  5. In the fight against disease, programmed cell death – also known as #apoptosis – is a key protective function of the body. It breaks down cells that are damaged or have undergone dangerous changes.

  7. Trying to think of a better phrase than "AI Bubble".
    How about "AIpoptosis"?
    Really depends on anything useful being left behind!

    Wikipedia, Apoptosis

    In contrast to necrosis, which is a form of traumatic cell death that results from acute cellular injury, apoptosis is a highly regulated and controlled process that confers advantages during an organism's life cycle. For example, the separation of fingers and toes in a developing human embryo occurs because cells between the digits undergo a form of apoptosis that is genetically determined. Unlike necrosis, apoptosis produces cell fragments called apoptotic bodies that phagocytes are able to engulf and remove before the contents of the cell can spill out onto surrounding cells and cause damage to them.

  12. I'm extracting DNA from the legs of spiders which were euthanized by freezing in a household freezer. In almost every spider, the DNA shows a banding pattern associated with apoptosis. Why would there be so much programed cell death in the legs of spiders? Had it already happened naturally? Was it induced during the freezing process? I do not see this happening in other organisms using the same extraction procedure.

    Each lane is DNA extracted from a different spider.

  27. #Marijuana Extract Can Kill #Melanoma Cells, New Study Reveals Possible Treatment For #SkinCancer

    Story by Nina Zdinjak

    February 8, 2024

    "A new study indicates #cannabis has the potential to treat melanoma, a skin cancer beginning in the melanocyte cells, which make the pigment that gives skin its color.

    "Melanoma typically results from over-exposure to the sun. While skin cancer is one of the most common cancers in the United States, melanoma accounts for only about 1%, yet causes a large majority of skin cancer deaths, according to the American Cancer Society.

    "New research published in a peer-reviewed Cell Journal conducted by scientists from Charles Darwin University (CDU) and RMIT University offers hope for the creation of a natural treatment for melanoma.

    "The study, part of a Ph.D. project by RMIT's Dr. Ava Bachari, showed that a specific cannabis extract (#PHEX66) from the #CannabisSativa plant binds to receptor sites on particular melanoma cells, controlling its growth at two key phases and increasing the amount of damage to these cells.

    "Dr. Nazim Nassar, the study co-author and CDU pharmaceutical lecturer said this damage practically tricks cells into killing itself, writes Mirage News. This inhibitory effect arises from interactions with #CB1 and #CB2 receptors, the paper reads.

    "'The damage to the melanoma cell prevents it from dividing into new cells, and instead begins a programmed cell death, also known as #apoptosis,' Dr. Nassar said. 'This is a growing area of important research because we need to understand cannabis extracts as much as possible, especially their potential to function as anticancer agents. If we know how they react to cancer cells, particularly in the cause of cell death, we can refine treatment techniques to be more specific, responsive and effective'.

    "According to Nassar, who specializes in cancer cell biology, pharmacology and drug delivery systems, the next step should be to create a targeted delivery system for the melanoma cells in preparation for pre-clinical trials.

    "'Clinical uses of cannabis extracts include treatment for anxiety, cancer-related symptoms, epilepsy, and chronic pain. Intensive research into its potential for killing melanoma cells is only the start as we investigate how this knowledge can be applied to treating different types of cancers,' Nassar said.

    "Professor Nitin Mantir, lead author and RMIT biotechnologist, said there needs to be a thorough follow-up to assess the long-term efficiency and safety of the PHEC-66 extract.

    "'The subsequent stage involves animal studies or pre-clinical trials to validate and further explore the efficacy of cannabinoid PHEC-66 in treating melanoma and other cancers,' Mantri said.

    "Both authors stressed the need for support and sponsorship to eventually qualify PHEC-66 as a registered medicine."

    When this happens, fraudsters usually claims honest error, but in this case, the conclusions have been proven false: in #Alzheimer's disease, APP - the precursor of amyloid beta - does not bind in the way suggested to DR6 - a receptor that induces neuronal #Apoptosis- and everything in that paper is a lie.

    "They propose that early protoeukaryotes were predators, relying on bacterial prey. These bacteria, in response to predation, produced toxins as a defense mechanism. Over time, these bacteria were domesticated to serve as mitochondria within eukaryotic cells, and their toxins evolved into apoptotic factors. "
