Grants We Funded

Grant applicants for the 2023 cycle requested a total of nearly $4 million dollars. The PSF Study Section Subcommittees of Basic & Translational Research and Clinical Research evaluated nearly 140 grant applications on the following topics:

The PSF awarded research grants totaling over $1 million dollars to support nearly 30 plastic surgery research proposals.

ASPS/PSF leadership is committed to continuing to provide high levels of investigator-initiated research support to ensure that plastic surgeons have the needed research resources to be pioneers and innovators in advancing the practice of medicine.

Focus Area

Hemangiomas are the most common head and neck tumors in the pediatric age group. Despite their frequency, little is known about the factors controlling their growth and regulation. We have identified two transcription factors CTCF (CCTCCC binding factor) and BORIS (Brother of the regulator of imprinted sites) that play a major role in the regulation of hemangioma growth, acting through IGF2, a critical growth factor in pediatric tumors. MicroRNAs are recently discovered molecules that are known to regulate a host of physiological functions including growth and development of tumors. We have additionally identified two microRNAs, MicroRNA23a (mir23a) and MicroRNA23b (mir23b) that are very strongly correlated to the expression of the transcription factors CTCF and BORIS, thus influencing the growth of hemangiomas. We therefore propose: 1. To formally demonstrate the regulation of CTCF and BORIS by mir 23a and 23b in an in vitro model 2. To create a transgenic mouse model of hemangiomas by over expressing microRNA 23b, using an endothelial cell specific promoter Tie-2 3. To propose a new method of molecular classification of hemangiomas based on microRNA profiles through a microarray analysis
