Porcupine‐Quill‐Inspired Shape‐Morphing Biointerfaces Disassemble Biofilms

open access: yesAdvanced Science, EarlyView.
A porcupine‐spine‐inspired dynamic offensive bio‐interface is developed for active biofilm disassembly. By coupling electrically driven nano‐dagger penetration with light‐triggered ROS generation, the surface overcomes the passive limitations of conventional mechano‐bactericidal topographies, achieving near‐complete biofilm eradication, strong ...

Hedgehog Pathway Activation is Required in Small Cell Lung Cancer

open access: yes, 2011
Major finding: Hedgehog signaling underlies SCLC initiation, progression, and recurrence. Impact: Hedgehog pathway inhibitors may help prevent SCLC recurrence following chemotherapy.

Sacral Neural Crest‐Derived Extracellular Vesicles Promote Pelvic Ganglion Repair Through Anti‐Pyroptotic Effects Involving ANXA1–FPR2 Signaling

open access: yesAdvanced Science, EarlyView.
Extracellular vesicles derived from human pluripotent stem cell‐derived sacral neural crest cells promote repair of injured major pelvic ganglia and improve colorectal function. These vesicles reduce oxidative stress and pyroptosis, with ANXA1–FPR2 signaling contributing to their protective effects, and show a favorable therapeutic profile compared ...

Activation of the Hedgehog signaling pathway in T-lineage cells inhibits TCR repertoire selection in the thymus and peripheral T-cell activation [PDF]

open access: yes, 2007
TCR signal strength is involved in many cell fate decisions in the T-cell lineage. Here, we show that transcriptional events induced by Hedgehog (Hh) signaling reduced TCR signal strength in mice.

Sonic hedgehog pathway expression in non-small cell lung cancer

open access: yesTherapeutic Advances in Medical Oncology, 2012
Objective: Activation of the hedgehog pathway is an important signaling mechanism crucial in embryogenesis and has strong links to carcinogenesis. This study investigates the expression of the Sonic hedgehog pathway molecules in non-small cell lung ...

The emerging roles of phosphatases in Hedgehog pathway

open access: yesCell Communication and Signaling, 2017
Hedgehog signaling is evolutionarily conserved and plays a pivotal role in cell fate determination, embryonic development, and tissue renewal. As aberrant Hedgehog signaling is tightly associated with a broad range of human diseases, its activities must ...

The Characteristics of Tumor Microenvironment by the Single Cell Profile in Endometrial Cancer of no Specific Molecular Profile (NSMP) Subtype

open access: yesAdvanced Science, EarlyView.
A subset of tumor‐associated macrophages (TAMs) characterized by SPP1 expression is discovered, which may remodel the tumor microenvironment by potentially promoting CD4+ T cell stress and maintaining epithelial cell stemness through SPP1‐CD44, thereby potentially contributing to the proliferation and migration of tumor cells, which has been verified ...

Fish-specific duplicated dmrt2b contributes to a divergent function through Hedgehog pathway and maintains left-right asymmetry establishment function. [PDF]

open access: yes, 2009
Gene duplication is thought to provide raw material for functional divergence and innovation. Fish-specific dmrt2b has been identified as a duplicated gene of the dmrt2a/terra in fish genomes, but its function has remained unclear.

Inhibition of hedgehog pathway reveals the regulatory role of SMO in gastric cancer cells

open access: yesTumor Biology, 2017
Previous studies report aberrant activation of the hedgehog signaling pathway in the progression of various cancers. This study aimed to investigate the expressions of smoothened and downstream glioma-associated oncogene homology-1 in gastric cancer and ...

Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity

open access: yesAdvanced Science, EarlyView.
An acinar‐derived organoid system maintains adult pancreatic acinar identity ex vivo, converts it along an ordered acinar‐to‐ductal‐like trajectory, and then partially restores it. Each transition carries its own signal requirement, with EGF/EGFR initiating conversion and a staged glucocorticoid–IGF1R switch driving redifferentiation.
