Superlattice materials offer new opportunities to modify optical and electrical properties of recently emerging 2D materials. The insertion of tetraethylbenzidine (EtDAB) into interlamination of the established 2D PbI2 semiconductor through a mild solution method yielded the first lead iodide superlattice, EtDAB⋅4PbI2 (EtDAB=tetraethylbenzidine), with radical and non‐radical forms. The non‐radical form has a non‐ionic structure that differs from the common ionic structures for inorganic–organic hybrid lead halides. The radical form shows five orders of magnitude greater conductance and broader photoconductive response range (UV/Vis → UV/Vis‐IR), than pure PbI2 and the non‐radical form of the superlattice.

Two new coordination polymers {[Zn(L)(dma)] 2 ·H 2 O} n (1) and {[Cd(L)(H 2 O) 3 ]·dma·H 2 O} n (2) {H 2 L = 5-[(pyren-9-ylmethyl)amino]isophthalic acid, dma = N,N-dimethylacetamide} were synthesized by the reaction of H 2 L and zinc(II) or cadmium(II) nitrate in mixed solvents. Single-crystal XRD analyses show that polymers 1 and 2 have 1D chain structures. Due to [a]

Colorectal cancer (CRC) is a global health concern. The role of epigenetics in tumors has garnered increasing interest. ADP ribosylation is an epigenetic modification that is associated with a variety of biological functions and diseases, and its association with tumor development and progression has been hypothesized. However, due to the limitations of available techniques and methods, ADP ribosylation of specific sites is difficult to determine. In previous studies, it was shown that arginine-117 of histone 3 (H3R117) in Lovo cells can be modified by mono-ADP-ribosylation. This site was mutated and Lovo cells overexpressing this mutant construct were established. In the present study, the expression of differentially expressed genes (DEGs) between untransfected Lovo cells and H3R117A Lovo cells was analyzed. A total of 58,174 DEGs were identified, of which 2,324 were significantly differentially expressed (q-value <0.05; fold change >2). Functional annotation and Kyoto Encyclopedia of Genes and Genomes pathway enrichment was used to analyze the functions and possible roles of the DEGs. The DEGs were enriched in pathways associated with metabolic process, catalytic activity, organelle and chromatin structure, and dynamics. Through this comprehensive and systematic analysis, the role of mono-ADP-ribosylation in CRC was examined, providing a foundation for future studies.
