A dynamically cross-linked catechol-grafted chitosan/gelatin hydrogel dressing synergised with photothermal therapy and baicalin reduces wound infection and accelerates wound healing.

Superior multifunctional hydrogel dressings are of considerable interest in wound healing. In clinical practice, it is useful to investigate hydrogel dressings that offer multifunctional benefits to expedite the process of wound healing. In this study, Catechol-grafted Chitosan, Gelatin, and Fe3+ as substrates to construct a hydrogel network. The network was dynamically cross-linked to form Ccg@Fe hydrogel substrate. Fe3O4 nanoparticles and baicalin, which possess antimicrobial and anti-inflammatory properties, were loaded onto the substrate to form a photothermal antibacterial composite hydrogel dressing (Ccg@Fe/Bai@Fe3O4 NPs). The Ccg@Fe hydrogel was characterised using Fourier transform infrared spectroscopy (FTIR) and Ultraviolet-visible spectrophotometry (UV-Vis). The morphological, mechanical, and adhesion properties of the hydrogel were determined using scanning electron microscopy (SEM) and a universal testing machine. The hydrogel's swelling, hemostasis, and self-healing properties were also evaluated. Additionally, the study determined the release rate of hydrogel-loaded antimicrobial and anti-inflammatory Baicalin (Ccg@Fe/Bai) and evaluated the photothermal antimicrobial properties of hydrogel-loaded Fe3O4 nanoparticles (Ccg@Fe/Bai@Fe3O4 NPs) through synergistic photothermal therapy (PTT). Histological staining of mice skin wound tissues using Masson and H&E revealed that the Ccg@Fe/Bai@Fe3O4 NPs hydrogel dressing demonstrated potential healing ability with the aid of PTT. The study suggests that this multifunctional hydrogel dressing has great potential for wound healing.

Exploring the evolving roles and clinical significance of circRNAs in head and neck squamous cell carcinoma.

Head and neck squamous cell carcinoma (HNSCC) represents the predominant malignancies in the head and neck region, and has limited therapeutic alternatives. Circular RNAs (circRNAs), a substantial category of non-coding RNA molecules, exert influential roles in human disease development and progression, employing various mechanisms such as microRNA sponging, interaction with RNA-binding proteins, and translational capabilities. Accumulating evidence highlights the differential expression of numerous circRNAs in HNSCC, and numerous dysregulated circRNAs underscore their crucial involvement in malignant advancement and resistance to treatment. This review aims to comprehensively outline the characteristics, biogenesis, and mechanisms of circRNAs, elucidating their functional significance in HNSCC. In addition, we delve into the clinical implications of circRNAs, considering their potential as biomarkers or targets for diagnosis, prognosis, and therapeutic applications in HNSCC. The discussion extends to exploring future challenges in the clinical translation of circRNAs, emphasizing the need for further research.

BNIPL is a promising biomarker of laryngeal cancer: novel insights from bioinformatics analysis and experimental validation.

BACKGROUND: Laryngeal cancer (LC) is a malignant tumor with high incidence and mortality. We aim to explore key genes as novel biomarkers to find potential target of LC in clinic diagnosis and treatment. METHODS: We retrieved GSE143224 and GSE84957 datasets from the Gene Expression Omnibus database to screen the differentially expressed genes (DEGs). Hub genes were identified from protein-protein interaction networks and further determined using receiver operating characteristic curves and principal component analysis. The expression of hub gene was verified by quantitative real time polymerase chain reaction. The transfection efficiency of BCL2 interacting protein like (BNIPL) was measured by western blot. Proliferation, migration, and invasion abilities were detected by Cell Counting Kit-8, wound-healing, and transwell assays, respectively. RESULTS: Total 96 overlapping DEGs were screened out from GSE143224 and GSE84957 datasets. Six hub genes (BNIPL, KRT4, IGFBP3, MMP10, MMP3, and TGFBI) were identified from PPI network. BNIPL was selected as the target gene. The receiver operating characteristic curves of BNIPL suggested that the false positive rate was 18.5% and the true positive rate was 81.5%, showing high predictive values for LC. The expression level of BNIPL was downregulated in TU212 and TU686 cells. Additionally, overexpression of BNIPL suppressed the proliferation, migration, and invasion of TU212 and TU686 cells. CONCLUSION: BNIPL is a novel gene signature involved in LC progression, which exerts an inhibitory effect on LC development. These findings provide a novel insight into the pathogenesis of LC.

A novel microRNA panel exhibited significant potential in evaluating the progression of laryngeal squamous cell carcinoma.

Background: Laryngeal squamous cell carcinoma (LSCC) is a common cancer of the head and neck in humans. The 5-years survival rate of patients with LSCC have declined in the past four decades. microRNAs (miRNAs) has been reported to be capable of predicting the prognosis outcomes of patients with different cancers. However, there are no reports on the usage of multi-miRNAs model as signature for the diagnosis or prognosis of LSCC. Methods: To establish the miRNAs expression-associated model for diagnosis, prognosis prediction and aided therapy of patients with LSCC, the present study enrolled 107 patients with LSCC in clinic and obtained 117 LSCC samples data from TCGA database for evaluation, respectively. Next generation sequencing (NGS), raw data processing, the least absolute shrinkage and selection operator algorithm, Cox regression analysis, construction of nomogram and cell function assays (including proliferation, migration and invasion assays) were sequentially performed. Results: There were massively dysregulated miRNAs in the LSCC compared to normal tissues. A six-miRNAs signature consists of miR-137-3p, miR-3934-5p, miR-1276, miR-129-5p, miR-7-5p and miR-105-5p was built for prognosis prediction of LSCC patients. The six-miRNAs signature is strongly associated with the poor overall survival (OS, p = 2.5e-05, HR: 4.30 [2.20-8.50]), progression free interval (PFI, p = 0.025, HR: 1.94 [1.08-3.46]) and disease specific survival (DSS, p = 1.1e-05, HR: 5.00 [2.50-10.00]). A nomogram for prediction of 2-, 3- and 5-years OS was also developed based on the six-miRNAs signature and clinical features. Furthermore, blocking the function of each of the six miRNAs inhibited proliferation, invasion and migration of LSCC cells. Conclusions: The performance of six-miRNAs signature described in the current study demonstrated remarkable potential for progression assessment of LSCC. Moreover, the six-miRNAs signature may serve as predictive tool for prognosis and therapeutic targets of LSCC in clinic.

The Clinical Features and Treatment Strategy of Parathyroid Cancer: A Retrospective Analysis.

Objective: To review the features and treatment of parathyroid cancer in our series. Explore the suitable extent of initial surgery and the effect of adjuvant radiotherapy in local recurrence. Methods: Seven cases of parathyroid cancer presented from 2014 to 2021. The presenting features, diagnosis, and treatment are presented. Results: Only two patients had multiple manifestations of hypercalcemia. Marked hypercalcemia, which was revealed to be an average of 13.9 mg/dl (range from 11.8 mg/dl to 15.8 mg/dl), was observed in four patients (57%). The others' serum calcium levels were in the normal range with an average of 9.9 mg/dl (range from 8.6 mg/dl to 10.8 mg/dl). All seven patients had hyperparathyroidism with an average of 733 pg/ml (range from 113 pg/ml to 3193 pg/ml). En bloc resection was performed in two patients with neighboring structure invasion, and four patients with complete tumor capsules underwent tumor resection with limited resection of the thyroid gland. Postoperative adjuvant radiotherapy appeared unsuccessful for local recurrence. Conclusion: High calcium, high PTH, parathyroid occupation by ultrasound, and intraoperative invasion should be considered to have the possibility of parathyroid cancer. Open surgery is recommended and protecting tumor integration is the elementary surgery principle. The initial surgical extent should be decided by the invasion of the tumor. When PC has a local recurrence, the debulking surgery and adjuvant radiotherapy are always fake.

Relapsing polychondritis causing breathlessness: Two case reports.

BACKGROUND: Relapsing polychondritis is a rare multisystem autoimmune disease that mainly involves systemic cartilage and proteoglycan-rich tissues. If the larynx and trachea are involved, the patient's condition deteriorates rapidly. When relapsing polychondritis becomes more advanced, the airways collapse and treatment is difficult, rendering a poor prognosis. Therefore, the diagnosis method, treatment strategy and prognosis of relapsing polychondritis with larynx and trachea involvement need to be elucidated to improve clinicians' awareness of the disease. CASE SUMMARY: A man and a woman were admitted because of breathlessness. Relapsing polychondritis was diagnosed after a series of accessory examinations. They were both treated with glucocorticoids and immunosuppressants, and underwent tracheotomy as their breathing difficulties could not be relieved by the medication. CONCLUSION: The two cases highlight the importance of the timely diagnosis, full evaluation and initiating individualized treatment of relapsing polychondritis with larynx and trachea involvement. Laryngoscopy, bronchoscopy and pathological examination are helpful in diagnosis of this disease.

[Effect of Biyanning Granules on local symptoms and immune function of chronic rhinosinusitis].

This study discusses the effect of Biyanning Granules on local symptoms and systemic immune function of patients with chronic rhinosinusitis with nasal polyps(CRSwNP) within the 6 months of treatment by glucocorticoid nasal spray after surgical treatment. To be specific, a total of 237 CRSwNP patients, treated in Otorhinolaryngology Head and Neck Surgery in Shanxi Bethune Hospital, were enrolled. All patients were treated by nasal endoscopy and classified into hormone group(Budesonide Nasal Spray after surgery), Chinese medicine group(Biyanning Granules after surgery), and combination group(Budesonide Nasal Spray+Biyanning Granules after surgery) with random number table method, 79 cases in each group, and the treatment lasted 3 months. The follow-up was performed from the day of discharge to 12 months after the surgery. The clinical effect was observed. The visual analogue scale(VAS) scores and sino-nasal outcome test-20(SNOT-20) scale scores were used to assess patient's subjective symptoms and quality of life. Lund-Kennedy endoscopic score(LKES), Japanese T&T olfactometry, and standard olfactory test were used to evaluate the objective curative effect on patients. The levels of interleukin(IL)-21, CD4~+CD25~+Foxp3~+Treg, and CD4~+Th17 in peripheral blood were analyzed. The incidence of complications, recurrence rate, and adverse reactions during treatment were also recorded. The total effective rate after treatment in the combination group was higher than that in the hormone group and Chinese medicine group(P<0.05). VAS scores and SNOT-20 scale scores were lower in the three groups after treatment than before treatment and lower in the combination group than in the other two groups(P<0.05). The improvement in LKES and T&T standard olfactometry test was better in the combination group than in the other two groups(P<0.05). Serum levels of IL-21 and CD4~+Th17 in the three groups were lower than before treatment. The levels in the combination group were lower than those in the other two groups and lower in the hormone group than in the Chinese medicine group(P<0.05). Serum CD4~+CD25~+Foxp3~+Treg level was higher in the three groups after treatment than before, higher in the combination group than in the other two groups, and higher in the Chinese medicine group than in the hormone group(P<0.05). During the treatment, no serious adverse reactions were observed. After treatment, the combination group showed no significant difference in the incidence and recurrence rate of complications from the hormone group and Chinese medicine group. In the treatment of CRSwNP with glucocorticoid, Biyanning Granules reduced the side effects of glucocorticoid and assisted glucocorticoid in alleviating the symptoms of patients. It significantly improved the curative effect, regulated immune imbalance, accele-rated the recovery of immune function, reduced the recurrence rate of inflammatory reaction, and improved the quality of life. The combination of Chinese and western treatment is more effective than glucocorticoid alone and warrants further clinical study in large sample size.

FSCN1 acts as a promising therapeutic target in the blockade of tumor cell motility: a review of its function, mechanism, and clinical significance.

Fascin actin-bundling protein 1 (FSCN1) is an actin-bundling protein that is capable of inducing membrane protrusions and plays critical roles in cell migration, motility, adhesion, and other cellular interactions. FSCN1 also plays a role in forming and stabilizing filopodia or microspikes, which assist during cell migration. Furthermore, FSCN1 is a downstream target of several microRNAs and participates in various biological processes, such as epithelial-to-mesenchymal transition and autophagy, which regulate the invasion and migration ability of cells in various cancers. Increased FSCN1 levels have been associated with enhanced migration and invasion of multiple cancers as well as poor patient prognosis. Promising results from in vitro experimental studies using docosahexaenoic acid (DHA) in breast cancer and recombinant porcine NK-lysin A in hepatocellular carcinoma have revealed that anticancer drugs targeting FSCN1 have significant potential clinical applications. This review discusses FSCN1 in terms of five aspects: structure and function, biological processes, regulatory mechanisms, clinical applications, and future prospects.

Biological roles and clinical significance of estrogen and androgen receptors in head and neck cancers.

Head and neck cancers (HNC) include malignant tumors that grow in and around the mouth, larynx, throat, sinuses, nose, and salivary glands. Accumulating evidence in malignancies suggests the aberrant expressions of the estrogen receptor (ER) and the androgen receptor (AR) in HNC, such as in laryngeal cancer and cancer of the salivary gland. Moreover, the signaling pathways involving these receptors that mediate tumorigenesis, proliferation, apoptosis, migration, and invasion have been elucidated. This review summarizes the roles of ER and AR with the putative signaling pathways involved in HNC. We also discuss the potential application of ER- and AR-related therapies in HNC. However, most of the mechanisms underlying AR and ER involvement in the development of HNC remain elusive and warrant further studies. A comprehensive understanding of the functional roles and mechanisms of action of AR and ER in HNC will facilitate the development of better therapeutic strategies for this disease. Overall, studies on AR and ER provide a promising potential for the diagnosis and treatment of HNC in the future.

Application of the CRISPR/Cas9-based gene editing technique in basic research, diagnosis, and therapy of cancer.

The 2020 Nobel Prize in Chemistry was awarded to Emmanuelle Charpentier and Jennifer Doudna for the development of the Clustered regularly interspaced short palindromic repeats/CRISPR-associated nuclease9 (CRISPR/Cas9) gene editing technology that provided new tools for precise gene editing. It is possible to target any genomic locus virtually using only a complex nuclease protein with short RNA as a site-specific endonuclease. Since cancer is caused by genomic changes in tumor cells, CRISPR/Cas9 can be used in the field of cancer research to edit genomes for exploration of the mechanisms of tumorigenesis and development. In recent years, the CRISPR/Cas9 system has been increasingly used in cancer research and treatment and remarkable results have been achieved. In this review, we introduced the mechanism and development of the CRISPR/Cas9-based gene editing system. Furthermore, we summarized current applications of this technique for basic research, diagnosis and therapy of cancer. Moreover, the potential applications of CRISPR/Cas9 in new emerging hotspots of oncology research were discussed, and the challenges and future directions were highlighted.

Regulatory role and mechanism of m6A RNA modification in human metabolic diseases.

Metabolic diseases caused by disorders in amino acids, glucose, lipid metabolism, and other metabolic risk factors show high incidences in young people, and current treatments are ineffective. N 6-methyladenosine (m6A) RNA modification is a post-transcriptional regulation of gene expression with several effects on physiological processes and biological functions. Recent studies report that m6A RNA modification is involved in various metabolic pathways and development of common metabolic diseases, making it a potential disease-specific therapeutic target. This review explores components, mechanisms, and research methods of m6A RNA modification. In addition, we summarize the progress of research on m6A RNA modification in metabolism-related human diseases, including diabetes, obesity, non-alcoholic fatty liver disease, osteoporosis, and cancer. Furthermore, opportunities and the challenges facing basic research and clinical application of m6A RNA modification in metabolism-related human diseases are discussed. This review is meant to enhance our understanding of the molecular mechanisms, research methods, and clinical significance of m6A RNA modification in metabolism-related human diseases.

VASN promotes proliferation of laryngeal cancer cells via YAP/TAZ.

PURPOSE: To explore whether vasorin protein (VASN) can affect the proliferation of laryngeal cancer cells through the regulation of yes-associated protein (YAP)/TAZ (transcriptional co-activator with PDZ binding motif), and then promote the development of laryngeal cancer. METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of VASN in laryngeal carcinoma tissues and different T-stage tumor patients, and the correlation between VASN expression and clinicopathological features was analyzed. The diagnostic value of VASN for laryngeal cancer was assessed by receiver operating characteristic (ROC) analysis. Kaplan-Meier method was used to plot the survival curves of patients with different VASN expression levels. After knocking down VASN in Hep-2 cells or in overexpressing VASN in TU212 cells, cell viability, proliferation ability and protein expression level of YAP/TAZ were detected by cell counting kit-8 (CCK-8), plate cloning assay and Western blot. Furthermore, YAP was overexpressed or knocked down simultaneously to evaluate its effect on the viability and proliferation ability of cells. RESULTS: The expression of VASN in laryngeal carcinoma was significantly higher than that in the normal control group, while, at the same time, the expression of VASN in the t3+t4 tumor patients was significantly higher than that in the t1+t2 tumors. We also found that the expression level of VASN was closely related to N stage, T stage, and lymph node metastasis, suggesting that VASN had a certain diagnostic value for laryngeal cancer. After knocking down VASN in cells, the cell viability, proliferative capacity and YAP/TAZ protein expression level decreased significantly. Besides, overexpressing YAP could reverse the inhibition of cell viability and proliferation ability caused by VASN knockdown. CONCLUSIONS: VASN can promote the development of laryngeal cancer by affecting the expression of YAP/TAZ.

Alterations of bacterial communities of vocal cord mucous membrane increases the risk for glottic laryngeal squamous cell carcinoma.

Bacteria are among the important factors that play a role in the balance of human health, and their relationship with some tumors has been well established. However, the association between bacteria colonizing the vocal cords and glottic laryngeal squamous cell carcinoma (GLSCC) remains unclear. Here, we investigated whether bacterial communities of the vocal cord mucous membrane play a role in the development of GLSCC. We collected tumor tissue and normal adjacent tissue (NAT) samples from 19 GLSCC patients, and the bacterial communities were compared with control samples (control) from 21 vocal cord polyps using 16S rRNA high-throughput pyrosequencing. We detected 41 phyla, 93 classes, 188 orders, 373 families, and 829 genera in the vocal cord mucous membrane. A comparison of the bacterial communities in the NAT samples showed higher α-diversity than in the tumor samples. In the tumor samples, seven groups of bacteria, i.e., the phylum Fusobacteria, the class Fusobacteriia, the order Fusobacteriales, the family Fusobacteriaceae, and the genera Fusobacterium, Alloprevotella, and Prevotella, were significantly enriched, as revealed by linear discriminant analysis coupled with effect size measurements (LEfSe). However, bacteria from the phylum Firmicutes were most significantly enriched in the vocal cord polyp tissues. These findings suggest alterations in the bacterial community structure of the vocal cord mucous membrane of GLSCC patients and that seven groups of bacteria are related to GLSCC, indicating that imbalances in bacterial communities increase the risk for the development of GLSCC.

Petroleum extract of Farfarae Flos alleviates nasal symptoms by regulating the Th1-Th2 cytokine balance in a mouse model of Allergic Rhinitis.

Farfarae Flos is a traditional Chinese medicine that has long been used to treat allergies. In this study, we aimed to investigate the effect of a petroleum extract of Farfarae Flos (PEFF) in a mouse model of allergic rhinitis (AR) and to explore the underlying molecular mechanisms of action. An animal model of AR was established by sensitization and challenge of BALB/c mice with ovalbumin (OVA). PEFF was administered intranasally and AR nasal symptoms were assessed on a semi-quantitative scale according to the frequencies of nose rubbing and sneezing and the degree of rhinorrhea. The mechanism of action of PEFF was evaluated by histological analysis of nasal mucosa architecture and inflammatory status; ELISA-based quantification of serum OVA-specific IgE, interferon-γ (IFN-γ), and interleukin-4 (IL-4) concentrations; and immunohistochemical and western blot analysis of T-bet and GATA3 protein expression in nasal mucosa and spleen tissues. The results showed intranasal administration of PEFF alleviated AR symptom scores and reduced both the infiltration of inflammatory cells and tissue damage in the nasal mucosa. PEFF significantly decreased serum concentrations of OVA-specific IgE (P<0.01) and IL-4 (P<0.05) and significantly increased IFN-γ (P<0.01). PEFF also upregulated the expression of T-bet protein (P<0.05) but downregulated GATA3 protein (P<0.05) in nasal mucosa and spleen tissues. In conclusion, PEFF effectively reduces AR nasal symptoms and serum IgE levels in a mouse model and may act by correcting the imbalance between Th1 and Th2 responses.

Targeting SKA3 suppresses the proliferation and chemoresistance of laryngeal squamous cell carcinoma via impairing PLK1-AKT axis-mediated glycolysis.

Spindle and kinetochore-associated complex subunit 3 (SKA3) is a well-known regulator of chromosome separation and cell division, which plays an important role in cell proliferation. However, the mechanism of SKA3 regulating tumor proliferation via reprogramming metabolism is unknown. Here, SKA3 is identified as an oncogene in laryngeal squamous cell carcinoma (LSCC), and high levels of SKA3 are closely associated with malignant progression and poor prognosis. In vitro and in vivo experiments demonstrate that SKA3 promotes LSCC cell proliferation and chemoresistance through a novel role of reprogramming glycolytic metabolism. Further studies reveal the downstream mechanisms of SKA3, which can bind and stabilize polo-like kinase 1 (PLK1) protein via suppressing ubiquitin-mediated degradation. The accumulation of PLK1 activates AKT and thus upregulates glycolytic enzymes HK2, PFKFB3, and PDK1, resulting in enhancement of glycolysis. Furthermore, our data reveal that phosphorylation at Thr360 of SKA3 is critical for its binding to PLK1 and the increase in glycolysis. Collectively, the novel oncogenic signal axis "SKA3-PLK1-AKT" plays a critical role in the glycolysis of LSCC. SKA3 may serve as a prognostic biomarker and therapeutic target, providing a potential strategy for proliferation inhibition and chemosensitization in tumors, especially for LSCC patients with PLK1 inhibitor resistance.

[Clinical characteristics and etiology of temporomandibular joint herniation into external ear canal].

Objective:To summarize the cases of temporomandibular joint herniation into external auditory canal found and treated in our hospital, to improve the understanding of oral and maxillofacial diseases and otological diseases, and to explore the potential long-term effects of local radiotherapy on temporomandibular joint function. Method:Analyzed the causes of temporomandibular joint herniation into external auditory canal comprehensively through combining history, clinical manifestations and imaging examination. Result:All otoscope results showed soft tissue mass in the deep anterior wall of the external auditory canal. The soft tissue mass moved inside and outside along with the opening and closing of the mouth. CT examination revealed obvious bone defects in the anterior wall of the ear canal. Conclusion:Delayed radiotherapy injury may be a inducing factor of temporomandibular joint herniation into external auditory canal. CT and MRI examination have guiding significance on the disease treatment selection. The specific signs found by otoscope can confirm the diagnosis.

Serum Exosomal miR-941 as a promising Oncogenic Biomarker for Laryngeal Squamous Cell Carcinoma.

At present, no blood-based biomarkers have been used in clinical practice for laryngeal squamous cell carcinoma (LSCC). Increasing evidence suggests that circulating exosomal microRNAs (miRNAs) may serve as potential diagnostic biomarkers for various cancers. This study aims to identify and evaluate serum exosomal miRNAs for LSCC diagnosis. The ExoQuick solution (EQ), which provides a high-yield and is a highly efficient exosome isolation method, was selected to isolate serum exosomes in the current study. In LSCC samples, exosome concentrations were higher than in healthy control (HC) samples. RNA-seq analysis identified a total of 1608 miRNAs, with 34 upregulated and 41 downregulated in LSCC samples relative to HC samples. Furthermore, qRT-PCR showed that miR-941 is significantly upregulated in LSCC serum exosomes, with this same trend seen in LSCC tissues and cells. Moreover, when examining miR-941 in cell lines, miR-941 overexpression promoted proliferation and invasion, while miR-941 knockdown inhibited cell proliferation and invasion. ROC curve analysis showed that miR-941 has an area under the curve (AUC) of 0.797 (95% CI = 0.676-0.918) for distinguishing LSCC patients from HCs. In conclusion, serum exosomal miR-941 may serve as a promising oncogenic biomarker for diagnosing LSCC, and has the potential as a therapeutic target.

Immune Microenvironment of Thyroid Cancer.

Thyroid cancer (TC) is a highly heterogeneous endocrine malignancy with an increased incidence in women than in men. Previous studies regarding the pathogenesis of TC focused on the pathological changes of the tumor cells while ignoring the importance of the mesenchymal cells in tumor microenvironment. However, more recently, the stable environment provided by the interaction of thyroid cancer cells with the peri-tumoral stroma has been widely studied. Studies have shown that components of an individual's immune system are closely related to the occurrence, invasion, and metastasis of TC, which may affect response to treatment and prognosis of the patients. This article presents a comprehensive review of the immune cells, secreted soluble mediators and immune checkpoints in the immune microenvironment, mechanisms that promoting TC cells immune evasion and existing immunotherapy strategies. Besides it provides new strategies for TC prognosis prediction and immunotherapy.
