Anillin (ANLN), a mitotic protein that regulates contractile ring assembly, has been reported as an oncoprotein. However, the function of ANLN in cancer cells, especially in the nucleus, has not been fully understood. Here, we report a role of nuclear ANLN in gene transcriptional regulation. We find that nuclear ANLN directly interacts with the RNA polymerase II (Pol II) large subunit to form transcriptional condensates. ANLN enhances initiated Pol II clustering and promotes Pol II CTD phase separation. Short-term depletion of ANLN alters the chromatin binding and enhancer-mediated transcriptional activity of Pol II. The target genes of ANLN-Pol II axis are involved in oxidoreductase activity, Wnt signaling and cell differentiation. THZ1, a super-enhancer inhibitor, specifically inhibits ANLN-Pol II clustering, target gene expression and esophageal squamous cell carcinoma (ESCC) cell proliferation. Our results reveal the function of nuclear ANLN in transcriptional regulation, providing a theoretical basis for ESCC treatment.

2,9-Diamide-1,10-phenanthroline (DAPhen) extractants constitute a novel class of tetradentate agents due to their high affinity for actinides and their adherence to the CHON principle. In this investigation, we explored the performance in extraction and the capabilities for An/Ln separation of a series of ,'-diethyl-,'-diethyl-2,9-diamide-1,10-phenanthroline (Et-Et-DAPhen), ,'-dioctyl-,'-dioctyl-2,9-diamide-1,10-phenanthroline (Oct-Oct-DAPhen), ,'-diethyl-,'-ditolyl-2,9-diamide-1,10-phenanthroline (Et-Tol-DAPhen), and ,'-dialkyl-,'-diphenyl-2,9-diamide-1,10-phenanthroline (R-Ph-DAPhen, R = H, Me, Et, Oct) extractants featuring diverse amide substituents. Combining extraction experiments with theoretical calculations reveals that substituting ethyl with octyl enhances the extraction efficiency.

Advanced used nuclear fuel (UNF) reprocessing strategies are limited by the complex radiochemical separations and engineering required to achieve the separation of actinides (An) from neutron scavenging lanthanides (Ln). The accessibility of the hexavalent oxidation state for the actinides (U - Am) provides a pathway to achieving a group hexavalent actinide separation from the trivalent lanthanides and Cm. The solid oxidant and ion exchanger, sodium bismuthate (NaBiO), has been demonstrated to quantitatively oxidize and separate Am from trivalent Cm in a column chromatographic system.

Mammalian cardiomyocytes become terminally-differentiated during the perinatal period. In rodents, cytokinesis ceases after a final division cycle immediately after birth. Nuclear division continues and most cardiomyocytes become binucleated by ∼11 days.

Background: Hepatocellular carcinoma (HCC) represents a primary liver tumor characterized by a bleak prognosis and elevated mortality rates, yet its precise molecular mechanisms have not been fully elucidated. This study uses advanced bioinformatics techniques to discern differentially expressed genes (DEGs) implicated in the pathogenesis of HCC. The primary objective is to discover novel biomarkers and potential therapeutic targets that can contribute to the advancement of HCC research.
