Definitions

  • a cell may become cancerous by virtue of the transformation of a portion of its DNA into an oncogene (i.e.. a gene which, on activation, leads to the formation of malignant tumor cells).
  • oncogenes encode proteins that are aberrant tyrosine kinases capable of causing cell transformation.
  • the overexpression of a normal proto-oncogenic tyrosine kinase may also result in proliferative disorders, sometimes resulting in a malignant phenotype.
  • Receptor tyrosine kinases are enzymes which span the cell membrane and possess an extracellular binding domain for growth factors such as epidermal growth factor, a transmembrane domain, and an intracellular portion which functions as a kinase to phosphorylate specific tyrosine residues in proteins and hence to influence cell proliferation.
  • Other receptor tyrosine kinases include c-erbB-2, c-met, tie-2, PDGFr, FGFr, and VEGFR. It is known that such kinases are frequently aberrantly expressed in common human cancers such as breast cancer, gastrointestinal cancer such as colon, rectal or stomach cancer, leukemia, and ovarian, bronchial or pancreatic cancer.
  • EGFR epidermal growth factor receptor
  • tyrosine kinase activity is mutated and/or overexpressed in many human cancers such as brain, lung, squamous cell, bladder, gastric, breast, head and neck, oesophageal, gynecological and thyroid tumors. Accordingly, it has been recognized that inhibitors of receptor tyrosine kinases are useful as selective inhibitors of the growth of mammalian cancer cells.
  • erbstatin a tyrosine kinase inhibitor
  • EGFR epidermal growth factor receptor tyrosine kinase
  • selective inhibitors of certain receptor tyrosine kinases are useful in the treatment of abnormal cell growth, in particular cancer, in mammals.
  • FAK farnesoid adhesion kinase
  • lck lassion kinase
  • src src
  • abl serine/threonine kinases
  • PTK Protein-Tyrosine Kinase 2
  • FAK a cytoplasmic, non-receptor tyrosine kinase
  • FAK was subsequently found to be a tyrosine kinase that localizes to focal adhesions, which are contact points between cultured cells and their underlying substratum and sites of intense tyrosine phosphorylation.
  • FAK is phosphorylated and, thus, activated in response to extracellular matrix (ECM)-binding to integrins.
  • ECM extracellular matrix
  • FAK is found at elevated levels in most human cancers, particularly in highly invasive metastases.
  • Various compounds, such as styrene derivatives, have also been shown to possess tyrosine kinase inhibitory properties.

The incision is carried through to the bone, and a 1 mm hole is drilled 4 mm proximal to the distal aspect of the tibial tuberosity 2 mm medial to the anterior ridge.

To minimize soft tissue damage, care is taken not to displace the fracture. The skin is closed with monofilament nylon sutures. The operation is performed under sterile conditions. Radiographs of all fractures are taken immediately after nailing, and rats with fractures outside the specified diaphyseal area or with displaced nails are excluded.

  • Masson-Trichrome stained mid-frontal sections are used for visualization of the cellullar and tissue response to fracture healing with and without treatment. Sirius red stained sections are used to demonstrate the characteristics of the callus structure and to differentiate between woven bone and lamellar bone at the fracture site. The following measurements are performed: (1) fracture gap - measured as the shortest distance between the cortical bone ends in the fracture, (2) callus length and callus diameter, (3) total bone volume area of callus, (4) bony tissue per tissue area inside the callus area, (5) fibrous tissue in the callus, and (6) cartilage area in the callus.
  • Biomechanical Analysis The methods for biomechanical analysis have been previously published by Bak and Andreassen (The Effects of Aging on Fracture Healing in Rats. Calcif Tissue Int 45:292-297, 1989). Briefly, radiographs of all fractures are taken prior to the biomechanical test.
