Existing data suggest that proton pump inhibitors (PPIs), particularly omeprazole, have significant anti-tumor action in monotherapy and or combination chemotherapy. Hedgehog (Hh) signaling pathway represents a leading candidate as a molecular mediator of Barrett's esophagus (BE). Studies have indicated reduced miRNAs in BE progression, however, little is known about the latent anti-neoplasm ef...
Although breast cancer is one of the most common malignancies, the molecular mechanisms underlying its development and progression are not fully understood. To identify key molecules involved, we screened publicly available microarray datasets for genes differentially expressed between breast cancers and normal mammary glands. We found that three of the genes predicted in this analysis were dif...
In both vertebrates and Drosophila, limb development is organized by a posteriorly located source of the signalling protein Hedgehog (Hh) [1] [2] [3] [4]. In Drosophila, the expression of Hh target genes is controlled by two opposing activities of the transcriptional regulator Cubitus interruptus (Ci), which activates target genes in response to Hh signalling but is converted into a repressor f...
Sonic hedgehog (Shh) regulates a wave of oligodendrocyte production for extensive myelination during postnatal development. During this postnatal period of oligodendrogenesis, we fate-labeled cells exhibiting active Shh signaling to examine their contribution to the regenerative response during remyelination. Bitransgenic mouse lines were generated for induced genetic fate-labeling of cells act...
Gastric cancer is the third leading cause of cancer-related mortality worldwide. Chemotherapy is frequently used for gastric cancer treatment. Most patients with advanced gastric cancer eventually succumb to the disease despite some patients responded initially to chemotherapy. Thus, identifying molecular mechanisms responsible for cancer relapse following chemotherapy will help design new ways...
B-cell chronic lymphocytic leukemia (B-CLL) is characterized by an accumulation of neoplastic B cells due to their resistance to apoptosis and increased survival. Among various factors, the tumor microenvironment is known to play a role in the regulation of cell proliferation and survival of many cancers. However, it remains unclear how the tumor microenvironment contributes to the increased su...
Hedgehog-Gli1 signaling is evolutionarily conserved and plays an essential role in osteoblast proliferation and differentiation as well as bone formation. To evaluate the role of the Hedgehog-Gli1 pathway in the response of osteoblasts to hierarchical biomaterial topographies, human MG63 osteoblasts were seeded onto smooth, microstructured, and micro-/nanotextured topography (MNT) titanium to a...
Dysregulation of the Hedgehog (Hh) signaling pathway is implicated in development many cancers including BCC. PTCH1 and SMO are critical players Hh GLI1 transcriptional activator through which mediated. Mutation or have been shown to constitutively activate pathway. Active canonical Wnt has also be required for pathway–driven We previously identified a novel mechanism by regulates outcome signa...
BACKGROUND Gastric cancer (GC) is characterized by the excessive deposition of extracellular matrix, which is thought to contribute to this tumor's malignant behavior. Epithelial-mesenchymal transition (EMT) is regarded as a crucial contributing factor to cancer progression. Galectin-1 (Gal-1), a β-galactoside-binding protein abundantly expressed in activated cancer-associated fibroblasts (CAFs...
The complex mechanistic array underlying the pathogenesis of myelodysplastic syndrome (MDS) is still unclear. Although dysregulations of different signaling pathways involved in MDS have been described, the identification of specific biomarkers and therapy targets remains an important task in order to establish novel therapeutic approaches. Here, we demonstrated that the Shh signaling pathway i...
