A five-year federal grant totaling more than $1.7 million has been awarded for skin cancer research led by Dr. Rebecca Morris, leader of the stem cells and cancer section at the Hormel Institute.
Morris, whose research uses adult, non-human stem cells, has been working to identify stem cell-regulating genes for 10 years. She now has found a gene that appears to be linked to stem cell numbers and helping to protect against skin tumor development.
The gene also might have an immune function in the skin that can fight bacteria and protect against environmental damage. As stem cell research leads to discoveries to improve health, these cells can be obtained through various ways such as from adult tissue stem cells or through bio-engineering to avoid the ethical issues of how to secure stem cells for treatment.
The new project, funded through 2017, will further Morris' research on that gene and the idea that, through using the gene, stem cells could be used to function as a way to protect the body.
The down side of stem cells is that they seem to be targets for cancer development, Morris said.
This is exciting for us because a gene whose function is to protect may do double duty by regulating stem cell activity related to the immune system, she said. If we can identify this gene, then maybe we could find a way to turn off the stem cells if theyre growing too fast, such as in cancer and other diseases involving too rapid cell growth.
With the title Identification of a Keratinocyte Stem Cell Regulatory Gene in the KSC2 Locus, the project is funded through the National Institute of Arthritis and Musculoskeletal and Skin Diseases, part of the National Institutes of Health.
The key is to find the genes that control the number and growth potential of epidermal stem cells, Morris said. Then scientists could create more stem cells or make them grow faster, for example, to heal an ulcer or the thinning of skin from aging.
Morris, who joined the institute in 2008, focuses her research on stem cells responsible for healing wounds, maintaining normal tissue integrity and cancer. Her lab uses adult stems cells isolated from the skin through a technique Morris developed when she was a post-doctorate at MD Anderson Cancer Center in Houston.
