Article Synopsis
  • Radiotherapy for prostate cancer can lead to radioresistance, which involves cell adhesion signaling and changes in the protein composition of the cell-matrix junctions in cancer cells.
  • A mass spectrometry-based analysis compared radioresistant DU145 cells with their parental counterparts, revealing extensive matrix remodeling and altered protein expression, but no change in integrin levels.
  • Specific proteins, particularly perlecan/HSPG2, were found to play a crucial role in modulating radioresistance, suggesting that targeting this protein might offer new therapeutic strategies for treating prostate cancer.

Prostate cancer is among the top five cancer types according to incidence and mortality. One of the main obstacles in prostate cancer management is the inability to foresee its course, which ranges from slow growth throughout years that requires minimum or no intervention to highly aggressive disease that spreads quickly and resists treatment. Therefore, it is not surprising that numerous studies have attempted to find biomarkers of prostate cancer occurrence, risk stratification, therapy response, and patient outcome.

Prostate cancer is a heterogeneous disease, and one of the main obstacles in its management is the inability to foresee its course. Therefore, novel biomarkers are needed that will guide the treatment options. The extracellular matrix (ECM) is an important part of the tumor microenvironment that largely influences cell behavior.

Prostate cancer is among the leading cancers according to both incidence and mortality. Due to the high molecular, morphological and clinical heterogeneity, the course of prostate cancer ranges from slow growth that usually does not require immediate therapeutic intervention to aggressive and fatal disease that spreads quickly. However, currently available biomarkers cannot precisely predict the course of a disease, and novel strategies are needed to guide prostate cancer management.

Anticancer monotherapies are often insufficient in eradicating cancer cells because cancers are driven by changes in numerous genes and pathways. Combination anticancer therapies which aim to target several cancer traits at once represent a substantial improvement in anticancer treatment. Cisplatin is a conventional chemotherapy agent widely used in the treatment of different cancer types.
