Mechanisms of environmental chemicals that enable the cancer hallmark of evasion of growth suppression.

چکیده
As part of the Halifax Project, this review brings attention to the potential effects of environmental chemicals on important molecular and cellular regulators of the cancer hallmark of evading growth suppression. Specifically, we review the mechanisms by which cancer cells escape the growth-inhibitory signals of p53, retinoblastoma protein, transforming growth factor-beta, gap junctions and contact inhibition. We discuss the effects of selected environmental chemicals on these mechanisms of growth inhibition and cross-reference the effects of these chemicals in other classical cancer hallmarks.

The potential for chemical mixtures from the environment to enable the cancer hallmark of sustained proliferative signalling.
The aim of this work is to review current knowledge relating the established cancer hallmark, sustained cell proliferation to the existence of chemicals present as low dose mixtures in the environment. Normal cell proliferation is under tight control, i.e. cells respond to a signal to proliferate, and although most cells continue to proliferate into adult life, the multiplication ceases once th...
متن کاملTax Evasion in Oil-Exporting Countries: The Case of Iran
N umerous studies have been conducted about the determinants of tax evasion. In all of these studies, this phenomenon has been taken into account in the framework of balanced budget and a non-oil economy. In this study the determinants are examined by extending an endogenous growth model and considering two cases for the government budget in an oil-exporting country along with its budget d...

متن کاملThe effect of fasting on the important molecular mechanisms related to cancer treatment
Fasting does have remarkable benefits in the treatment of cancer and another diseases such as metabolic syndrome, diabetes, and a multitude of other chronic diseases. It has been determined that fasting could play an important role during cancer treatment and progression via the regulation of insulin-like growth factor-1 (IGF-1) as well as other growth factors. Also, it has been shown that fast...
متن کاملInhibition of janus kinase 2 by compound AG490 suppresses the proliferation of MDA-MB-231 cells via up-regulating SARI (suppressor of AP-1, regulated by IFN)
Objective(s): The Janus kinase-signal transducers and activators of transcription signaling pathway (JAK/STAT pathway) play an important role in proliferation of breast cancer cells. Previous data showed that inhibition of STAT3 suppresses the growth of breast cancer cells, but the associated mechanisms are not well understood. This study aims to investigate the effect and associated mechanisms...
