Special Issue Information

Dear Colleagues,

Prostate cancer is the second leading cause of cancer-related death globally. Thus, patients with locally advanced or metastatic stages of cancer have been the focus of recent research. Emerging insights and an increased understanding of prostate cancer tumor biology have demonstrated that the concept of ‘one size fits all’ does not account for locally advanced or metastatic prostate cancer patients.

In locally advanced prostate cancer, precise staging and consequently, allocating the patient the most beneficial treatment, represents an ongoing field of interest. In particular, selecting the most appropriate multimodal treatment according to the patient’s specific risk level is of utmost importance to establish a balance between adequate cancer control and preventing overtreatment and its associated side effects.

For metastatic prostate cancer patients, treatment decision is becoming increasingly sophisticated and can be tailored to both hormone-sensitive and castration-resistant diseases. Substantial efforts in the recent past have gone towards unscrambling sequences and the most efficient combination of systemic-acting treatment regimens (including androgen deprivation, novel secondary hormonal therapy, chemotherapy); in addition, surgical and radiation treatments result in the most beneficial survival outcome. Moreover, the application of of PARP inhibitors in castration-resistant patients has further expanded the therapeutic armamentarium. 

For this Special Issue, we are inviting research which focuses on diagnostic and treatment pathways for locally advanced and metastatic prostate cancer patients. Both original articles and reviewers are welcome. Potential and exciting research areas may include (but are not limited to) the following: prostate cancer, (oligo-)metastatic disease, chemotherapy, hormonal therapy, targeted therapy, metastasis-directed treatment, PARP, and sequencing.

We look forward to receiving your submission.

Background: Radiotherapy constitutes an important therapeutic option for prostate cancer. However, prostate cancer cells often acquire resistance during cancer progression, limiting the cytotoxic effects of radiotherapy. Among factors regulating sensitivity to radiotherapy are members of the Bcl-2 protein family, known to regulate apoptosis at the mitochondrial level. Here, we analyzed the role of anti-apoptotic Mcl-1 and USP9x, a deubiquitinase stabilizing Mcl-1 protein levels, in prostate cancer progression and response to radiotherapy. Methods: Changes in Mcl-1 and USP9x levels during prostate cancer progression were determined by immunohistochemistry. Neutralization of Mcl-1 and USP9x was achieved by siRNA-mediated knockdown. We analyzed Mcl-1 stability after translational inhibition by cycloheximide. Cell death was determined by flow cytometry using an exclusion assay of mitochondrial membrane potential-sensitive dye. Changes in the clonogenic potential were examined by colony formation assay. Results: Protein levels of Mcl-1 and USP9x increased during prostate cancer progression, and high protein levels correlated with advanced prostate cancer stages. The stability of Mcl-1 reflected Mcl-1 protein levels in LNCaP and PC3 prostate cancer cells. Moreover, radiotherapy itself affected Mcl-1 protein turnover in prostate cancer cells. Particularly in LNCaP cells, the knockdown of USP9x expression reduced Mcl-1 protein levels and increased sensitivity to radiotherapy. Conclusion: Posttranslational regulation of protein stability was often responsible for high protein levels of Mcl-1. Moreover, we demonstrated that deubiquitinase USP9x as a factor regulating Mcl-1 levels in prostate cancer cells, thus limiting cytotoxic response to radiotherapy. Full article
