objective: e1a oncoprotein of adenovirus type 5 is a regulatory factor which controls transcription of other adenovirus genes. this protein promotes both viral genom replication and host cell transformation by altering the function of certain important cellular proteins such as p21 and rb. the aim of the present study was to constantly reduce the expression of e1a gene in hek 293 cell line by r...

1 Congregation for the Doctrine of the Faith, Donum vitae (February 2, 1987), Introduction, 5. 2 Ibid., I, 1. The topic of embryonic stem cells is very much in the forefront of public interest. The moral stance on obtaining stem cells from embryos is clear: The Church has always taught that all human life from the very beginning must be respected and protected. If human embryos are killed to ob...

Because HEK-293 cells are widely used for the functional expression of channels, exchangers and transporters involved in Ca(2+) homoeostasis, the properties of intracellular Ca(2+) stores and the methods used for measuring intracellular Ca(2+) release in HEK-293 cells were evaluated. Ca(2+) imaging was used to show caffeine-, carbachol- and thapsigargin-induced Ca(2+) release in HEK-293 cells t...

Down-regulation of Kv4.3 K⁺ channels commonly occurs in multiple diseases, but the understanding of the regulation of Kv4.3 K⁺ channels and the role of Kv4.3 K⁺ channels in pathological conditions are limited. HEK (human embryonic kidney)-293T cells are derived from HEK-293 cells which are transformed by expression of the large T-antigen. In the present study, by comparing HEK-293 and HEK-293T ...

In this study, we compared the effects of terpinolene against anti-cancer agent cisplatin on proliferation, apoptotic activity and intracellular ROS (reactive oxygen species) production in cancerous (MCF-7) non-cancerous (HEK-293) cell lines. Cisplatin presented a strong growth-inhibitory effect both MCF-7 (IC25: 18.77 µM) HEK-293 15.03 The was found to be weaker than 291.18 µM for 345.35 HEK 2...

Background: Understanding of cellular and molecular mechanisms involved in cell/tumor growth and progression has led to molecular-targeted therapy. HER1 and HER2 are two main oncogenic components of HER-receptor family considered as targets for cancer research and therapy. Reliable results of HER- related research and targeted therapies dependent upon cell line with known HER expression status....
