Coronary artery disease (CAD) poses a worldwide health threat. Compelling evidence shows that pericardial adipose tissue (PAT), a brown-like adipose adjacent to the external surface of the pericardium, is associated with CAD. However, the specific molecular mechanisms of PAT in CAD are elusive. This study aims to characterize human PAT and explore its association with CAD.

Association of Pericardiac Adipose Tissue With Coronary Artery Disease.

Serum uric acid (SUA) is suspected to be associated with atherosclerosis and calcium deposition in atherosclerosis is known to related poor prognosis, yet there is no cohort study on the aged in China. We aimed to investigate the relationships between SUA levels and coronary calcium deposition in the middle-aged and elderly populations in China.

Ascending aortic perivascular adipose tissue (AA-PVAT) mainly comprises brown adipose tissue (BAT), originates from neural crest cells that derive from ectoderm, and plays important role in angiotensin II-induced vascular inflammation and remodeling in mice. However, the characterization and function of human AA-PVAT remains highly unclear.

N-cadherin is considered a characteristic protein of EMT and has been found to be closely related to tumor resistance. In this study, a novel molecular imaging probe, Tc-HYNIC-ADH-1, was developed, and its diagnostic value in monitoring drug resistance in NSCLC was preliminarily investigated.

Development of Tc-Hynic-Adh-1 Molecular Probe Specifically Targeting N-Cadherin and Its Preliminary Experimental Study in Monitoring Drug Resistance of Non-Small-Cell Lung Cancer.

The cell adhesion molecule (CAM) N-cadherin has become an important target for tumor therapy. The N-cadherin antagonist, ADH-1, exerts significant antitumor activity against N-cadherin-expressing cancers.

Transforming growth factor β (TGF-β) is well known to play paradoxical roles in tumorigenesis as it has both growth-inhibitory and pro-metastatic effects. However, the underlying mechanisms of how TGF-β drives the opposing responses remain largely unknown. Here, we report that ERBB4, a member of the ERBB receptor tyrosine kinase family, specifically promotes TGF-β's metastatic response but not its anti-growth response. ERBB4 directly phosphorylates Tyr162 in the linker region of SMAD4, which enables SMAD4 to achieve a higher DNA-binding ability and potentiates TGF-β-induced gene transcription associated with epithelial-to-mesenchymal transition (EMT), cell migration, and invasion without affecting the genes involved in growth inhibition. These selective effects facilitate lung cancer metastasis in mouse models. This discovery sheds light on the previously unrecognized role of SMAD4 as a substrate of ERBB4 and highlights the selective involvement of the ERBB4-SMAD4 regulatory axis in tumor metastasis.

ERBB4 selectively amplifies TGF-β pro-metastatic responses.

Fatty acid metabolism plays a critical role in cancer development. In this study, a novel medium-chain fatty acid (MCFA) PET tracer, 2-[F]fluorohexanoic acid (F-FHA), was successfully synthesized with high radiochemical yield (65 ± 5.4%) and purity (>99%). Tumor radiotracer uptake at 60 min in A431, Hek293, Kpc, 4T1, Hep3b, and Lm3 xenograft models was 7.1 ± 0.4, 8.8 ± 0.6, 7.7 ± 0.5, 7.2 ± 0.4, 5.1 ± 0.3, and 4.9 ± 0.3 percentage injected dose per gram (% ID/g), respectively. Pretreatment with salicylic acid (SA), an inhibitor of medium-chain acyl-CoA synthetase (ACSM), significantly enhanced tumor uptake ( < 0.05) but showed no effect on blood uptake ( = 0.115). The biodistribution analysis demonstrated that F-FHA exhibited rapid hepatic and cardiac accumulation followed by gradual clearance, whereas tumor uptake exhibited gradual elevation within the initial 20 min and remained relatively stable through the 90 min observation period. F-FHA warranted further investigation as a potential PET imaging agent for tumors.
