On the regulatory role of side-chain hydroxylated oxysterols in the brain. Lessons from CYP27A1 transgenic and Cyp27a1−/− mice1 [PDF]
The two oxysterols, 27-hydroxycholesterol (27OH) and 24S-hydroxycholesterol (24OH), are both inhibitors of cholesterol synthesis and activators of the liver X receptor (LXR) in vitro.

Tissue specific role of ABCA1 in lung cholesterol homeostasis under high-cholesterol diet [PDF]
BackgroundATP-binding cassette subfamily A1 (ABCA1) and sterol 27-hydroxylase (CYP27A1) are essential regulators of cholesterol metabolism. However, their tissue-specific roles, particularly in the lung, under high-cholesterol diet (HCD) conditions ...

Integrative multi-omics and machine learning reveals the spatial niche distribution and role of CYP27A1+TAMs in immunotherapy response in non-small cell lung cancer [PDF]
BackgroundThe response rate to immune checkpoint blockade (ICB) in non-small cell lung cancer (NSCLC) varies significantly among individuals. Cancer-associated macrophages (TAMs) are key components of the tumor immune microenvironment (TIME), influencing
