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. Melotti A., Mas C., Kuciak M., Lorente-Trigos A., Borges I., Ruiz i Altaba A. Therefore, IVM should be used in combination with other drugs to achieve the best effect, while the specific medication plan used to combine IVM with other drugs remains to be explored. 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. Antibiotic ivermectin preferentially targets renal cancer through inducing mitochondrial dysfunction and oxidative damage. This indicated that IVM may be a potential RNA helicase inhibitor and a new agent for of tumor treatment. Not only does IVM not overlap with other therapies in term of its mechanism of action, but the fact that of IVM has multiple targets suggests that it is not easy to produce IVM resistance. In addition, researchers also used the Akt activator CA-Akt to prove that IVM mainly induces autophagy by inhibiting the phosphorylation of Akt and mTOR (Fig. ). Therefore, we believe that the anticancer effect of IVM is not limited to cytotoxicity, but also involves the regulation of the tumor microenvironment. The DDX23 helicase activity affects the expression of miR-12 [66]. As the cost of the research and development of new anticancer drugs continues to increase, drug repositioning has become increasingly important. Ivermectin is an anthelmintic. Ivermectin is used to treat river blindness (onchocerciasis), intestinal infection from threadworms (strongyloidiasis), and other kinds of worm infections. Its morbidity has increased by an average of 2% annually worldwide and the clinical treatment effect is not satisfactory [[45], [46], [47]]. Tumor microenvironment: Challenges and opportunities in targeting metastasis of triple negative breast cancer. "The drug induces a response in certain patients, and several trial patients stayed on selinexor for more than 12 months, including one for over 42 months," adds Dr. Lassman, who also is associate director for clinical trials at the Herbert Irving Comprehensive Cancer Center. Targeting Heat Shock Protein 27 in Cancer: A Druggable Target for Cancer Treatment? Caly L., Druce J.D., Catton M.G., Jans D.A., Wagstaff K.M. Han S.J., Lovaszi M., Kim M., DAgati V., Hasko G., Lee H.T. Top medical journals have rejected a paper about the study, and its main author, Flavio Cadegiani, an endocrinologist at the biotech company Applied Biology, has previously touted unproven COVID-19 medications, such as ivermectin, azithromycin, and antiworm compounds. Yin J., Park G., Lee J.E., Choi E.Y., Park J.Y., Kim T.H., Park N., Jin X., Jung J.E., Shin D., Hong J.H., Kim H., Yoo H., Lee S.H., Kim Y.J., Park J.B., Kim J.H. The study was published January 10, 2022 in Clinical Cancer Research. Mechanisms of IVM-induced P2 4/P2 7/NLRP3-mediated pyroptosis. 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. 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 . But the question of which cancers Ivermectin has been proven effective is a constant source of questions. As reported earlier, it may have anti-tumor, anti metastasis properties against some cancers. Therefore, the development of new drugs that can overcome resistance, improve anticancer activity, and reduce side effects is an urgent problem to be solved in chemotherapy. However, whether ivermectin affects CRC is still unclear. (4) IVM can enhance the sensitivity of chemotherapeutic drugs and reduce the production of resistance. Ashour D.S. Interestingly, IVM could also show activity against BRAF wild-type melanoma cells, and its combination with dapafinib could significantly increase antitumor activity. (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. In gliomas, miR-21 can regulate the Ras/MAPK signaling pathway and enhance its effects on proliferation and invasion [65]. In addition, IVM could reduce the metastasis of lung cancer cells by inhibiting EMT. 109,110]. All of the above findings indicate the potential of IVM as an autophagy activator to induce autophagy-dependent death in tumor cells. Targeting PAK1 is a novel and promising method for cancer treatment, and the development of PAK1 inhibitors has attracted widespread attention [111]. In addition, characteristic pyroptosis phenomena such as cell swelling and rupturing were observed. Didier A., Loor F. The abamectin derivative ivermectin is a potent p-glycoprotein inhibitor. It included data from Surgisphere, a company that also provided inaccurate patient data . Autophagy-Independent Functions of the Autophagy Machinery. Interestingly, IVM could inhibit the expression of PAK1 protein but did not affect the expression of PAK1 mRNA [32].The proteasome inhibitor MG132 reversed the suppressive effect of IVM, which indicated that IVM mainly degraded PAK1 via the proteasome ubiquitination pathway. PAK1 can induce MEK1/2 and ERK1/2 activation by RAF and increase PI3K/Akt signaling by PDK1. In vivo loss-of-function screens identify KPNB1 as a new druggable oncogene in epithelial ovarian cancer. Finally, activated PARP and caspase-3 trigger apoptosis. Franken M.G., Leeneman B., Gheorghe M., Uyl-de Groot C.A., Haanen J., van Baal P.H.M. We formerly reported that the combination of dichloroacetate, omeprazole, and tamoxifen blocked cancer progression by reducing lactic acid production and inducing superoxide production. 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. Marino G., Niso-Santano M., Baehrecke E.H., Kroemer G. Self-consumption: the interplay of autophagy and apoptosis. Over 25 Years of Clinical Experience With Ivermectin: An Overview of Safety for an Increasing Number of Indications. Studies suggesting ivermectin is an effective Covid treatment relied on evidence 'that has substantially evaporated under close scrutiny', fresh research shows However, after using the autophagy inhibitors chloroquine and wortmannin or knocking down Bclin1 and Atg5 by siRNA to inhibit autophagy, the anticancer activity of IVM significantly decreased. 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. Kane N.S., Hirschberg B., Qian S., Hunt D., Thomas B., Brochu R., Ludmerer S.W., Zheng Y., Smith M., Arena J.P., Cohen C.J., Schmatz D., Warmke J., Cully D.F. 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]. What this study does and does not show. Old wine in new bottles: Drug repurposing in oncology. 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. Second, IVM seems to induce mixed cell death in tumor cells, which is also a controversial issue. Chen Y.P., Chan A.T.C., Le Q.T., Blanchard P., Sun Y., Ma J. Nasopharyngeal carcinoma. The aim of the present study was to demonstrate that ivermectin preferentially inhibited cancer stemlike cells (CSC) in breast cancer cells and downregulated the expression of 'stemness' genes.

Relationship between Oxidative Stress and Physical Activity in Women with Squamous Intraepithelial Lesions in a Cervical Cancer Control Program in the Brazilian Amazon. However, NAC reversed the effect of IVM, which indicated that IVM increased TFE3-dependent autophagy through the ROS signaling pathway. Introduction. the display of certain parts of an article in other eReaders. We have already mentioned that IVM plays an anticancer role in various tumors by regulating pathways closely related to cancer development.

The river blindness drug Ivermectin and related macrocyclic lactones inhibit WNT-TCF pathway responses in human cancer. Ivermectin induces apoptosis and autophagy is mutually regulated. 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].

A review of 10 random clinical trials, with more than 1,000 participants, also didn . This suggests that ivermectin may be an anticancer drug with great potential. Harbeck N., Penault-Llorca F., Cortes J., Gnant M., Houssami N., Poortmans P., Ruddy K., Tsang J., Cardoso F. Breast cancer. Additionally, it has been confirmed that PAK1 is the key target of IVM that mediates its anti-melanoma activity, and IVM can also significantly reduce the lung metastasis of melanoma in animal experiments. PAKs in Human Cancer Progression: From Inception to Cancer Therapeutic to Future Oncobiology. This proves that IVM mainly exerts an antitumor effect through the autophagy pathway. 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. 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]]. The authors speculated that IVM may mediate the occurrence of pyroptosis via the P2 4/P2 7/NLRP3 pathway (Fig. Abstract. 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. A systematic literature review and network meta-analysis of effectiveness and safety outcomes in advanced melanoma. Written by Carolyn Crist. Ivermectin, an antiparasitic drug, has been shown to possess anti-inflammation, anti-virus, and antitumor properties. Colorectal cancer (CRC) is the third most common cancer worldwide and still lacks effective therapy. The article, "Ivermectin: a systematic review from antiviral effects to COVID-19 complementary regimen," is a review of various studies on the antiviral effects of ivermectin. The chemical structures of ivermectin and other avermectin family compounds in this review. 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]. Surprisingly, gemcitabine-resistant KKU214 cells showed high sensitivity to IVM, which suggested that IVM shows potential for the treatment of tumors that are resistant to conventional chemotherapy drugs. A drug screening study of TNBC showed that IVM could be used as a SIN3-interaction domain (SID) mimic to selectively block the interaction between SID and paired a-helix2. However, in special circumstances, autophagy may also help to induce apoptosis or necrosis [83]. We found that the anticancer . EverythingIsFine . Nagata S. Apoptosis and Clearance of Apoptotic Cells. Several studies have confirmed that IVM could reverse drug resistance by inhibiting P-gp and MDR-associated proteins [[101], [102], [103]]. 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].

The FDA first issued a warning in April 2020 that ivermectin intended for use in animals should not be used to treat COVID-19 . In Nappi's experiment, it was found that IVM could enhance the drug activity of the anti-androgen drug enzalutamide in the prostate cancer cell line LNCaP and reverse the resistance of the prostate cancer cell line PC3 to docetaxel [50]. These results showed that IVM had the potential to resist tumor angiogenesis and tumor metastasis. The Panel reviewed other clinical studies of IVM for the treatment of COVID-19.
