This study sought to determine whether eAVM-MCs could induce endothelial-to-mesenchymal transition (EndMT), a process known to disrupt vascular integrity, in the eAVM microenvironment. eAVM and paired control tissues were analyzed using RT-PCR for EC (, , and ) and EndMT-specific markers (, , , /.

CircRNA-loaded DC vaccine in combination with low-dose gemcitabine induced potent anti-tumor immunity in pancreatic cancer model.

Although promising, dendritic cell (DC) vaccines may not suffice to fully inhibit tumor progression alone, mainly due to the short expression time of the antigen in DC vaccines, immunosuppressive tumor microenvironment, and tumor antigenic modulation. Overcoming the limitations of DC vaccines is expected to further enhance their anti-tumor effects. In this study, we constructed a circRNA-loaded DC vaccine utilizing the inherent stability of circular RNA to enhance the expression level and duration of the antigen within the DC vaccine.

However, the mechanism underlying necroptosis in IDD remains unclear.

Lentivirus-mediated Knockdown of Ski Improves Neurological Function After Spinal Cord Injury in Rats.

The glial scar that forms at the site of injury after spinal cord injury (SCI) is an important physical and biochemical barrier that prevents axonal regeneration and thus delays functional recovery. Ski is a multifunctional transcriptional co-regulator that is involved in a wide range of physiological and pathological processes in humans. Previous studies by our group found that Ski is significantly upregulated in the spinal cord after in vivo injury and in astrocytes after in vitro activation, suggesting that Ski may be a novel molecule regulating astrocyte activation after spinal cord injury.

Flt3 ligand augments immune responses to soluble PD1-based DNA vaccine via expansion of type 1 conventional DCs.

DNA vaccines are prospective for their efficient manufacturing process, but their immunogenicity is limited as they cannot efficiently induce CD8 T cell responses. A promising approach is to induce cross-presentation by targeting antigens to DCs. Flt3L can expand the number of type 1 conventional DCs and thereby improve cross-presentation.

Knocking down EGR1 inhibits nucleus pulposus cell senescence and mitochondrial damage through activation of PINK1-Parkin dependent mitophagy, thereby delaying intervertebral disc degeneration.

Mitophagy plays a crucial role in maintaining the homeostasis of intervertebral disc (IVD). Early Growth Response 1 (EGR1), a conservative transcription factor, is commonly upregulated under oxidative stress conditions and participates in regulating cellular senescence, apoptosis, and inflammatory responses. However, the specific role of EGR1 in nucleus pulposus (NP) cell senescence and mitophagy remains unclear.

Quantitative plasma proteomic analysis in children after superior cavopulmonary anastomosis with pulmonary arteriovenous malformations.

Approximately 1000 children are born every year in the United States with one effective cardiac pumping chamber, or single ventricle heart disease. One of the early causes of mortality in this population is pulmonary arteriovenous malformations (PAVMs), which allow blood to bypass gas exchange in the lungs. PAVMs most frequently occur in children after superior cavopulmonary anastomosis (SCPA), a procedure that redirects venous blood from the upper body to the lungs.
