Mutation - Part One

DENIABLE STATISTICS
Although I have no source of reference to validate this statement, I'd say that 80% of mutations in the movies are caused by viruses. Let us examine one of these movies in great detail, as it provides interesting insight into the follies of science.


I AM LEGEND PREDICTS THE FUTURE
The brilliant thing about I Am Legend is that the movie tells the story of a genetic mutation that will ravage the human and dog population, any day now. The fall of man is a measles virus genetically re-engineered by scientists looking for a cure for cancer.


People have known for more than 100 years that certain viruses have the potential to treat cancer and shrink tumors(1). As a matter of fact, the early part of the 20th century saw attempts to treat cancer with measles, rabies and smallpox. Using herpes virus to battle cancer is also of interest to researchers.

Herpes. Cure your cancer, make sex awkward(2).

KILLER VIRUSES
A virus is essentially a packet of genetic information for making more viruses. First the virus infects a target cell. Through a series of steps instigated by viral enzymes, the virus will insert its own strand of DNA (genetic information) into the DNA of the host cell. Viral DNA is now a part of the cell's genetic make-up and the host cell will get busy making new viruses. Any time the cell reproduces, it also reproduces the viral DNA in its nucleus as if it were its own.

For you trivia buffs, here's a representation of viral reproduction.

To over-simplify the process, using the tiny graphic, above:
1. The virus binds to the cell wall
2. The virus fuses with and enters the cell
3, 4, 5. The virus inserts its genetic material into the DNA in the nucleus of the host cell.
6, 7. The cell starts making viral components.
8. The cell assembles the virus
9. The new viruses start budding out of the cell membrane, going off to infect other cells.

Easy peasy!

WHAT DOES THIS HAVE TO DO WITH CANCER?
The general idea is that you engineer an oncolytic adenovirus to target only cancer cells. The virus infects the cell, uses the tumor cell to make more virus, and kills the infected cell as the new viruses burst out of it. The newly made viruses can then infect other local tumor cells, or travel through the bloodstream to infect metastasized(3) tumor cells in other parts of the body, and destroy them too.

Additionally, the use of these viruses in this process may hyper-stimulate a body's immune response. Heightened targeted immune response might lead to the body being able to fight its own cancer.

What could go wrong?

Mutation ... that's what!

Don't let this happen to you!
At least she doesn't have herpes.

OPPORTUNITY FOR MUTATION
During viral reproduction a lot of genetic coding is interrupted, replicated, inserted and re-replicated. All of these steps for making copies of viral DNA mean that there is a lot of opportunity for MUTATION. Not just people cellular mutation, but viral mutation, too.

Look out! I Am Legend takes place in Manhattan in 2012!

Coming up next - more about viruses and what to expect in two years!

1. Here is a link to a pdf of the article Virotherapy As An Approach Against Cancer Stem Cells, by Camilla Ribacka and Akseli Hemminki. Highly entertaining. As I read it, I found myself wishing that I Am Legend's Dr. Krippin (Emma Thompson), the virologist to blame for the entire horror-to-come, had been given a couple of lines reflecting a glimmer of what was written here. It wouldn't have to be too complicated, just something to make her sound more knowledgeable.
2. There are actually a few different types of herpesvirus out there, like the one that causes chicken pox. But the joke is better if it appears that you have to acquire a sexually transmitted disease in order to cure your cancer. Ha ha!
3. Cancer cells that have spread to other parts of the body.

THE AMAZING FIBROBLAST!


On Tuesday, I had the pleasure of giving a presentation at Adult Education: a useless lecture series. Carrie McLaren, Jim Hanas, and Charles Star curate, produce, and host this really fun monthly lecture presentation in Brooklyn.

The theme of the evening was Animal Minds, Animal Bodies. Keeping our mutation theme going, my contribution was a live version of my May 2009 Spider Palm entries from this blog. Here's the link, if you'd like to check out the description of Peter Parker's physical transformation.

Next time we will continue with mutation via the film I Am Legend!

KEVIN GEEKS OUT - Mutants #3

Me explaining hereditary mutations in Part 1 of my lecture.

THE INEVITABLE OVERTHROW OF THE HUMAN POPULATION,
DUE TO NOTABLE AND SIGNIFICANT INCREASES
IN ABERRANT CHROMOSOMAL PROLIFERATION OF MULTIPLE ETIOLOGIES
Part 3

From my Cinematologist lecture at Kevin Geeks Out: Visions Of The Future

Where were we? Oh, yes! In my last installment I had talked about inherited mutations, as documented above. Now we're on to acquired mutations....

Acquired mutations occur in the DNA of individual cells at some time during a person’s life.


Blonsky and Banner were not born this way, they were exposed to gamma radiation in adulthood.


Blonsky and Banner from The Incredible Hulk.


Notice Blonsky’s exaggerated cervical spinous processes.


Acquired mutations cannot be inherited. For example, skin cancer is caused by UV rays mutating genes in the skin, but if you have skin cancer lesions when you get pregnant, your baby isn’t born with skin cancer, he has to acquire it himself.


Sunshine


However, in order for the Hulk to pass on a genetic mutation, the sperm in his testicles would also have to be dosed with Gamma radiation. If Bruce Banner had held a lead apron over his testicles, his children would most likely be normal. If he wasn’t wearing an apron it is still impossible to predict HOW this altered genetic information will be expressed.


How will he express himself?


Additionally, having sex in either of his forms would not affect genetic expression.


Did he cover his testicles?


In 2084 When we set up colonies on Mars, mutation will advance by leaps and bounds. Thanks to miracles in modern science, acquired mutations due to inadequate radiation protection will become inheritable and PREDICTABLE, as demonstrated in the movie, Total Recall.

This girl has inherited a mutation

that her mother acquired!

However, according to films that afford us a vision of the future, disfigured mutants will not be valued by mainstream populations as deserving of respect. Additionally, reproductive success and the passing on genetic information requires that you find someone willing to have sex with you. Finding a reproductive partner is not a guarantee. It might be harder for some mutants...


If a woman married George/Kuato,

would she be guilty of polygamy?

... than for others!

This mutation may be successfully passed

along to future generations.


Which mutant species will dominate the planet? Which mutagens will be the downfall of humankind? What are the chances of human survival in the future? These are difficult questions. But if there is anything to be learned by scientific investigation it is this: In the future, as now…


Love will find a way!


Thus ends my Kevin Geeks Out lecture. Next time we plumb the viral depths of I Am Legend!

KEVIN GEEKS OUT - Mutants #1

THE CINEMATOLOGIST LIVE
A couple weeks ago I presented a lecture on mutations in the variety show Kevin Geeks Out. The theme of the evening was Visions Of The Future! My contribution was to describe the future mutations of human kind that will eventually and inevitably happen, as predicted by many futuristic movies.

Happily, the show was sold out, so some local readers (sadly) didn't get a chance to see the show. I thought I'd post a version of my lecture here. Check out the link to KGO, below. There were some really great guests! I was lucky to be among such esteemed company. Plus, they served Dippin' Dots!


Here's the first installment of my presentation. You'll notice that there are some style changes from the usual blog entries. There is much less text and many more pictures. It turns out that blogging and public speaking require different writing styles.

THE INEVITABLE OVERTHROW OF THE HUMAN POPULATION,
DUE TO NOTABLE AND SIGNIFICANT INCREASES IN
ABERRANT CHROROMOSOMAL PROLIFERATION OF MULTIPLE ETIOLOGIES(1)

In our examination of The Future, it is important to consider what will happen to the human species on a molecular level as we navigate an undending seires of collisions between meddling scientists and naturally occuring events.

The future is soon! As a matter of fact, according to some film sources, actions that will shape the future are happening right now!




Chemical wastes, various forms of radiation, and viruses are just a few of the mutagens acton on our genes. At any moment we should expect to hear about a variety of mutant groups and sub-groups emerging into our public awareness.

Future mutation may be the result of genetic engineering, as with Rachel from Blade Runner...

... or chaotic accident, perhaps instigated by a genetically engineered measles virus run amok on human populations(2).

I Am Legend is about genetically
engineered measles viruses in the future.

Therefore, our discussion of the future will examine the inevitable mutation of human beings into monstrous future super-species. So let's get down to the mutation breakdown.

A mutant organism is the result of a genetic mutation. What is a mutation? The alteration of genes, chromosomes, or DNA (more on that later).

Some mutations of the future will be bad for you but won't cause an external variation in appearance. An example would be a genetic blood disorder like hemophilia. Alexei Nicholaevich, son of Tsar Nicholas II was a hemophiliac. He is pictured here in a still from the movie Nicholas and Alexandra.

Hemophilia in the movies.

Some mutations will cause altered external appearance and will be bad for you too. An example here is a series of mutations caused by viral vampirism in Daybreakers.

Drink your human blood. Don't let this happen to you!

In the present and the future, some mutations or variations in DNA may influence the risk of developing the risk of developing certain disorders like Alzheimer's disease.


Some mutations won't help or harm you physically, like a generalized hypertrichosis a.k.a. Wolfman disease. Here is Robert Downey Jr. acting hypertrichosis for the camera.


Some genetic mutations change appearance and give your super-human skills. Here we see Hank McCoy's altered appearance as a result of mutation.

Exuberant hair + superhuman strength + blue pigment


What is the difference between chromosomes, genes, and DNA? Stay tuned(3) for the next installment of my lecture from Kevin Geeks Out: Visions Of The Future!


1. Yes, this really was my title.
2. We are so coming back to I Am Legend in a couple of weeks. There's a gold mine of mutation information here!
3. I just dated myself, didn't I?

KEVIN GEEKS OUT - Mutants #2

Me introducing future variations of genetic mutation.
Thanks, Matthew Glasson, for this great photo!


In our last/first installment of my lecture at Kevin Geeks Out, I had just laid some mutation groundwork, based on favorite mutation films. Here in Part 2 we continue our exploration of mutations, with a look at DNA, chromosomes, and genes...

THE INEVITABLE OVERTHROW OF THE HUMAN POPULATION,
DUE TO NOTABLE AND SIGNIFICANT INCREASES IN ABERRANT
CHROMOSOMAL PROLIFERATION OF MULTIPLE ETIOLOGIES

Part 2

What is the difference between chromosomes, genes and DNA?


A chromosome is a bunch of tightly coiled and packed together DNA,

DNA

the DNA is your genetic material.


Genes are sections of coiled DNA in the chromosome.

A mutation occurs when a gene's DNA is altered. What the heck is DNA? Deoxyribonucleic acid, that what. It's made of stuff called nucleotides. A genetic mutation occurs when DNA in a cell’s gene is damaged or altered in a way that changes the information carried by that gene.


DNA does two things. First, it reproduces itself before a cell divides, in an asexual process called mitosis.


Here in this aesexual pornographic image (below), we see the cell dividing. DNA reproduction gives each cell the same genetic information.



DNA also instructs cells to build proteins, which is a big deal. Proteins have the most varied functions of any molecules in the body. One of the things they do is to form the altered cell structures of the mutated Emil Blonsky and Bruce Banner.


Mutant proteins in mortal combat.


Mutations of the present and future can happen in two different ways, either inherited from a parent, or acquired during a person's lifetime.


Mutations that are passed from parent to child are called hereditary mutations. They are present in the egg and/or sperm cells. The X-Men mutations are excellent examples of hereditary mutations. This type of mutation is present throughout a person’s life in virtually every cell in the body. They may be passed on to offspring, sometimes predictably, or in the case of the Brotherhood of Evil, unpredictably.


The slang term for Mystique’s hereditary mutation is “shape shifting.” She can create ovaries or testes, at will, as she transforms into a male or female person. We should assume that she has viable reproductive cells regardless of their external form (egg or sperm). The predictability of mutant genetic expression is unexplored territory, requiring further research. At this point in time we must consider genetic expression in mutant offspring to be always unpredictable.

What about the sex lives of humans with acquired mutations? Come back for the third installment of my lecture from Kevin Geeks Out: Visions Of The Future!
