Diana A., Carlino F., Franzese E., Oikonomidou O., Criscitiello C., De Vita F., Ciardiello F., Orditura M. Early Triple Negative Breast Cancer: Conventional Treatment and Emerging Therapeutic Landscapes. Ivermectin induces apoptosis and autophagy is mutually regulated. Summary of IVM promotes programmed cell death. Emerging Role of Circulating Tumor Cells in Gastric Cancer. Overall, we speculate that IVM can regulate the Akt/mTOR, MAPK and other pathways that are essential for tumor cell proliferation by inhibiting PAK1 expression, which plays an anticancer role in most cancers. In a study that screened Wnt pathway inhibitors, IVM inhibited the proliferation of multiple cancers, including the colorectal cancer cell lines CC14, CC36, DLD1, and Ls174 T, and promoted apoptosis by blocking the Wnt pathway [41]. If you are pregnant, nursing, taking medication, or have a medical . Lim S.M., Syn N.L., Cho B.C., Soo R.A. Acquired resistance to EGFR targeted therapy in non-small cell lung cancer: Mechanisms and therapeutic strategies. Glioma stem cells promote radioresistance by preferential activation of the DNA damage response. This study to examine ivermectin, as well as a few other current medications to gauge their effectiveness against COVID-19, goes by the name of ACTIV-6. Animal studies with rats given 3 times the maximum recommended human dose of 200 mcg/kg did not show any . In addition, morphological changed caused by apoptosis, including chromatin condensation, nuclear fragmentation, DNA fragmentation and apoptotic body formation were observed. Bao S., Wu Q., McLendon R.E., Hao Y., Shi Q., Hjelmeland A.B., Dewhirst M.W., Bigner D.D., Rich J.N. 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]. A clinical trial of 476 patients found ivermectin didn't improve the recovery time in patients who had COVID-19. Ivermectin is used to treat river blindness (onchocerciasis), intestinal infection from threadworms (strongyloidiasis), and other kinds of worm infections. Guadalupe evaluated the effect of IVM on CSCs in the breast cancer cell line MDA-MB-231 [95]. This suggests that ivermectin may be an anticancer drug with great potential. The majority of cervical cancers are caused by human papillomavirus (HPV) infection [54,55]. Views. The authors speculated that IVM may mediate the occurrence of pyroptosis via the P2 4/P2 7/NLRP3 pathway (Fig. Gastric cancer is one of the most common malignant tumors worldwide. Mastrangelo E., Pezzullo M., De Burghgraeve T., Kaptein S., Pastorino B., Dallmeier K., de Lamballerie X., Neyts J., Hanson A.M., Frick D.N., Bolognesi M., Milani M. Ivermectin is a potent inhibitor of flavivirus replication specifically targeting NS3 helicase activity: new prospects for an old drug. We have already mentioned that IVM plays an anticancer role in various tumors by regulating pathways closely related to cancer development. The secondary objectives of the study include evaluating the following efficacy outcomes: objective response rate (ORR), progression free survival (PFS), overall survival (OS), duration of response (DOR . Ivermectin is approved for human . But the BBC can reveal there are serious errors in a . 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. Ivermectin, an antiparasitic drug, has been shown to possess anti-inflammation, anti-virus, and antitumor properties. ). Column: Definitive study shows ivermectin is utterly useless against COVID-19. 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. 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 . For some older drugs that are widely used for their original indications and have clinical data and safety information, drug repositioning allows them to be developed via a cheaper and faster cycle and to be used more effectively in clinical use clinically [29]. Kobayashi Y., Banno K., Kunitomi H., Tominaga E., Aoki D. Current state and outlook for drug repositioning anticipated in the field of ovarian cancer. . Interestingly, IVM and paclitaxel have a synergistic effect on ovarian cancer, and combined treatment in in vivo experiments almost completely inhibited tumor growth. Summary of the anticancer mechanism of IVM. On the other hand, ivermectin promotes programmed cancer cell death, including apoptosis, autophagy and pyroptosis. This proves that IVM mainly exerts an antitumor effect through the autophagy pathway. (4) IVM can enhance the sensitivity of chemotherapeutic drugs and reduce the production of resistance. Recent studies have found that IVM could be used as an inhibitor of HSP27 phosphorylation to enhance the activity of anti-EGFR drugs in EGFR/HER2- driven tumors. Kumar R., Li D.Q. 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. Jiang L., Wang P., Sun Y.J., Wu Y.J. Giving ivermectin with balstilimab may increase the effect of balstilimab in shrinking tumors in patients with triple negative breast cancer. Moreover, IVM was also found to have a good inhibitory effect on the prostate cancer cell line DU145 [51]. Nambara S., Masuda T., Nishio M., Kuramitsu S., Tobo T., Ogawa Y., Hu Q., Iguchi T., Kuroda Y., Ito S., Eguchi H., Sugimachi K., Saeki H., Oki E., Maehara Y., Suzuki A., Mimori K. Antitumor effects of the antiparasitic agent ivermectin via inhibition of Yes-associated protein 1 expression in gastric cancer. Ashour D.S. Prostate cancer is a malignant tumor derived from prostate epithelial cells, and its morbidity is second only to that of lung cancer among men in Western countries [49]. It has been widely used in humans for many years, and its various pharmacological properties, including long- and short-term toxicological effects and drug metabolism characteristics are very clear. Juarez M., Schcolnik-Cabrera A., Duenas-Gonzalez A. 109,110]. It included data from Surgisphere, a company that also provided inaccurate patient data . 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]]. Geyer J., Gavrilova O., Petzinger E. Brain penetration of ivermectin and selamectin in mdr1a,b P-glycoprotein- and bcrp- deficient knockout mice. Retweets. 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. In a study published in the journal Oncotarget on July 6, Gregory Riggins, M.D., Ph.D., professor of neurosurgery and oncology at the Johns Hopkins University School of Medicine, and his team used two different mouse models to determine that the anti-parasitic drug mebendazole could slow or stop the growth and spread of both early and late-stage pancreatic cancer. 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. It is characterized by double-layered or multilayered vacuolar structures containing cytoplasmic components, which are known as autophagosomes [77]. Diao H., Cheng N., Zhao Y., Xu H., Dong H., Thamm D.H., Zhang D., Lin D. Ivermectin inhibits canine mammary tumor growth by regulating cell cycle progression and WNT signaling. Finally, activated PARP and caspase-3 trigger apoptosis. After IVM intervention in breast cancer, the expression of PAK1 was also significantly inhibited, and the use of siRNA to downregulate the expression of PAK1 in tumor cells significantly reduced the anticancer activity of IVM. Mechanisms of IVM-induced PAK1/Akt/mTOR-mediated autophagy. Received 2020 Jun 5; Revised 2020 Sep 11; Accepted 2020 Sep 11. Several studies have confirmed that IVM could reverse drug resistance by inhibiting P-gp and MDR-associated proteins [[101], [102], [103]]. Markowska A., Kaysiewicz J., Markowska J., Huczynski A. Doxycycline, salinomycin, monensin and ivermectin repositioned as cancer drugs. Autophagy is a lysosomal-dependent form of programmed cell death. Liu X., Zhang Z., Ruan J., Pan Y., Magupalli V.G., Wu H., Lieberman J. Inflammasome-activated gasdermin D causes pyroptosis by forming membrane pores. The study was conducted on 18 rectal cancer patients at Memorial Sloan Kettering Cancer Center in Manhattan and had a 100 percent success rate, according to a paper published Sunday in the New . Despite the large number of related studies, there are still some key issues that have not been resolved. 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. All of the above findings indicate the potential of IVM as an autophagy activator to induce autophagy-dependent death in tumor cells. The experimental results showed that IVM would preferentially targeted and inhibited CSCs-rich cell populations compared with other cell populations in MDA-MB-231 cells. Cancer stem cells and radiotherapy: new insights into tumor radioresistance. IVM can promote ROS release in cancer cells by P2 4/P2 7 receptors. In a study that screened drugs for the treatment of nasopharyngeal cancer, IVM significantly inhibited the development of nasopharyngeal carcinoma in nude mice at doses that were not toxic to normal thymocytes [69]. Ravegnini G., Sammarini G., Nannini M., Pantaleo M.A., Biasco G., Hrelia P., Angelini S. Gastrointestinal stromal tumors (GIST): Facing cell death between autophagy and apoptosis. In this comprehensive systematic review, antiviral effects of ivermectin are summarized including in vitro and in . I take small doses of 6-12 mg regularly (3-4 x/week) after reading about it at NIH.gov, which someone else has now posted. The mechanism involved the inhibition by IVM of the Akt/mTOR pathway to induce autophagy and p-21-activated kinase 1(PAK1)was the target of IVM for breast cancer [32]. We formerly reported that the combination of dichloroacetate, omeprazole, and tamoxifen blocked cancer progression by reducing lactic acid production and inducing superoxide production. MDR of tumor cells is the main cause of relapses and deaths after chemotherapy [97]. Colorectal cancer (CRC) is the third most common cancer worldwide and still lacks effective therapy. The clinical trials described in this table are RCTs that had the greatest impact on the Panel's recommendation. p21-activated kinases in cancer. The combination of drugs can effectively increase efficacy, reduce toxicity or delay drug resistance.

Nishio found that IVM could significantly inhibit the proliferation of H1299 lung cancer cells by inhibiting YAP1 activity [43]. P2X4 receptor exacerbates ischemic AKI and induces renal proximal tubular NLRP3 inflammasome signaling. The Prime Minister of Malaysia proclaimed a state of Emergency Ordinance on the 12th January 2021. On the other hand, ivermectin promotes programmed cancer cell death, including apoptosis, autophagy and pyroptosis. Caly L., Druce J.D., Catton M.G., Jans D.A., Wagstaff K.M. 5. "It is a far cry from an in vitro lab replication to helping humans," said Dr. Nasia Safdar, medical director of infection prevention at the University of Wisconsin-Madison Hospital. A new study evaluated the effect of ivermectin on time to recovery from coronavirus disease 2019 (COVID-19) in patients with mild to moderate disease. The COVID-19 resource centre is hosted on Elsevier Connect, the company's public news and information website. The incidence of breast cancer has increased each year, and it has become one of the female malignant tumors with the highest incidence in globally. Over 25 Years of Clinical Experience With Ivermectin: An Overview of Safety for an Increasing Number of Indications. Moreover, the expression of the homeobox protein NANOG, octamer-binding protein 4 (OCT-4) and SRY-box 2 (SOX-2), which are closely related to the self-renewal and differentiation ability of stem cells in CSCs, were also significantly inhibited by IVM.
