Immunohistochemical expression of Ki-67, Cyclin D1, p16INK4a, and Survivin as a predictive tool for recurrence and progression-free survival in papillary urothelial bladder cancer pTa / pT1 G2 (WHO 1973).
However, P16 gene amplification accompanied protein high-expression has shorter overall survival compared with the overall patients (P = .023), and P16 gene loss accompanied loss of protein also had the tendency to predict bad prognosis (P = .067).Studies show that the genetic status of P16 has a close relation with the stages of bladder cancer.
Overall, we verified that miR-892b regulates the p19ARF/cyclin D1/CDK6 and Sp-1/MMP-9 signaling networks in bladder cancer cells and may provide a treatment option for advanced-stage bladder cancers.
The amplification of YWHAZ, along with alteration of CDKN2A or TP53, predict better survival in bladder cancers that only had CDKN2A or TP53 alteration.
In conclusion, DE-miRNAs in bladder cancer tissue samples and DE-targeted genes, such as miR-106b and CDKN2A, which were identified in the present study, may provide the basis for targeted therapy for breast cancer and enhance understanding of its pathogenesis.
Some cytogenetic anomalies present in UBC were found in the three cell lines, such as chromosome 20 aneuploidy and the loss of 9p21.Some gene loci losses (e.g.CDKN2A) and gains (e.g.
ASSET analyses identified four SNPs significantly associated with multiple cancers: rs3731239 (CDKN2A intronic) with ESCC, GC and BC (P = 3.96 × 10(-) (4)); rs10811474 (3' of IFNW1) with RCC and BrC (P = 0.001); rs12683422 (LINGO2 intronic) with RCC and BC (P = 5.93 × 10(-) (4)) and rs10511729 (3' of ELAVL2) with LC and BrC (P = 8.63 × 10(-) (4)).
p14 hypermethylation could be involved in early stage of bladder carcinogenesis, and p14 hypermethylation in pathologically normal urothelium samples should be considered a predictor of bladder cancer recurrence.
Detecting DNA methylation of the BCL2, CDKN2A and NID2 genes in urine using a nested methylation specific polymerase chain reaction assay to predict bladder cancer.
We analyzed the methylation of P16INK4a and P14ARF in 80 tissues and matched blood samples of patients suffering from bladder cancer and 80 blood samples of cancer-free individuals by MS-PCR.
To evaluate the prognostic role of p16 expression and loss of heterozygosity (LOH) on chromosome 9p21 in patients affected by low-grade (G1-G2) urothelial bladder cancer.
We, therefore, examined, in a population-based study of human bladder cancer (n = 351), the relationship between epigenetic silencing of the tumor-suppressor genes, p16(INK4A), RASSF1A, PRSS3, and the four SFRP genes and exposure to both tobacco and arsenic in bladder cancer.
We, therefore, examined, in a population-based study of human bladder cancer, the relationship between epigenetic silencing of three tumor suppressor genes, p16(INK4A), RASSF1A and PRSS3, and exposure to both tobacco and arsenic in bladder cancer.

To determine p53 and p16 status as molecular markers of bladder cancer, in histologically proven benign bladder biopsies, obtained from lesions suspect for malignancy as judged by fluorescence cystoscopy.
We, therefore, examined, in a population-based study of human bladder cancer, the relationship between epigenetic silencing of three tumor suppressor genes, p16(INK4A), RASSF1A and PRSS3, and exposure to both tobacco and arsenic in bladder cancer.
Using methylation-specific PCR (MSP), we examined the methylation status of p16(INK4a) and p14(ARF) in 64 samples from 45 bladder cancer patients (34 males, 11 females).
DNA methylation on CpG islands of the p16 (0%, 17% and 21%) and death-associated protein kinase (13%, 33% and 29%) genes, and methylated in tumor-2 (56%, 60% and 76%), 12 (0%, 6% and 30%), 25 (25%, 27% and 35%) and 31 (45%, 56% and 79%) clones was detected in normal urothelium, NBCs and TCCs, respectively.
