Proteomics Reveals Mechanisms of Delayed Keratoconus Progression: A Study of Corneas Following Two Light-Activated Crosslinking Treatments.

University Eye Clinic Maastricht, Maastricht University Medical Center, Maastricht, the Netherlands.
Article Synopsis
- This study investigates the biological changes in rabbit corneas caused by two light-activated corneal stiffening methods: riboflavin with UVA and WST11 with NIR.
- Differentially expressed proteins were identified following treatments, showing RF-D/UVA affected cell metabolism and keratocyte differentiation, while WST-D/NIR influenced extracellular matrix regulation.
- The findings reveal a metabolic shift towards glycolysis in RF-D/UVA treated corneas compared to normal respiration in WST-D/NIR treated corneas, highlighting the distinct biological effects of each treatment.
SP-1-activated LINC01016 overexpression promotes gastric cancer invasion and metastasis through inhibiting EIF4A3-mediated MMP9 mRNA decay.

Long noncoding RNAs (lncRNAs) are key regulators during gastric cancer (GC) development and may be viable treatment targets. In the present study, we showed that the expression of the long intergenic noncoding RNA 01016 (LINC01016) is significantly higher in GC tissues with lymph node metastasis (LNM) than those without LNM. LINC01016 overexpression predicts a poorer relapse-free survival (RFS) and overall survival (OS).

Although DNA methyltransferase 1 (DNMT1) and RNA editor ADAR triplications exist in Down syndrome (DS), their specific roles remain unclear. DNMT methylates DNA, yielding S-adenosine homocysteine (SAH), subsequently converted to homocysteine (Hcy) and adenosine by S-adenosine homocysteine (Hcy) hydrolase (SAHH). ADAR converts adenosine to inosine and uric acid.

Department of Biochemistry and Molecular Cell Biology, Shanghai Jiao Tong University School of Medicine, Shanghai, China. Electronic address:
The glomerular filtration barrier (GFB) has a unique spatial structure, including porous capillary endothelial cells, glomerular basal membrane (GBM) and highly specialized podocytes. This special structure is essential for the hemofiltration process of nephrons. GBM is the central meshwork structure of GFB formed by the assembly and fusion of various extracellular matrix (ECM) macromolecules, such as laminins and collagens, which undergo isoform transformation and maturation that may require precise regulation by metalloproteinases.

Matrix metalloproteinases (MMP) have been identified as biomarkers for several diseases, including cancer. The increase in the expression of these enzymes has been related to greater tumor aggressiveness. MMP-26 is expressed constitutively in the endometrium and some cancer cells of epithelial origin.
