  1. The potentials of circulating miR-21, miR-221, and prostate-specific antigen (Prostate Health Index (PHI) serum level as biomarkers for prostate cancer (PC) have been established not only as diagnostic factors but also as prognostic markers.

  2. PSA measurements after surgery or radiation therapy with curative intent include groups of men with a diverse spectrum of prognosis for prostate cancer mortality.

  3. Mean serum PSA levels were significantly higher in polycystic ovary syndrome women compared to healthy women.

  4. This meta-analysis suggests that rs1058205 polymorphism of KLK3 is a risk factor for PCa development, polymorphism T>C of rs1058205 is associated with decreased susceptibility to PCa particularly in Caucasian population

  5. Five single-nucleotide polymorphisms, rs266881 (OR = 2.92, P < 0.0001), rs174776 (OR = 1.91, P < 0.0001), rs266875 (OR = 1.44, P = 0.016), rs35192866 (OR = 4.48, P = 0.025) and rs1810020 (OR = 2.08, P = 0.034) correlated with an increased risk of male infertility. On the other hand, c.206 + 235 T > C, was more freuqent in the control group, showing protective association.

  6. In advanced prostate cancer with PSA levels >1000 ng/mL, sufficient PSA-A2M is present in circulation to produce enzymatic activity against circulating small peptide hormones.

  7. The aim of the study was to examine treatment patterns/outcomes with abiraterone (abi)/enzalutamide (enza) throughout PSA progression and near the end of life...abiraterone (abi)/enzalutamide are frequently discontinued for PSA progression alone and continued at end of life . The clinical benefit of these practices warrants additional study.

  8. The functional role of glycosylation in prostate-specific KLK3 could pave the way to a deeper understanding of their biology and to medical applications.

  9. These results shed a light on the genetic background of Benign prostatic hyperplasia and associated lower urinary tract symptoms and its substantial influence on PSA levels.

  10. Studies indicate that ghgh level of gamma-seminoprotein (gama-SM)/Prostate-Specific Antigen (PSA) could be detected in the blood [Review].

  11. Genome-wide association study of prostate-specific antigen levels identifies novel loci independent of prostate cancer.

  12. 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

  13. 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.

  14. 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.

  15. PSA was the only independent predictor of extensive lymph node invasion and could be an important preoperative factor for stratifying high-risk patients.

  16. ue to the biocompatibility, multivalency, stability, and high structural homogeneity, the t-PSA-specific landscape phage demonstrates as a novel specific interface in biosensors.

  17. 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

  18. 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)

  19. 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.

  20. 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.

Prekallikrein (PK) Protein Profile

Protein Summary

Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers. This gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. Its protein product is a protease present in seminal plasma. It is thought to function normally in the liquefaction of seminal coagulum, presumably by hydrolysis of the high molecular mass seminal vesicle protein. Serum level of this protein, called PSA in the clinical setting, is useful in the diagnosis and monitoring of prostatic carcinoma. Alternate splicing of this gene generates several transcript variants encoding different isoforms.
