Oligodendrocytes are sensitive to ischemic damage. The Sonic hedgehog (Shh) pathway is critical in oligodendrogenesis; Gli1 is the principal effector of Shh signaling. We investigated oligodendrogenesis and Shh/Gli1 pathway activation after bone marrow stromal cell (BMSC) treatment of stroke in rats. Rats were subjected to the middle cerebral artery occlusion (MCAo). BMSCs have been shown to pr...

The up-regulation of chemokine receptors CXCR4 and CXCR7 impacts on the distant metastasis and prognosis of breast cancer, though knowledge about the regulatory mechanism of their expressions is limited. Meanwhile, the GLI transcription factors of Hedgehog signaling have been reported to play a pivotal role in the development and progression of many types of human cancer. In breast cancer, the ...

The data presented in this article support the accompanying research article "Identification of a DYRK1A-mediated phosphorylation site within the nuclear localization sequence of the hedgehog transcription factor GLI1" (Ehe et al., 2017) [1]. Although it has been demonstrated that DYRK1A (dual-specificity tyrosine-regulated kinase 1A) can phosphorylate the hedgehog pathway transcription factor ...

The aim of the present study was to analyze the mrna and protein expression of glioma-associated oncogene 1 (Gli1) in hepatocellular carcinoma (Hcc) and its correlation with sonic hedgehog (Shh), one of the ligands of hedgehog (Hh) signaling, and two epithelial-mesenchymal transition (eMT) markers, e-cadherin and S100a4. We also investigated the potential crosstalk between Hh signaling and eMT ...

Hedgehog (Hh) signaling and the pyruvate kinase isoenzyme M2 (PKM2 or M2-PK) are often involved in tumorigenesis and growth. Aberrant activation of Hh signaling is found in a variety of malignancies. In tumor cells, PKM2 determines whether glucose is used for the synthesis of cellular building blocks or the production of lactate for energy regeneration; it associated with the Warburg effect. Gl...

Hedgehog signaling is essential for tissue development and stemness, and its deregulation has been observed in many tumors. Aberrant activation of Hedgehog signaling is the result of genetic mutations of pathway components or other Smo-dependent or independent mechanisms, all triggering the downstream effector Gli1. For this reason, understanding the poorly elucidated mechanism of Gli1-mediated...

OBJECTIVE The aim of this study was to investigate the expression and clinical significance of Gli1 and Wnt2B in pancreatic cancer. METHODS We have constructed a formalin-fixed paraffin embedded pancreatic tissue microarrays 180 cylindrical tissue cores of human pancreatic cancer and its paracancerous nonmalignant pancreatic specimens (NMPs) from 90 patients. Levels of Gli1 and Wnt2B were mea...

Genistein is an isoflavone from soy with multiple action targets in cellular processes. Hedgehog signaling and its activator Gli1 are involved not only in oncogenesis, but also in cancer stemness and overexpression of CD44, a typical cancer stem cell surface marker. It has been shown that levels of Gli1 and CD44 expression are downregulated by genistein. Genistein may modulate distinctive cellu...

Normally, sonic hedgehog (Shh) signaling induces high levels of Patched 1 (Ptc1) and its associated transcription factor Gli1 with genesis of specific neuronal progeny. But their roles in the neural stem cells (NSCs), including glial precursor cells (GPCs), of Alzheimer’s disease (AD) are unclear. Here, we show that Ptc1 and Gli1 are significantly deficits in the hippocampus of an aged AD trans...

Local control and overall survival in patients with advanced head and neck squamous cell cancer (HNSCC) remains dismal. Signaling through the Hedgehog (Hh) pathway is associated with epithelial-to-mesenchymal transition, and activation of the Hh effector transcription factor Gli1 is a poor prognostic factor in this disease setting. Here, we report that increased GLI1 expression in the leading e...
