Poloxamer 188 (P188) was tested for effect on medullary hematopoiesis in aplastic anemia. P188 was administered to CBA mice with developing anemia via oral gavage at doses of 10, 100, and 500 mg/kg. A dose-dependent effect was observed, including an increase in erythrocyte count, hemoglobin, and reticulocyte count.

Near-infrared (NIR) controlled drug delivery systems have drawn a lot of attention throughout the past few decades due to the deep penetration depth and comparatively minor side effects of the stimulus. In this study, we introduce an innovative approach for gastric cancer treatment by combining photothermal infrared-sensitive gold nanorods (AuNRs) with a conjugated microporous polymer (CMP) to create a drug delivery system tailored for transporting the cytostatic drug 5-fluorouracil (5-FU). CMPs are fully conjugated networks with high internal surface areas that can be precisely tailored to the adsorption and transport of active compounds through the right choice of chemical functionalities.

There is major interest in deintensifying therapy for isocitrate dehydrogenase-mutant low-grade gliomas, including with single-agent cytostatic isocitrate dehydrogenase inhibitors. These efforts need head-to-head comparisons with proven modalities, such as chemoradiotherapy. Ongoing clinical trials now group tumors by intrinsic molecular subtype, rather than classic clinical risk factors.

Cancer is the leading cause of death from disease in children. Survival depends not only on surgery, cytostatic drugs, and radiation but also on systemic immune responses. Factors influencing these immune responses in children of different ages and tumor types are unknown.

Despite the enthusiasm for targeted cancer therapies in preclinical studies and the success of a select few drugs, many promising drug candidates fail in clinical trials. The gap between preclinical promise and clinical outcomes underscores the need to investigate factors influencing the success or failure of targeted therapies. Dasatinib, an inhibitor of Abl and Src protein tyrosine kinases, is highly effective toward chronic myeloid leukemia (CML) by targeting BCR-Abl, but it is ineffective against solid tumors when targeting Src kinases.
