The role of epithelial-mesenchymal transition (EMT) in metastasis remains controversial. EMT has been postulated as an absolute requirement for tumor invasion and metastasis. Three different models including incomplete EMT, mesenchymal-epithelial transition (MET), and collective migration have been proposed for the role of EMT in cancer invasion and metastasis. However, skepticism remains about...

Background: Hyperuricemia contributes to kidney injury, characterized by tubular injury with epithelial–mesenchymal transition (EMT). Wnt5a/Ror2 signaling drives EMT in many kidney pathologies. This study sought to evaluate the involvement of Wnt5a/Ror2 in hyperuricemia-induced EMT in kidney tubular injury.Methods: A hyperuricemia model was performed in male Swiss background mice (3 months old,...

Background and purposeTo investigate the accuracy of dwell position detection with a combined electromagnetic tracking (EMT) brachytherapy (BT) system for treatment verification, by quantifying positional errors due to EM field interference in typical pelvic BT clinical settings.Materials methodsDedicated prostate cervix phantoms were imaged CT. For phantom, Utrecht applicator + interstitial ca...

Epithelial-mesenchymal transition (EMT) has been considered essential for metastasis, a multistep process including local invasion, intravasation, extravasation, and proliferation at distant sites. However, controversy remains as to whether EMT truly happens and how important it is to metastasis. We studied the involvement of EMT in individual steps of metastasis and found that p12(CDK2-AP1), a...

Endometriosis is a common, estrogen-dependent disease, in which endometrial tissue grows the peritoneal cavity. These lesions often express low levels of progesterone receptors (PR), potentially play an important role insufficient response to progestin treatment. Here, we uncover interconnection between downregulated PR expression and epithelial-to-mesenchymal transition (EMT) endometriotic les...

Objectives Core competencies are considered the foundation for establishing Emergency Medical Technician (EMT) and paramedic curricula, and for ensuring performance standards in the delivery of prehospital care. This study surveyed EMT instructors and medical directors to identify the most desirable core competencies for all levels of EMTs in Taiwan. Methods A principal components analysis wi...
