Altered expression of GLS2 indicates a poor prognosis and correlates with clinicopathological features of oral squamous cell carcinoma. Int J Oral Maxillofac Surg 2024; 53:635-643. [PMID: 38342749 DOI: 10.1016/j.ijom.2024.01.011] [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: 09/08/2023] [Revised: 01/24/2024] [Accepted: 01/25/2024] [Indexed: 02/13/2024]
Abstract
Glutamine metabolism, governed by enzymes including glutaminase (GLS1 and GLS2), has a pivotal role in cancer progression. The objective of this study was to determine whether GLS2 transcription levels are associated with oral squamous cell carcinoma (OSCC) when compared to matched adjacent normal tissues. Primary tumour and adjacent normal tissues were collected from 51 OSCC patients, and GLS2 mRNA expression analysis was conducted using real-time qPCR. Additionally, The Cancer Genome Atlas-Head and Neck Squamous Cell Carcinoma (TCGA-HNSCC) dataset was utilized to examine GLS2 expression in relation to clinicopathological features, the prognosis, and tumour immune cell infiltration. A significantly reduced expression of GLS2 mRNA was found in the OSCC tissues when compared to the matched adjacent normal tissue samples (P < 0.001), which aligned with the results from the TCGA-HNSCC dataset and immunohistochemistry. Moreover, GLS2 mRNA expression was associated with clinicopathological features including tumour stage, grade, and human papillomavirus status (all P < 0.05), predicted a poorer prognosis (P = 0.024), and was correlated with tumour immune cell infiltration (all P < 0.05) in head and neck squamous cell carcinoma. Functional pathway analysis indicated its involvement in cell proliferation and metabolic cycles. GLS2 dysregulation is linked to oral cancer, suggesting its potential as a predictive prognostic marker for OSCC. Furthermore, targeting glutaminases via GLS2 may represent a promising therapeutic strategy for OSCC treatment.

Effects of Probiotics on Inflammatory Biomarkers and Its Associations With Cardiac Autonomic Function in Women With Arterial Hypertension: A Secondary Analysis of a Randomized Clinical Trial. Probiotics Antimicrob Proteins 2024:10.1007/s12602-024-10303-6. [PMID: 38842655 DOI: 10.1007/s12602-024-10303-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/31/2024] [Indexed: 06/07/2024]
Abstract
Preclinical evidence suggests that probiotic administration may exert an anti-inflammatory effect and reduce autonomic dysfunction and blood pressure. This study evaluated the effects of probiotic therapy on inflammatory biomarkers and characterized the correlations between inflammation and cardiac autonomic function in women with arterial hypertension. Women were randomized into probiotics (n = 20) or placebo (n = 20). The probiotic group received 109 CFU/day of Lactobacillus (L.) paracasei LPC-37, L. rhamnosus HN001, L. acidophilus NCFM, and Bifidobacterium lactis HN019, and the placebo group received polydextrose. Clinical, electrocardiogram, heart rate variability (HRV) analysis, and cytokine levels were assessed at baseline and after 8 weeks. Women who received probiotics for 8 weeks had increased serum levels of IL-17A (p = 0.02) and decreased INF-γ (p = 0.02) compared to baseline. Probiotic supplementation increased serum levels of IL-10 compared to the placebo group (p = 0.03). Probiotic or placebo administration did not change serum levels of TNFα and IL-6. Serum levels of IL-2 (p = 0.001, and p = 0.001) and IL-4 (p = 0.001, and p = 0.001) were reduced in women receiving placebo or probiotics, respectively. Correlations between HRV indices and inflammatory variables showed that INF-γ was positively correlated with heart rate (HR) and sympathetic HRV indices and negatively correlated with vagal HRV indices. IL-10 was negatively correlated with HR and sympathetic HRV indices. IL-6 was negatively correlated with parasympathetic HRV indices and positively correlated with SD2/SD1 ratio. Probiotic therapy has a discreet anti-inflammatory effect in hypertensive women, and pro-inflammatory cytokines were negatively correlated with vagal modulation and positively correlated with sympathetic modulation of HRV. The clinical trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with the identification RBR-9mj2dt.

Alteration of SERPINH1 is associated with elevated expression in head and neck squamous cell carcinomas and its clinicopathological significance. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2024; 125:101811. [PMID: 38432483 DOI: 10.1016/j.jormas.2024.101811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 02/28/2024] [Accepted: 02/29/2024] [Indexed: 03/05/2024]
Abstract
BACKGROUND/PURPOSE Head and neck squamous cell carcinoma (HNSCC) is the sixth leading cause of cancer-related death worldwide and contributes significantly to the burden of disease in South Asia, partially due to the lack of effective screening strategies. Identifying essential biomarkers is crucial for improved prognosis and treatment. This study investigates the potential of SERPINH1 as a prognostic marker in HNSCC, highlighting its significance amidst the molecular complexity. METHODS The Cancer Genome Atlas HNSCC cohort, comprised of 520 tumors and 44 normal tissues, was analyzed using cBioportal, UALCAN, and Protein atlas tools. Expression patterns, survival outcomes, and clinical correlations of SERPINH1 were evaluated. In-depth analyses involved oral squamous cell carcinoma (OSCC) patient samples, protein expression, and functional exploration using various in-silico tools. RESULTS SERPINH1 exhibited significant alteration and upregulation in HNSCC and OSCC, indicating its pan-cancer potential. Immunohistochemistry confirmed its overexpression in primary HNSCC tumors. Association analyses linked altered SERPINH1 levels with tumor stage, grade, metastasis, human papillomavirus (HPV) status, and patient prognosis. Functional analyses unveiled SERPINH1's involvement in critical cellular pathways and interactions with various proteins. CONCLUSION The significant alteration of SERPINH1 associated with upregulated expression in HNSCC and OSCC positions it as a promising diagnostic and prognostic marker. Further investigations are warranted to elucidate the underlying molecular mechanisms, paving the way for targeted therapeutic interventions and continued exploration of various malignancies.

Food Chem Toxicol 2024; 187:114599. [PMID: 38490352 DOI: 10.1016/j.fct.2024.114599] [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: 08/29/2023] [Revised: 03/08/2024] [Accepted: 03/12/2024] [Indexed: 03/17/2024]
Abstract
Aflatoxin B1 (AFB1), usually seriously contaminates in grain and oil foods or feed, displayed significant acute and chronic toxic effects in human and animal populations. However, little is known about the transgenerational toxic effects induced by a maternal AFB1 intake at a lower dose on offspring. In our study, only parental wild-type Caenorhabditis elegans was exposed to AFB1 (0-8 μg/ml) and the following three filial generations were grown on AFB1-free NGM. Results showed that the toxic effects of AFB1 on the growth (body length) and reproduction (brood size, generation time and morphology of gonad arm) can be transmitted through generations. Moreover, the levels of MMP and ATP were irreversibly inhibited in the filial generations. By using RNomics and molecular biology techniques, we found that steroid biosynthesis, phagosome, valine/leucine/isoleucine biosynthesis and oxidative phosphorylation (p < 0.05) were the core signaling pathways to exert the transgenerational toxic effects on nematodes. Also, notably increased histone methylation level at H3K36me3 was observed in the first generation. Taken together, our study demonstrated that AFB1 has notable transgenerational toxic effects, which were resulted from the complex regulatory network of various miRNAs, mRNAs and epigenetic modification in C. elegans.

Abstract
BACKGROUND/PURPOSE Smoking is a major contributor to global oral cancer cases, necessitating urgent intervention. FOXD1, involved in developmental processes and various cancers, shows promise as a prognostic marker in oral squamous cell carcinoma (OSCC). This study investigates the impact of waterpipe smoke condensate (WPSC) on OSCC, focusing on FOXD1 role in inducing epithelial-mesenchymal transition (EMT) and metastasis. METHODS The study involved using OSCC cells treated with WPSC to evaluate their proliferation, colony formation, gene expression, and protein levels. The researchers also explored the clinical relevance of their findings using online databases to analyze FOXD1 expression in cancer tissues and its correlation with clinicopathological features and patient survival. Additionally, in silico tools were employed for functional analysis, pathway enrichment, and network exploration. RESULTS The study found that WPSC increased the expression of FOXD1 in OSCC cells, which led to increased cell growth. The study also showed that FOXD1 plays a critical role in the EMT process induced by WPSC, as evidenced by changes in the expression of EMT-related genes and proteins. Clinical analysis revealed that FOXD1 was significantly associated with more aggressive tumor features and poorer prognosis in cancer patients. CONCLUSION The study highlights FOXD1 as a key player in OSCC pathogenesis and a potential prognostic marker and therapeutic target, particularly when influenced by WPSC exposure. Further research is needed to explore FOXD1 molecular mechanisms and clinical implications to enhance OSCC treatment strategies.

Odontology 2024:10.1007/s10266-024-00929-x. [PMID: 38575815 DOI: 10.1007/s10266-024-00929-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 03/13/2024] [Indexed: 04/06/2024]
Abstract
Abnormal expression of SEC14L2 has been implicated in many human cancers. However, the role of SEC14L2 in oral squamous cell carcinoma (OSCC) remains unclear. Therefore, this study aimed to evaluate the expression and prognostic roles of SEC14L2 in OSCC. OSCC tumors and adjacent non-tumors were collected from OSCC patients and used for SEC14L2 mRNA expression by quantitative reverse transcription PCR (RT-qPCR). Additionally, the expression of SEC14L2 was further analyzed using The Cancer Genome Atlas-Head Neck Squamous Cell Carcinoma (TCGA-HNSCC) dataset to identify its relationship with HNSCC clinical characteristics. The Kaplan-Meier plot was used to assess survival rates, and the Tumor Immune Estimation Resource (TIMER) database was used to examine the correlation between SEC14L2 expression and tumor immune cell infiltration. In silico tools also looked at SEC14L2 involvement in cancer pathways through its protein network. The mRNA and protein levels of SEC14L2 are notably higher in both OSCC and HNSCC tissues compared to adjacent normal tissues. Upregulation of SEC14L2 was associated with advanced tumor stages, grades, metastasis, HPV-negative, and TP53 mutations in cancer patients. In addition, the high expression of SEC14L2 was negatively correlated with the poor survival of cancer patients and the infiltration of diverse immune cells in cancer patients. According to the findings of this investigation, SEC14L2 is significantly elevated in OSCC/HNSCC patients and associated with a worse prognosis. More investigation and clinical studies are required to completely understand the therapeutic potential of SEC14L2 in HNSCC and convert these findings into better patient outcomes.
