Abstract
Purpose Circular RNAs (circRNAs) are novel type of noncoding RNAs that play important roles and serve as noninvasive biomarkers in various cancers. In the present study, we focused on circFoxO3a and aimed to investigate its prognostic value as a novel serum biomarker for squamous cervical cancer (SCC). Patients and Methods Our study included 103 SCC patients from Obstetrics and Gynecology Hospital of Fudan University. Expression levels of circFoxO3a in the serum of patients with SCC were examined by reverse transcription‑quantitative PCR (RT‑qPCR). The correlation between serum circFoxO3a expression and clinicopathologic factors was analyzed. The Kaplan–Meier method and multivariate Cox regression analysis were applied to evaluate the independent prognostic factors for SCC. A prognostic predictive nomogram was constructed using R software. Results Levels of serum circFoxO3a were decreased in SCC patients compared with controls. Low expression of circFoxO3a was correlated with deeper stromal invasion and positive lymph node metastasis. Moreover, SCC patients with lower expression of serum circFoxO3a showed poorer prognosis, including both overall survival (OS) and recurrence-free survival (RFS). Multivariate Cox analysis indicated low serum circFoxO3a levels to be an unfavorable prognostic factor for both OS and RFS, independent of positive lymph node metastasis. Notably, the predictive nomogram we established further confirmed that serum circFoxO3a is a useful tool for predicting survival in SCC. Conclusion Altogether, our findings demonstrated that serum circFoxO3a could serve as a potential novel noninvasive predictive prognostic biomarker and therapeutic target for SCC.

Serum SCCA levels in patients suffering cancers or other diseases. PROGRESS IN MOLECULAR BIOLOGY AND TRANSLATIONAL SCIENCE 2019; 162:165-175. [PMID: 30905447 DOI: 10.1016/bs.pmbts.2018.12.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/17/2022]
Abstract
Increased serum squamous cell carcinoma antigen (SCCA) levels are clinically used diagnostic or prognostic biomarker for squamous cell carcinomas. According to recently published studies, increased serum SCCA levels are also observed in adenocarcinomas, hepatocarcinomas, kidney, and other inflammatory diseases, indicating squamous cell carcinoma is not the production source of serum SCCA in these diseases. However, serum SCCA levels in patients suffering different types of diseases have not been systematically measured and compared. Thus, in our current study, serum SCCA levels from 21,608 patients with 39 clinically defined diseases were collected and measured by the clinical laboratory in the Affiliated Hospital of Qingdao University over the past 5 years in addition to 232 serum samples from individuals who attend their annual physical examination as the healthy controls. According to the median, mean, and -log10p values, we found that patients with uremia, azotemia, diabetic nephropathy, and nephritic syndrome had the highest serum SCCA levels among all 39 different types of diseases including patients suffering squamous cell carcinomas. Moreover, patients suffering lung cancer, cervical cancer, esophagus cancer, or chronic pulmonary disease had lower median and interquartile range values but higher or comparable mean values and significantly higher SD values than that of the healthy controls. Furthermore, patients with endometrial cancer, pancreatitis, osteoporosis, and some other diseases had lower serum SCCA levels than that of the healthy controls. These results demonstrated that serum SCCA can not only be used in diagnosis and prognosis of squamous cell carcinomas but also as biomarkers for uremia, azotemia, diabetic nephropathy, and nephritic syndrome.

FEBS Open Bio 2018; 8:1280-1298. [PMID: 30087832 PMCID: PMC6070648 DOI: 10.1002/2211-5463.12478] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2018] [Revised: 05/19/2018] [Accepted: 06/11/2018] [Indexed: 12/28/2022] Open
Abstract
MicroRNAs (miRNAs) are confirmed to be tumor promoters or suppressors in multiple squamous cell carcinomas (SCCs). miR‐99a‐5p has been demonstrated to be downregulated in cancerous tissues, but its functional role in head and neck SCC (HNSCC) and its mechanism of action have not been fully elucidated. Here, we studied the expression of miR‐99a‐5p in HNSCC and performed a clinical value assessment and then extracted mature expression data from The Cancer Genome Atlas (TCGA) and microarrays from Gene Expression Omnibus (GEO). Furthermore, biological analysis was constructed via online prediction tools. The results revealed that miR‐99a‐5p expression was markedly lower in HNSCC tissues than in normal tissues, which also showed significance in the prognosis of HNSCC. However, its diagnostic value could not be verified due to the lack of body fluid samples. Additionally, miR‐99a‐5p was expressed at higher levels in patients with low histological grade neoplasms than those with high histological grade neoplasms. The age of the patient might also be a possible clinical parameter affecting miR‐99a‐5p expression. Furthermore, miR‐99a‐5p significantly influenced HNSCC progression by regulating the PI3K‐Akt signaling pathway, in which the key target genes were upregulated in 519 HNSCC tissues compared to 44 normal tissues, as determined by the Gene Expression Profiling Interactive Analysis (GEPIA). In conclusion, our study may provide insights into the expression and mechanism of miR‐99a‐5p in HNSCC. Further studies are required to elucidate the role of miR‐99a‐5p and its potential clinical applications for HNSCC.
