The results indicate that allelic variation in PSA promoter activity may be androgen dependent and interaction of genes in androgen pathway may influence the risk of BPH and PC in Singapore males.
CYP19 1531 C>T, SRD5A2 gene V89L, CYP17 gene -34 T/C, PSA-158 (G/A) regions were evaluated for the association between polymorphisms and benign prostatic hyperplasia and prostate cancer in study population.
We investigated the relationship between polymorphisms in four genes, androgen receptor (AR), prostate-specific antigen (PSA), 5alpha-reductase type II (SRD5A2) and cytochrome P450c17alpha (CYP17) and PC and benign prostatic hyperplasia (BPH).
Molecular Analysis of the SRD5A1 and SRD5A2 Genes in Patients with Benign Prostatic Hyperplasia with Regard to Metabolic Parameters and Selected Hormone Levels.
A novel splice variant of PSA was identified, PSA-SV5, that may be exploited in clinical diagnosis to distinguish prostate cancer from benign prostate hyperplasia.
CYP19 1531 C>T, SRD5A2 gene V89L, CYP17 gene -34 T/C, PSA-158 (G/A) regions were evaluated for the association between polymorphisms and benign prostatic hyperplasia and prostate cancer in study population.
We therefore designed a case-control study of 105 prostate-cancer patients and 210 controls with benign prostatic hyperplasia for the purpose of investigating the association between prostate-cancer risk and polymorphisms in the SRD5A2 and CYP17 genes among the Japanese.
Association testing revealed no significant differences between familial prostate cancer patients and population controls (OR: 0.84; 95%CI, 0.56-1.28; p=0.42), unselected cases and controls (OR: 0.95; 95%CI, 0.76-1.19; p=0.63), or BPH cases and controls (OR: 1.12; 95%CI, 0.86-1.46; p=0.39). pCA and BPH cases were also compared with PSA-screened controls.
The aim of the study was to investigate any associations between benign prostate hyperplasia (BPH) and single nucleotide polymorphisms (SNPs) in the VDR gene (FokI, BsmI, ApaI and TaqαI loci) and the CYP17 gene (MspA1I locus), as well as TA repeat polymorphism in SRD5A2 gene among Lebanese men.
The SRD5A2 polymorphisms A49T, V89L and R227Q, the androgen receptor CAG and GGN repeats and sex hormone status was investigated in men with prostate cancer (CaP) (n=89), benign prostate hyperplasia (n=45) and healthy military conscripts (n=223).
To examine the role of the polymorphisms in the AR and PSA genes in prostate cancer susceptibility, we conducted a case-control study of Austrian Caucasians with 190 newly diagnosed prostate cancer patients and 190 age-matched control men with benign prostatic hyperplasia (BPH).
The replication alteration accompanied by aneuploidy, detected in peripheral blood cells, distinguishes between CAP patients and individuals with benign prostate hyperplasia (BPH; a common disorder in elderly men) better than the routinely used blood marker, the prostate-specific antigen (PSA).
The frequency of GG, AG, and AA genotypes of KLK3 polymorphism was 24.6% and 76.2%, 46.6% and 21.7%, and 28.8% and 2.1%, in patients with BPH and PC, respectively (P < 0.001).
For the first time, our data demonstrate that the correlation between SRD5A2 gene Ala49Thr and polymorphisms is statistically significant in Turkish men with BPH.
The PSA-158 G/A polymorphism was determined by PCR amplification and restriction digestion assays in 101 organ-confined prostate cancer (PC) patients who underwent radical prostatectomy and 52 controls with benign prostatic hyperplasia.
For example, precision medicine can facilitate the selection of men at high risk for prostate cancer for targeted prostate-specific antigen screening and chemoprevention administration, as well as assist in identifying men who are resistant to medical therapy for prostatic hyperplasia, who may instead require surgery.
We evaluated the association between 3 polymorphisms in the SRD5A2 gene (2 single nucleotide polymorphism: alanine-49 to threonine [A49T] and valine-89 to leucine [V89L], and a (TA)n dinucleotide repeat in the 3' untranslated region), and BPH and prostate cancer within a multiethnic population.
