TOBACCO AND LUNG CANCER….. THE SMOKING GUN FOUND
FROM THE DVDs on “genetic” from the TEACHING COMPANY
GENES AND DNA
DAVID SADAVA PhD
GENES IN THE CELL
THEN NUCLEUS PART OF CELL
THEN IN THE CHROMOSOMES PART OF NUCLUS
THEN WE FIND PAY DIRT—— DNA!
ERNEST WYNDER (1923-1999) WAS A STUDENT AT WASHINGTON UNIVERSITY IN ST. LOUIS.
A MAN DIED OF LUNG CANCER.
OPENING UP HIS BODY WYNDER SAW THE LUNGS WERE BLACK!
HE HAD SMOKED 2 PACKS A DAY FOR LAST 35 YEARS OF HIS LIFE.
COULD THERE BE A LINK BETWEEN LUNG CANCER AND SMOKING?
200 YEARS BEFORE - EUROPEAN STUDIES SAID THERE WAS A LINK BETWEEN SMOKING AND LUNG
CANCER.
PUBLICATIONS IN THE 1600s IN ENGLAND SAID SO!
“SNUFF” - SNUFFING-UP TOBACCO CAUSED THROAT CANCER ETC.
WYNDER DID A CASE CONTROL STUDY.
HE COMPARED 600 PEOPLE WHO DIED OF LUNG CANCER WITH 600 PEOPLE OF SIMILAR AGE ETC. WHO DID NOT DIE OF LUNG CANCER.
LUNG CANCER WAS 40 TIMES GREATER IN SMOKERS!
THIS APPROACH IS CALLED EPIDEMIOLOGY, THE MEDICAL STUDY OF THE STATE OF DISEASE AND “NOT DISEASE” IN A POPULATION.
AT THE SAME TIME IN EARLY 1950s DR. DOLL (1912-2005) FOLLOWED OVER A LONG TIME DOCTORS WHO SMOKED AND DID NOT
SMOKE.
DOLL FOUND FAR MORE DOCTORS WITH LUNG CANCER WHO SMOKED.
GOT TO REMEMBER BACK THEN PEOPLE THOUGHT IT WAS A RELAXING PASS-TIME TO SMOKE, HELP TO CALM STRESS.
BUT ALL THIS STUDY HAS PROBLEMS: GOOD OF BAD GENERAL HEALTH, FOODS EATEN, EXERCISE MORE OR LESS ETC.
SO STILL DOUBTS! WELL TO A POINT.
IN THE 1990s - CAME INCONTROVERTIBLE EVIDENCE BETWEEN LUNG CANCER AND
SMOKING WAS FOUND!
CANCER IS DAMAGE TO A GENE.
A GENE CALLED P53 GETS PERMANENTLY CHANGED (MUTATED OR MUTATION)
MUTATION IS A PERMANENT CHANGE TO A GENE - PASSED ON TO THE NEXT
GENERATION.
IF MUTATION HAPPENS IN SPERM OR EGG THE OFFSPRING WILL INHERIT
THEM.
IF MUTATIONS HAPPEN IN ANY OTHER CELL OF THE BODY THEY ARE
“SOMATIC MUTATIONS” - NON-SEX CELLS.
THE P53 GENE WAS MUTATED ALONG THE STRAND OF DNA - AT CERTAIN SPOTS - KNOWN AS “HOT SPOTS.”
IN THE EARLY 1990s TOBACCO SMOKE WAS ANALYZED BY SOPHISTICATED
MACHINES - THERE ARE 100s OF MOLECULES IN TOBACCO SMOKE.
ONE MOLECULE WAS BP [BENZOPYRENE]
IN THE LUNG BP IS CONVERTED TO A VERY HIGH ACTIVE MOLECULE - WILL REACT WITH ANOTHERS VERY EASILY AND BECOMES BPDE.
BPDE BINDS TO AND DAMAGES OTHER GENES.
BPDE IS FROM SMOKE - IT BINDS TO P53 GENE AND CHANGING P53 - IT WAS FOUND RIGHT AT THE “HOT SPOTS” IN LUNG CANCER.
THIS FINDING CLOSED THE CIRCLE OF EVIDENCE FOR SMOKING AND LUNG
CANCER.
IT WAS NO LONGER “DOUBTFUL” AS IN EPIDEMIOLOGY.
THIS WAS SOLID EVIDENCE!
P53 GENE IS MADE OF DNA, BUT NOW WRONG DNA!
HUMANS HAVE 24,000 GENES.
WE ARE 70 PERCENT WATER - NO STORAGE OF INFORMATION IN WATER.
BUT 24,000 GENES HAVE VAST VAST, AND VAST AMOUNTS OF STORAGE
INFORMATION.
ALL STORED IN DNA [WHICH STANDS FOR A CERTAIN SCIENTIFIC NAME
WHICH SCIENCE IS FAMOUS FOR STRANGE NAMES]
A GENE THAT ENDS UP WRONG—— TROUBLES
SMOKING WAS NOW PROVED IT CAN DAMAGE A GENE, DAMAGE NORMAL DNA AND HOW IT HOLDS CORRECT INFORMATION WHICH NOW BECOMES
INCORRECT INFORMATION.
DNA CAN BE AFFECTED BY THINGS ON THE OUTSIDE.
ALL NORMAL DNA WORKS TO MAKE YOU WANT YOU ARE - COLOR OF HAIR, COLOR OF EYES, YOUR EVENTUAL HIGHT, AND SO ON.
IF BAD ENVIRONMENT AND FOOD EATING, YOUR DNA HIGHT SAYS YOU
SHOULD BE 5 FEET 10 INCHES, BUT OUTSIDE AFFECTS YOU END UP
5 FEET 4 INCHES.
SMOKING AND THE P53 GENE WITH NOW BPDE - P53 GENE AND IT CHANGING AT THE HOT SPOTS.
WELL IT ALL PROVED SMOKING AND LUNG CANCER CONNECTED!
THERE WAS NO MORE DOUBTING THAT SMOKING COULD CAUSE LUNG CANCER!
………………..
OF COURSE WE ALL KNOW OF PEOPLE WHO SMOKED ALL THEIR ADULT
LIFE AND LIVED TO BE IN THEIR 90s OR EVEN 100.
THERE ARE EXCEPTIONS TO JUST ABOUT ANY NORM OR RULE; FOR MANY MANY REASONS, WE MAY NOT KNOW THE TECHNICAL “WHYS” OF IT ALL, BUT THEY ARE THE FEW RARE EXCEPTIONS.
AS A KID GROWING UP AND GETTING TO ABOUT AGE 14/15/16 A FEW [NOT VERY MANY BACK IN THE 1950s] SOME OF THE GUYS IN HIGH SCHOOL
STARTED TO SMOKE, AND THEY WERE PRETTY GOOD ATHLETES UP TO
THE TIME OF THEM SMOKING. WE WOULD HAVE OUR SPORTS RUNNING
PRACTICES, AND SOCCER PRACTICES----- [WHERE YOU DO LOTS OF RUNNING]. THE SMOKERS WOULD VERY SOON
BE PUFFING AND PANTING. I REMEMBER VERY WELL SOME OF THEM FINALLY SAYING QUITE OUT LOUD— “O MY I JUST CAN’T DO THIS AS WELL AS I COULD; I JUST HAVE TO GIVE UP SMOKING!”
THE PROOF OF THE CAKE IS IN THE EATING.
IT WAS JUST A KNOWN FACT AMONG US TEEN LADS THAT SMOKING WAS
NOT GOOD FOR YOU.
IT WAS JUST THAT SIMPLE— PERIOD!
WHEN YOU READ ABOUT THE “DOUBTERS” IN THIS PAST STUDY, IT IS
LAUGHABLE TO SOMEONE LIKE ME; I COULD HAVE TOLD EVERYONE WAY BACK IN THE 1950s THAT TOBACCO SMOKING WAS UNHEALTHY FOR YOU,
AND IF YOU VALUED YOUR HEALTH YOU WOULD NOT SMOKE
TOBACCO.
