PSAP (Prostatic Acid Phosphatase)

Optical biosensing technologies represent a transformative approach to phosphatase detection, enabling real-time monitoring and predictive analytics in precision diagnostics. Their integration into clinical workflows could facilitate early disease detection, personalized treatment strategies, and improved patient outcomes.

Despite the addition of multiple life-prolonging therapeutic modalities now available to treat patients with mCRPC, the mechanism of action of sipuleucel-T remains unique for patients with advanced prostate cancer. Therefore, maximizing the appropriate clinical utilization of sipuleucel-T in patients with mCRPC within current treatment paradigms is essential.

Collectively, these mechanisms characterise the plasma membrane as a dynamic metabolic interface, where oxygen sensing coordinates adenosine and phosphate turnover, thereby promoting tumour adaptation across hypoxic environments. We propose that hypoxia orchestrates a dual regulatory loop connecting adenosine accumulation and phosphate turnover at the tumour cell surface, providing a conceptual basis for future mechanistic studies.

[68Ga]Ga-OncoACP3-DOTA changed therapeutic management in three of six patients with biochemical recurrence, and in two of 12 patients with known metastases. Although the retrospective comparison is potentially biased, the intense and reliable tumor uptake and the low off-target activity of OncoACP3-DOTA provide a strong rationale for future exploration in trials on PET imaging and radioligand therapy with β- and α-particle emitters.

We previously reported a clinical trial (NCT02499835) evaluating PD-1 blockade combined with an anti-tumor DNA vaccine, pTVG-HP (encoding prostatic acid phosphatase), in patients with metastatic castration-resistant prostate cancer...These findings suggest that patients experiencing irAEs can have immune responses to tumor irrespective of obvious anti-tumor efficacy, at least with these treatments, and underscore the importance of tumor-infiltrating professional antigen presenting cells and T-cell activation for successful immunotherapy. Moreover, our findings suggest that combining vaccines and PD-1 blockade with MDSC-targeting therapies, anti-VISTA, and/or anti-PARP therapies might be further explored.

Given the use of sipuleucel-T as a standard of care backbone, there is emerging interest in combining it with other immunotherapies, hormonal therapies, or chemotherapies to improve its clinical efficacy. This review summarizes past experiences and current knowledge of combining sipuleucel-T with other treatments and explores future approaches to enhance such combinatorial strategies.

IIL-1β polymorphism, particularly the AA genotype, is associated with increased PSA levels, larger prostate volume, and more aggressive prostate cancer phenotypes. These findings underscore the potential of IL-1β genotyping as a biomarker for prostate cancer severity and progression.

Selected clones bound with high specificity to the cognate target and demonstrated excellent tumor-targeting performance in biodistribution studies. The lead candidates, termed H92A5 (anti-PSMA) and EKA4 (anti-ACP3), could serve as promising scaffolds for the development of next-generation tumor-targeted therapeutics for prostate cancer.

Notably, the co-administration of ACP-3 with cyclophosphamide (CTX) could synergistically enhance antitumor activity and concurrently alleviate CTX-induced adverse effects such as weight loss, hepatorenal toxicity, and immune dysfunction. These findings collectively establish ACP-3 as a promising therapeutic candidate for the treatment of HCC.
