Quantitative Analysis Of Peri-Implant Collagen Fiber Orientation Around External Hexagon And Morse Taper Implant Connections: A Dog Model Study

Faculty, Staff and Student Publications

Background: Peri-implant soft tissue stability depends on the implant-abutment interface and collagen fiber organization. Unlike natural teeth, peri-implant fibers exhibit a less favorable orientation, potentially weakening the biological seal. Implant connection design may influence this collagen arrangement and tissue integrity.

Materials and methods: Eighteen immediately loaded implants (n = 9 per group) were placed in nine mongrel dogs. Group I received external hexagon implants, while Group II received Morse taper implants. After a 4-month healing period, animals were euthanized and specimens were processed for histological evaluation. Collagen fiber orientation was analyzed using polarized light microscopy and quantified with ImageJ software. …

Kras G12c And Kras G12d Respond To Lipid Metabolism In An Allele-Specific Manner

Faculty, Staff and Student Publications

KRAS mutated at hotspots G12, G13, and Q61 possess profound allele-specific oncogenesis. Signaling of KRAS mutants is mostly compartmentalized to the proteolipid nanoclusters on the plasma membrane (PM), illustrating critical roles of spatiotemporal organization in KRAS cancer signaling. The activated GTP-bound KRAS molecules, including the wild type and mutants, have been traditionally thought to favor similar lipids. We recently reported distinct lipid sensing capabilities of different KRAS mutants, especially with KRASG12D favoring unsaturated lipids and KRASG12C gaining additional enrichment of saturated lipids. As such, KRAS mutants may respond to lipid acyl chain remodeling in an allele-specific manner. Lysophosphatidylcholine acyltransferase 1 …

Erk-Mediated Phosphorylation Of Yap Defines A Noncanonical Fgf Signaling Mechanism In Stem Cells, James F Martin, Jun Wang

Faculty, Staff and Student Publications

While Fgf and Hippo-Yap signaling are fundamental for proper development, homeostasis, and disease, their crosstalk remains largely unknown. Here, we identified that Yap and Taz, canonical Hippo effectors, function as noncanonical effectors of Fgf signaling to maintain the proper function of neural crest (NC) lineages. NC cells are a multipotent stem cell population during vertebrate embryogenesis that contribute to numerous structures and diverse cell lineages, including craniofacial and cardiac tissues, neurons, and suture mesenchymal cells (SMCs), a specified cell population required for cranial bone growth and repair. We observed that activation of Fgf signaling in NC cells and NC-derived SMCs …
