Researchers are expected to find a clue as to how the body structure of the human body, including the heart and other organs, is formed.

A research team led by Professor Reiko Kuroda of the Institute of Integrated Engineering at the Chubu University University found a gene that determines the way in which the shell of a screw shell is twisted, the Asahi newspaper reported.

The twisted direction of the screw shell is right, but it turns out that the gene that the research team found is twisted to the left, which prevents it from functioning.

The researchers studied the gene of European snail (snake shellfish), a type of screw shell that is almost twisted to the right, and studied the difference between the right and left twist. As a result, Lsdial 1 ‘were different.

The gene conversion technology, the genome editing, made it impossible for this gene to function, and the cochlea ‘s shell twisted to the left. The left kink is confirmed to continue to the fifth generation. In addition, when the embryo is divided into two, it is revealed that the gene has a difference in the direction of division of the right and left twist.

Professor Kuroda pointed out that “the left and right twists of the shell are determined by the structure of the body,” he pointed out. “Because the human structure is complex, but the root is the same, it helps to research the fields of regenerative medicine such as how the body structure is formed. “He said.
