Background and aim: Basal cell carcinoma (BCC) is the most common cancer in humans. Activation of Hedgehog (Hh) signal has a key role in development of BCC. The end result of Hedgehog signal are Gli proteing. Gli 1 is a member of this family which activates DNA transcription. Previous studies showed increased expression of Gli 1 in BCC.Materials and methods: In this study 38 pathologic samples ...

Objective(s): The study aimed to investigate the effects of resveratrol on colorectal cancer HCT116 cells, including cell viability, apoptosis, and migration, and the partial mechanisms focused on hedgehog/gli-1 signaling pathways. Materials and Methods: We chose the appropriate time and concentration of recombinant human Sonic hedgehog (Shh) stimulation by cell viability. The proportion of cel...

OBJECTIVE To investigate the expression of glioma-associated oncogene homolog 1(Gli-1) in colon cancer and its association with clinicopathological parameters and postoperative liver metastasis. METHODS Expression of Gli-1 was detected by immunohistochemistry in paraffin-embedded specimens of 96 cases of colon cancer. Relationship between Gli-1 expression and clinicopathological parameters, p...

BACKGROUND Hedgehog (Hh) signaling, a vital signaling pathway for the development and homeostasis of vertebrate tissues, is mediated by members of the Gli family of zinc finger transcription factors. Hh signaling increases the transcriptional activity of Gli proteins, at least in part, by inhibiting their proteolytic processing. Conversely, phosphorylation by cAMP-dependent protein kinase (PKA)...

Several reports have indicated that hypoxia, GLI, and connective tissue growth factor (CTGF) contribute to pulmonary fibrosis in idiopathic pulmonary fibrosis. We investigated the participation of mitogen-activated protein kinase kinase (MEK) kinase 1 (MEKK1)/MEK1/ERK1/GLI-1/2 and activator protein-1 (AP-1) signaling in hypoxia-induced CTGF expression in human lung fibroblasts. Hypoxia time-dep...

In vertebrates, Hedgehog (Hh) signaling initiated in primary cilia activates the membrane protein Smoothened (Smo) and leads to activation of Gli proteins, the transcriptional effectors of the pathway. In the absence of signaling, Gli proteins are inhibited by the cytoplasmic protein Suppressor of Fused (SuFu). It is unclear how Hh activates Gli and whether it directly regulates SuFu. We find t...

Septate junctions (SJs) regulate paracellular permeability across invertebrate epithelia. However, little is known about the function of SJ proteins in aquatic invertebrates. In this study, a role for the transmembrane SJ protein gliotactin (Gli) in the osmoregulatory strategies of larval mosquito (Aedes aegypti) was examined. Differences in gli transcript abundance were observed between the mi...

Objective: To explore the expression of Shh signaling pathway factors in Gastrointestinal stromal tumor (GIST) tissues and their associations with clinical pathological factors. Methods: 129 GIST patient cases that underwent surgery treatment at the first affiliated hospital of Anhui Medical University from January 2001 to December 2008 and with complete records were collected. The expression o...

Sonic hedgehog (Shh) signaling is essential for many normal developmental processes. The Shh signal is interpreted by the Gli transcription factors. Elevated Gli-1 expression has been associated with several neoplasms, including basal cell carcinoma. All-trans retinoic acid (RA) has strong effects on epidermal growth and differentiation and has been used for the treatment of various epithelial ...
