This paper discusses the potential therapeutic effect of α7-nAChR antagonists for NSCLC (non small cell lung cancer) and MPM (malignant pleural mesothelioma). This therapeutic approach is based on the experimental observations that: (a) functional α7-nAChR are expressed in NSCLC and MPM cells, (b)
It has been recently reported that nicotine, the addictive component of tobacco, is an important modulator at the level of immune cell apoptosis or programmed cell death. Apoptosis is a process that helps maintain the homeostasis of the vascular endothelium and vascular smooth muscle cells, and
Nicotine, the addictive component of tobacco, is thought to be at least partially responsible for the deleterious effects of smoking such as heart disease and cancer. Evidence shows that nicotine is an immunomodulator and that one of its possible mechanisms is regulation of apoptosis, or programmed
The synthesis of some steroidal bisquaternary ammonium substances (compounds 10 and 11), and their in vitro and in vivo neuromuscular blocking action are described in this report. The pyrrolidino functionality was incorporated at both the 3-beta and 16-beta positions of the steroid nucleus to study
Nicotinic acetylcholine receptors (nAChR) are expressed on bronchial epithelial and non-small cell lung cancer cells and are involved in cell growth regulation. Nicotine (classical nAChR agonist) induced cell proliferation, whereas nAChR antagonists, d- tubocurarine or alpha-cobratoxin (alpha-CbT),
Thymopentin (Arg-Lys-Asp-Val-Tyr, TP5) has shown immuno-regulatory activities in humans. In the present study, we investigated the effects of TP5 on the proliferation and differentiation of a human promyelocyte leukemia cell line, HL-60. It is noteworthy that TP5 displayed concentration-dependent
