According to Pearce, “the question of [human germline engineering] comes down to an analysis of risk-reward ratios – and our basic ethical values, themselves shaped by our evolutionary past.” [69] Bioethicist Julian Savulescu in turn proposes the principle of procreative beneficence, according to which “couples (or single reproducers ...
Spermine oxidase is an enzyme that in humans is encoded by the SMOX gene. [5] [6] [7] Function. The product of this gene is the polyamine oxidase. This enzyme ...
Spermine is synthesized from the reaction of spermidine with SAM in the presence of the enzyme spermine synthase. The polyamines undergo rapid interconversion in the polyamine cycle, in which putrescine leads to synthesis of spermidine and spermine, with degradation of these polyamines to form putrescine, which can begin the cycle again.

A draft of the 11th Amendment to the Criminal Law of the People's Republic of China in 2020 has incorporated three types of crime: the illegal practice of human gene editing, human embryo cloning and severe endangering of the security of human genetic resources; with penalties of imprisonment of up to 7 years and a fine.
Ethical issues related to gene therapy and human genetic enhancement concern the medical risks and benefits of the therapy, the duty to use the procedures to prevent suffering, reproductive freedom in genetic choices, and the morality of practicing positive genetics, which includes attempts to improve normal functions.
Scientists think genetically-modified animals could one day be the solution to an organ supply shortage that causes thousands of people in the U.S. to die every year waiting for a transplant.
The SAT1 gene is 3,069 base pairs long. There are 171 amino acids and its molecular mass is 20024 Da (daltons). In 1992 at The Johns Hopkins University School of Medicine, Lei Xiao and several others cloned over 4000 base pairs of the region containing the coding sequence of the SAT1 gene also referred to as SSAT-1, SSAT, SAT, KFSD, DC21, KFSDX gene.

Spermine is a polyamine involved in cellular metabolism that is found in all eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine . It is an essential growth factor in some bacteria as well.
