We examined the effects of GABA on type I collagen gene expression in normal human dermal fibroblasts. Real-time PCR analysis indicated GABA increased the level of type I collagen transcripts, and suppressed the expression of matrix metalloproteinase-1, which is a collagen-degrading enzyme. These results suggest GABA improves the skin elasticity by regulating type I collagen expression.

Insulin-like growth factor 2 (IGF2) is a mitogenic peptide hormone expressed by various tissues. Although it is three times more abundant in serum than IGF1, its physiological and pathological roles are yet to be fully understood. Previous transcriptome sequencing studies have shown that IGF2 expression is increased in hypertrophic scar (HS); however, its role in HS formation and the underlying mechanism remains elusive.

Heart failure with preserved ejection fraction (HFpEF) accounts for approximately 50% of heart failure cases globally, and this incidence is increasing due to extended lifespans and accumulating comorbidities. Emerging evidence suggests that Wnt signaling plays a role in cardiomyocyte hypertrophy and cardiac fibrosis, which are key features of HFpEF. Furthermore, Porcupine (PORCN) inhibitors, which negatively regulate Wnt signaling, have shown promising results in improving cardiac function and reducing cardiac hypertrophy and/or fibrosis.

Sonodynamic therapy is an emerging therapeutic approach for combating bacterial infections. However, the characteristics of hypoxia, high HO microenvironment, and the formation of persistent biofilms in diabetic wound sites limit its efficacy in this field. To address these issues, we developed a multifunctional antibacterial hydrogel dressing PPCN@Pt-AMPs/HGel with the cross-linked gelatin and sodium alginate as the matrix, where the nanosonosensitizer PCN-224 was decorated with the oxygen-generating Pt nanoenzyme and further coupled with a biofilm-targeting antimicrobial peptide via an interacting polydopamine layer.

Background And Aims: Cerebral small vessel diseases (CSVDs) are a set of conditions that affect the small blood vessels in the brain and can cause severe neurological pathologies such as stroke and vascular dementia. The most common monogenic CSVD is cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) which is caused by mutations in NOTCH3. However, only 15-20% of CADASIL cases referred for genetic testing have pathogenic mutations in NOTCH3.
