Abstract
C-type natriuretic peptide (CNP) exhibits anti-inflammatory activity besides its natriuretic and diuretic functions. The present study aimed to determine the anticancer and synergistic therapeutic activity of CNP against a 7,12-Dimethylbenz[a]anthracene (DMBA)/Croton oil-induced skin tumor mouse model. CNP (2.5 µg/kg body weight) was injected either alone and/or in combination with Cisplatin (CDDP) (2 mg/kg body weight) for 4 weeks. The dorsal skin tumor incidences/growth and mortality rate were recorded during the experimental period of 16 weeks. The serum C-reactive protein (CRP), and lactate dehydrogenase (LDH) levels, infiltrating mast cells, and AgNORs proliferating cells count were analyzed in control and experimental mice. Further, the expression profile of marker genes of proliferation, inflammation, and progression molecules were analyzed using Reverse transcriptase-polymerase chain reaction (RT-PCR)/quantitative PCR (qPCR), western blot, and immunohistochemistry. The DMBA/Croton oil-induced mice exhibited 100% tumor incidence. Whereas, CNP alone, CDDP alone, and CNP+CDDP combination-treated mice exhibited 58%, 46%, and 24% tumor incidence, respectively. Also, a marked reduction in the levels of serum CRP and LDH, the number of infiltrating mast cells count and AgNORs proliferating cells count were noticed in the mice skin sections. Further, a significant reduction in both mRNA and protein expression levels of proliferation, inflammation, and progression markers were noticed in CNP (p < 0.01), CDDP (p < 0.01), and CNP+CDDP combination (p < 0.001) treated mice, respectively. The results of the present study suggest that CNP has anticancer activity. Further, the CNP+CDDP treatment has more promising anticancer activity as compared with CNP or CDDP alone treatment, probably due to the synergistic antiproliferative and anti-inflammatory activities of CNP and CDDP.

Smart drug delivery of p-Coumaric acid loaded aptamer conjugated starch nanoparticles for effective triple-negative breast cancer therapy. Int J Biol Macromol 2022; 195:22-29. [PMID: 34861273 DOI: 10.1016/j.ijbiomac.2021.11.170] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 11/15/2021] [Accepted: 11/23/2021] [Indexed: 12/12/2022]
Abstract
The nano-drug delivery system utilizing the ligand functionalized nanoparticles have a tremendous application in cancer therapeutics. The present study was aimed to fabricate the p-Coumaric acid-loaded aptamer (ligand) conjugated starch nanoparticles (Apt-p-CA-AStNPs) for effective treatment of triple-negative breast cancer (MDA-MB-231). The FT-IR spectrum showed the presence of functional groups associated with para-Coumaric acid (p-CA) and amino starch (AS) in p-CA-AStNPs. Further, the conjugation of aptamer in p-CA-AStNPs was confirmed by agarose gel electrophoresis. Transmission electron microscopic analysis revealed that the synthesized Apt-p-CA-AStNPs were less agglomerated. The zeta size analyzer displayed the average particle size of 218.97 ± 3.07 nm with ȥ-potential -29.2 ± 1.35 mV, and PDI 0.299 ± 0.05 for Apt-p-CA-AStNPs. The drug encapsulation and loading efficiencies were 80.30 ± 0.53% and 10.35 ± 0.85% respectively for Apt-p-CA-AStNPs. Apt-p-CA-AStNPs showed a rapid and bursting release in the initial five hours of the experiment in pH 5.4. A significant change was found in their cytotoxic efficacy between the samples: p-CA, p-CA-AStNPs, and Apt-p-CA-AStNPs. Among the tested samples, Apt-p-CA-AStNPs caused higher cytotoxicity in MDA-MB-231 cells through ROS regulation, nuclear damage, mitochondrial membrane potential, and apoptosis-related protein expressions. Overall, these results proved that Apt-p-CA-AStNPs were efficiently inhibited the MDA-MB-231 cells by regulating apoptosis.

Abstract
Neurodegenerative diseases (NDDs) are one of the leading causes of death and disability in humans. From a mechanistic perspective, the complexity of pathophysiological mechanisms contributes to NDDs. Therefore, there is an urgency to provide novel multi-target agents towards the simultaneous modulation of dysregulated pathways against NDDs. Besides, their lack of effectiveness and associated side effects have contributed to the lack of conventional therapies as suitable therapeutic agents. Prevailing reports have introduced plant secondary metabolites as promising multi-target agents in combating NDDs. Polydatin is a natural phenolic compound, employing potential mechanisms in fighting NDDs. It is considered an auspicious phytochemical in modulating neuroinflammatory/apoptotic/autophagy/oxidative stress signaling mediators such as nuclear factor-κB (NF-κB), NF-E2–related factor 2 (Nrf2)/antioxidant response elements (ARE), matrix metalloproteinase (MMPs), interleukins (ILs), phosphoinositide 3-kinases (PI3K)/protein kinase B (Akt), and the extracellular regulated kinase (ERK)/mitogen-activated protein kinase (MAPK). Accordingly, polydatin potentially counteracts Alzheimer’s disease, cognition/memory dysfunction, Parkinson’s disease, brain/spinal cord injuries, ischemic stroke, and miscellaneous neuronal dysfunctionalities. The present study provides all of the neuroprotective mechanisms of polydatin in various NDDs. Additionally, the novel delivery systems of polydatin are provided regarding increasing its safety, solubility, bioavailability, and efficacy, as well as developing a long-lasting therapeutic concentration of polydatin in the central nervous system, possessing fewer side effects.

Abstract
Although various methods, such as surgery and chemotherapy, are applied to the treatment of OSCC, there are problems, such as functional and aesthetic limitations of the mouth and face, drug side effects, and lymph node metastasis. Many researchers are making efforts to develop new therapeutic agents from plant-derived substances to overcome the side effects that occur in oral cancer treatment. Polydatin is known as a natural precursor of resveratrol, and research on its efficacy is being actively conducted recently. Therefore, we investigated whether polydatin can induce apoptosis and whether it affects cell migration and invasion through the regulation of EMT-related factors in OSCC. Polydatin decreased the survival and proliferation rates of CAL27 and Ca9-22 cells, and induced the release of cytochrome c, a factor related to apoptosis, and fragmentation of procaspase-3 and PARP. Another form of cell death, autophagy, was observed in polydatin-treated cells. In addition, polydatin inhibits cell migration and invasion, and it has been shown to occur through increased expression of E-cadherin, an EMT related factor, and decreased expression of N-cadherin and Slug and Snail proteins and genes. These findings suggest that polydatin is a potential oral cancer treatment.

Insights on the Atmospheric-Pressure Plasma-Induced Free-Radical Polymerization of Allyl Ether Cyclic Carbonate Liquid Layers. Polymers (Basel) 2021; 13:polym13172856.

Abstract
Plasma-induced free-radical polymerizations rely on the formation of radical species to initiate polymerization, leading to some extent of monomer fragmentation. In this work, the plasma-induced polymerization of an allyl ether-substituted six-membered cyclic carbonate (A6CC) is demonstrated and emphasizes the retention of the cyclic carbonate moieties. Taking advantage of the low polymerization tendency of allyl monomers, the characterization of the oligomeric species is studied to obtain insights into the effect of plasma exposure on inducing free-radical polymerization. In less than 5 min of plasma exposure, a monomer conversion close to 90% is obtained. The molecular analysis of the oligomers by gel permeation chromatography coupled with high-resolution mass spectrometry (GPC-HRMS) further confirms the high preservation of the cyclic structure and, based on the detected end groups, points to hydrogen abstraction as the main contributor to the initiation and termination of polymer chain growth. These results demonstrate that the elaboration of surfaces functionalized with cyclic carbonates could be readily elaborated by atmospheric-pressure plasmas, for instance, by copolymerization.

Abstract
We described a technique of a post-process stage to partially remove the poly(vinyl alcohol) (PVA) binder in Poly(lactic-co-glycolic acid) (PLGA) dental scaffolds. The scaffolds were exposed to ultrasonic waves while immersed in an ethanol/acetone solvent mixture that possessed both polar and nonpolar properties. A factorial experiment was conducted in which the scaffolds were treated to three levels of sonication power (pW): 0, 20% (22 W) and 40% (44 W), and soaking duration (t): 5, 15, and 30 min. The treated scaffolds were characterized by FT-IR, optical microscopy, and mechanical (compressive) testing. FT-IR revealed that the amount of PVA decreased with increasing pW and t. Two-way ANOVA revealed that increasing pW and t, respectively, resulted in increasing scaffold surface area to volume (SVR). Sonication and solvent caused structural damage (i.e., unevenness) on the scaffold surface, but the damage was minimal at 20% pW and 30 min. The optimal values of pW and t resulting in enhanced fracture strength, strain and toughness were 20% and 30 min, respectively, which corroborated the findings of minimal structural damage. However, sonication had no significant effects on the scaffold stiffness. Mechanistic analysis of the effects of sonication predicted that the ultrasonic energy absorbed by the scaffold was sufficient to disrupt the van Der Waals bonds between the PVA and PLGA but not high enough to disrupt the covalent bonds within the PLGA. This technique is promising as it can partially remove the PVA from the scaffold, and mitigate problematic issues down the line, such as thermal degradation during sterilization, and undue delay/variability in biodegradation.

Abstract
Secondary injury is the main cause of high mortality and poor prognosis of TBI, which has recently been suggested to be related to ferroptosis. Polydatin, a monocrystalline compound extracted from the rhizome of Polygonum, has been shown to exert potential neuroprotective effects. However, its role and mechanism in the secondary injury of TBI has not been elucidated. In this study, the inhibition of Polydatin on ferroptosis was observed both in the hemoglobin treated Neuro2A cells in vitro and in TBI mouse model in vivo, characterized by reversion of accumulation or deposition of free Fe2+, increased content of MDA, decreased activity of key REDOX enzyme GPx4, cell death and tissues loss. Although Polydatin corrected the increased mRNA levels of ferroptosis signaling molecules GPX4, SLC7A11, PTGS2, and ATP5G3 after TBI, TBI and Polydatin treatment had no significant effect on their protein expression. Notably, Polydatin could completely reverse the decrease of GPx4 activity after TBI in vivo and in vitro, and the effect was stronger than that of the classical ferroptosis inhibitor FER-1 in vitro. Further, Polydatin has been shown to reduce the severity of acute neurological impairment and significantly improve subacute motor dysfunction in TBI mice. Our findings provided translational insight into neuroprotection with Polydatin in TBI by inhibiting ferroptosis mainly depending on the maintenance of GPx4 activity.

Abstract
We describe new method for preparing DNA nanospheres for a self-assembled atenolol@DNA (core/shell) drug delivery system. In this paper, we propose the electrochemical transformation of an alkaline polyelectrolyte solution of DNA into DNA nanospheres. We successfully electrosynthesized DNA nanospheres that were stable for at least 2 months at 4 °C. UV-visible spectra of the prepared nanospheres revealed a peak ranging from 372 to 392 nm depending on the DNA concentration and from 361 to 398.3 nm depending on the electrospherization time. This result, confirmed with size distribution curves worked out from transmission electron microscopy (TEM) images, showed that increasing electrospherization time (6, 12 and 24 h) induces an increase in the average size of DNA nanospheres (48, 65.5 and 117 nm, respectively). In addition, the average size of DNA nanospheres becomes larger (37.8, 48 and 76.5 nm) with increasing DNA concentration (0.05, 0.1 and 0.2 wt%, respectively). Also, the affinity of DNA chains for the surrounding solvent molecules changed from favorable to bad with concomitant extreme reduction in the zeta potential from -31 mV to -17 mV. Principally, the attractive and hydrophobic interactions tend to compact the DNA chain into a globule, as confirmed by Fourier transform infrared spectroscopy (FTIR) and TEM. To advance possible applications, we successfully electro self-assembled an atenolol@DNA drug delivery system. Our findings showed that electrospherization as a cost-benefit technique could be effectively employed for sustained drug release. This delivery system achieved a high entrapment efficiency of 68.03 ± 2.7% and a moderate drug-loading efficiency of 3.73%. The FTIR spectra verified the absence of any chemical interaction between the drug and the DNA during the electrospherization process. X-ray diffraction analysis indicated noteworthy lessening in atenolol crystallinity. The present findings could aid the effectiveness of electrospherized DNA for use in various other pharmaceutical and biomedical applications.

Abstract
Hepatocellular carcinoma (HCC) is one of the most prevalent and deadliest cancers. In this study, the anti-tumor effect of singular degree of polymerization (DP) chitooligosaccharides (COS) (DP 2-5) and the underlay molecular mechanisms were investigated on HCC cell line HepG2. MTT assay showed that (GlcN)5 have the best anti-proliferation effect among the different DP of COS (DP2-5). Furthermore, the administration of (GlcN)5 could decrease mitochondrial membrane potential, release cytochrome c into cytoplasm, activate the cleavage of Caspases9/3, thus inducing mitochondrial-mediated apoptosis in HepG2 cells (accounting for 24.57 ± 2.25%). In addition, (GlcN)5 treatment could increase the accumulation of autophagosomes. Further investigation showed that (GlcN)5 suppressed protective autophagy at the fusion of autophagosomes and lysosomes. Moreover, the inhibition of protective autophagy flux by (GlcN)5 could further decrease cell viability and increase the apoptosis rate. Our findings suggested that (GlcN)5 suppressed HepG2 proliferation through inducing apoptosis via the intrinsic pathway and impairing cell-protective autophagy. COS might have the potential to be an agent for lowering the risk of HCC.

Abstract
Hyperglycemia is associated with impairment of heart function. The current study aimed to investigate the ameliorative effect of polydatin-loaded chitosan nanoparticles (PD-CSNPs), polydatin (PD) and metformin (MET) on diabetic cardiomyopathy in rats. Rats divided into six groups; normal-control, diabetic-control, diabetic + CSNPs (diabetic rats treated with 50 mg/kg blank chitosan nanoparticles), diabetic + PD-CSNPs (diabetic rats treated with PD-CSNPs equivalent to 50 mg/kg of polydatin), diabetic + PD (diabetic rats given 50 mg/kg polydatin), diabetic + MET (diabetic rats given 100 mg/kg metformin), orally and daily for 4 weeks. Treatment of diabetic rats with PD-CSNPs, PD and MET showed a significant reduction in the values of glucose and glycosylated hemoglobin with improvement in heart function biomarkers through decreasing serum creatine kinase and creatine kinase myocardial band activities compared to diabetic control. The treatment agents also suppressed the elevated lipid peroxidation product, increased values of glutathione content, superoxide dismutase, superoxide peroxidase, and catalase activities in the heart of diabetic treated rats. Furthermore, PD-CSNPs, PD and MET decreased heart tissue levels of a pro-inflammatory cytokine; tumor necrosis factor-alpha and nuclear factor-kappa β, upregulation of heart gene expressions; nuclear factor erythroid 2-related factor 2 and heme oxygenase-1. Histological and ultrastructural examinations revealed the ameliorative effect of PD-CSNPs, PD and MET against the harmful of diabetic cardiomyopathy by reducing the cardiac fibers, necrotic cardiac myocytes, inflammatory cell infiltration, and the arrangement of the myofibrils and intercalated discs. In conclusion, the new formula of PD-CSNPs was more effective than PD and MET in amelioration the diabetic cardiomyopathy through its antioxidant, anti-inflammatory and prolonged-release properties.
