A functional variant at miRNA-122 binding site in IL-1a 3' UTR predicts risk of recurrence in patients with oropharyngeal cancer.
(Oncotarget, 2016-06)IL-1a, an important regulator of immune and inflammation responses, has been implicated in cancer development and prognosis. An insertion (Ins)/deletion (Del) polymorphism (IL-1a rs3783553) in the 3' UTR of IL-1a may disrupt ... -
A TGF-β1 genetic variant at the miRNA187 binding site significantly modifies risk of HPV16-associated oropharyngeal cancer.
(International journal of cancer, 2018-09)TGF-β1rs1982073 polymorphism at the miRNA-187 binding site may alter TGF-β1 expression and function, and thereby this polymorphism (genotype CT/CC) increases cancer susceptibility. HPV16 L1 seropositivity is associated with ... -
Apoptotic variants as predictors of risk of oropharyngeal cancer recurrence after definitive radiotherapy.
(Int J Cancer, 2015-11-15)Single nucleotide polymorphisms (SNPs) in the promoter region of FAS and FASLG may alter their transcriptional activity. Thus, we determined the associations between four FAS and FASLG promoter variants (FAS1377G>A, rs2234767; ... -
Association of combined p73 and p53 genetic variants with tumor HPV16-positive oropharyngeal cancer.
(PloS one, 2012-01)p53 and p73 interact with human papillomavirus (HPV) E6 and E7 oncoproteins. The interplay between p53 and p73 and HPV16 may lead to deregulation of cell cycle and apoptosis, through which inflammation/immune responses control ... -
Association of tumor necrosis factor-alpha promoter variants with risk of HPV-associated oral squamous cell carcinoma.
(Molecular cancer, 2013-07-19)Tumor necrosis factor alpha (TNF-α) plays an important role in inflammation, immunity, and defense against infection and clearance of human papillomavirus (HPV). Thus, genetic variants may modulate individual susceptibility ... -
Associations between expression levels of nucleotide excision repair proteins in lymphoblastoid cells and risk of squamous cell carcinoma of the head and neck.
(Molecular carcinogenesis, 2018-06)Squamous cell carcinoma of head and neck (SCCHN) is one of the most common malignancies worldwide, and nucleotide excision repair (NER) is involved in SCCHN susceptibility. In this analysis of 349 newly diagnosed SCCHN patients ... -
Genetic variants of NOXA and MCL1 modify the risk of HPV16-associated squamous cell carcinoma of the head and neck.
(BMC cancer, 2012-05)The cooperation between phorbol 12-myristate 13-acetate induced protein 1 (NOXA) and myeloid cell leukemia 1 (MCL1) is critical in the intrinsic apoptotic pathway. Human papillomavirus 16 (HPV16), by inducing p53 and pRb-E2F ... -
Genetic variants of p27 and p21 as predictors for risk of second primary malignancy in patients with index squamous cell carcinoma of head and neck.
(Molecular cancer, 2012-03-26)Cell cycle deregulation is common in human cancer, and alterations of p27 and p21, two critical cell cycle regulators, have been implicated in the development of many human malignancies. Therefore, we hypothesize that p27 ... -
Genetic variation in MDM2 and p14ARF and susceptibility to salivary gland carcinoma.
(PloS one, 2012-01)The p14(ARF)/MDM2/p53 pathway plays an important role in modulation of DNA damage and oxidative stress responses. The aim of this study was to determine whether genetic variants in MDM2 and p14(ARF) are associated with risk ... -
HPV16 antibodies as risk factors for oropharyngeal cancer and their association with tumor HPV and smoking status.
(Oral Oncol, 2015-07)BACKGROUND: Antibodies (Abs) to the HPV16 proteome increase risk for HPV-associated OPC (HPVOPC). The goal of this study was to investigate the association of a panel of HPV16 Abs with risk for OPC as well as the association ... -
Lymphocyte Telomere Length Predicts Clinical Outcomes of HPV-Positive Oropharyngeal Cancer Patients after Definitive Radiotherapy.
(Carcinogenesis, 2019-02-05)Since lymphocyte telomere length (LTL) plays critical roles in the maintenance of genomic stability and integrity, LTL thus may influence the etiology and prognosis of squamous cell carcinoma of the oropharynx (SCCOP). However, ... -
MicroRNA variants increase the risk of HPV-associated squamous cell carcinoma of the oropharynx in never smokers.
(PloS one, 2013-01)Both microRNAs and human papillomavirus (HPV) infection play an important role in the development and progression of oral squamous cell carcinoma (OSCC). In addition, microRNAs affect all facets of the immune/inflammation ... -
Modifying effect of mouse double minute-2 promoter variants on risk of recurrence for patients with squamous cell carcinoma of oropharynx.
(Scientific reports, 2017-01-03)Functional mouse double minute-2 (MDM2) promoter variants may alter MDM2 expression and thus affect radiotherapy response and prognosis of squamous cell carcinoma of oropharynx (SCCOP). Thus we assessed association of 2 ... -
Mouse double minute 4 variants modify susceptibility to risk of recurrence in patients with squamous cell carcinoma of the oropharynx.
(Molecular carcinogenesis, 2018-03)Given the crucial role of Mouse double minute 4 (MDM4) oncoprotein in p53 pathway, single nucleotide polymorphisms (SNPs) could serve as such biomarkers for prediction of SCCOP recurrence. Thus, we investigated associations ... -
Pre-miRNA variants as predictors of clinical outcome in patients with squamous cell carcinomas of the nonoropharynx.
(Oncotarget, 2016-05)Functional polymorphisms of miRNAs may affect the function and target expression of miRNAs, which can, in turn, affect the biological activity, etiology, and prognosis of cancer. We hypothesized that four common polymorphisms ... -
Significance of microRNA-related variants in susceptibility to recurrence of oropharyngeal cancer patients after definitive radiotherapy.
(Oncotarget, 2016-06)Common single nucleotide polymorphisms (SNPs) in miRNAs may affect miRNA functions and their target expression and thus may affect biological activities and cancer etiology as well as prognosis. Thus, we determined whether ... -
Site disparities in apoptotic variants as predictors of risk for second primary malignancy in patients with squamous cell carcinoma of the head and neck.
(BMC cancer, 2016-02-08)FAS/FASL promoter variants are considered in altering transcriptional activity of those genes and consequently alter regulation of cell death. However, no studies have investigated whether tumor sites contribute ... -
TGFβ1 Genetic Variants Predict Clinical Outcomes of HPV-Positive Oropharyngeal Cancer Patients after Definitive Radiotherapy.
(Clinical cancer research : an official journal of the American Association for Cancer Research, 2018-05)Purpose: TGFβ1 plays a critical role in inflammation and immune responses and treatment response and survival. TGFβ1 variants may affect its expression level or functional efficiency, thus modifying tumor status and survival ...
