Unveiling Cellular Secrets through Flash Forward Genetics

In the realm of biomedical research, the laboratory led by Janice L. Brissette, Ph.D., Associate Professor of Cell Biology at SUNY Downstate Health Sciences University, stands at the forefront of exploring mammalian development and disease.

Dr. Brissette’s research not only advances our scientific knowledge but also holds promise for the development of novel treatments and therapies, significantly impacting patient care and health outcomes.

The focus of Dr. Brissette and her innovative team is on dissecting the complex regulatory mechanisms in the skin, brain, and intestines. Their primary goal is to unravel how morphogenetic regulators, such as transcription factors and intercellular signals, influence critical aspects of cellular and tissue development. These aspects include directing cellular development and function, promoting tissue renewal and regeneration, determining the polarity and size of developing tissues, and targeting cells, whether normal or malignant, to specific anatomical locations.

A central question in biomedical research is how to identify significant molecular interactions. Understanding these interactions is crucial for comprehending any biological trait, as every biological phenomenon is a web of intricate interactions. Biologists, therefore, dedicate a significant portion of their work to uncovering these interactions. Like assembling a jigsaw puzzle, they piece together these interactions to reveal molecular mechanisms, offering the most definitive explanations for biological phenomena.

However, the study of inherently intractable traits presents a significant challenge. Intractable traits are characteristics or conditions that are particularly challenging to study due to their complexity, variability, or the limitations of current research methods. These traits—particularly those unique to humans or mammals—often prove difficult to analyze through conventional genetic screening methods and remain elusive to researchers.

The novel approach developed by Dr. Brissette and her team, which she has named "flash-forward genetics," represents a pivotal advancement in tackling these formidable challenges.

Employing this method, Brissette's laboratory has made significant discoveries. They identified the first nude-like locus, a gene that mimics the mammalian nude locus, crucial for the development of hair and thymus. This discovery, along with their unveiling of a unique class of skin cells known as pigment recipients, has profound implications for our understanding of skin biology and its disorders. These cells control the behavior and size of the melanocyte population, thus orchestrating their own pigmentation, and offer insights into potential therapeutic applications for skin-related conditions.

The laboratory's current projects are equally ambitious and diverse, encompassing the analysis of murine models of vitiligo, the congenital brain malformation called Dandy-Walker Syndrome, small bowel adenocarcinoma, and melanoma.  The laboratory is currently funded by a grant from the National Cancer Institute.
