Abstract
PROPOSE Human epidermal growth factor receptor 2 (HER2) is overexpressed on the surface of some kinds of cancer cells including breast cancer. In this study, we designed and produced a novel immunotoxin consisting anti-HER2 single-chain Fv (scFv) from pertuzumab and a modified form of Pseudomonas exotoxin (PE35KDEL). METHODS The three-dimensional (3D) structure of the fusion protein (anti-HER IT) was predicted by MODELLER 9.23 and its interaction with HER2 receptor was assessed using HADDOCK web server. Anti-HER2 IT, anti-HER2 scFv, and PE35KDEL proteins were expressed by Escherichia coli BL21 (DE3). After purification of the proteins using Ni2+ affinity chromatography and refolding through dialysis, the cytotoxicity of proteins against breast cancer cell lines was examined by MTT assay. RESULTS In-silico studies showed that (EAAAK)2 linker can efficiently prevent the formation of salt bridges between two functional domains and the constructed fusion protein has a high affinity to HER2 receptor. The optimum condition of anti-HER2 IT expression was 25 °C and 1 mM IPTG. The protein was successfully purified and refolded by dialysis with a final yield of 45.7 mg per 1 L of bacterial culture. The cytotoxicity results showed that anti-HER2 IT was much more toxic on HER2-overexpressing cells, BT-474 (IC50 ~ 95 nM) compared with HER2-negative cells, MDA-MB-23 (IC50 ˃ 200 nM). CONCLUSION This novel immunotoxin has the potential to be applied as a therapeutic candidate for HER2-targeted cancer therapy. However further in vitro and in vivo evaluations are still required to confirm the efficacy and safety of this protein.

Abstract
Understanding the molecular mechanisms of cancer biology introduces targeted therapy as a complementary method along with other conventional therapies. Recombinant immunotoxins are tumor specific antibodies that their recognizing fragment is utilized for delivering modified toxins into tumor cells. These molecules have been considered as a targeted strategy in the treatment of human cancers. HER2 tumor biomarker is a transmembrane tyrosine kinase receptor that can be used for targeted therapies in the forms of anti-HER2 monoclonal antibodies, antibody-drug conjugates and immunotoxins. There have been many studies on HER2-based immunotoxins in recent years, however, little progress has been made in the clinical field which demanded more improvements. Here, we summarized the HER2 signaling and it's targeting using immunotherapeutic agents in human cancers. Then, we specifically reviewed anti-HER2 immunotoxins, and their strengths and drawbacks to highlight their promising clinical impact.

Abstract
Cancer cells frequently overexpress specific surface receptors providing tumor growth and survival which can be used for precise therapy. Targeting cancer cell receptors with protein toxins is an attractive approach widely used in contemporary experimental oncology and preclinical studies. Methods of targeted delivery of toxins to cancer cells, different drug carriers based on nanosized materials (liposomes, nanoparticles, polymers), the most promising designed light-activated toxins, as well as mechanisms of the cytotoxic action of the main natural toxins used in modern experimental oncology, are discussed in this review. The prospects of the combined therapy of tumors based on multimodal nanostructures are also discussed.

Abstract
Immunotoxin targeted therapy is a promising way of cancer therapy that is made from a toxin attached to an antibody which target a specific protein presented on cancer cells. In this study, we introduce immunotoxins comprising of truncated pseudomonas exotoxin A (PEA) and diphtheria toxin (DT) conjugated to trastuzumab. The effectiveness of 20 and 30 μg/ml immunotoxins and trastuzumab were studied on SK-BR-3 and BT-474 HER2/neu positive breast cancer cell lines by a cell death assay test. The produced immunotoxins have the potential to reduce the therapeutic dose of the trastuzumab and in the same time achieve higher efficiency.

Abstract
BACKGROUND Ribosome-inactivating proteins (RIPs) are wildly found in multiple species of plants, bacteria and fungi. As a special family of protein toxins, RIPs can inhibit protein synthesis and induce cell death via inactivating ribosome in eukaryotic cells. Thus, RIPs have been applied for anti-tumor therapy in the past two decades. However, because of poor cell permeability, nonselective mode of action for tumor cells, poor pharmacokinetic profiles and immunogenicity, their clinical application has been severely constrained. As an effort to overcome these obstacles, tumor-specific monoclonal antibodies (mAb) have been conjugated to RIPs (forming so called "immunotoxins") specifically to increase their cytotoxicity and provide tumor targeting. Nevertheless, immunotoxins yet have not fully resolved all the issues and critical challenges still remain, such as immunogenicity and inability to penetrate into the deep site of tumor. OBJECTIVE To overcome the constrain of immunotoxins, the novel cell-penetrating peptide (CPP)- modified ATTEMPTS systems based on combination of CPP-mediated penetration and antibodymediated tumor targeting, with triggerable drug release function, were developed to achieve effective and safe delivery of protein toxin. RESULTS The CPP-modified ATTEMPTS systems showed effective protamine-triggered CPP-toxin release and thus enhanced CPP-mediated cellular uptake and cytotoxicity. It also showed antibodymediated in vivo tumor targeting and significantly increased in vivo tumor growth suppression with limited systematic toxicity. CONCLUSION The CPP-modified ATTEMPTS systems were developed and demonstrated as a proof-ofconcept for CPP-based protein toxin delivery with triggerable antibody targeting to improve the druggability of protein toxin drugs. The systems showed the potential application of protein toxin clinical translation in anticancer treatment.

Abstract
High immunogenicity and systemic toxicity are the main obstacles limiting the clinical use of the therapeutic agents based on Pseudomonas aeruginosa exotoxin A. In this work, we studied the immunogenicity, general toxicity and antitumor effect of the targeted toxin DARPin-LoPE composed of HER2-specific DARPin and a low immunogenic exotoxin A fragment lacking immunodominant human B lymphocyte epitopes. The targeted toxin has been shown to effectively inhibit the growth of HER2-positive human ovarian carcinoma xenografts, while exhibiting low non-specific toxicity and side effects, such as vascular leak syndrome and liver tissue degradation, as well as low immunogenicity, as was shown by specific antibody titer. This represents prospects for its use as an agent for targeted therapy of HER2-positive tumors.

Abstract
Malignant tumors are characterized by structural and molecular peculiarities providing a possibility to directionally deliver antitumor drugs with minimal impact on healthy tissues and reduced side effects. Newly formed blood vessels in malignant lesions exhibit chaotic growth, disordered structure, irregular shape and diameter, protrusions, and blind ends, resulting in immature vasculature; the newly formed lymphatic vessels also have aberrant structure. Structural features of the tumor vasculature determine relatively easy penetration of large molecules as well as nanometer-sized particles through a blood⁻tissue barrier and their accumulation in a tumor tissue. Also, malignant cells have altered molecular profile due to significant changes in tumor cell metabolism at every level from the genome to metabolome. Recently, the tumor interaction with cells of immune system becomes the focus of particular attention, that among others findings resulted in extensive study of cells with preferential tropism to tumor. In this review we summarize the information on the diversity of currently existing approaches to targeted drug delivery to tumor, including (i) passive targeting based on the specific features of tumor vasculature, (ii) active targeting which implies a specific binding of the antitumor agent with its molecular target, and (iii) cell-mediated tumor targeting.

Abstract
The concept of targeted therapy implies the development of bifunctional agents complementing the therapeutic module with a targeting one. A promising target for the delivery of imaging and/or toxic modules is the HER2 (ErbB2) receptor. Earlier, we have functionally characterized the targeted photosensitizers 4D5scFv-miniSOG and DARPin-miniSOG, causing the death of HER2-overexpressing cells when irradiated with blue light. However, the cytotoxicity of targeted toxins 4D5scFv-miniSOG and DARPin-miniSOG (both having functionally active targeted and cytotoxic modules in recombinant proteins) against human breast adenocarcinoma cells differs 5 times. The study of the dynamics of internalization of 4D5scFv-miniSOG and DARPin-miniSOG proteins in the complex with HER2 in this work showed that the rate of internalization contributes most significantly to the toxicity of these photosensitizers, because it determines the duration of the presence of the phototoxin in the lipid bilayer of the cell membrane, where its damaging effect is maximum.

Abstract
Immunotoxin 4D5scFv-PE40 is a recombinant protein that comprises 4D5scFv antibody as a targeting module and fragment of Pseudomonas exotoxin A as an effector (toxic) one. The immunotoxin has shown pronounced antitumor effect on cancer cells overexpressing HER2 receptor in vitro and on HER2-positive experimental tumors in vivo. We clarified the mechanism of 4D5scFv-PE40 activity that is of particular importance in the case of targeted therapeutic agent aimed at personalizing treatment of disease in relation to molecular genetic characteristics of each patient. After specific binding to HER2 on the cell surface and clathrin-mediated endocytosis the immunotoxin passes through retrograde trafficking route. During this route the immunotoxin molecule is supposed to undergo enzymatic processing that ends in separation of C-terminal and N-terminal fragments of the immunotoxin. Finally, C-terminal functionally active fragment of 4D5scFv-PE40 arrests protein synthesis in cytoplasm followed by cell death via apoptosis.

Abstract
DARPins fused with other proteins are promising non-immunoglobulin scaffolds for specific binding to target cells. In this study HER2-specific DARPin (DARPin_9-29) was used as a tumor-targeting moiety for the delivery of a cytotoxic agent - the fragment of Pseudomonas aeruginosa exotoxin A. It was determined that DARPin-PE40 possesses a considerable cytotoxic activity and induces apoptosis in HER2-positive cells. Cytotoxic effect of DARPin-PE40 strongly correlates with the HER2 expression level. The effect of intravenous administration of DARPin-PE40 was tested in the xenograft model of breast cancer. It was shown that treatment of animals with DARPin-PE40 caused strong and prolonged suppression of xenograft tumor growth.

Abstract
We have created novel HER2-overexpressing human ovarian adenocarcinoma cell line stably transfected with far-red fluorescent protein TurboFP635. Growth characteristics, adhesion capacity and morphology of the cells do not differ from that of parental cell line. The obtained cell line (SKOV-kat) was confirmed to have high level of expression of the tumor marker HER2 comparable to that of initial cell line SKOV-3. The SKOV-kat cell line is designed for further establishment of experimental fluorescent models of HER2-overexpressing human ovarian cancer that make it possible to optimize and reduce the cost of preclinical study of agents for treatment of this disease.
