sensitivity and apoptosis but repress proliferation and metastasis in TMZ-resistant glioma cells. CircHIPK3 targeted microRNA-524-5p (miR-524-5p) and KIF2A functioned as a downstream target of miR-524-5p. Decrease of miR-524-5p relieved the effects of si-circHIPK3 on TMZ-resistant glioma cells by upregulating KIF2A. Downregulation of circHIPK3 refrained the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (AKT) signal pathway partly through miR-524-5p/KIF2A axis. Conclusions: Knockdown of circHIPK3 promoted TMZ sensitivity in glioma by modulating proliferation, metastasis, and apoptosis through miR-524-5p/KIF2A-mediated PI3K/AKT pathway. CircHIPK3 may be the potential target for the diagnosis and therapy of TMZ-resistant glioma.

Abstract
Objective Gastric cancer (GC) is a gastrointestinal tumor. This study is aimed to explore the regulatory mechanism of long non-coding RNA BLACAT1 (BLACAT1)/microRNA-149-5p (miR-149-5p)/KIF2A cascade on GC. Methods The expression of BLACAT1, miR-149-5p and KIF2A in GC was detected by qRT-PCR. The proliferation, migration and invasion of GC cells in vitro were analyzed by MTT, wound-healing and transwell assay, respectively. The xenograft tumor model was constructed in nude mice to confirm the inhibition effect of BLACAT1 knockdown on GC in vivo. Then, dual-luciferase reporter assay was used to detect the interactions among BLACAT1, miR-149-5p and KIF2A. Western blot assay was performed to determine the protein expression of KIF2A. Results The expression of BLACAT1 and KIF2A was up-regulated in GC, but miR-149-5p expression was down-regulated. Silencing of BLACAT1 retarded the proliferation, migration and invasion of GC cells in vitro and the growth of tumor xenograft in vivo. Moreover, BLACAT1 acted as the molecular sponge of miR-149-5p to up-regulate KIF2A expression. At last, feedback experiments suggested that BLACAT1 accelerated the proliferation, migration and invasion of GC cells by regulating miR-149-5p/KIF2A axis. Conclusion BLACAT1 facilitated the tumorigenesis of GC through regulating miR-149-5p/KIF2A axis, which indicated BLACAT1/miR-149-5p/KIF2A cascade may be a new therapeutic target.

Abstract
Abnormal expression of neuropilin and tolloid‐like 1 (NETO1) has been detected in some human carcinomas. However, the expression of NETO1 and the underlying mechanism in epithelial ovarian cancer (EOC) remain unknown. In this study, we found that a higher NETO1 expression in EOC tissue samples compared to normal ovarian tissue samples was significantly correlated with worse overall survival. Additionally, Cox regression analysis suggested that NETO 1 was independently associated with overall survival. NETO1 overexpression enhanced the EOC cells’ migration and invasion capability in vitro via regulation of actin cytoskeleton. Mechanistically, silencing NETO1 reduced the expression of β‐tubulin, F‐actin and KIF2A. In conclusion, our results demonstrated the critical role of NETO1 in EOC invasion, and therapies aimed at inhibiting its expression or activity might significantly control EOC growth, invasion and metastatic dissemination.

Abstract
Aim Kinesin family member 2A (KIF2A) is a member of the kinesin-13 superfamily protein. KIF2A played a role in the development of many tumors. However, the role of KIF2A in esophageal squamous cell carcinoma (ESCC) remains unclear. In this study, we aimed to investigate the role of KIF2A in ESCC. Methods We used bioinformatics analysis to study the expression levels and prognosis of KIF2A in ESCC and normal tissues. We also used our own samples to verify the results by immunohistochemistry. Then, the biological functions of KIF2A in ESCC was studied by cell experiments and animal experiments. Results Both the TCGA database and our samples showed that KIF2A was relatively highly expressed in ESCC tissues and was significantly associated with disease-free survival (P =0.037) in TCGA database. Colony formation assay, CCK8 and Western blotting results showed that knockdown of KIF2A can significantly reduce colony forming ability and proliferation ability. The results of animal experiments showed that knocking down KIF2A can significantly reduce the tumor volume of mice. Conclusion KIF2A might be used as a prognostic factor for ESCC, and knockdown of KIF2A could inhibit ESCC proliferation in vitro and in vivo, respectively. KIF2A could serve as a potential prognostic biomarker and therapeutic target for future ESCC.

Abstract
BACKGROUND The kinesin family (KIF) is reported to be aberrantly expressed and significantly correlated with survival outcomes in patients with various cancers. This meta-analysis was carried out to quantitatively evaluate the prognostic values of partial KIF members in cancer patients. METHODS Two well-known KIF members, KIF2A and KIF20A, were investigated to evaluate their potential values as novel prognostic biomarkers in human cancer. A comprehensive literature search was carried out of the PubMed, EMBASE, Cochrane Library, and Web of Science databases up to April 2019. Pooled hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the association of KIF2A and KIF20A expression with overall survival (OS) and clinicopathological parameters. RESULTS Twenty-five studies involving 7262 patients were finally incorporated, including nine about KIF2A and sixteen about KIF20A. Our results indicated that patients with high expression of KIF2 and KIF20A tended to have shorter OS than those with low expression (HR = 2.23, 95% CI = 1.87-2.65, P < .001; HR = 1.77, 95% CI = 1.57-1.99, P < .001, respectively). Moreover, high expression of these 2 KIF members was significantly associated with advanced clinical stage (OR = 1.98, 95% CI: 1.57-2.50, P < .001; OR = 2.63, 95% CI: 2.03-3.41, P < .001, respectively), positive lymph node metastasis (OR = 2.32, 95% CI: 1.65-3.27, P < .001; OR = 2.13, 95% CI: 1.59-2.83, P < .001, respectively), and distant metastasis (OR = 2.20, 95% CI: 1.21-3.99, P = .010; OR = 5.25, 95% CI: 2.82-9.77, P < .001, respectively); only high KIF20A expression was related to poor differentiation grade (OR = 1.82, 95% CI: 1.09-3.07, P = .023). CONCLUSIONS High expression of KIF2 and KIF20A in human cancer was significantly correlated with worse prognosis and unfavorable clinicopathological features, suggesting that these 2 KIF members can be used as prognostic biomarkers for different types of tumors.

Abstract
Nasopharyngeal carcinoma (NPC) is a common tumor in south China. Kinesin family member 2A (KIF2A) belongs to the kinesin-13 family and is associated with the growth and invasion of a number of different types of human cancer, including ovarian, breast and prostate cancer. The aim of the present study was to evaluate the expression of KIF2A in NPC and explore the relationship between KIF2A and the basic characteristics of 5-8F cells. Immunohistochemistry was performed on tissues from 97 patients with NPC to assess KIF2A protein expression. KIF2A was knocked down by a specific short interfering (si)RNA in 5-8F cell lines. Cell proliferation, apoptosis and cycle were analyzed by MTT assay and flow cytometry. The invasive ability and angiogenesis were evaluated by Matrigel assay and reverse transcription-quantitative PCR. The level of KIF2A was associated with the growth and migration of primary tumor, nodal status and tumor stage. The viability of KIF2A-knockdown cells was decreased compared with that of the control cells. The number of apoptotic cells, as well as the percentage of cells in the G0/G1 phase, was higher in the KIF2A siRNA group compared with the control group. The invasive and angiogenetic ability of 5-8F cells in the KIF2A siRNA group was decreased compared with the control group. In conclusion, the expression of KIF2A correlated with the poor clinicopathological features in NPC. Therefore, KIF2A may serve an important role in the progression of NPC and proliferation of 5-8F cells, which might present a potential therapeutic target for patients with NPC.
