Title: Louis-Marie Houdebine: Innovator in Transgenic Animal Research

Introduction

Louis-Marie Houdebine is a prominent inventor known for his contributions to the field of transgenic animal research. He is based in Buc, France, and holds a total of four patents. His work primarily focuses on the expression of transgenes in milk from transgenic animals, which has significant implications for biotechnology and medicine.

Latest Patents

One of Houdebine's latest patents is titled "Position-independent and tissue specific expression of a transgene in milk of transgenic animals." This invention relates to an isolated insulator DNA molecule that consists of the 5' and 3' regions of the porcine wrap gene locus. It provides a method for insulating the expression of an introduced heterologous gene from silencing and variegation effects in chromatin. The invention also encompasses mammalian cells that include this insulator DNA molecule and non-human animals capable of expressing a polypeptide of interest in milk.

Another significant patent is for a "Transgenic rabbit that expresses a functional human lipoprotein (a)." This patent describes a transgenic rabbit that contains genomic DNA sequences encoding apolipoprotein (a) and apolipoprotein B polypeptides. These components are capable of combining to produce lipoprotein (a). The patent also outlines a process for creating such a rabbit and its use in identifying compounds effective in treating human diseases associated with Lp(a) expression.
