Abstract
Rho family GTPases regulate cellular processes and promote tumour growth and metastasis; thus, RhoA is a potential target for tumour metastasis inhibition. However, limited progress has been made in the development of RhoA targeting anticancer drugs. Here, we synthesised benzo[b]thiophene-3-carboxylic acid 1,1-dioxide derivatives based on a covalent inhibitor of RhoA (DC-Rhoin), reported in our previous studies. The observed structure-activity relationship (contributed by carboxamide in C-3 and 1-methyl-1H-pyrazol in C-5) enhanced the anti-proliferative activity of the derivatives. Compound b19 significantly inhibited the proliferation, migration, and invasion of MDA-MB-231 cells and promoted their apoptosis. The suppression of myosin light chain phosphorylation and the formation of stress fibres confirmed the inhibitory activity of b19 via the RhoA/ROCK pathway. b19 exhibited a different binding pattern from DC-Rhoin, as observed in molecular docking analysis. This study provides a reference for the development of anticancer agents targeting the RhoA/ROCK pathway.

Abstract
Breast cancer remains a significant global health challenge, spurring ongoing investigations into innovative treatment approaches. Low-level laser therapy (LLLT) has emerged as a promising non-invasive therapeutic avenue of interest. This research delves into the impact of LLLT on the cytotoxicity of the MCF-7 breast cancer cell line, employing lasers emitting various wavelengths. The objective is to assess whether diverse LLLT wavelengths elicit disparate cytotoxic responses, shedding light on LLLT's potential as a targeted breast cancer treatment. MCF-7 cell cultures were subjected to lasers of varying wavelengths, including blue (473 nm), red (660 nm), and near-infrared (780 nm). Each wavelength was delivered at four different power levels: 10, 25, 45, and 65 mW, with exposure durations of 60, 300, 600, and 900 s. Cellular responses, encompassing factors such as cell viability, and cytotoxicity were assessed using WST-1 assays technique. Statistical analysis was performed to discern the wavelength-specific impacts of low-level laser therapy (LLLT) on MCF-7 cells. The study revealed that the blue laser had the least noticeable adverse impact on MCF-7 breast cancer cell lines, leading to the highest cell survival rate of 107.62% after 24 h. The most severe toxicity occurred when the laser was used at 45 mW for 900 s, resulting in cell viability ranging from 81.85% to 107.62%. As for cell viability after exposure to the red laser, the mildest harmful effect was observed at 45 mW power for 60 s, resulting in a cell survival rate of 147.62%. Conversely, the most significant toxic response occurred at 10 mW power for 60 s, resulting in a cell viability of 91.56%. In contrast, when employing infrared laser irradiation, the least substantial cytotoxic effect on MCF-7 cells was observed at 10 mW power for 600 s, resulting in the highest cell viability of 109.37% after 24 h. The most pronounced cytotoxic effect was observed by infrared laser (780 nm) at 25 mW power for 900 s, leading to the lowest viability of 32.53%.

Abstract
The continuously increasing rate of breast cancer is one of the major threats to female health worldwide. Recently, palladium complexes have emerged as impressive candidates with effective biocompatibility and anticancer activities. Hence, in the present study, we report a new series of palladium complexes bearing NNS pincer ligands for cytotoxicity studies. The reaction of thiophenol/4-chlorothiophenol/4-methylthiophenol/4-methoxythiophenol with 2-bromo-N-quinolin-8-yl-acetamide in the presence of sodium hydroxide in ethanol at 80 °C gave [C9H6N-NH-C(O)-CH2-S-Ar] [Ar = C6H5 (L1), C6H4Cl-4 (L2), C6H4Me-4 (L3), and C6H4-OMe-4 (L4)]. The corresponding reaction of L1-L4 with Na2PdCl4 in methanol at room temperature for 3 h resulted in complexes [(L1-H)PdCl] (C1), [(L2-H)PdCl] (C2), [(L3-H)PdCl] (C3), and [(L4-H)PdCl] (C4). All new compounds have been characterized by spectroscopic analyses. The structures of complexes C1, C3, and C4 have also been determined from single-crystal X-ray diffraction data. The cytotoxicities of L1-L4 and C1-C4 have been investigated for breast cancer 4T1 and pancreatic cancer MIA-PaCa-2 cells. The IC50 values for complexes C2 and C3 were observed to be comparable to or higher than those of cisplatin. The stressed morphology and cell death of cancerous cells were successfully observed through cellular morphology analysis and the assessment of cytoskeleton damage.

Abstract
Since the establishment of regulations for exposure to extremely low-frequency (0-300) Hz electromagnetic fields, scientific opinion has prioritised the hypothesis that the most important parameter determining cellular behaviour has been intensity, ignoring the other exposure parameters (frequency, time, mode, waveform). This has been reflected in the methodologies of the in vitro articles published and the reviews in which they are included. A scope review was carried out, grouping a total of 79 articles that met the proposed inclusion criteria and studying the effects of the different experiments on viability, proliferation, apoptosis, oxidative stress and the cell cycle. These results have been divided and classified by frequency, intensity, exposure time and exposure mode (continuous/intermittent). The results obtained for each of the processes according to the exposure parameter used are shown graphically to highlight the importance of a good methodology in experimental development and the search for mechanisms of action that explain the experimental results, considering not only the criterion of intensity. The consequence of this is a more than necessary revision of current exposure protection regulations for the general population based on the reductionist criterion of intensity.

Atwan QS, Al-Ogaidi I. Enhancing the therapeutic potential of curcumin: a novel nanoformulation for targeted anticancer therapy to colorectal cancer with reduced miR20a and miR21 expression. Biomed Mater 2024; 19:025020. [PMID: 38215475 DOI: 10.1088/1748-605x/ad1dfc] [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: 09/09/2023] [Accepted: 01/12/2024] [Indexed: 01/14/2024]
Abstract
Curcumin (Cur) possesses remarkable pharmacological properties, including cardioprotective, neuroprotective, antimicrobial, and anticancer activities. However, the utilization of Cur in pharmaceuticals faces constraints owing to its inadequate water solubility and limited bioavailability. To overcome these hurdles, there has been notable focus on exploring innovative formulations, with nanobiotechnology emerging as a promising avenue to enhance the therapeutic effectiveness of these complex compounds. We report a novel safe, effective method for improving the incorporation of anticancer curcumin to induce apoptosis by reducing the expression levels of miR20a and miR21. The established method features three aspects that, to our knowledge, have not been formally verified: (1) use of a novel formula to incorporate curcumin, (2) use of all biocompatible biodegradable materials to produce this formula without leaving harmful residues, and (3) an incorporation process at temperatures of approximately 50 °C. The formula was prepared from lecithin (LE), and chitosan (CH) with an eco-friendly emulsifying agent and olive oil as the curcumin solvent. The formula was converted to nanoscale through ultrasonication and probe sonication at a frequency of 20 kHz. Transmission electron microscopy showed that the nano formula was spherical in shape with sizes ranging between 49.7 nm in diameter and negative zeta potentials ranging from 28 to 34 mV. Primers miR20a and miR21 were designed for molecular studies. Nearly complete curcumin with an encapsulation efficiency of 91.1% was established using a straight-line equation. The nano formula incorporated with curcumin was used to prepare formulations that exhibited anticancer activities. The apoptosis pathway in cancer cells was activated by the minimum inhibitory concentration of the nano formula. These findings suggest the potential of this nanoformulation as an effective and selective cancer treatment that does not affect the normal cells.

Improving the targeted delivery of curcumin to esophageal cancer cells via a novel formulation of biodegradable lecithin/chitosan nanoparticles with downregulated miR-20a and miR-21 expression.

Abstract
Nanoencapsulation, employing safe materials, holds substantial promise for enhancing bioactive compounds' delivery, stability, and bioactivity. In this study, we present an innovative and safe methodology for augmenting the incorporation of the anticancer agent, curcumin, thereby inducing apoptosis by downregulating miR20a and miR21 expression. Our established methodology introduces three pivotal elements that, to our knowledge, have not undergone formal validation: (1) Novel formulation: We introduce a unique formula for curcumin incorporation. (2) Biocompatibility and biodegradability: our formulation exclusively consists of biocompatible and biodegradable constituents, ensuring the absence of detrimental residues or undesirable reactions under varying conditions. (3) Low-temperature incorporation: Curcumin is incorporated into the formulation at temperatures approximating 50 °C. The formulation comprises lecithin (LE), chitosan (CH), an eco-friendly emulsifying agent, and olive oil as the solvent for curcumin. Nanoscale conversion is achieved through ultrasonication and probe sonication (20 kHz). Transmission electron microscopy (TEM) reveals spherical nanoparticles with diameters ranging from 29.33 nm and negative zeta potentials within the -28 to -34 mV range. Molecular studies involve the design of primers for miR20a and miR21. Our findings showcase a remarkable encapsulation efficiency of 91.1% for curcumin, as determined through a linear equation. The curcumin-loaded nanoformulation demonstrates potent anticancer activity, effectively activating the apoptosis pathway in cancer cells at the minimum inhibitory concentration. These results underscore the potential of our nanoformulation as a compelling, cancer-selective treatment strategy, preserving the integrity of normal cells, and thus, warranting further exploration in the field of cancer therapy.

Abstract
Lung cancer is indeed a major cause of cancer-related deaths worldwide. The development of tumors involves a complex interplay of genetic, epigenetic, and environmental factors. Epigenetic mechanisms, including DNA methylation (DNAm), histone modifications, and microRNA expression, play a crucial role in this process. Changes in DNAm patterns can lead to the silencing of important genes involved in cellular functions, contributing to the development and progression of lung cancer. MicroRNAs and exosomes have also emerged as reliable biomarkers for lung cancer. They can provide valuable information about early diagnosis and treatment assessment. In particular, abnormal hypermethylation of gene promoters and its effects on tumorigenesis, as well as its roles in the Wnt signaling pathway, have been extensively studied. Epigenetic drugs have shown promise in the treatment of lung cancer. These drugs target the aberrant epigenetic modifications that are involved in the development and progression of the disease. Several factors have been identified as drug targets in non-small cell lung cancer. Recently, combination therapy has been discussed as a successful strategy for overcoming drug resistance. Overall, understanding the role of epigenetic mechanisms and their targeting through drugs is an important area of research in lung cancer treatment.
