MicroRNA replacement provides an effective therapy in cancer
Researchers from Johns Hopkins and Nationwide Children have discovered a potential strategy for cancer therapy by focusing on what’s missing in tumors. MicroRNAs control gene expression and are commonly lost in cancerous tumors. Noticing this absence, scientists have shown that the...

A New Method for the Study of Cell Detachment
Tumor cells that detach and enter the bloodstream create the possibility for the disease to spread in other tissues. While scientists gained knowledge about how cancer cells attach to these surfaces, little is known about the way these cells detach...

The Human Epigenome and Cell-Type-Specific Gene Expression
Differences in gene expression is what causes diversity between cells despite the fact that almost all human cells have the same genome and it represents the process through which a protein or other molecule encoded by a gene is produced....

A New Approach in Understanding the Metastatic Process
In an effort of understanding the mechanisms of the metastasis, researchers at the Institute Curie in Paris came up with a theory that suggests that every biological tissue regulates to a preferred pressure called homeostatic pressure and that an increased...
