Role of lamins in 3D genome organization and global gene expression
Nucleus, 2019 Genome-wide mapping of lamin-B1-genome interactions has shown that gene-poor and transcriptionally inactive genomic regions are associated with the nuclear lamina.

Filament assembly of the C. elegans lamin in the absence of helix 1A
Nucleus, 2022 Lamins are the major constituent of the nuclear lamina, a protein meshwork underlying the inner nuclear membrane. Nuclear lamins are type V intermediate filaments that assemble into ~3.5 nm thick filaments.

Advanced Science, EarlyView.CTSK plays a critical role in pulmonary fibrosis. Excessive CTSK accumulation interacts with SNX9 to enhance TGF‐β1‐induced SMAD3 activation and GLS1 expression in fibroblasts, driving glutamine metabolism for collagen biosynthesis and exacerbating pulmonary fibrosis.

Regulation of diverse nuclear shapes: pathways working independently, together
Communicative & Integrative Biology, 2021 Membrane-bound organelles provide physical and functional compartmentalization of biological processes in eukaryotic cells. The characteristic shape and internal organization of these organelles is determined by a combination of multiple internal and ...

European Journal of Applied Mathematics, 1993 This paper deals with the mathematical characterization of microstructure in elastic solids. We formulate our ideas in terms of rank-one convexity and identify the set of probability measures for which Jensen's inequality for this type of functions holds. This is the set of laminates.

Advanced Science, EarlyView.The study identifies a novel circular RNA derived from the TP53 gene (circTP53), which is upregulated in HNSCC and correlates with poor patient prognosis. It demonstrates that circTP53 promotes HNSCC progression by interacting with USP10, stabilizing both proteins, enhancing deubiquitination of p53, and thereby influencing tumor growth, with its ...

Advanced Science, EarlyView.This study identifies ARID1B as a chromatin‐bound driver of tumor growth in TNBC. ARID1B impairs ARID1A function and directly activates oncogenic programs through SWI/SNF remodeling. Its nuclear localization, mediated by the KPNA2–KPNB1–RANBP2 import machinery, is essential for its tumor‐promoting activity.

Nuclear Actin and Lamins in Viral Infections
Viruses, 2012 Lamins are the best characterized cytoskeletal components of the cell nucleus that help to maintain the nuclear shape and participate in diverse nuclear processes including replication or transcription.

Advanced Science, EarlyView.In the study, UBE2C was found to be significantly overexpressed in breast cancer and transcriptionally regulated by FOXM1. Inhibition of UBE2C suppressed proliferation, induced senescence, and sensitized breast cancer cells to doxorubicin. Mechanistically, UBE2C inhibition promoted Parkin‐mediated K63‐linked ubiquitination of TOP2A.
