The effects of buthionine sulfoximine on the proliferation and apoptosis of biliary tract cancer cells induced by cisplatin and gemcitabine.

Oncology letters

Li Q, Yin X, Wang W, Zhan M, Zhao B, Hou Z, Wang J.
PMID: 26870236
Oncol Lett. 2016 Jan;11(1):474-480. doi: 10.3892/ol.2015.3879. Epub 2015 Nov 06.

Patients with biliary tract cancer (BTC) have a poor prognosis. Advanced BTC patients have been treated with cisplatin in combination with gemcitabine, however, the treatment has had little impact on survival rates, and more effective treatments are urgently required...

BACKGROUND: Crocin is an active ingredient of saffron (Crocus sativus L.) and its antioxidant properties have been previously investigated. This carotenoid scavenges free radicals and stimulates glutathione (GSH) synthesis; consequently, it may protect cells against oxidative stress. The aim...

Cellular glutathione content in the organ of Corti and its role during ototoxicity.

Glutathione (GSH) is the major scavenger of reactive oxygen species (ROS) inside cells. We used live confocal imaging in order to clarify the role of GSH in the biology of the organ of Corti, the sensory epithelium of the...

Demand-Driven Control of Root ATP Sulfurylase Activity and SO42- Uptake in Intact Canola (The Role of Phloem-Translocated Glutathione).

Plant physiology

Lappartient AG, Touraine B.
PMID: 12226281
Plant Physiol. 1996 May;111(1):147-157. doi: 10.1104/pp.111.1.147.

The activity of ATP sulfurylase extracted from roots of intact canola (Brassica napus L. cv Drakkar) increased after withdrawal of the S source from the nutrient solution and declined after refeeding SO42- to S-starved plants. The rate of SO42-...

Signalling steps in apoptosis by ether lipids.

Apoptosis : an international journal on programmed cell death

Smets LA, Van Rooij H, Salomons GS.
PMID: 14634326
Apoptosis. 1999 Dec;4(6):419-27. doi: 10.1023/a:1009644208512.

We have investigated the mechanisms of induction of apoptosis by the antineoplastic ether lipid ET-18-OCH3 (ALP) in sensitive S49wt mouse lymphoma cells and ALP-resistant S49ar variants, both with wild-type p53, and in related L1210 cells with mutated p53. Ether...

Over-expression of Bcl-2 protects against apoptosis induced by the bioreductive cytotoxic drug SR4233 (Tirapazamine).

Cell death and differentiation

Gilbert MS, Rupnow BA, Ramirez DA, Trisler KD, Knox SJ.
PMID: 17180085
Cell Death Differ. 1996 Apr;3(2):215-22.

The human B-cell lymphoma cell line PW undergoes radiation-induced programmed cell death (PCD). Bcl-2 transfected PW cells, that overexpressed Bcl-2, were significantly more radioresistant than parental or neomycin control transfected PW cells. The viability of Bcl-2 transfected cells was...

Reduction of phenoxyl radicals of the antitumour agent etoposide (VP-16) by glutathione and protein sulfhydryls in human leukaemia cells: Implications for cytotoxicity.

Toxicology in vitro : an international journal published in association with BIBRA

Yalowich JC, Tyurina YY, Tyurin VA, Allan WP, Kagan VE.
PMID: 20650183
Toxicol In Vitro. 1996 Feb;10(1):59-68. doi: 10.1016/0887-2333(95)00106-9.

Phenoxyl radicals are inevitable intermediates in the oxidative enzymatic metabolism of a phenolic antitumour drug, etoposide (VP-16), by peroxidases, cytochrome P-450, prostaglandin synthetase and tyrosinase, as well as in its interactions with oxygen and peroxyl radicals. It has been...

The modulation of intracellular glutathione level modulates the mitochondrial response in proliferating rat splenocytes.

Archives of gerontology and geriatrics

Pieri C, Marra M, Moroni F, Marcheselli F, Benatti C.
PMID: 15374208
Arch Gerontol Geriatr. 1995 Sep-Oct;21(2):115-25. doi: 10.1016/0167-4943(95)00630-4.

We have investigated the effect of intracellular reduced glutathione (GSH) levels on the mitochondrial parameters of proliferating rat splenocytes. The intracellular GSH content of the cells was altered by continuous culture with buthionine-S, R-sulfoximine (BSO), a specific inhibitor of...

High Throughput Method for Assessment of Cellular Reduced Glutathione in Mammalian Cells.

PMID: 20463849
J Environ Prot Sci. 2007 Jan 01;1:23-28.

Reduced glutathione (GSH) is an intracellular molecule essential for many aspects of cell physiology and defense. Determination of GSH has been used to identify potential anti-cancer drugs and for the assessment of drug toxicity via generation of oxidative stress....

RIP1 kinase mediates arachidonic acid-induced oxidative death of oligodendrocyte precursors.

International journal of physiology, pathophysiology and pharmacology

Kim S, Dayani L, Rosenberg PA, Li J.
PMID: 20706550
