the characteristics of cellular and molecular mechanisms associated with cell proliferation and differentiation is important to understand malignancy. in this report we characterise a leukemic model, d5a1, to study the action of differentiation agent, cellular events and gene expression of the selected transcription factors. cells induced with 4 mm hexamethylene bisacetamide (hmba) caused signs...
dear editor: we would like to present a modified method for cerebrospinal fluid collection in anesthetized rat. this method is easy and applicable in many laboratories interested by research on cellular and molecular effects of csf on different pathways.
background: alpha particle irradiation from radon progeny is one of the major natural sources of effective dose in the public population. oncogenic transformation is a biological effectiveness of radon progeny alpha particle hits. the biological effects which has caused by exposure to radon, were the main result of a complex series of physical, chemical, biological and physiological interaction...

background: zinc (zn) as an important trace element is essential for testicular development and spermatogenesis. molecular mechanism of zn action in the reproductive system may be related to metal binding low-molecular weight proteins, metallothioneins (mt). our objective was to determine the effect of zn on two important isoforms of mt, mt1m and mt1g genes expression on testicular sertoli cell...
Mammalian mechanistic target of rapamycine (mTOR) is a conserved serine/threonine kinase in the cellular PI3K/Akt/mTOR signaling pathway. This pathway is modified by cellular alterations such as level of energy, growth factors, stresses, as well as the increased environmental level of cancerous cytokines. In general, increase of this kinase protein function is seen in various types of cancers, ...
Several factors have incentive role for study of aging which includes increasing of the average and maximum of human life span, the increase in percentage of elderly in the societies and proportion of the national expenditure utilized by them. The Recent views of aging indicating that aging is extremely a complex multifactorial process despite of earlier views about definite cause aging like ge...
Cardiovascular diseases are still the main cause of mortality around the world. Therefore, it is essential to develop practical means to reduce their burden. A wealth of evidence supports the role of physical exercise in attenuating many of the risk factors of cardiovascular diseases. Moreover, endurance training warrants protection against myocardial infarction. Exercise, even if performed ...
