The discovery of APOA1, a pivotal protein component of high-density lipoprotein (HDL), dates back to 1975, when seminal research on human plasma lipoproteins provided insights into its role. Also recognized as apolipoprotein A-I, APOA1 plays a critical function in lipid metabolism and transport, particularly within the reverse cholesterol transport pathway. Its significance lies in facilitating the removal of surplus cholesterol from peripheral tissues and its transportation to the liver for elimination. Unveiling APOA1's presence opened avenues for further exploration into its physiological functions and potential implications in cardiovascular health and pathology.
Concurrently, the establishment of a stable cell line expressing human APOA1 represented a significant advancement in biomedical inquiry. Achieved through meticulous molecular biology methodologies, this cell line serves as a valuable resource for delving into the functional roles of APOA1 in cellular and molecular mechanisms. Derived from Chinese hamster ovary cells, CHO-K1 cells possess robust growth characteristics and are amenable to genetic manipulation, rendering them an optimal platform for stable expression of human APOA1. These cell lines have played a crucial role in advancing our understanding of APOA1 biology and exploring its potential therapeutic applications in managing cardiovascular conditions.
To explore how apolipoprotein A1 (APOA1) boosts the resistance of cervical squamous carcinoma to platinum-based chemotherapy. Researchers investigated the role of APOA1 in platinum-based chemotherapy resistance in cervical cancer. Overexpression of APOA1 reduced clone-forming ability after carboplatin treatment compared to controls. Tandem Mass Tag analysis identified 64 differentially expressed proteins downstream of APOA1. Gene Ontology analysis revealed involvement in pathways like p38 MAPK signaling via STAT1, PI3K signaling via CD81 and C3, and platinum-based chemoresistance via TOP2A.
