Nanofiber dressing consisting of antisense rna-functionalized nanodiamonds for therapy of non-healing wounds in diabetic individuals
Neuhoferová, Eva; Petráková, V.; Vocetková, K.; Kindermann, Marek; Křivohlavá, Romana; Benson, Veronika
2018 - English
Non-healing wounds are serious complication in diabetic patients and represent an attractive challenge for development of suitable carrier system possessing constant and localized release of therapeutic biomolecule into the wound without any undesired side effects. Given the fact that these non-healing wounds are result of impaired balance in metalloproteinases synthesized by immune cells residing the wounds, gene therapy offering knock down of such enzymes is of great interest. \nHere we challenged a development of functional and biocompatible wound dressing enabling controlled release of trackable carrier loaded with therapeutic siRNA. Our dressing consists of scaffold from degradable polymer nanofibers enriched with fluorescent nanodiamond particles (FND). We have previously shown the nanodiamond particles are great carriers for antisense RNAs. Their advantages represent high biocompatibility, stable luminescence giving us the possibility to track the carrier system in the wound, and effective release of antisense RNA in the wound. Embedding of nanodiamond-siRNA systems into nanofiber scaffold enables continuous release of siRNA and maintaining the stable siRNA concentration in the wound site resulting in a promotion of wound healing. \nWe developed FND-siRNA complexes specific to MMP-9 that efficiently inhibit the expression of target MMP-9 mRNA. The complexes were embedded into core/shell nanofibers from PVA and PCL, visualized by confocal microscopy, and characterized by electron microscopy. Real-time PCR was used to assess the silencing effect of siRNA that has been delivered to target murine fibroblasts by FND released from nanofiber dressing. Nanofiber system with embedded FNDs was applied on wounds in diabetic animal models to evaluate its suitability regarding short and long term toxicity, efficacy, and handling in vivo. \n Keywords: Electrospun nanofibers; fluorescent nanodiamonds; RNA interference Available on request at various institutes of the ASCR

BETA-GLUCANS: WHAT APPLICATIONS? A GENERAL OVERVIEW
Vannucci, Luca; Mishra, Rajbardhan; Lukáč, Pavol; Tenti, Paolo; Rajsiglová, Lenka; Větvička, Václav; Šíma, Petr
2018 - English
Glucans are polysaccharides derived from various sources (e.g. mushrooms, algae, yeast, barley). They can target immune receptors, like Dectin-1 expressed on dendritic cells - antigen presenting cells. Otherwise, interest is rising for their use not only for modulation of immunity, but also of cholesterol levels, or as possible vaccine adjuvants, nanocarriers and functional food components. We will shortly review some aspects in human and veterinarian applications.

Nanodiamonds as an innovative system for intracellular delivery of mirna-34a inprostatic cancer therapy
Bitti, G.; Abate, M.; Neuhoferová, Eva; Kindermann, Marek; Petráková, V.; Boccellino, M.; Quagliuolo, L.; Filová, Eva; Benson, Veronika; Caraglia, M.; Amler, Evžen
2018 - English
The microRNA(miRNA)-34a is an important regulator of tumor suppression. It controls the expression of several target proteins involved in cell cycle, differentiation and apoptosis, and antagonizes processes that are necessary for basic cancer cell viability as well as cancer stemness, metastasis, and chemoresistance. It is downregulated in numerous cancer types, including prostatic cancer, and inhibits malignant growth by repressing genes involved in various oncogenic signaling pathways. Given the anti-oncogenic activity of miR-34a, here we proved the substantial benefits of a new therapeutic concept based on nanotechnology delivery of miRNA mimics. In order to monitor the miRNA-34a replacement, we used a fluorescent nanodiamond particles (FND) system with linked miRNA-34a mimic, which was delivered to PC3 and DU145 prostatic cancer cell lines. We used functionalized nanodiamonds coated with polyethylenimine to transfer miRNA-34a into PC3 and DU145 prostatic cancer cell lines and we measured the zeta-potential of these complexes before using them for in vitro experiments. A replacement of miRNA-34 was observed by monitoring levels of miRNA-34 via real-time PCR. Moreover, our in vitro experiments demonstrated that miRNA-34a replacement, using this FND delivery system, decreased viability and induced apoptosis in prostatic cancer cell lines. Our findings suggest the replacement of oncosuppressor miRNA-34a provides an effective strategy for cancer therapy and the FND-based delivery systems seems to be an excellent strategy for a safe and effective targeting of the tumor.

Effect of nanodiamond particles on neuronal tissue
Šimková, Veronika; Benson, Veronika
2018 - English
High-Pressure High-Temperature nanodiamonds are considered to be highly biocompatible due to\ntheir low acute toxicity, which makes them suitable for biomedical applications. However, next to interaction with the cell membrane, nanoscale allows particles to penetrate the plasma membrane and even accumulate in the cell cytoplasm. Recently it brought up questions regarding sustainable nanoparticle application in vivo and potential toxicity hazards. The neuronal tissue consists of neurons and glial cells, and it is separated by a bloodbrain barrier from the peripheral blood system. Neurons are nerve cells forming a complex network of synapses that carry signals in the brain. The neurons are nourished and protected by glial cells. This project aims to find out whether nanodiamonds pass the blood-brain barrier when applied intravenously as a drug carrier and whether they directly interact with the neuronal tissue.
