YouTube Summary: Our genetic information contains an "instruction booklet" of how to make up all the components in our body. But when these instructions are interpreted the wrong way—or gene regulation goes awry—it can cause many diseases, including cancer. In the follow up video to this month's Expert on the Spot, Prof. Chaim Cedar, of the Department of Developmental Biology and Cancer Research at the Faculty of Medicine, answers your questions about the role of gene regulation in cancer.

For those of you with short attention spans, we've set out a brief summary of the topics addressed by Prof. Cedar. Enjoy!

00:25 Role of gene regulation in cancer; 01:30 Are certain cancers more genetic than others; 04:00 What other cancer treatments are there in addition to radiation; 06:15 Is cancer genetic or is it caused by exposure to environment/carcinogens; 08:10 Will a future DNA or biotechnology development cure cancer; 10:15 Is there any way to "turn on" specific genes; 12:00 Does every cell in body contain all of a person's DNA.

  • 00:28 Gene Regulation

    Cannabinoid Receptors (CB1 & CB2) are in our skin, brain, immune system, intestines, liver, spine, ribs, white blood cells, & bone marrow (STEM CELLS) etc. Without the 600+ Million year old Endocannabinoid System*, Stem Cells would act like a car without a driver.

    *Dr. Guy, Executive Chairman of GW Pharmaceuticals, London, UK

  • 1:37 Colon Cancer

    -"THC is excellent for treating Crohn's disease & things of that sort."

    Dr. Mechoulam

    -"Cannabinoids cool the intestine", PMCID: PMC2516444

    -University of Bristol, UK, "THC induces apoptosis in colorectal Cancer cells." PMID: 17583570

    -"The Cannabinoid system could provide a new therapeutic target for treatment of gastro. diseases, nausea, vomiting, gastric ulcers, secretory diarrhoea, paralytic ileus, IBD, COLON CANCER and gastro-oesophageal reflux conditions."

    PMID: 16596788

  • 2:52 More protected from Cancer

    "From my opinion, once you realize the magnitude of the impact that cannabis has in a positive sense for most people most of the time, on our biochemistry. It should really be considered a food and an essential nutrient. .. Cannabis is always involved in all those different things because it involves the immune system, the digestive system, cardiovascular system, skin, nervous system, endocrine system, essentially it is involved in everything."

    Dr. Melamede

  • 4:10 Treat Cancer

    -United Kingdom, Dr. Liu, "Cannabis destroys Cancer Cells"

    -United States, Dr. Melamede, "Cannabinoids kill Cancer Cells"

    -Italy, Dr. Di Marzo, "THC exhibits anti - tumor effects on various Cancer Cell types"

    -Spain, Dr. Guzman, "THC can promote the autophagic death of human & mouse Cancer Cells"

    -Israel, Dr. Mechoulam, "we gave THC oil drops 400 times to children 1 -13 years old with Cancer & prevented vomiting & nausea 100%"

  • 6:15 Breast Cancer

    "Dr. Di Marzo's group found that Cannabinoids inhibit breast Cancer cell proliferation, and Dr. Guzman's group found that Cannabinoids inhibit the growth of C6 glioma cell."

    PMID: 16250836

    "Breast and prostate Cancer cells are also sensitive to Cannabinoid-induced antiproliferation. Regarding the immune system, low doses of Cannabinoids may enhance cell proliferation, whereas high doses of Cannabinoids usually induce growth arrest or apoptosis."

    PMID: 11269508

  • 6:50 Initiate Cancer

    Antiperspirants block the underarm Apocrine sweat gland called the Axilla. Once the Axilla is blocked the next closest Apocrine sweat gland is the Areola located around the nipple! Composition of Apocrine sweat: Thick, milky fluid, excretions include protein, ammonia, lipids, chromogranins (family of proteins). Apocrine sweat gland obstruction = Initiation of Breast Cancer.

    PMID: 16045991, PMID: 19307063 & PMID: 17629949

  • 8:40 Invest in basic research

    -In 1839, Homeopathy journal American Provers' Union publishes first of many reports on the effects of Cannabis

    -In 1860, First Governmental commission study of Cannabis and health conducted by Ohio State Medical society.

    -In 1870, Cannabis is listed in the US Pharmacopoeia as a medicine for various ailments, dropped in 1941.

    THC (Rick Simpson's Cancer Cure Hemp Oil) achieves this wizardry by binding to protein receptors on a cancerous cell's surface. Once attached the THC induces the cell to make a fatty substance called ceramide, which prompts the cell to start devouring itself. "We see programmed cell death" Velasco says. What's more, noncancerous cells don't make ceramide when they come into contact with THC. The healthy cells don't die.

    Biochemists Guillermo Velasco & Manuel Guzmán, Spain

  • 11:02 Known for a long time

    Dr. Mechoulam has been researching Cannabinoids (Cannabis) since 1960 - present.

    11:20 Using this drug wrongly

    "The minute you take a Marijuana joint & light it on fire over 90% of the medicinal aspects of that plant just went up in smoke. But when you eat the raw unburnt THC then MAGIC happens."

    Rick Simpson
