Human Telomeres Are Tethered to the Nuclear Envelope during Postmitotic Nuclear Assembly

Cell Reports, 2012
Telomeres are essential for nuclear organization in yeast and during meiosis in mice. Exploring telomere dynamics in living human cells by advanced time-lapse confocal microscopy allowed us to evaluate the spatial distribution of telomeres within the ...

Telomeres reforged with non-telomeric sequences in mouse embryonic stem cells

Nature Communications, 2021
Telomeres can be maintained by a telomerase-independent mechanism called an alternative lengthening of telomeres (ALT). Here the authors use mouse Terc (telomerase RNA) knockout embryonic cells and provide longitudinal analysis of ALT telomeres ...

A dsRNA Viral Transcriptional Regulator Evades Innate Immunity by Hijacking Host CoTranscription Factor DHX9

Advanced Science, EarlyView.
This study identifies a new viral mechanism by a viral protein σ3 that functions as a vTR to suppress NF‐κB gene expression via its direct interaction with the host helicase DHX9. Through their interaction, σ3 not only impairs the initial recruitment of Pol II but also affects Pol II pause‐release and ultimately suppresses NF‐κB gene expression ...

Quantitative Proteomics and CRISPR/Cas9 Editing Reveal UPR‐Mediated Control of Immunoglobulin Homeostasis in Hybridomas

Advanced Science, EarlyView.
BCR sequencing and subclone analysis correlated immunoglobulin (Ig) chain loss in dysfunctional hybridomas with disrupted monoclonal antibody homeostasis. Proteomics‐guided CRISPR/Cas9 editing revealed that the unfolded protein response (UPR) regulates aberrant Ig synthesis.

Reference‐Guided Chromosome‐by‐Chromosome de novo Assembly at Scale Using Low‐Coverage High‐Fidelity Long‐Reads with HiFiCCL

Advanced Science, EarlyView.
HiFiCCL, as the first assembly framework specifically designed for low‐coverage high‐fidelity reads, improves the assembly quality of existing assemblers and also enhances downstream applications such as large structural variant (SV) detection (>10 000 bp), synteny analysis, pangenome graph construction, and graph‐based individual‐specific germline SVs

EGR Proteins Mediate Interferon‐Independent Anti‐HSV‐1 Responses Through Viral and Host Targets

Advanced Science, EarlyView.
Early antiviral responses are typically mediated by interferons. However, during HSV‐1 infection, host early growth response (Egr) genes, which are not interferon‐stimulated genes, are quickly induced by viral protein ICP0. EGR proteins, in turn, suppress viral lytic infection by activating viral latency‐associated (LAT) and host immune regulatory ...

Renal fibroblasts are involved in fibrogenic changes in kidney fibrosis associated with dysfunctional telomeres

Experimental and Molecular Medicine
Tubulointerstitial fibrosis associated with chronic kidney disease (CKD) represents a global health care problem. We previously reported that short and dysfunctional telomeres lead to interstitial renal fibrosis; however, the cell-of-origin of kidney ...

A Programmable Nanoreactor Orchestrates Cascade of DNA Sensing to Amplify cGAS‐STING Activation for Cancer Immunotherapy

Advanced Science, EarlyView.
A programmable nanoreactor was engineered for precise cGAS‐STING pathway activation in cancer immunotherapy. This strategy bridges targeted tumor DNA damage with DC immunomodulation, providing a translatable platform to unlock innate and adaptive antitumor immunity.

A Sirtuin‐1‐Targeted Gene‐Activating Tetrahedral DNA Attenuates Bladder Fibrosis by Restoring Mitophagy in Fibroblasts via the SIRT1‐FOXO3‐BNIP3 Axis

Advanced Science, EarlyView.
The SIRT1‐targeted saRNA‐delivering tetrahedral DNA (TSA) treatment effectively upregulates SIRT1 expression, which subsequently promotes FOXO3A deacetylation. This deacetylation event relieves FOXO3A's transcriptional repression on the BNIP3 gene, thereby initiating PINK1‐PARKIN‐dependent mitophagy.

Engineering Immune Cell to Counteract Aging and Aging‐Associated Diseases

Advanced Science, EarlyView.
This review highlights a paradigm shift in which advanced immune cell therapies, initially developed for cancer, are now being harnessed to combat aging. By engineering immune cells to selectively clear senescent cells and remodel pro‐inflammatory tissue microenvironments, these strategies offer a novel and powerful approach to delay age‐related ...
