BACKGROUND Glyoxalases (Glo1 and Glo2) are involved in the glycolytic pathway by detoxifying the reactive methylglyoxal (MGO) into D-lactate in a two-step reaction using glutathione (GSH) as cofactor. Inhibitors of glyoxalases are considered as anti-inflammatory and anti-carcinogenic agents. The recent finding that various polyphenols modulate Glo1 activity has prompted us to assess curcumin's ...

BACKGROUND Alternative splicing is an important mechanism that regulates gene expression and function in human cells. OCT4, a crucial pluripotency marker in embryonic stem/carcinoma cells generates several spliced variants in different cell types and cancers. The expression of OCT4 in cancers has been challenged in many studies. The existence of several OCT4 spliced variants and absence of spec...

Several studies have shown how pentacyclic triterpenes can inhibit proliferation and induce apoptosis of some tumor cell lines; however, its effect on astrocytic tumors, one of the most malignant forms of cancer, has rarely been reported. The aim of this study was to examine how the pentacyclic triterpenes, oleanolic acid and maslinic acid, isolated from olive juice, affected astrocytoma cell m...

2-Chloro-N(6)-methyl-(N )-methanocarba-2'-deoxyadenosine-3',5'- bisphosphate (MRS2279) was developed previously as a selective high-affinity, non-nucleotide P2Y(1) receptor (P2Y1-R) antagonist (J Med Chem 43:829-842, 2002; Br J Pharmacol 135:2004-2010, 2002). We have taken advantage of the N(6)-methyl substitution in the adenine base to incorporate [(3)H]methylamine into the synthesis of [(3)H]...
