Protein arginine methyltransferase 1 interacts with Gli1 and regulates its transcriptional activity

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 9 δευτερόλεπτα
Abstract Protein arginine methylation, which is mediated by the protein arginine methyltransferases (PRMTs), is associated with numerous fundamental cellular processes. Our previous studies have shown that PRMT1 activated Hedgehog signaling in the esophageal squamous cell carcinoma (ESCC) cells and promoted the growth and migration of cancer cells. However, the detailed mechanisms are unknown. In this study, it was found that PRMT1 interacted with the transcriptional factor Gli1 (glioma-associated oncogene homolog 1) in ESCC cells. The DNA-binding domain (DBD) of Gli1 is responsib...περισσότερα »

Inhibition of carbonic anhydrase potentiates bevacizumab treatment in cholangiocarcinoma

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 9 δευτερόλεπτα
Abstract Cholangiocarcinoma (CCA) is a unique liver cancer subtype with an increasing incidence globally. The lack of specific symptoms and definite diagnostic markers results in a delayed diagnosis and disease progression. Systemic chemotherapy is commonly selected for advanced CCA even though its advantages remain unknown. Targeted therapy, especially anti-vascular endothelial growth factor (VEGF) therapy, is promising for CCA; however, improvements in the therapeutic regimen are necessary to overcome subsequent resistance. We demonstrated VEGF expression was higher in CCA cell ... περισσότερα »

Estradiol Rapidly Attenuates ORL-1 Receptor-Mediated Inhibition of Proopiomelanocortin Neurons via Gq-Coupled, Membrane-Initiated Signaling

Estradiol rapidly regulates the activity of arcuate nucleus (ARH) proopiomelanocortin (POMC) neurons that project to the medial preoptic nucleus (MPN) to regulate lordosis. Orphanin FQ/nociceptin (OFQ/N) acts via opioid receptor-like (ORL)-1 receptors to inhibit these POMC neurons. Therefore, we tested the hypothesis that estradiol excites POMC neurons by rapidly attenuating inhibitory ORL-1 signaling in these […]
