The development of high-efficiency methods for the introduction of functional genetic material into eukaryotic cells using cationic lipids has accelerated biological research in the studies of gene expression, control of cell growth, and cell lineage. Transfection mediated by cationic lipids is commonly used in industrial protein production as well as in some clinical gene therapy protocols. Replacing our previous unit on this topic, this new version describes how to perform transfection of adherent and suspension cells, insect cells, and RNA transfection using the cationic lipid system.

Invasive fungal infections cause over 3.7 million deaths worldwide annually, underscoring the critical need for new antifungal agents. Developing selective antifungal agents is challenging due to the shared eukaryotic nature of both fungal and mammalian cells.

Spontaneous tumor regression is a recognized phenomenon across various cancer types. Recent research emphasizes the alterations in autoantibodies against carbonic anhydrase I (CA I) (anti-CA I) levels as potential prognostic markers for various malignancies. Particularly, autoantibodies targeting CA I and II appear to induce cellular damage by inhibiting their respective protein's catalytic functions.

They are difficult to study, as interfering with their function leads to premature death. Transcription is one of the essential functions of life, and the multi-protein Mediator complex coordinates the regulation of gene expression at nearly every eukaryotic promoter.

The strength and speed of ISR activation must be tuned properly to allow protein synthesis while maintaining proteostasis. Here, we describe how genetic perturbations change the dynamics of the ISR in budding yeast.

Deoxyhypusine synthase (DHPS) is an enzyme encoded by the DHPS gene, with high expression in various cancers, including ovarian cancer (OC). DHPS regulates the translation initiation factor EIF5A, and EIF5A2 knockout inhibits OC tumor growth and metastasis by blocking the epithelial-to-mesenchymal transition (EMT) and the TGFβ pathway. In this study, we show that DHPS is amplified in OC patients, and its elevated expression correlates with poor survival.
