In Vivo Direct Reprogramming: Current Progress and Future Prospects from Mechanisms to Therapeutic Application

Advanced Science, EarlyView.
This review examines the potential of in vivo direct reprogramming in regenerative medicine for functional tissue restoration, highlighting the role of tissue‐resident cues in generating functionally mature reprogrammed cells from lineage‐related cells. It contains a discussion on mechanisms, reprogramming factors, delivery approaches, and applications

In vitro dynamics of DNA loop extrusion by structural maintenance of chromosomes complexes

Current Opinion in Genetics & Development
Genomic DNA inside the cell's nucleus is highly organized and tightly controlled by the structural maintenance of chromosomes (SMC) protein complexes. These complexes fold genomes by creating and processively enlarging loops, a process called loop extrusion.

Natural Product Toosendanin Suppresses the Malignant Development of Skin Melanoma by Targeting BNC2 for Degradation

Advanced Science, EarlyView.
BNC2 exhibits context‐dependent opposing functions across multiple cancer types. This study reveals BNC2 as an oncogenic driver of melanoma proliferation and metastasis through transcriptional activation of PIK3CA. The natural compound TSN simultaneously degrades BNC2 and its oncogenic partner SMAD3 via CRBN‐dependent ubiquitination.

Multifunctional Nanovaccine‐Radiotherapy Synergy Drives Anti‐Tumor Immunity via Multi‐Cascade Cell Death for Pancreatic Cancer Therapy

Advanced Science, EarlyView.
Machine‐learning‐driven transcriptomic analysis identifies FSTL3 as a key tumor‐microenvironment regulator in desmoplastic pancreatic adenocarcinoma. A cRGD‐modified liposome co‐loading gemcitabine and siFSTL3 serves as an irradiation‐triggered in situ nanovaccine. It synergizes with radiotherapy to induce ferroptosis and immunogenic cell death through

High-resolution CTCF footprinting reveals impact of chromatin state on cohesin extrusion

Nature Communications
Cohesin-mediated DNA loop extrusion enables gene regulation by distal enhancers through the establishment of chromosome structure and long-range enhancer-promoter interactions.

Cohesin mutations alter DNA damage repair and chromatin structure and create therapeutic vulnerabilities in MDS/AML

JCI Insight, 2021
The cohesin complex plays an essential role in chromosome maintenance and transcriptional regulation. Recurrent somatic mutations in the cohesin complex are frequent genetic drivers in cancer, including myelodysplastic syndromes (MDS) and acute myeloid ...

Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease

Advanced Science, EarlyView.
A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

Diffusion of activated ATM explains γH2AX and MDC1 spread beyond the DNA damage site

iScience
Summary: During DNA repair, ATM-induced H2AX histone phosphorylation and MDC1 recruitment spread megabases beyond the damage site. While loop extrusion has been suggested to drive this spread, the underlying mechanism remains unclear.

Computational prediction of CTCF/cohesin-based intra-TAD loops that insulate chromatin contacts and gene expression in mouse liver

eLife, 2018
CTCF and cohesin are key drivers of 3D-nuclear organization, anchoring the megabase-scale Topologically Associating Domains (TADs) that segment the genome.
