[PMID: 39550325 DOI: 10.1016/j.jvoice.2024.10.003] [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: 08/18/2024] [Revised: 10/02/2024] [Accepted: 10/03/2024] [Indexed: 11/18/2024]
Abstract
OBJECTIVE We assessed the expression of glucose transporter (GLUT)-1 and hexokinase (HK)-Ⅱ in vocal cord leukoplakia (VCL) and investigated its clinical significance. METHODS We collected 127 archival pathological specimens from patients with VCL, 29 from vocal cord polyps, and 31 with laryngeal carcinoma at our hospital between December 2018 and December 2022. GLUT-1 and HK-II expression was detected using immunohistochemistry. RESULTS Significant differences were observed between the VCL and vocal cord polyp groups according to sex (P < 0.0001), smoking status (P = 0.001), and alcohol consumption (P = 0.007). GLUT-1 expression was observed in 36.2%, 20.7%, and 90.3% of patients with VCL, vocal cord polyps, and laryngeal carcinoma, respectively. GLUT-1 was highly expressed in severe dysplasia or carcinoma in situ (CIS) compared with vocal cord polyps (P < 0.001). GLUT-1 expression was lower in the VCL group than in the laryngeal carcinoma group (P < 0.001). HK-II expression was observed in 42.5%, 34.5%, and 80.6% of patients with VCL, vocal cord polyps, and laryngeal carcinoma, respectively. HK-II expression was significantly higher in severe dysplasia or CIS compared with vocal cord polyps (P = 0.004). HK-II expression was lower in the VCL group than in the laryngeal carcinoma group (P < 0.001). Both GLUT-1 expression (P < 0.001) and HK-II expression (P = 0.03) increased significantly with the degree of dysplasia. A significant correlation was observed between GLUT-1 and HK-II expression (r = 0.313, P < 0.001). CONCLUSION GLUT-1 and HK-II are significantly overexpressed in VCL patients. In VCL patients, GLUT-1 and HK-II expression levels increase proportionally with the degree of dysplasia.

Identification and Validation of the Anoikis-Related Gene Signature as a Novel Prognostic Model for Cervical Squamous Cell Carcinoma, Endocervical Adenocarcinoma, and Revelation Immune Infiltration. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:358. [PMID: 36837559 PMCID: PMC9958637 DOI: 10.3390/medicina59020358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 02/07/2023] [Accepted: 02/08/2023] [Indexed: 02/16/2023]
Abstract
Background and Objectives: Cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) are malignant disorders with adverse prognoses for advanced patients. Anoikis, which is involved in tumor metastasis, facilitates the survival and separation of tumor cells from their initial site. Unfortunately, it is rarely studied, and in the literature, studies have only addressed the prognosis character of anoikis for patients with CESC. Materials and Methods: We utilized anoikis-related genes (ANRGs) to construct a prognostic signature in CESC patients that were selected from the Genecards and Harmonizome portals. Furthermore, we revealed the underlying clinical value of this signature for clinical maneuvers by providing clinical specialists with an innovative nomogram on the basis of ANRGs. Finally, we investigated the immune microenvironment and drug sensitivity in different risk groups. Results: We screened six genes from fifty-eight anoikis-related differentially expressed genes in the TCGA-CESC cohort, and we constructed a prognostic signature. Then, we built a nomogram combined with CESC clinicopathological traits and risk scores, which demonstrated that this model may improve the prognosis of CESC patients in clinical therapy. Next, the prognostic risk scores were confirmed to be an independent prognostic indicator. Additionally, we programmed a series of analyses, which included immune infiltration analysis, therapy-related analysis, and GSVA enrichment analysis, to identify the functions and mechanisms of the prognostic models during the progression of cancer in CESC patients. Finally, we performed quantitative reverse transcription polymerase chain reaction (qRT-PCR) to verify the six ANRGs. Conclusions: The present discovery verified that the predictive 6-anoikis-related gene (6-ANRG) signature and nomogram serve as imperative factors that might notably impact a CESC patient's prognosis, and they may be able to provide new clinical evidence to assume the role of underlying biological biomarkers and thus become indispensable indicators for prospective diagnoses and advancing therapy.

Giri P, Camarillo IG, Sundararajan R. Enhancement of reactive oxygen species production in triple negative breast cancer cells treated with electric pulses and resveratrol. EXPLORATION OF TARGETED ANTI-TUMOR THERAPY 2023; 4:42-56. [PMID: 36937321 PMCID: PMC10017187 DOI: 10.37349/etat.2023.00122] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Accepted: 12/28/2022] [Indexed: 03/04/2023] Open
Abstract
Aim Triple negative breast cancer (TNBC) is difficult to treat since it lacks all the three most commonly targeted hormone receptors. Patients afflicted with TNBC are treated with platinum core chemotherapeutics, such as cisplatin. Despite the initial effective anticancer effects of cisplatin, TNBC attenuates its effect and develops resistance eventually, which results in tumor reoccurrence. Hence, there is a critical demand for effective, alternative, and natural ways to treat TNBC. Towards this, a promising technique for inhibiting TNBC cell proliferation involves promoting the production of reactive oxygen species (ROS), which triggers pro-apoptotic caspases 9 and 3. Resveratrol (RESV), an active bio compound found in naturally available fruits, such as grapes, is utilized in this research for that. In addition, electrochemotherapy (ECT), which involves the application of electrical pulses (EP), was utilized to enhance the uptake of RESV. Methods MDA-MB-231, human TNBC cells were treated with/out RESV, and eight 600-1,000 V/cm, 100 μs pulses at 1 Hz. The cells were characterized by using various assays, including viability assay, and ROS assay. Results A TNBC cell viability of as low as 20% was obtained at 24 h (it was 13% at 60 h), demonstrating the potential of this novel treatment. ROS production was the highest in the combination of EP at 1,000 V/cm along with RESV at 100 μmol/L. Conclusions Results indicate that RESV has the potential as an anti-TNBC agent and that EP + RESV can significantly enhance the cell death to reduce MDA-MB-231 cell viability by increasing ROS production and triggering apoptosis.

Abstract
Background The aim of this study was to investigate the relationship between multiple metabolism parameters derived from FDG and tumor TNM stages as well as tumor metastasis-associated protein of GLUT-1 and MACC1 in colorectal carcinoma (CRC). Methods Thirty-eight patients (24 males and 14 females) with primary CRC confirmed by elective surgery pathological, who also accepted 18F-FDG PET/CT scans during 2017 to 2019 were included in this study. The tumor classification of T, N and M is explained by the 7th American Joint Committee on Cancer (AJCC). 18F-FDG parameters of SUVmax, SUVmean, TLG and MTV were measured by drawing a region of interest on the primary lesions. The expression of GLUT-1 and MACC1 was quantified by immunohistochemical, and the correlation between metabolism parameters and tumor biomarkers were analyzed. Results According to our analysis, the 18F-FDG parameters of SUVmean was significantly correlated with tumor M status (P = 0.000) of primary CRC. The primary tumor lesion with higher SUVmax, TLG and MTV values prone to a high-T status (P = 0.002, 0.002 and 0.001, respectively). The high expression of GLUT-1/MACC1 weas more frequently involved with T3–4 stage and was poorly differentiated in CRC patients. Multivariate analysis found that the expression of GLUT-1 protein was correlated with SUVmax and MTV (R2 = 0.42, P = 0.013 and 0.004, respectively), moreover, the expression of MACC1 protein was correlated with TLG (R2 = 0.372, P = 0.000). Conclusion Glucose metabolism parameters derived from FDG provides a noninvasive assessment of M status and T status in CRC patients. The expression of GLUT-1 and MACC1 was associated with 18F-FDG uptake in CRC patients.

Abstract
Cancer cells undergo metabolic changes that support their malignant growth. These changes are often associated with increased expression of the rate-limiting glycolytic enzyme hexokinase 2. Hexokinase 2 is an enzyme that catalyzes the conversion of glucose to glucose-6-phosphate. In this study, we utilized Gene Expression Profiling Interactive Analysis (GEPIA) database analysis and clinical sample analysis to find that hexokinase 2 was highly expressed in cervical cancer. Furthermore, we found that high hexokinase 2 expression in cervical cancer demonstrated a positive correlation with tumor size (P = .009696), pathological grade (P = .028551), and prognosis (P = .00069) but not with age (P = .956201) or lymph node metastasis (P = .131379). At the cellular level, we knocked down the expression of hexokinase 2 in the human cervical cancer cell line SiHa. The results demonstrated that knockdown of hexokinase 2 inhibited the proliferation and migration of SiHa cells and promoted cell apoptosis. During this process, knockdown of hexokinase 2 inhibited phosphorylation of AKT and mammalian target of rapamycin and promoted p53 expression. At the same time, overexpression of human papillomavirus 18 oncogenes E6 and E7 significantly promoted the expression of hexokinase 2. Most importantly, we discovered a novel upstream regulatory microRNA for hexokinase 2: miR-9-5p. Luciferase reporter assays and Western blot assays demonstrated that hexokinase 2 expression was inhibited by miR-9-5p by directly binding its 3′-untranslated region in SiHa cells. Next, we determined that miR-9-5p could suppress the proliferation and migration of SiHa cells and induce apoptosis. In conclusion, we found that hexokinase 2 serves a carcinogenic role in cervical cancer through the miR-9-5p/hexokinase 2/AKT pathway, which serves as the basis for potential therapeutic targets and prognostic indicators.

Abstract
PURPOSE Malignant cells exhibit increased rates of aerobic glycolysis. Here, we tested whether the accumulation of fluoro-deoxyglucose-6-phosphate (FDG6P) in ovarian cancers of differential malignancy reflects inversely correlated elevations of hexokinase (HK) and glucose-6-phosphatase (G6Pase) activities. PROCEDURES Twenty-nine women with suspected ovarian cancer had positron emission tomography (PET) prior to surgery. From fresh-frozen tissue, we determined the activities of HK and G6Pase, and from the PET images, we determined the tumor maximum standardized uptake value (SUVmax) of 2-deoxy-2-[18F]fluoro-D-glucose. RESULTS The SUVmax of malignant lesions significantly exceeded the SUVmax of benign (p < 0.005) and borderline lesions (p < 0.0005) that did not differ significantly. We found no significant correlation between measured HK or G6Pase activities and histological tumor type or SUVmax except that G6Pase activities were higher in malignant than borderline lesions (p < 0.05). Measured HK and G6Pase activities correlated inversely (p < 0.05). The slopes from the regression lines of the three correlations yielded positively correlated abscissa and ordinate intercepts, designated HKmax and G6Pasemax, respectively (r = 0.67, p < 0.0001). The positive correlations between the abscissa and ordinate intercepts with SUVmax had regression coefficients of r = 0.44, p < 0.05; and r = 0.39, p < 0.05, respectively. CONCLUSIONS The results distinguished two ovarian cancer phenotypes, one with elevated HK activity and low G6Pase activity, and another with the opposite characteristics.

Abstract
Positron Emission Tomography (PET) is a functional imaging modality widely used in clinical oncology. Over the years the sensitivity and specificity of PET has improved with the advent of specific radiotracers, increased technical accuracy of PET scanners and incremental experience of Radiologists. However, significant limitations exist—most notably false positives and false negatives. Additionally, the accuracy of PET varies between cancer types and in some cancers, is no longer considered a standard imaging modality. This review considers the relative influence of macroscopic tumour features such as size and morphology on 2-Deoxy-2-[18F]fluoroglucose ([18F]FDG) uptake by tumours which, though well described in the literature, lacks a comprehensive assessment of biomolecular features which may influence [18F]FDG uptake. The review aims to discuss the potential influence of individual molecular markers of glucose transport, glycolysis, hypoxia and angiogenesis in addition to the relationships between these key cellular processes and their influence on [18F]FDG uptake. Finally, the potential role for biomolecular profiling of individual tumours to predict positivity on PET imaging is discussed to enhance accuracy and clinical utility.

Abstract
Purpose Non-small-cell lung cancer (NSCLC) is the one of the most common malignancies worldwide, and occurs at a higher frequency in male individuals. Little is known about the role of the long intergenic noncoding RNA for kinase activation (LINK-A) in NSCLC, so in the present study we assessed its potential role on cell proliferation in NSCLC. Methods Expression levels of LINK-A in NSCLC tissues and cell lines were detected by quantitative reverse-transcription polymerase chain reaction. LINK-A was knocked down and overexpressed separately in A549 cells and NCI-H1299 cells. The effect of LINK-A expression on cell proliferation was determined by MTT assay. The correlation between LINK-A and hexokinase II (HKII) expression was investigated by Western blot and HKII Activity Assay. Glucose consumption and lactate production assay were used to investigate the aerobic glycolysis in NSCLC cells. The effect of LINK-A in vivo was determined by xenograft assay. Results LINK-A expression levels were increased in NSCLC tissues compared with normal tissues. Moreover, LINK-A expression was positively correlated with NSCLC clinicopathological characteristics and survival rate, while knockdown of LINK-A reduced NSCLC cell proliferation. LINK-A expression was also positively correlated with HKII, and NSCLC cells with low LINK-A expression were found to have significantly reduced HKII protein expression, accompanied by a reduction in enzyme activity levels. Both in vitro and in vivo experiments showed that LINK-A expression affected glucose consumption and lactate production through regulation of HKII expression. Conclusion These data suggest that the functions of LINK-A in NSCLC might play a key role in tumor progression and that LINK-A could be a promising predictive biomarker and potential therapeutic target for NSCLC.

Abstract
BACKGROUND Anaerobic glycolysis is an important physiological process of all cancer cells. Butein has been reported to demonstrate substantial antitumor activities in various cancers. However, the effect of butein on tumor glycolysis remains unclear. In this study, the effect of butein on tumor glycolysis and the underlying mechanism were investigated in hepatocellular carcinoma (HCC). MATERIAL AND METHODS Cell proliferation assay and anchorage-independent growth assay were carried out to evaluate the antitumor activities of butein in vitro. The effect of butein on tumor glycolysis was determined by examining the changes in glucose uptake and lactate production. Hexokinase-2 (HK-2) expression in HCC cells upon butein treatment was analyzed by Western blotting. The activity of butein on EGFR signaling pathway was studied and its potency in EGFR exogenous overexpression cells was investigated. RESULTS After butein treatment, HCC cell proliferation was significantly inhibited (91.4% in Hep3B and 88.2% in Huh-7 at 80 μM, p<0.001). Moreover, the number of colonies formed in the agar was substantially decreased (93.8% in Hep3B and 72.3% in Huh-7 at 80 μM, p<0.001). With the suppression of HK-2 expression, glucose consumption in Hep3B and Huh-7 cells decreased by 48.4% and 56.3%, respectively (p<0.01), and the lactate production also was reduced accordingly (39.5% in Hep3B and 48.6% in Huh-7, p<0.01). Mechanism investigations demonstrated that butein dose-dependently blocked the activation of the EGFR signaling pathway in HCC cells. In EGFR exogenous overexpression cells, the glycolysis suppression exerted by butein was substantially attenuated. CONCLUSIONS Butein has a substantial inhibitory effect on tumor glycolysis in HCC cells, and the glycolysis suppression exerted by butein is closely related to its effect on the EGFR signaling pathway.

Abstract
The objective of the present study was to investigate the prognostic value of 18F-fluoro-2-deoxy-D-glucose (FDG) uptake by primary tumors on positron emission tomography/computed tomography (PET/CT) in surgically resectable cervical cancer. A total of 59 patients with stage IA2-IIB cervical cancer who underwent preoperative FDG-PET/CT, followed by radical hysterectomy and lymphadenectomy, were included in the study. The maximum standardized uptake value (SUVmax) of the primary tumor was measured, and the association between the SUVmax and clinicopathological factors or patient outcomes was analyzed. The SUVmax was significantly higher in patients with an advanced stage, lymph node metastasis, lymph-vascular space involvement and large tumors. The overall survival (OS) and progression-free survival (PFS) of patients with a high SUVmax were significantly lower compared with patients with a low SUVmax, using an optimal cut-off value of 7.36 for OS and 5.59 for PFS obtained from receiver operating characteristic curve analysis. Similarly, OS and PFS in patients with a high SUVmax were significantly lower in 39 patients with stage IB using a cut-off value of 7.90 and 6.69 for OS and PFS, respectively. Finally, multivariate analyses showed that the SUVmax of the primary tumor was an independent prognostic factor for impaired PFS in all patients and those with stage IB alone. These findings demonstrated that a high SUVmax on preoperative PET/CT was correlated with unfavorable clinical outcomes in patients receiving radical hysterectomy, suggesting that the SUVmax of the primary tumor may be a prognostic indicator for surgically-treated, early-stage invasive cervical cancer.

Abstract
Usually, benign tumors are not associated with an increased F-18 fluorodeoxyglucose (F-18 FDG) uptake on positron emission tomography (PET), although some exceptions have been reported in adrenal neoplasms. We present a rare case of adrenocortical oncocytoma associated with markedly increased FDG uptake, demonstrating a maximum standardized uptake value of 46.8. Histological examination demonstrated diffuse proliferation of tumor cells with eosinophilic and granular cytoplasm that were diffusely immunopositive for mitochondria and glucose transport protein 1, with focal and weak immunopositivity for 3β-hydroxysteroid dehydrogenase. Ultrastructural examination also revealed abundant mitochondria in the tumor cells. The tumor was diagnosed as adrenocortical oncocytoma and was considered benign according to Lin-Weiss-Bisceglia criteria. Diagnosis of adrenocortical oncocytoma can pose difficulties during both preoperative radiological and postoperative histopathological investigations.

Abstract
The mechanisms underlying cancer radioresistance remain unclear. Several studies have found that increased glucose transporter‑1 (GLUT‑1) expression is associated with radioresistance. Recently, the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway was reported to be involved in the control of GLUT‑1 trafficking and activity. Activation of the PI3K/Akt pathway may itself be associated with cancer radioresistance. Thus, increasing attention has been devoted to the effects of modifying the expression of GLUT‑1 and the PI3K/Akt pathway on the increase in the radiosensitivity of cancer cells. This review discusses the importance of the association between elevated expression of GLUT‑1 and activation of the PI3K/Akt pathway in the development of radioresistance in cancer.

Glucose metabolism gene expression patterns and tumor uptake of ¹⁸F-fluorodeoxyglucose after radiation treatment. Int J Radiat Oncol Biol Phys 2014; 90:620-7. [PMID: 25304950 DOI: 10.1016/j.ijrobp.2014.06.062] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2014] [Revised: 05/21/2014] [Accepted: 06/23/2014] [Indexed: 11/21/2022]
Abstract
PURPOSE To investigate whether radiation treatment influences the expression of glucose metabolism genes and compromises the potential use of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) as a tool to monitor the early response of head and neck cancer xenografts to radiation therapy (RT). METHODS AND MATERIALS Low passage head and neck squamous cancer cells (UT14) were injected to the flanks of female nu/nu mice to generate xenografts. After tumors reached a size of 500 mm(3) they were treated with either sham RT or 15 Gy in 1 fraction. At different time points, days 3, 9, and 16 for controls and days 4, 7, 12, 21, 30, and 40 after irradiation, 2 to 3 mice were assessed with dynamic FDG-PET acquisition over 2 hours. Immediately after the FDG-PET the tumors were harvested for global gene expression analysis and immunohistochemical evaluation of GLUT1 and HK2. Different analytic parameters were used to process the dynamic PET data. RESULTS Radiation had no effect on key genes involved in FDG uptake and metabolism but did alter other genes in the HIF1α and glucose transport-related pathways. In contrast to the lack of effect on gene expression, changes in the protein expression patterns of the key genes GLUT1/SLC2A1 and HK2 were observed after radiation treatment. The changes in GLUT1 protein expression showed some correlation with dynamic FDG-PET parameters, such as the kinetic index. CONCLUSION (18)F-fluorodeoxyglucose positron emission tomography changes after RT would seem to represent an altered metabolic state and not a direct effect on the key genes regulating FDG uptake and metabolism.

Abstract
Derailed endocytosis is a hallmark of cancer. The endocytic pathway, as demonstrated by our laboratory, is a frequent target of genomic aberrations in cancer and plays a critical role in the maintenance of cellular polarity, stem cell function, bioenergetics, proliferation, motility, invasion, metastasis, apoptosis and autophagy. The Rab GTPases, along with their effectors, are critical regulators of this endocytic machinery and can have a huge impact on the cellular itinerary of growth and metabolism. Rab25 is an epithelial-cell-specific member of the Rab GTPase superfamily, sharing close homology with Rab11a, the endosomal recycling Rab GTPase. RAB25 has been implicated in various cancers, with reports presenting it as both an oncogene and a tumour-suppressor gene. At the cellular level, Rab25 was shown to contribute to invasiveness of cancer cells by regulating integrin trafficking. Recently, our laboratory uncovered a critical role for Rab25 in cellular energetics. Assimilating all of the existing evidence, in the present review, we give an updated overview of the complex and often context-dependent role of Rab25 in cancer.
