Gene References into Functions
  1. Genome-wide association study of prostate-specific antigen levels identifies novel loci independent of prostate cancer. PMID: 28139693
  2. Men with mild to no lower urinary tract symptoms (LUTS) but increased baseline PSA are at increased risk of developing incident LUTS presumed due to benign prostatic hyperplasia PMID: 29795141
  3. PSA-density might inform biopsy decisions, and spare some men from the morbidity associated with a prostate biopsy and diagnosis of low-grade prostate cancer. PMID: 29259293
  4. Differences in fPSA-recovery between all investigated assays were even more pronounced. When applying the tPSA cutoff of 3.1 mug/L recommended for WHO-calibrated assays, the use of higher calibrated assays may lead to unnecessary prostate biopsies. Conversely, if the historical threshold of 4 mug/L is applied when using WHO-calibrated assays, it could lead to falsely omitted prostate biopsies. PMID: 29734838
  5. PSA was the only independent predictor of extensive lymph node invasion and could be an important preoperative factor for stratifying high-risk patients. PMID: 29714659
  6. ue to the biocompatibility, multivalency, stability, and high structural homogeneity, the t-PSA-specific landscape phage demonstrates as a novel specific interface in biosensors. PMID: 29414091
  7. Based on the target-induced catalytic hairpin assembly and bimetallic catalyst, the enzyme-free recycling amplification strategy for sensitive detection of prostate specific antigen (PSA) has been designed PMID: 29156407
  8. The prepared biosensor can assay from 0 to 500ng/mL of prostate specific antigen (PSA) level within 2h with the detection limit of 1.18ng/mL by the measurement of resistance change. The resistance change was caused by site selective interaction between PSA and PSA-antigen with an inexpensive bench top digital multimeter (5 1/2 digits) PMID: 29172142
  9. he superwettable f-PSA microchip can accurately detect human serum samples with excellent correlations with chemiluminescence immunoassay in the clinic, demonstrating its great potential as a sensitive and reliable sensing platform for biological analysis and clinical diagnosis. PMID: 29175217
  10. The 12-week PSA response rate was 88% (22/25) and 22% (4/18), median time to PSA progression was 18.2 months [95% confidence interval (CI), 8.3 months-not reached) and 3.7 months (95% CI, 2.8-5.6 months), and median time on treatment 21 months (range, 2.6-37.5) and 4.9 months (range, 1.3-23.2), for the AAP-naive and post-AAP cohorts, respectively. PMID: 28213364
  11. The results support that u-PSA provides useful information for predicting predicting biochemical recurrence after radical prostatectomy . This can be beneficial to avoid unnecessary adjuvant treatments or to start them earlier for selected patients PMID: 27805011
  12. this meta-analysis suggests that PSA -158G/A polymorphism may be a protecting factor against BPH in Caucasian populations, but it may enhance the disease risk in Asians. PMID: 28430620
  13. Developed risk assessment models for North Chinese patients with 4-50 ng/mL PSA to reduce unnecessary prostate biopsies and increase the detection rate of prostate cancer. PMID: 28039477
  14. Data show positive associations of relative Gal-3 and relative PSA levels in prostate cancer patients, notably at early clinical time course. PMID: 27741512
  15. Both the extent of comorbidity and the PSA doubling time should be taken into consideration when deciding on appropriate management and/or clinical trial eligibility at the time of PSA failure. PMID: 28117382
  16. As restaging in advanced prostate cancer patients is often guided by increases in PSA levels, our results demonstrate that disease progression on enzalutamide can occur without rising PSA levels. Therefore, a disease monitoring strategy that includes imaging not entirely reliant on serial serum PSA measurement may more accurately identify disease progression. PMID: 28117385
  17. Older men who underwent no PSA testing or incomplete testing were significantly more likely to be diagnosed with high-risk prostate cancer than those who were previously screened. It is reasonable to consider screening in healthy older men likely to benefit from early detection and treatment. PMID: 28045113
  18. end-of-radiation PSA was significantly associated with survival endpoints in men who received treatment with definitive radiation and ADT. Whether the EOR PSA can be used to modulate treatment intensity merits further investigation. PMID: 28094250

  21. Microenvironmental acidity determines qualitatively and quantitatively the release of extracellular vesicles by malignant prostate tumors. This leads to the spill-over of nanovesicles into the peripheral blood of prostate cancer patients, where the levels of tumor biomarkers expressed by exosomes, such as PSA-exosomes, may represent a novel, non-invasive diagnostic tool. PMID: 28694142
  22. Promoter methylation of MCAM, ERalpha and ERbeta have a potential to be utilized as biomarker for the early detection of prostate cancer (PC) as their sensitivity and specificity seem to be better than serum PSA. PMID: 28147335
  23. Data suggest no influence of chronic periodontitis treatment on PSA levels in asymptomatic men. PMID: 28551659
  24. Circulating total PSA levels were strongly associated to leukocyte telomere length in a national sample of men without prostate cancer. PMID: 27566127
  25. I might also point out that whether a particular surgical procedure did more good than harm at that time was highly dependent on whether it was conducted with good sterile procedure. PSA screening is a contemporary example of this historical lesson PMID: 27010733
  26. Data show that forkhead box M1 protein (FOXM1) directly binds to the FHK binding motifs in the prostate specific antigen (PSA) promoter/enhancer regions. PMID: 28199985
  27. Study suggests that the prognostic value of PSA declines in heavily treated patients receiving enzalutamide PMID: 28614217
  28. novel urinary gene expression signature that may be the least invasive of available options by not requiring a digital rectal examination or phlebotomy as a reflex test in men for whom PSA testing raises the suspicion of prostate cancer PMID: 27031887
  29. For PSA screening to be cost-effective, it needs to be used conservatively and ideally in combination with a conservative management approach for low-risk disease PMID: 27010943

  33. Purified PSA cleaves complement factor iC3b in a previously uncharacterized function of PSA as an immunoregulatory serine protease that can help create an environment hospitable to malignancy through proteolysis of the complement system. PMID: 23401592
  34. Extended follow-up of the PLCO trial over a median of 15 years continues to indicate no reduction in prostate cancer mortality for the intervention arm versus the control arm. Because of the high rate of control-arm PSA testing, this finding can be viewed as showing no benefit of organized screening versus opportunistic screening PMID: 27911486
  35. Data indicate that prostate specific antigen (PSA) is a negative predictive biomarker for local recurrence during follow-up. PMID: 27834929
  36. TC genotype of rs1058205 lower in prostate cancer group than in control group; TT genotype associated with prostate cancer PMID: 28272245
  37. The prostate-specific antigen density (PSAD) cutoff level generated for Nigerian men in this study is 0.04 which is relatively different from international consensus. This PSAD cutoff level has a positive correlation with histology and could detect patients with prostate cancer who have "grey zone PSA." PMID: 27356753
