glycocholic acid/悪性腫瘍

The maximally tolerated dose (MTD) approach in conventional chemotherapy accompanies adverse effects, primarily due to high drug concentrations in the blood after intravenous administration and non-specific damages to highly proliferating cells, including immune cells. This causes the immune system

Rats with a total portacaval anastomosis (PCA, PC-SS) develop preneoplastic and neoplastic lesions in the urinary tract. In contrast to this, animals with a modified shunt (mPCA) do not develop these lesions. To evaluate the possible role of bile acids excreted with the urine for tumor development,

The proapoptotic effect of cisplatin bile acid derivatives Bamet-R2 [cis-diamminechloro-cholylglycinate-platinum(II)] and Bamet-UD2 [cis-diammine-bisursodeoxycholate-platinum(II)], developed to treat liver and intestinal tumors, was investigated in vitro using human enterohepatic cells HepG2

Cancer-cell resistance to chemotherapy limits the efficacy of cancer treatment. The primary mechanisms of multidrug resistance (MDR) are "pump" and "non-pump" resistance. We evaluated the effects and mechanisms of glycocholic acid (GC), a bile acid, on inhibiting pump and non-pump resistance, and

Nano-based drug delivery systems have been widely applied in cancer therapy, among that, particle sizes may affect the delivery efficiency of nanocarriers. The purpose of this study was to evaluate the potential impacts of particle size on tumor therapy, in consideration of this, lipid/glycocholic

The aim of this study was to use a two steps strategy metabolomics to screen/identify and validate novel metabolic biomarker(s) for epithelial ovarian cancer (EOC). In the screening step, serum samples from 27 healthy women, 28 benign ovarian tumors, and 29 EOCs were analyzed by using LC-MS based

Metabolomics is a post-genomics research field for analysis of low molecular weight compounds in biological samples and has shown great potentials for elucidating complex mechanisms associated with diseases. However, metabolomics studies on gastric cancer (GC), which is the second leading cause of

The aim of this study was to investigate the ability of the new liver organotropic complex of cisplatin with glycocholate (GC), Bamet-R2, to interact with DNA, inhibit its replication and hence reduce tumor-cell proliferation. Changes in the electrophoretic mobility of the open and covalently closed

Serum unconjugated primary bile acids (cholic acid, chenodeoxycholic acid), secondary bile acids (lithocholic acid, deoxycholic acid), conjugated primary bile acids (glycocholic acid, glycohenodeoxycholic acid, taurocholic acid, taurochenodeoxycholic acid) and total bile acids were measured in 25

BACKGROUND Regional chemotherapy by intraportal administration has been envisaged as a useful strategy to prevent the high rate of recurrence after surgical removal of single liver tumors, even though it may inhibit liver regeneration. New cytostatic drugs, such as

OBJECTIVE Several members of a novel family of bile acid derivatives with cytostatic and virostatic activity have been synthesized and characterized. The aim of this work was to investigate the liver organotropism and biotransformation of two novel compounds with enhanced DNA-reactivity: Bamet-D3,

Low water solubility and development of resistance are important drawbacks in the use of cisplatin as a cytostatic agent. A novel bile acid-cisplatin complex, Bamet-R2 [cis-diamminechlorocholylglycinateplatinum (II)], with liver vectoriality, has been synthesized. Our aim was to investigate the

Hepatocellular carcinoma (HCC) development entails changes in liver metabolism. Current knowledge on metabolic perturbations in HCC is derived mostly from case-control designs, with sparse information from prospective cohorts. Our objective was to apply comprehensive metabolite profiling to detect

Hepatocellular carcinoma (HCC) is the dominant histologic type of liver cancer, accounting for 75% of cases. Growing evidence suggests that the cross-talk between the gut microbiome and metabolome (i.e., gut-liver axis) are related to the development of hepatic inflammation, and ultimately, HCC.
