Abstract
Lung cancer remains a leading cause of cancer-related mortality worldwide. Despite advances in targeted therapies and immunotherapies, drug resistance and adverse effects necessitate novel therapeutic strategies. This study employs a computational approach integrating drug-target interaction networks, gene expression profiles, and drug-drug interaction data to identify potential drug targets and repurpose existing drugs for lung cancer treatment. We analyzed transcriptomic data from lung cancer patients and constructed a protein-protein interaction network to pinpoint hub genes. Subsequently, we screened FDA-approved drugs against these targets using molecular docking and drug repurposing databases. Our analysis identified several promising candidates, including [Drug A] and [Drug B], which exhibited high binding affinities and favorable pharmacokinetic profiles. In vitro validation in lung cancer cell lines confirmed the anti-proliferative effects of these drugs. These findings provide a foundation for clinical trials and highlight the utility of computational drug repurposing in oncology.
1. Introduction
Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer death globally, accounting for about 1.8 million deaths annually. Non-small cell lung cancer (NSCLC) constitutes approximately 85% of cases, with a five-year survival rate of only 15% for advanced stages. Despite the advent of targeted therapies such as EGFR inhibitors and ALK inhibitors, resistance inevitably develops, underscoring the urgent need for novel therapeutic options.
Drug repurposing, the application of existing drugs to new indications, offers a cost-effective and time-efficient alternative to de novo drug development. Computational approaches, including network pharmacology and molecular docking, have accelerated the identification of repurposing candidates. In this study, we integrate transcriptomic data, protein-protein interaction networks, and drug-target databases to systematically identify potential drug targets and repurpose existing drugs for lung cancer. Our findings highlight several promising candidates that warrant further preclinical and clinical investigation.

Frequently Asked Questions
What is drug repurposing?
Drug repurposing is the process of identifying new therapeutic uses for existing approved drugs, which can significantly reduce the time and cost of drug development.
How were drug targets identified in this study?
We analyzed gene expression data from lung cancer patients and constructed a protein-protein interaction network to identify hub genes that are central to cancer progression. These hub genes were considered as potential drug targets.
Which drugs were found to be promising?
Our computational screening identified several FDA-approved drugs, including [Drug A] and [Drug B], which showed high binding affinity to the identified targets and demonstrated anti-proliferative effects in lung cancer cell lines.
What is the significance of this research?
This research provides a cost-effective strategy to accelerate drug discovery for lung cancer by repurposing existing drugs, potentially leading to faster clinical translation and improved patient outcomes.
What are the limitations of this study?
The study relies on computational predictions and in vitro validation; further in vivo studies and clinical trials are required to confirm efficacy and safety in humans.

Adverse Events Reporting System for Vaccine Safety Surveillance: A Comprehensive Analysis
Background: Adverse events following immunization (AEFI) are critical to monitor for vaccine safety. This study evaluates the performance of an adverse events reporting system (AERS) integrated with a vaccine adverse event reporting system (VAERS) to enhance surveillance. Methods: We analyzed data from multiple sources including the Vaccine Adverse Event Reporting System (VAERS), the Vaccine Safety Datalink (VSD), and the Clinical Immunization Safety Assessment (CISA) network. A novel framework was developed to integrate these systems, incorporating natural language processing for signal detection. Results: The integrated system improved detection of rare adverse events by 25% compared to traditional methods. The system identified new safety signals for influenza and COVID-19 vaccines. Conclusions: The proposed AERS framework enhances vaccine safety surveillance, enabling timely identification of potential risks. Integration of diverse data sources and advanced analytics is essential for robust pharmacovigilance.
Efficacy and Safety of Ferric Carboxymaltose in Treating Iron Deficiency Anemia: A Meta-Analysis of Randomized Controlled Trials
Background: Iron deficiency anemia (IDA) is a global health concern, and intravenous ferric carboxymaltose (FCM) has emerged as a promising treatment. This meta-analysis aimed to evaluate the efficacy and safety of FCM compared to other iron therapies or placebo in adults with IDA. Methods: We systematically searched PubMed, Embase, and Cochrane Library up to December 2024. Randomized controlled trials (RCTs) comparing FCM with active comparators or placebo in adults with IDA were included. The primary outcomes were change in hemoglobin (Hb) from baseline, and safety outcomes included adverse events (AEs) and serious adverse events (SAEs). Pooled estimates were calculated using random-effects models. Results: A total of 15 RCTs involving 4,856 patients were included. FCM significantly increased Hb levels compared to placebo (mean difference [MD] 1.2 g/dL, 95% CI 0.9-1.5) and was non-inferior to other intravenous iron preparations. The risk of AEs was similar between FCM and comparators (risk ratio [RR] 1.05, 95% CI 0.95-1.16), but FCM was associated with a lower risk of gastrointestinal AEs compared to oral iron. Serious adverse events were rare and comparable across groups. Conclusion: Ferric carboxymaltose is effective and safe for treating IDA, offering a convenient single-dose option with a favorable safety profile. These findings support its use in clinical practice.
Adverse Drug Reactions Associated with COVID-19 Vaccination: A Systematic Review and Meta-Analysis
Background: The rapid development and deployment of COVID-19 vaccines have been crucial in controlling the pandemic. However, adverse drug reactions (ADRs) associated with these vaccines have raised concerns. This systematic review and meta-analysis aimed to comprehensively evaluate the incidence and types of ADRs following COVID-19 vaccination. Methods: We systematically searched PubMed, Embase, and Cochrane Library from inception to December 2024. Randomized controlled trials and observational studies reporting ADRs after COVID-19 vaccination were included. A random-effects model was used to pool incidence rates, and subgroup analyses were performed by vaccine type and dose. Results: A total of 45 studies with 1,234,567 participants were included. The overall incidence of any ADR was 62.3% (95% CI: 58.1-66.4%). Common local reactions included injection site pain (48.2%), swelling (22.5%), and redness (18.7%). Systemic reactions included fatigue (34.6%), headache (28.9%), and myalgia (22.3%). Serious ADRs were rare (0.02%). Subgroup analysis showed higher incidence with mRNA vaccines compared to viral vector vaccines. Conclusion: COVID-19 vaccines are associated with a high incidence of mild-to-moderate ADRs, but serious ADRs are extremely rare. These findings support the overall safety of COVID-19 vaccination programs.
