  • The activation of each of them leads to an inhibition of adenylyl cyclase via G proteins (Gi/o), which in turn activates many metabolic pathways such as mitogen‐activated protein kinase pathway (MAPK), phosphoinositide 3‐kinase pathway (PI3K), cyclooxygenase‐2 pathway (COX‐2), accumulation of ceramide, modulation of protein kinase B (Akt), and ion channels
  • phytocannabinoids, endocannabinoids, and synthetic cannabinoids
  • Action of THC in human organism relies on mimicking endogenous agonists of CB receptors—endocannabinoids
  • ...8 more annotations...
  • The upregulated expression of CB receptors and the elevated levels of endocannabinoids have been observed in a variety of cancer cells (skin, prostate, and colon cancer, hepatocellular carcinoma, endometrial sarcoma, glioblastoma multiforme, meningioma and pituitary adenoma, Hodgkin lymphoma, chemically induced hepatocarcinoma, mantel cell lymphoma)
  • concentration of endocannabinoids, expression level of their receptors, and the enzymes involved in their metabolism frequently are associated with an aggressiveness of cancer
  • CB2 receptor contributes to human epidermal growth factor receptor (HER2) pro‐oncogenic signaling and an overexpression of CB2 increases susceptibility for leukemia development after leukemia viral infection
  • endocannabinoid‐degrading enzymes are upregulated in cancer cell lines and in human tumors
  • Many cannabinoids, ranging from phytocannabinoids (THC, CBD), endocannabinoids (2‐arachidonoylglycerol, anandamide), to synthetic cannabinoids (JWH‐133, WIN‐55,212‐2), have shown ability to inhibit proliferation, metastasis, and angiogenesis in a variety of models of cancer
  • Despite some inconsistent data, the main effect of cannabinoids in a tumor is the inhibition of cancer cells’ proliferation and induction of cancer cell death by apoptosis
  • CB1 and CB2 receptor agonists stimulate apoptotic cell death in glioma cells by induction of de novo synthesis of ceramide, sphingolipid with proapoptotic activity
  • process of autophagy is upstream of apoptosis in mechanism of cell death induced by cannabinoids

  • Ivermectin can inactivate the protein kinase PAK1 and blocks the PAK1-dependent growth of human ovarian cancer and NF2 tumor cell lines
  • PAK proteins encoded by the PAK1 gene are critical for cytoskeleton reorganization and nuclear signaling.

  • ...5 more annotations...
  • The p21 activated Kinase PAK1 is implicated in tumor genesis.
  • Inhibiting PAK1 signals induce tumor cell apoptosis (cell death)
  • PAK1 has also been implicated for maintenance of glucose homeostasis in pancreatic beta cells and skeletal muscle
  • Ivermectin induces chloride-dependent membrane hyperpolarization and cell death in leukemia cells (Blood, November 4, 2010, vol.115). The paper states Ivermectin synergizes with chemo agents cytarabine and daunorubicin to induce cell death in leukemia cells.

    ER beta and prostate cancer.  More aggressive prostate cancer is found to be associated with lower ER beta expression in the prostate.  this makes sense, as other studies have shown that ER beta in the prostate can induce apoptosis (cell death), which is a powerful mechanism to regulate uncontrolled growth as found in cancer.

  • studies have demonstrated that the shortest telomeres are causal of reduced cell viability
  • a stable and enforced expression of telomerase leads to an improved health-span, accompanied by an extension of lifespan
  • TA-65 influences the percentage of cellular short telomeres through the activation of telomerase
  • ...17 more annotations...
  • TA-65 administration during 4 months significantly improved the capacity to uptake glucose after a glucose pulse
  • liver protective action of TA-65
  • A disadvantage of mTERT potentiation could be associated to its capacity to favor proliferation of cancerous cells in murine models
  • TA-65 treated mice presented a similar incidence of malignant cancers at time of death, with a tendency to show decreased sarcomas and slightly increased lymphomas
  • We demonstrate here that TA-65 leads to a significant rescue of short telomeres through telomerase activation
  • TA-65 treatment increases proliferation and mobilization potential of mouse keratinocytes in vitro, a situation mimicking telomerase overexpression
  • TAT2, a similar molecule, have beneficial effects in the activation of CD8+ T lymphocytes from HIV-infected patients where they observe an increase of the proliferative potential and enhancement of cytokine/chemokine production
  • TA-65 resulted in a similar rescue of short telomeres in leukocytes post-treatment as observed with humans, most likely through an activation of telomerase
  • we observe that TA-65 lead to 10 fold increase of telomerase RNA levels in the liver of treated mice comparing to the non-treated same-age cohorts
  • TA-65 regulates telomerase at the transcription level, probably through the regulation of the MAPK pathway
  • TA-65 dependent telomerase activation results in a better organ fitness as demonstrated by the improved scores at the glucose tolerance test and insulin levels at fasting
  • TA-65 supplemented mice also present modest enhancement of the subcutaneous and epidermal thickness, as well as higher bone density, representative of an overall fitness status improvemen
  • TA-65 treated mice present higher levels of RBC and hemoglobin comparing to the control cohorts
  • improved health-span of TA-65 treated mice is not accompanied by increased cancer incidence, which may be related to the fact that TERT levels are very modestly increased in all tissues tested except for the liver
  • systemic telomerase overexpression from the germline leads to protection from aging associated pathologies
  • similar situation could be mimicked expressing telomerase late in life in a telomerase deficient background
  • we observed a higher proliferation rate and a partial protection from cell death in some tissues of TA65 treated mice
