PSA

abbreviation for
1. (Biochemistry) prostatic specific antigen: an enzyme secreted by the prostate gland, increased levels of which are found in the blood of patients with cancer of the prostate
2. (Social Welfare) (in New Zealand) Public Service Association

PSA

prostate specific antigen: a protein, produced by the prostate, elevated levels of which may indicate the presence of cancer.
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.PSA - a protein manufactured exclusively by the prostate gland; PSA is produced for the ejaculate where it liquifies the semen and allows sperm cells to swim freely; elevated levels of PSA in blood serum are associated with benign prostatic hyperplasia and prostate cancer
protein - any of a large group of nitrogenous organic compounds that are essential constituents of living cells; consist of polymers of amino acids; essential in the diet of animals for growth and for repair of tissues; can be obtained from meat and eggs and milk and legumes; "a diet high in protein"
Translations

Analyzing DLX1 and HOXC6 biomarkers, using KLK3 expression as internal reference combined with age, DRE results, and PSA level, this test provides percent likelihood of having any prostate cancer and percent likelihood of having high-grade prostate cancer (Leyten et al.
A large-scale analysis of genetic variants in miRNA binding sites identified 22 prostate cancer risk associated miRSNPs, the 2 most significant miRSNPs being KLK3 (kallikrein related peptidase 3) rs1058205 (T>C) and VAMP8 (vesicle associated membrane protein 8) rs1010 (A>G), which were targeted by miR-3162-5p and miR-370-5p respectively in an allele specific manner (77).
Of note, the prostate-specific antigen (PSA [kallikrein3 protein; KLK3, gene]) is expressed and secreted by human but not mouse luminal prostate cells, which secrete other proteins that seem to be lobe-specific [39, 40].
They analysed associations of the SNPs with disease aggression and found that the KLK3 gene can predict an aggressive form of GS7 disease.
KLK3 encodes PSA was one of the six loci identified by GWAS that were associated with higher PSA levels in patients without prostate cancer [151].
The genes that were more highly expressed in carcinomas treated with androgen ablation agents included those encoding AR and steroid biosynthetic enzymes, as well as a suite of genes that have been previously shown to be targets of AR or have been implicated as being regulated by it, including the gene encoding PSA (kallikrein-related peptidase 3), KLK3, and KLK2, as well as DBI, FASN, IL6, SERPINB5, TGFBR3, TMPRSS2, TUBA1, HOXC6, TRG ,and FOLH1.
PSA and human kallikrein 2 are closely related products of human kallikrein genes KLK3 and KLK2, respectively.
In the paper being published in The Journal of Biological Chemistry, Compugen's scientists report the identification of unusual mRNA splice variants of the KLK2 and KLK3 genes.
To address this question, we examined the relationship between SNPs in KLK2 and KLK3 and concentrations of hK2 and PSA in serum and seminal plasma by use of a population-based cohort of young men in whom prostate conditions are very rare.

PSA is encoded by KLK3 [8] (kallikrein-related peptidase 3), a member of a family of 15 kallikrein genes located on human chromosome 19 (4).
