Abstract
Food allergy is a global food safety problem with a growing prevalence. People in industrial regions are more susceptible to allergy, but the mechanisms behind this are not fully understood. In this study, the probiotic Lactobacillus casei Zhang (LcZ) was administered to allergic individuals and the impact on allergy-related factors were determined. LcZ alleviated allergenic responses, and there was a significant correlation between the intestinal isoleucine content and IgE concentration. Metagenomics results suggest that the metabolism of the gut microbiota is a source of isoleucine. In a mouse model of food allergy, a high isoleucine diet exacerbated allergic responses and increased the activity of allergenic dendritic cell. In a dendritic cell model, a protein array revealed that the mTOR/AKT pathway mediated the function of isoleucine, and molecular docking suggested that Sestrin2 could be the potential receptor. Overall, this study revealed the role of isoleucine in promoting food allergy, elucidated the underlying mechanisms, and suggested that a high intake of isoleucine could be a potential risk factor for food allergy.

A neutrophil extracellular traps-related classification predicts prognosis and response to immunotherapy in colon cancer. Sci Rep 2023; 13:19297. [PMID: 37935721 PMCID: PMC10630512 DOI: 10.1038/s41598-023-45558-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 10/20/2023] [Indexed: 11/09/2023] Open
Abstract
Neutrophil extracellular traps (NETs) have been categorized as a form of inflammatory cell death mode of neutrophils (NETosis) involved in natural immunity and the regulation of adaptive immunity. More and more studies revealed the ability of NETs to reshape the tumor immune microenvironment (TIME) by limiting antitumor effector cells, which may impair the efficacy of immunotherapy. To explore whether NETs-related genes make vital impacts on Colon carcinoma (COAD), we have carried out a systematic analysis and showed several findings in the present work. First, we obtained the patient's data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) dataset, aiming to detect two NETs-associated subtypes by consensus clustering. For the purpose of annotating the roles of NETs-related pathways, gene ontology enrichment analyses were adopted. Next, we constructed a 6 novel NETs-related genes score using the Least Absolute Shrinkage and Selection Operator (LASSO) Cox regression model. We found that the NETs risk score was notably upregulated in COAD patient samples, and its levels were notably correlated with tumor clinicopathological and immune traits. Then, according to NETs-associated molecular subtypes and the risk signature, this study compared immune cell infiltration calculated through the estimate, CIBERSORT, TIMER, ssGSEA algorithms, tumor immune dysfunction, as well as exclusion (TIDE). Furthermore, we confirm that MPO(myeloperoxidase) was significantly upregulated in COAD patient samples, and its levels were significantly linked to tumor malignancy and clinic outcome. Moreover, multiplex immunohistochemistry (mIHC) spatial analysis confirmed that MPO was closely related to Treg and PD-1 + Treg in spatial location which suggested MPO may paly an important role in TIME formation. Altogether, the obtained results indicated that a six NETs-related genes prognostic signature was conducive to estimating the prognosis and response of chemo-/immuno-therapy of COAD patients.

Gene 2023; 884:147686. [PMID: 37543219 DOI: 10.1016/j.gene.2023.147686] [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: 05/12/2023] [Revised: 07/05/2023] [Accepted: 08/01/2023] [Indexed: 08/07/2023]
Abstract
BACKGROUND Circular RNA (circRNA) is a novel noncoding RNA (ncRNA) that plays a critical role in various cancers. However, the clinical significance, biological function, and molecular mechanisms of circRNAs in laryngeal squamous cell carcinoma (LSCC) remain unclear. METHODS A circRNA array was performed to identify the differentially expressed circRNAs. In vitro and in vivo assays were proceeded to verify the biological function of circCDK1 in LSCC. RNA pulldown assays and RNA immunoprecipitation (RIP) were used to confirm the binding between circCDK1 and insulin-like growth factor 2 mRNA binding protein 2(IGF2BP2). The MeRIP assay was then used to identified the N6-methyladenisine (m6A) methylation of calcineurin like phosphatase domain containing1 (CPPED1). RESULTS Hsa_circ_0005774 (circCDK1) was found upregulated in LSCC tissues compared to adjacent normal tissues. The level of circCDK1 was positively correlated with poor prognosisof LSCC patients. In vitro and in vivo, circCDK1 promoted migration and invasion of LSCC cells. Mechanistically, eukaryotic translation initiation factor4A3(EIF4A3) induced biogenesis of circCDK1 by binding to its flanking. By competitively binding to IGF2BP2, circCDK1 blocked the m6A modification of CPPED1 in IGF2BP2-dependent manner. Moreover, the circCDK1-mediated decrease of CPPED1 activated the PI3K/AKT signal pathway to facilitate progression of LSCC. CONCLUSIONS Our findings demonstrated that EIF4A3-induced upregulation of circCDK1 promoted LSCC metastasis via EIF4A3-circCDK1-IGF2BP2-CPPED1 to activate PI3K-AKT signal pathway. CircCDK1 might serve as a new diagnostic and prognostic marker or potential therapeutic target for LSCC.

Abstract
A high number of cancer-related deaths (up to 90) are due to metastasis and simple definition of metastasis is new colony formation of tumor cells in a secondary site. In tumor cells, epithelial-mesenchymal transition (EMT) stimulates metastasis and invasion, and it is a common characteristic of malignant tumors. Prostate cancer, bladder cancer and renal cancer are three main types of urological tumors that their malignant and aggressive behaviors are due to abnormal proliferation and metastasis. EMT has been well-documented as a mechanism for promoting invasion of tumor cells and in the current review, a special attention is directed towards understanding role of EMT in malignancy, metastasis and therapy response of urological cancers. The invasion and metastatic characteristics of urological tumors enhance due to EMT induction and this is essential for ensuring survival and ability in developing new colonies in neighboring and distant tissues and organs. When EMT induction occurs, malignant behavior of tumor cells enhances and their tend in developing therapy resistance especially chemoresistance promotes that is one of the underlying reasons for therapy failure and patient death. The lncRNAs, microRNAs, eIF5A2, Notch-4 and hypoxia are among common modulators of EMT mechanism in urological tumors. Moreover, anti-tumor compounds such as metformin can be utilized in suppressing malignancy of urological tumors. Besides, genes and epigenetic factors modulating EMT mechanism can be therapeutically targeted for interfering malignancy of urological tumors. Nanomaterials are new emerging agents in urological cancer therapy that they can improve potential of current therapeutics by their targeted delivery to tumor site. The important hallmarks of urological cancers including growth, invasion and angiogenesis can be suppressed by cargo-loaded nanomaterials. Moreover, nanomaterials can improve chemotherapy potential in urological cancer elimination and by providing phototherapy, they mediate synergistic tumor suppression. The clinical application depends on development of biocompatible nanomaterials.

Abstract
This study aims to explore the role of SKA1 in cancer diagnosis and prognosis and to investigate the mechanism by which SKA1 affects the malignant behaviors of ovarian cancer. Herein, we analyzed the oncogenic role of SKA1 at pan-cancer level by multiple informatics databases and verified the analysis by in vitro experiments. As a result, SKA1 was upregulated across cancers and was related to poor clinical outcome and immune infiltration. Specifically, the constructed nomogram showed superior performance in predicting the prognosis of epithelial ovarian cancer patients. Furthermore, the in vitro experiments revealed that silencing SKA1 significantly inhibited the proliferation, migratory ability and enhanced the cisplatin sensitivity of ovarian cancer cells. Therefore, we explored the oncogenic and potential therapeutic role of SKA1 across cancers through multiple bioinformatic analysis and revealed that SKA1 may promote ovarian cancer progression and chemoresistance to cisplatin by activating the AKT-FOXO3a signaling pathway.

Differential ion mobility mass spectrometry in immunopeptidomics identifies neoantigens carrying colorectal cancer driver mutations. Commun Biol 2022; 5:831.

Abstract
Understanding the properties of human leukocyte antigen (HLA) peptides (immunopeptides) is essential for precision cancer medicine, while the direct identification of immunopeptides from small biopsies of clinical tissues by mass spectrometry (MS) is still confronted with technical challenges. Here, to overcome these hindrances, high-field asymmetric waveform ion mobility spectrometry (FAIMS) is introduced to conduct differential ion mobility (DIM)-MS by seamless gas-phase fractionation optimal for scarce samples. By established DIM-MS for immunopeptidomics analysis, on average, 42.9 mg of normal and tumor colorectal tissues from identical patients (n = 17) were analyzed, and on average 4921 immunopeptides were identified. Among these 44,815 unique immunopeptides, two neoantigens, KRAS-G12V and CPPED1-R228Q, were identified. These neoantigens were confirmed by synthetic peptides through targeted MS in parallel reaction monitoring (PRM) mode. Comparison of the tissue-based personal immunopeptidome revealed tumor-specific processing of immunopeptides. Since the direct identification of neoantigens from tumor tissues suggested that more potential neoantigens have yet to be identified, we screened cell lines with known oncogenic KRAS mutations and identified 2 more neoantigens that carry KRAS-G12V. These results indicated that the established FAIMS-assisted DIM-MS is effective in the identification of immunopeptides and potential recurrent neoantigens directly from scarce samples such as clinical tissues.

Abstract
Background Epidemiological studies have reported various results regarding whether FOXO3A is related to various carcinomas. However, the prognostic significance of FOXO3A in upper tract urothelial carcinoma (UTUC) remains unclear. The purpose of this study was to validate the correlation between FOXO3A expression and oncological outcomes in UTUC. Methods The expression levels of FOXO3A in 107 UTUC patients were examined by immunohistochemistry (IHC). We examined the prognostic role of FOXO3A by using the Cox proportional hazard model. Results The results indicated that FOXO3A expression was notably decreased in UTUC tissue compared with control tissue. Decreased expression of FOXO3A was also related to advanced pathologic stage (P = 0.026), lymph node metastasis (P = 0.040), lymphovascular invasion (P < 0.001), and adjuvant therapy (P = 0.048). In addition, UTUC patients with low FOXO3A expression had a significantly shorter survival time, including both overall survival (OS) [hazard ratio (HR) 2.382, P = 0.004] and recurrence-free survival (RFS) (HR 2.385, P = 0.004), than those with high expression. Multivariate analyses showed that FOXO3A was a significant predictor for OS (HR 2.145, P = 0.014) and RFS (HR 2.227, P = 0.010) in UTUC patients. Conclusion Our results indicate that FOXO3A may be involved in the recurrence of UTUC and that it has certain clinical value in the therapeutic targeting and prognostic evaluation of UTUC.

Abstract
Desloratadine, a potent antagonist for human histamine H1 receptor, has been revealed to exhibit antihistaminic activity and anti-inflammatory activity. However, it is not yet known whether desloratadine has any effect on the biological behaviors of tumor cells. In this study, we aimed to investigate the effects of desloratadine on cell growth and invasion in bladder cancer EJ and SW780 cells in vitro. We observed that desloratadine inhibited cell viability of EJ and SW780 cells in a dose- and time-dependent manner. Desloratadine treatment was also revealed to suppress colony-formation ability and induce cell cycle arrest at G1 phase in EJ cells. Desloratadine promoted cell apoptosis via modulating the expression of Bcl-2, Bax, cleaved caspase 3, and cleaved caspase 9 in EJ and SW780 cells. Western blot resulted showed that desloratadine also impaired the expression of autophagy-related proteins, such as Beclin 1, P62, and LC3I/II in EJ and SW780 cells; while autophagy inhibitor LY294002 reversed the effects of desloratadine on these proteins. Moreover, desloratadine remarkably attenuated cell migration and invasion. Furthermore, we illustrated that desloratadine downregulated the expression of N-cadherin, Vimentin, Snail1, and Snail2, while upregulated the expression of E-cadherin in EJ and SW780 cells in vitro. The level of interleukin 6 was reduced in desloratadine-treated cells, while upregulation of interleukin 6 significantly abolished the anticancer activity of desloratadine in cell invasion and Bcl-2, Bax, Beclin1, LC3-I/II, N-cadherin, and E-cadherin expression in EJ cells. Taken together, our data suggest a potential anticancer activity of desloratadine on cell growth and invasion for bladder cancer, which may be mediated by diminishing the epithelial-to-mesenchymal transition and interleukin 6.

Abstract
MicroRNAs (miRNAs) are important regulators of gene expression, and their expression is associated with many physiological conditions. Here, we investigated potential associations between expression levels of miRNAs in human placenta and the onset of spontaneous term birth. Using RNA sequencing, we identified 54 miRNAs differentially expressed during spontaneous term labor compared to elective term births. Expression levels of 23 miRNAs were upregulated, whereas 31 were downregulated at least 1.5-fold. The upregulated miRNA miR-371a-5p putatively targets CPPED1, expression of which decreases during spontaneous birth. We used a luciferase reporter–based assay to test whether a miR-371a-5p mimic affected translation when it bound to the 3′ untranslated region of CPPED1. In this setting, the miR-371a-5p mimic resulted in lower luciferase activity, which suggests that miR-371a-5p regulates levels of CPPED1. In conclusion, inversely correlated levels of miR-371a-5p and CPPED1 suggest a role for both in spontaneous delivery.

Abstract
Background Current clinical treatments for osteosarcoma are limited by disease recurrence and primary or secondary chemoresistance. Cancer stem-like cells have been proposed to facilitate the initiation, progression, recurrence and chemoresistance of osteosarcoma. Furthermore, previous studies have reported that IL-6-STAT3 pathway is overexpressed in various types of cancer and contributes to cell proliferation, apoptosis, invasion/migration, chemoresistance and modulation of stemness features. Aim To examined the effect of cinobufagin on cancer progression and modulation of stemness features in osteosarcoma, and investigated the molecular mechanisms underlying such effects. Methods Human osteosarcoma cell lines U2OS/MG-63 were recruited in this study. Cell proliferation, migration, and invasion were determined by MTT assay, colony formation assay,wound healing assay, and cell invasion assay respectively. Its effect on stemness was assessed by flow cytometry and mammosphere formation. The protein expression levels of related proteins were detected by Western blot. The xenograft model, immunofluorescence staining and immunohistochemistry were used to determine the effect of cinobufagin on tumorigenicity in vivo experiment. Results We found that cinobufagin suppressed the viability of U2OS/MG-63 spheroids/parent cells in a time-and dose-dependent manner. Notably, cinobufagin had no effect on the viability of hFOB 1.19 cells. Moreover, cinobufagin induced apoptosis, increased the width of wounds, reduced invasive osteosarcoma spheroids/parent cell numbers and reduced EMT phenotype and OPN levels in U2OS/MG-63 spheroids as well as U2OS/MG-63 parent cells lines. Noticeablely, we found that OPN levels were higher in spheroids group than that in parent cells. In addition, cinobufagin ameliorated the proportion of CD133-positive cells, the size of spheroids and Nanog, Sox-2 and Oct3/4 protein levels. Our in vivo experiments showed that cinobufagin consistently reduced tumor volume,the expressions of OPN, Sox-2, Oct3/4, Nanog and p-STAT3 by the immuno histochemistry staining as well as CD133 expression in tumor tissues by immunofluorescence analysis. From a mechanistic point of view, cinobufagin was shown to inhibit IL-6-OPN-STAT3 signaling pathway. Exogenous IL-6/OE-OPN/overexpression STAT3 attenuated the induction of cinobufagin-mediated apoptosis and the suppression of stemness properties respectively. Conclusion Collectively, our data demonstrated that cinobufagin inhibited the viability and tumorigenesis capability of osteosarcoma cells by blocking IL-6- OPN-STAT3 signaling pathway. Cinobufagin may therefore represent a promising therapeutic agent for osteosarcoma management. ![]()
