چکیده

Acetylcholinesterase, an erythroid marker constitutively ex pressed in K-562 cells, can be further induced by sodium butyrate. The highest level of acetylcholinesterase induction is reached in =3 days, in parallel with increased hemoglobin expres sion. Acetylcholinesterase induction is reversible, and repeated addition of butyrate is necessary to maintain a high level of the enzyme. Actinomycin D inhibits the induction.

Regulation of acetylcholinesterase expression in the K-562 cell line.

Acetylcholinesterase, an erythroid marker constitutively expressed in K-562 cells, can be further induced by sodium butyrate. The highest level of acetylcholinesterase induction is reached in approximately equal to 3 days, in parallel with increased hemoglobin expression. Acetylcholinesterase induction is reversible, and repeated addition of butyrate is necessary to maintain a high level of the...

Evaluation of acetylcholinesterase transcript level as a biomarker of methylmercury in orange spotted grouper (Epinephelus coioides) brain

The bioavailability of methylmercury (MeHg) in the brains of  orange spotted groupers, captured from four creeks of Mahshahr embayment was measured.  Then the effects of this pollutant on the regulation of gene expression, acetylcholinesterase transcript levels was chosen in order to monitor the amounts of methylmercury concentrations in the creeks, and the fluctuations of mRNA expressions in t...

O-10: A Marked Animal-Vegetal Polarity in The Localization of Na+,K+-ATPase Activity and Its Down-Regulation Following Progesterone-Induced Maturation

Background: Polarized cells are key to the process of differentiation. Xenopus oocyte is a polarized cell that has complete blue-print to differentiate 3 germ layers following fertilization, as key determinant molecules (Proteins and RNAs) are asymmetrically localized. The objective of this work was to localize Na+, K+-ATPase activity along animal-vegetal axis of polarized Xenopus oocyte and fo...

بررسی اثر سمّ عقرب همیسکورپیوس لپتوروس بر روی میزان بقای دودمان سلولی K-562

Introduction: Chronic Myelogenous Leukemia (CML) is a malignant disease. Different drugs have been suggested for the treatment of leukemia, but none of them has resulted in complete remission. Recently scorpion toxins have been reported to have anticancer activity on several cell lines. In the present study, the effects of Hemiscorpius Lepturus scorpion was evaluated on K-562 cell line as an ex...
