prostasomes
Prostasomes are large protein complexes found in the cytoplasm of eukaryotic cells, particularly in the prostate gland. They were first identified in the 1990s and are named for their association with the prostate-specific antigen (PSA), a protein commonly used as a biomarker for prostate cancer. Prostasomes are involved in various cellular processes, including protein degradation, DNA repair, and cell signaling. They are composed of multiple subunits, including PSA, and are thought to play a role in maintaining cellular homeostasis and protecting against cellular damage. Recent research has suggested that prostasomes may also be involved in the development and progression of prostate cancer, although the exact mechanisms are not yet fully understood. Further studies are needed to elucidate the precise functions of prostasomes and their potential as therapeutic targets in prostate cancer.
