Khan MS, Gowda BHJ, Nasir N, Wahab S, Pichika MR, Sahebkar A, Kesharwani P. Advancements in dextran-based nanocarriers for treatment and imaging of breast cancer. Int J Pharm 2023; 643:123276. [PMID: 37516217 DOI: 10.1016/j.ijpharm.2023.123276] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 07/12/2023] [Accepted: 07/26/2023] [Indexed: 07/31/2023]
Abstract
Breast cancer is the most prevalent type of cancer worldwide,particularly among women, with substantial side effects after therapy. Despite the availability of numerous therapeutic approaches, particularly chemotherapy, the survival rates for breast cancer have declined over time. The therapies currently utilized for breast cancer treatment do not specifically target cancerous cells, resulting in significant adverse effects and potential harm to healthy cells alongside the cancer cells. As a result, nanoparticle-based drug delivery systems have emerged. Among various types of nanoparticles, natural polysaccharide-based nanoparticles have gained significant attention due to their ability to precisely control the drug release and achieve targeted drug delivery. Moreover, polysaccharides are biocompatible, biodegradable, easily modifiable, and renewable, which makes them a unique material for nanoformulation. In recent years, dextran and its derivatives have gained much interest in the field of breast cancer therapy. Dextran is a hydrophilic polysaccharide composed of a main chain formed by α-1,6 linked glucopyranoside residues and a side chain composed of residues linked in α-1,2/3/4 positions. Different dextran-antitumor medication conjugates enhancethe efficacy of anticancer agents. With this context, the present review provides brief insights into dextran and its modification. Further, it meticulously discusses the role of dextran-based nanoparticles in breast cancer therapy and imaging, followed by snippets on their toxicity. Lastly, it presents clinical trials and future perspectives of dextran-based nanoparticles in breast cancer treatment.

Perfluorooctanoic acid induces tight junction injury of Sertoli cells by blocking autophagic flux. Food Chem Toxicol 2023; 173:113649. [PMID: 36736878 DOI: 10.1016/j.fct.2023.113649] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/11/2023] [Accepted: 01/31/2023] [Indexed: 02/04/2023]
Abstract
Perfluorooctanoic acid (PFOA), a man-made chemical widely used in consumers, could cause male reproductive toxicity by disrupting blood-testis barrier (BTB) integrity. Autophagy in Sertoli cells is essential for regulation of spermatogenesis and BTB. However, it remains a mystery that whether PFOA-induced BTB injury is associated with autophagy in Sertoli cells. In this study, we found that PFOA dose-dependently disrupted tight junction (TJ) function in Sertoli cells in vivo and in vitro. Furthermore, the results from transmission electron microscopy, Western blot and immunofluorescence analysis revealed that PFOA induced the accumulation of autophagosome in testicular Sertoli cells as well as TM4 cells. Further study confirmed that autophagosome accumulation resulted from the blockage of autophagic degradation because of disruption of autophagosome and lysosome fusion via downregulation of the expression of α-SNAP. In parallel, the overexpressed MMP9 was also observed in vivo and in vitro. Conversely, overexpression of α-SNAP inhibited the expression of MMP9 in TM4 cells. In conclusion, PFOA blocks autophagic flux through downregulating the expression levels of α-SNAP in Sertoli cells, and then induces the accumulation of MMP9 leading to disruption of TJ function. This finding will provide clues for effective prevention and treatment of PFOA-induced male reproductive toxicity.

Abstract
Dextran is by far one of the most interesting non-toxic, bio-compatible macromolecules, an exopolysaccharide biosynthesized by lactic acid bacteria. It has been extensively used as a major component in many types of drug-delivery systems (DDS), which can be submitted to the next in-vivo testing stages, and may be proposed for clinical trials or pharmaceutical use approval. An important aspect to consider in order to maintain high DDS' biocompatibility is the use of dextran obtained by fermentation processes and with a minimum chemical modification degree. By performing chemical modifications, artefacts can appear in the dextran spatial structure that can lead to decreased biocompatibility or even cytotoxicity. The present review aims to systematize DDS depending on the dextran type used and the biologically active compounds transported, in order to obtain desired therapeutic effects. So far, pure dextran and modified dextran such as acetalated, oxidised, carboxymethyl, diethylaminoethyl-dextran and dextran sulphate sodium, were used to develop several DDSs: microspheres, microparticles, nanoparticles, nanodroplets, liposomes, micelles and nanomicelles, hydrogels, films, nanowires, bio-conjugates, medical adhesives and others. The DDS are critically presented by structures, biocompatibility, drugs loaded and therapeutic points of view in order to highlight future therapeutic perspectives.

Abstract
Nanoparticles have several exciting applications nowadays almost in every area. Biomedical field is one of them where nanoparticles show potential for various applications due to their exceptional and exciting properties. The presence of heavy metals in inorganic nanoparticles lead to toxicity in the biological system, therefore, their direct use for drug delivery is restricted. But encapsulating their surface with a non-toxic or biocompatible material makes them a promising material for application in drug delivery system. This review highlights the various characteristics and factors involved in nano-drug delivery system. The understanding of various mechanisms involved during the uptake of nanoparticles by cells, toxicity, surface chemistry and several drug release mechanisms has been discussed. This article also includes various computational studies used to optimise the design and properties of drug delivery system.

Abstract
Gallic acid is a phenolic acid ubiquitously present in numerous medicinal plants and food beverages. Gallic acid is also a potent anti-oxidant phytochemical possessing numerous medicinal potentials against various ailments such as diabetes, hypercholesterolemia and other life-threatening diseases including malignancy. Present study was aimed to evaluate acute and sub-acute toxicity of gallic acid in albino mice. The primary aim of the study was to investigate gallic acid prompted PPAR-α/γ activation associated adverse events. Acute toxicity of gallic acid was determined in albino mice and 28-days sub-acute toxicity study was carried out in male and female albino mice at three dose levels, 100, 300 and 900 mg/kg/day, p.o. LD50 of gallic acid was found to be greater than 2000 mg/kg in mice. Hematological investigation did not show any alteration in transaminases and other blood homeostasis parameters. Gross necropsy showed non-significant alteration upon gallic acid administration. Histopathological finding suggested no significant alteration in tissue histology with slight fatty cells in bone marrow indicating non-significant bone marrow suppression, also no obvious effect was observed on hematological parameters. High dose of gallic acid (900 mg/kg/day) for 28 days did not produce any significant alteration in morphological and behavioral parameters. Histopathological finding also supports safety of gallic acid in mice.

Bakrania AK, Variya BC, Patel SS. Insights from diversified anti-angiogenic models: Role of β-interferon inducer DEAE-Dextran. Pharmacol Rep 2018; 70:549-557.

Abstract
BACKGROUND Angiogenesis, the physiological process involving growth of new blood vessels from preexisting vessels, is essential for organ growth and repair. However, the imbalance in angiogenesis contributes to copious pathologies including cancer. Preceding the development of anti-angiogenic or proangiogenic agents, its evaluation is equally imperative; hence, precise and adequate models required. Valid mammalian models are expensive, time-consuming and not easy to set up, instigating legal and ethical aspects making it necessary to establish models with satisfactory activity and limited drawbacks. METHODS We investigated the activity of DEAE-Dextran on diversified models viz. in vitro cell migration assay, ex vivo aortic ring assay, in vitro chick yolk sac membrane assay and in vivo matrigel plug xenograft model corroborating its anti-angiogenic potential and establishing the best means of evaluation. RESULTS Assorted models were reproducible and correlative to one another. DEAE-Dextran exhibited excellent anti-angiogenic effect in cell migration assay over a duration of 24h compared to the vehicle control fibroblast cell line and aortic ring possessed an alleviated rate of sprouting when treated with DEAE-Dextran with contrast to vehicle control aorta. Similarly, decreased vascular density was observed in DEAE-Dextran treated chick embryos implicating potency of the β-interferon inducer. Augmenting to these results, the matrigel plugs also mitigated vascular net as well as reduced levels of angiogenic marker CD31. CONCLUSION Substantially, DEAE-Dextran leads to anti-tumor activity through anti-angiogenic action and a combination of in vitro and in vivo model is vital for the judgement of anti-angiogenic potential since an in vitro model exempts mammalian-culture considerations.
