Summary: Chondroitin sulphate (CS) proteoglycans, which are closely associated with the stem cell niche of articular cartilage, were found to be present in the subepithelial corneal stroma and nearby ossicles in the adult chicken cornea. When cultivated on CS/dermatan sulphate (DS)-coated dishes, corneal stromal cells exhibited a less-differentiated phenotype and expressed stem cell markers. These findings suggest that CS/DS may play a role in maintaining a stem cell phenotype in corneal cells.

Summary: Systemic sclerosis (SSc) is a chronic connective tissue disease characterized by immune system dysfunction, vasculopathy, and progressive fibrosis. This study aimed to quantify different types of glycosaminoglycans (GAGs) in the blood and urine of SSc patients. The study found elevated levels of GAGs in plasma and urine of SSc patients compared to healthy subjects, indicating their potential as markers for disease progression and early renal dysfunction diagnosis.

Summary: Chondroitin sulfate proteoglycans are a type of proteoglycan found on cell surfaces and in connective tissues, interacting with proteins involved in various pathophysiological processes. Recent advances in glycoproteomic methods have allowed for the identification of numerous novel chondroitin sulfate core proteins and attachment sites in humans and animal models, revealing greater structural complexity of CSPGs than previously perceived. These findings may challenge traditional notions of defining proteoglycans based on function or structural evidence.

Summary: Extraesophageal reflux symptoms are common in the Western population and their clinical management is controversial. This study evaluated a new treatment method for patients with GERD experiencing extraesophageal symptoms. The results showed that the treatment method reduced symptom frequency and severity.

Summary: Glycosaminoglycans (GAGs) are long polysaccharides found on the cell surface and extracellular matrix of animal cells, and play important roles in cellular processes and diseases. GAGs are complex molecules with extensive structural and functional heterogeneity, and their biosynthesis is a non-template driven process involving a group of enzymes. Due to their key roles in cell homeostasis and disease, targeting the assembly and function of GAGs is of great interest as a therapeutic approach.

Summary: This study investigated the changes in glycosaminoglycans (GAGs) composition and metabolism in the brain during neuroinflammation using a mouse model. The results showed that there were alterations in GAG metabolism during early stages of experimental autoimmune encephalomyelitis (EAE), and these changes may contribute to the progression of inflammatory disorders like multiple sclerosis (MS).

Summary: This study analyzed the pattern of urinary excretion of total sulphated glycosaminoglycans (GAGs) and their particular types in obese patients with type 2 diabetes mellitus (T2DM) treated with metformin. The results showed that metformin therapy for six months significantly decreased the urinary excretion of total GAGs, CS/DS, and HS.

Summary: This study discovered that pteropine orthoreoviruses (PRVs) may use heparan sulphate (HS), a receptor widely expressed in all cell types, as an attachment receptor for entering host cells due to its broad tissue tropism. The hypothesis was supported by experiments on multiple genetically distinct PRV species. Moreover, it was found that HS plays a crucial role in the early phase of PRV infection.

Summary: Chondroitin sulfate (CS) with different molecular weights was tested using uronic acid carbazole assay and cetylpyridinium chloride (CPC) titration, showing that the measurement values decrease with the increase of CS molecular weight. It is important to know the molecular weight values and use comparable standards before applying the assays to obtain reliable results.

Summary: Diabetes mellitus leads to metabolic derangements and organ damage, partially due to glycosaminoglycan (GAG) damage in the basement membrane. GAGs are polysaccharides with repeating disaccharide units and play a significant role in cellular processes. The destruction of extracellular matrix can result in various diseases in organs. GAG-based therapeutic agents are being evaluated for managing diabetic complications.

Summary: Heparan sulfate (HS) plays a crucial role in cancer development, impacting various aspects such as proliferation, angiogenesis, and metastasis. Due to its interaction with different ligands, HS has pleiotropic effects on important cellular receptors and downstream signaling pathways. Aberrant expression of HS can determine malignant features of tumors.

Summary: The development and application of AI algorithms are of great significance for the removal of cSCC, as they can improve operational efficiency and accuracy, especially for moderately and poorly differentiated tumors/ neoplasms. Further improvement is needed to maintain sensitivity to surrounding tissue and determine anatomical positioning.

Summary: This study investigated the role and mechanisms of NTS in stress-induced hair growth inhibition. The results demonstrated that NTS effectively counteracted hair growth inhibition caused by stress and regulated the expression of multiple genes related to hair growth at the transcriptional level.
