英文摘要
DESCRIPTION: (Adapted from the applicant's abstract) Upon cutaneous trauma,
a complex cascade of events is initiated within the wounded epidermis,
"activating" resident keratinocytes (NHKs) and resulting in altered cellular
growth and motility. Although the definitive signals that trigger
commitment of basal keratinocytes to a pathway of migration and regenerative
maturation remain largely unknown, the loss of adherence to the basement
membrane is a critical aspect of epidermal migration and differentiation and
likely involves regulated expression of "anti-adhesive" matrix proteins.
One anti-adhesive protein that the investigators have identified as a
potential regulator of the processes of re-epithelialization and
regenerative maturation in NHKs is SPARC (also known as osteonectin and
BM-40) SPARC is a widely distributed and highly conserved extracellular
matrix (ECM)-associated glycoprotein that has been implicated in processes
requiring tissue remodeling. Recent evidence in SPARC knockout mice
suggests that loss of SPARC expression is associated with a defect in dermal
wound repair. Inhibition of SPARC expression in stable anti-sense
tranfectants severely inhibits the ability of basal NHKs to migrate in
response to wounding thus supporting their hypothesis that expression of
SPARC is a critical event in epidermal wound repair. Following wound
closure, NHKs begin to differentiate and vertically migrate toward the
surface of the skin. Anti-adhesive events are also associated with this
process; the investigators have shown previously that SPARC is specifically
induced prior to loss of adherence to the basement membrane and subsequent
terminal differentiation of NHKs. Specific Aims for this project are: I.
Determine the mechanisms underlying SPARC expression and the cell-type
specificity of expression in subpopulations of NHKs undergoing: (A) Lateral
migration in response to wounding and; (B) Vertical migration in response to
regenerative maturation induced by NaBr. II. Ascertain the mechanism by
which molecular perturbation of SPARC expression in NHKs alters: (A) NHK
cell cycle kinetics: (B) NHK response to wounding; and (C) NHK
differentiation. III. Determine how molecular perturbation of SPARC
expression affects the regulation of wound-related changes in keratinocyte
gene expression.
