Significant risk factors like breast cancer have been associated with abortion. Abortion Risks Significant risk factors like breast cancer have been associated with abortion. The morality of abortion is not directly tied to the risks it poses to the mother.
Fact checked by Jasmin Collier Some cancers put up a fight against regular treatments such as chemotherapy or radiotherapy due to their various "strategies" for survival.
This process has been shown to have complex implications for cancer cells; sometimes it helps to destroy them, but at other times it helps them to thrive.
One way in which cancer cells use autophagy "in their own interest" is to evade apoptosisor cell death. Apoptosis and autophagy both rely on similar mechanisms to break down cellular material that is no longer helpful.
But while apoptosis takes this disassembly all the way, eventually causing the cell to die, in autophagy, death is postponed by recycling some of the cellular material.
In many cases, researchers have discovered that chemotherapy and radiotherapy can increase the presence of autophagy in cancer cells, which actually allows them to enter a "hiatus" mode that helps them to evade cell death and resume their activity later.
While researchers have studied the importance of autophagy inhibitors in promoting apoptosis, the underlying mechanisms that allow cell death to occur when this recycling process is inhibited have remained unclear. The results of the study — which was led by Andrew Thorburn — have now been published in the journal Developmental Cell.
But the cells use autophagy to go into a kind of suspended animation, pausing but not dying.
We show that FOXO3a may make the difference between these two outcomes. Interestingly, though, autophagy also helps to regulate the levels of this transcription factor.
In other words, when the presence of autophagy is increased, FOXO3a levels go down, and when autophagy is downregulated, more FOXO3a is produced, thereby boosting the cellular recycling process. This means that autophagy remains at constant levels, sometimes despite the action of chemotherapy drugs.Online custom essays, term papers, research papers, reports, reviews and homework assignments.
