Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

Macromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.

Genome‐wide screen reveals a universal role of ATP in ciprofloxacin tolerance among genetically distinct Escherichia coli persisters

mLife, EarlyView.
Abstract Bacterial persisters show tolerance to bactericidal antibiotics and play essential roles in chronic infections; however, the general mechanisms underlying persister formation and antibiotic tolerance remain insufficiently characterized. In this study, the Escherichia coli Keio library was used to identify genes involved in ciprofloxacin ...

Recent advances in noncanonical inhibition mechanisms of anti‐CRISPR proteins

mLife, EarlyView.
Abstract The CRISPR‐Cas system constitutes an adaptive immune mechanism in prokaryotes that defends against mobile genetic elements. Within the perpetual co‐evolutionary arms race between bacteria and their viral predators, bacteriophages encode anti‐CRISPR (Acr) proteins that use sophisticated molecular strategies to sabotage CRISPR‐Cas function ...

Harnessing Phytochemicals for Brain Cancer Therapy: Insights Into Medulloblastoma and Glioblastoma Treatment

Phytochemical Analysis, EarlyView.
ABSTRACT Primary brain tumors are life‐threatening diseases. Glioblastoma is the most aggressive type with a poor prognosis. Medulloblastoma is the most common pediatric brain tumor. While surgical treatments often result in recurrences owing to the complex nature of the tumor microenvironment, conventional treatments lower the quality of life of ...

A Feasibility Study of the Repurposing of Prazosin to Improve Treatment Outcomes in Men Receiving Radiotherapy for Prostate Cancer (MiniRaP‐00)

The Prostate, EarlyView.
ABSTRACT Background Further work is needed to improve treatment outcomes for prostate cancer (PCa), with the repurposing of the α1‐adrenoreceptor antagonists presenting a potential solution. This feasibility clinical trial presents the first prospective data of the use of an α1‐adrenoreceptor antagonist in men undergoing radiotherapy for PCa.

Nutritionally physiological cell culture medium and 3D culture influence breast tumour proteomics and anti-cancer drug effectiveness

Pharmacological Research
Many drugs have been discontinued during phase II/III breast cancer clinical trials due to lack of clinical efficacy, indicating shortcomings in predictive value of preclinical data.
