Basic Transcription Factor 3 Like 4 Enhances Malignant Phenotypes through Modulating Tumor Cell Function and Immune Microenvironment in Glioma.

Recent investigations into the tumor microenvironment have provided insights into the limited response of glioma progression to immunotherapy. However, the specific involvement of basic transcription factor 3 like 4 (BTF3L4) in glioma progression and its correlation with immune cell infiltration remain areas of uncertainty that require further exploration. In the current study, BTF3L4 expression was delineated by using gene expression profiling/interactive analysis and multiplex-immunohistologic staining of tissue microarrays. The prognostic value of BTF3L4 was then assessed by using Cox regression models and Kaplan-Meier methods, and in vitro experiments were conducted to investigate how BTF3L4 protein affects the proliferation, migration, and invasion capabilities of glioma cells. Furthermore, the CIBERSORT and ESTIMATE methods were used to quantify immune cells that correlate to BTF3L4 expression, and multiplex-immunohistologic staining was applied to investigate its correlation with infiltrated immune cells in glioma tissues. These findings revealed higher BTF3L4 expression in glioma tissues compared with non-tumor brain tissues, which correlated with clinical characteristics and worse patient prognosis. Furthermore, the down-regulation of BTF3L4 protein in the glioma cell line had a detrimental effect on cell migration, invasion, and proliferation. In addition, the association between BTF3L4 and key immune molecules in glioma, particularly with the infiltration of CD66B+ neutrophils and programmed death ligand 1 expression, was identified. These results highlight the prognostic significance of BTF3L4 and propose BTF3L4 as a potential target for glioma immune therapy.

Dynamic Phase Transformations of Prussian Blue Analogue Crystals in Hydrotherms.

Prussian blue analogue (PBA)/metal-organic frameworks (MOFs) are multifunctional precursors for the synthesis of metal/metal compounds, carbon, and their derived composites (P/MDCs) in chemical, medical, energy, and other applications. P/MDCs combine the advantages of both the high specific surface area of PBA/MOF and the electronic conductivity of metal compound/carbon. Although the calcination under different atmospheres has been extensively studied, the transformation mechanism of PBA/MOF under hydrothermal conditions remains unclear. The qualitative preparation of P/MDCs in hydrothermal conditions remains a challenge. Here, we select PBA to construct a machine-learning model and measure its hydrothermal phase diagram. The architecture-activity relationship of substances among nine parameters was analyzed for the hydrothermal phase transformation of PBA. Excitingly, we established a universal qualitative model to accurately fabricate 31 PBA derivates. Additionally, we performed three-dimensional reconstructed transmission electron microscopy, X-ray absorption fine structure spectroscopy, ultraviolet photoelectron spectroscopy, in situ X-ray powder diffraction, and theoretical calculation to analyze the advantages of hydrothermal derivatives in the oxygen evolution reaction and clarify their reaction mechanisms. We uncover the unified principles of the hydrothermal phase transformation of PBA, and we expect to guide the design for a wide range of composites.

CircBIRC6 facilitates the malignant progression via miR-488/GRIN2D-mediated CAV1-autophagy signal axis in gastric cancer.

Circular RNAs (circRNAs) represent a novel class of non-coding RNAs that play significant roles in tumorigenesis and tumor progression. High-throughput sequencing of gastric cancer (GC) tissues has identified circRNA BIRC6 (circBIRC6) as a potential circRNA derived from the BIRC6 gene, exhibiting significant upregulation in GC tissues. The expression of circBIRC6 is notably elevated in GC patients. Functionally, it acts as a molecular sponge for miR-488, consequently upregulating GRIN2D expression and promoting GC proliferation, migration, and invasion. Moreover, overexpression of circBIRC6 leads to increased GRIN2D expression, which in turn enhances caveolin-1 (CAV1) expression, resulting in autophagy deficiency due to miR-488 sequestration. This cascade of events significantly influences tumorigenesis in vivo. Our findings collectively illustrate that the CircBIRC6-miR-488-GRIN2D axis fosters CAV1 expression in GC cells, thereby reducing autophagy levels. Both circBIRC6 and GRIN2D emerge as potential targets for treatment and independent prognostic factors for GC patients.

Stable Bismuth-Doped Lead Halide Perovskite Core-Shell Nanocrystals by Surface Segregation Effect.

Lead halide perovskite nanocrystals (NCs) exhibit excellent optoelectronic performance, however, the broad application is limited by their poor stability. Herein, a strategy for stable core-shell structured bismuth-doped lead halide perovskite NCs is reported. The stable core-shell perovskite NCs are prepared based on heterovalent substitutions and surface segregation effect. Core-shell features are revealed through advanced characterization and structure analyses. Meanwhile, the transfer of carriers between the core and the shell is observed by ultrafast transient absorption spectroscopy. The core-shell structured perovskite NCs exhibit outstanding structure stability and retain 97% of the original photocatalytic efficiency after cycle experiments under moisture ambient and light irradiation. Such a core-shell structure constructs gradient energy levels. These findings are expected to facilitate the development of stable lead halide perovskite devices.

Characterization and pathogenicity of a novel avian nephritis virus isolated in China.

ABSTRACTAvian nephritis virus infections of chicken flocks cause enteric and kidney disease, uneven growth, and runting stunting syndrome, leading to economic losses in the poultry industry. In this study, one ANV strain, designated as AH202017, was isolated from a diseased broiler flock in Anhui province, China, in 2020. Virus production in LMH cell culture was confirmed by real-time RT-PCR and immunofluorescence assay. The complete genome sequencing analysis indicated that AH202017 shares 77.5-85.5% identity with 12 reference strains in GenBank. Phylogenetic analysis of the capsid protein revealed that AH202017 is more closely related to VIC-6a/Australia/2014 belonging to ANV genotype 2. However, the phylogenetic tree, based on the ORF1a protein and ORF1b protein, indicated that AH202017 manifests a close relationship with GXJL815/China/2017 belonging to genotype 8. In infection experiments, four infected chickens showed depression and one chicken died at 6 days post-infection, corresponding to 5% mortality. The virus was shed daily in the faeces of infected chickens, and was found distributed in multiple organs. Macroscopic and microscopic lesions in the kidneys were observed. This is the first paper that describes the genomic characteristics and pathogenicity of a novel ANV strain in China. RESEARCH HIGHLIGHTSA novel ANV strain was isolated for the first time from diseased broilers in China.The ANV strain caused nephritis and 5% mortality rate in 1-day-old SPF chickens.

Rbm46, a novel germ cell-specific factor, modulates meiotic progression and spermatogenesis.

It has been suggested that many novel RNA-binding proteins (RBPs) are required for gametogenesis, but the necessity of few of these proteins has been functionally verified. Here, we identified one RBP, Rbm46, and investigated its expression pattern and role in zebrafish reproduction. We found that rbm46 is maternally provided and specifically expressed in the germ cells of gonadal tissues using in situ hybridization, reverse transcription-PCR, and quantitative real-time polymerase chain reaction (qRT-PCR). Two independent rbm46 mutant zebrafish lines were generated via the transcription activator-like effector nuclease technique. Specific disruption of rbm46 resulted in masculinization and infertility in the mutants. Although the spermatogonia appeared grossly normal in the mutants, spermatogenesis was impaired, and meiosis events were not observed. The introduction of a tp53M214K mutation could not rescue the female-to-male sex-reversal phenotype, indicating that rbm46 acts independently of the p53-dependent apoptotic pathway. RNA sequencing and qRT-PCR subsequently indicated that Rbm46 might be involved in the posttranscriptional regulation of functional genes essential for germ cell development, such as nanos3, dazl, and sycp3, during gametogenesis. Together, our results reveal for the first time the crucial role of rbm46 in regulating germ cell development in vivo through promotion of germ cell progression through meiosis prophase I.

High RhCG expression predicts poor survival and promotes migration and proliferation of gastric cancer via keeping intracellular alkaline.

Advanced gastric cancer (GC) is aggressive with a high mortality rate. Rhesus family, C glycoprotein (RhCG) participates in tumor progression in many cancers, however its function in GC is still unknown. Here, we showed that RhCG was overexpressed in GC tissues at mRNA (P = 0.036) and protein levels (P < 0.05) compared with normal tissues. High RhCG level was correlated with poor differentiation (P = 0.037), TNM stage (P < 0.001), high HER-2 level (P = 0.018) and worse prognosis (P < 0.001). Cox proportional hazard model indicated that RhCG level was an independent prognostic biomarker. RhCG knockdown significantly decreased pHi and impeded tumor cellular proliferation, migration and invasion and repressed ß-catenin and c-myc expression in GC cells. Moreover, GC cells with high RhCG level had reduced oxaliplatin efficacy suggesting a role for RhCG as a therapeutic target for GC. Our findings revealed a function of RhCG in cancer pathogenesis, invasion and metastasis in human GC. We suggest that RhCG act may as a novel prognostic indicator and a therapeutic target for gastric adenocarcinoma.

Isolation and characterization of a recombinant Muscovy duck parvovirus circulating in Muscovy ducks in South China.

In 2019, flocks of Muscovy ducks presented with clinical signs typical of MDPV infection. The MDPV GD201911 strain was isolated by inoculating samples from positive birds into Muscovy duck embryos. Challenge with the isolate GD201911 caused typical MDPV disease symptoms and resulted in 25%-40% mortality, depending on the challenge dose, indicating the high pathogenicity of GD201911 for Muscovy ducks. Genome sequencing and phylogenetic analysis demonstrated that GD201911 clustered with recombinant MDPV strains, indicating that recombinant MDPV is circulating in China. Epidemiological monitoring should be performed continuously to assist with decision making for disease control.

EphA8 acts as an oncogene and contributes to poor prognosis in gastric cancer via regulation of ADAM10.

EphA8 is a member of the erythropoietin-producing hepatocellular receptor (Eph) family of receptor tyrosine kinases. Ephs and their ephrins ligands play crucial roles in many cellular processed by mediating intracellular signaling resulting from cell-cell interactions. But the underlying mechanisms of EphA8 in gastric cancer (GC) remains unclearly. 298 clinical specimens in tissues microarray, and was found to be significantly higher in GC tissues compared with nontumor tissues (p < 0.001). EphA8 expression was also strongly associated with differentiation level (p = 0.025), tumor-node-metastasis stage (p = 0.019), and poor 5 years survival (p < 0.001). A panel of GC cell lines showed reduced proliferation, invasion, and migration capacities after RNA-mediated knockdown of EphA8, concomitant with downregulation of the proliferation-related proteins (cyclin A, cyclin D1, and cyclin-dependent kinase 4) and the metastasis-related (matrix metalloproteinases MMP2, and MMP9). EphA8 knockdown also decreased expression of the protease ADAM10 (a disintegrin and metalloproteinase domain-containing protein 10) and ADAM10-related protein AKT, suggesting an interaction between EphA8 and ADAM10. In conclusion, we found that EphA8, which is highly expressed in GC tissues, stimulates proliferation, invasion, and migration of cancer cells, and is an independent risk factor for poor prognosis of GC. These dates suggest that EphA8 could be new diagnostic and/or therapeutic targets for GC.

Influence of design probe and sequence mismatches on the efficiency of fluorescent RPA.

Recombinase polymerase amplification (RPA) is an isothermal amplification technique. Because of its short detection cycle and high specificity, it has been applied in various fields. However, the design of probe on the efficiency of RPA is not well understood and the effect of sequence mismatches of oligonucleotides on the performance of RPA is rarely discussed. In this study, we found that different primers with the same probe have a slight effect on the efficiency of fluorescent RPA, and different probes with the same amplified region have a great influence on the efficiency of fluorescent RPA. We summarized the design rules of probes suitable for fluorescent RPA by analyzing the experimental data. The rule is that the best distance between fluorescent groups in the probe is 1-2 bases, and the G content should be reduced as far as possible. In addition, we verified this rule by designing a series of probes. Furthermore, we found the base mismatches of the probe had a significant effect on RPA, which can lead to false positives and can change the amplification efficiency. However, 1-3 mismatches covering the center of the primer sequence only affect the amplification efficiency of RPA, not its specificity. And with an increase in the number of primer mismatches, the efficiency of RPA will decrease accordingly. This study suggests that the efficiency of fluorescent RPA is closely related to the probe. We recommend that when designing a fluorescent probe, one must consider the presence of closely related non-targets and specific bases.

Combination Glioma Therapy Mediated by a Dual-Targeted Delivery System Constructed Using OMCN-PEG-Pep22/DOX.

Accumulating studies have investigated the efficacy of receptor-mediated delivery of hydrophobic drugs in glioma chemotherapy. Here, a delivery vehicle comprising polyethylene glycol (PEG) and oxidized nanocrystalline mesoporous carbon particles (OMCN) linked to the Pep22 polypeptide targeting the low-density lipoprotein receptor (LDLR) is designed to generate a novel drug-loaded system, designated as OMCN-PEG-Pep22/DOX (OPPD). This system effectively targets glioma cells and the blood-brain barrier and exerts therapeutic efficacy through both near-infrared (NIR) photothermal and chemotherapeutic effects of loaded doxycycline (DOX). Pathological tissue microarrays show an association of LDLR overexpression in human glioma tissue with patient survival.NIR irradiation treatment and magnetic resonance imaging results show that OPPD reaches the effective glioma-killing temperature in a glioma-bearing rat with a skull bone removal model and considerably reduces glioma sizes relative to the drug-loaded system without the Pep22 peptide modification and the control respectively. Thus, OPPD not only effectively targets LDLR-overexpressing glioma but also exerts a dual therapeutic effect by transporting DOX into the glioma and generating thermal effects with near-infrared irradiation to kill tumor cells. These collective findings support the utility of the novel OPPD drug-loaded system as a promising drug delivery vehicle for clinical application in glioma therapy.

Finite Difference Method for Time-Space Fractional Advection-Diffusion Equations with Riesz Derivative.

In this article, a numerical scheme is formulated and analysed to solve the time-space fractional advection-diffusion equation, where the Riesz derivative and the Caputo derivative are considered in spatial and temporal directions, respectively. The Riesz space derivative is approximated by the second-order fractional weighted and shifted Grünwald-Letnikov formula. Based on the equivalence between the fractional differential equation and the integral equation, we have transformed the fractional differential equation into an equivalent integral equation. Then, the integral is approximated by the trapezoidal formula. Further, the stability and convergence analysis are discussed rigorously. The resulting scheme is formally proved with the second order accuracy both in space and time. Numerical experiments are also presented to verify the theoretical analysis.

High KIF2A expression predicts unfavorable prognosis in diffuse large B cell lymphoma.

Kinesin family member 2A (KIF2A), a conserved motor protein, plays a critical role in the pathogenesis and prognosis of several malignant tumors. The aim of the present study was to investigate KIF2A expression in diffuse large B cell lymphoma (DLBCL), evaluate the association between KIF2A expression and the clinical parameters of the disease, and determine its prognostic value. KIF2A expression was evaluated in 134 DLBCL and 57 reactive hyperplasia samples using immunohistochemistry on a tissue microarray. The correlations between KIF2A expression with clinical parameters and prognosis were estimated using univariate and multivariate analyses. The expression of KIF2A was significantly higher in DLBCL tissue samples compared with those from subjects with reactive hyperplasia (P=0.002). Furthermore, increased expression of KIF2A protein in DLBCL was related to Ann Arbor stage (P=0.027) and international prognostic index (IPI) score (P=0.01). The survival analysis showed that KIF2A expression (P=0.016), serum LDH level (P=0.049), and IPI score (P<0.001) were independent prognostic markers for DLBCL. Our findings also confirmed that downregulating KIF2A expression decreased tumor cell viability, accompanied by downregulation of pAKT levels. Taken together, these data provide the first evidence that increased KIF2A expression predicts poor prognosis in patients with DLBCL, and a rationale for treatment of DLBCL by targeting KIF2A.

Diagnostic and prognostic significance of secretory clusterin expression in patients with hepatocellular carcinoma.

The upregulation of secretory clusterin (sCLU) is associated with tumor progression by contributing to angiogenesis, chemo-resistance, cell survival, and metastasis. However, its diagnostic or prognostic values for hepatocellular carcinoma (HCC) still remain to be clarified. The average serum sCLU level analyzed by an enzyme-linked immunosorbent assay was significantly higher (P < 0.001) in HCC patients than that in any of cases with cirrhosis, chronic hepatitis, or healthy control. The area under receiver operating characteristic curve and diagnostic sensitivity were 0.75 and 74.7 % in sCLU, and 0.74 and 58.7 % in α-fetoprotein (AFP), respectively. The combining detections of sCLU and AFP rose up to 90.7 % for HCC diagnosis. In liver, sCLU by immunohistochemistry was significantly higher (P < 0.001) in the HCC (77.3 %) group than that in their para-cancerous group (33.3 %). Abnormal serum or tissue sCLU expression was closely associated with tumor-node-metastasis (TNM) classification of malignant tumors and lymph node metastasis, as an independent prognosis factor (hazard ratio, 2.287; 95 % confidence interval, 1.044-5.007; P = 0.039), and higher sCLU expression significantly correlated (χ (2) = 4.252, P = 0.039) with poor survival of HCC patients analyzed by multivariate Cox regression or Kaplan-Meier method, suggesting that abnormal sCLU expression associated with tumor progression could be a potential diagnostic and prognostic biomarker for HCC.

Upregulation of CDK7 in gastric cancer cell promotes tumor cell proliferation and predicts poor prognosis.

CDK7 has been known as a component of CDK activating kinase (CAK) complex, the complex was composed of CDK7, Cyclin H and RING finger protein Mat1 that contribute to cell cycle progression by phosphorylating other CDKs. In addition, the complex is also an essential component of general transcription factor TFIIH which controls transcription via activating RNA polymerase II by serines 5 and 7 phosphorylation of the carboxyl-terminal domain (CTD) of its largest subunit. However, the role of CDK7 in the pathogenesis of gastric cancer has not been identified. Our study showed that CDK7 was significantly upregulated and positively correlated with tumor grade, infiltration depth, lymph node, Ki-67, and predicted poor prognosis in 173 gastric cancer specimens by immunohistochemistrical analyses. Furthermore, in vitro results indicated that CDK7 promoted proliferation of gastric cancer cells by CCK8, clone formation analyses and flow cytometric analyses, while CDK7 knockdown led to decreased cell proliferation. Our study will provide a theoretical basis for the study of CDK7 in gastric cancer.

Outcomes of catheter ablation of atrial fibrillation in patients with hypertrophic cardiomyopathy: a systematic review and meta-analysis.

AIMS: Over the past decade, catheter ablation (CA) has become an established therapy for symptomatic atrial fibrillation (AF). Atrial fibrillation is common in hypertrophic cardiomyopathy (HCM) patients, and restoring sinus rhythm is of great clinical benefit to them. Therefore, we conducted a systematic review and meta-analysis of the available data to evaluate the effectiveness and safety of CA for AF in patients with HCM. METHODS AND RESULTS: Six databases were searched to identify studies describing outcomes of CA of AF in HCM patients with a mean follow-up of ≥12 months after the index procedure. The following data were extracted: (i) single-procedure success, (ii) multiple-procedure success, and (iii) drug-free success. Fifteen studies involving 531 patients were included. Single-procedure freedom from atrial arrhythmia at the latest follow-up was 45.5% [95% confidence interval (CI): 34.8-56.2%]. With multiple procedures, the final success rate was 66.1% (95% CI: 55.3-76.9%) overall, 71.8% (95% CI: 61.6-82.0%) in paroxysmal AF, and 47.5% (95% CI: 36.0-59.0%) in non-paroxysmal AF. Without anti-arrhythmic drugs (AADs), single-procedure success rate at latest follow-up was 32.9% (95% CI: 21.7-41.1%); after multiple procedures, this raised to 50.4% (95% CI: 39.2-61.6%). The incidence of serious periprocedural complications was acceptable [5.1% (95% CI: 2.8-9.6%)]. Substantial heterogeneity (I(2)> 50%) was noted in the above groups. CONCLUSIONS: Catheter ablation of AF in patients with HCM is feasible, although more repeat procedures and AAD are needed to prevent AF recurrence.

Up-regulation of annexin A2 expression predicates advanced clinicopathological features and poor prognosis in hepatocellular carcinoma.

Hepatic annexin A2 (ANXA2) orchestrates multiple biologic processes and clinical symptoms and plays a key role in development, metastasis, and drug resistance of lethal hepatocellular carcinoma (HCC). However, the prognostic significance of ANXA2 for HCC has not been elucidated up to now. In this study, ANXA2 was frequently found to be up-regulated in HCC tissues compared with benign liver disease (BLD) tissues, which was consistent with the results in serum samples and tissue specimens of patients with HCC. Furthermore, ANXA2 expression was significantly correlated with differentiated degree, intrahepatic metastasis, portal vein thrombus, and tumor node metastasis (TNM) staging. More importantly, increased ANXA2 level was first confirmed to be closely associated with shortened overall survival of HCC (χ (2) = 12.872, P = 0.005) and identified as an independent prognostic factor (hazard ratio 1.338, 95 % confidence interval (CI) 1.013 ~ 1.766, P = 0.040), suggesting that ANXA2 up-regulation might represent an acquired metastasis phenotype of HCC, help to screen out high-risk population for HCC, or more effectively treat a subset of postsurgical HCC patients positive for ANXA2.

Phylogenetic and antigenic characterization of reassortant H9N2 avian influenza viruses isolated from wild waterfowl in the East Dongting Lake wetland in 2011-2012.

BACKGROUND: Wild waterfowl are recognized as the natural reservoir for influenza A viruses. Two distinct lineages, the American and Eurasian lineages, have been identified in wild birds. Gene flow between the two lineages is limited. The H9N2 virus has become prevalent in poultry throughout Eurasia, and mainly circulates in wild ducks and shorebirds in North America. METHODS: In this study, 22 H9N2 avian influenza viruses were isolated from wild waterfowl feces in East Dongting Lake Nature Reserve in November 2011 and March 2012. The phylogenetic, molecular, and antigenic characteristics of these viruses were analyzed based on analyses of the whole genome sequence of each isolate. RESULTS: Phylogenetic analyses indicated that these H9N2 viruses were generated by reassortment events. The HA, NA, PA, and NS genes were derived from the American gene pool, and the other four genes were derived from the Eurasian gene pool. Antigenic analyses indicated that these viruses were significantly different from the Eurasian lineage viruses. CONCLUSIONS: This study presents the isolation of novel intercontinental recombinant H9N2 viruses from wild waterfowl in the East Dongting Lake wetland. The novel genotype H9N2 virus has not been detected in poultry in the region yet, and may be transmitted to naïve birds in poultry farms. Therefore, our results highlight the need for ongoing surveillance of wild birds and poultry in this region.

[Expression change and significance of homebox gene-A10 in rat cryptorchidism].

OBJECTIVE: To explore the effects of HOXA10 gene expression in undescended and descended testis. METHODS: Twenty-four male Sprague Dawley rats were surgically prepared for unilateral cryptorchidism model. Their undescended and descended testes were removed at days 7 (infancy period, group B7) and 60 (sexual maturity period, group B60) post-operation. And contralateral descended testis served as controls (group A7, group A60). The expression of HOXA10 with histologic changes in experimental cryptorchidism were detected with one-step real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. RESULTS: Compared with the control group, the levels of HOXA10 gene for groups B7 and B60 decreased markedly to 0.78 ± 0.11 (P < 0.01) and 0.56 ± 0.03 (P < 0.01) respectively.However the levels of HOXA10 gene and protein in group B60 were significantly lower than those in group B7 (P < 0.01). CONCLUSIONS: There is a lower expression of HOXA10 in undescended testes than in normally developed counterparts. And the expression of HOXA10 decreases with the elapsing time of cryptorchidism.

WSCD2 Expression: Its Relevance to Tumor-Infiltrating Immune Cells and Glioma Prognosis.

BACKGROUND: Patients with glioma have limited treatment options and experience poor prognoses. Therefore, it is urgently needed to explore new diagnostic and therapeutic targets. OBJECTIVE: This study aimed to investigate the relevance of WSC domain-containing 2 (WSCD2) expression to glioma, clinicopathological characteristics, tumor-infiltrating immune cells (TILs), and patient prognosis. METHODS: We analyzed WSCD2 mRNA expression in glioma tissues and patient survival using the Gene Expression Profiling Interactive Analysis database. Furthermore, the relationship between the expressions of WSCD2 mRNA and TILs in gliomas was evaluated utilizing the Tumor Immune Estimation Resource database. Lastly, we employed multiplex immunohistochemistry to detect the protein expressions of WSCD2 and TILs in glioma tissues. RESULTS: WSCD2 mRNA expression in glioma tissues was lower than that in tissues of benign brain disease. High WSCD2 mRNA expression was also significantly associated with a favorable outcome. Additionally, WSCD2 mRNA expression was correlated with TIL expression in glioma; however, no such relationship was detected between the protein expressions of WSCD2 and TILs in glioma tissues. Cox regression multivariate analysis and Kaplan-Meier survival analysis showed that WSCD2 expression in glioma tissues could be an independent prognostic factor. CONCLUSION: This study highlights the correlation between WSCD2 expression and TILs and demonstrates the prognostic significance of WSCD2 in glioma. Furthermore, our results suggest that WSCD2 may be a potential immunotherapy target in glioma.
