Ivermectin cancer PAK1 oncogene oncogenes

shared by Nathan Goodyear on 21 Mar 18 - No Cached
  • 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.
  • PAK-1 kinase is required for the growth of more than 70% of human cancers such as pancreatic, colon, breast and prostate cancers, and neurofibromatosis
  • ...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.
  • Praziquantel , my other favorite parasite medication for liver flukes, synergistically enhances Paclitaxel (Taxol) efficacy to inhibit cancer cell growth

    PAK1 is an oncogene. Here that is linked to genesis of breast cancer through the RAS-RAF-MEK-ERK-MAPK pathway. Ivermectin, a common anti-parasitic, is know to block this oncogene activity.

Ivermectin cancer

  • The avermectins are known to possess pronounced antitumor activity
  • Over the past few years, there have been steadily increasing reports that ivermectin may have varying uses as an anti-cancer agent, as it has been shown to exhibit both anti-cancer and anti-cancer stem cell properties
  • In human ovarian cancer and NF2 tumor cell lines, high-dose ivermectin inactivates protein kinase PAK1 and blocks PAK1-dependent growth
  • ...13 more annotations...
  • PAK1 is essential for the growth of more than 70% of all human cancers, including breast, prostate, pancreatic, colon, gastric, lung, cervical and thyroid cancers, as well as hepatoma, glioma, melanoma, multiple myeloma and for neurofibromatosis tumors
  • Ivermectin suppresses breast cancer by activating cytostatic autophagy, disrupting cellular signaling in the process, probably by reducing PAK1 expression
  • Cancer stem cells are a key factor in cancer cells developing resistance to chemotherapies and these results indicate that a combination of chemotherapy agents plus ivermectin could potentially target and kill cancer stem cells, a paramount goal in overcoming cancer
  • Triple-negative breast cancers, which lack estrogen, progesterone and HER2 receptors, account for 10–20% of breast cancers and are associated with poor prognosis
  • Ivermectin addition led to transcriptional modulation of genes associated with epithelial–mesenchymal transition and maintenance of a cancer stem cell phenotype in triple-negative breast cancers cells, resulting in impairment of clonogenic self-renewal in vitro and inhibition of tumor growth and metastasis in vivo
  • Ivermectin-induced cytostatic autophagy also leads to suppression of tumor growth in breast cancer xenografts, causing researchers to believe there is scope for using ivermectin to inhibit breast cancer cell proliferation and that the drug is a potential treatment for breast cancer
  • ivermectin synergizes with the chemotherapy agents cytarabine and daunorubicin to induce cell death in leukemia cells
  • Ivermectin inhibits proliferation and increases apoptosis of various human cancers
  • Activation of WNT-TCF signaling is implicated in multiple diseases, including cancers of the lungs and intestine,
  • A new screening system has found that ivermectin inhibits the expression of WNT-TCF targets
  • It represses the levels of C-terminal β-catenin phosphoforms and of cyclin D1 in an okadaic acid-sensitive manner, indicating its action involves protein phosphatases
  • In vivo, ivermectin selectively inhibits TCF-dependent, but not TCF-independent, xenograft growth without side effects
  • ivermectin has an exemplary safety record, it could swiftly become a useful tool as a WNT-TCF pathway response blocker to treat WNT-TCF-dependent diseases, encompassing multiple cancers.117

    Ivermectin shows promise and usefullness in several cancer types.  This is a review article.
