Proteomic analysis of cerebrospinal fluid (CSF) from patients with temporal lobe epilepsy (TLE) and controls was carried out using two-dimensional gel electrophoresis followed by liquid chromatography electrospray ionization tandem mass spectrometry. Five protein spots showed significant differential expression (p<0.05): vitamin D-binding protein (DBP) was elevated in the CSF of TLE patients whereas cathepsin D, apolipoprotein J, Fam3c, and superoxide dismutase 1 (SOD1) were decreased in the CSF of TLE patients. Additional six protein spots presented only in the CSF of epilepsy patients were identified as tetranectin (TN), talin-2, apolipoprotein E, immunoglobulin lambda light chain (IGL@), immunoglobulin kappa variable light chain 1-5 (IGKV1-5), and procollagen C-endopeptidase enhancer 1 (PCOLCE). Expression of DBP, SOD1 and talin-2 was validated by western blot. Our results may provide better understanding of the pathophysiologic mechanisms underlying epileptogenesis and possible epilepsy biomarkers.

Background: This research aims to explore the anti-obesity potential of Wu-Mei-Wan (WMW), particularly its effects on adipose tissue regulation in obese mice induced by a high-fat diet (HFD). The study focuses on understanding the role of heat shock factor 1 (HSF1) in mediating these effects.
Methods: HFD-induced obese mice were treated with WMW.

Our objective is to determine the protein and complements constituents of Cord blood Platelet-rich plasma (CB-PRP), based on the hypothesis that it contains beneficial components capable of arresting or potentially decelerating the advancement of atrophic age-related macular degeneration (dry-AMD), with the support of radiomics. Two distinct pools of CB-PRP were assessed, each pool obtained from a total of 15 umbilical cord-blood donors. One aliquot of each pool respectively was subjected to proteomic analysis in order to enhance the significance of our findings, by identifying proteins that are shared between the two sample pools and gaining insights into the pathways they are associated with.

Hepatocellular carcinoma (HCC) necessitates innovative prognostic biomarkers and therapeutic targets. By investigating PNMA1 in HCC via the TCGA and GEO databases and our clinical data, we found that its overexpression is associated with worse survival. The relevance of PNMA1 extends to immune factors such as M1 macrophages, CD8 T cells, and immune checkpoints.

Obesity and type 2 diabetes are prevalent chronic diseases effectively managed by semaglutide. Here we studied the effects of semaglutide on the circulating proteome using baseline and end-of-treatment serum samples from two phase 3 trials in participants with overweight or obesity, with or without diabetes: STEP 1 (n = 1,311) and STEP 2 (n = 645). We identified evidence supporting broad effects of semaglutide, implicating processes related to body weight regulation, glycemic control, lipid metabolism and inflammatory pathways.

Background: Epilepsy has a genetic predisposition, yet causal factors and the dynamics of the immune environment in epilepsy are not fully understood.
Methods: We analyzed peripheral blood samples from epilepsy patients, identifying key genes associated with epilepsy risk through Mendelian randomization, using eQTLGen and genome-wide association studies. The peripheral immune environment's composition in epilepsy was explored using CIBERSORT.
