As a consequence, such changes disturb cellular signaling pathways and regulatory circuits in affected cells conferring growth advantages, landscaping the micro-environment of the tumor cells, and supporting escape from immunosurveillance. (dkfz.de)
Concomitantly, new blood vessels are formed, inflammatory cells are recruited, and fibroblasts are activated in the surrounding tumor stroma. (dkfz.de)
The complex interactions between tumor cells and vessel, immune, or stroma cells are not yet traceable in an authentic manner in cell cultures in vitro. (dkfz.de)
By probing what happens to cells in acid regions of tumors, scientists have uncovered new information about cancer's invasiveness and spread. (medicalnewstoday.com)
There was a time when scientists believed that the potential for tumors to metastasize depended only on alterations to cancerous cells. (medicalnewstoday.com)
There is now a good understanding among scientists that tumors are not simply collections of multiplying cancerous cells, but "living entities," comprising many different types of cell. (medicalnewstoday.com)
In this way, the researchers can tag and identify cells in acidic regions of the tumors. (medicalnewstoday.com)
To do this, the tumour cells form long thin channels from their membranes, so-called tumour microtubules, that connect them to other tumour cells. (sciencedaily.com)
This network favours the spread of tumour cells, cell division and makes astrocytomas more resistant to treatment. (sciencedaily.com)
Indeed, using this network, astrocytomas are able to initiate repair mechanisms and so eliminate any damage to individual tumour cells caused, for example, by radiotherapy treatment. (sciencedaily.com)
Nearly all Ewing tumor cells have changes that involve the EWSR1 gene, which is found on chromosome 22. (cancer.org)
Activation of the EWSR1 gene leads to overgrowth of the cells and to the development of Ewing tumors, but the exact way in which this happens is not yet clear. (cancer.org)
In a very small portion of Ewing tumors, the cells have translocations that involve the FUS gene (on chromosome 16) instead of the EWSR1 gene. (cancer.org)
Lab tests can be used to find chromosome translocations in Ewing tumor cells (see Tests for Ewing Tumors ). (cancer.org)

Researchers have discovered that tumors release fatty acids that interfere with the cells that are trying to kill them. (scienceblog.com)
They discovered that tumors secrete fatty acids which inhibit the cytotoxic T lymphocytes' ability to kill tumor cells. (scienceblog.com)
First, the most common type of free fatty acids, which at normal levels are essential for life, at high levels prevents the cytotoxic T lymphocytes from destroying tumor cells. (scienceblog.com)
For example, they keep certain proteins from being phosphorylated and they also prevent an increase in intracellular calcium that is essential for the cytotoxic T lymphocytes to kill the tumor cells. (scienceblog.com)
