Background: Nicotine as a toxic agent in cigarette has detrimental effects on reproduction. The aim of this study was to evaluate effects of of nicotine on germ and somatic cells in adult mouse testis. Materials and Methods: Male mice were divided into four groups. Group A or controls, groups of B, C and D were treated with nicotine intraperitoneally in doses of 0.1, 0.2 and 0.4 mg/100 g body w...
AntimitoticDrugsDisrupt theNormal Function of the Mitotic Spindle and Cause Spindle Checkpoint ^MediatedMitotic Arrest Microtubule inhibitors such as Vinka alkaloids (e.g., vinblastine and vincristine) and Taxans (e.g., taxol/paclitaxel and docetaxel) are potent therapeutic drugs for cancer treatment. The cellular consequences of taxol/paclitaxel treatments over a wide range of doses (1 nmol/L–...
The grading system for pancreatic neuroendocrine tumors (PanNETs) adopted in 2010 by the World Health Organization (WHO) mandates the use of both mitotic rate and Ki67/MIB-1 index in defining the proliferative rate and assigning the grade. In cases when these measures are not concordant for grade, it is recommended to assign the higher grade, but specific data justifying this approach do not ex...
Induction of apoptosis by evodiamine involves both activation of mitotic arrest and mitotic slippage
Because of the central role of the endothelium in tissue homeostasis, protecting the vasculature from radiation-induced death is a major concern in tissue radioprotection. Premitotic apoptosis and mitotic death are two prevalent cell death pathways induced by ionizing radiation. Endothelial cells undergo apoptosis after radiation through generation of the sphingolipid ceramide. However, if mito...
DNA damage repair, loss of heterozygosity, and chromosome rearrangement are important aspects of genome stability, and all are tied to mitotic recombination. Despite the importance of mitotic recombination, the most basic questions about this process remain poorly understood. This is in part because mitotic recombination, in contrast to meiotic recombination, is rare on a per cell division basi...
