Microrobots-fish attack cancer cells

A group of Chinese researchers has developed a prototype of a microscopic fish robot printed on a 3D printer that can treat cancer cells directly in the human body. An achievement that could revolutionize this type of treatment, as it will destroy tumors much more purposefully, increasing effectiveness while reducing side effects.  Chemotherapy, widely used…

the gene responsible for metastasis of major cancers

Detection of a compound capable of deactivating the gene responsible for metastasis of major cancers

In 2004, a group of researchers from Princeton University identified a gene involved in the development of metastatic breast cancer: methadherin, or MTDH. By focusing their research on this single gene in two new studies, American scientists managed to neutralize it to prevent the development of cancer cells.
