Non-viral gene delivery systems have gained significant attention as safer alternatives to viral vectors for lung cancer transfection. These methods utilize synthetic or natural materials to transport nucleic acids into cells, minimizing immunogenicity, insertional mutagenesis, and manufacturing complexities associated with viral vectors. Lipid-based nanoparticles remain the most extensively studied non-viral carriers, offering tunable properties for…

Primary lung cancer cells isolated directly from patient tumors offer the most physiologically relevant model for studying cancer biology and testing therapeutics. However, transfecting these cells presents unique challenges compared to established cell lines due to their heterogeneity, limited proliferation, and increased sensitivity to stress. Primary lung cancer cells often exhibit low transfection efficiency and…

Exosomes are small extracellular vesicles secreted by cells that mediate intercellular communication by transferring proteins, lipids, and nucleic acids, including RNA and DNA. In lung cancer research, exosome-mediated gene transfer is an emerging area with significant implications for tumor progression, metastasis, and therapeutic delivery. Exosomes derived from lung cancer cells can transfer oncogenic miRNAs or…

MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression post-transcriptionally, playing critical roles in lung cancer development, progression, and drug resistance. Transfection of synthetic miRNA mimics or inhibitors into lung cancer cells enables researchers to investigate their functional roles and therapeutic potential. Effective delivery of miRNAs into lung cancer cell lines such as A549,…

Viral vectors are powerful tools for gene delivery in lung cancer research due to their high transduction efficiency and ability to mediate stable gene expression. Commonly used viral systems include adenoviruses, lentiviruses, and adeno-associated viruses (AAV), each offering distinct advantages for different experimental needs. Adenoviral vectors provide high transgene expression levels and are often employed…

Lipid nanoparticles (LNPs) have emerged as a leading non-viral delivery platform for mRNA therapeutics, offering a promising approach for lung cancer research and therapy. LNPs encapsulate mRNA molecules, protecting them from degradation and facilitating cellular uptake, thereby enabling efficient transient expression of therapeutic proteins or gene-editing components in lung cancer cells. In lung cancer models,…

Electroporation is a widely used physical transfection method that employs short electrical pulses to temporarily permeabilize cell membranes, allowing nucleic acids to enter lung cancer cells. Achieving high transfection efficiency with minimal cytotoxicity requires careful optimization of electroporation parameters tailored to specific lung cancer cell lines. Key parameters include voltage amplitude, pulse duration, number of…

Lung cancer organoid models have emerged as advanced three-dimensional (3D) culture systems that more accurately replicate the architecture and cellular diversity of tumors compared to traditional two-dimensional cell lines. These miniaturized, patient-derived organoids maintain critical features of the original lung tumor, including genetic heterogeneity and microenvironmental interactions, making them powerful tools for studying gene function…

CRISPR/Cas9 technology has revolutionized the study of lung cancer biology by enabling precise genome editing to investigate gene function, identify therapeutic targets, and develop novel treatment strategies. This powerful tool allows researchers to introduce targeted mutations, deletions, or insertions within the genome of lung cancer cells, thereby modeling oncogenic events or reversing pathological gene expression….

The tumor microenvironment (TME) in lung cancer poses significant challenges for effective transfection and gene delivery. Composed of extracellular matrix components, stromal cells, immune infiltrates, and vascular networks, the TME influences the uptake, distribution, and efficacy of nucleic acid therapeutics. Understanding and overcoming these barriers are essential for advancing lung cancer gene therapy and functional…
