Cancer stem cells (CSCs) contribute to the resistance of intractable prostate cancer, and dopamine receptor (DR)D2 antagonists exhibit anticancer activity against prostate cancer and CSCs. Human prostate cancer PC-3 cells were used to generate CSC-like cells, serving as a surrogate system to identify the specific DR subtype the inhibition of which significantly affects prostate-derived CSCs. Additionally, the present study aimed to determine the downstream signaling molecules of this DR subtype that exert more profound effects compared with other DR subtypes.

This study focuses on the synthesis, characterization, and evaluation of the photocatalytic efficiency of bismuth-based metal-organic frameworks (Bi-MOFs) and their derivatives, specifically Ag/Bi-MOF and NH /Ag/Bi-MOF, in the degradation of tetracycline (TC) and sulfamethoxazole (SMX) under visible light irradiation. Bi-MOFs are promising photocatalysts due to their large surface area, tunable porosity, and unique electronic properties that are favorable for visible light absorption. In this study, Bi-MOFs were synthesized using a solvothermal method, with the incorporation of silver (Ag) and ammonium (NH ) ions to enhance their photocatalytic performance.
