MicroRNA let-7a suppresses breast cancer cell migration and invasion through downregulation of C-C chemokine receptor type 7

MicroRNA let-7a binds directly to the 3'UTR of C-C chemokine receptor type 7 (CCR7), blocking its protein expression and suppressing migration and invasion of breast cancer cells.

The distribution pattern of critically short telomeres in human osteoarthritic knees

An increase in the number of cells with ultra short telomeres is associated with increased severity of osteoarthritis, proximity to the most damaged section of the joint, and with senescence.

Reversal of type 1 diabetes via islet beta cell regeneration following immune modulation by cord blood-derived multipotent stem cells

The safe reversal of Type 1 diabetes is possible with Stem Cell Educator therapy which uses stem cells from cord blood to re-educate a diabetic's own T cells, restarts pancreatic function, and reduces the need for insulin.

The female menstrual cycle does not influence testosterone concentrations in male partners

The hypothesis that male testosterone concentrations increase with female olfactory ovulation cues is contradicted in a study which monitored thirty couples and established no significant effect, also suggesting no relevance of ovulation to male sexual drive and aggressiveness.
