Abstract
Docetaxel (DOC) is a potent anticancer molecule widely used to treat various cancers. However, its therapeutic efficacy as a potential anticancer agent has been limited owing to poor aqueous solubility, short circulation time, rapid reticuloendothelial system uptake, and high renal clearance, which consecutively showed poor bioavailability. In the present investigation, we developed polyethylene glycol (PEG) decorated solid lipid nanoparticles (SLN) using the solvent diffusion method to increase the biopharmaceutical properties of DOC. PEG monostearate (SA-PEG2000) was initially synthesized and characterized using various analytical techniques. Afterwards, DOC-loaded SLN was synthesized with and without SA-PEG2000and systematically characterized for in-vitro and in-vivo properties. Spherical-shaped SA-PEG2000-DOC SLN showed hydrodynamic diameter and zeta potential of 177 nm and -13 mV, respectively. During the in-vitro release study DOC-loaded SLN showed a controlledrelease of approximately 54.35 % ±5.46 within 12 h with Higuchi release kinetics in the tumor microenvironment (pH 5.5).In an in-vitro cytotoxicity study,SA-PEG2000-DOC SLN showedsignificantlylower IC50values(p < 0.001)compared to DOC-SLN and DOC aloneagainst prostate cancer cell lines (PC-3). Similarly, an in-vitro cellular uptake study showed a significant increase in intracellular DOC concentration for SA-PEG2000-DOC SLN. Additionally, inin-vivostudies,PEGylated SLN of DOC showed around 2- and 15-fold increase in the maximum concentration of drug (Cmax) and area under the curve (AUC), respectively, as compared to plain DOC solution due to the uniquehydrophilicity and hydrophobicity balance and electrical neutrality of specially designed PEG architect. The biological half-life (t1/2) and mean residence time (MRT) was found to increase from 8.55 and 11.43 to 34.96 and 47.68 h, respectively, with SA-PEG2000-DOC SLN. Moreover, the bio-distribution study indicates high DOC concentration in the plasma which signifies the more pronounced blood residence time of SA-PEG2000-DOC SLN. In a nutshell, SA-PEG2000-DOC SLNwasfound to bea promising and efficient drug delivery platform for the management of Metastatic Prostate cancer.

Role of HIKESHI on Hyperthermia for Castration-Resistant Prostate Cancer and Application of a Novel Magnetic Nanoparticle with Carbon Nanohorn for Magnetic Hyperthermia. Pharmaceutics 2023; 15:pharmaceutics15020626. [PMID: 36839948 PMCID: PMC9967786 DOI: 10.3390/pharmaceutics15020626] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 02/02/2023] [Accepted: 02/07/2023] [Indexed: 02/15/2023] Open
Abstract
The prognosis of castration-resistant prostate cancer (CRPC) is technically scarce; therefore, a novel treatment for CRPC remains warranted. To this end, hyperthermia (HT) was investigated as an alternative therapy. In this study, the analysis focused on the association between CRPC and heat shock protein nuclear import factor "hikeshi (HIKESHI)", a factor of heat tolerance. Silencing the HIKESHI expression of 22Rv1 cells (human CRPC cell line) treated with siRNAs inhibited the translocation of heat shock protein 70 from the cytoplasm to the nucleus under heat shock and enhanced the effect of hyperthermia. Moreover, a novel magnetic nanoparticle was developed via binding carbon nanohorn (CNH) and iron oxide nanoparticle (IONP) with 3-aminopropylsilyl (APS). Tumor-bearing model mice implanted with 22 Rv1 cells were examined to determine the effect of magnetic HT (mHT). We locally injected CNH-APS-IONP into the tumor, which was set under an alternative magnetic field and showed that tumor growth in the treatment group was significantly suppressed compared with other groups. This study suggests that HIKESHI silencing enhances the sensitivity of 22Rv1 cells to HT, and CNH-APTES-IONP deserves consideration for mHT.

Abstract
Thermal elevations experienced by bone during orthopaedic procedures, such as cutting and drilling, exothermal reactions from bone cement, and thermal therapies such as tumor ablation, can result in thermal damage leading to death of native bone cells (osteocytes, osteoblasts, osteoclasts and mesenchymal stem cells). Osteocytes are believed to be the orchestrators of bone remodeling, which recruit nearby osteoclast and osteoblasts to control resorption and bone growth in response to mechanical stimuli and physical damage. However, whether heat-induced osteocyte damage can directly elicit bone remodelling has yet to be determined. This study establishes the link between osteocyte thermal damage and the remodeling cascade. We show that osteocytes directly exposed to thermal elevations (47°C for 1 minute) become significantly apoptotic and alter the expression of osteogenic genes (Opg and Cox2). The Rankl/Opg ratio is consistently down-regulated, at days 1, 3 and 7 in MLO-Y4s heat-treated to 47°C for 1 minute. Additionally, the pro-osteoblastogenic signaling marker Cox2 is significantly up-regulated in heat-treated MLO-Y4s by day 7. Furthermore, secreted factors from heat-treated MLO-Y4s administered to MSCs using a novel co-culture system are shown to activate pre-osteoblastic MSCs to increase production of the pro-osteoblastic differentiation marker, alkaline phosphatase (day 7, 14), and calcium deposition (day 21). Most interestingly, an initial pro-osteoclastogenic signaling response (increase Rankl and Rankl/Opg ratio at day 1) followed by later stage pro-osteoblastogenic signaling (down-regulation in Rankl and the Rankl/Opg ratio and an up-regulation in Opg and Cox2 by day 7) was observed in non-heat-treated MLO-Y4s in co-culture when these were exposed to the biochemicals produced by heat-treated MLO-Y4s. Taken together, these results elucidate the vital role of osteocytes in detecting and responding to thermal damage by means of thermally induced apoptosis followed by a cascade of remodelling responses.

Abstract
Poly(styrene)-b-poly(DL-lactide) (PS-PDLLA) copolymer-based nanoparticles (NPs) of a narrow size distribution, negative zeta potential, and spherical shape were fabricated for the delivery of docetaxel (DCT). The particle size was consistently maintained in serum for 24 hours and a sustained drug release pattern was observed for 10 days in the tested formulations. The cytotoxicity of the developed blank NPs was negligible in prostate cancer (PC-3) cells. Cellular uptake and distribution of the constructed NPs containing a hydrophobic fluorescent dye was monitored by confocal laser scanning microscopy (CLSM) for 24 hours. Anti-tumor efficacy of the PS-PDLLA/DCT NPs in PC-3 cells was significantly more potent than that of the group treated with commercially available DCT, Taxotere (P<0.05). Blood biochemistry tests showed that no serious toxicity was observed with the blank NPs in the liver and kidney. In a pharmacokinetic study of DCT in rats, in vivo clearance of PS-PDLLA/DCT NPs decreased while the half-life in blood increased compared to the Taxotere-treated group (P<0.05). The PS-PDLLA NPs are expected to be a biocompatible and efficient nano-delivery system for anticancer drugs.

Abstract
Prostate cancer is the most common non-cutaneous malignancy in American men. Docetaxel is a useful chemotherapeutic agent for prostate cancer that has been available for over a decade, but the length of the treatment and systemic side effects hamper compliance. Additionally, docetaxel resistance invariably emerges, leading to disease relapse. Docetaxel resistance is either intrinsic or acquired by adopting various mechanisms that are highly associated with genetic alterations, decreased influx and increased efflux of drugs. Several combination therapies and small P-glycoprotein inhibitors have been proposed to improve the therapeutic potential of docetaxel in prostate cancer. Novel therapeutic strategies that may allow reversal of docetaxel resistance include alterations of enzymes, improving drug uptake and enhancement of apoptosis. In this review, we provide the most current docetaxel reversal approaches utilizing nanotechnology. Nanotechnology mediated docetaxel delivery is superior to existing therapeutic strategies and a more effective method to induce P-glycoprotein inhibition, enhance cellular uptake, maintain sustained drug release, and improve bioavailability.
