Stalled replication forks, susceptible to nucleolytic threats, necessitate protective mechanisms involving pivotal factors such as the tumor suppressors BRCA1 and BRCA2. Here, we demonstrate that, upon replication stress, RNA polymerase II (RNAPII) is recruited to stalled forks, actively promoting the transient formation of RNA-DNA hybrids. These hybrids act as safeguards, preventing premature engagement by the DNA2 nuclease and uncontrolled DNA2-mediated degradation of nascent DNA.

Immune exclusion inhibits anti-tumor immunity and response to immunotherapy, but its mechanisms remain poorly defined. Here, we demonstrate that Trophoblast Cell-Surface Antigen 2 (TROP2), a key target of emerging anti-cancer Antibody Drug Conjugates (ADCs), controls barrier-mediated immune exclusion in Triple-Negative Breast Cancer (TNBC) through Claudin 7 association and tight junction regulation. TROP2 expression is inversely correlated with T cell infiltration and strongly associated with outcomes in TNBC.

Limited flexibility, complex manufacturing processes, high costs, and insufficient performance are major factors restricting the scalability and commercialization of flexible inorganic thermoelectrics for wearable electronics and other high-end cooling applications. We developed an innovative, cost-effective technology that integrates solvothermal, screen-printing, and sintering techniques to produce an inorganic flexible thermoelectric film. Our printable film, comprising BiTe-based nanoplates as highly orientated grains and Te nanorods as "nanobinders," shows excellent thermoelectric performance for printable films, good flexibility, large-scale manufacturability, and low cost.

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive subtype of peripheral T-cell lymphoma (PTCL) characterized by its T-follicular helper (TFH) phenotype. Relapsed and refractory disease is common in AITL and often associated with a poor prognosis. The presence of epigenetic abnormalities, immune dysregulation, hyperinflammation and active angiogenesis in AITL offers potential targets for histone deacetylase (HDAC) inhibitors and immunomodulatory drugs (IMiDs).

Combining chemical oxidation and adsorption is highly desirable but challenging to remove organoarsenic compounds for water purification. Herein, we prepared a Zn-doped CuO (CuZnO-2) catalyst by incorporating Zn atoms into the CuO lattice, which results in abundant surface oxygen vacancies (OVs) and modulates the electronic structure of Cu-OVs-Zn sites for PMS activation to degrade p-arsanilic acid (p-ASA) and adsorb the secondary arsenic species simultaneously. The elevated d-band centers for Cu upward to the Fermi level can significantly strengthen the adsorption of PMS, p-ASA, and the generated arsenic species.

Sphingolipids, particularly sphingosine-1-phosphate (S1P), are bioactive lipids involved in regulating cellular processes such as proliferation, apoptosis, inflammation, and tumor progression. Alkaline ceramidase 2 (ACER2) plays a critical role in sphingolipid metabolism by catalyzing the hydrolysis of ceramide to sphingosine, which is subsequently converted to S1P. Dysregulation of ACER2 has been implicated in various gastrointestinal cancers, including colorectal cancer, gastric cancer, and hepatocellular carcinoma.

To efficiently remove micropollutants from drinking water, this study developed an adsorption-enhanced Fenton catalytic membrane with a two-dimensional structure composed of graphene oxide loaded with iron-cyclodextrin metal-organic frameworks (FeCD-MOF). As water passes through the interlayer channels, micropollutants and hydrogen peroxide (HO) are adsorbed into the voids of the FeCD-MOF and the cavities of the CD. This process increases the concentration of micropollutants and HO in the confined space, thereby significantly enhancing the efficiency of the Fenton catalytic reaction.
