Biomarkers Of Orthodontic Tooth Movement, Max Kazantcev, Kamal Thapaliya, Marie Tolarova, Miroslav Tolar May 2022

Biomarkers Of Orthodontic Tooth Movement, Max Kazantcev, Kamal Thapaliya, Marie Tolarova, Miroslav Tolar

Excellence Day

Orthodontic tooth movement leads to remodeling of periodontal ligament, alveolar bone, and gingiva. Tooth movement is characterized by bone deposition at sites of tension and bone resorption at pressure sites. Due to a sterile inflammatory process in the PDL space, a flow rate of gingival crevicular fluid (GCF) is increased and its composition is modified. Various cell-signaling pathways are activated, which ultimately stimulate PDL turnover. Biochemical and cellular processes associated with orthodontic tooth movement may be better understood if we study changes of specific biomarkers in GCF during orthodontic therapy. Such information can be used clinically to choose a proper …

The Role Of Inflammation In Epithelial-Mesenchymal Transition In Oral Squamous Cell Carcinoma: Literature Review, Preliminary Data, And Proposal Of Experiments, Rachel Choi, Jisoo Kim, Adria Frazier, Takahiro Chino

Excellence Day

The epithelial-mesenchymal transition (EMT) is a trans-differentiation process of epithelial cells into motile mesenchymal cells. It plays an integral role in embryonic development, wound healing and cancer progression. During EMT, epithelial cells lose their cellular polarity due to the loss of intercellular adhesion and acquire migratory and invasive characteristics associated with mesenchymal cells. EMT is tightly regulated by a number of distinct molecular processes which allow its initiation and progression to completion. These processes include activation of transcription factors, expression of specific cell-surface proteins, reorganization and expression of cytoskeletal proteins, production of extracellular matrix-degrading enzymes and changes in the expression …
