Micro-ribonucleic acids (miRNAs) are endogenous single-stranded small non-coding RNAs. miRNAs bind to a com-plementary site in the 3' untranslated region of their target mRNAs through canonical base pairing, which can direct the degradation or translational repression of these transcripts. Thus, miRNAs can effectively silence the protein expression of target genes post-transcrip-tionally. miRNAs may also regulate the expression of oncogenes and tumor suppressor genes and could be involved in almost all known hallmarks of cancinogenesis. In this paper, we discuss the following in detail:(1) biogenesis and main functions of cellular miR-NAs, (2) stability and detectability of exosomal miRNAs in biological fluids;and (3) feasibility of miRNAs as a potential new class of biomarkers derived from urinary exosome in the malignancy of urinary system. Finally, we summarize studies on urinary exosomal miRNAs as potential biomarkers of prostate, bladder, and kidney cancers.

Objective: To investigate the molecular changes in bladder urothelial carcinoma via different pathways. Methods:Polymerase-chain reaction (PCR) or coamplification at low denaturation temperature-PCR and Sanger direct sequencing were per-formed to detect the status of fgfr3, p53, and h-ras gene mutations in 88 tissue samples of human bladder cancer and 10 normal control tissues. The relative mRNA expression levels of motility-related protein-1 (MRP-1)/CD9 and the relationship between genes and tumor recurrence were also determined. Logistic regression and relative analyses were conducted to compare the significance and interrelation of genes among tumor recurrences. Results:The mutation rate of p53 increased as pathological grades and stages increased. Recurrence rate was higher in patients with MT-p53 genotype than in patients with WT-p53 genotype. Conversely, the mutation rate of fgfr3 gene decreased as pathological grades and stages increased. Recurrence rate was also higher in patients with WT-fgfr3 genotype than in pa-tients with MT-fgfr3 genotype. In low-grade and early stage tumors, MT-fgfr3/WT-p53 was the most prevalent genotype;in high-grade and late stage tumors, WT-fgfr3/MT-p53 was the most prevalent genotype. The mutations of h-ras were mainly observed in low-grade tumors in early stages. Moreover, the relative mRNA levels of MRP-1/CD9 decreased as pathological grades and stages increased. The mRNA levels of MRP-1/CD9 were negatively correlated with p53 mutations and positively correlated with fgfr3 mutations. Logistic re-gression analysis results showed that patients with WT-fgfr3 genotypes exhibited 3.88 times higher relative risk of tumor recurrence than those with MT-fgfr3 genotypes;by contrast, patients with MT-p53 genotypes exhibited 4.53 times higher relative risk of tumor re-currence than those with WT-p53 genotypes. Conclusion:Fgfr3 and h-ras gene mutations may play important roles in tumorigenesis of low-grade and early stage bladder cancer. p53 gene mutation and mRNA levels of MRP-1/CD9 may be implicated in the tumorigenesis of high-grade tumors in late stage of bladder cancer. In general, the two variants of urothelial carcinoma exhibit distinct genetic defects. fgfr3 gene mutation revealed a pathway of favorable prognosis, and p53 gene mutation demonstrated a pathway associated with poor prognosis.

Treatment and the clinical outcome of patients with head and neck cancer are determined by accurate staging and assessment of the cervical lymph nodes for metastases is an important step of this process. Ultrasonography, ultrasonography-guided fine needle aspiration (FNA), CT, MRI and PET/CT are used in the assessment of cervical lymph nodes. Ultrasonography guided FNA is advantageous in ease of application, minimumal invasiveness to patients, and less contraindications. Combined with cell block and molecular biology, FNA can be an effective tool for the diagnosis. The present article reviewed the diagnostic value of ultrasonography guided FNA in cervical lymph node assessment in patients with head and neck cancer.
