Cancer: The origin of genetic mutations

September 25, 2019 0 Comments Brain Tumor, Cancer, Colon Cancer, Lung Cancer, Lymphoma, Prostate Cancer, Skin Cancer, Stem Cells

In the presence of some disruptive elements, cancer cells are unable to replicate its DNA optimally. While known to be linked to the increase in genetic mutations, the exact mechanism at work remained unknown until now. By deciphering how replication stress induces the loss or gain of whole chromosomes in the daughters of cancer cells, researchers provide new knowledge that will ultimately lead to better diagnosis and possibly better treatment of cancer.

New method provides better understanding of gene 'enhancers' work

Using anew method called Net-CAGE, researchers identified as many as 20,000 new enhancers in humans. They found that while promoters are activated in a variety of cell types, enhancers tend to function in just 1 cell type, thus showing an important difference between the 2 types of region.

Some colorectal cancer patients with a certain gene mutation benefit from a chemotherapy drug called cetuximab, although the mechanism of how this drug worked was unknown. Scientists have combined computational biology with experimental investigations to discover, for the first time, the mechanism for why these patients respond to cetuximab, which will help doctors identify more effective, targeted treatment plans for people diagnosed with colorectal cancer.

Pathway found for treatment-resistant lung cancer

A big way chemotherapy works is by prompting cancer cells to commit suicide, and scientists have found a pathway the most common lung cancer walks to avoid death. Scientists have found a first step appears to be lung cancer cells expressing high levels of the molecule TIMP-1, classically considered a tumor inhibitor but at high levels already associated with a poor prognosis for patients.
