Int J Biol Macromol 2024; 272:132745. [PMID: 38823734 DOI: 10.1016/j.ijbiomac.2024.132745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 05/26/2024] [Accepted: 05/28/2024] [Indexed: 06/03/2024]
Abstract
Transdermal drug delivery (TDD) has shown great promise in superficial tumor therapy due to its noninvasive and avoidance of the first-pass effect. Especially, passive penetration enhancement technique (PPET) provides the technical basis for TDD by temporarily altering the skin surface structure without requiring external energy. Biomacromolecules and their derived nanocarriers offer a wide range of options for PPET development, with outstanding biocompatibility and biodegradability. Furthermore, the abundant functional groups on biomacromolecule surfaces can be modified to yield functional materials capable of targeting specific sites and responding to stimuli. This enables precise drug delivery to the tumor site and controlled drug release, with the potential to replace traditional drug delivery methods and make PPET-related personalized medicine a reality. This review focuses on the mechanism of biomacromolecules and nanocarriers with skin, and the impact of nanocarriers' surface properties of nanocarriers on PPET efficiency. The applications of biomacromolecule-based PPET in superficial tumor therapy are also summarized. In addition, the advantages and limitations are discussed, and their future trends are projected based on the existing work of biomacromolecule-based PPET.

Wang H, Tang M, Pei E, Shen Y, Wang A, Lin M. Blocking the E2F transcription factor 1/high-mobility group box 2 pathway enhances the intervention effects of α-santalol on the malignant behaviors of liver cancer cells. Int J Biochem Cell Biol 2024; 168:106516. [PMID: 38219975 DOI: 10.1016/j.biocel.2024.106516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 12/13/2023] [Accepted: 01/07/2024] [Indexed: 01/16/2024]
Abstract
In view of the tumor-inhibiting effect of α-santalol in various cancers and the role of E2F transcription factor 1 (E2F1) as an important target for anticancer research, this study investigates the relation between α-santalol and E2F1, as well as the effect of α-santalol on liver cancer progression and the corresponding mechanism. Concretely, liver cancer cells were treated with different concentrations of α-santalol. The IC50 value of α-santalol was determined using Probit regression analysis. Then, transcription factors that are targeted by α-santalol and differentially expressed in liver cancer were screened out. The clinicopathological impact of E2F1 and its targets were evaluated and predicted. The expressions of E2F1 and high-mobility group box 2 (HMGB2) and their correlation in the liver cancer tissues were analyzed by bioinformatics. The effects of E2F1 and HMGB2 on the biological characteristics of liver cancer cells were examined through loss/gain-of-function and molecular assays. With the extension of treatment time, the inhibitory effects of 10 μmol/L and 20 μmol/L α-santalol on cancer cell survival rate were enhanced (P < 0.001). E2F1 and HMGB2 were highly expressed and positively correlated in liver cancer tissues (P < 0.05). High E2F1 expression was correlated with large tumors and high TNM stages (P < 0.05). E2F1 knockdown promoted the effects of α-santalol on dose-dependently inhibiting viability, colony formation, invasion and migration (P < 0.05). Moreover, E2F1 knockdown reduced the IC50 value and HMGB2 level, while HMGB2 overexpression produced opposite effects. HMGB2 overexpression and E2F1 knockdown mutually counteracted their effects on the IC50 value and on the viability and apoptosis of α-santalol-treated liver cancer cells (P < 0.01). Collectively, blocking the E2F1/HMGB2 pathway enhances the intervention effects of α-santalol on the proliferation, migration and invasion of liver cancer cells.

Abstract
Breast cancer continues to be one of the most commonly diagnosed cancers around the world. Despite the decrease in mortality, there has been a steady increase in its incidence. There is much evidence that naturally occurring phytochemicals could prove to be safer alternatives aimed at prevention and development of breast cancer. In the present review, we discuss important phytochemicals, namely capsaicin, alpha-santalol and diallyl trisulphide that are shown to have chemopreventive and anti-tumour properties against breast cancer development. We examined current knowledge of their bioavailability, safety and modulation of molecular mechanisms including their ability to induce apoptotic cell death, promote cell cycle arrest, and inhibit cellular proliferation in different breast cancer cell lines and in vivo models. This review emphasises the importance of these naturally occurring phytochemicals and their potential of becoming therapeutic options in the arsenal against breast cancer development provided further scientific and clinical validation.

AAPS PharmSciTech 2023; 24:119. [PMID: 37173545 DOI: 10.1208/s12249-023-02574-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 04/25/2023] [Indexed: 05/15/2023] Open
Abstract
Ductal carcinoma in situ (DCIS) is currently treated through breast-conserving surgery (lumpectomy), radiation therapy, breast-removing surgery (mastectomy), and hormone therapy to prevent further progression into invasive breast cancer and recurrence. Discrepancies concerning the prognosis of DCIS have sparked controversy about adequate treatment. Considering the severe medical and psychological consequences of mastectomy, developing a treatment approach that arrests the progression of DCIS to the invasive stage without affecting the non-cancerous cells is of utmost importance. In the current review, the problems associated with the diagnosis and management of DCIS have been thoroughly discussed. A summary of the route of administration and drug delivery systems to manage DCIS was also provoked. Innovative ultra-flexible combisomes were also proposed for the effective management of DCIS. Prevention is essential in managing the risk of DCIS and reducing the risk of progression to invasive breast cancer. While prevention is vital, it is not always possible to prevent DCIS, and in some cases, treatment may be necessary. Hence, this review recommends that ultra-flexible combisomes administered as a topical gel provide a non-systemic approach for managing DCIS and thus significantly minimize the side effects and costs associated with existing therapies.

Abstract
Breast cancer is the second most common cancer in women worldwide. Long-term treatment with conventional chemotherapy may result in severe systemic side effects. Therefore, the localized delivery of chemotherapy helps to overcome such a problem. In this article, self-assembling hydrogels were constructed via inclusion complexation between host β-cyclodextrin polymers (8armPEG20k-CD and pβ-CD) and the guest polymers 8-armed poly(ethylene glycol) capped either with cholesterol (8armPEG20k-chol) or adamantane (8armPEG20k-Ad) and were loaded with 5-fluorouracil (5-FU) and methotrexate (MTX). The prepared hydrogels were characterized by SEM and rheological behaviors. The in vitro release of 5-FU and MTX was studied. The cytotoxicity of our modified systems was investigated against breast tumor cells (MCF-7) using an MTT assay. Additionally, the histopathological changes in breast tissues were monitored before and after their intratumor injection. The results of rheological characterization indicated the viscoelastic behavior in all cases except for 8armPEG-Ad. In vitro release results showed a variable range of release profiles from 6 to 21 days, depending on the hydrogel composition. MTT findings indicated the inhibition ability of our systems against the viability of cancer cells depending on the kind and concentration of the hydrogel and the incubation period. Moreover, the results of histopathology showed the improvement of cancer manifestation (swelling and inflammation) after intratumor injection of loaded hydrogel systems. In conclusion, the obtained results indicated the applicability of the modified hydrogels as injectable vehicles for both loading and controlled release of anticancer therapies.

The Assessment of Quality of Products Called Sandalwood Oil Based on the Information Provided by Manufacturer of the Oil on Polish, German, and English Websites. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:9934143. [PMID: 34335846 PMCID: PMC8292048 DOI: 10.1155/2021/9934143] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 06/29/2021] [Accepted: 07/03/2021] [Indexed: 12/01/2022]
Abstract
Background Sandalwood oil is one of the most valuable raw materials worldwide. As a highly valued product, it has its own regulations based on the ISO 3518 standard, which clearly informs producers, distributors, and consumers of the requirements to be met. The aim of this study was to assess the quality of products called sandalwood oil based on the information provided by the manufacturer of the oils on Polish, German, and English websites. Methods A Google search was utilized to collect data on sandalwood oil offered by producers and distributors in Polish and foreign markets. Information from 50 websites in each of the aforementioned languages, including the description of sandalwood oil properties on websites, method for using it, safety limitations, and presence of a product description consistent with the INCI recommendations, was gathered using Microsoft Excel software and was analyzed. The information that enabled us to estimate the quality of the oils was the botanical name of the oil-bearing plant and the price. Good-quality oils were considered to be oils with the botanical name Santalum album in the description and with a price not considerably less than the price of white sandalwood oils sold by reliable distributors who control the quality of the oils by chromatography. Ultimately, the lower price limit for one milliliter of the oil was established as PLN 21. Results and Conclusions. Good-quality sandalwood oils derived from the Santalum album plant at a price equal to or greater than the chromatographically tested items amounted to a negligible percentage of products sold online. Without knowing the botanical name of the essential oil plant and the price range of unadulterated sandalwood oil, the likelihood of buying a reliable product is low on all of the analyzed websites, with the lowest probability being observed on the Polish websites.

Abstract
Breast cancer is the most commonly occurring cancer in women and the second most common cancer overall. The current treatment option for breast cancer includes drug treatment (Chemotherapy and hormone therapy) or surgery (mastectomy and lumpectomy). The major drawbacks of chemotherapy include rapid metabolism, limited ductal exposure, lower bioavailability, higher elimination rate, undesirable side effects, and high dose of drug. Localized application of drug to breast achieves higher drug levels at the tumor site and reduces systemic drug distribution. Permeation of drug by local application is mainly by transepidermal and transductal routes. The multiple duct openings of mammary papilla provide a higher permeable surface for transport of drug. Various formulation approaches like conjugated nanocarriers, microemulsion, nanoemulsion, liposomes, microneedles and iontophoresis are used to achieve a tailored and targeted drug delivery to underlying breast tissue. Localized transport of drug via transpapillary route has developed a novel and effective non-invasive drug delivery approach to achieve a systemic drug level at the tumor site in the management of breast cancer.

Targeted Transdermal Delivery of Curcumin for Breast Cancer Prevention. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16244949.

Abstract
N.B. This manuscript is based on the research concept submitted to the "Global Challenge to Prevent Breast Cancer" idea showcase and competition, launched in 2018 by the California Breast Cancer Research Program (CBCRP), which was subsequently selected for publication. The hypothesis, methods, and discussion put forth here are thus proposed concept studies, which could eventually be elucidated in the future. Curcumin is an herbal supplement, shown in preclinical studies to have antioxidant, anti-inflammatory, and antitumoral properties that we believe can be harnessed for breast cancer prevention. However, due to its poor absorption when consumed orally, curcumin's anticancer effects have not yet been exploited to their full therapeutic potential. Incorporating existing research that focuses on the optimization of curcumin's bioavailability and the latest transdermal delivery technology, we propose, below, a hypothetical in vivo study to test whether a targeted daily dose of bioavailable curcumin has a cytotoxic effect on cancer cells, potentially reducing the incidence of breast cancer over time. Our ultimate objective is to adopt innovative methods to create curcumin-infused bio-textiles offering transdermal, targeted drug delivery, simply through contact with the skin. We would use this fabric to create disposable bra inserts for an effortless, daily breast cancer prevention regimen for healthy women. It would be essential that the cost of these inserts remain reasonable, but if successful, curcumin is readily available, affordable and non-toxic, and could thus be a preventive measure that would be beneficial for women from all socio-economic backgrounds.

Abstract
While the feasibility of transpapillary drug delivery has previously been established, localized transport via the mammary ducts may be improved with tailored drug delivery formulations. The objective of this study was to investigate the impact of nanoemulsion encapsulation on transpapillary delivery in vitro. Nanoemulsion formulations composed of isopropyl myristate and Tween 80 encapsulating a fluorescent dye were applied topically on porcine nipples using a Franz diffusion cell. A combination of dye extraction and fluorescence image analysis was used to quantify the total amount of dye retained within the nipple and to characterize the penetration routes. After diffusion for 6 hours, the amount of dye deposited in the nipple was proportional to the formulation’s water concentration. The 90% water formulation deposited significantly more dye via both the stratum corneum and mammary ducts, while the 80% and 70% water formulations moderately increased ductal penetration, but minimally altered stratum corneum penetration as compared to the control solution. Similar trends were found after diffusion for 48 hours; however, the overall impact was diminished, likely due to the nanoemulsion’s topical instability. This study indicates that drug delivery vehicles, nanoemulsions specifically, enhance delivery of encapsulated molecules via the stratum corneum and mammary ducts in a formulation-dependent basis.

Abstract
This study examined the efficacy of the percutaneous delivery of a tetramethylpyrazine-loaded microemulsion (TMP-ME) on skin pretreated with microneedles (MN). The TMP-ME formulation was optimized in vitro with skin permeation experiments, using a uniform experimental design, guided by a pseudo-ternary phase diagram, in which the TMP skin permeation level and mean particle size were indices. The effects of MN pretreatment on skin permeation by TMP-ME were assessed using in vitro skin permeation, in vivo skin microdialysis, and pharmacokinetic studies in rats. The influence of MN pretreatment on the skin barrier function was evaluated by measuring the electrical resistance of rat skin before and after MN insertion. In the optimal formulation of TMP-ME, the weight percentages of Maisine® 35-1 (oil phase), Labrasol® (surfactant), and Transcutol® P (co-surfactant) were 7%, 30% and 10%, respectively, with 1.5% TMP loading. In the in vitro skin permeation study, MN-assisted TMP-ME exhibited a two-fold increase in a 24-h cumulative TMP permeation compared with TMP-ME alone (p < 0.05). In the skin microdialysis study, TMP in MN-assisted TMP-ME exhibited a 1.25-fold increase in Cmax, a 0.93-fold decrease in Tmax, and a 0.88-fold increase in AUC0–t (p < 0.05). Similarly, in the pharmacokinetic study, TMP in MN-assisted TMP-ME exhibited a 2.11-fold increase in Cmax, a 0.67-fold decrease in Tmax, and a 1.07-fold increase in AUC0–t (p < 0.05). The percutaneous electrical resistance of rat skin before and after MN insertion was 850 ± 50 Ω/cm2 and 283 ± 104 Ω/cm2 respectively, indicating that MN dramatically compromises the skin barrier. These results suggest that MN assistance increases the skin permeation rate and the extent of percutaneous absorption of TMP-ME, and that the mechanism may involve the reversible barrier perturbation effect. The rate and extent of percutaneous absorption of TMP-ME can be significantly enhanced by MN assistance, possibly because MN causes a reversible barrier perturbation effect on skin.

Abstract
Alpha-santalol is a naturally occurring sesquiterpene that is derived from sandalwood oil. Its wide range of health benefits have been attributed to the modulation of various signalling pathways involved in the development of a particular disease. For example, the antitumour and cancer preventive properties of alpha-santalol have been shown to involve cell death induction through apoptosis and cell cycle arrest in various cancer models. A marked decrease in inflammatory markers have also been shown with alpha-santalol administration in skin tissue models. The current review is aimed at bringing the most recent advances of alpha-santalol against various disease-specific models and highlighting its associated mechanistic details.
