rsp<p>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?

Synergistic Anti-Cancer Potential of Phenethyl Isothiocyanate and Curcumin Induces Apoptosis and G2/M Cell Cycle Arrest in HER2-Positive Breast Cancer Cells - #phenethylisothiocyanate #curcumin #apoptosis #HER2 #breastcancer #etc - link.springer.com/article/10.3

SpringerLinkSynergistic Anti-Cancer Potential of Phenethyl Isothiocyanate and Curcumin Induces Apoptosis and G2/M Cell Cycle Arrest in HER2-Positive Breast Cancer Cells - Cytology and GeneticsAbstract HER2 expression is associated with 30% of breast cancer patients with a poor prognosis. Though Trastuzumab is approved for HER2 targeted therapy, its use is limited because of its systemic toxicity and resistance in most patients. This study evaluated the synergistic effects of Phenethyl isothiocyanate (PEITC) and Curcumin (CUR) in HER2 overexpressing SK-BR-3, BT-474, and AU-565 breast cancer cells. The cytotoxic effect of PEITC : CUR against breast cancer cells was evaluated using an MTT assay, and the Loewe additivity model was used to evaluate the synergistic effect. Apoptosis induction and cell cycle arrest over the treatment of PEITC: CUR in breast cancer cells were examined using the flow cytometric annexin-V/Propidium iodide method. Downregulation of HER2-mediated signaling was deduced from protein expression analysis using western-blot. Our results showed that treatment of PEITC : CUR at varying levels of combinations in all three breast cancer cells extensively reduced the survival of the cells with the lowest inhibitory concentrations (IC50). Cytotoxic data revealed that the 3 : 1 ratio of PEITC : CUR was the best among several (1 : 1, 3 : 1, and 1 : 3) combinations, with the maximum cytotoxicity. PEITC : CUR (3 : 1) displayed the lowest combination index (CI) against SK-BR-3, and AU-565 cells indicated its potential synergistic effect. At twice the concentration of its IC50, the 3 : 1 combination elicited 3.5 to 4.5 fold apoptosis in HER2 overexpressing cells, approximately double the effect of the individual drugs alone. In addition, the selected combination induced the G2/M cell cycle arrest in HER2 expressing cells over the treatment. Western blot protein expression analysis revealed that the PEITC : CUR combination suppressed the HER2/PI3K/Akt signaling, eventually connected to various apoptotic biological events. Our results showed the specificity of PEITC: CUR combination in inducing apoptosis and G2/M cell cycle arrest in HER2-expressing tumor cells in-vitro and enhancing the anti-cancer effect. For a subset of breast cancer patients who overexpress HER2, this combination of PEITC and CUR could be a potential treatment option.

#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."

#cancer#HIV#health

Існує чудовий природний механізм регульованого (мозком) та програмованого (!!!) знищення клітин організму. Чудовість його, на мій погляд, у тому, що самознищення клітин відбувається так, що знищується навіть генетичний матеріал.
Що в цьому чудового? Уявіть, що Ви (Ваш мозок) можете знищити будь-які клітини свого організму, в яких з тієї чи іншої причини порушився оригінальний порядок ДНК/РНК.

Повернемося до чогось цікавішого, перспективнішого та реалістичнішого ніж спроби знайти роботу))
У мене ще залишилося кілька днів на те, щоби поділитися деякими ідеями.
Відразу попереджаю, спроби реалізувати, те, що я збираюся описати, можуть бути небезпечними і можуть зашкодити здоров'ю, можуть призвести навіть до смерті. Тому, якщо Ви не впевнені – у жодному разі не робіть цього.
