Gene Editing Controversy Continues

Gene Editing Controversy Continues
We recently reported on the gene editing controversy when a scientist used CRISPR/Cas9 gene editing to produce “superior” human babies. Jiankui He, a Chinese geneticist, announced that twin girls had been born with genes edited by his medical team to reduce the risk of contracting HIV.

For several years experts have predicted that it will be possible in the future to produce “designer babies” by the technique He has used. The twins’ father has HIV, but their mother does not. We pointed out previously that human knowledge is not good enough to know what collateral damage we may create in such a project. There are also issues about whether humans should ever genetically modify human life. Playing God has enormous responsibilities, and the gene editing controversy brings up concern about the old “Frankenstein Complex.”

Since He’s announcement there have been numerous articles and responses by experts in the field backing what we said in our article:

Researchers say there was virtually no chance the girls would have been infected with HIV since their mother doesn’t carry the virus.

No evidence can verify that the editing was successful and didn’t damage other genes.

Previous CRISPR/Cas9 research has shown that some cells in embryos may be incompletely edited or escape editing entirely creating what is called a “mosaic embryo.”

He was asked why the research was done in secret and why he chose to violate established rules of CRISPR/Cas9. He refused to answer those questions.

Julian Savulescu who is a bioethicist at the University of Oxford said, “I liken it to Russian roulette. You can pull the trigger and not kill, but it doesn’t mean that what you did was right.” We would suggest that this gene editing controversy is a classic of example of the fact that science cannot determine the way its discoveries will be used. In this case, it appears this was a desire to become famous, rather than trying to improve the well being of human life.

There are many Christians who are scientists working with CRISPR/Cas9 and who have stated their dismay and feeling that their greatest fears are being realized. The gene editing controversy continues, and we will hear more of this.

Rest of the Story on Gene Editing

Rest of the Story on Gene Editing
Many years ago there was a well-known radio news personality named Paul Harvey. He made a career out of digging into details on stories that were not publicized by the media. He called the reporting “The Rest of the Story.” People close to Harvey said that he got some heat from media people who felt he had made them look bad by revealing details they missed. With the general public, however, he was very popular. We want to examine the rest of the story on gene editing.

There has been a great deal of media reporting about CRISPR-Cas9 which is a tool for editing DNA introduced in 2012. Researchers hope that science can treat a wide range of genetic diseases by altering human DNA. The problem is that our understanding in this area is very primitive. Bioethicists writing in the Wall Street Journal (December 15, 2018, page C3) report, “scientists have only begun to understand what the tens of thousands of individual genes do. Moreover, they are far from unraveling how those genes interact with each other.”

When researchers deleted a gene that limits muscle growth in rabbits, the rabbits had enlarged tongues. Doing the same thing with pigs produced additional vertebrae. In calves the change caused the calves to die prematurely. Lambs grew too large in the womb to be born naturally. Lisa Moses who is a bioethicist at Harvard says, “Humans have a long history of messing around in nature with all kinds of unintended consequences. It’s really hubris of us to assume that we know what we are doing and that we can predict what kinds of bad things can happen.”

There are lessons to learn here. CRISPR has the potential to correct damage to DNA caused by human carelessness, pollution, and mismanagement. The rest of the story on gene editing is still to be written. When a Chinese scientist claims to have produced the first gene-edited human babies, there has to be immediate condemnation by the scientific community. Over the years, outstanding scientists have pointed out that science lacks the capacity to determine the use of its discoveries.

We desperately need Christians who are capable scientists using their faith in God to determine those uses. Will CRISPR be used to eliminate genetic diseases, or will it be used by political demagogues to produce pathogens that kill millions of innocent people? The Nobel Peace Prize was started by a man who discovered dynamite and was appalled at the way it was being used to fight wars. That kind of sensitivity is needed in today’s genetic research to write the rest of the story on gene editing.

Another lesson in all of this is that the complexity of the genetic code of life cannot be the result of chance – a blind watchmaker as some have suggested. Wisdom calls out in Proverbs 8, “O you simple ones, understand wisdom … for wisdom is better than rubies; and all things that may be desired are not to be compared to it. I wisdom dwell with prudence and find out knowledge of witty inventions … The Lord possessed me in the beginning of His way, before His works of old … Hear instruction and be wise and refuse it not.”

CRISPR and God’s Design

CRISPR and God's Design
The general media and scientific journals have given great attention to something called CRISPR (pronounced like the name of the refrigerator drawer where you stash fresh veggies). CRISPR was first reported in scientific journals and papers in 2012. Now it is being used by scientists all over the world as a method to modify human embryonic stem cells and answer questions about basic biology and development. Here is a sample of what Wikipedia says about it:

“CRISPR is an abbreviation of Clustered Regularly Interspaced Short Palindromic Repeats… A simple version of the CRISPR/Cas system, CRISPR/Cas9, has been modified to edit genomes… CRISPR/Cas genome-editing techniques have many potential applications, including medicine and crop seed enhancement. The use of CRISPR/Cas9-gRNA complex for genome editing was the AAAS’s choice for the breakthrough of the year in 2015. Bioethical concerns have been raised about the prospect of using CRISPR for germline editing.”

That last statement about this technique concerns many people. Are we “playing God” feeling that we can improve on what God has created? Is human genetic engineering going to threaten a catastrophic mistake in the future? Hollywood is already on this with dramas like Netflix’s Luke Cage.

CRISPR exploits something that microbes commonly do in the natural world. Bacteria defend themselves against viruses and other DNA in the environment by having snippets of foreign genetic material as molecular spacers which serve as borders. What scientists are doing is to pick those characteristics that CRISPR can use to eliminate a bad gene and insert a good one in place of it. We are taking something that God has designed into nature and using it to eliminate genetic disorders that may have been caused by human abuse of the environment.

This could be the tool to eliminate nerve damage and give quadriplegics and paraplegics full use of their arms and legs. Trials are already going on to eliminate cystic fibrosis, hemophilia, muscular dystrophy, many forms of cancer, sickle cell anemia, beta thalassemia, and leukemia. This is not replacing God’s original design but rather using some of the tools God created to repair things damaged by time and human abuse. Scientists are harnessing an ancient biological process to edit the code of life. God’s design is what makes this possible and offers great hope for the future of people afflicted with disorders which have not been within our medical reach in the past.

Prison Suicide Rates Skyrocket

Prison Suicide Rates Skyrocket
Yesterday we discussed an article by atheist Michael Shermer in which he stated that as atheism replaces belief in God “we should continue working on grounding our morals and values on viable secular sources such as reason and science.” (Scientific American, April 2018, page 77). At the same time Shermer’s article came out, we received a report on prison suicide rates.

NewLife Behavior Ministries issued a report of an increase in suicides in Texas prisons. The data came from the University of Texas Medical Branch saying that attempted suicides in Texas prisons jumped from 65 to 150 in the past four years. Statistics on suicides are very complicated, but every study we have seen has shown a huge increase in attempted suicides. The increase applies to all segments of the population, not just prison suicide rates but the general public as well.

The secular sources for morals and values that Shermer recommends would include people like atheists Peter Singer and Richard Dawkins. They advocate euthanasia for the “unfit” in society including Down Syndrome, mentally ill, and mentally deficient people. Singer is the Ira W. DeCamp Professor of Bioethics at Princeton University. He advocates for infanticide to eliminate defective children and for animal rights. In his book Practical Ethics, he concedes that the question of why we should act morally “cannot be given an answer that will provide everyone with overwhelming reasons for acting morally.”

The biblical perspective is that all humans have value because they are created in the image of God. That is radically different from the secular view that we are just animals with no more value than any other animal. Suicide is directly connected to what we understand a human to be. The Christian view is that there is no such thing as “worthless human trash” or “unfit people.”

Gene Editing and Better Babies

Gene Editing
A major debate is in the works as scientists experiment with gene editing using CRISPR/Cas9 to fix mutations that cause heart and blood disorders. CRISPR/Cas9 acts as molecular scissors to alter human DNA. The technology is advancing so rapidly that scientists and ethicists are holding conferences to discuss how the technology should be used.

The Hastings Center, which is a bioethics research institute, is sponsoring discussions among experts attempting to give some guidelines for the proper use of gene editing. A panel of ethicists convened by the National Academies of Sciences and Engineering and Medicine has said that gene editing should be used to correct diseases, but not to create characteristics that don’t have to do with health.

Movies like Gattaca have given an awareness of the potential problems with genetic engineering. The Center for Genetics and Society has pointed out that people who are taller and fair-skinned tend to make more money than the general population. The question of whether parents should edit the genes of their children to give those characteristics is an extreme example of how gene editing might be misused.

In the past, we have pointed out the difficulty with any new scientific discovery. We raised the question of whether cloning would be used to produce better crops and save endangered species, or whether it would produce a strain of super-humans endowed with the characteristics of a demented ruler like Hitler–the Boys from Brazil scenario.

From a biblical standpoint, we have to realize that when God created the first humans, they were physically perfect. Many of our diseases and disorders have to a great extent been the product of human greed and foolishness. Pollution, misuse of chemicals and radiation, and a host of recreational drugs have produced a large number of maladies in humans. To be able to go into the cells and edit the DNA to correct genetic disorders may be appropriate, but the potential for misuse is always there.

The moral conviction of the people making these decisions becomes the critical factor. Rather than decry advances in science, we need to join the search to find answers to disease and suffering. Gene editing is the future, let us encourage the best minds in the Christian community to use their God-given talents and abilities to find solutions and direct the use of our knowledge and technology.

Bioethics and Playing God

DNA Molecules

Over the past several months, the media has published dozens of articles about a new genetic technique of modifying DNA called CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats). This method can be used to edit the embryonic or reproductive cells of human beings, passing on genetic changes to future generations. It makes altering our DNA faster and easier. The media has emphasized the possible positive impact of this technique. The Week magazine (March 14, 2016) called it “genetic research nearing a breakthrough that could transform the world.” We know that many diseases are genetic in nature, including sickle-cell anemia, Huntington’s disease, muscular dystrophy, and some forms of cancer. The problem is that with some 20,000 genes involved and the fact that genes interact, the possible negative consequences of making permanent changes to human DNA are very high. This technique could potentially be used to alter the genomes of a child to suit parental preferences. The question is whether CRISPR will be used for therapy or enhancement or both. This bioethical question cannot be answered by science alone.

For almost 50 years, this ministry has tried to demonstrate how science enhances faith. At the same time, faith can answer questions that science cannot answer. The question of shaping the human body to suit our desires is an issue of science and faith because we are more than just a body. We were created in God’s image, but we are not God. Whether humans use CRISPR in a constructive way or in a potentially destructive way will be answered by the moral and religious belief systems of those who decide how this new technique will be used. An interesting article on this subject is in the March 2017, issue of Christianity Today, pages 49-51.

Stem Cell Scams and Moral Issues

Stem Cells
Stem Cells

For several years now we have talked about the morality of fetal stem cells and what they can be used for and where they come from. The original fetal stem cells came in many cases from aborted babies. The concern of many people was that if the medical establishment paid for fetal stem cells that women might find it financially lucrative to get pregnant, have an abortion, and sell the fetal stem cells. As research continued, it was discovered that a large percentage of stem cell treatments could be done successfully with adult stem cells. All of this was carefully controlled by the Food and Drug Administration and was based on good science.

A study released on June 30, 2016, by University of California stem cell scientists reports that 570 clinics are now offering stem cell treatments for things that in many cases have poor scientific support. An extreme example is the offering of cosmetics that will make your face look like a baby’s “because the stem cells came from the umbilical cord of a baby.” Not only are some of these claims probably not true, but they can be dangerous. Stem cells are cells that can grow into almost any kind of cell, and that makes them useful for medical purposes. The problem is that they can also grow into tumors and the tumors can migrate to other parts of the body.

God’s design of the human body is incredible, and over the years we have had numerous articles about that in the “Dandy Designs” section of our printed periodical. However, changing the use of what God has designed and created may sometimes be beyond human reach. At the very least, we need to move slowly and carefully as we try to change the use of or improve the function of God’s design. Data from Austin American-Statesman, July 3, 2016, page A8.
