ACSL1 Aggravates Thromboinflammation by LPC/LPA Metabolic Axis in Hyperlipidemia Associated Myocardial Ischemia-Reperfusion Injury.

Acute myocardial infarction (AMI) is associated with well-established metabolic risk factors, especially hyperlipidemia and obesity. Myocardial ischemia-reperfusion injury (mIRI) significantly offsets the therapeutic efficacy of revascularization. Previous studies indicated that disrupted lipid homeostasis can lead to lipid peroxidation damage and inflammation, yet the underlying mechanisms remain unclear.

The Buerger's rabbit model: a closer step to unravelling thromboangiitis obliterans?

Objective: Thromboangiitis obliterans (TAO) remains clinical challenging due to its rarity and underwhelming management outcomes. This study aimed to describe a novel TAO rabbit model that demonstrates a closer resemblance to TAO.

Methods: Thirty-six New Zealand rabbits underwent the surgical implantation of calibrated gelatin sponge particles (CGSPs) into their right femoral artery.

Differential expression profile of miRNAs between stable and vulnerable plaques of carotid artery stenosis patients.

Plaque vulnerability is associated with the degree of carotid artery stenosis (CS) and the risk of stroke. MicroRNAs (miRNAs) exert critical functions in disease progression, although only a few miRNAs have been well identified in CS. Therefore, this study aimed to investigate the differential expression profile of miRNAs and their potential functions in plaques of CS patients.

RNA Sequencing Reveals the Differentially Expressed circRNAs between Stable and Unstable Carotid Atherosclerotic Plaques.

Objective: This study aimed to identify circular RNA profiles (circRNAs) via high-throughput RNA sequencing and distinguish the differentially expressed (DE) circRNAs between stable and unstable plaques.

Methods: RNA sequencing was performed on unstable and stable carotid plaque samples obtained from patients with carotid artery stenosis. DE circRNAs were screened, and six DE circRNAs were verified using quantitative real-time PCR (qRT-PCR).

Cancer-associated fibroblasts support bone tropic metastasis by acting as coordinators between the tumor microenvironment and bone matrix in breast cancer.

Bone is a common site of metastasis for various types of cancer cells, including breast cancer, and the consequent skeleton-related events observed in patients are severe and often fatal. Currently, it is widely accepted that cancer-associated fibroblasts (CAFs) confer a metastasis-promoting property to breast cancer cells. Furthermore, clinical observations suggest that CAFs mediate the bone tropism of metastatic breast cancer cells.
