US Scientists Successfully 'Switch Off' Cancer Cells
iONiUM sends news that Mayo Clinic cancer researchers have developed a technique to reprogram cancer cells in a lab, essentially "turning off" their excessive cell growth.
That code was unraveled by the discovery that adhesion proteins — the glue that keeps cells together — interact with the microprocessor, a key player in the production of molecules called microRNAs (miRNAs). The miRNAs orchestrate whole cellular programs by simultaneously regulating expression of a group of genes (abstract). The investigators found that when normal cells come in contact with each other, a specific subset of miRNAs suppresses genes that promote cell growth. However, when adhesion is disrupted in cancer cells, these miRNAs are misregulated and cells grow out of control. The investigators showed, in laboratory experiments, that restoring the normal miRNA levels in cancer cells can reverse that aberrant cell growth.
When I see it in practice with proven real world results.
Too often these promising studies generate all kinds of hype and then disappear shortly thereafter.
Political correctness is really just herd psychology pushed by insecure people who desperately seek social conformity.
