Title: Innovations of Yuanlei Hu in Genetic Engineering

Introduction

Yuanlei Hu is a prominent inventor based in Beijing, China. He has made significant contributions to the field of genetic engineering, particularly in enhancing the tolerance of fish to low dissolved oxygen stress. His innovative work has the potential to revolutionize aquaculture practices.

Latest Patents

Yuanlei Hu holds a patent for a recombinant gene that enhances the ability of fish to tolerate low dissolved oxygen stress. The invention discloses a recombinant gene utilizing the carp β-actin gene promoter as a promoter and the hemoglobin gene as a target gene. This recombinant hemoglobin gene is driven by the carp β-actin promoter. The research primarily focuses on zebrafish as the modeling organism, where the recombinant gene is microinjected into zygotes. Following PCR screening and a 156-hour low dissolved oxygen stress test, transgenic fish were obtained with a survival rate of 92%, significantly higher than the 65% survival rate of the control fish group. The vhb transgenic zebrafish exhibit enhanced hypoxia tolerance. When applied to economically farmed species such as blunt snout bream and common carp, this recombinant gene also improves their hypoxia tolerance. This genetically improved breeding technique may be widely utilized for developing new excellent farmed species with enhanced hypoxia tolerance.
