Abstract
Two variants of Ca2+-regulated photoprotein obelin, extended from the N-terminus with small tumor markers - melanoma inhibitory activity protein (MIA) and survivin, one of the protein inhibitors of apoptosis, were designed, obtained and studied. Both domains in the obtained hybrid proteins exhibit the properties of the initial molecules: the main features of Ca2+-triggered bioluminescence are close to those of obelin, and the tumor markers' domains are recognized and bound by the corresponding antibodies. The obtained hybrids compete with the corresponding tumor markers for binding with antibodies, immobilized on the surface and their use has been shown to be promising as bioluminescent labels in a one-stage solid-phase competitive immunoassay.

Cancers (Basel) 2019; 11:cancers11121982. [PMID: 31835393 PMCID: PMC6966600 DOI: 10.3390/cancers11121982] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 12/02/2019] [Accepted: 12/03/2019] [Indexed: 11/29/2022] Open
Abstract
The effectiveness of existing anti-cancer therapies is based mainly on the stimulation of apoptosis of cancer cells. Most of the existing therapies are somewhat toxic to normal cells. Therefore, the quest for nontoxic, cancer-specific therapies remains. We have demonstrated the ability of liposomes containing anacardic acid, mitoxantrone and ammonium ascorbate to induce the mitochondrial pathway of apoptosis via reactive oxygen species (ROS) production by the killing of cancer cells in monolayer culture and shown its specificity towards melanoma cells. Liposomes were prepared by a lipid hydration, freeze-and-thaw (FAT) procedure and extrusion through polycarbonate filters, a remote loading method was used for dug encapsulation. Following characterization, hemolytic activity, cytotoxicity and apoptosis inducing effects of loaded nanoparticles were investigated. To identify the anticancer activity mechanism of these liposomes, ROS level and caspase 9 activity were measured by fluorescence and by chemiluminescence respectively. We have demonstrated that the developed liposomal formulations produced a high ROS level, enhanced apoptosis and cell death in melanoma cells, but not in normal cells. The proposed mechanism of the cytotoxic action of these liposomes involved specific generation of free radicals by the iron ions mechanism.

Abstract
Metastatic Melanoma (MM) is a deadly form of skin cancer and many photodynamic therapy (PDT) studies have noted limitations in relation to effective photosensitizer (PS) drug uptake in tumors. The focus of this study was to develop a PS multicomponent nanoparticle drug conjugate carrier system which specifically targets MM cells via biomarkers to actively enhance PS delivery and so improve MM PDT. An antibody-metallated phthalocyanine-polyethylene glycol-gold nanoparticle drug conjugate, was successfully synthesized and characterized. PS active drug targeting PDT experiments at 673 nm were conducted within in vitro cultured MM. Results noted that this drug conjugate enhanced the PDT treatment of MM, through improved subcellular localization of the PS, as well as noted significantly improved cytotoxic and late apoptotic cellular death in cells. The results from this study demonstrate that through the bio-active antibody PS drug targeting of MM, the efficacy of PDT treatment for this cancer can be enhanced.

Abstract
We continue analysis of the phenotype of human melanoma cell Mel Ibr subclone obtained previously by treatment of the parental cell line by chicken embryo extract. The present study is focused on detection of markers of epithelial-mesenchymal transition that determine enhanced metastatic and invasive potential of malignant tumors of various locations. Analysis of the expression of E-cadherin and vimentin genes in the subclone and parental cells detected activation of epithelial-mesenchymal transition in the subclone. Immunological markers CD90, CD271, and CD95 were present in the parental population, but were not detected on the subclone cells. In contrast to the parental line, cells of the analyzed subclone retain viability in serum-free medium and formed vessel-like structures characteristic of vasculogenic mimicry.

Abstract
The conventional chemotherapeutic treatment of malignant melanoma still remains poorly efficient in most cases. Thus the use of specific features of these tumors for development of new therapeutic modalities is highly needed. Melanocortin 1 receptor (MC1R) overexpression on the cell surface of the vast majority of human melanomas, making MC1R a valuable marker of these tumors, is one of these features. Naturally, MC1R plays a key role in skin protection against damaging ultraviolet radiation by regulating eumelanin production. MC1R activation is involved in regulation of melanocyte cell division. This article reviews the peculiarities of regulation and expression of MC1R, melanocytes, and melanoma cells, along with the possible connection of MC1R with signaling pathways regulating proliferation of tumor cells. MC1R is a cell surface endocytic receptor, thus considered perspective for diagnostics and targeted drug delivery. A number of new therapeutic approaches that utilize MC1R, including endoradiotherapy with Auger electron and α- and β-particle emitters, photodynamic therapy, and gene therapy are now being developed.
