Fucosylated chondroitin sulfate (FucCS) is structurally distinct glycosaminoglycans found from the sea cucumber body wall consisted of chondroitin sulfate type backbone with attached sulfated or non-sulfated fucose side chain. Structurally this compound plays an important role in maintaining the body wall integrity and possesses a wide spectrum of biological activities. Recently several glycosaminoglycans' structures have been solved to elucidate its physicochemical activity. The purpose of this review paper is to elaborate existing structural properties and functions, reporting over 30 years and systematically discussion herein.

Hepatocellular carcinoma (HCC) is a major public health threat due to its high incidence and mortality rates. Transcatheter arterial chemoembolization (TACE), the primary treatment for intermediate-to-advanced hepatocellular carcinoma (HCC), commonly utilizes embolic agents loaded with anthracycline-based cytotoxic drugs. Post-TACE, the hypoxic microenvironment in the tumor induced by embolization stimulates the formation of new blood vessels, potentially leading to revascularization and diminishing TACE's efficacy.

The high-dynamic, high-loading environment in the joint cavity puts urgent demands on the cartilage regenerative materials with shear responsiveness and lubrication. Here, a new type of injectable hydrogel composed of oxidized hyaluronic acid (OHA), adipic dihydrazide-grafted hyaluronic acid (HA-ADH), oxidized chondroitin sulfate (OChs), and decellularized extracellular matrix methacrylate (dECMMA) was fabricated. The aldehyde groups in OHA and OChs reacted with the amino groups in HA-ADH to form a dynamic hydrogel, which was then covalently crosslinked with dECMMA to create a dual-crosslinked hydrogel with sufficient mechanical strength.

Nanomedicine-driven ferroptosis has emerged as a promising tumor treatment strategy through delivering exogenous iron and aggravating the lethal accumulation of lipid peroxides (LPO). However, the compensatory mechanisms of ferroptosis defense systems in cancer cells compromise the therapeutic efficacy and lead to potential side effects. Herein, a highly effective ferroptotic nano-amplifier is designed to synergistically promote ferroptosis via increasing intracellular labile iron, exacerbating lipid peroxidation and overcoming the defense system.

Glycosaminoglycans (GAGs) play a pivotal role in pathogen attachment and entry into host cells, where the interaction with GAGs is critical for a diverse range of bacteria and viruses. This study focuses on elucidating the specific interactions between sulfated GAGs and the adhesin OmcB (Outer membrane complex protein B) of Chlamydia species, examining how structural characteristics of GAGs, such as sulfation degree and molecular weight, influence their binding affinity and thereby affect bacterial infectivity. A surface-based binding assay is established to determine the binding constants of OmcB with various GAGs.

Cadmium is a heavy metal risk factor for various cardiovascular diseases, such as atherosclerosis. In atherosclerotic lesions, hyaluronan, a glycosaminoglycan consisting of β4-glucuronic acid-β3-N-acetylglucosamine disaccharides repeats, is highly accumulated, regulating signal transduction, cell migration, and angiogenesis. Hyaluronan is synthesized by hyaluronan synthase (HAS)1-3 in the plasma membrane and secreted into the extracellular space.
