Seyhan SA, Alkaya DB, Cesur S, Sahin A. Investigation of the antitumor effect on breast cancer cells of the electrospun amygdalin-loaded poly(l-lactic acid)/poly(ethylene glycol) nanofibers. Int J Biol Macromol 2023; 239:124201. [PMID: 37001771 DOI: 10.1016/j.ijbiomac.2023.124201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/15/2023] [Accepted: 03/23/2023] [Indexed: 04/03/2023]
Abstract
In this study, PLA/PEG nanofibers (NFs) loaded with amygdalin (AMG) and bitter almond kernels extract were produced by electrospinning to prevent local breast cancer recurrence, and the effect of produced NFs on the MCF-7 cell line was investigated in vitro. The electrospun NFs were characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), thermal analysis (DSC) and tensile strength and physical analyzes were performed. Loading of AMG to nanofibers increased fiber diameters from 827.93 ± 174.507 nm to 1855.32 ± 291.057 μm. When drug release results were analyzed, the NFs showed a controlled release profile extending up to 10 h. The encapsulation efficiency of AMG-loaded NFs was calculated at 100 ± 0,01 %, 94 ± 0,02 %, and 88 ± 0,02 %. When in vitro cytotoxicity results were analyzed, showed that all NFs are effective in inducing cytotoxicity against MCF-7 breast cancer cells. Importantly, 20 mg AMG-loaded NFs displayed effectively higher cytotoxic effects against breast cancer cells relative to the other NFs. Considering all the results, AMG-loaded NFs can give sustained release of drugs at the local sites. Therefore, AMG-loaded nanofibers can reduce the risk of local recurrence of cancer after surgery and can be directly implanted into solid tumor cells for treatment.

Bioengineering (Basel) 2022; 9:bioengineering9090427. [PMID: 36134974 PMCID: PMC9495790 DOI: 10.3390/bioengineering9090427] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 08/24/2022] [Accepted: 08/26/2022] [Indexed: 11/16/2022] Open
Abstract
Skin diseases are commonly treated with antihistamines, antibiotics, laser therapy, topical medications, local vitamins, or steroids. Since conventional treatments for wound healing (skin allografts, amnion, xenografts, etc.) have disadvantages such as antigenicity of the donor tissue, risk of infection, or lack of basement membrane, skin tissue engineering has become a popular new approach. The current study presents the design and fabrication of a new wound-dressing material by the addition of Juglone (5-hydroxy-1,4-naphthoquinone) to a 25% Polycaprolactone (PCL) scaffold. Juglone (J) is a significant allelochemical found in walnut trees and, in this study is used as a bioactive material. The effects of different amounts of J (1.25, 2.5, 5, 7.5, and 10 mg) on the biocompatibility, mechanical, chemical, thermal, morphological, and antimicrobial properties of the 3D-printed 25% PCL scaffolds were investigated. The addition of J increased the pore diameter of the 25% PCL scaffold. The maximum pore size (290.72 ± 14 µm) was observed for the highest amount of J (10 mg). The biocompatibility tests on the scaffolds demonstrated biocompatible behavior from the first day of incubation, the 25% PCL/7.5 J scaffold having the highest viability value (118%) among all of the J-loaded scaffolds. Drug release of J into phosphate buffered saline (PBS) at pH 7.4 showed that J was completely released from all 25% PCL/J scaffolds within 7 days of incubation.

Polymers (Basel) 2022; 14:polym14142881. [PMID: 35890657 PMCID: PMC9322509 DOI: 10.3390/polym14142881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 07/11/2022] [Accepted: 07/14/2022] [Indexed: 12/03/2022] Open
Abstract
Plastic materials are one of the significant components of construction materials omnipresent in all areas of the industry and everyday life. One of these plastics is polyethylene terephthalate (PET). Due to its processing properties, with a simultaneous low production cost, PET has been used in many industrial applications, including the production of various types of bottles. Moreover, the high consumption of PET bottles causes the accumulation of large amounts of their waste and necessitates finding an effective way to recycle them. Electrospinning is a well-known non-complicated method for the fabrication of nonwovens from polymers and composites, which can be utilized in many fields due to their outstanding properties. In addition, it might be a promising technique for the recycling of plastic materials. Therefore, in this study, the electrospinning approach for the recycling of two types of PET bottle wastes—bottles made of virgin PET and bottles made of recycled PET (PET bottles) has been utilized, and a comparison of the properties of the obtained materials have been performed. The fibers with diameters of 1.62 ± 0.22, 1.64 ± 0.18, and 1.89 ± 0.19 have been produced from solutions made of virgin PET granulate, PET bottles, and PET bottles made of recycled bottles, respectively. Obtained fibers underwent morphological observation using a scanning electron microscope. Physico-chemical properties using FTIR, gel chromatography, and differential scanning calorimetry have been evaluated, and mechanical properties of obtained mats have been investigated. Cytotoxicity tests using the L929 mouse fibroblast cell line revealed no cytotoxicity for all tested materials.
