Li-Fraumeni Syndrome

Inquiry

Li-Fraumeni syndrome is an uncommon genetic condition linked with the development of multiple tumors in families, which is also characterized by an inherited germline mutation in the TP53 tumor suppressor gene. Protheragen offers a full scope of services for drug development within Li Fraumeni syndrome including but not limited to preclinical studies, development of custom animal models, therapeutic testing, and trial management support.

Overview of Li-Fraumeni Syndrome

Li-Fraumeni syndrome, or LFS for short, is linked with a predisposition to many cancers, including early-onset cancers cancer, and is estimated to occur in 1: 5,000 to 1: 20,000 people. While the most common association is with sarcomas, brain tumors along with adrenocortical carcinomas, other common cancers which have increased associations are colorectal and gastric adenocarcinomas.

Pathogenesis of Li-Fraumeni Syndrome

Germline pathogenic variants of the tumor suppressor gene TP53 define Li-Fraumeni syndrome. The p53 protein is a crucial regulator of cellular homeostasis. Stressors, including DNA damage, oncogenic stimuli, nutrient shortage, and oxidative stress, trigger the post-translational modification, activation, stabilization, and accumulation of p53 within cells. The tumor-suppressing functions of p53 stem from its regulatory functions over the transcription of several genes that control critical cellular activities, including cell cycle arrest, apoptosis, senescence, DNA repair, and differentiation.

Therapeutic Development Services

Animal Model Development Services

Animal models play a crucial role in understanding the pathophysiological processes of Li-Fraumeni syndrome, as well as in assessing possible treatment options. Our company provides development services for customized animal models which enhances research and intervention evaluation targeting unique genetic and phenotypic manifestations of the syndrome.

Genetically Engineering Model

Using gene editing technology to make animals carry specific p53 gene mutations.

Optional models: p53M/- models, p53+/- models, p53I166T model, etc.

Xenograft Model Development

Implantation of human tumors derived from LFS individuals into immunocompromised animals (e.g., NOD/SCID mice), preserving the heterogeneity of the original tumor.

The intricacies of Li-Fraumeni syndrome are incredibly difficult and my team is focused on solving them to devise effective drug development strategies, pharmacokinetic services, and safety testing.
