Gold nanorod-based engineered nanogels for cascade-amplifying photothermo-enzymatic synergistic therapy.

Reactive oxygen species (ROS)-mediated anticancer modalities, which disturb the redox balance of cancer cells through multi-pathway simulations, hold great promise for effective cancer management. Among these, cooperative physical and biochemical activation strategies have attracted increasing attention because of their spatiotemporal controllability, low toxicity, and high therapeutic efficacy. Herein, we demonstrate a nanogel complex as a multilevel ROS-producing system by integrating chloroperoxidase (CPO) into gold nanorod (AuNR)-based nanogels (ANGs) for cascade-amplifying photothermal-enzymatic synergistic tumor therapy.

Catalytic-independent functions of the Integrator-PP2A complex (INTAC) confer sensitivity to BET inhibition.

Chromatin and transcription regulators are critical to defining cell identity through shaping epigenetic and transcriptional landscapes, with their misregulation being closely linked to oncogenesis. Pharmacologically targeting these regulators, particularly the transcription-activating BET proteins, has emerged as a promising approach in cancer therapy, yet intrinsic or acquired resistance frequently occurs, with poorly understood mechanisms. Here, using genome-wide CRISPR screens, we find that BET inhibitor efficacy in mediating transcriptional silencing and growth inhibition depends on the auxiliary/arm/tail module of the Integrator-PP2A complex (INTAC), a global regulator of RNA polymerase II pause-release dynamics.

FDG PET/CT in a Case of Metastasizing Pleomorphic Adenoma in the Ilium.

Although pleomorphic adenomas of the salivary glands are benign tumors, they can metastasize to distant organs without evidence of malignant transformation. We describe FDG PET/CT finding in a case of metastasizing pleomorphic adenoma in the right ilium occurring 22 years after initial surgical resection of a lip pleomorphic adenoma. On FDG PET/CT, the iliac metastasis appeared as an expansile osteolytic lesion with heterogeneous activity.

Surface enzyme-polymerization endows Janus hydrogel tough adhesion and regenerative repair in penetrating orocutaneous fistulas.

Penetrating orocutaneous or oropharyngeal fistulas (POFs), severe complications following unsuccessful oral or oropharyngeal reconstruction, remain complex clinical challenges due to lack of supportive tissue, contamination with saliva and chewed food, and dynamic oral environment. Here, we present a Janus hydrogel adhesive (JHA) with asymmetric functions on opposite sides fabricated via a facile surface enzyme-initiated polymerization (SEIP) approach, which self-entraps surface water and blood within an in-situ formed hydrogel layer (RL) to effectively bridge biological tissues with a supporting hydrogel (SL), achieving superior wet-adhesion and seamless wound plugging. The tough SL hydrogel interlocked with RL dissipates energy to withstand external mechanical stimuli from continuous oral motions like chewing and swallowing, thus reducing stress-induced damage.
