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.
The highest levels of acid phosphatase are found in metastasized prostate cancer. Diseases of the bone, such as Paget's disease or hyperparathyroidism, diseases of blood cells, such as sickle-cell disease or multiple myeloma or lysosomal storage diseases, such as Gaucher's disease, will show moderately increased levels.
The LNCaP (Lymph Node Carcinoma of the Prostate) cell line was established from a metastatic lesion of human prostatic adenocarcinoma.The LNCaP cells grow readily in vitro (up to 8 x 10 5 cells/sq cm; doubling time, 60 hr), form clones and are highly resistant to human fibroblast interferon. [1]
The corresponding specific proteins are expressed in the glandular and secretory cells of the prostatic gland and have functions that are important for the characteristics of semen, including prostate-specific proteins, such as the prostate specific antigen (PSA), and the prostatic acid phosphatase.
Skene's glands produce a milk-like ultrafiltrate of blood plasma. The glands may be the source of female ejaculation , [ 3 ] [ 4 ] [ 5 ] but this has not been proven. [ 4 ] Because they and the male prostate act similarly by secreting prostate-specific antigen (PSA), which is an ejaculate protein produced in males, and prostatic acid ...
Properties of common prostate cancer cell lines. PC3 (PC-3) is a human prostate cancer cell line used in prostate cancer research and drug development. [1] PC3 cells are useful in investigating biochemical changes in advanced prostate cancer cells and in assessing their response to chemotherapeutic agents.
Within immunology, we saw sales growth in Tremfya of 5.6%, driven by strong market growth and share gains in PsO and PsA, partially offset by unfavorable patient mix and inventory dynamics.
Prostate-specific antigen. Prostate-specific antigen (PSA) is secreted by the epithelial cells of the prostate gland and can be detected in a sample of blood. [14] PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer or other prostate disorders. [15]
