Breast cancer recurrence defined by hormone receptor status

New research reveals that women with HER2 positive breast cancer that is also hormone (estrogen and progesterone) receptor negative have an increased risk of early death and less likely to recur in bone compared to those with hormone-sensitive cancer. The study suggests HR status defines two different subsets of HER2 positive cancers.

The genetics of white finger disease

A study published in Clinical Epigenetics found that individuals with a specific genetic variation in SIRT1 are more likely to develop vibration-induced white finger disease. The research suggests that testing for this variant before starting work with vibrating machinery could prevent years of pain and disability.

New weapons in the fight against cancer

Several new first-in-human studies for drugs targeting a range of cancers have shown promising results, including the development of MEK-, MET- and HSP90 inhibitors as well as immunotherapeutic strategies. Studies have demonstrated significant activity in ALK-positive lung cancer resistant to crizotinib and other targeted therapies.

Researchers discover gene that causes deafness

Researchers at the University of Cincinnati have identified a genetic mutation responsible for deafness and hearing loss associated with Usher syndrome type 1. The discovery of the CIB2 protein provides new insights into the mechanism of mechano-electrical transduction, which converts mechanical energy into sound.

Climate change could cripple southwestern forests

The study reveals that southwestern forests face significant challenges due to climate change, including increased drought stress and mortality. The researchers developed a Forest Drought-Stress Index that shows a strong correlation with tree growth, death from drought, and area burned by forest fires.
