glucuronic acid/유방암

The glucuronic acid level in the serum and urine, the diural excretion of estrogens and 17-KS with the urine, the activity of glucuronyltransferase are reported in 101 patients with benign and malignant tumors and in 22 healthy females. The decrease in the activity of glucurolytransferase and

BACKGROUND The latest experimental studies on human cancer diseases have observed the bioactive role of hyaluronic acid (HA) during carcinogenesis. HA is a component of the extra-cellular matrix (ECM). It is closely correlated with tumor cell growth, proliferation, and metastasis. The present study

Estrogens and androgens influence many properties of breast cancer cells; hence, regulation of local estrogen and androgen levels by enzymes involved in steroid hormone biosynthesis and metabolism would impact signaling by these hormones in breast cancer cells. In this study, we show that the

UDP-glucose dehydrogenase (UGDH) catalyzes two oxidations of UDP-glucose to yield UDP-glucuronic acid. Pathological over-production of extracellular matrix components may be linked to the availability of UDP-glucuronic acid, therefore UGDH is a potential therapeutic target. RNA interference (RNAi)

A dimeric 64-kDa lectin was purified from seeds of French bean (Phaseolus vulgaris) cultivar number 1. The purification protocol entailed Q-Sepharose, Affi-gel blue gel, Mono S and Superdex 75. The lectin-enriched fraction was adsorbed on Q-Sepharose and Affi-gel blue gel and desorbed using 1M NaCl

The phytoestrogen resveratrol has putative health-promoting effects and is present in several dietary constituents. Resveratrol is metabolized extensively in the gut epithelium, resulting in the formation of hydrophilic glucuronic acid and sulfate conjugates. These polar resveratrol conjugates need

Sanghuangporus is a traditional medicine that has been used for nearly 2000 years in Asia. It has been found to enhance immunity and have anticancer properties. Some studies determined that Sanghuangporus polysaccharide can inhibit tumors in vitro, although the underlying mechanisms remain unknown.

Dermatan sulfate (DS) is a glycosaminoglycan (GAG) that is produced through the epimerization of the glucuronic acid on chondroitin sulfate into iduronic acid (IduA) by dermatan sulfate epimerase (DS-epi) 1 and 2. Proteoglycans (PGs) play essential physiological and pathological roles during

Hyaluronic acid (hyaluronan, HA) is a critical component of the extracellular matrix and plays an important biological function of interacting with different molecules and receptors. In this study, both odd- and even-numbered HA oligosaccharides (HAOs) with specific degrees of polymerization (DP)

Tumor metastasis involves the dissemination of malignant cells into the basement membrane, and the vascular system contributes to the circulating pool of these markers. In this context, our aim has been focused on the development of a non-invasive score based on degradation of the backbone of

Increased uptake of glucose, a general hallmark of malignant tumors, leads to an accumulation of intermediate metabolites of glycolysis. We investigated whether the high supply of these intermediates promotes their flow into UDP-sugars, and consequently into hyaluronan, a tumor-promoting matrix

An improved understanding of the biochemical alterations that accompany tumor progression and metastasis is necessary to inform the next generation of diagnostic tools and targeted therapies. Metabolic reprogramming is known to occur during the epithelial-mesenchymal transition (EMT), a process that
