Abstract
Background Survivin has been recently identified as a promising novel therapeutic target and prognostic marker in different types of cancer. Here we conducted a comprehensive meta-analysis to better clarify they the precise prognostic and diagnostic value of survivin in head and neck squamous cell carcinoma (HNSCC). Methods Database of PubMed (Medline), Embase, and Web of Science were systematically searched for related published literature up to September 2020. Pooled hazards ratios (HR) and related 95% confidence intervals (CI) were used to estimate the association of survivin expression and survival outcomes in HNSCC patients. Results Twenty eight studies with 4891 patients were finally included in this meta-analysis, the pooled analysis indicated that the survivin expression was significantly correlated with poorer overall survival (OS) (HR, 2.02; 95% CI, 1.65–2.47, P < 0.001), and poorer disease-free survival (DFS)/ disease-specific survival (DSS) (HR = 2.03, 95%CI: 1.64–2.52, P < 0.001; HR = 1.92, 95%CI: 1.41–2.60, P < 0.001, receptively). Similar results were observed in subgroup analysis stratified by different cancer types, such as laryngeal squamous cell carcinoma (LSCC) (HR = 1.35, 95%CI: 1.05–1.74, P < 0.001), oral squamous cell carcinomas (OSCC) (HR = 2.45, 95%CI: 1.89–3.17, P < 0.001), nasopharyngeal carcinoma (NPC) (HR = 2.53, 95%CI: 1.76–3.62, P < 0.001) and HNSCC (HR = 1.52, 95%CI: 1.25–1.86, P < 0.001). Furthermore, ethnicity-stratified analysis indicated that survivin was significantly associated with poorer OS among both Asian and Non- Asian HNSCC patients (HR = 2.16, 95%CI: 1.76–2.66; HR = 1.56, 95%CI: 1.33–1.82, respectively). Conclusions Our results suggested that survivin is predictors of worse prognosis in HNSCC patients. Hence, survivin is a potential therapeutic target for HNSCC.

Abstract
The objective of this study was to evaluate the expression of survivin and p16 in laryngeal squamous cell carcinoma (LSCC) in order to analyze their pathogenesis and prognostic significance in Tunisian patients. A total of 70 patients with LSCC collected at the Salah Azaiez Cancer Institute of Tunis were retrospectively evaluated. Expression of survivin and p16 was examined using immunohistochemistry, and the correlations with clinicopathological parameters, overall survival (OS), and disease-free survival (DFS) were statistically evaluated. The positive expression of survivin and p16 were found in 58.6% and 51.43% of LSCC cases, respectively. The p16 expression was not associated with either clinical parameters or patient survival, whereas there was a strong correlation of survivin expression and lymph node metastases (P = .002), alcohol consumption (P = .024), and therapeutic protocol (with or without chemotherapy; P = .001). Kaplan-Meier survival curves showed that patients with LSCC having positive survivin expression have shorter OS (P = .026) and shorter DFS (P = .01) than those with negative expression. Positive survivin expression was also correlated with high recurrence rate (P = .014). Therefore, survivin is a poor prognostic marker for LSCC but the therapeutic protocol remains, in multivariate study, the most decisive for the OS and DFS of our patients with P < .01. Our data indicated that, in Tunisian laryngeal squamous cell carcinoma, survivin expression is associated with unfavorable outcomes and represents a predictor marker of recurrence and chemoresistance. However, p16 expression has no prognosis value.

Effect and Mechanism of Survivin on Hypoxia-Induced Multidrug Resistance of Human Laryngeal Carcinoma Cells. BIOMED RESEARCH INTERNATIONAL 2019; 2019:5696801. [PMID: 31179330 PMCID: PMC6507141 DOI: 10.1155/2019/5696801] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Revised: 11/29/2018] [Accepted: 03/19/2019] [Indexed: 12/14/2022]
Abstract
This study aimed at clarifying the mechanism and role of survivin in hypoxia-induced multidrug resistance (MDR) of laryngeal carcinoma cells. Human laryngeal cancer cells were incubated under hypoxia or normoxia. The expression of survivin was silenced by performing RNA interference. Additionally, by Western blot and real-time quantitative RT-PCR, survivin expression was detected. The sensitivity of human laryngeal carcinoma cells to multiple drugs was measured by CCK-8 assay. Meanwhile, the apoptosis of cells induced by cisplatin or paclitaxel was assessed by Annexin-V/propidium iodide staining analysis. Under hypoxic conditions, the upregulation of survivin was abolished by RNA interference. Then, CCK-8 analysis demonstrated that the sensitivity to multiple agents of laryngeal carcinoma cells could be increased by inhibiting survivin expression (P < 0.05). Moreover, Annexin-V/propidium iodide staining analysis revealed that decreased expression of survivin could evidently increase the apoptosis rate of laryngeal carcinoma cells that were induced by cisplatin or paclitaxel evidently (P < 0.05). Our data suggests that hypoxia-elicited survivin may exert a pivotal role in regulating hypoxia-induced MDR of laryngeal cancer cells by preventing the apoptosis of cells induced by chemotherapeutic drug. Thus, blocking survivin expression in human laryngeal carcinoma cells may provide an avenue for gene therapy.

Abstract
Squamous cell carcinoma (SCC) is the most common cancer worldwide. The treatment of locally advanced disease generally requires various combinations of radiotherapy, surgery, and systemic therapy. Despite aggressive multimodal treatment, most of the patients relapse. Identification of molecules that sustain cancer cell growth and survival has made molecular targeting a feasible therapeutic strategy. Survivin is a member of the Inhibitor of Apoptosis Protein (IAP) family, which is overexpressed in most of the malignancies including SCC and totally absent in most of the normal tissues. This feature makes survivin an ideal target for cancer therapy. It orchestrates several important mechanisms to support cancer cell survival including inhibition of apoptosis and regulation of cell division. Overexpression of survivin in tumors is also associated with poor prognosis, aggressive tumor behavior, resistance to therapy, and high tumor recurrence. Various strategies have been developed to target survivin expression in cancer cells, and their effects on apoptosis induction and tumor growth attenuation have been demonstrated. In this review, we discuss recent advances in therapeutic potential of survivin in cancer treatment.

Abstract
Background The aim of this study was to evaluate the value of semiquantitative analysis (SQA) of 99mTc-MIBI imaging in predicting early-stage cervical lymph node metastasis (CLNM) in thyroid carcinoma (TC). Material/Methods TC patients (n=106) undergoing surgical resection and histopathological examination were enrolled. All patients received 99mTc-MIBI imaging prior to surgery. P-glycoprotein (P-gp) expression was detected by PT-PCR and immunohistochemistry. With pathological results as the criterion standard, the diagnostic efficiency of 99mTc-MIBI imaging in predicting early-stage CLNM was evaluated. The correlation of P-gp with 99mTc-MIBI imaging was investigated. Logistic regression analysis was applied for analyzing the factors affecting early-stage CLNM. Results The detection rate and misdiagnosis rate of 99mTc-MIBI imaging for early-stage CLNM diagnosis were 87.3% and 12.7%, respectively. Receiver operating characteristic (ROC) curve analysis showed an accuracy of 99mTc-MIBI imaging of 85.85%. Preoperative 99mTc-MIBI scan showed statistical differences between metastasis and non-metastasis groups in early and delayed T/NT and washout rate (all P<0.05). The percentage of P-gp-expressing cells and the expression rate of P-gp gene both exhibited statistical differences between metastasis and no-metastasis groups (both P<0.05). Tumor diameter, lesion distribution, the percentage of P-gp-expressing cells, and the expression rate of P-gp gene were risk factors for CLNM (all P<0.05). Conclusions 99mTc-MIBI imaging has value in qualitative diagnosis of early-stage CLNM in TC. Tumor diameter, lesion distribution, the percentage of P-gp-expressing cells, and the expression rate of P-gp gene were risk factors for CLNM.

Abstract
In a previous study, it was demonstrated that hypoxia upregulated the multidrug resistance (MDR) of laryngeal cancer cells to chemotherapeutic drugs, with multidrug resistance 1 (MDR1)/P-glycoprotein (P-gp) expression also being upregulated. The present study aimed to investigate the role and mechanism of MDR1/P-gp on hypoxia-induced MDR in human laryngeal carcinoma cells. The sensitivity of laryngeal cancer cells to multiple drugs and cisplatin-induced apoptosis was determined by CCK-8 assay and Annexin-V/propidium iodide staining analysis, respectively. The accumulation of rhodamine 123 (Rh123) in the cells served as an estimate of drug accumulation and was evaluated by flow cytometry (FCM). MDR1/P-gp expression was inhibited using interference RNA, and the expression of the MDR1 gene was analyzed using reverse transcription-quantitative polymerase chain reaction and western blotting. As a result, the sensitivity to multiple chemotherapeutic agents and the apoptosis rate of the hypoxic laryngeal carcinoma cells increased following a decrease in MDR1/P-gp expression (P<0.05). Additionally, FCM analysis of fluorescence intensity indicated that the downregulated expression of MDR1/P-gp markedly increased intracellular Rh123 accumulation (P<0.05). Such results suggest that MDR1/P-gp serves an important role in regulating hypoxia-induced MDR in human laryngeal carcinoma cells through a decrease in intracellular drug accumulation.

Abstract
BACKGROUND Prostate cancer (PCa) is the most commonly diagnosed neoplasm and the second leading cause of cancer-related death among men in developed countries. There is no clear evidence showing the success of current screening tests in reducing mortality of PCa. In this study, we aimed to profile expressions of nine ABC transporters, ABCA5, ABCB1, ABCB6, ABCC1, ABCC2, ABCC3, ABCC5, ABCC10, and ABCF2, in recurrent, non-recurrent PCa and normal prostate tissues. METHODS A total of 77 (39 recurrent, 38 non-recurrent) radical prostatectomy and 20 normal prostate samples, obtained from Baylor College of Medicine Prostate Cancer program, were included into the study and divided into two independent groups as test and validation sample sets. Differential expression of selected ABC transporters was assessed using quantitative real-time PCR (qRT-PCR). Pearson's correlation test, receiver operating characteristics (ROC) analysis and Kaplan-Meier test were used for statistical analysis. RESULTS QRT-PCR results demonstrated the elevated expression of ABCA5, ABCB1, ABCB6, ABCC1, and ABCC2 as well as reduced expression of ABCC3 in PCa samples compared to normal prostate tissues. In addition, we found deregulation of ABCB1, ABCB6, ABCC3, and ABCC10 in recurrent PCa samples and validated differential expression of ABCB6, ABCC3, and ABCC10 in recurrent PCa compared to non-recurrent PCa. Pearson's correlation, ROC and Kaplan-Meier analysis revealed the power of these three ABC transporters for estimating prognosis of PCa. CONCLUSIONS We demonstrated differential expression of ABC transporters both in tumor versus normal and recurrent versus non-recurrent comparisons. Our data suggest ABCB6, ABCC3, and ABCC10 as valuable predictors of PCa progression.

Abstract
Survivin is a member of the inhibitor of apoptosis (IAP) family and has multifunctional properties that include aspects of proliferation, invasion and cell survival control. Survivin is a promising candidate for targeted cancer therapy as its expression is associated with poor clinical outcome, more aggressive clinico-pathologic features, and resistance to radiation and chemotherapy. In the present review the different properties of the Survivin splice variants are discussed and their activities correlated with different aspects of cancer cell biology, to include subcellular location. Special emphasis is placed on our current understanding of these Survivin splice variants influence on each other and on the phenotypic responses to therapy that they may control.

Abstract
BACKGROUND A derailed balance of cell proliferation and apoptosis is presumed to result in cell hyperplasia as a typical feature of nasal polyps. Survivin, a protein of the inhibitors of the apoptosis family is proposed to promote polyp formation. However, studies concerning survivin expression in chronic rhinosinusitis (CRS) with nasal polyps are rare and the specificity of the survivin expression in nasal polyps from individuals with aspirin-exacerbated respiratory disease (AERD) has not been investigated. METHODS Immunohistochemical survivin expression analysis was performed. Samples were taken from the ethmoid sinus of individuals with CRS with nasal polyps with and without AERD during sinus surgery and control specimens of the inferior turbinate from individuals without CRS. Cell cultures were stimulated with recombinant vascular endothelial growth factor (VEGF(165)) and the resulting survivin expression was analyzed by Western blot. RESULTS The survivin expression of 61 specimens was analyzed by quantitative immunohistochemistry and a potential VEGF-dependant stimulation of survivin in cell cultures was investigated. The survivin expression in nasal polyps from individuals with AERD was increased compared with the controls (median, 1194 versus 927 arbitrary units [A.U.]; p = 0.054). Western blot analysis revealed in vitro a VEGF-dependant regulation of survivin in nasal polyps from individuals without AERD, but not in those with AERD (p = 0.05). CONCLUSION Enhanced survivin expression might result in decreased apoptosis and cellular hyperplasia as a part of the largely unknown pathophysiology of nasal polyp formation. Furthermore, we hypothesize a pathological, VEGF-independent constitutive survivin expression in nasal polyps of individuals with AERD.

Abstract
UNLABELLED Abstract Conclusion: P-glycoprotein is abundantly expressed in certain parotid mucoepidermoid carcinoma tissues, known historically to be multidrug resistant. This discovery may be important in incrementally advancing our ability to develop alternative pharmacologic strategies to improve multi-modality tumor control. OBJECTIVE P-glycoprotein plays a functional role in promoting the efflux of drug metabolites in certain malignant tumors. With this understanding we immunohistochemically investigated the expression of P-glycoprotein in parotid mucoepidermoid carcinoma tissues and examined prognostic factors that contribute to the treatment of parotid cancer. METHODS Thirteen patients with mucoepidermoid carcinoma of the parotid gland were included. P-glycoprotein expression was immunohistochemically investigated by a modified avidin-biotin-peroxidase complex method using four different antibodies. RESULTS P-glycoprotein expression was observed in a higher percentage of patients with higher grade malignancy. The tumor size-related difference in P-glycoprotein expression was only significant for staining with one antibody, and no significant differences were observed with or without induction chemotherapy.
