Functional Roles Of The Complement Immune System In Cardiac Inflammation And Hypertrophy, Kathryn D Hok, Haydn E Rich, Anthony Shadid, Lavanya Gunamalai, Tingting Weng-Mills, Rajarajan A Thandavarayan, Nirmal K Banda, Marie-Francoise Doursout, Marcos I Restrepo, Pooja Shivshankar

The Brown Foundation: Institute of Molecular Medicine

Cardiac inflammation and hypertrophy develop as a pathologic response to an array of insults, such as myocardial infarctions, chronic systemic hypertension, and valvular defects. Due to the high prevalence of such conditions, there is an increasing need to prevent and halt cardiac hypertrophy. Because cardiac damage and subsequent remodeling can lead to arrhythmias, heart failure, and even sudden cardiac death, inhibition of cardiac hypertrophy is key to reducing cardiovascular-related mortality. The immune system is the driving force behind inflammatory reactions. All three pathways of complement system activation-classical, lectin, and alternative-are implicated in developing cardiac damage, inflammation, and hypertrophy due to …

Genetic Engineering Of Esophageal Organoids: Crispr-Based Knock-In For Cell Lineage Tracing, Kyung-Pil Ko, Jae-Il Park

Faculty, Staff and Student Publications

Esophageal organoids serve as powerful systems to study epithelial lineage hierarchies and cancer biology. Gene manipulation in these organoids has traditionally involved overexpression or knockout strategies. However, CRISPR-/Cas9-based knock-in (KI) approaches now enable precise cell lineage tracing and live imaging. Here, we describe protocols to generate fluorescent KI organoids from murine esophageal epithelium by tagging Krt13 (BFP) and Sox2 (mNeon). These dual-reporter organoids allow direct monitoring of growth dynamics and differentiation trajectories. We outline CRISPR/Cas9 design, donor construction using homology-independent approaches (CRISPaint), delivery into organoid cells, enrichment and single-clone isolation, and validation by fluorescence. For organoids, homology-directed repair (HDR) can …
