Development of Rett Syndrome Linked to Membrane Transport Protein Deficiency

Neurological disease researchers have found a potential therapeutic approach for the treatment of Rett syndrome that is based on modulation of the calcium transporter protein KCC2.  More...

Deleting the Dicer DNA-Repair Enzyme Increases Sensitivity of Cancer Cells to Chemotherapy

Blocking the activity of the enzyme Dicer in rapidly growing cancer cells prevents them from correcting DNA damage, which renders them more sensitive to the action of chemotherapeutic drugs.  More...

Cell-Free Bioreactor Produces Therapeutic Proteins for Point-of-Care Use

A microfluidic bioreactor for cell-free protein synthesis was developed to facilitate the production of a single-dose of a therapeutic protein for point-of-care delivery.  More...

Proteasome-Activating Drug Reverses Neurodegenerative Disease Symptoms in Mouse Model

Accumulation of insoluble tau protein complexes, which characterizes several types of neurodegenerative diseases, was associated with a decrease in brain proteasome peptidase activity that could be restored by treatment with a phosphodiesterase-4 inhibitor drug.  More...

Maintenance of a Stable Karyotype Depends on Action of a Long Noncoding RNA

A long noncoding RNA regulates cellular genomic stability by sequestering the PUMILIO proteins, which would otherwise drive chromosomal instability by repressing mitotic, DNA repair, and DNA replication factors.  More...

Image: Left panel: Micrograph of an undifferentiated breast tumor - densely packed with cancerous cells and with a high potential to spread. Right panel: Differentiated tumor following anti-Malat1 ASO treatment with cyst-like cells filled with fluid containing, among other things, milk proteins. Treated tumors were comparatively static with reduced metastatic activity (Photo courtesy of Spector Laboratory, Cold Spring Harbor Laboratory).

Loss of Long Noncoding RNA Inhibits Breast Tumor Metastasis in Mouse Model

Blocking the activity of a single long noncoding RNA in malignant breast cancer mouse models transformed aggressive cancers into slow growing cyst-like tumors and reversed the metastatic process by up to 70%.  More...
