Key components of this transformation include the development of a robust research and development (R&D) ecosystem and biotechnology-based industry. The Kingdom has recently formed the Research, Development and Innovation Authority (RDIA) to regulate and fund research with Health and Wellness being among its top priorities, and the Saudi National Institute of Health (SNIH) to support translational health research and clinical trials. In addition, the country has launched its National Biotechnology Strategy with a bold goal of becoming a biotechnology hub in the region by 2030 and globally by 2040. Toxicology research is central to these transformations. Historically, it has served as a cornerstone to biomedical and healthcare R&D. Today, with advancements in materials science and the integration of multiple technologies (e.g., biotechnology, nanotechnology, artificial intelligence, etc.) across the different industry sectors, it has become more critical than ever to assess safety early in the development process. In this editorial, we discuss the essence of toxicology research in realizing the country's ambitious goals of Vision 2030 and beyond, particularly in the development of the healthcare and biomedical R&D sectors and advancing a biotechnology-based industry. We first provide an overview of the current state of toxicology research and discuss its critical role in advancing the goals of Vision 2030.

Without appropriate interventions, annual ABR-associated deaths have been projected to reach 10 million by 2050 worldwide. Hence, it is critical to develop novel therapeutic interventions that would be able to tackle ABR by targeting mainly the pathogenic microbes, while lessening harm to beneficial microbes. There is an increasing research interest in CRISPR-Cas (CC) systems owing to their potential in controlling and preventing horizontal gene transfer and spread of antibiotic resistance. In addition, CC systems offer several advantages, including high efficiency, rapid turnaround time, low cost, and easy design, which allow these systems to effectively and precisely target antibiotic-resistant bacteria. CRISPR-based gene therapy offers numerous benefits; however, the major limitation in clinical translation is the safe and effective delivery of CRISPR components to target organs or cells, thus hindering its potential in therapeutic interventions. Nanocarriers (NCs) can help the CC systems to overcome their off-target effects by precisely delivering the systems to the target cells. NCs can also be engineered for target site release, payload protection, and high specificity, which can further ensure delivery of the components of CC in the target cells or regions without harming surrounding tissues. This review summarizes the principles and mechanisms of CC systems, highlights their applications against antibiotic-resistant bacteria, and discusses emerging nanocarrier-based delivery strategies that may enhance the clinical utility of CRISPR-Cas technologies in managing ABR.</p>","PeriodicalId":49257,"journal":{"name":"Saudi Pharmaceutical Journal","volume":"34 1","pages":"5"},"PeriodicalIF":3.4,"publicationDate":"2026-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12852552/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146068041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is necessary to reevaluate this risk. This study aimed to quantify the signal of drug eruption associated with the use of tetracyclines. Also, the signal of drug eruption with the use of two other antimicrobial drugs-macrolides and fluoroquinolones-was investigated for comparison. A pharmacovigilance case/noncase study was conducted using the U.S. FDA Adverse Event Reporting System (FAERS). Reports of drug eruptions using the preferred term were retrieved from the database from 2020-2025 quarter 1. The associations between the risk of drug eruption and the three antibiotic classes were quantified using disproportionality analysis utilizing both Bayesian and traditional statistical analyses, including the reporting odds ratio (ROR), proportional reporting ratio (PRR), empirical Bayes geometric mean (EBGM) and information component (IC). All three antibiotic classes were significantly associated with the risk of drug eruption. However, compared with fluoroquinolones and macrolides, tetracyclines were more strongly associated with drug eruption. Disproportionality analysis revealed that the ROR for tetracycline was 6.65 (95% confidence interval (CI), 4.00-11.09) in 2020; in 2024, it was 30.75 (95% CI, 24.46-38.67). For macrolides, the RORs were 2.16 (95% CI, 1.20-3.92) and 10.12 (95% CI, 7.16-14.31) in 2020 and 2024, respectively. The RORs for fluoroquinolones were 4.57 (95% CI, 3.20-6.52) in 2020 and 2.27 (95% CI, 1.31-3.92) in 2024. Males were predominant in the tetracycline group (74%), and females were predominant in the macrolide group (56%). Approximately 41% and 40% of patients in the fluoroquinolone and macrolide classes, respectively, were hospitalized. All three antibiotic classes were associated with the signal of drug eruption.

One of the main drivers is the dysregulation of the downstream signalling machinery. The PI3K, AKT, and mTOR signalling pathways play a pivotal role in cellular sustenance, growth, metabolism, and proliferation. In prostate cancer this pathway is generally altered due to the mutation or deletion of the PTEN (phosphatase and tensin homolog) gene and unnecessary activities of some components of PI3K, AKT, or mTOR. Extracellular communication of the androgen receptor (AR) with a wide array of oncogenic signatures is a primary evasion mechanism of cancer therapy and metastasis. This review focuses on the structure and function of the PI3K/AKT/mTOR pathway to better understand its role in prostate tumor biology. Furthermore, current therapeutic strategies that combinatorically target individual components of this pathway, such as allosteric and ATP-competitive AKT inhibitors, isoform-selective PI3K inhibitors, first- and second-generation mTOR inhibitors, are under consideration. The study particularly focuses on the combined use of immunotherapy (checkpoint inhibitors), chemotherapy (docetaxel), and androgen deprivation therapy (ADT), which are designed to break through the resistance-generating mechanisms and increase clinical efficacy. Overall, the findings support the need to conduct comprehensive preclinical and clinical studies on these alternative treatment regimens, and the eventual goal is to develop new treatment options for prostate cancer. The evidence of the pathway-specific therapy approach for the treatment of prostate cancer in recent clinical trials still failed to give a conclusive result. The current discussion also investigates the emerging areas of focus and perfection of combination regimens.

A cross-sectional questionnaire was administered to two key stakeholder groups: supply chain management (SCM) personnel and healthcare professionals (HCPs).

Poor demand forecasting and limited sourcing capabilities were identified as the primary contributing factors.

Additionally, many respondents reported that staff time is often wasted in the search for alternative therapies, which may also be of short supply. Interestingly, more than 70% of respondents from both groups expressed robust support for the adoption of advanced technologies such as artificial intelligence (AI) and machine learning (ML) to enhance forecasting and inventory management.

The purpose of this investigation was to clarify the processes by which 5e reduces hyperglycemia through tolerance tests, metabolic hormone assessment, and evaluation of anti-apoptotic effects on pancreatic tissue. Forty male Sprague-Dawley rats allocated to five categories: control, diabetic, diabetic administered glibenclamide (10 mg/kg), and diabetic treated with 5e at two doses (10 and 15 mg/kg). Over two weeks, blood glucose and tolerance tests were performed, and on day 15, blood and pancreatic tissues were collected for analysis of insulin, glucagon, lipase, and amylase, along with histological evaluation. Both 5e and glibenclamide reduced blood glucose by approximately 36%, while the higher dose of 5e lowered glycemia by 50%. All treated groups showed improved glycemic control in tolerance tests, with the 15 mg/kg 5e group demonstrating the greatest glucose clearance and insulin sensitivity. Compound 5e modulated insulin, glucagon, and lipase levels, indicating metabolic improvement, with the strongest effects at the higher dose.
