    Used in conjunction with a PSA test, the PSE test boosts accuracy from 55% to 94% offering a more effective and precise method for detecting and diagnosing prostate cancer. [45] The 4Kscore combines total, free and intact PSA together with human kallikrein 2. [46] It is used to try to determine the risk of a Gleason score greater than 6. [46]

    Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the KLK3 gene.PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland in men and the paraurethral glands in women.

    This enzyme complex then catalyzes the conversion of the enhanced chemiluminescent substrate into a sensitized reagent in the vicinity of the molecule of interest, which on further oxidation by hydrogen peroxide, produces a triplet (excited) carbonyl, which emits light when it decays to the singlet carbonyl. Enhanced chemiluminescence allows ...

    Senescence-associated beta-galactosidase (SA-β-gal or SABG) is a hypothetical hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides.Senescence-associated beta-galactosidase, along with p16 Ink4A, is regarded to be a biomarker of cellular senescence.

    Richard J. Ablin (May 15, 1940 – October 6, 2023) [1] was an American scientist, most notable for research on prostate cancer.According to the Wall Street Journal: . Richard Ablin, a professor of pathology at University of Arizona College of Medicine, discovered the prostate-specific antigen (PSA) in 1970, and for nearly as long, he has argued that it should not be used for routine screening.

  7. Prostate cancer - Wikipedia

    en.wikipedia.org/wiki/Prostate_cancer

    Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder.Abnormal growth of the prostate tissue is usually detected through screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels.
