Obesity is an independent risk factor for the development of chronic kidney disease. The pathophysiology of the obesity-induced kidney injury is complex, but evidence suggests the involvement of reduced adiponectin levels and signaling. We investigated the extent by which adiponectin contributes to the establishment and progression of renal disease in wild type (WT) and adiponectin null (adipoKO) mice fed a control or a high-fat diet (HFD) for 16 weeks. HFD induced obesity, kidney hypertrophy, albuminuria, renal lipid accumulation and decreased nephrin expression in both mice genotypes. Notably, HFD in adipoKO mice exacerbated progression of albuminuria in comparison to WT mice. In addition, lack of adiponectin per se increased kidney weight, reduced nephrin levels, up-regulated Fabp4 expression, reduced Cpt1a expression and increased miR-130 levels in kidney. Our results demonstrate that lack of adiponectin combined with a HFD contributes to accelerated kidney dysfunction.

T-cadherin modulates adipogenic differentiation in mesenchymal stem cells: insights into ligand interactions.

Introduction: T-cadherin, a non-canonical member of the cadherin superfamily, was initially identified for its involvement in homophilic recognition within the nervous and vascular systems. Apart from its adhesive function, T-cadherin acts as a receptor for two ligands: LDL, contributing to atherogenic processes, and HMW adiponectin, a hormone with well-known cardiovascular protective properties. However, the precise role of T-cadherin in adipose tissue remains elusive.

Glioblastoma (GB) is the most prevalent and aggressive primary brain tumor with fatal outcome due to a lack of effective treatments. We previously identified C1q-tumor necrosis factor-related protein 8 (CTRP8), a new member of the adiponectin family, as a novel agonist of the relaxin family peptide receptor 1 (RXFP1) and showed that the CTRP8-RXFP1 ligand-receptor system facilitates increased invasiveness and chemoresistance in GB cells. In the present study, we have investigated the role of the CTRP8-RXFP1 signaling axis in glioma progression using an orthotopic mouse model xenografted with human U251 glioma cells stably expressing CTRP8 and RXFP1.

Background: Atopic dermatitis and diabetes mellitus are chronic, immune-mediated, inflammatory diseases that significantly affect patients' quality of life and also represent a considerable socioeconomic burden. Despite intensive research in recent decades, the possible link between these two medical conditions remains a controversial topic due to sparse and sometimes contradictory data. Nevertheless, the potential link between them is based on some recognized common pathophysiological features.

<b>Indroduction:</b> Cryptoglandular perianal fistula represents a prevalent benign anorectal condition, primarily addressed through surgical interventions, occasionally posing considerable therapeutic challenges. The associated decline in patient quality of life underscores the significance of effective management. However, the lack of a fully understood pathogenesis complicates the treatment approach.

Pentraxin 3 (PTX3) is a prototypic humoral soluble pattern-recognition molecule known to function in immunity-related inflammation. Given the lack of information on the precise functions of PTX3 in the pathogenesis of Graves' orbitopathy (GO), this study investigated the role of PTX3 in the inflammation and adipogenesis mechanisms of GO. We first compared the PTX3 expression between orbital tissues from patients with GO and normal controls using real-time PCR, which estimated significantly higher PTX3 transcript levels in the GO tissues than in the normal tissues.
