Apoa1, short for apolipoprotein A1, is a member of the apolipoprotein family. It is the main protein moiety in high-density lipoprotein (HDL) particles and is crucial for reverse cholesterol transport (RCT). Apoa1 also has anti-inflammatory, anti-atherogenic, anti-apoptotic, and anti-thrombotic properties, endowing HDL particles with cardioprotective characteristics [1]. It is involved in multiple biological pathways related to lipid metabolism and cardiovascular health, and genetic models can be used to further explore its functions.

Apoa1 has been investigated in various disease states. In preeclampsia, its expression is elevated in plasma and placental tissues, and it affects trophoblast proliferation and invasion [2]. In kidney renal clear cell carcinoma, low levels of Apoa1 mRNA at surgery predict favorable survival, and preoperative serum Apoa1 protein is decreased in patients [3]. In squamous cervical cancer, overexpression of Apoa1 enhances resistance to platinum-based chemotherapy, and the mechanism may involve multiple regulatory pathways [4].

In conclusion, Apoa1 plays essential roles in lipid metabolism and cardiovascular protection. Model-based research, such as in cancer and pregnancy-related diseases, reveals its diverse functions. Understanding Apoa1's functions in these disease areas through gene knockout or conditional knockout mouse models (not specifically detailed in the given references but conceptually applicable) could potentially provide new strategies for disease prevention and treatment.
