Sorting Nexin 10 Mediates Metabolic Reprogramming of Macrophages in Atherosclerosis Through the Lyn-Dependent TFEB Signaling Pathway.

Rationale: SNX10 (sorting nexin 10) has been reported to play a critical role in regulating macrophage function and lipid metabolism.

Objective: To investigate the precise role of SNX10 in atherosclerotic diseases and the underlying mechanisms.

Methods And Results: SNX10 expression was compared between human healthy vessels and carotid atherosclerotic plaques.

NADPH oxidase 4 contributes to connective tissue growth factor expression through Smad3-dependent signaling pathway.

Transforming growth factor-β (TGF-β)/Smad signaling has been implicated in connective tissue growth factor (CTGF) expression in vascular smooth muscle cells (VSMC). Reactive oxygen species (ROS) are involved in activation of TGF-β/Smad signaling. However, detailed mechanisms underlying the process remain unclear.

Overexpression of interleukin-1β and interferon-γ in type I thoracic aortic dissections and ascending thoracic aortic aneurysms: possible correlation with matrix metalloproteinase-9 expression and apoptosis of aortic media cells.

Objective: To examine the expression of interleukin-1β and interferon-γ and their possible roles in aortic dissections and aneurysms.

Methods: Aortic specimens were obtained from patients with type I thoracic aortic dissection, ascending thoracic aortic aneurysms, and control organ donors. The expression of interleukin-1β, interferon-γ, matrix metalloproteinase-9, and signal transduction factors phospho-p38 and phosphorylated c-jun N-terminal kinase (phospho-JNK) were detected by real time reverse transcription-polymerase chain reaction (real time RT-PCR), Western blot, and immunohistochemistry, respectively.
