NCIt definition : A synthetic 15-mer peptide corresponding to amino acids 31-45 of the 94-amino acid
isoform of human prostate secretory protein (PSP-94) with potential anti-metastasis
and anti-angiogenesis activities. PSP-94-derived peptide PCK3145 may inhibit the secretion
of the metastasis-related protein matrix metalloproteinase-9 (MMP-9) and its potential
binding to its cell surface receptor CD44; may interfere with the vascular endothelial
growth factor (VEGF) signaling pathway, resulting in an anti-angiogenesis effect;
and may reduce the levels of parathyroid hormone-related protein (PTHrP), decreasing
plasma calcium levels. PSP-94, one of three predominant proteins found in seminal
fluid, may be down-regulated in prostate cancer, representing a potential survival
mechanism for prostate cancer cells. MMP-9 is implicated in the invasion and metastasis
of cancer. PTHrP may be expressed by various tumor cell types, resulting in the hypercalcemia
of malignancy.;
