The present disclosure provides methods for treating prostate cancer or metastatic castration-resistant prostate cancer, reducing the severity of prostate cancer or metastatic castration-resistant prostate cancer, or inhibiting the growth of prostate cancer or metastatic castration-resistant prostate cancer. The methods of the present disclosure comprise administering to a subject in need thereof a therapeutically effective amount of a bispecific antibody, or antigen-binding fragment thereof, that specifically binds to prostate specific membrane antigen (PSMA) and CD28, as a monotherapy or in combination with an anti-PD1 antibody.

The present invention relates to a composition for the treatment of castration resistant prostate cancer, the composition comprising (i) a first active ingredient comprising a CDK9 degrading agent; and (ii) a second active ingredient, wherein the second active ingredient comprises olaparib. The effects of inhibiting tumor cell proliferation and promoting cell apoptosis of the composition are obviously higher than those of a single drug under the same dosage.

Downregulated miR-99b-5p and upregulated mTOR cooperatively promotes the African American (AA) PCa aggressiveness and drug resistance. Nuclear mTOR, AR, and SMARCD1 are highly expressed in AA PCa (MDA PCa 2b) compared to EA PCa (LNCaP) cell line. miR-99b-5p inhibited protein levels of mTOR, AR / AR-V7 and SMARCD1 in cytoplasm and nuclei of EA and AA PCa. miR-99b-5p effectively inhibits cell proliferation / survival and induced cell apoptosis in EA and AA PCa cells. Moreover, combination of miR-99b-5p and enzalutamide (Enz) synergistically enhances the cytotoxicity against aggressive AA PCa and castration resistant prostate cancer (CRPC). miR-99b-5p or miR-99b-5p / Enz significantly reduces the recruitment of mTOR to the genes involved in the metabolic reprogramming in CRPC. miR-99b-5p can function as an epigenomic driver to modulate the mTOR / AR / SMARCD1 signaling axis in AA PCa and resistant CRPC. miR-99b-5p can be utilized as a biomarker for identifying the presence of prostate cancer.

Embodiments of the invention are directed to the treatment of subjects with prostate cancer, in particular those with castration resistant prostate cancer, with glucocorticoid receptor antagonists. The prostate cancer may be one that has become resistant to androgen deprivation therapy, for example, by increase in glucocorticoid receptor expression and / or activity.

Disclosed herein are methods and uses of the polypharmacological modulator SR1903 and related compounds for inhibiting triggering receptor expressed on myeloid cells-1 (TREM-1) and treating diseases and conditions that are related to or mediated by TREM-1, such as inflammatory diseases, autoimmune diseases, metabolic disorders, and castration resistant prostate cancer (CRPC).

The invention relates to the technical field of nano material preparation, in particular to spine-shaped zinc oxide nanoparticles and a preparation method and application thereof.The preparation method comprises the steps that green tea extract powder is subjected to gamma-ray irradiation treatment, green tea polyphenol obtained through extraction treatment is mixed with a zinc source and an alkali solution, the pH is adjusted, and precipitates are obtained after a reaction; and calcining the precipitate to obtain the spine-shaped zinc oxide nanoparticles. Green tea polyphenol is obtained from the green tea extract powder subjected to gamma-ray irradiation treatment and serves as a reducing agent and a stabilizing agent; the green tea polyphenol reacts with a zinc source, so that the spine-shaped ZnO nanoparticles are synthesized in a green manner. The zinc oxide nanoparticle prepared by the preparation method has a spine-shaped structure and good crystallinity, the median inhibitory concentration of the zinc oxide nanoparticle in a castration resistant type prostate cancer cell line is obviously lower than that of a hormone sensitive type prostate cancer cell line, and the zinc oxide nanoparticle shows a more obvious cytotoxic effect on invasive prostate cancer.
