Abstract
This survey was conducted to fabrication of PLGA-based nanosystems modified with PEG, chitosan and folic acid to delivery colchicine to cancer cells and to investigate its antioxidant and pro-apoptotic effects. The dual emulsion-evaporation solvent method was used for loading of colchicine on PEGylated PLGA nanoparticles (COL-PP-NPs) and after surface modification with chitosan and folic acid (COL-PPCF-NPs), the nanoparticles were characterized by DLS, SEM and FTIR methods. The HPLC procedure was used to assess the amount of FA binding and COL loading. Antioxidant capacity (ABTS and DPPH free radical scavenging) and toxicity (MTT) of COL-PPCF-NPs were evaluated and then cell inhibition mechanism was assessed by AO/PI staining, flow cytometry and qPCR assay. COL-PPCF-NPs with a size of 250 nm were synthesized in a stable (zeta potential: +34 mV) and mono-dispersed (PDI: 0.32) manner. FA binding and COL loading were reported to be 55% and 89.5%, respectively. COL-PPCF-NPs showed antioxidant effects by inhibiting the free radicals ABTS (108.07 µg/ml) and DPPH (361.61 µg/ml). The selective toxicity of COL-PPCF-NPs against HT-29 cancer cells (118.5 µg/ml) compared to HFF cells was confirmed by MTT data. Increased apoptotic cells (red color) in AO/PI staining, cell arrest in phase SubG1 and G2-M, and altered expression of apoptosis genes confirmed the occurrence of apoptosis in HT-29 treated cells. The use of PPCF-NPs system for delivery of COL can lead to selective toxicity against cancer cells and induction of apoptosis in these cells by folate-mediated binding mechanism at folate receptor positive HT-29 cancer cells.

Targeted Nano-Drug Delivery of Colchicine against Colon Cancer Cells by Means of Mesoporous Silica Nanoparticles. Cancers (Basel) 2020; 12:E144. [PMID: 31936103 PMCID: PMC7017376 DOI: 10.3390/cancers12010144] [Citation(s) in RCA: 43] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Revised: 12/25/2019] [Accepted: 01/03/2020] [Indexed: 12/19/2022] Open
Abstract
Antimitotics are important anticancer agents and include the natural alkaloid prodrug colchicine (COL). However, a major challenge of using COL as an anticancer drug is its cytotoxicity. We developed a novel drug delivery system (DDS) for COL using mesoporous silica nanoparticles (MSNs). The MSNs were functionalized with phosphonate groups, loaded with COL, and coated with folic acid chitosan-glycine complex. The resulting nanoformulation, called MSNsPCOL/CG-FA, was tested for action against cancer and normal cell lines. The anticancer effect was highly enhanced for MSNsPCOL/CG-FA compared to COL. In the case of HCT116 cells, 100% inhibition was achieved. The efficiency of MSNsPCOL/CG-FA ranked in this order: HCT116 (colon cancer) > HepG2 (liver cancer) > PC3 (prostate cancer). MSNsPCOL/CG-FA exhibited low cytotoxicity (4%) compared to COL (~60%) in BJ1 normal cells. The mechanism of action was studied in detail for HCT116 cells and found to be primarily intrinsic apoptosis caused by an enhanced antimitotic effect. Furthermore, a contribution of genetic regulation (metastasis-associated lung adenocarcinoma transcript 1 (MALAT 1), and microRNA (mir-205)) and immunotherapy effects (angiopoietin-2 (Ang-2 protein) and programmed cell death protein 1 (PD-1) was found. Therefore, this study shows enhanced anticancer effects and reduced cytotoxicity of COL with targeted delivery compared to free COL and is a novel method of developing cancer immunotherapy using a low-cost small-molecule natural prodrug.

Abstract
Crassolide, a monocyclic diterpene isolated and purified from the soft coral Lobophytum crassum, inhibited the cell cleavage of sea urchin eggs without affecting fertilization. The effect was observed with concentrations above 2 x 10(-5)m in egg suspensions. Addition of crassolide between 5 and 40 min post-fertilization totally blocked the first cleavage, which in the control occurs 1 hr after fertilization. When added between 50 and 60 min post-fertilization, crassolide produced polynucleated cells in embryos. Crassolide did not affect the egg permeability to Na(+) and Ca(2+), but caused an increase of 0.2 units in the intracellular pH of fertilized eggs coupled with a proton efflux. Crassolide, which does not affect Ca(2+) influx or permeability at the level of storage in reticular vesicles, could be used as a negative control when analysing calcium changes in short-term toxicological studies. The relationship between the pH increase and the cell cleavage needs further investigation.

Abstract
Researchers in a wide variety of unrelated areas studying functions of different proteins are unexpectedly finding that their proteins of interest are actually mitochondrial proteins, although functions would appear to be extramitochondrial. We review the leading current examples of mitochondrial macromolecules indicated to be also present outside of mitochondria that apparently exit from mitochondria to arrive at their destinations. Mitochondrial chaperones, which have been implicated in growth and development, autoimmune diseases, cell mortality, antigen presentation, apoptosis, and resistance to antimitotic drugs, provide some of the best studied examples pointing to roles for mitochondria and mitochondrial proteins in diverse cellular phenomena. To explain the observations, we propose that specific export mechanisms exist by which certain proteins exit mitochondria, allowing these proteins to have additional functions at specific extramitochondrial sites. Several possible mechanisms by which mitochondrial proteins could be exported are discussed. Gram-negative proteobacteria, from which mitochondria evolved, contain a number of different mechanisms for protein export. It is likely that mitochondria either retained or evolved export mechanisms for certain specific proteins.

Abstract
This is a report of colchicine poisoning in a 24-year-old woman. She developed multiple organ failure and bone marrow suppression after the suicidal ingestion of 50 (1 mg) colchicine tablets. The pancytopenia responded to granulocyte colony-stimulating factor 300 micrograms on days 4, 5, 6, and 8. Although anticolchicine monoclonal antibody administration is the only specific therapy described, intensive supportive care including granulocyte colony-stimulating factor administration can facilitate recovery from severe colchicine intoxication.

Abstract
A large number of antimicrotubule agents are known that bind to tubulin in vitro and disrupt microtubule assembly in vitro and in vivo. Many of these agents bind to the same site on the tubulin molecule, as does colchicine. Of these, the natural products podophyllotoxin, steganacin and combretastatin are the subjects of this review. For each of these, the chemistry and biochemistry are described. Particular attention is given to stereochemical considerations. Biosynthetic pathways for podophyllotoxin and congeners are surveyed. The binding to tubulin and the effects on microtubule assembly and disassembly are described and compared. In addition, structural features important to binding are examined using available analogs. Several features significant for tubulin interaction are common to these compounds and to colchicine. These are described and the implications for tubulin structure are discussed. The manifold results of applying these agents to biological systems are reviewed. These actions include effects that are clearly microtubule mediated and others in which the microtubule role is less obvious. Activity of some of these compounds due to inhibition of DNA topoisomerase is discussed. The range of species in which these compounds occur is examined and in the case of podophyllotoxin is found to be quite broad. In addition, the range of species that are sensitive to the effects of these compounds is discussed.

Abstract
Two proteins, P1 and P2, which are specifically altered in mammalian cell mutants resistant to antimitotic drugs, have been identified as the homologs of two members of the class of proteins known as molecular chaperones. P1 is localized in mitochondria and P2-related proteins are involved in the translocation of proteins to mitochondria. To account for these and a number of other observations, a new model for in vivo microtubule assembly is proposed.
