Chen Y.P., Chan A.T.C., Le Q.T., Blanchard P., Sun Y., Ma J. Nasopharyngeal carcinoma. After treatment with IVM, the proliferation of multiple breast cancer cell lines including MCF-7, MDA-MB-231 and MCF-10 was significantly reduced. Dong Z., Yu C., Rezhiya K., Gulijiahan A., Wang X. Downregulation of miR-146a promotes tumorigenesis of cervical cancer stem cells via VEGF/CDC42/PAK1 signaling pathway. Fritz L.C., Wang C.C., Gorio A. Avermectin B1a irreversibly blocks postsynaptic potentials at the lobster neuromuscular junction by reducing muscle membrane resistance. Previous studies have indicated that PAK1 is located at the intersection of multiple signaling pathways related to tumorigenesis and is a key regulator of cancer signaling networks (Fig. Melotti A., Mas C., Kuciak M., Lorente-Trigos A., Borges I., Ruiz i Altaba A. Arcangeli S., Pinzi V., Arcangeli G. Epidemiology of prostate cancer and treatment remarks. In animal experiments, the immunohistochemical results for IVM-treated tumor tissues showed that the expression of the mitochondrial stress marker HEL was significantly increased, and the results were consistent with those of the cell experiments. IVM has also shown beneficial effects against other parasitic diseases, such as malaria [11,12], trypanosomiasis [13], schistosomiasis [14], trichinosis [15] and leishmaniasis [16]. In mid-2020, an ivermectin study published in the prestigious New England Journal of Medicine was retracted. The study found that patients with Covid-19 treated in hospital who "received ivermectin early reported substantial recovery" and that there was "a substantial improvement and reduction in . In addition, IVM regulated the expression of the epithelial mesenchymal-transition (EMT) related gene E-cadherin to restore the sensitivity of TNBC cells to tamoxifen, which implies the possibility that IVM functions as an epigenetic regulator in the treatment of cancer[36]. Based on the studies suggesting efficacy in prophylaxis combined with the known safety profile of ivermectin, a citywide prevention program using ivermectin for COVID-19 was implemented in Itaja, a southern . Inflammasomes initiate the conversion of pro-caspase-1 via self-shearing into activated caspase-1. IVM could inhibit the development of hepatocellular carcinoma by blocking YAP1 activity in spontaneous liver cancer Mob1b-/- mice [43].Cholangiocarcinoma is a malignant tumor that originates in the bile duct inside and outside the liver. Genetic and molecular epidemiology of adult diffuse glioma. Smit M.R., Ochomo E.O., Aljayyoussi G., Kwambai T.K., Abongo B.O., Chen T., Bousema T., Slater H.C., Waterhouse D., Bayoh N.M., Gimnig J.E., Samuels A.M., Desai M.R., Phillips-Howard P.A., Kariuki S.K., Wang D., Ward S.A., Ter Kuile F.O. The reason for the proclamation was the rise in the number Table 1, the main form of IVM induced programmed cell death is apoptosis. In another study, IVM inhibited the proliferation of U251 and C6 glioma cells by inhibiting the Akt/mTOR pathway [64]. A global view of hepatocellular carcinoma: trends, risk, prevention and management. In the past year, more than one million patients with gastric cancer have been diagnosed worldwide [38]. Safety, tolerability, and pharmacokinetics of escalating high doses of ivermectin in healthy adult subjects. After using the autophagy inhibitor bafilomycin A1 or siRNA to downregulate Beclin1, IVM-induced apoptosis was significantly enhanced, which suggested that enhanced autophagy will reduce IVM-induced apoptosis and that IVM-induced autophagy can protect tumor cells from apoptosis. 2 On the other hand, ivermectin promotes programmed cancer cell death, including apoptosis, autophagy and pyroptosis. This medicine is available only with your doctor's . It is intended as a sharing of knowledge and information from the research and experience of Dr. Mercola and his community. Doramectin--a potent novel endectocide. IVM can inhibit the replication of flavivirus by targeting the NS3 helicase [17]; it also blocks the nuclear transport of viral proteins by acting on /-mediated nuclear transport and exerts antiviral activity against the HIV-1 and dengue viruses [18]. Kumar R., Li D.Q. Cancer statistics, 2019. Targeting PAK1 is a novel and promising method for cancer treatment, and the development of PAK1 inhibitors has attracted widespread attention [111]. Therefore, we believe that the anticancer effect of IVM is not limited to cytotoxicity, but also involves the regulation of the tumor microenvironment. Ashour D.S. The clinical trials described in this table are RCTs that had the greatest impact on the Panel's recommendation. Dr. Mercola encourages you to make your own health care decisions based upon your research and in partnership with a qualified health care professional. Levy J.M.M., Towers C.G., Thorburn A. Gasdermin D(GSDMD)is a substrate for activated caspase-1 and is considered to be a key protein in the execution of pyroptosis [86,87]. Furthermore, Diaos study showed that IVM could inhibit the proliferation of the canine breast tumor cell lines CMT7364 and CIPp by blocking the cell cycle without increasing apoptosis, and the mechanism of IVM may be related to the inhibition of the Wnt pathway [33]. Recently, ivermectin, a well-known anti-parasite drug, was reported to share the same mechanisms with them and have anti-tumor activity. IVM induces different programmed cell death patterns in different tumor cells (Table 1). We believe that deeper exploration of the mechanism can further guide the use of IVM in the treatment of cancer. Following the study, the FDA released a letter out of concern warning consumers not to self-medicate with ivermectin products intended for animals. In research to screen potential targets for the treatment of ovarian cancer through the use of an shRNA library and a CRISPR/Cas9 library, the oncogene KPNB1 was detected. Ivermectin has been used off-label widely since the original in vitro study by Caly et al. The study was published January 10, 2022 in Clinical Cancer Research. A study published in this week's Journal of the American Medical Association ( JAMA) reported on a double-blind placebo controlled randomized trial of nearly 1600 adults with mild to moderate . IVM activates glutamate-gated chloride channels in the parasite, causing a large amount of chloride ion influx and neuronal hyperpolarization, thereby leading to the release of gamma-aminobutyric acid (GABA) to destroy nerves, and the nerve transmission of muscle cells induces the paralysis of somatic muscles to kill parasites [9,10]. In humans, the FDA has approved ivermectin to treat infections caused by some parasitic worms and, topically, for head lice and the skin disorder rosacea. Moreover, IVM was also found to have a good inhibitory effect on the prostate cancer cell line DU145 [51]. Loibl S., Gianni L. HER2-positive breast cancer. ). We use cookies to enhance your experience. EverythingIsFine . Interestingly, IVM could also show activity against BRAF wild-type melanoma cells, and its combination with dapafinib could significantly increase antitumor activity. treatment [[23], [24], [25], [26], [27]]. Glioblastoma is the deadliest glioma, with a median survival time of only 14-17 months [61,62]. However, to date, no exact target for IVM action has been found. Cancer stem cells and self-renewal. Here, we systematically summarized the anticancer effect and mechanism of IVM, which is of great significance for the repositioning of IVM for cancer treatment. Although CSCs are similar to stem cells in terms of function, because of the lack of a negative feedback regulation mechanism for stem cell self-renewal, their powerful proliferation and multidirectional differentiation abilities are unrestricted, which allows CSCs to maintain certain activities during chemotherapy and radiotherapy [[90], [91], [92]]. 1,553. On the other hand, caspase-1 activated by GSDMD triggers pyroptosis independent of apoptosis. But the study provides solid evidence that ivermectin is no better than a placebo when given at a dose of roughly 30 milligrams per day over a three-day interval. A longitudinal study was undertaken in three hyperendemic foci in Mali and Senegal with 15 to 17 years of annual or six-monthly ivermectin treatment in order to assess residual levels of infection . A Colombian health worker . Jiang L., Wang P., Sun Y.J., Wu Y.J. Identifying the predominant or most important contributor to cell death in each cancer type and environment will be crucial in determining the effectiveness of IVM-based treatments. Triple-negative breast cancer (TNBC) refers to cancer that is negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2(HER2) and is the most aggressive subtype of breast cancer with the worst prognosis. Furthermore, according to a report by Zhang, IVM can enhance the efficacy of cisplatin to improve the treatment of epithelial ovarian cancer, and the mechanism is related to the inhibition of the Akt/mTOR pathway [60]. There are still some problems that need to be studied and resolved before IVM is used in the clinic. ). The FDA-approved drug . Kim J.H., Choi H.S., Kim S.L., Lee D.S. Since January 2020 Elsevier has created a COVID-19 resource centre with free information in English and Mandarin on the novel coronavirus COVID-19. Ovarian cancer is a malignant cancer that lacks early clinical symptoms and has a poor therapeutic response. Goudie A.C., Evans N.A., Gration K.A., Bishop B.F., Gibson S.P., Holdom K.S., Kaye B., Wicks S.R., Lewis D., Weatherley A.J. In a study using mouse models of pancreatic cancer, the researchers found that in fact, PD-L1 is not highly expressed on pancreatic cancer cells. Guzzo C.A., Furtek C.I., Porras A.G., Chen C., Tipping R., Clineschmidt C.M., Sciberras D.G., Hsieh J.Y., Lasseter K.C. Formulated as a lotion, ivermectin is safe enough to be administered as an over-the-counter treatment for head lice in kids. Deng F., Xu Q., Long J., Xie H. Suppressing ROSTFE3dependent autophagy enhances ivermectininduced apoptosis in human melanoma cells. Mechanisms of IVM-induced mitochondria-mediated apoptosis. The discoverers of IVM, Japanese scientist Satoshi mura and Irish scientist William C. Campbell, won the Nobel Prize in Physiology or Medicine in 2015 [7,8]. IVM is a PAK1 inhibitor in a variety of tumors, and it has good safety compared to that of other PAK1 inhibitors such as IPA-3. Li X., Lewis M.T., Huang J., Gutierrez C., Osborne C.K., Wu M.F., Hilsenbeck S.G., Pavlick A., Zhang X., Chamness G.C., Wong H., Rosen J., Chang J.C. Intrinsic resistance of tumorigenic breast cancer cells to chemotherapy. PRR can identify pathogen-associated molecular patterns (PAMPs) that are structurally stable and evolutionarily conserved on the surface of pathogenic microorganisms and damage-associated molecular patterns (DAMPs) produced by damaged cells [84,85]. Nappi's experiment also proved that IVM combined with erlotinib to achieved a synergistic killing effect by regulating EGFR activity and in HCC827 lung cancer cells [50]. Liu Y., Fang S., Sun Q., Liu B. Anthelmintic drug ivermectin inhibits angiogenesis, growth and survival of glioblastoma through inducing mitochondrial dysfunction and oxidative stress. The ePub format uses eBook readers, which have several "ease of reading" features Therefore, this review summarized the latest findings on the anticancer effect of IVM and discussed the mechanism of the inhibition of tumor proliferation and the way that IVM induces tumor programmed cell death to provide a theoretical basis for the use of IVM as a potential anticancer drug. Dominguez-Gomez G., Chavez-Blanco A., Medina-Franco J.L., Saldivar-Gonzalez F., Flores-Torrontegui Y., Juarez M., Diaz-Chavez J., Gonzalez-Fierro A., Duenas-Gonzalez A. Ivermectin as an inhibitor of cancer stemlike cells. This was related to the induction of mitochondrial dysfunction and oxidative stress. On the other hand, some autophagy activators can increase the sensitivity of tumors to radiotherapy and chemotherapy by inducing autophagy, and excessive activation of autophagy can also lead to tumor cell death [[78], [79], [80], [81]]. Giving ivermectin with balstilimab may increase the effect of balstilimab in shrinking tumors in patients with triple negative breast cancer. Therefore, continued study and testing of safe and effective combination drug therapies is essential to maximize the anticancer effects of IVM. When the external environment is suitable, CSCs will rapidly proliferate to reactivate the formation and growth of tumors. Foy B.D., Alout H., Seaman J.A., Rao S., Magalhaes T., Wade M., Parikh S., Soma D.D., Sagna A.B., Fournet F., Slater H.C., Bougma R., Drabo F., Diabate A., Coulidiaty A.G.V., Rouamba N., Dabire R.K. Efficacy and risk of harms of repeat ivermectin mass drug administrations for control of malaria (RIMDAMAL): a cluster-randomised trial. Ivermectin is a macrolide antiparasitic drug with a 16-membered ring that is widely used for the treatment of many parasitic diseases such as river blindness, elephantiasis and scabies. Last Updated on January 5, 2023 by Shaun Snapp. Last. DEAD-box RNA helicase DDX23 modulates glioma malignancy via elevating miR-21 biogenesis. This included: a laboratory study showing that the drug acted as a strong antiviral in a petri dish, a study in a French nursing home where the residents took ivermectin to treat a scabies . Guadalupe evaluated the effect of IVM on CSCs in the breast cancer cell line MDA-MB-231 [95]. Second, IVM seems to induce mixed cell death in tumor cells, which is also a controversial issue. In a previous article titled How Ivermectin Is Useful for Treating Cancer we covered the evidence for the benefits of Ivermectin for cancer. Kwon Y.J., Petrie K., Leibovitch B.A., Zeng L., Mezei M., Howell L., Gil V., Christova R., Bansal N., Yang S., Sharma R., Ariztia E.V., Frankum J., Brough R., Sbirkov Y., Ashworth A., Lord C.J., Zelent A., Farias E., Zhou M.M., Waxman S. Selective Inhibition of SIN3 Corepressor with Avermectins as a Novel Therapeutic Strategy in Triple-Negative Breast Cancer. A review of 10 random clinical trials, with more than 1,000 participants, also didn . Finally, IVM changed the balance between apoptosis-related proteins by upregulating the protein Bax and downregulating anti-apoptotic protein Bcl-2, thereby activating caspase-9/-3 to induce apoptosis [48,53,63] (Fig. Although there is currently little evidences showing that IVM induces pyroptosis, it is important to investigate the role of IVM in inducing pyroptosis in other cancers in future studies and realize that IVM may induce different types of programmed cell death in different types of cancer. Executive Summary. WASHINGTON Ivermectin, a controversial drug used commonly as a horse dewormer as well as a treatment for parasitic infections in humans, could be capable of treating COVID-19 patients and potentially ending the pandemic, some scientists claim.The team of researchers, including three U.S. government senior scientists, are calling for governments around the world to start treating . We are experimenting with display styles that make it easier to read articles in PMC. PAK1 cross regulate multiple signal pathways. MDR of tumor cells is the main cause of relapses and deaths after chemotherapy [97]. We believe that IVM can be further developed and introduced clinically as part of new cancer treatments in the near future. Autophagy is a lysosomal-dependent form of programmed cell death. ATP binding transport family-mediated drug efflux and overexpression of P-glycoprotein (P-gp) are widely considered to be the main causes of tumor MDR [[98], [99], [100]]. Nambaras study showed that IVM could significantly inhibit the proliferation of gastric cancer cells in vivo and in vitro and that the inhibitory effect of IVM depended on the expression of Yes-associated protein 1(YAP1)[39]. (3) It has become increasingly clear that IVM can induce a mixed cell death mode involving apoptosis, autophagy and pyroptosis depending on the cell conditions and cancer type. Ivermectin is proven to treat a variety of different cancers.
