Dr.
Elaine Fuchs is a Professor of Molecular Genetics and Cell Biology
and of Biochemistry and Molecular Biology at the University
of Chicago.
In November
1998 Researchers led by Dr Fuchs at the University of Chicago's
Howard Hughes Medical Center, discovered a new approach to treating
hair loss by using gene therapy. Scientists were able to successfully
transform skin cells into hair follicles in lab mice through
the introduction of a so-called messenger molecule containing
the protein beta catenin. It has been believed told we are born
with a fixed number of hair follicles and can never grow any
more of them, however this study suggested that we now we have
the capability to in fact grow more
While this
research was very exciting, similar experiments on humans are
not likely in the near future. The scientists have created some
very hairy lab mice, but still don't understand how to contain
the hair follicle growth process. According to Dr Elaine Fuchs
you can actually go too far and cause the cells to grow too
much which if left unchecked could lead to the development of
tumors. Scientists still need to understand how this molecule
is regulated inside the cell of the developing hair follicle
to really take it to the level of clinical application.
The overall
goal of Dr. Fuchs' research is to understand the molecular mechanisms
that underlie development and differentiation of the epidermis
and its appendages, and to determine how these processes go
awry in various human diseases of the skin, including genetic
diseases and skin cancer. As a protein chemist and cell biologist,
Dr. Fuchs has focused on characterization of epidermal proteins,
the keratins, and their genes. Through a multifaceted approach
that includes expression of mutant forms of keratins in transgenic
mice, she and her colleagues have uncovered the genetic bases
for a number of human genetic disorders of the skin that arise
as a consequence of defects in these proteins. This reverse
genetic approach has led Dr. Fuchs' group to an understanding
of the proteins that are specific to epidermal function. This
work also has led them to define the genetic bases for disorders
that arise from defects in proteins related to those studied
in the skin, but whose expression resides in muscle and the
nervous system.
